The genus Crypsithyris Meyrick (Lepidoptera: Tineidae) in Guangdong Province, China, with comments on the biology and the description of a new species Author Huang, Guo-Hua Author Hirowatari, Toshiya Author Wang, Min text Zootaxa 2009 2310 51 58 journal article 10.5281/zenodo.191849 a4890cd1-9b47-43e6-b93a-b29c944cb14f 1175-5326 191849 Crypsithryis nanlingensis Huang, Hirowatari et Wang , sp. nov. Figs. 1 A–B, 2A, 3A–B Diagnosis. This new species resembles Crypsithyris hebeiensis Xiao & Li, 2005 , but can be distinguished from it by the following: forewing with subhyaline spot surrounded by black scales; saccus broadly triangular and slender from basal 0.66; aedeagus nearly straight with apex curved ventrally; corpus bursae lanternshaped with a few indistinct signa; and papilla analis strongly developed and sclerotized, broadly bilobed with pointed apex. In C. hebeiensis , the black scales of the forewing subhyaline spot are indistinct, the saccus is long with a rounded expanded distal end, and the aedeagus is arched. Description . Head : Vertex and face roughly covered with dense, erect, yellowish creamy scales. Antenna filiform and slender, scape smooth-scaled with pecten. Frons with long yellowish creamy hairs. Maxillary palpus covered with yellowish pale scales. Galea indistinct. Labial palpus covered with short yellowish white scales dorsally and dark brown ventrally, on the second segment with more than 10 bristles. FIGURE 2. Wing venation. A. C. nanlingensis , sp. nov. , holotype, male; B. Crypsithyris sp., female; C. Crypsithyris japonica Petersen & Gaedike, 1993 , male. Thorax : Dorsum smooth with dense yellowish white scales; tegula yellowish gray with black scales at basal 0.66. Legs extensively covered with brownish pale scales; hind tibia bearing dense long brownish yellow hairs. Forewing length 5.0– 5.1 mm in male, 5.6 mm in female; antenna longer than 5.0 mm. Forewing elongate, about 4.0X as long as wide including fringe (about 3.7X as long as wide excluding fringe), with yellowish gray fringe restricted to termen; ground color yellowish creamy irrorated with black scales; costa black from base to basal 0.8; subhyaline spot in discoidal cell surrounded by black scales. All veins free ( Fig. 2 A), except R1 and 2A absent, R4 and R5 long-stalked, and M2 and M3 short-stalked. Hindwing elongate, 1.9X as long as wide including fringe (4.1X as long as wide excluding fringe); ground color yellowish brown, apex roundly produced; all veins free ( Fig. 2 A), costa arched. Abdomen : Dorsum yellowish gray, heavily irrorated with brown scales; venter mostly white; abdominal segment VIII without coremata. Male genitalia ( Fig. 3 A) with uncus elongate, triangular, strongly tapered, fused with tegumen, apex acute; gnathos bilobed, slender, strongly sclerotized, articulated with tegumen at the base; tegumen and vinculum fused into a ring, tegumen broad and vinculum narrow. Juxta indistinct. Subscaphium membranous, saccus broadly triangular but distal 0.33 slender, nearly 0.75X length of valva, valva elongate, nearly straight, distal half rectangular, a distinct digitate costal projection present at the middle, inner surface with thin bristles. Aedeagus cylindrical, slender, nearly straight but curved at apex, about 1.7X length of valva; vesica with a pair of slender cornuti which nearly 0.33X length of aedeagus. Female ( Fig. 3 B) with segment VIII very narrow, with bands of dense thick bristles around. Ovipositor short, about 0.75X length of apophyses anteriores; papilla analis well developed, sclerotized, broadly bilobed with apex weakly pointed; apophyses posteriores long, about 1.3X length of apophyses anteriores; bursa copulatrix very long, nearly 3X length of apophysis anterioris. Ductus bursae narrow, thin-walled, with membranous colliculum in anterior region. Corpus bursae lantern-shaped with some indistinct signa. Holotype .
