Diagnosis.

Coloration, structure of head, thorax and pregenital abdomen, and vestiture as in other species of the genus (see redescription of Rhyncholepta  above) except the following characters:

Apex of scutellum with anteapical black V-shaped stripe usually reduced to small black spot at lateral margin at anterior end of apical V-shaped callosity (Figs 14-17). However, two examined males (♂ [Figure 18], French Guiana, Camp Caimans, 20.-31.i.2016, NMPC; ♂, French Guiana, Pied Saud, DBTC), have the black V complete. Apical callosity large, branches of the V short, forming ca. one third, less frequently one half, of length, tip of scutellum therefore with rather large triangular callosity (Figs 14-18).

Male genitalia. Genital capsule in ventral view distinctly constricted lateroapically (Figs 30: arrow, 54: arrow), posterolateral angles prominent, ca. rectangular (Figs 30, 54); dorsal wall at base of posterolateral angles deeply impressed (Figs 54: arrow, 66). Ventral rim in ventral view apically bilobed, with shallow V-shaped notch medially (Figs 30-31); hypandrial projections not visible in ventral view (Figs 30-31). Hypandrium in posterior view with pair of large-lobe like anterior projections, apices appearing rounded (Figs 42, 43: ap) and very short, pointed posterior projections directed posterolaterad (Figs 42, 43: pp); lateral projections not visible in ventral view but placement of their attachment apparent as small convexity laterally on anterior projections (Figure 43: lpb). Anterior hypandrial projection in most exposed (dorso-posterolateral) view larger than in Rh. grandicallosa centroamericana  , with lateral margins parallel-sided in middle, broadly rounded apically (Figure 72: ap). In dorsal view, apices of anterior hypandrial projections directed straight upwards, their median outline regularly convex (Figs 54, 55: ap; straight in Rh. g. centroamericana  ); lateral hypandrial projections long, golf-club shaped, their "handles" approaching apically (Figs 54, 55: lp; nearly parallel in Rh. g. centroamericana  ), apically regularly (C-shaped) curved inwards (Figs 55: lp, 72: lp). Phallus (Figs 78-80; described and illustrated in detail by Becker and Grazia-Vieira 1971: figs 6, 7, 10): Basal plates U-shaped. Phallotheca cylindrical, curved dorsally at right angles at apex. Conjunctiva variably sclerotized ventrally, with pair of laminar sclerites flanking distal region of aedeagus, but not reaching phallotreme (Figure 79: cjs); dorsally with strong expansion giving conjunctiva sacculiform appearance. Aedegaus (= vesica) elongate, S-shaped, covered with conjunctiva except at apex ( Becker and Grazia-Vieira 1971: fig. 10; in Figure 79: ae the S-shaped sinuation less prominent due to overmaceration in KOH).

Female genitalia. Posterior edges of laterotergites VIII abruptly attenuated apically, as long as or slightly more prominent posteriad compared with laterotergites IX (Figure 90). Internal female genitalia described in detail by Becker and Grazia-Vieira (1971: figs 14, 16).

Measurements. See Table 1. Measurements of candidate neotype (in mm): Body length 12.07, body length to segment VII 10.85, head length 2.35, head width 2.25, interocular width 1.03, length of antennomeres: I - 0.83, IIa - 1.23, IIb - 2.50, III - 3.43, IV - 2.94, pronotum length 2.55, pronotum width 8.24, scutellum length 4.41, scutellum width 3.53.

Differential diagnosis.

See characters in the key above. Most specimens of this subspecies differ from Rh. henryi  sp. n. by the incomplete black V-shaped band anteapically on scutellum; however, this character does not work for all specimens.

Etymology.

The species name is a composed Latin adjective, grandicallosus (-a, -um), meaning "bearing large callosities."

Bionomics.

Specimens mainly were collected by various types of light traps (UV light, mercury vapor light, GemLight and Polyvie traps) in dense forests or adjacent to such a forest, except in Macouria, where one specimen was collected in the littoral secondary forest and one in the savanna. This species has never been collected by hand catching, sweeping, or beating the vegetation during the day or night. One specimen was collected by flight intercept trap at Matiti, French Guiana (JE Eger, pers. observ.; R Lupoli, pers. comm.). Collection dates of specimens examined indicate that Rh. g. grandicallosa  occurs year round, with a distinct peak in April–June (Figure 94) ( Becker and Grazia-Vieira 1971, Castro Huertas et al. 2005, this paper).

Distribution

(Figs 99-100). Brazil: Amazonas ( Becker and Grazia-Vieira 1971, Arnold 2011, Silva et al. 2018); ?Colombia: Chocó ( Torres Gutiérrez 2005, as Rhyncholepta  sp.; Castro-Huertas et al. 2015); French Guiana ( Becker and Grazia-Vieira 1971); Guyana (new country record); Peru (new country record); Suriname (new country record); Venezuela ( Becker and Grazia-Vieira 1971, Grazia 1984).

Records from Colombia, Guyana, and Suriname require confirmation based on males. The subspecific identity of Rh. grandicallosa  population from Chocó, Colombia requires revision.

Comments.

Bergroth (1911) described the species based on the female sex, but did not indicate the number of specimens (syntypes) examined, though the fact that a single measurement and not a range was given for the body length ('Long. ♀ (sine membr. [= without membrane]) 11 mm) suggests that he had only one specimen. Bergroth (1914: fig. 6) provided a color painting of an adult. Neither of the Bergroth’s two papers mentioned the depository of the type(s).

Pirán (1956: 29, 35: fig. 1) illustrated the male genitalia of a specimen from Bolivia and designated the specimen as the allotype. The designation of a male allotype by Pirán (1956) is an invalid action without nomenclatural consequence because his specimen was not a part of the original type series (see ICZN 1999: Article 72). Furthermore, his illustration more closely conforms to Rh. meinanderi  as described by Becker and Grazia-Vieira (1971).

Becker and Grazia-Vieira (1971: 396) referred to a female holotype from French Guiana, deposited in the collection of the MZHF. We consider the action of Becker and Grazia-Vieira (1971: 396) as a valid lectotype designation under Article 74.6 ( ICZN 1999) because the term holotype was used explicitly for the only existing (syn)type specimen. Becker and Grazia-Vieira (1971) distinguished two species of the genus Rhyncholepta  . They interpreted Rh. grandicallosa  based on their examination of the lectotype and described its male and a new species, Rh. meinanderi  , which differs from Rh. grandicallosa  in structure of the male and female genitalia ( Becker and Grazia-Vieira 1971: figs 2, 3 versus 4, 5 and 12 versus 13).

Our revision of the genus Rhyncholepta  , however, reveals five taxa that are indistinguishable based on coloration, structure of body and pregenital abdomen, vestiture, and morphometric characters (see Table 1). The most promising external character, the development of the black V-shaped anteapical band on the scutellum and its apical V-shaped callosity, might help in identifying specimens of Rh. grandicallosa grandicallosa  versus Rh. henryi  , but we found two males of Rh. g. grandicallosa  from French Guiana with a complete V-shaped band on the scutellum, as in Rh. henryi  . This character also varies widely in Rh. grandicallosa centroamericana  . The painting by Bergroth (1914), depicting almost certainly the lectotype of Rh. grandicallosa  , shows an apparent black V-shaped band anteapically on the scutellum. The black V-shaped band, however, is not well delimited in recent photographs of the lectotype (see Figure 5), which might be attributed to inaccuracy of the painting or fading of the specimen’s coloration during a century of preservation.

The female external genitalia allow Rh. meinanderi  to be distinguished from both subspecies of Rh. grandicallosa  and Rh. henryi  sp. n., but those taxa cannot be reliably separated based on this character (Figs 93 versus 90-92). Also, the internal female genitalia did not provide suitable identification characters. Moreover, the female of Rh. wheeleri  sp. n., the taxon probably most closely related to Rh. meinanderi  , remains unknown.

The structure of the male genital capsule and, to a lesser extent, of the phallus thus remain the only reliable characters for identifying species of Rhyncholepta  . The presence of two sympatric taxa in French Guiana, the type locality of Rh. grandicallosa  , required reconsideration of the identity of this taxon. Careful examination of the photographs of the lectotype provided by MZHF confirmed that, in the absence of a reliable character allowing identification of female Rh. grandicallosa  and Rh. henryi  , the lectotype is not sufficient to determine the specific identity of Rh. grandicallosa  . We decided to follow Article 75.5 of ICZN (1999) by petitioning the International Commission on Zoological Nomenclature to suppress the existing non-informative lectotype and replace it with a male neotype. Herein we suggest a suitable male neotype, which is properly documented to fulfill all requirements of Article 75.3 of ICZN (1999) and conserves the identity of Rh. grandicallosa  sensu Becker and Grazia-Vieira (1971) and all subsequent authors. The case is being submitted to the ICZN simultaneously with this paper (Kment et al., submitted).
