Vestalaria

The five species of the genus range from China through Indochina, Thailand and Myanmar to north-east India and are fairly closely related. The larva is known for just one species, Vestalaria venusta (Hämäläinen) (Wang et al. 2017) . It differs most clearly from known Vestalis larvae by having relatively much longer acuminate caudal gills (Fig. 49), the laterals about half the length of the remainder of the body, and in lacking the small antennomere between pedicel and scape (Fig. 37), the prementum is somewhat less incised but it is unclear how reliable this character is, especially given the known variation in Vestalis; the other caveat is that other Vestalaria species may exhibit unexpected characters.
