Dashymeniella spatulatiformis Wolski & Gorczyca sp. nov.

(Figures 13–14, 52, 87, 94–95, 96–98)

Diagnosis. Dashymeniella spatulatiformis can be recognized by the following set of features: dorsal surface varying from brown to dark brown, nearly black (Figs. 13–14); head somewhat rugose; endosoma with DSS spoonlike; PES stout, longer than other endosomal sclerites, gradually becoming narrower towards apex (Fig. 96).

D. spatulatiformis is most similar to D. ulu and D. viklundi in sharing the following set of characters: dorsal surface glabrous (Figs. 13–14, 16–17); pronotum with the anterior margin separated from the remainder of the pronotum by relatively deep, transverse incision; posterior lobe of the pronotum without any swelling medially (Figs. 13–14, 16–17); pronotal calli flattened or weakly raised (Figs. 13–14, 16–17); DSS stout and large, occupying most of the endosoma, distinctly broadened apically; AES distinctly smaller than the DSS and not embracing the latter. D. spatulatiformis differs, however, by having the rugose frons, the pronotal calli weakly raised, and by the differing shape of the endosomal sclerites (Figs. 96, 102, 105); right paramere with the apical process narrower than remainder of the paramere (Figs. 98, 104, 107).

Description. Male. COLORATION (Figs. 13–14). Dorsum varying from brown to dark brown. Head. Dark brown; vertex, maxillary and mandibular plates, and inner portion of gula somewhat paler than remainder of head; antennae dull yellowish; labium varying from dull yellowish with brown areas to reddish brown. Thorax. Thoracic pleura. Dark brown. Legs. Coxae brown; femora brown, dull yellowish apically; pro- and mesotibia brownish, with paler dull yellowish apex; metatibia brown, with pale yellow annulation apically; tarsi dull yellowish.

STRUCTURE AND VESTITURE (Figs. 13–14, 52, 94–95). Suboval, dorsal surface strongly shining, glabrous. Head. Strongly shining, glabrous; vertex and frons with sparse, deep punctation; frons strongly rugose; antennal segment I covered with very sparse, fine setae, narrowed basally, apical half nearly cylindrical; segment II gradually thickened towards apex, with strongly shining basal portion, covered with moderately dense, long, semirecumbent setae; apex of labium reaching metacoxae. Thorax. Pronotum. Punctation moderately dense; calli weakly raised, inpunctate; anterior margin separated from remainder of pronotum by relatively deep, transverse incision. Scutellum. With moderately dense punctation and longitudinal, weakly raised elevation. Hemelytron. Covered with moderately dense punctation. Legs. Short; coxae, femora, and bases of tibiae covered with sparse setae; tibiae basally shining, apically matte, covered with dense, semirecumbent setae.

Male genitalia. Endosoma (Fig. 96). DSS with broadened, rounded, spoon shaped apical portion; AES gradually becoming thinner towards apex; MES stout, large, hook-shaped; PES largest, stout, gradually becoming thinner toward apex. Left paramere (Fig. 97). Rounded; apical process somewhat sharply pointed apically. Right paramere (Fig. 98). Body nearly parallel-sided; apical process strongly narrower than remainder of paramere, sharpened apically.

Female. Similar to male in coloration, structure, and vestiture but somewhat larger in size.

Measurements. Ƥ / 3 (n=3, holotype measurements in parentheses): body length 3.9/3.6–3.7 (3.7), width 2.0/ 1.75–1.77 (1.77); length of head 0.41/0.34–0.37 (0.34), width 1.1/0.95–0.97 (0.95), diameter of eye in dorsal view 0.25/0.22–0.25 (0.22); length of antennal segment I 0.44/0.45–0.46 (0.45), II 1.1/0.95–0.97 (0.97), III (3) 0.55, IV (3) 0.9. Labium. Length segment (3, immeasurable in Ƥ) I 0.46–0.5 (0.5), II 0.45–0.5 (0.5), III 0.3–0.36 (0.3), IV 0.28–0.3 (0.3). Pronotum. Length 1.16/0.97 (0.97), width of anterior margin 0.78/0.78–0.8 (0.8), lateral margin 1.0/ 0.78–0.81 (0.78), width of posterior margin 1.84/1.62–1.65 (1.65).

Etymology. The specific epithet is derived from the Latin “spatula,” (spoon) and “forma,” (shape) and is used to denote the spoon shaped endosomal sclerite DSS.
