Material examined. 2 males (IEBR-451) Da Nang, Ba Na National Park (15°59′44.4″N; 107°59′39.13″E); forest, 1,200 m a.s.l., July 2009, coll. Truong Xuan Lam.

Diagnosis. This species can be distinguished from its congener by: metaterga faintly rugose, with two rows of 2+2 and 4+4 setae borne on minute knobs in front of and behind transverse sulcus, respectively; paraterga well developed, set higher than metatergal surface, with long protruding caudal corner. Tip of gonopod strongly divided into two lanceolate lobules.

Remarks. The species Antheromorpha paviei ( Brölemann, 1896) was described as Orthomorpha paviei . It was questionably relocated to the genus Prionopeltis , then to the genus Pratinus ( Attems, 1914, 1937). Jeekel (1963) assigned this species back to the genus Orthomorpha , however, he still questioned its generic status. Recently, this species was transferred to the genus Antheromorpha due to the deeply split tip of its gonopod.

This species has been reported from Thailand and Laos ( Enghoff, 2005; Likhitrakarn et al., 2014, 2016). This is the first time the species is recorded for Vietnam.
