- Drilus obscuricornis Pic, 1899 (Figs 6, 17, 26, 38) Drilus obscuricornis Pic, 1899: 205. Type material. Holotype, male, "Asie Min., Brousse, Pic 1899 [printed label], Type [handwritten], Type [printed red label], obscuricornis Pic [handwritten]" (MHNP). Type locality. Turkey, "Anatolie, Brusse" [= Bursa]. Diagnosis. Drilus obscuricornis shares more or less uniform body coloration and weakly pectinate antennae with D. badius sp. nov., D. huijbregtsi sp. nov., and D. turcicus sp. nov. However, D. badius sp. nov. is lightly colored and has finer, less distinct pronotal punctation (Figs 2, 6), D. huijbregtsi sp. nov. has finer, less distinct pronotal punctures and more slender male genitalia (Figs 14, 17, 35, 38), and D. turcicus sp. nov. has a wider clypeus and short rounded paramera (Figs 38, 43). Description. Male (holotype). Body 3.0 times longer than width at humeri, dark brown to black, covered with yellow pubescence (Fig. 6). Head including eyes about as wide as anterior margin of pronotum (Fig. 17), dorsally with irregularly shaped depression, rugose, lateral margins above antennal sockets elevated, with large shallow punctures, with sparse semierect pubescence; clypeal margin narrowed, almost straight. Eyes medium-sized, their frontal distance 1.8 times eye diameter. Mandibles curved, incisor margin with short tooth medially. Labrum transverse, partly hidden by clypeus; maxillary palpi slender, apical palpomere obliquely cut. Antennae weakly pectinate, reaching one third of elytral length, antennomeres 3–4 serrate, antennomeres 5–10 slightly pectinate, apical antennomere simple, longest (Fig. 26). Pronotum slightly convex, transverse, widest at middle, 1.5 times wider posteriorly than length at midline. Anterior margin slightly concave, lateral margins convex, widened, slightly turned upward near posterior angles; posterior margin slightly emarginated at middle. Anterior angles inconspicuous, posterior angles distinct, rectangular (Fig. 17); surface of disc sparsely covered with large shallow punctures, with sparse semierect setae, mainly at angles and lateral margins. Scutellum flat, gradually narrowed; apex rounded. Prosternum transverse, with deep transverse groove near frontal margin, frontal margin almost straight, prosternal process short, sharp, slightly elevated medially. Mesoventrite v-shaped, grooved medially. Elytra subparallel-sided, slightly rugose, shallowly punctured, covered with semierect pubescence. Legs slender, slightly compressed, with sparse, long, semierect setae, tarsomeres 1–4 gradually shortened, tarsomere 4 shortest, apical tarsomere longest, slender, slightly longer than combined lengths of tarsomeres 3 and 4. Aedeagus compact, with considerably curved phallus; paramera robust; phallobase wide, u-shaped (Fig. 38). Female and immature stages are unknown. Measurements. BL 5.4 mm, EL 4.3 mm, WHe 1.1 mm, WHum 1.8 mm, PL 1.0 mm, PW 1.5 mm, Edist 0.7 mm, Ediam 0.4 mm. Distribution. Western Turkey (Bursa Province; Fig. 55).
