Proarna championi Distant 1881: 12 . (Mexico, Purula, Teleman, Guatemala, and Costa Rica)

Remarks. Torres (1963) reassigned this species to the genus Pacarina Distant, 1905d based on the head being about as wide as the mesonotum, the lateral margins of the pronotum being angles and not expanded, the well developed and dorsally concave timbal covers, position of the opercula, basal pygofer lobe shape and the macular pattern of the fore wings. However as illustrated in Fig. 3 , this species does not possess a head that is wider than the mesonotum with eyes that project laterally beyond the anterior angles of the pronotum, the smoothly sloping epicranium towards the postclypeus, the laterally arched pronotum, the perpendicular radial and slightly oblique radiomedial crossveins, the abrupt facial color change, nor the broadly triangular timbal covers with a rounded apex that are characteristic of Pacarina ( Distant 1905d; Sanborn et al. 2012) so the species cannot be classified within Pacarina . Instead, the head is about as wide as the mesonotum with the eyes scarcely projecting beyond the anterior pronotal angle, the epicranium is bent near a right angle anteriorly, the pronotum does not arch laterally, the radial crossvein is oriented vertically to radius anterior 2 and radius posterior veins and the radiomedial crossvein is obliquely oriented, and sharply triangular timbal covers with pointed apex are all characteristics of the genus Proarna . The opercular shape, position of the basal pygofer lobes, and macular pattern of the fore wings are similar in both genera. Fig. 3 clearly shows Proarna championi n. comb. is more similar in its morphology to P. hilaris ( Germar, 1830) than it is to Pacarina puella Davis, 1923 , the type species of each genus. As a result, I return the species to the genus Proarna to become Proarna championi Distant, 1881 n . comb. once again.

This is one of the smaller Proarna species in Panama. It can be distinguished by the fore wing infuscation only on the radial and radiomedial crossveins and proximal and distal radius anterior 2. The radial crossvein intersects apical cell 1 about two-thirds distally. Fresh specimens have dense white pubescence on the dorsolateral abdominal tergites. The species emerges at the beginning of the rainy season with adults acrtive between late May and late June ( Wolda 1988; 1989).

Distribution. The species has been reported from Belize, Costa Rica, El Salvador, Guatemala, Honduras, Mexico, Nicaragua, and Panama ( Metcalf 1963a; Sanborn 2013; 2014). The species has been reported from Barro Colorado Island, in the Panama Canal Area, 120m altitude in lowland forest ( Wolda 1988; 1989; Wolda & Ramos 1992) and Las Cumbres, Province of Panama, 150 m altitude in secondary growth forest ( Wolda & Ramos 1992) in Panama.
