Description

MORPHOLOGY. External morphological characters as in generic description.

COLORATION (male and female). Head and thorax ( Figs 1–3View Figs 1–9) yellowish brown. Crown with pair of rounded black spots equidistant between eye margin and median line. Face ( Fig. 2View Figs 1–9) without maculae. Pronotum ( Figs 1, 3View Figs 1–9) with black markings near anterior margin; disk and posterior third dark-brown. Mesonotum ( Fig. 1View Figs 1–9) with two pairs of black spots, one pair near lateral angles and one medially near scutellum; scutoscutelar suture black. Forewing ( Figs 4View Figs 1–9, 28–29View Figs 28–29) yellowish brown; membrane translucent; appendix smoky. Hind wing ( Fig. 5View Figs 1–9) grey with darker veins. Legs ( Fig. 29View Figs 28–29) yellowish brown.

MALE TERMINALIA. Sternite VIII ( Fig. 10View Figs 10–20) longer than wide; lateral margins slightly rounded; apex tapered and rounded. In dorsal view, pygofer ( Fig. 11View Figs 10–20) with basal portion well sclerotized forming unbroken ring dorsally; lateral lobe articulated with base by flexible membranous cleft and approximately as long as basal portion; macrosetae dispersed on lateral lobe except on anteroventral portion; apex obliquely truncated. Ventral process of pygofer ( Figs 12–14View Figs 10–20) slender, almost straight, slightly shorter than subgenital plate; laterally with small rounded lobe near base, apex acute and bent ventrally. Subgenital plate ( Fig. 15View Figs 10–20) slender and slightly tapered to apex, 5.5 times longer than wide; setae on ventral surface and external margin; apex rounded. Connective ( Fig. 16View Figs 10–20) slightly longer than basal width; stalk very wide, straight, with keel dorsally. In dorsal view, style ( Fig. 17View Figs 10–20) with apodeme moderately short, produced laterally; apophysis elongate, slender, apex slightly directed laterally; microsetae present, forming small group near base of apophysis and dispersed laterally on mid-portion; in lateral view ( Fig. 18View Figs 10–20), apodeme directed dorsally; apophysis curved near base, tapered towards apex; apex acute, slightly curved dorsally. Aedeagus ( Figs 19–20View Figs 10–20) with preatrium and dorsal apodeme developed, flattened, twice as wide as shaft; shaft very long, almost straight, weekly compressed laterally, except for apex and base; shaft apex with two pairs of processes directed dorsally, lateral pair slightly arched and longer than median pair, which is shorter and straight.

FEMALE TERMINALIA. Sternite VII ( Fig. 21View Figs 21–27) 1.5 times wider than long, approximately rectangular; posterior margin broadly rounded, slightly produced posteriorly on median potion medially. Pygofer ( Fig. 22View Figs 21–27) about two times as long as maximum height; ventral margin broadly rounded; apex tapered and rounded. First valvifer ( Fig. 23View Figs 21–27) as high as long, margins straight, posteroventral corner rounded.

Remarks

The clypeus and lorum of the male specimens are morphologically similar to those of the females. It differs from species of Daveyoungana  that have the clypeus and lorum sexually dimorphic, as described by Dai & Dietrich (2015). The specimens from the state of Paraná were collected with a suspense light trap placed at approximately 20 m above the soil.
