Type locality.
Turkey, Adıyaman Province, Nemrut Dağı, NE of Adıyaman.
Notes on type locality.
The Nemrut Dağı, a mount in Southeastern Anatolia, elevated over 2150 m a.s.l., not far from the upper reaches of the Euphrates. It belongs to the Taurus Mountains and lies 86 kilometers northeast of Adıyaman in the province of the same name.
The GPS coordinates indicated on original labels are imprecise. They were taken from a map after the time of collecting (V. Vrabec, pers. comm.).
Type material.
Holotype ♂, 'S Turkey: NEMRUT DAGI / (NE from Adiyaman), UTM: DC60 / 38.00N/38.35E, 1700-1900 m / mount. pastures, stone fields / 27.-28.IV.1997, V. Vrabec lgt.' (cWR). Paratype: 1♀, labelled as holotype (NMNHS).
TME: 2 specimens. TGE: 1♂, 1♀.
Etymology.
Patronymic, named after Vladimír Vrabec, an entomologist interested in beetles and butterflies, who collected the type series of the new species.
Diagnosis.
It differs from P. vanensis sp. nov. by the uniformly lighter coloration of the body, by the elytra and strioles much less coarsely and deeply punctate, and by slightly higher value of ratio PW/ PА (1.41-1.42, vs. 1.32-1.41). The apical lamella in P. vrabeci sp. nov. is also more symmetrical and elongate (Fig. 10F View Figure 10 ) and the bursa copulatrix is rounded (Fig. 13F View Figure 13 ).
Description.
Habitus. Specimens of relatively large size for Platyderus species (BL: 7.30-7.45 mm; BW: 2.40-2.50 mm), with elongate, moderately convex body (Fig. 1F View Figure 1 ). Measurements and ratios. See Table 1 View Table 1 . Color and lustre. Body and appendages rusty red, head slightly darker than pronotum and elytra. Integument moderately shiny, head and pronotum shinier than elytra. Microsculpture and punctation. Pronotum without microreticulation. Elytral intervals and scutellum with distinct isodiametric sculpticells, basal margin and lateral gutterof elytra without evident microsculpture. Ventral surface largely with sculpticells not apparent or with scarcely-visible isodiametric (proepisternum, abdominal ventrites 1-5 laterally) or slightly transverse sculpticells (abdominal ventrite 6). Head with punctures and wrinkles only on posterior part of clypeus and areas in and around frontal furrows, rest of dorsal surface smooth. Pronotum coarsely punctate in basal third, with some punctures at sides reaching medial third; disc and apical third smooth. Elytral intervals with a row of irregular punctures. Abdominal ventrites smooth to very finely wrinkled at sides. Head. One-third or less as wide as pronotum (PW/HW= 1.38-1.42). Eyes moderately convex. Labrum subrectangular, as long as clypeus, with anterior margin slightly concave. Frontoclypeal suture distinct, impressed in middle, less distinct to obliterate at sides. Frontal furrows moderately distinct and impressed, subfoveolate. Paraorbital sulci straight, moderately deep, backward barely reaching posterior margin of eye, not reaching level of posterior supraorbital pore. Thorax. Pronotum about a quarter wider than long (PW/PL= 1.21-1.25), with widest point at second quarter. Anterior and posterior transverse impressions barely distinct. Sides sinuate, convex medially and anteriorly, concave posteriorly; bead of anterior border present throughout, rather fine; bead of posterior border present laterally and submedially, reduced to lacking at medial 1/10. Metepisternum as long as wide, MA/MI= 0.95-1.01. Elytra. Elongate, about two thirds as long as elytra wide (EL/EW= 1.63-1.66), two times and two thirds as long as pronotum (EL/PL= 2.63-2.71), and one and a third as wide as pronotum (EW/PW= 1.32), with widest point at beginning of third quarter. Parascutellar striole and striae well-impressed, moderately punctate (less coarsely than P. weiratheri and P. vanensis sp. nov.); parascutellar striole short, not joining stria 1; striae 1-6 reaching basal bead, 7 shortened a little before. Interval 3 with three discal setiferous punctures, as first lack on left eytron of paratype. Umbilicate setiferous series with 16 punctures on each side in holotype, with 17 punctures on left elytron and 15 ones on right elytron in paratype. Legs. Posterior side of profemur with one seta in basal third and one in medial third. Mesofemur with 3-4 setiferous punctures on anterior side ventrally. Anterior side of metafemur ventrally with two long setae, one in basal third and one in medial third. Male genitalia. Urite IX suboval, with proximal margin slightly asymmetrical and pointed (Fig. 7D View Figure 7 ). Median lobe of aedeagus in lateral view similar to that of P. vanensis , but slightly narrower and with apex a little longer (Fig. 8F View Figure 8 ); same in ventral view straight, about 3.2 - 3.3 times longer than wide (Fig. 10F View Figure 10 ); apical lamella (dorsal view) less symmetrical and more elongate than in P. vanensis sp. nov. Internal sac in lateral view (Fig. 8F View Figure 8 ) with ventral sclerite distinctly broadened and rounded distally; same in ventral view (Fig. 10F View Figure 10 ), with ventral sclerite somewhat more broadened distally than that of P. vanensis sp. nov. Right paramere on Fig. 12E View Figure 12 . Female genitalia (Fig. 13F View Figure 13 ). Apical gonocoxite with semi-pointed apex and two dorsolateral ensiform setae. Spermathecal canal connected in medial third of receptaculum.
Habitat.
Slopes with pastures and stone fields covered with snow patches at the time of collecting at an altitude of 1700-1900 m. Several trees in poor condition and a few flowering wild representatives of Hyacintus spp. were observed around the place of collecting (V. Vrabec, pers. comm.).
Distribution.
Nemrut Daği (Turkey, Southeastern Anatolia, Province of Adıyaman; Fig. 16 View Figure 16 ).
" Platyderus Eremoderus lassallei " species group
Notes. The species of the " Platyderus Eremoderus lassallei " and the " Platyderus davatchii " group share a synapomorphy, the distal end of the ventral sclerite of the median lobe is curved to the left (ventral view).
