Upon examination of the corresponding material, it was discovered that the two specimens in the collection presently listed as types of Throx sulcatus are, in fact, specimens of Phoberus horridus (Fabricius, 1775) (Fig. 25). The latter is a large, easily recognisable, flightless species found in the southwestern part of the Western Cape province of South Africa (Scholtz, 1980). Johan Christian Fabricius described it (originally in the genus Trox) 12 years before Thunberg described Throx sulcatus . Thunberg described Trox silphoides (also as Throx) on the same 1787 page. Harold (1872: 36) synonymized the latter nominal species with Phoberus horridus (as Trox horridus), an action with which we agree; this is the species masquerading as Phoberus sulcatus in the Thunberg collection (Fig. 25). In his more detailed redescription of Trox silphoides, Thunberg (1818: 450) mentioned that the body is dorsally convex (“supra convexus”) and the elytra are closed (“Elitra clause”) (here interpreted as being fused)—the main characteristics typically reflected in the external morphology of flightless trogid species, such as Phoberus horridus, are tightly fused elytra and a body shape convex in lateral view. Phoberus sulcatus, on the other hand, has fully functional wings, has a flatter general body profile, and its elytra separate easily; Thunberg (1818: 449) explicitly stated that this species is winged (“alato”).</p><p>It is notable that Throx sulcatus and Throx silphoides were both described on page 38 of Thunberg (1787), and are the only two nominal species of Phoberus (or Trox) described in that work. We are certain that Thunberg would not have confused Trox sulcatus with Trox silphoides, and that the two specimens of Phoberus horridus standing as such (Fig. 25) cannot be (the) syntypes of Trox sulcatus . Both Phoberus sulcatus and Phoberus horridus are morphologically well defined, readily recognisable as different species. We suspect that the type specimens of Trox sulcatus were mistakenly substituted with specimens of Phoberus horridus (i.e. Trox silphoides) in the Thunberg collection. It is clear that the red curatorial type labels (Fig. 25) currently associated with the two Phoberus horridus specimens were added more recently, as they were produced by digital printing.</p><p>Labels pinned in the drawers that contained the specimens, handwritten by Thunberg (handwriting compared in Horn et al. 1990: Teil II, plate 36, fig 17), are the only remaining evidence of the Throx sulcatus types having been in Thunberg’s collection (Fig. 25). There are no other specimens of Trox sulcatus present in the Thunberg collection. Our efforts to locate the missing syntypes in other museums (MNHB, MNHN, NHMB, NHMUK, NHMW, NHRS, NMPC, SDEI) were unsuccessful. We hence believe that the original type material of Throx sulcatus is lost.</p><p>An equivalent case of mistaken substitution was also noted for one of the two syntypes of Throx silphoides (Thunberg type No. 2142) in the Thunberg collection, which appears to have been substituted with a specimen of Phoberus caffer (Harold, 1872) (WPS, personal observation).</p><p>The Thunberg collection in Uppsala contains inconsistencies due to mistaken substitutions that require further investigation. Such substitutions are particularly likely in this collection because none of the specimens have locality labels, determination labels or labels indicating their type status. Additionally, all the handwritten name labels are pinned inside the drawers or trays instead of being attached to the specimens. This practice was not uncommon in historical collections from that era. A similar situation was recently highlighted by Costa-Silva et al. (2024) in the Joseph Banks collection in NHMUK.</p><p>Even though the types of Trox sulcatus could not be studied/traced, Harold (1872), Haaf (1953) and Scholtz (1979, 1980) clearly defined the distinguishing characteristics of Phoberus sulcatus (then as Trox), which can be readily identified from other similar species in the genus by the characteristic male genitalia (Figs 4, 18, 21).</p><p>Type specimens are important to maintain the nominal species’ stability and to avoid future misidentification. Considering that the supposed missing type specimens of Trox sulcatus from Thunberg’s collection correspond to the modern concept of Phoberus sulcatus (sensu Harold [1872], Haaf [1953] and Scholtz [1979,1980]), we understand that a designation of a neotype is necessary according to Article 75 of the ICZN (1999). Therefore, we propose the designation of a neotype here to establish the single name-bearing type specimen of Throx sulcatus . The neotype specimen fulfils the requirements of ICZN Article 75.3 (ICZN 1999). We selected a well-preserved male from Zwartskraal farm in the Western Cape province, South Africa, from the collection of the TMSA (Figs 1–5).</p><p>Additional material with precise localities examined (599 specimens).

Phallobase, elongate, subovate in dorsal view, arched in lateral view; slightly shorter than parameres. Parameres long, slender, extending beyond phallus, in dorsal aspect broadly curved down and inward (Figs 18a, 21o); parameres in lateral aspect slender basally, very broadly expanded medially (Fig. 21n), apically slender, narrowed, apices strongly decurved (never straight or projecting forward) and pointed (Fig. 21). Phallus divided into two symmetrical concave lobes (curved inwards) (Figs 4, 18b), lobes broad basally, curved sections elevated, inner margins curved (never straight) (Fig, 18c), apices rounded, flattened, pointed inwards (Fig. 18); two bladelike projections and hooks visible between parameres and phallus.</p><p>Differential diagnosis. The males of Phoberus sulcatus can be distinguished from the males of P. instabilis (Haaf, 1953) and P. erwinhaafi Strümpher, sp. nov. by the following combination of characteristics: the parameres in lateral profile are broad and distinctly enlarged in the middle (Fig. 21n); the apices are narrow and always curved downward (Fig. 21m); and the dorsal margin at the apex is always strongly curved or rounded (Fig. 21o).</p><p>The three species treated here closely resemble Phoberus cyrtus (Haaf, 1953), Phoberus fumarius (Haaf, 1953), and Phoberus caffer (Harold, 1872), and may be readily confused with them. For detailed morphological descriptions and diagnostic characters that distinguish these taxa, consult Strümpher &amp; Scholtz (2019) and Strümpher &amp; Stals (2021).</p><p>Geographic distribution. Phoberus sulcatus is presently known from the Eastern Cape, KwaZulu-Natal, the southeastern part of the Northern Cape and the eastern part of the Western Cape provinces of South Africa (Fig. 24). The distribution of Phoberus sulcatus seems to fall outside of the winter rainfall region of South Africa (roughly east of 21°E). Previously, Scholtz (1980), in his monographic revision, reported Phoberus sulcatus (s.l.) occurring as far west as Cape Town, as well as from a few localities from the northwestern part of erstwhile Cape Province [= present-day Northern Cape province] (Scholtz, 1980: 85, Fig. 170). However, during this study, we re-examined all the specimens from Scholtz (1980) that was accessible to us, as well as all other “ sulcatus -like” specimens collected from west of 21°E that have accumulated in South African museums post Scholtz (1980). We found that these specimens were either misidentified or belong to: Phoberus caffer (Harold, 1872) (see Strümpher &amp; Scholtz 2019), Phoberus fumarius (Haaf, 1953) (see Strümpher &amp; Stals 2021), Phoberus luridus (Fabricius, 1782) (see Scholtz 1980) or Phoberus planicollis (Haaf, 1953) (see Scholtz 1980). Even extensive collecting in winter rainfall areas of the Northern and Western Cape provinces over the past two decades yielded no further records of Phoberus sulcatus (WPS personal observation).</p><p>Natural history. Collection data show that adults were collected in pitfall traps baited with human dung, carrion (meat), carnivore dung, or a mixture of fresh pig dung and chicken livers. Individuals have also been collected on dried remains of various small and large mammals, such as jackals, bushbucks, cats, cattle, dogs, horses, sheep, vervet monkeys, and rhinos. Based on the collection records, Phoberus sulcatus appears to be active all year round. Immature stages are unknown.</p></div>	https://treatment.plazi.org/id/039B87A2FFF93B5CD7F2FD0AFE55F8FA	Public Domain	No known copyright restrictions apply. See Agosti, D., Egloff, W., 2009.

Haaf (1953) described Trox instabilis from 23 individuals. We studied the entire type series, which includes the male holotype (NHMB) and 22 paratypes (7 NHMB; 1 FMNH; 2 TMSA; 4 MNHN; 1 RBINS; 4 NHRS; 1 SDEI; 1 NHMW, 1 HMNH). According to the current treatment, the original type series comprises three distinct species. Eleven paratypes belong to Phoberus instabilis revalidated and new combination, nine belong to Phoberus sulcatus (this study), and two belong to the new species described herein.</p><p>Additional material with precise localities examined (502 specimens).

Body setae mostly brownish yellow.</p><p>Head (Figs 9–10): As in Phoberus sulcatus .</p><p>Pronotum (Figs 9–10): As in Phoberus sulcatus, except pronotal tubercles and ridges are higher and more prominent, punctation appears denser, pronotal surface slightly more embossed.</p><p>Scutellum (Fig. 9): Longer than wide, obround in shape; surface smooth; medio-basally depressed, depression punctate; margin smooth, tomentose.</p><p>Elytra (Figs 9–10): Relative dimensions and margins as in Phoberus sulcatus, except that the profile is somewhat flatter. Humeral calli, and sutural margin as in Phoberus sulcatus . Elytral costae distinct, even numbered costae more prominent than odd-numbered. Even-numbered costae with large raised oval to elongate tubercles, these tubercles smooth, dull shiny, each with a posterior setal tuft; tubercles on costae 2 and 4 irregularly spaced along elytral length, distance between tubercles roughly equal to or more than length of tubercles; tubercles on costae 6 and 8 widely spaced, distance between tubercles equal to or greater than length of tubercles; weak apical callosity present on fourth costal interval at top of elytral declivity. Elytral costae 2 and 4 with 7–9 tubercles for 0.75 elytral length (up to apical callosity).</p><p>Odd-numbered costae as in Phoberus sulcatus . Dorsally costae 1–4 separated from intercostae as slightly elevated bands; laterally costae 5–9 barely discernible as bands. Intercostae as in Phoberus sulcatus .</p><p>Metathoracic wings: Complete.</p><p>Ventral aspects: As in Phoberus sulcatus .</p><p>Male genitalia (Figs 7, 11, 19, 22): Symmetrical, slender, strongly sclerotised. Phallobase, subovate in dorsal view, arched in lateral view, as long as or slightly shorter than parameres. In dorsal aspect parameres long, slender, extending well beyond phallus, attenuated inward, apex narrowed, pointed, always projecting forward (never inward or down) (Figs 11, 19d). Parameres in lateral aspect evenly broad basally, sides subparallel, feebly sinuate apically (Fig. 22r; never convex or curved as in Fig. 21o), moderately expanded medially (compare Fig. 22q with Fig. 21n), apically slender, narrowed, apices long, only moderately decurved (almost straight, never strongly decurved or projecting downward as in Fig 21 m), projecting forward (Figs 22p). Phallus divided into two symmetrical lobes (Figs 11, 19); lobes broad basally, inner halve of lobe there elevated, concave (Fig. 19), lobes strongly narrowing in apical third, outside margin notched at apical third (Fig. 19f), apex of phallus narrow, apex broadly rounded and pointing inward, weakly keeled (Fig. 19e); inner margins of lobes almost parallel (Fig. 19g); two bladelike projections and hooks visible between parameres and phallus.</p><p>Differential diagnosis. Phoberus instabilis revalidated and new combination is the most similar to Phoberus sulcatus, but males can be distinguished from the latter by the following combination of characteristics: the parameres in lateral profile are broad, weakly expanded medially (Fig. 22q); their apices are long, narrow and weakly curved downward (Fig. 22p); and the dorsal margin at the apex is primarily straight and feebly concave (Fig. 22r). Furthermore, in Phoberus instabilis the lobes on the phallus are broad and not strongly concave as in Phoberus sulcatus (compare Figs 18 and 19). Also, see Table 1 for additional characteristics.</p><p>Geographic distribution. Phoberus instabilis is known from Botswana, Lesotho, South Africa and Zimbabwe (Fig. 24). In South Africa, the species has been recorded from the Free State, Gauteng, Limpopo, Mpumalanga, North West and Northern Cape provinces.</p><p>Natural history. Based on label data, adult beetles have been collected at light in the night and from the remains of a dead sheep. Collection records show Phoberus instabilis to be active from August to May. Immature stages are unknown.</p></div>	https://treatment.plazi.org/id/039B87A2FFF33B46D7F2FF4AFEA2F8B2	Public Domain	No known copyright restrictions apply. See Agosti, D., Egloff, W., 2009.

Located on the central plateau of Namibia, the approximate elevation of this farm is 1,700 m above mean sea level. In the pertinent collecting notebook of Sebastian Endrödy-Younga, collector of the holotype, this locality is annotated with “Farm de Wet”. We could not trace a farm called “De Wet” in Namibia, hence we assume that De Wet, a fairly common Afrikaans surname, was the surname of the owner of, or farmer on, the farm Regenstein when part of the type series was collected there.</p><p>Type material (28 type specimens).

Convex, elongate oval, elytral margins almost parallel, elytral profile convex, broadly rounded, not strongly declivous posteriorly (with no clear transition to the declivity), attaining maximum height at middle.</p><p>Colour (Figs 13–14): Matt black. Body setae mostly brownish yellow.</p><p>Head (Figs 13–14): Surface sculpted, punctate (medially) to rugulose (laterally), punctures close (interspaces varies between equal to or less than puncture diameters). Clypeus obtusely triangular, feebly convex, disc slightly elevated, apically deflexed and rounded; clypeal margin entire, smooth; clypeogenal and frontoclypeal sutures distinctly raised; frontoclypeal suture complete, with a low indistinct clypeogenal tubercle present on either side, tubercles punctate. Frons raised, with paired, arched, setose frontoclypeal carinae delimiting two semicircular depressions, separated by distinct elevated longitudinal median carina (ridge); carina punctate, arched carinae on frons marked by row of erect, stout seta. Genal angles obtuse; genae shape triangular, wide, recurved, genal surface depressed, coarsely sculpted; genal margin with distinct row of long thin straight setae. Eyes large and bulbous, scarcely visible in dorsal view. Antennal scape rounded, longer than wide, surface punctate, with long light brownish yellow setae; pedicel attached apically; antennal club brown, velutinous; setae around mouthparts dense, yellow to rust-brown. Labrum shape asymmetric; surface of labrum coarsely punctate, each puncture bearing a long stout seta.</p><p>Pronotum (Figs 13–14): Pronotal width only slightly narrower than elytra, widest at base. Lateral margins broad, explanate and curved, irregular, coarsely dentate, attenuate anteriad, with fringes of broad spatulate setae; anterior angles acute, posterior angles almost right angled. Base of pronotum distinctly marginate (bordered) and projecting backward with weakly produced posteromedian lobe; base obliquely truncate laterally behind posterior angles; basal margin with dense fringe of spatulate setae; basal edge with distinct posteromedian notch (at scutellum), edge sinuate on either side of notch.

Phallobase subovate in dorsal view, arched in lateral view, slightly longer than parameres. Parameres slender, long, extending beyond phallus, in dorsal aspect curved inward; parameres thin in basal half, more thickened in apical half (Figs 16, 20); apex narrowed, pointed, always projecting forward (never inward or down) (Figs 20h, 23s); parameres in lateral aspect slender, almost straight (never curved or convex), sides subparallel (never expanded medially; Figs 16, 23t), apically slender, narrowed, apices short, only feebly decurved (almost straight, never strongly decurved or projecting downward as in Phoberus sulcatus), projecting forward (Fig 23s). Phallus divided into two symmetrical lobes (Figs 16, 20); lobes broad basally, surface there slightly depressed (Fig. 20l), lobes strongly narrowing in apical third, outside margin distinctly notched at apical third (Fig. 20j), apex of phallus narrow, rounded, projecting upward (cf. keeled) (Fig. 20i); inner margins of lobes feebly concave to almost straight (never strongly concave), parallel and close (Fig. 20k); two bladelike projections and hooks visible between parameres and phallus.</p><p>Variation. Size: length 10.1–12.8 mm, width 5.4–6.6 mm. Arrangement, number and shape of tubercles on the even- and odd-numbered costae variable between individuals. Secondary characteristics are limited to the protibia (if not worn down): in males, the apex of the protibia is bidentate (teeth narrow, equal); protibia of males narrower than in females; females have the protibal apex not distinctly bidentate (teeth partly fused, outer tooth wide, round), protibia slightly broader than in males. No other differences were observed in the external morphology of either males or females.</p><p>Diagnosis. Phoberus erwinhaafi Strümpher, sp. nov., is most similar to P. instabilis revalidated and new combination, but males of the new species can be distinguished from the latter by the following combination of characteristics: the parameres in lateral profile are more slender, fairly straight and not expanded medially (Fig. 23t); apices are also shorter and straighter (Fig. 23s); Furthermore, in Phoberus erwinhaafi Strümpher, sp. nov. the lobes on the phallus are broad and the inner margin weakly concave and close, not straight as in P. instabilis revalidated and new combination (compare Figs 19g and 20k). Also, see Table 1 for additional characteristics.</p><p>Geographic distribution. The species is known from Namibia and the Kgalagadi Transfrontier Park in the Northern Cape province of South Africa (Fig. 24).</p><p>Natural history. There are collection records from carrion (meat). Based on label data, Phoberus erwinhaafi Strümpher, sp. nov. is primarily active in the austral summer (September to May). Immature stages are unknown.</p><p>Etymology. This new species is named after Dr Erwin Haaf, German entomologist associated with the Museum G. Frey (Germany), in recognition of his significant contributions to the study of Trogidae .</p></div>	https://treatment.plazi.org/id/039B87A2FFEE3B4ED7F2F891FB34FEAA	Public Domain	No known copyright restrictions apply.
