Apogonalia mediolineata ( Fowler, 1899)

( Figs 62–66 )

Diagnosis. Anterior dorsum yellow with black marks and conspicuous median yellow stripe. Crown ( Fig. 62 ) with pair of anteromedian diagonal black arches connected to each other medially; posterior half with mosaic. Pronotum ( Fig. 62 ) with pair of lateral yellow arches anteriorly convergent, bordered by black lines. Forewing ( Fig. 62 ) pinkish-red with dark brown veins; clavus with irregular narrow bluish-white stripe adjacent to claval commissure; claval sulcus with dark brown stripe bordered by white stripes; costal area with two adjacent longitudinal stripes, innermost white and outermost dark brown; apex gray. Face ( Fig. 63 ) yellow with black marks. Frons with mosaic of rounded areas bordered by black; dorsally with narrow transverse yellow stripe slightly sinuous. Male pygofer posteriorly concave, long and broad posterodorsal process with apex acute, inner long and tapered ventroapical spine, medially directed. Paraphyses asymmetrical, basal plate V-shaped, right ramus long and broad, left ramus long and moderately narrow. Aedeagal shaft curved ventrally on apical half, paired hook-shaped basiventral processes directed to right side, anteriorly curved. Female sternite VII with pair of lateral large black areas; shape similar to that of A. fraterna . Sternite VIII ( Fig. 64 ) with broad sclerotized plate, anteriorly bilobate and deeply notched medially.

Female length. 8.5–9.6 mm (n = 3).

Description of female genitalia. Sternite VII similar to that of A. fraterna . Sternite VIII ( Fig. 64 ), in dorsal view, with broad, bilobate sclerotized plate; anterior margin with deep and narrow median notch; posterior margin with pair of lateral subtrapezoidal prominences. Pygofer ( Fig. 65 ) similar to that of A. dampfi ; disc with thin macrosetae on central portion, posterodorsal portion and apical 2/3 of posteroventral portion with long macrosetae, posterodorsal margin and apex of posteroventral margin with row of short macrosetae. Valvula I, in ventral view, with basal portion similar to that of A. krameri ; blade similar to that of A. angusta . Valvula II similar to that of A. angusta ; teeth, on median portion ( Fig. 66 ), triangular and elongate, moderately prominent, 3–4 times longer than high, almost not spaced from one another; preapical prominence approximately aligned to anteapical tooth.

Material examined. Mexico: Distrito Federal, two males ( BMNH), one female ( USNM) ; Mexico, two females ( BMNH), one female ( USNM) ; Michoacán de Ocampo, one female ( BMNH) ; uncertain locality, one male (BMNH). USA: Arizona, one female ( USNM) .
