Revision of the Agathidinae (Hymenoptera, Braconidae) of Vietnam, with the description of forty-two new species and three new genera Author van Achterberg, Cornelis Author Long, Khuat Dang text ZooKeys 2010 54 1 184 http://dx.doi.org/10.3897/zookeys.54.475 journal article http://dx.doi.org/10.3897/zookeys.54.475 1313-2970-54-1 Cremnops atricornis (Smith, 1874) stat. n. Figs 111-113 Distribution. NE Vietnam: Phu Tho, Ha Giang, CN Vietnam: Nghe An and S Vietnam: Kien Giang, Ninh Thuan, Dong Nai. New record. Outside Vietnam known from China (Hunan; Liaoning; Shanxi; Taiwan), India, Indonesia (Java), Japan and Korea . Figures 111-113. Cremnops atricornis (Smith), female, Cat Tien National Park. 111 habitus lateral 112 head anterior 113 head dorsal. Diagnosis. Very close to Cremnops desertor (Linnaeus, 1758). The traditionally used differences for separation are not sufficient and, consequently, it was synonymised by Sharkey (1996) . Both species are very variable in colour, especially the extension of the dark parts of the wing membrane is variable and thus useless for diagnosis. Neverthe less , it is possible to separate the West Palaearctic typical specimens of Cremnops desertor from the East Palaearctic and Oriental specimens (including Cremnops atricornis ) by the relative length of the fore tarsus of the females. In Cremnops desertor the fore tarsus is distinctly longer than the fore tibia and (including claws) about as long as the tibia in Cremnops atricornis . The Vietnamese specimens have the first tergite 1.5-1.8 times as long as its apical width (up to 2.2 times in East Palaearctic specimens according to Sharkey (1996) ) and the vertex is yellowish-brown (Fig. 113).
