Diagnosis

This genus differs from all other Neotropical genera of Tephritidae by its entirely dark brown wing pattern and in having rows of teeth­like spines on the base of the phallus ( Figs. 5, 6 ). It runs to the “Platensinini” in the key of Foote (1980) but differs from all of the genera included there by its wing pattern. It clearly belongs to the Tephritinae , but within this group its relationships are unclear. It may be closest to Acrotaenia and related genera based on its chaetotaxy (nonsetulose frons, acuminate lateral vertical seta, setulose R4+5), head shape, and venation (lobe of cell bcu moderately large).

Description

Head: In lateral view higher than long, nearly oval, frons and face curving together without distinct angle or at strongly obtuse angle. Lunule large, length subequal to width. Frons nonsetulose medially, with 3 frontal setae and 2 acuminate reclinate orbital setae. Medial vertical seta yellow, acuminate, well developed; lateral vertical seta paler yellow, sometimes slightly lanceolate, half to 2/3 as long as medial vertical seta. Postocellar and postvertical setae well developed, white, lanceolate. Postocular setae mixed small, dark acuminate and large, white, lanceolate.

Thorax: Postpronotal, anterior and posterior notopleural, presutual and postsutural supra­alar, intra­alar, postalar, dorsocentral, acrostichal, 2 scutellar, 1–2 anepisternal, anepimeral, and katepisternal setae well developed, yellow to pale brown, acuminate. Dorsocentral seta closer to transverse suture than level of postsutural supra­alar seta. Apical scutellar seta 2/3 as long as basal seta, longer than scutellum.

Legs: Hind femur with anterodorsal and posterodorsal preapical setae.

Wing ( Fig. 1 ): Entirely brown, including basal cells, alula, and anal lobe. Without bullae or argents (spots due to microtrichia color). Costal setulae at subcostal break short, no more than 2 times as long as other costal setulae. Vein R1 dorsally without gap in setulae near bend in vein Sc. Vein R4+5 dorsally evenly setulose to level of apex of R2+3, ventrally setulose to beyond level of r­m. Pterostigma 2.0–2.3 times as long as wide. Lobe of cell bcu subequal in length to width of cell.

Male terminalia: Lateral surstylus simple, without posterodorsal lobe. Medial surstylus with 2 stout prensisetae. Base of phallus ( Figs. 5–6 ) swollen and with two rows of tooth­like spines.

Female terminalia: Eversible membrane similar dorsally and ventrally, with short taenia 1/3 length of membrane, and single broad oval area of moderate sized triangular spicules, largest subbasally, gradually tapering distally. Aculeus tip simple. 2 spermathecae.
