Enghoffosoma anchoriforme Likhitrakarn, Golovatch & Panha, 2014: 503 , figs 11–13.

Material examined. 3 males, 2 females (IEBR-Myr 106), Vietnam, Dong Nai Prov., Cat Tien National Park, forest, 25–26 September 2004; 2 males, 1 female (IEBR-Myr 122), Vietnam, Dong Nai Prov., Cat Tien National Park, forest, 26 September 2004, all leg. Anh Duc Nguyen & S.I. Golovatch; 1 male, 1 female (IEBR-Myr 108), Vietnam, Dak Lak Prov., Yok Don National Park, forest along stream, 20 June 2007, leg. Hiep Duc Nguyen; 1 male, 1 female, 1 juv. (IEBR-Myr 521), Vietnam, Dak Lak Prov., Yok Don National Park, deciduous forest, on the way to station No. 6, 9 June 2013, leg. Phung T.H. Luong.

Remarks. This species has only been known from Champasak Province, Laos ( Likhitrakarn et al. 2014). The above samples from Vietnam are larger than the holotype from Laos: 44–46 mm vs 34 mm long, 4.4 mm vs 4.1 mm wide on metazonae. In other respects, the new material fully agrees with the original description, also extending the species’ distribution by about 800 km to the southeast. This alone suggests this species to be widespread across southern Laos and highland Vietnam.
