Figs. 31–32 View FIGURE 31 View FIGURE 32

Banyallarga sanchezi is easily distinguished from all other species in the genus by the highly modified tergum X and the mesoventral process of the inferior appendage ( Fig. 31A View FIGURE 31 ). Tergum X has two pairs of long digitate ventrolateral processes. In addition, this is the only species in the genus that bears a long digitate mesal process on the coxopodite. The species is known only from a single male specimen.

Adult. Forewing length 11.3 mm (n=1).

Head golden brown. Maxillary palps golden brown. Antenna chestnut brown, each flagellomere pale basally. Dorsal pterothorax golden brown; ventrolateral thorax and legs golden brown, metathoracic tibia of male with long posterior setal fringe. Forewing mottled gold and golden brown. Hind wing of male with basal semimembranous sleeve or pouch, enclosing brush of long setae.

Male. Sternum VII with pointed anteromesal process. Tergum IX with anterior margin deeply emarginate; sternum IX strongly angularly projected posteriorly; pleural setae numerous ( Fig. 31B View FIGURE 31 ). Preanal appendage shorter than tergum X, narrow, apex slightly flexible, covered with long fine setae. Segment X with short spinelike setae along posterior midline; with two pairs of long digitate ventrolateral processes ( Fig. 31B View FIGURE 31 ) Inferior appendage with long setae ventrally and laterally on coxopodite, base of coxopodite with long digitate mesal process; harpago of uniform diameter along length, with fine setae basally and peglike setae apically ( Fig. 31B View FIGURE 31 ). Phallus with U­shaped phallotremal sclerite, thornlike setae on endothecal membrane ( Fig. 31D View FIGURE 31 ).

Female. Unknown.
