Eurynassa tuberculicollis sp. nov.

(Figs. 8 G–H, 8 K–L, 17D)

Diagnosis. Male of E. tuberculicollis sp. nov. can

be separated from other species of Eurynassa by having very small granules distributed between sexually dimorphic punctures (Fig. 17D), especially visible on pronotum and ventral side of thorax, sometimes extending on the abdominal ventrites.

Description. Length 30–50 mm. Male. Body sub-parallel, head as long as wide; mandibles half of head length; pronotum 1.2× of head length and 1.8x of head width; elytra over 5× of head length. Antennal scape slightly longer than antennomere 3 length; interorbital width 1.2× of eye length. Prosternal process narrow, less than 0.5× width of procoxal cavity, and about half of hypomeron width; mesoventral process broader than prosternal process. Abdominal ventrites 1–5 about similar length, ventrite 5 emarginate at apex. Metatarsomeres 1–3 length ratio as 2:1:1, tarsomere 5 as long as tarsomere 1. Female. Pronotum weakly broader near posterior margin, dorsal surface only with sparse or dense regular punctures; elytra about 1.4× width of pronotum.

Etymology. The species name referring to the characteristic tiny granules present on areas with sexually dimorphic punctures.
