TypesHolotype: UTA R-33051 
DiagnosisDiagnosis. Rhadinaea anachoreta can be distinguished from all other Hon­duran snakes, except Stenorrhina freminvillii, Rhadinaea decorata, R. kinkelini, R. lachrymans, R. tolpanorum, Urotheca decipiens, and U. guentheri, in having smooth dorsal scales in 17 rows throughout the body and a lineate dorsal pattern. Stenorrhina freminvillii has the internasal fused to the anterior section of the nasal and fewer than 50 subcaudals (versus internasal not fused to nasal and more than 60 subcaudals in R. anachoreta). All of those Rhadinaea species have two postoculars and all but an occasional R. decorata have 1+2 temporals (versus a single postocular and a single secondary temporal in R.anachoreta). Urotheca decipiens and U.guentheri have distinct pale lateral stripes, two postoculars, and a long, fragile, and proportionately thick tail with 82 or more Subcaudals when complete (versus pale stripes absent, a single postocular and a gradually tapering tail with fewer than 81 subcaudals in R. anachoreta) (McCranie 2011: 371). 
EtymologyThe specific name anachoreta is derived from the Greek anachoretes (meaning a hermit or recluse). The name was used in reference to "the disjunct, isolated distribution and secretive habits of this species" (E. Smith and Campbell, 1994:6).
