Canoptila bifida Mosely View in CoL

( Figs. 1–3 View FIGURE 1 View FIGURE 2 View FIGURE 3 )

Canoptila bifida Mosely, 1939: 218 View in CoL [Type locality: Brazil, Santa Catarina, Nova Teutônia; BMNH; male].

Canoptila bifida View in CoL can be distinguished from C. williami , new species, by the shape of abdominal segment IX, which is much broader laterally. Tergum X is triangular in lateral view in C. bifida View in CoL and quadrate in C. williami . In C. bifida View in CoL , tergum X is also bifid in dorsal view, while it is subquadrate in the new species. The dorsomesal processes on the endotheca are much more heavily sclerotized and prominent in C. bifida View in CoL than in C. williami , while the basolateral digitate parameres are smaller. In the forewing of C. bifida View in CoL , the apical part of Cu2 turns sharply downward to meet the wing margin at the intersection of Cu1 and Cu2, whereas in C. williami , it turns down distad of this intersection.

Adult male. Length of forewing: 2.7–3.0 mm (n =4). Body, wings, and appendages tawny, legs and base of antennae yellowish brown. Wings ( Figs. 2 View FIGURE 2 A, 2B) as detailed in the generic diagnosis.

Male genitalia ( Fig. 3 View FIGURE 3 ). Sternum VI ( Fig. 3 View FIGURE 3 A) with thin, digitate mesal process, projecting caudally. Abdominal segment IX ( Fig. 3 View FIGURE 3 B) broadest laterally, anterior margin sinuous. Tergum IX in lateral view ( Fig. 3 View FIGURE 3 B), with anterior margin sinuous, forming truncate ridge apicodorsally; in dorsal view ( Fig. 3 View FIGURE 3 C), with posterior margin rounded, covered in fine microtrichia. Tergum X in lateral view ( Fig. 3 View FIGURE 3 B), triangular, ventral margin smooth, sloping downward, setose dorsally, apically, and ventrally, apex rounded; in dorsal view ( Fig. 3 View FIGURE 3 C), bifid, lightly sclerotized laterally, membranous mesally, with pair of long spinelike processes arising from posterolateral margin at right angle, curved inward. Phallocrypt ( Fig. 3 View FIGURE 3 B) extending from beneath tergum X to ventral region of segment IX, entirely membranous except for lightly sclerotized phallic shield where phallic apparatus is attached. Phallobase ( Figs. 3 View FIGURE 3 B, 3D) reduced, lightly sclerotized, with paired row of setae ventrolaterally. Endotheca ( Figs. 3 View FIGURE 3 B, 3D) membranous, basoventrally bearing pair of small, membranous digitate parameres with small apical sclerite. Endophallus ( Figs. 3 View FIGURE 3 B, 3D) highly membranous, enlarged and convoluted when evaginated; dorsomesally bearing pair of large, heavily sclerotized, bifid processes, their Material examined: BRAZIL: Santa Catarina: Seara (Nova Teutônia), 27°11'00"S, 052°23'00"W, 300–500 m, 1.xii.1937, Plaumann— 1 male (holotype) (UMSP000107591) (BMNH); same except 1.i.1963, Plaumann— 2 males (NMNH); same except 1.x.1964, Plaumann— 1 male (NMNH).
