Xiphocentron (Antillotrichia) maiteae new species

Fig. 3 View FIGURE 3 A–G

Diagnosis. The new species is very different from all previously described species. It is differentiated by the structure of each inferior appendage, which has a basoventral margin strongly produced posterad with sclerotized indentations on the medial margin.

Description. Male adult. Length of each forewing 3.2–3.5 mm (n= 5). Overall color (in alcohol) nearly uniformly medium brown, forewings covered with uniformly fine brown setae; forewings with forks 2 and 4; hind wings each with only fork 2 ( Fig. 3 View FIGURE 3 B). Apical spur of each hind tibia not modified ( Fig. 3 View FIGURE 3 A). Segment V bearing pair of anteroventral glands without external glandular processes.

Male genitalia. Tergum IX, in lateral view ( Fig. 3 View FIGURE 3 E), rounded; base and apex subequal in height; anterior margin rounded, posterior margin straight with dorsal end projecting dorsoposterad; in dorsal view ( Fig. 3 View FIGURE 3 C), trapezoidal, wide basally, narrower apically; anterior margin with deep, U-shaped, mesal emargination; apical margin mesally projecting. Sternum IX oval, in lateral view ( Fig. 3 View FIGURE 3 E); short, less than twice as tall as long; anterior margin with short, rounded, anteromesal projection bearing long, slender, pointed anterior flange; ventral margin rounded; dorsal margin rounded; in ventral view ( Fig. 3 View FIGURE 3 D), rounded, anterior margin straight with lateral projections; posterior margin rounded with shallow mesal emargination. Segment X semimembranous; in lateral view ( Fig. 3 View FIGURE 3 E), oblong, rounded apically, projecting apicoventrally; in dorsal view ( Fig. 3 View FIGURE 3 C), subtriangular, wider basally, narrower and divided apically into two apicolateral lobes with small setae on apicomesal margins; in ventral view ( Fig. 3 View FIGURE 3 D) with deltoid projection. Preanal appendages long, surfaces heavily setose; in lateral view ( Fig. 3 View FIGURE 3 E), each nearly parallel-sided, basally directed posterodorsad then near middle angled approximately 120º posterad, apex slightly enlarged; in dorsal view ( Fig. 3 View FIGURE 3 C), narrowest basally, slightly enlarged apically. Inferior appendages long, approximately as long as preanal appendages, heavily setose basally; in lateral view ( Fig. 3 View FIGURE 3 E), each wide basally, basoventral margin strongly and broadly produced posterad, posterodorsally, slender with clavate apex; in ventral view ( Fig. 3 View FIGURE 3 D), lateral margin rounded, internal margin sclerotized and dentate; in dorsal view, divergent basally, each with dorsomesal margin abruptly and deeply emarginate. Aedeagus long, slender, compressed, apex very enlarged, 5 times as broad as base in dorsal view ( Fig. 3 View FIGURE 3 G), twice as broad as base in lateral view ( Fig. 3 View FIGURE 3 F).

Etymology. Named in memoriam of the Biologist Maria Theresa Sopena Stradmann (1968–2013) for her effort within the “Environmentalist Group of Bahia” (GAMBA) for the preservation of the Serra da Jibóia Mountains, where type specimens were collected. She preferred to be called by her nickname, “Maite.”

Distribution. Brazil (BA).
