Barsine cruciata ( Walker, 1862)

( Figs 24–29 , 42 , 52 )

Hypoprepia cruciata Walker, 1862 , Journal of the proceedings of the Linnean Society (Zoology) 6: 101 (Type locality: [Borneo] “ Sarawak ”).

Type material examined. Syntypes: 1 ♀, “ Borneo , Sarawak, A.R. Wallace, 57–36” / round label with a green circle “Type” / “ Barsine cruciata ” / label with QR-code “ NHMUK010598510 ” (Coll. NHMUK) ; 1 ♁, “SAR” / “ Coll. Wallace, Higgins 1871” / “ cruciata ” / “A” / “483” / “ TYPE LEP.: No. 458 1/2 Hypoprepia cruciata Walker HOPE DEPT. OXFORD” (Coll. OUMNH); 1 ♁, “SAR” / “ Barsine cruciata ♁ Hk 31.249 Type in BM ” / “A” / “483” / “ TYPE LEP.: No. 458 2/2 Hypoprepia cruciata Walker HOPE DEPT. OXFORD” (Coll. OUMNH) .

Other material examined. Series of both sexes from Thailand (Nan, Kanchanaburi, Chumphon, Surat Thani, Nakhon Si Tammarat and Phathalung provinces), Malaysia (Malay Peninsula and Borneo Island) and Indonesia (Sumatra and Java Islands) (Colls NHMUK, MWM / ZSM, CKC).

Diagnosis. Forewing length is 11–12.5 mm in males and 13.5–15.5 mm in females. Barsine cruciata resembles externally B. flavodiscalis , but differs by its paler and less contrast discal yellow spot of forewing, and paler, reddish hindwing without a bright yellowish spot at apex. The male genital capsule of B. cruciata differs clearly from that of B. flavodiscalis by its shorter and more curved uncus, larger vinculum, much less curved costa with a very small medial process, reduced distal costal process, setose basal part of sacculus, large, trigonal distal saccular process (reduced in B. flavodiscalis ), and extremely long, narrow and apically pointed medial costal process situated more distally than that in B. flavodiscalis ). The vesica of B. cruciata differs from that of B. flavodiscalis by another configuration of diverticula having fields of very weak granulation and a large, spine-like one at a sclerotized and shortly dentate plate. The female genitalia of B. cruciata differ from those of B. flavodiscalis by the absence of lateral lobes of ostium bursae, the broader ductus bursae, the posterior section of corpus bursae being broadened and having stronger spinulose scobination and a narrow lateral diverticulum, the posterior section of corpus bursae being smaller and having no signum, and the shorter appendix bursae directed posteriorly (whereas in B. flavodiscalis that is directed inwards).

Distribution. Thailand (Nan, Kanchanaburi, Chumphon, Surat Thani, Nakhon Si Tammarat and Phathalung provinces) ( Černý & Pinratana 2009), Malaysia (Malay Peninsula and Borneo) ( Holloway 2001; Bucsek 2012), Indonesia (Sumatra, Java) ( Hampson 1900). The record for South West China (Yunnan, Sichuan) ( Fang 2000) is doubtful and most probably belongs to B. dejeani .
