Dashymeniella ulu Wolski & Gorczyca sp. nov.

(Figures 16, 53, 87, 88–93, 105–107)

Diagnosis. Dashymeniella ulu can be recognized by the following set of features: dorsal surface pale brown (Fig. 16); head punctate; DSS with the apical, widened portion short; AES and PES lacking; MES relatively small, somewhat curved (Fig. 105).

Most similar to D. spatulatiformis and D. viklundi in sharing the characters presented in the diagnosis of D. spatulatiformis . The new species differs, however, by the paler dorsal coloration, and by the shape of the endosomal sclerites.

Description. Male. COLORATION (Fig. 16). Dorsal surface brown, with paler, dull yellowish areas. Head. Brown; antennae dull yellowish; segment I tinged with red apically; labium brown. Thorax. Pronotum. Entirely brown. Thoracic pleura. Brown, darker in coloration than pronotum; evaporative areas creamy, weakly tinged with red. Hemelytron. Brown basally, remainder of hemelytron dull yellowish brown; membrane pale gray. Legs. Coxae, pro- and mesofemora brownish, tinged with dull yellow; mesotibia dull yellowish, with pale yellow annulation apically; mesotarsus pale yellow; remaining segments broken. STRUCTURE AND VESTITURE (Figures 16, 53, 88–93). Suboval; dorsal surface strongly shining, glabrous. Head. Shining, glabrous; vertex and frons with sparse, deep punctation; frons somewhat rugose near apical swelling; antennal segment I covered with very sparse, fine setae, narrowed basally, apical half almost cylindrical; segment II shining, gradually becoming thicker apically, covered with moderately dense, thick, rather long, semirecumbent setae; labium stout, apex reaching just beyond metacoxae. Thorax. Pronotum. Covered with moderately dense punctures; calli flattened, inpunctate; anterior margin separated from remainder of pronotum. Scutellum. Flattened, covered with relatively sparse punctation. Hemelytron. Moderately densely punctate. Legs. Short; coxae and mesofemur covered with sparse setae; mesotibia shining, covered with sparse setae basally, remainder of tibiae more matte, covered with dense, semirecumbent setae.

Male genitalia. Endosoma (Fig. 105). Strongly membranous at basal half; DSS stout with apical surface widened, short; MES relatively small, somewhat curved. Left paramere (Fig. 100). Apical process weakly pointed; sensory lobe weakly convex. Right paramere (Fig. 107). Weakly curved; apical process sharply pointed.

Measurements. 3: body length 3.1, width 1.45. Head. Length 0.33, width 0.88, diameter of eye in dorsal view 0.21. Antenna. Length of segment I 0.46, II 0.83, III, 0.44, IV 0.87. Labium. Obscured by glue and immeasurable. Pronotum. Length 0.83, width of anterior margin 0.71, lateral margin length 0.72; width of posterior margin 1.4.

Female. Unknown.

Etymology. The specific epithet refers to the type locality, Ulu (Brunei) .
