Treatment

Drilus turcicus sp. nov.

( Figs 11 View FIGURES 1 – 12 , 21 View FIGURES 13 – 21 , 31 View FIGURES 22 – 33 , 43 View FIGURES 34 – 45 )

Type material. Holotype, male, " Turcia, Drilus longulus det. J. Frivaldszky, 661 216" ( HNHM); paratype, male, same data as for the holotype ( HNHM).

Type locality. Turkey (with no additional data).

Diagnosis. Drilus turcicus sp. nov. is similar to D. huijbregtsi sp. nov., but differs from the latter by the less pectinate antennae ( Figs 23, 31 View FIGURES 22 – 33 ), wider clypeus, and shorter paramera ( Figs 35, 43 View FIGURES 34 – 45 ).

Description. Male (holotype). Body 3.0 times longer than width at humeri, dark brown to black, antennomeres, apical parts of tibiae and tarsi gradually lighter, light brown; body covered with yellowish pubescence ( Fig. 11 View FIGURES 1 – 12 ). Head including eyes slightly narrower than anterior margin of pronotum ( Fig. 21 View FIGURES 13 – 21 ), dorsally with wide shallow depression, lateral margins above antennal sockets elevated, distinctly punctured, with sparse semierect to erect pubescence; clypeal margin almost straight. Eyes medium-sized, their frontal distance 2.3 times eye diameter. Mandibles curved, incisor margin with robust tooth in middle part. Labrum transverse; maxillary palpi slender, apical palpomere obliquely cut. Antennae weakly pectinate, reaching one third of elytral length, antennomeres 3–5 serrate, antennomeres 6–10 weakly pectinate, apical antennomere simple, longest ( Fig. 31 View FIGURES 22 – 33 ). Pronotum slightly convex, transverse, widest at middle, 1.7 times wider than length at midline. Anterior margin medially with small emargination; lateral margins convex, widened, slightly elevated posteriorly; posterior margin bisinuate. Anterior angles inconspicuous, posterior angles obtuse ( Fig. 21 View FIGURES 13 – 21 ); surface of disc sparsely covered with sparse distinct punctures, with sparse semierect setae, pubescence denser at angles and lateral margins. Scutellum flat, longer than wide, gradually narrowed towards apex, distinctly punctured; apical part rounded. Prosternum transverse, wrinkled, with deep transverse groove near frontal margin; frontal margin almost straight, prosternal process short, steeply declivitous. Mesoventrite v-shaped, with oval cavity medially. Elytra relatively long, subparallel-sided, with longitudinal keel running from humeri toward apex, wrinled (mainly basally), 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 with short, robust, considerably curved phallus; paramera short, rounded; phallobase long ( Fig. 43 View FIGURES 34 – 45 ). Female and immature stages are unknown.

Variability. The paratype is generally slightly lighter than the holotype, especially the elytra and apical antennomeres.

Measurements. Holotype. BL 5.6 mm, EL 4.3 mm, WHe 1.3 mm, WHum 1.9 mm, PL 1.0 mm, PW 1.7 mm, Edist 1.0 mm, Ediam 0.4 mm. Paratype. BL 5.9 mm, EL 4.5 mm, WHe 1.3 mm, WHum 1.8 mm, PL 1.0 mm, PW 1.7 mm, Edist 0.9 mm, Ediam 0.4 mm.

Distribution. Turkey (no additional data known).

Etymology. The species name is derived from the country of origin.
