Etymology. The species name is derived from the shark genus Squalus  in reference to the sharkfin-like process on the dorsal margin of the male valva.

Diagnosis. Head with frontal protuberance. Male genitalia: dorsal margin of valva smooth with sharply pointed triangular process at about 1/4 from apex; vesica with single large subbasal cornutus and a spine-covered diverticulum near apex. Female genitalia: ostial plate protruding, wedge shaped with convex sides, posterior margin cleft in middle 1/3 to base.

Description. Adult: Head – Frontal protuberance crater-like, nearly circular, flattened above haustellum. Thorax – Yellow with brown flecks. Legs: yellow, flecked with brown scales, more heavily on forelegs and middle legs, and in females. Wings (both sexes): DFW lemon yellow with dark discal spot and additional dark spot in fold at 1/4 from wing base; usually a smaller third spot below costa at 1/4 from base; a thin orange-brown postmedial line evenly curving around discal spot in most specimens. DHW fuscous. VFW yellowish buff, heavily infused with brown scales with well-defined pale band along inner margin. VHW yellowish, moderately flecked with brown scales, indistinct brown marginal line; in some specimens a suggestion of a brown discal spot and postmedian line. Male genitalia – Uncus: decurved, slender, expanded slightly apically with blunt rounded tip. Valvae: symmetrical, basally broad tapering to approximately middle (at apex of sacculus), then narrowing to a rounded apex, without corona; dorsal margin with prominent, sharply-pointed, triangular process at about 1/4 from apex; sacculus broad with slightly pointed rounded apex and with

small spines sparsely distributed along dorsal margin. Aedeagus: smoothly sclerotized; vesica with single large dorsal cornutus projecting anteriorly, a flat sclerotized plate by opening into ductus ejaculatorius, and with long, tapered, spine-covered diverticulum to left of ductus ejaculatorius. Female genitalia – Corpus bursae ovoid without surface features, tapered posteriorly; ductus seminalis arising on left near junction with ductus bursae. Anterior 1/2 of ductus bursae lightly sclerotized, narrow at opening to corpus bursae, then expanded to sclerotized posterior part; a thumb-like diverticulum on ductus bursae on right just posterior to constriction at corpus bursae; posterior 1/2 of ductus bursae well sclerotized with a pleated-like (corrugated) section. Ostial plate an elongate wedge with concave sides, convex posterior margin cleft in middle 1/3 to base.

Distribution and biology. Arizona and southward to Costa Rica. Flight season is from mid-July to mid-August in Arizona and from late May in Costa Rica.
