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 Crypsithyris Meyrick, 1907 Crypsithyris Meyrick, 1907 , J. Bombay nat. Hist. Soc. , 17 : 752. Type-species: Crypsithyris mesodyas Meyrick, 1907 , J. Bombay nat. Hist. Soc. , 17 : 753, by original designation. Type locality: Sri Lanka . Crypsithyris species are small- to medium-sized moths, with a forewing length of 3.5–6.0 mm. The antenna is as long as or longer than the forewing; the maxillary palpus is 5-segmented; and the labial palpus has bristles laterally and apically. The forewing has a subhyaline spot in the discoidal cell (indistinct in some species) and lacks vein R1, and in the hindwing CuA2 is short. In the male genitalia, the valva is elongate; the saccus is triangular or rod-shaped; the juxta usually is elongate, separated from the vinculum; and the transtilla usually is developed. The female genitalia are unique, with a lantern-shaped corpus bursae surrounded by a flangeshaped sclerite bearing spinelike processes; abdominal segment VIII is narrow, circumfused with dense strong thick bristles. Diagnosis . Superficially, Crypsithyris Meyrick, 1907 , Monopis Hübner , [1825], Miramonopis Gozmány, 1966 , and Crypsithyrodes Zimmerman, 1978 share a characteristic subhyaline spot on the forewing ( Meyrick 1907 ; Gozmány 1966 ; Zimmerman 1978 ). However, Crypsithyris is distinguished easily from those genera by the absence of forewing vein R1 and by the presence of a lantern-shaped corpus bursae. Crypsithyris also differs in the following characters: in Monopis the juxta of the male genitalia is fused with the vinculum, whereas it is not in Crypsithyris ; in Crypsithyrodes all M- and Cu-branches of the forewing are free, and the uncus is T-shaped, whereas in Crypsithyris R4 and R5 of the forewing are long-stalked or fused, and the uncus is elongate-triangular with a minute hook at the apex; and in Miramonopis the aedeagus bears a thorn-like subapical carina ( Robinson & Nielsen 1993 ) that is lacking in Crypsithyris . The larval cases of C. japonica , C. saigusai , and C. cana are similar to those of Tinea species: oblong and flat, weakly constricted and with an opening at each, and the dorsal and ventral surfaces are weakly convex ( Sakai & Saigusa 2002 ). The cases are spun with silk and covered with sand grains. Distribution. The genus occurs in China , Korea , Japan , Indonesia , Burma , India , Sri Lanka , Ethiopia , Uganda , Mozambique , Zaire , Zimbabwe , Ghana , Central African Rep., Congo , Rhodesia , Sierra Leone , South Africa , Australia , Samoa , and the Society Islands.
