description: <i>Pseudohemihyalea sonorosa</i> Schmidt, sp. n. urn:lsid:zoobank.org:act: E93D6C4F-07C4-42AF-97EE-2C283679E945 Figs. 4, 9, 15, 20, 22, 25 <b>Type material.</b> <b>Holotype –</b> ♁, Mexico, Sonora, Mesa Compañera, 12 mi. w. Yecora, 2600 m, 10-14 Sep 2004, P.A. Opler [CNC]. Paratypes. 2 &amp;female;&amp;female;, same data as holotype [CSU]; 1♁, 4&amp;female;&amp;female;, Same locality as holotype, 10 sep 2004, leg. Bowman and Opler [DEB]. <b>Diagnosis.</b> This species is superficially most similar to <i>P</i>. <i>ambigua</i> and <i>P</i>. <i>potosi</i> <b>sp. n.</b>, but <i>P</i>. <i>sonorosa</i> can be separated from both by its significantly larger size, distinct pink hindwing cast, and late flight period (September vs. June-July). Internally, the uncus is 1.4 x longer than that of <i>P</i>. <i>ambigua</i>, averaging 1.8 mm compared to 1.3 mm in <i>P</i>. <i>ambigua</i>; the uncus has a deeper, narrower basal cleft than <i>P</i>. <i>ambigua</i> (cf. Figs. 15 and 11); compared to <i>P</i>. <i>potosi</i> <b>sp. n.</b>, <i>P</i>. <i>sonorosa</i> has an elongate, not triangular saccular process, and a much longer and narrower valve overall (cf. Figs. 9 and 10). The male vesica is covered in hair-like spines, unlike the small thorn-like cornuti of all other <i>ambigua-</i> group species. In females, the corpus bursae is nearly 3 x as large as the bulla seminalis (fig. 22), compared to about 1.5 x in other members of the <i>ambigua</i> -group. <b>Description. Head <i>–</i></b> male antenna strongly bipectinate, longest rami about 6.0 x longer than segment length; dorsal antennal scales pale rusty brown; vestiture of palps mostly pink with a few rust scales, frons and vertex rust, pinkish red bordering patagia. <b>Thorax <i>–</i></b> vertex of thorax, patagia and tegulae rusty tan, tegulae slightly paler mesially; ventrally, thorax rusty tan tinged with pink; legs rusty tan, pink dorso-medially. <b>Forewing</b> <i>–</i> length (♁) 26.1 mm (<i>n</i> = 2), (&amp;female;) 31.2 mm (<i>n</i> = 2); intervenal areas ivory white, sparsely scaled, semi-translucent; veins broadly lined with rusty tan; fringe and costal margin tan-lined, anal margin with narrow white border; pattern similar ventrally but colours appearing washed-out. <b>Hindwing</b> <i>–</i> sparsely scaled, semi-translucent, pale pink; anal margin more densely scaled with pink scales. <b>Abdomen</b> – pink dorsally, pale tan ventrally; coremata absent. <b>Male genitalia</b> – uncus shaped like a bicycle saddle, i.e., with broad, bilobed base and tapering, finger-like apex; basal lobes heavily setose dorsally, apical portion slightly wider than median, with a spade-shaped dorsal profile; apex bluntly pointed, slightly down curved; division between costal and saccular processes extending slightly less than one-third of total valve length; apex of costal process bluntly rounded, tapering more gradually dorsally than ventrally; saccular process rounded-triangular, tapering to rounded apex; vinculum a short, broad scobinate conical projection; juxta urn-shaped in outline, with medial keel along dorso-ventral axis; saccus short, extending slightly cephalad beyond tegumen; aedeagus without spines; vesica simple, globose, lacking spines but with very fine indistinct cornuti. <b>Female genitalia</b> – lamella antevaginalis broad, flangelike, caudal margin concave; ductus bursae sclerotized, 2 x longer than wide and strongly flattened dorso-ventrally; corpus bursae simple, globose-ellipsoidal, signa lacking; ductus seminalis arising dorsally from caudal part of bursa near junction with ductus; bulla seminalis globose, approximately 1/3 diameter of corpus bursae when inflated. P. ambigua P. syracosia P. sonorosa P. potosi P. fallaciosa P. fallaciosa &amp; P. syracosia <b>Biology and distribution.</b> The immature stages are unknown. <i>Pseudohemihyalea</i> s <i>onorosa</i> flies in upper elevation pine-oak forests of the Sierra Madre Occidental, Mexico during September. It is known only from the type locality, in the state of Sonora. <b>Remarks.</b> The name <i>sonorosa</i> is derived from both its occurrence in the state of Sonora and its pronounced rose-coloured hindwings.
