Treatment

Drilus teunisseni sp. nov.

( Figs 10 View FIGURES 1 – 12 , 20 View FIGURES 13 – 21 , 30 View FIGURES 22 – 33 , 42 View FIGURES 34 – 45 )

Type material. Holotype, male, " Turkiye, Anamur – Anamuryum, 9.–12.V.1991, A. Cox/H. Teunissen; Drilus cf. funebris, det. A. Teunissen 1997" ( PCAT); two paratypes, males, the same data as for the holotype ( PCAT).

Type locality. Turkey, Anamur – Anamuryum.

Diagnosis. Drilus teunisseni sp. nov. shares serrate antennae with D. latithorax , but differs from the latter by the short clypeus, relatively shorter antennae and more transverse pronotum ( Figs 4, 10 View FIGURES 1 – 12 , 15, 20 View FIGURES 13 – 21 ).

Description. Male (holotype). Body 3.3 times longer than width at humeri, dark brown to black, mouthparts, scape, pedicel and scutellum slightly lighter, legs brown; body covered with yellow to light brown pubescence ( Fig. 10 View FIGURES 1 – 12 ). Head including eyes about as wide as anterior margin of pronotum ( Fig. 20 View FIGURES 13 – 21 ), dorsally with wide shallow depression, coarsely punctured, with sparse semierect to erect pubescence; clypeal margin widely concave. Eyes medium-sized, their frontal distance 1.9 times eye diameter. Mandibles robust, curved, incisor margin with stout tooth in middle part. Labrum transverse, shiny; maxillary palpi slender, apical palpomere obliquely cut. Antennae serrate, relatively short, robust, reaching humeri ( Fig. 30 View FIGURES 22 – 33 ). Pronotum convex, transverse, widest at middle, 1.6 times wider than length at midline. Anterior margin almost straight, lateral margins convex, widened, slightly turned upward posteriorly; posterior margin bisinuate. Anterior angles inconspicuous, posterior angles obtuse ( Fig. View FIGURES 13 – 21

20); surface of disc covered with distinct deep punctures, with semierect pubescence, denser at angles. Scutellum flat, gradually narrowed, sparsely punctured; apex rounded. Prosternum transverse, wrinkled, frontal margin almost straight, prosternal process short, gradually declivitous. Mesoventrite v-shaped, anteromedially depressed. Elytra subparallel-sided, with longitudinal keel running from humeri toward apex, slightly wrinkled, finely punctured, sparsely 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. Aedeagus compact, with considerably curved phallus; paramera robust, slightly membranous apically; phallobase long, u-shaped ( Fig. 42 View FIGURES 34 – 45 ). Female and immature stages are unknown.

Variability. The pronotum of the holotype is more coarsely wrinkled and less distinctly punctured than in the paratypes.

Measurements. Holotype. BL 6.9 mm, EL 5.0 mm, WHe 1.4 mm, WHum 2.1 mm, PL 1.0 mm, PW 1.7 mm, Edist 0.9 mm, Ediam 0.5 mm. Paratypes. BL 6.5–7.0 mm, EL 4.8–5.2 mm, WHe 1.4–1.5 mm, WHum 2.1–2.2 mm, PL 1.1–1.2 mm, PW 1.7–1.8 mm, Edist 0.9 mm, Ediam 0.4–0.5 mm.

Distribution. Southern Turkey (Mersin prov.; Fig. 55 View FIGURE 55 ).

Etymology. The species name is a patronym proposed in honor of Mr. A. P. J. A. (Dré) Teunissen (Eindhoven, Netherlands).
