Apogonalia loxa Freytag, 2004

( Fig. 61 )

Diagnosis. Anterior dorsum ( Fig. 61 ) yellow with black marks. Crown ( Fig. 61 ) pale yellow with six black maculae, two pairs on anterior margin and one pair between ocelli; pair of anteromedian, diagonal black arches; small black maculae between eye and ocellus and posterior to eye. Pronotum ( Fig. 61 ) with anterior third pale yellow and posterior two-thirds greenish-yellow; pair of broad black maculae posterior to eyes; small elongate black maculae on median portion. Mesonotum ( Fig. 61 ) pale yellow with pair of elongate, anterior black maculae connected to each other on transverse sulcus. Forewing ( Fig. 61 ) brown with costal area greenish-yellow and dark brown stripes on veins; corium with three broad transverse white to yellow stripes bordered by dark brown. Face pale yellow with pair of longitudinal black stripes on frons, converging to median stripe on clypeus; lateral portion of frons with black area; gena pale yellow with black, vertical narrow stripe near posterior margin. Male pygofer with inner ventroapical spiniform process, medially directed. Paraphyses with V-shaped basal plate and apical pair of long and moderately narrow rami. Aedeagal shaft with pair of basilateral hook-shaped processes, posteriorly directed, and pair of similar processes on basiventral portion, anteriorly directed. Female sternite VII with conspicuous central black macula; posterior margin with median, deep trapezoidal emargination. Sternite VIII with semilunar sclerotized plate slightly produced anteromedially.

Female length. 8.5 mm (n = 1).

Description of female genitalia. Sternite VII moderately produced posteriorly; apical portion gradually narrowed; posterior margin with median, deep trapezoidal emargination. Sternite VIII, in dorsal view, with semilunar sclerotized plate; anteromedian margin of plate slightly produced. Pygofer moderately produced posteriorly; apex convex in lateral view; some macrosetae distributed on apical half of ventral portion and on subapical portion. Valvula I, in ventral view, with short and narrow process on basilateral margin, basal margin truncate; blade, in lateral view, elongate and narrow, apical half slightly broad, apex acute; dorsal sculptured area extending along almost entire length of blade; processes linear, forming approximately parallel rows, oblique to blade axis; ventral sculptured area on subapical and apical portions; processes scale-like, distally arranged in approximately parallel and oblique rows. Valvula II, in lateral view, moderately broad beyond basal curvature, gradually narrowing towards acute apex; blade with about 20 teeth distributed from beginning of expanded portion to apex, closer to one another distally; teeth, on median portion, trapezoidal and moderately prominent, about 1.5 times longer than high, spaced from one another about twice tooth length; preapical prominence distinct, approximately aligned to anteapical tooth; denticles distributed on all dorsal margin of shaft and from preapical prominence to apex on ventral margin.

Material examined. Dominican Republic: Pedernales, one male and one female (holotype and paratype, respectively) ( CMNH).
