Dere telnovi sp. nov.

( Figs. 1-2 )

Type material. HOLOTYPUS, male: Philippines / Palawan isl., Roxas , 05. 2020 / local collector leg. [printed white label] . HOLOTYPUS: / Dere / telnovi sp. nov. / A.Barševskis, D. Saulīte descr. 2020 [red handwritten label] ( DUBC) .

PARATYPUS, 9 specimens (6 males, 3 females). All paratypes are from the same locality and with same data as that in holotype, and were collected in the period from 05.2020 to 09.2020. All paratypes with additional red handwrited label: “ PARATYPUS: / Dere / telnovi sp. nov. / A.Barševskis, D. Saulīte descr. 2020” .

General distribution: Palawan Isl., Philippines.

Description. Body black, some specimens particularly dark-brown, with yellow-red pronotum. Body elongated, narrow, elytra flattened, with coarse, dense punctation and wrinkles. Length: 7.7-9.9 mm, maximal width: 1.6- 2.4 mm; length/width ratio: 4.1-4.8.

Head flattened, with square frontal portion, and convex, bilobate eyes. Dorsal surface of head with coarse punctation. Head with short impressed longitudinal line between thick and extended antennal bases, from medioapical portion behind clypeus obliquely stretching basally, forming small and thin, raised stripe. Labrum dark-brown, slightly pubescent, shiny, with some short transverse impressed lines. Clypeus dar k-br own, tr an sver se, sh in y. Mandibles dark-brown, very sharp, massive, wide, shiny, relatively short, with sparse, short pubescence on lateral portion. Cheeks with sparse, short, dark pubescence. Antennae slender. Male antennae shorter than body, almost reaching apex of elytra. Female antennae shorter, reaching slightly behind middle portion of elytra. Antennae covered with coarse punctures and fine, sparse pubescence; antennomeres 1– 5 thickened apically, black.

Pronotum yellow-red, uneven, cylindrical, elongated, neck-shaped narrowed in apical and basal portions. Surface with very dense and coarse punctation and short wrinkles.

Scutellum small, with slightly rounded apex. Pars stridens almost completely covered with pronotum.

Elytra almost parallel-sided, dark-brown, black, or dark-brown with indistinct yellow-brown portion around suture behind scutellum. Elytra from middle slightly widened apically, flattened, with indistinctly raised shoulders hump. Elytra slightly shiny, with indistinct metallic reflection. Punctation of elytra very dense, not arranged in longitudinal rows. Apical margin of elytra with two sharp extensions: smaller on apical edge near suture and longer, latero-apical extension.

Ventral surface of body with dense, grey pubescence. Legs black, with very fine pubescence, inner margin of tibia with dense golden pubescence.

Differential diagnosis. Based on the shape of the body, D. telnovi sp. n. is similar to D. coloripennis Vives, 2015 , but can be distinguished by different coloration of the elytra and legs. Elytra of new species unicolour, dark brown to black or dark-brown with yellow-brown misty portion around suture behind scutellum, and legs generally black, while elytra of D. coloripennis with a well-defined longitudinal yellow spot with expanded apical part and legs (except forelegs) are bicolor: basal portion of femur is yellow.

Etymology. This species is named after my colleague Dr. Dmitry Telnov (Riga, Latvia) in appreciation of cooperation, and in gratitude for his contribution to the studies of Coleoptera of the world.
