Diagnosis.

This species is unique in the genus because of its abdominal pigmentation: terga pale yellow medially and reddish laterally. The male genitalia have an obvious projection between the two lobes. The larvae of this species are larger and have more pale dots and marks on head and body than those of the other known species (Figs 7, 9, 10, Zhou and Zheng 2003), gill 5 or 6 are provided with a small, thin projection (Fig. 8).

Habitat and biology.

Larvae of Afronurus rubromaculata were the only representatives of Afronurus encountered in the large river Mekong in February 2002 along the Thai-Laos border in the utmost north of Thailand. It is regularly found as a resident together with the dominant Afronurus namnaoensis on stones and rocks in Nam Lang River, altitude 600 m (Braasch 2006). This species is also found in Vietnam.

Remarks.

The larva and adults of Afronurus rubromaculata were adequately described by You et al. (1981), Wu et al. (1986) and Zhou and Zheng (2003). Only larva of Afronurus rubromaculata was reported in Thailand ( Braasch and Boonsoong 2010).
