Apogonalia interrupta (Signoret, 1855)

( Figs 51–56 )

Diagnosis. Anterior dorsum yellow with black marks. Crown with six large black marks, two pairs on anterior margin and one pair between ocelli ( Fig. 51 ). Pronotum ( Fig. 51 ) with pair of anterolateral black maculae adjacent to eyes; mediolateral portions with four anterior black maculae and two posterior ones; disc posteriorly green. Forewing ( Figs 51, 52 ) ochraceous-green with dark brown stripes on veins; corium with anterior portion of costal area yellow; median portion with diagonal dark brown stripe extending from costal margin to inner discal cell; apical portion with two dark transverse stripes. Face yellow with black areas. Frons medially with inverted Vshaped black mark; pair of mediolateral elongate Y-shaped black marks connected to median mark; lateral margin with black stripe. Clypeus with median black stripe. Male pygofer with posterior margin concave, without processes. Paraphyses with Y-shaped basal sclerite, right ramus apical, long and moderately narrowed, left ramus lateromedian, long and strongly narrowed. Aedeagal shaft with long, spiniform dorsoapical process; paired processes on ventroapical portion, right process distinctly shorter than left one. Female sternite VII ( Fig. 53 ) with conspicuous central black macula; shape similar to that of A. imitatrix ; posterior margin medially concave with short central spine. Sternite VIII ( Fig. 54 ), in dorsal view, with inconspicuous, weakly sclerotized arch-shaped plate, expanded medially.

Female length. 6.4–7.0 mm (n = 3).

Description of female genitalia. Sternite VII ( Fig. 53 ) similar to that of A. imitatrix ; posterior margin with median concavity bearing short central spine. Sternite VIII ( Fig. 54 ), in dorsal view, with inconspicuous, weakly sclerotized arch-shaped plate; median portion of plate expanded. Pygofer ( Fig. 55 ) moderately produced posteriorly; posterior margin narrowly convex in lateral view; disc with oblique dorsal row of long macrosetae extending from central portion to posterodorsal margin, posteroventral portion with long macrosetae on apical 2/3. Valvula I, in ventral view ( Fig. 56 ), with basal portion slightly broad; basal margin narrowly convex; blade similar to that of A. angusta . Valvula II similar to that of A. angusta ; teeth, on median portion, very prominent, 1.5 to 2 times longer than high, spaced from one another about twice tooth length; preapical prominence approximately aligned to anteapical tooth.

Material examined. Dominican Republic: Distrito Nacional, one male ( USNM); La Vega, one male and one female (UKL); Puerto Plata, one male ( USNM); uncertain locality, one male and one female ( CMNH).
