Wolski, Andrzej & Gorczyca, Jacek, 2012, Plant bugs of the tribe Bothriomirini (Hemiptera: Heteroptera: Miridae: Cylapinae) from the Oriental Region: descriptions of eight new species and keys to Oriental genera and species of Bothriomiris Kirkaldy, Dashymenia Poppius, and Dashymeniella Poppius, Zootaxa 3412, pp. 1-41 : 36

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) .

Distribution ( Fig. 87 ). Brunei (Temburong: Ulu ).

Type material. Holotype 3: BRUNEI: Ulu , Temburong ridge, M. C. Day, B. M., 1983-75 ( BMNH).
