Banyallarga yungensis Flint 1983:79 [Type locality: Argentina, Pcia. Tucumán, Horco Molle , near Tucumán; NMNH; male].

Ganonema vicarium — Martynov 1912:7 [description of male misidentified as Ganonema vicarium ].

A number of species in the subgenus Banyallarga have the apex of tergum X acute. The male of B. yungensis can be separated from those species by the high dorsal ridge of tergum X ( Fig. 14A ).

Adult. Forewing length 9.7–12.4 mm (n=64).

Head chestnut brown, with dorsomesal crest of golden setae. Maxillary palps dark brown. Antenna twice forewing length, dark brown, each flagellomere pale basally and with narrow patch of pale sensilla on anterior surface. Dorsal pterothorax chestnut brown; ventrolateral thorax and femora golden brown, tibiae covered with dark setae, each tarsomere dark basally and pale distally. Forewing mottled dark brown and gold, nygma marked by golden spot, proximal half of wing posterior mostly bright gold; thyridial cell filled with dark brown setae. Hind wing of male with basal semimembranous sleeve or pouch, enclosing brush of long setae.

Male. Tergum IX with faint anterior ridge, posterior margin indistinct ( Fig. 14B ); lateral ridge absent; dorsal pleural setae numerous, short; sternum IX with heavy anterior ridge. Preanal appendage subequal to tergum X, roundly tapered apically, with long setae on apical half. Tergum X in dorsal view tapered, with shallow rounded posteromesal notch, in lateral view with high dorsal ridge and tapered apically ( Fig. 14A ). Inferior appendage simple, with long setae ventrally and laterally on coxopodite; harpago rounded apically, of uniform circumference, with short fine setae basally and peglike setae apically. Phallus with phallotremal sclerite horseshoe­shaped, ventral sclerite a short tube, with large spiculate ventrolateral lobes and small rounded paired dorsomesal lobes ( Fig. 14D, E ).

Female. Sternum VIII anterior marginal ridge darkly sclerotized; fine setae covering surface of sternite. Tergum IX with anterior marginal ridge extending mesally length of segment; sternum IX with anterior and posterior lobes striate; smoothly sclerotized anteromesally and posterolaterally. Tergum X semimembranous, appendage roundly tapered posteromesally ( Fig. 15B ); sternum X with fine setae lateral to anal opening. Vaginal apparatus anterior and posterior sclerites equal in length; anterior sclerite emarginate anteriorly, posterolateral projections short; posterior sclerite ovoid ( Fig. 15A ).
