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.
