Apogonalia germana ( Fowler, 1899)

( Figs 29–39 )

Diagnosis. Anterior dorsum ( Figs 29, 30 ) yellow with brown marks. Crown with anteromedian pair of diagonal brown arches connected medially; posterior half with mosaic. Pronotum with posterior portion pink ( Fig. 29 ) or yellow ( Fig. 30 ); disc almost entirely with mosaic of small areas bordered by brown; mediolateral portions with ( Fig. 30 ) or without ( Fig. 29 ) pair of roundish yellow maculae. Forewing ( Figs 29, 30 ) pink with small dark red marks; basal portion of corium with or without white areas; apex gray. Face ( Fig. 31 ) yellow with brown marks. Frons with mosaic of rounded areas bordered by brown; brown lines on muscle impression areas. Clypeus with ventral brown macula. Male pygofer without processes. Paraphyses variable, with left ramus minute or long. Aedeagal shaft with pair of hook-shaped to falciform, strongly asymmetrical ventral processes ( Young 1977, figs 754f, s–u). Female sternite VII similar to that of A. fraterna , or with conspicuous median concavity on posterior margin ( Fig. 32 ), or continuously narrow posteriorly from median portion, with slight median concavity on posterior margin ( Fig. 33 ). Sternite VIII with transverse sclerotized plate slightly depressed on median line, with anterior and posterior margins variable ( Figs 34, 35 ). Valvula I, in ventral view, with basal portion very broad ( Fig. 38 ). Valvula II with teeth elongate on median portion ( Fig. 39 ).

Female length. 10.7–12.4 mm (n = 4).

Description of female genitalia. Sternite VII similar to that of A. fraterna ( Fig. 25 ) (specimen from Michoacán de Ocampo), or with conspicuous median concavity on posterior margin ( Fig. 32 , specimen from Veracruz-Llave), or continuously narrow posteriorly from median portion, with slight median concavity on posterior margin ( Fig. 33 , specimen from Puebla). Sternite VIII, in dorsal view, with transverse sclerotized plate; anterior margin of plate broadly convex ( Fig. 34 , specimen from Michoacán de Ocampo) or irregularly emarginated ( Fig. 35 , specimen from Veracruz-Llave), with small median concavity; dorsal surface with slight, longitudinal median depression; posterior margin subtruncate ( Fig. 34 ) or broadly convex and irregular ( Fig. 35 ); lateral portions with ( Fig. 35 ) or without ( Fig. 34 ) pair of narrow, oblique sclerotized areas. Pygofer moderately produced posteriorly; posterior margin, in lateral view, broadly convex ( Fig. 37 , specimen from Veracruz-Llave) or triangular and with apex narrowly convex ( Fig. 36 , specimen from Michoacán de Ocampo); disc posteriorly with long macrosetae on dorsal portion and apical 2/3 of ventral portion. Valvula I, in ventral view ( Fig. 38 ), with basal portion very broad; basal margin slightly concave, with short lateral prominence; blade similar to that of A. blanchardi . Valvula II similar to that of A. blanchardi ; teeth, on median portion ( Fig. 39 ), triangular and elongate, moderately produced, 3–4 times longer than high, spaced from one another about one time tooth length (specimen from Michoacán de Ocampo) or 0.5 tooth length (specimen from Veracruz-Llave); preapical prominence approximately aligned to anteapical tooth (specimen from Veracruz-Llave) or apical tooth (specimen from Michoacán de Ocampo).

Material examined. Mexico: Hidalgo, one male ( USNM) ; Michoacán de Ocampo, one female ( USNM) ; Puebla, one male and one female ( BYU); Veracruz-Llave, one male and one female ( BYU), two males and one female ( USNM).
