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 : 36-39

Dashymeniella viklundi Wolski & Gorczyca sp. nov.

( Figs. 17 , 46 , 87 , 102 – 104)

Diagnosis. Dashymeniella viklundi is recognized by the following set of features: dorsum nearly black ( Fig. 19 ); head covered with sparse punctures ( Fig. 46 ); DSS large, stout, with apical widened portion nearly triangular; AES relatively small, narrowed basally and apically; MES stout, large, hook-shaped; PES lacking ( Fig. 102 ); right paramere with apical process moderately narrowed ( Fig. 104 ).

Most similar to D. spatulatiformis and D. ulu in sharing the characters presented in the diagnosis of D. spatulatiformis . The new species can, however, be distinguished by the coloration of dorsum, and the shape of the male endosomal sclerites.

Description. Male. COLORATION ( Fig. 17 ). Entire dorsal surface nearly black. Head. Dark brown, paler than remainder of body; antenna dull yellowish; labium dark brown; segments III and IV darker than I and II. Thorax. Thoracic pleura. Nearly black. Legs. Coxae dark brown; metafemur dark brown, paler than coxae; metatibia almost entirely brownish, except for pale, yellowish annulation apically; metatarsus dull yellowish; remaining legs broken. Abdomen. Dark brown. STRUCTURE AND VESTITURE ( Fig. 17 , 46 ). Suboval, dorsum strongly shining, glabrous. Head. Strongly shining, glabrous; vertex and frons with sparse and relatively deep punctuation; vertex with weakly raised tubercles each contiguous with occipital carina; antennal segment I narrowed basally, cylindrical at apical half, sparsely covered with fine, semirecumbent setae; segment II mixed with moderately dense, long, semirecumbent, thick setae and with small, scale-like, recumbent setae, narrowed at apical one fifth, remainder of segment II nearly cylindrical; labium stout, apex reaching just beyond metacoxae. Thorax. Pronotum. Punctation moderately dense; anterior margin separated from remainder of pronotum; calli flattened, inpunctate. Scutellum. With moderately raised, inpunctate elevation apically. Hemelytron. Punctation similar to that of pronotum.

Male genitalia. Endosoma ( Fig. 102 ). DSS large, stout, with apical widened portion nearly triangular; AES relatively small, narrowed basally and apically; MES stout, large, hook-shaped. Left paramere ( Fig. 103 ). Rounded; apical process somewhat pointed; sensory lobe weakly convex. Right paramere ( Fig. 104 ). Sinuate laterally; apical process narrowed apically.

Measurements. 3 (n= 2, holotype measurements in parentheses): Body length 3.2–3.3 ( 3.2), width 1.4–1.7 ( 1.4). Head. Length 0.36–0.42 ( 0.36), width 0.86–0.9 ( 0.86), diameter of eye in dorsal view 0.22–0.23 ( 0.22). Antenna. Length of segment I 0.44–0.5 ( 0.44), II 0.79–0.98 ( 0.79), III 0.46–0.55 ( 0.46), IV 0.78 ( 0.78). Labium. Length of segment I 0.5 ( 0.50), II 0.46 ( 0.46), III 0.34 ( 0.34), IV 0.55 ( 0.55). Pronotum. Length 0.84–0.95 ( 0.84), width of anterior margin 0.7–0.75 ( 0.7), length of lateral margin 0.68–0.75 ( 0.68), width of posterior margin 1.38–1.56 ( 1.38).

Female. Unknown.

Etymology. The specific name is dedicated to Bert Viklund ( NHRS) who was one of the collectors of this species.
