( Figs 1, 2 , 19, 20 , 33 ) Prabhasa flavicosta Moore, 1878 , Proceedings of the Scientific Meetings of the Zoological Society of London 1878 : 26, pl. 2, fig. 17 ( Type locality: [NE India , Meghalaya , Khasi Hills , Cherrapunji ] “ Cherra Punji ”). Type material examined . Syntype ( Fig. 2 ): ♀ , “Cherra | ♀ | Atkinson | 26” / “ Prabhasa flavicosta type Moore” / “Moore Coll. 94-106” / red ring “Type” label / QR-code label with unique number “ NHMUK010401748 ” ( NHMUK ) . Additional material examined . 1 ♂ , 1 ♀ , Khasia Hills , Assam Nissary , gen. slide No. : BMNH Arct. 4889 (male), unique numbers: NHMUK 010914124 (male) and 010914127 (female) ( NHMUK ); 1 ♀ , Assam , Cherrapunji , X.1916 , Native Collector , Brit. Mus. 1926-142, Ilema flavicosta Mo. , unique number: NHMUK 010914125 , gen. slide No. : BMNH Arct. 4890 ( NHMUK ) ; 1 ♂ , Khasis , Nat. Coll. , Joicey Bequest , Brit. Mus. 1934-120, unique number: NHMUK 010914126 , gen. slide No. : NHMUK010313950 (prepared by Volynkin ) ( NHMUK ). Remark . Holloway (2001) reported the species for Borneo based on a single female specimen from Pulo Laut. Unfortunately, the second author of the present paper did not locate this specimen in the NHMUK collection. However, despite the external similarity of adults, the female genitalia illustrated by Holloway (2001 : fig. 92) display remarkable differences from those of the true D. flavicosta from Khasi Hills and obviously belong to another, unknown species. Distribution . The species is known only from Northeastern India ( Meghalaya ) ( Moore 1878 ). Reporting of this species from Thailand ( Černý & Pinratana 2009 ) is due to wrong identification.
