Taxonomic review of the fungal-inhabiting plant bug genera Bothriomiris and Dashymenia (Hemiptera: Heteroptera: Miridae: Cylapinae: Bothriomirini), with descriptions of two new species of Dashymenia from Thailand Author Wolski, Andrzej Author Yasunaga, Tomohide text Raffles Bulletin of Zoology 2016 2016-07-29 64 176 186 journal article 6622 10.5281/zenodo.4502022 c06ce14e-6438-463c-afc3-7a7ed39b2845 2345-7600 4502022 759928F1-E89E-412D-B49D-07236E25E648 Dashymenia gorczycai Wolski & Yasunaga , new species ( Figs. 5, 6 , 17–19 ) Diagnosis. Recognised by the following set of features: antennal segment II with indistinct brown patches; scutellum blackish; endosoma as presented below. Most similar to D. conspersa and D. gorczycai in sharing similar coloration of antennal segment II, with brown spots along entire length, and the similar shape of the endosomal MES. This new species can, however, be distinguished by the shape of endosomal sclerites. From D. conspersa it can be also distinguished by darker, dark yellow segment II ( Fig. 5 ), whereas D. conspersa has segment II contrastingly yellow ( Wolski & Gorczyca, 2012 : fig. 7). Description. Male. COLORATION ( Figs. 5, 6 ). Dorsum blackish to dark brown, with dirty yellow areas. Head . Dirty yellowish; antennal segment I mostly dirty yellowish, with paler, yellow one fourth and a narrow, brown annulation beyond base; segment II dark yellow with relatively large, blackish patches along entire length, apex with a narrow, blackish annulation; labium blackish yellow. Thorax . Pronotum . Blackish. Scutellum . Blackish, with a weakly paler, dark brown apex. Thoracic pleura . Blackish; evaporative areas fuscous; peritreme dark brown; hemelytron dark brown with a contrastingly yellow patch on apical portion of endocorium and inner angle of cuneus; membrane fuscous. STRUCTURE, TEXTURE, AND VESTITURE ( Figs. 5, 6 ). Body elongate oval; dorsum covered with long, semirecumbent setae. Head . Covered with long, erect and semirecumbent setae, weakly rugose; antennal segment I gradually becoming wider toward apex, covered with relatively sparse, almost recumbent setae, except for glabrous basal one fourth; segment II weakly broadened toward apex, covered with dense, semirecumbent setae and with a few stiff, protruding, bristle–like setae. Thorax . Pronotum . Calli indistinct. Scutellum . Entirely punctate, moderately arched. Hemelytron . Membrane with a major cell rectangular, minor cell triangular. Male genitalia . Aedeagus ( Fig. 17 ). Endosoma strongly membranous; DSS long, reaching apex of endosoma, nearly cylindrical, strongly sinuate along entire length; MES situated apicolaterally, relatively small, shorter than half of endosoma, nearly rounded on basal two thirds, strongly tapering, pointed on apical one third; PES relatively large, occupying more than basal half of endosoma, relatively broad and stout, right lateral margin arcuate, left lateral margin somewhat sinuate, with a relatively large, pointed process subapically, apex of PES serrate, except for smooth extreme apex, strongly tapering and pointed. Left paramere ( Fig. 18 ). Apical process only slightly arcuate, weakly narrowed apically; paramere body relatively thin, not strongly thicker than apical process; sensory lobe convex. Right paramere ( Fig. 19 ). Apical half bottle-shaped, basal half nearly cylindrical, weakly narrowed basally. Measurements . Body . Length 5.6, width 2.5. Head . Length 0.73, width 1.4, interocular distance 0.7. Antenna . Length of segment I 0.55, II 1.78, III and IV missing in the examined specimen. Labium . Length of segment I 0.55, II 0.6, III 0.32, IV 0.35. Pronotum . Length 1.55, width of anterior margin 1.05, length of lateral margin 1.4, width of posterior margin 2.4. Etymology.
