(Fig. 4a) is instantly recognizable by its long, drawn-out tegmen (Fig. 2a, e) that extends up to the base of the gonostyles. It also has a characteristic set of megasetae-like bristles (3-4) that are bunched together and slotted into the underside/ventral part of the hollow apical tooth which is reminiscent of an upturned canoe (Figs 2b, 3b, c). On one of the paratypes we examined, the ventromesial sclerotization of the gonostylus was ruptured (Fig. 2b). This forced the megasetae-like bristles out from the sheath-like tooth that normally houses the bristles (Fig. 3b, c). When viewed with a fibre-optic lamp or otherwise, these setae may be visible within the tooth giving the illusion of surface topography/texture on the tooth.

can be separated from most similar looking species by the absence of long specialized setae and megasetae on the inner-sides of the gonostyles.

However the absence of long specialized setae at the inner side of the gonostyles isolates this species from all other potential congeners. Given the small size and the absence of recognizable characters, additional genetic characters will be helpful to correctly position
