THAILAND : Southern Isaan: 2 females , Khao-Yai National Park, 750 m , 26 July 1962 , E. S. Ross and D. Q. Cavagnar ( CAS ). Chiang Mai Province: 1 male , near Chiang mai, Doi Suthep, 1150 m , 30 November 1996 , P. Schwendinger ( MHNG ). Chumphon Province: 1 male 1female , near border Lang Suan-Phato Distr. Khao Kai Jae Waterfall, 80 m , semi evergreen rainforest, 21–22 August 2004 , P. Schwendinger ( MHNG ). INDONESIA : Sumatra Barat: 1 female , Mangani, Mine near Kota Tinggi, 700 m , 21 July 1983 , Edward S. Ross ( CAS ). Diagnosis. This is the most common and widely distributed species of the genus. Males are separated by the long tapering E and MA. Females are separated by the round anteriorly boarded CO ( Figs 27 A–E), and the lack of a narrow MR, which is present in C. srivijaya sp. nov. . Further, this species can also be easily separated by the presence of PME, which is lacking in C. srivijaya sp. nov. , the only other illustrated species of the genus. Variation. The specimens examined show some variation in the shape RTA, E and MA ( Figs 27 B, 27C; Tang & Li 2010 ; Tang et al. 2009). Distribution. China , Indonesia , Philippines , Singapore , Thailand . Its presence is predicted in Burma , Vietnam and possibly in North India . Remarks. Libania is regarded by Lehtinen (2002) as a synonym of Cebrenninus . The variation in the male genitalia of the specimens examined (but not the corresponding female genitalia) might suggest that more than one species is involved.
