Diagnosis.

Spinolyprops cribricollis sp. n. shares with Spinolyprops lateralis the rough dorsal punctation of pronotum and elytra, the shape of the pronotum with lateral parts broadly separated from disc and bent up, the frons between eyes smaller than dorsal eye diameter, and the antennomeres 8-10 longer than broad. Both can be separated mainly by the anterior margin of the pronotum with feeble ( Spinolyprops cribricollis sp. n.) or deep excavation ( Spinolyprops lateralis ), and by different shape of the aedeagus (in Spinolyprops lateralis the apicale is pentagonal, compare Figs 20-21). Additionally, Spinolyprops lateralis is somewhat larger in the average (5.0-6.0 mm), and the elytra are slightly more rounded. Spinolyprops maculatus has a similar shape of the pronotum with feebly excavated anterior margin, but the aedeagus has the apicale of the aedeagus different triangular with straight sides. Spinolyprops trautneri has also a different aedeagus with broad pentagonal apicale (Fig. 24). See also the species key above.

Description.

Body length 4.5-5.0 mm. Dorsal and ventral surfaces and all appendages brown without metallic shine, head and pronotum slightly darker, elytra bicoloured with darker and lighter parts (see Fig. 2); dorsal surface roughly punctate, pun ctures 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 smaller than dorsal eye diameter, temples impunctate; maxillary palps with large securiform terminal palpomere; shape of antennomeres see Fig. 2, antennomere 3 not elongate, terminal three antennomeres not forming club. Pronotum widest in 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 not 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 triangular apicale with acute tip (Figs 14-15). No distinct external sexual dimorphism.

Remarks.

I hope not to fail in assigning the (so far disjunct) Chinese specimens from Yunnan and Guangxi to the same species. Shape and punctation of the pronotum, elytral colour and shape of aedeagus are not distinctly different from the specimens from Thailand. The type locality lies in a lowland habitat (Island Ko Chang), and the paratypes from Thailand were collected in higher altitudes (Doi Pui and Doi Inthanon). Obviously, this species has a wide ecological range.

Etymology.

The name refers to the rough punctation of the pronotum.
