Type locality. Lebanon.

Type series. In the MNHN collection, separated from coll. Desbrochers, there are two males designated by Dieckmann (1968) as a lectotype and a paralectotype of “ Anthonomus baudueri Dbr. ”. The lectotype bears the labels “Leban / type ”. Although the locality does not correspond to the original description, Dieckmann (1968) decided to designate this specimen as a lectotype because of its good match to the original description, and the handwritten label “ type ”. Another specimen sold to Heyden labeled as a “ type ” belongs to A. stierlini Desbrochers and was excluded from the syntype series by Dieckmann (1968). I share the opinion of the first revising author and regard this specimen as a valid lectotype. I dissected the genitalia.

Synonyms. In the original description of Anthonomus baudueri var. abeillei , there is no locality given. Dieckmann (1968) did not find types of this taxon in the Desbrochers´collection. In the series of Bradybatus abeillei Desbrochers in the collection of Abeille de Perrin ( MNHN), there is a pair of specimens belonging to Persexarthrus that correspond to the original description. I dissected the genitalia of both specimens and designated the male as a lectotype. The lectotype is 3.25 mm long, is with a missing right antenna and is labeled “ Abeillei Desb. Liban / 1122 / MUSEUM PARIS Collection Abeille de Perrin 1919 / Michael Košťál reprep. 2013 / LECTOTYPUS Anthonomus baudueri var. abeillei Desbrochers Michael Košťál des. 2013 [red printed]“. The heavily damaged female with the original label „ Abeillei Db.“ was designated as paralectotype. Both specimens are conspecific with the lectotype of A. baudueri .

Anthonomus cyprius was described based on 10 specimens bred from buds of Persica vulgaris collected in Cyprus. There are eight males and two females in the Marshall collection ( BMNH). Two males and both females bear labels “ PARALECTOTYPUS ... Design. Dieckmann”. As this designation was never published I designated a 2.80 mm long, completely preserved male, glued on a triangular mounting-board as a lectotype of A. cyprius Marshall. The lectotype is labeled “ Type [red margined circle] / CYPRUS Bred from peach buds IV. 1925 D. S. Wilkinson / Pres. by Imp. Bur. Ent. Brit. Mus. 1925-269. / Anthonomus cyprius, Mshl. TYPE. ♂ / LECTOTYPUS Anthonomus cyprius Marshall Michael Košťál des. 2013 [red printed]”. The remaining specimens with the same locality labels, six of which (5 ♂♂, 1 ♀) bear a pink label “ BRED peach buds...” were designated as paralectotypes. All 10 specimens are conspecific with the lectotype of A. baudueri and were labeled accordingly “ Anthonomus baudueri Desbrochers Michael Košťál det. 2013”.

Bradybatus ornatoides View in CoL was described from Lebanon (Beirut) with a remark on the similarity to Anthonomus amygdali Hustache View in CoL (as “ Anthonomus ornatus Reiche View in CoL ”), the six-segmented funicle apparently misleading Reitter to place the species in the genus Bradybatus View in CoL . The number of type specimens was not mentioned. One can assume from the locus typicus and the original description that the object of Reitter´s description was a female of A. baudueri View in CoL , as suspected by Dieckmann (1968). All characters mentioned in the original description correspond perfectly to a female of A. baudueri View in CoL . The type is known to be lost. Neither myself nor Dieckmann (1968) could locate the type in either part of Reitter’s collection (HNHM, NMW) or in the Stierlin collection (DEI). Therefore, in the interest of nomenclatural stability I decided to designate a neotype in accordance with the provisions of Article 75 of the Code (ICZN 1999). It is a perfectly preserved female, 3.27 mm in length and fully corresponding to the original description of Bradybatus ornatoides View in CoL . The neotype is labeled as follows: “Hasrun Liban Toursa 17.4. 26 W. Wittmer / NEOTYPUS Bradybatus ornatoides Reitter Michael Košťál View in CoL des. 2013 [red printed]“ and is deposited in the MSNM collection.

Redescription. Male ( Fig. 14 View FIGURES 14 – 22 ). Length 2.6–3.3 mm. Body: moderately slender, sides slightly broadened posteriorly. Rostrum: blackish, length (Rl/Pl ≈ 1.4); in lateral view evenly curved, very slightly broadened to apex; in dorsal view parallel from base to antennal insertion, distal part markedly broadened to apex, densely striatepunctate from base to apex, in basal half with whitish seta-like recumbent scales. Head: frons of same width as rostrum, very densely and finely sculptured, with white seta-like scales directed laterally; eyes prominent. Antennae: Reddish brown with darkened club, inserted at about 2/3 of rostrum length; funicular segment 1 2.5x longer than wide, segment 2 hardly twice as long as wide; club spindle-shaped, about twice as long as wide. Pronotum: blackish brown with reddish anterior margin, with large rounded regular punctures, intervals between punctures narrower than their diameter; on sides and in middle line densely covered with whitish and yellowish recumbent seta-like scales forming lateral broad and medial narrow longitudinal white lines on pronotum disc, between white areas intermixed sparse black subrecumbent setae; transverse (Pw/Pl ≈ 1.50), broadest shortly after middle, with unequally rounded sides, slightly and broadly constricted in anterior third, nearly flat on disc. Elytra: Dark brown except reddish brown interstriae 2–4 in third quarter of elytral length; moderately long (El/Ew ≈ 1.5), diverging posteriorly, widest at 3/4 of length, flat on disc. Striae and interstriae visible only on sparsely squamose parts, whitish recumbent seta-like scales densely covering scutellum, anterior part of interstria 6 creating short longitudinal lateral band. Anterior part of elytral disc densely squamose, forming subtriangular macula with posteriorly divergent margins from scutellum until one-half of elytral length. Transverse band in posterior one-half and patch on interstriae 4–5 shortly before apex as well as elytral apex itself densely whitish squamose, in middle of transverse band scales yellowish. Elytra, except densely white squamose parts, with sparse black subrecumbent setae. Legs: Brown, with tarsi, except darkened tarsomere 3, distal half of tibiae, femorotibial junction and basal parts of femora reddish to yellow, covered with whitish recumbent to subrecumbent seta-like scales; profemora with large triangular tooth and marked emargination between tooth and femoral apex ( Fig. 1 View FIGURES 1 – 4 ), meso- and metafemora with small sharp tooth; tarsomere 3 bilobed and distinctly wider than tarsomere 2, tarsomere 3 slightly shorter than tarsomeres 1–2 combined; claws simple. Venter: Uniformly covered with white seta-like scales; medial part of metasternum, ventrite 1 and 2 with clearly visible, large round punctures partially blending into rough transverse furrowing. Penis: Fig. 5 View FIGURES 5 – 8 a–c. Plates of sternite IX: Fig. 5 View FIGURES 5 – 8 d.

Female ( Fig. 15 View FIGURES 14 – 22 ). Length 2.7–3.5 mm. As in male except integument lighter in color, reddish brown; rostrum slightly longer (Rl/Pl ≈ 1.6), visibly narrowed in distal part between antennal insertion and apex, finely punctured, with antennal insertion at or shortly behind middle of rostrum; recumbent scales on pronotum yellowish, scaling of elytra markedly reduced, mostly to transverse band and apical patches. Spermatheca: Fig. 9.

Variability. Male rostrum in basal half sometimes with feebly visible medial carina. Pronotum often without reddish anterior margin. Black subrecumbent setae on pronotum and elytra often absent. Dorsal subtriangular macula of white scales on elytra varies considerably in its size and shape. Tarsomere 3 in males sometimes lighter in color. Tibiae may be entirely reddish in some males.

Diagnosis. Characteristic of this species are the relatively large triangular tooth on the profemur with an emargination between the tooth and femoral apex and the bilobed tarsomere 3, which is markedly wider than tarsomere 2.

Comparative notes. The most closely similar species to A. baudueri are A. brevispinus and A. variabilis each of which has a small tooth on the profemur and a narrow tarsomere 3.

Biological notes. Marshall (1925) reported rearing this species (as A. cyprius ) from peach buds ( Prunus persica (Linnaeus) Batsch ). I have repeatedly collected A.baudueri in Jordan (Sakib, Bir Khidad) by beating Prunus dulcis (Miller) D. A. Webb and in Syria (Al Sihl) from Prunus sp. in the second half of their blossoming period.

Distribution. Cyprus, Lebanon, Syria, Israel, Jordan.
