Rhinoglena n.sp.1 has been found in two temporary ponds in Texas and New
Mexico. The animal is diagnosed by its ovipary, its relatively large
rostrum and trophi and toe morphology. Whereas other members of the genus
Rhinoglena are strictly cold-water inhabitants, Rhinoglena n.sp.1 occurs in
warm-water, temporary desert ponds. The type locality is a low lying
depression in Eastwood City Park (Album Park, El Paso County, TX). The
second pond is located along New Mexico State Road 404 (Anthony Gap) in
Doña Ana County. Both of these ponds are dry most of the year, filling
after seasonal rains. The water temperatures can exceed 30C. Rhinoglena
n.sp.1 carries its eggs rather retaining them within the females as in
other rhinoglenids.
