Treatment

Drilus huijbregtsi sp. nov.

( Figs 3 View FIGURES 1 – 12 , 14 View FIGURES 13 – 21 , 23 View FIGURES 22 – 33 , 35 View FIGURES 34 – 45 )

Type material. Holotype, male, "Amasia, Coll. D. A. Reclaire, Drilus concolor Ahr. E. le Moult" ( RMNH).

Type locality. Turkey, Amasya.

Diagnosis. Drilus huijbregtsi sp. nov. is similar in habitus and coloration to D. turcicus sp. nov. These species differ in the shapes of clypeus, antennae ( Figs 23, 31 View FIGURES 22 – 33 ) and male genitalia ( Figs 35, 43 View FIGURES 34 – 45 ).

Description. Male (holotype). Body 3.3 times longer than width at humeri, dark brown to black, trochanters and tarsi brown; body covered with light brown pubescence ( Fig. 3 View FIGURES 1 – 12 ). Head including eyes slightly wider than anterior margin of pronotum ( Fig. 14 View FIGURES 13 – 21 ), dorsally with wide shallow depression, covered with large shallow punctures, with sparse semierect to erect pubescence; clypeal margin widely concave. Eyes medium-sized, their frontal distance 2.0 times eye diameter. Mandibles curved, incisor margin with short conspicuous tooth medially. Labrum transverse; maxillary palpi slender, apical palpomere obliquely cut. Antennae pectinate (only two and eight antennomeres present of left and right antenna, respectively); antennomere 3 long, serrate, antennomeres 4–8 pectinate ( Fig. 23 View FIGURES 22 – 33 ). Pronotum slightly convex, transverse, widest at middle, 1.6 times wider than length at midline. Anterior margin almost straight, lateral margins convex, widened; posterior margin bisinuate. Anterior angles inconspicuous, posterior angles rectangular ( Fig. 14 View FIGURES 13 – 21 ); surface of disc sparsely covered with fine shallow punctures, with sparse semierect to erect pubescence, pubescence denser at angles. Scutellum flat, gradually narrowed, wrinkled; apex widely rounded. Prosternum transverse, slightly wrinkled, frontal margin almost straight, posterior margin widely convex, steeply declivitous, prosternal process inconspicuous. Mesoventrite widely v-shaped, with groove anteromedially. Elytra relatively long, subparallel-sided, slightly wrinkled, 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, longer than combined lengths of tarsomeres 3 and 4. Penultimate ventrite medially with deep rounded emargination. Aedeagus with robust, considerably curved phallus; paramera rather short, slightly membranous apically; phallobase long, u-shaped ( Fig. 35 View FIGURES 34 – 45 ). Female and immature stages are unknown.

Measurements. BL 6.4 mm, EL 4.4 mm, WHe 1.3 mm, WHum 1.9 mm, PL 1.0 mm, PW 1.6 mm, Edist 0.9 mm, Ediam 0.4 mm.

Distribution. Northern Turkey (Amasya Province; Fig. 55 View FIGURE 55 ).

Etymology. This species is named after Dr. Hans Huijbregts (RMNH, Leiden, Netherlands).
