Apogonalia anguSta Freytag, 2004

( Figs 1–5 )

Diagnosis. Anterior dorsum yellow with black marks. Crown ( Fig. 1 ) with four large irregular black spots on anterior margin and two between ocelli; some additional black marks on disc. Pronotum ( Fig. 1 ) with pair of anterolateral black maculae adjacent to eye, not attaining anterior margin; disc with two pairs of narrow longitudinal black stripes. Mesonotum ( Fig. 1 ) with pair of longitudinal black stripes on mesoscutum. Forewing ( Fig. 1 ) pinkish with narrow elongate black marks on veins; costal area anteriorly yellow; two transverse blackish stripes apically. Face yellow with black marks; frons medially with elongate, inverted V-shaped dark mark; pair of elongate, Y-shaped mediolateral black marks; lateral margins with black stripe. Clypeus with median black stripe dorsally bifurcated. Male pygofer broadly rounded. Paraphyses with pair of long divergent rami, slightly enlarged near pointed apex. Aedeagal shaft short, with pair of basiventral acute processes ( Freytag 2004, fig. 5). Female sternite VII ( Fig. 2 ) with conspicuous central black mark; posterior margin with small, median trapezoidal emargination. Sternite VIII ( Fig. 3 ) with semilunar sclerite, anteromedially produced into narrowly convex lobe.

Female length. 8.3 mm (n = 1).

Description of female genitalia. Sternite VII ( Fig. 2 ) moderately produced posteriorly; apical portion abruptly narrow; posterior margin with median, small trapezoidal emargination. Sternite VIII ( Fig. 3 ), in dorsal view, with semilunar sclerotized plate; anteromedian margin of plate with narrowly convex produced lobe; membranous portion with sclerotized areas anterolaterally to plate. Pygofer ( Fig. 4 ) moderately produced posteriorly; posterodorsal margin, in lateral view, almost rectilinear; posterior margin triangular; apex narrowly convex; disc with dorsal oblique row of long macrosetae extending from central portion to posterodorsal margin, posteroventral portion with long sparse macrosetae approximately on median third. Valvula I, in ventral view, with short and narrow process on basilateral margin, basal margin convex ( Fig. 5 ); blade, in lateral view (see Fig. 46 , A. histrio ), 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 (see Fig. 13 , A. blanchardi ), moderately broad beyond basal curvature, slightly narrowing gradually 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, triangular to trapezoidal and moderately prominent, with length about twice their high, spaced about 1.5 times 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: Azua, two males (holotype and paratype) ( CMNH) . Haiti: Ouest, one female ( BMNH) .
