Apogonalia hiStrio (Fabricius, 1794)

( Figs 40–47 )

Diagnosis. Anterior dorsum yellow with dark brown marks; two pairs of narrow, irregular longitudinal dark brown stripes on mediolateral portions, usually discontinuous. Pronotum with pair of anterolateral dark brown maculae adjacent to eyes ( Figs 40, 41 ); disc rarely with pair of broad longitudinal orange stripes between dark brown stripes ( Fig. 41 ). Mesonotum ( Figs 40, 41 ) rarely with pair of longitudinal orange stripes ( Fig. 41 ). Forewing pink with brown veins ( Fig. 40 ) or with dark brown stripes on veins ( Fig. 41 ); clavus with two yellow stripes ( Fig. 40 ) or with broad orange stripe ( Fig. 41 ) adjacent to claval sulcus; costal area with anterior portion yellow or with broad longitudinal orange stripe, bordered internally and externally by brown stripes; apex of discal cells with or without large dark brown mark, subtriangular ( Fig. 40 ) or roundish ( Fig. 41 ); apical portion with two transverse dark stripes. Face ( Fig. 42 ) yellow with dark brown marks; frons with pair of elongate V- or Y-shaped mediolateral dark brown marks; lateral margins with dark brown stripe. Clypeus with median brown stripe, dorsally bifurcated or not.

Male pygofer without processes. Paraphyses symmetrical, with U-shaped basal plate and pair of long, moderately narrow rami. Aedeagal shaft with pair of triangular lateral basimedian processes, posteriorly directed, and hookshaped basiventral paired processes, anteriorly directed. Female sternite VII ( Fig. 43 ) with conspicuous central dark brown macula; posteromedian margin deeply concave. Sternite VIII ( Fig. 44 ) with semilunar sclerotized plate, anteriorly bilobate and deeply notched medially.

Female length. 6.3–8.0 mm (n = 6).

Description of female genitalia. Sternite VII ( Fig. 43 ) moderately produced posteriorly; apical portion abruptly narrowed; posterior margin with deep median concavity. Sternite VIII ( Fig. 44 ), in dorsal view, with semilunar sclerotized plate, anteriorly bilobate, with deep, narrow median notch. Pygofer ( Fig. 45 ) slightly produced posteriorly; posterior margin broadly convex in lateral view; disc with two oblique rows of long macrosetae extending from central portion and converging on posterodorsal margin. Valvula I, in ventral view ( Fig. 47 ), with basal portion moderately broad, basal margin laterally produced; blade ( Fig. 46 ) similar to that of A. angusta . Valvula II similar to that of A. angusta ; teeth, on median portion, triangular to trapezoidal, moderately (specimen from Guantánamo) or very prominent (specimen from Grand Cayman), 1.5–2 times longer than high, spaced from one another about 1.5 (specimen from Grand Cayman) to twice (specimen from Guantánamo) tooth length; preapical prominence approximately aligned to anteapical tooth.

Material examined. Cayman Islands: Grand Cayman, ten males and twenty females ( BMNH) . Cuba: Guantánamo, one male and two females ( USNM) ; Sancti Spíritus, one male (USNM); uncertain locality, one male ( USNM). Dominican Republic: Barahona, one male (UKL) ; La Vega, two males and three females (BYU).
