Corupá, Santa Catarina, Brazil.

Diagnosis. —

This species is separated from other species of Apterotrypa by the following characteristics: posterior margin of pronotum with two lines; supra-anal plate elongated medially, small projection on posterior margin; subgenital plate dark yellow; m half the size of LLophi; PsP reaches apex of LLophi; ectophallic fold posterior margin extending beyond posterior margin of pseudepiphallic sclerite in ventral view.

Description. —

Head: Occiput smooth. Vertex pubescent. Fastigium wider than long, with bristles (Fig. 8 D). Ocelli absent. Frons pubescent (Fig. 8 C). Antennal scapes longer than wide in lateral view, pubescent. Genae smooth. Maxillary palps: article 3 the longest; article 4 and 5 almost equally sized; article 5 strongly clavate, with bristles (Fig. 8 C). Thorax: Pronotum longer than wide in dorsal view, covered by bristles. Dorsal disc of pronotum cephalic margin almost straight; caudal margin almost straight (Fig. 8 A, D). Lateral lobe of pronotum ventro-cephalic angle slightly curved; ventro-caudal angle slightly ascending (Fig. 8 E). Wings absent. Legs: Legs I and II with bristles. TI with three apical spurs: two inner spurs equally sized and one outer spur longer than internal ones. TII with four apical spurs: two internal spurs equally sized and two external spurs equally sized, external spurs longer than internal ones. FIII longer than TIII, with bristles. TIII subapical spurs formula: 4 / 5, one to three spines between each pair of subapical spurs; six to eight spines above basal subapical spurs on both sides. TIII apical spurs formula: 3 / 3, internal ones longer. TIII inner apical spurs: iad> iam> iav; outer apical spurs: oam> oad> oav, oav and oad almost equally sized. TIII apical and subapical spurs with curved apex. Basitarsus with four spines on outer side and one on inner side; two apical spurs, one each side equally sized. Abdomen: Tergites pubescent (Fig. 8 A). Cerci pubescent. Supra-anal plate pubescent, medially elongated, posterior margin extended (Fig. 8 H).

Male. Posterior margin of pronotum covering metanotum. Metanotum with a globular structure in medial region, two lines almost meeting medially on posterior margin (Fig. 9 G). Subgenital plate longer than wide, posterior margin nearly straight, convex in lateral view (Fig. 9 I).

Male genitalia: (Fig. 9 A – D; Fig. 10 A – C) Pseudepiphallus: Pseudepiphallic sclerite nearly straight in lateral view (Fig. 9 C); anterior margin concave on medial region. Lateral lobe of pseudepiphallus inclined inward in dorsal and ventral views (Fig. 9 A, B), apex slightly curved dorsally in lateral view (Fig. 9 C), rounded in dorsal and ventral views (Fig. 9 A, B); internal margin membranous, 1 / 3 the size of sclerotized portion. Pseudepiphallic paramere apex reaches margin of lateral lobe of pseudepiphallus in ventral view (Fig. 9 B), posterior portion divided into two lobes, extending beyond posterior margin of pseudepiphallic sclerite in dorsal and ventral views (Fig. 9 A, B); apex of external lobe longer than apex of internal lobe in ventral view (Fig. 9 B), slightly inclined ventrally in lateral view (Fig. 9 C). Rami elongated, longer than pseudepiphallic sclerite, less sclerotized in anterior portion. Ectophallic invagination: Ectophallic apodeme slightly longer than lateral lobe of pseudepiphallus, straight and inclined outward in dorsal and ventral views (Fig. 9 A, B); arc open, posterior portion directed distally; ventral projections of ectophallic invagination reduced, shorter than the arc. Ectophallic fold asymmetrical in ventral view (Fig. 9 B), anterior portion slightly curved, diverging from endophallic sclerite. Endophallic sclerite: Elongated, dorsoventrally flattened, with diagonal lines throughout the structure, equal length to ectophallic apodeme in ventral view (Fig. 9 B); anterior portion curved ventrally in lateral view (Fig. 9 C); posterior margin unsclerotized, extending beyond posterior margin of pseudepiphallic sclerite in ventral view (Fig. 9 B); endophallic apodeme absent.

Female. Body larger than male. Metanotal structure below posterior margin of pronotum, similar to male (Fig. 8 B – red arrow). Subgenital plate wider than long, posterior portion slightly convex, posterior margin slightly curved inwards, pubescent (Fig. 8 K). Supra-anal plate similar to male, posterior portion rounded, longer than wide in ventral view (Fig. 8 J). Ovipositor curved upward in lateral view, margins serrated near the apex, pointed (Fig. 8 L, M). Female genitalia: (Fig. 9 E – G) Copulatory papilla cylindrical, longer than wide in ventral view (Fig. 9 G). Distal margin rounded in dorsal and ventral views, less sclerotized (Fig. 9 E, G). Medial portion of posterior margin less sclerotized in dorsal view (Fig. 9 E). Ventral face longer than dorsal face in lateral view (Fig. 9 F). Opening at ventral region D-shaped (Fig. 9 G).

Coloration: Male coloration similar to female (Fig. 8 A, B). Occiput and vertex dark yellow, bristles dark yellow; fastigium light yellow (Fig. 8 D). Frons whitish-yellow. Genae yellowish.

Abdominal tergites light yellow (Fig. 8 A, B). Supra-anal plate light yellow, posterior margin black (Fig. 8 H). Subgenital plate anterior portion light yellow, posterior portion dark yellow (Fig. 8 I). Female subgenital plate light yellow (Fig. 8 K). Cerci yellowish. Ovipositor with internal margin yellowish, lateral margins and distal portion light yellow (Fig. 8 L, M). Legs I and II bristles yellow. FI and FII light yellow. TI and TII light yellow.
