Diagnosis
Spinolyprops thailandicus sp. n. is characterized by the shape of the pronotum with deeply excavated anterior margin and with the lateral parts broadly separated from disc and bent up, in combination with rough dorsal punctation of pronotum and elytra and the frons between eyes smaller than dorsal eye diameter. The aedeagus of Spinolyprops thailandicus sp. n. is similar as in Spinolyprops cribricollis sp. n.(compare Figs 14–15), but in this species the lateral parts of the pronotum are not so widely separated from the disc as in Spinolyprops thailandicus sp. n., and the anterior margin of the pronotum is only feebly excavated. See also species key above.
Description
Body length 4.3–5.3 mm. Dorsal and ventral surfaces and all appendages brown without metallic shine, elytra bicoloured with darker and lighter parts in different variation (Figs 10–12); dorsal surface roughly punctate, punctures with long erect setae, surface between punctures shining. Head with punctation similar as on pronotum; genae distinctly swollen, clypeal suture somewhat indistinct by rough punctation, clypeus with punctation as on frons, anterior margin of clypeus straight; eyes reniform, frons between eyes as broad as dorsal eye diameter, temples impunctate; maxillary palps with large securiform terminal palpomere; shape of antennomeres see Figs 10–12, antennomere 3 not elongate, terminal three antennomeres not forming club. Pronotum widest slightly before middle, anterior and posterior margins unbordered, lateral margins unbordered but distinctly crenulate, anterior corner rounded, posterior corners acute, surface flat with irregular rough and partly confluent punctation, lateral parts broadly separated from disc and bent up; propleura with sparser and smaller punctation and shorter setation as on pronotum, prosternal process slightly prominent; metaventrite with punctation as on propleura. Scutellum visible, shining, without punctation. Hind wings present. Elytra elongate oval, widest in middle, lateral margin distinctly dentate in humeral region, margin completely visible from above; surface with rough punctation as on pronotum, but not confluent, punctation irregular and not arranged in rows or striae; epipleura with sparser and smaller punctation as on elytral disc, similar as on propleura. Ventrites with fine and widely separate punctation, terminal ventrite unbordered, intersegmental membranes exposed between ventrites 3–5. Legs without particular modifications, tibiae without external keels, tibial spurs short. Aedeagus with broad spade-like apicale with rounded tip (Fig. 25). No distinct external sexual dimorphism.
Etymology
Named after the type locality in Thailand.
