DistributionNW Guatemala

Type locality: Todos Santos, Huehuetenango, Guatemala, 2438 m (8000 ft.) elevation.  
Reproductionoviparous 
TypesHolotype: UMMZ 89078 
DiagnosisDiagnosis (stadelmani): Dorsal scale rows 19, ven- trals 179-191 in females, dark brown or black stripe on scale row six, seven, or eight usually present; all surfaces of hemipenial base spinose, 12-16 maxillary teeth [from MENDELSON & KIZIRIAN 1995]. 
CommentSynonymy: Myers 1974 synonymized R. stadelmani with R. hempsteadae. He justified this with the observation that the holotype of hempsteadae is an adult male whereas the name Rhadinaea stadelmani is based on a juvenile female. MENDELSON & KIZIRIAN 1995 resurrected stadelmani for populations in the Sierrade los Cuchumatanes and Montafiasde Cuilco, in northwestern Guatemala. MYERS 2011 still doesn’t list stadelmani in his list of Rhadinella, so it’s status is still a bit unclear.

Similar species: Rhadinella hempsteadae. 
EtymologyNamed after Mrs.R.W. Hempstead of Cobain, Guatemala, in recognition of courtesies rendered to L.C. Stuart in the course of his investigations on the fauna of Alta Verapaz.

Etymology (stadelmani): named after the collector of the types, Raymond Stadelman.
