Ceratophora erdeleni — JANZEN et al. 2007 
DistributionSri Lanka (Ceylon)

Type locality: mountains in E Sinharaja Forest, Morningside, 1000-1300 m elevation.  
TypesHolotype: BMNH 1996.448, 
DiagnosisDiagnosis: Ceratophora erdeleni is distinguished from all other Ceratophora by having only a rudimentary rostral appendage (restricted to rostral scale alone) (Fig. 13) or lacking such an appendage altogether in both sexes, the appendage length (AL) when present is 8.7-17.3% of distance between anteriormost point of or­ bit and middle of nostril (EN) (vs. 20.0-225.6% in both sexes of C. stoddartii, the species most closely related to it (Fig. 38 in P & NA 1998)). 
Commentsubarboreal, has only a rudimentary or nonexistent rostral appendage and is
otherwise very similar morphologically to C. stoddartii. The ranges of C. erdeleni and C. karu overlap in the Morningside Forest Reserve.

Rare and critically endangered in Sri Lanka (BAHIR & SURASINGHE 2005).

Abundance: only known from the type locality (Meiri et al. 2017). 
EtymologyThe species name is a patronym honouring Walter Erdelen (Uni­ versity of Wurzburg, Germany), who in the course of extensive work in Sri Lanka in the 1980s was responsible for inspiring renewed interest in the herpetofauna of this island.
