Kobieluszova, Lucie & Kundrata, Robin, 2015, Taxonomic review of Drilus Olivier, 1790 (Elateridae: Agrypninae: Drilini) from Asia Minor, with descriptions of seven new species and comments on the female antennal morphology in Drilini, Zootaxa 4012 (1) : -

Drilus badius sp. nov.

( Figs 2 , 13 , 22 , 34 )

Type material. Holotype, male, " Turcia, coll. E. Friv., Friv., 3945, Drylus fulvicollis Kiesw., coll. E. Frivaldszky" ( HNHM).

Type locality. Turkey (with no additional data).

Diagnosis. Drilus badius sp. nov. is similar to D. obscuricornis Pic, 1899 , but differs in the lighter body coloration and larger, more distinct pronotal punctation ( Figs 2, 6 ).

Description. Male (holotype). Body 3.0 times longer than width at humeri, reddish brown, scape, pedicel, tibiae and tarsi yellowish, antennomeres 3–11 light brown; body covered with yellowish pubescence ( Fig. 2 ). Head including eyes about as wide as anterior margin of pronotum ( Fig. 13 ), dorsally with small shallow depression, rather smooth, sparsely and finely punctured, with sparse semierect pubescence; clypeal margin widely concave. Eyes medium-sized, their frontal distance 2.0 times eye diameter. Mandibles curved, incisor margin with short conspicuous tooth in middle part. Labrum transverse; maxillary palpi slender, apical palpomere obliquely cut. Antennae pectinate, reaching one third of elytral length; antennomere 3 long, serrate, antennomeres 4–10 pectinate, apical antennomere simple, longest ( Fig. 22 ). Pronotum slightly convex, transverse, widest at middle, 1.7 times wider than length at midline. Anterior margin widely emarginated medially, lateral margins convex, widened; posterior margin convex, bisinuate. Anterior angles inconspicuous, posterior angles distinct, obtuse ( Fig. 13 ); surface of disc rather smooth, sparsely covered with fine punctures, with sparse pubescence, mainly at angles. Scutellum gradually narrowed, rather smooth; apex rounded. Prosternum transverse, with transverse widely vshaped wrinkles, with distinct transverse groove near frontal margin; frontal margin almost straight; posterior margin widely convex, steeply declivitous, prosternal process inconspicuous. Mesoventrite v-shaped, depressed anteromedially. Elytra subparallel-sided, covered with semierect pubescence, sparser basally, denser apically. 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 with stout, considerably curved phallus; paramera long, slightly membranous apically; phallobase u-shaped ( Fig. 34 ). Female and immature stages unknown.

Measurements. BL 5.2 mm, EL 4.0 mm, WHe 1.2 mm, WHum 1.9 mm, PL 0.9 mm, PW 1.6 mm, Edist 0.8 mm, Ediam 0.4 mm.

Distribution. Turkey (no additional data known).

Etymology. The specific epithet badius is the Latin adjective referring to the general body coloration.
