Figs. 27–28 View FIGURE 27 View FIGURE 28

Banyallarga nica is similar to B. echinata in having prominent spinelike setae on tergum X; however, in B. nica these spines are shorter and restricted to the apices of the posterior processes ( Fig. 27A, B View FIGURE 27 ). All specimens I examined were preserved in ethanol; consequently, color and wing pattern were not preserved.

Adult. Forewing length 10.0– 10.8 mm (n=14).

Antenna twice forewing length. Hind wing of male with basal semimembranous sleeve or pouch, enclosing brush of long setae.

Male. Lateral margin of sternum IV deeply excavated (as in Fig. 16 View FIGURE 16 ). Sternum VII with pointed anteromesal process. Tergum IX with mesal ridge extending to posterior margin, covered dorsally by semisclerotized membrane bearing dense fine pilosity ( Fig. 27B View FIGURE 27 ); lateral ridge present; dorsal pleural setae fine and numerous ( Fig. 27A View FIGURE 27 ). Preanal appendages long, slightly expanded and flexible apically; apical 2/3 covered with long fine setae ( Fig. 27A, B View FIGURE 27 ). Segment X deeply emarginate posteriorly, forming two digitate lateral projections, apices of projections bearing short spinelike setae ( Fig. 27B View FIGURE 27 ). Inferior appendage simple, with long setae ventrally and laterally on coxopodite; harpago of uniform diameter along length, with fine setae basally and peglike setae apically ( Fig. 27C View FIGURE 27 ). Phallus with horseshoe­shaped phallotremal sclerite, thornlike setae proximally and ventrally on endothecal membrane ( Fig. 27D View FIGURE 27 ).

Female. Sternum VII with pointed anteromesal process. Sternum VIII anterior marginal ridge darkly sclerotized; fine setae covering posterior surface of sternite ( Fig. 28C View FIGURE 28 ). Tergum IX without mesal ridge, posterior margin indistinct from tergum X ( Fig. 28B View FIGURE 28 ); sternum IX with anterior and posterior lobes darkly sclerotized and striate, smoothly sclerotized anteromesally, punctate posterolaterally ( Fig. 28A View FIGURE 28 ). Tergum X semimembranous, appendage roundly tapered ( Fig. 28B View FIGURE 28 ); sternum X with semisclerotized plates bearing fine setae lateral to anal opening ( Fig. 28A View FIGURE 28 ). Vaginal apparatus anterior sclerite truncate anteriorly, posterolateral projections acute; posterior sclerite enclosed within a semisclerotized sheath half width of posterior abdomen; dorsal connective membrane with regular pleating ( Fig. 28A View FIGURE 28 ).
