Eulodrobia Ponder, Zhang, Hallan & Shea, 2019

Diagnostic features

Members of this genus have a very diverse shell morphology, although it is never high-spired. The operculum is oval to circular, usually colourless to yellowish-brown or in a few species, brownish. 

The prostate gland is mostly visceral, and the penis often bears a distal lobe and, in this respect, resembles that of species of Fluviopupa Pilsbry, 1911 (Haase et al. 2006; Ponder & Shea 2014).

The coiled oviduct has, uniquely,  the initial loop pointed anteriorly and then it extends posteriorly, making an oval loop not seen in other Queensland spring taxa. Also, uniquely, when the seminal receptacle is present, it lies within this loop. Unlike several other Queensland spring tateids, the pallial oviduct lacks any significant elaboration of the ventral channel or genital opening.
