Common Names 
SynonymCeratophora karu PETHIYAGODA & MANAMENDRA-ARACHCHI 1998
Ceratophora karu — JANZEN et al. 2007 
DistributionSri Lanka (Ceylon)

Type locality: Morningside F.R. (near Rakwana), 1060 m elevaon (06°24'N, 80°38'E).  
TypesHolotype: BMNH 1996.445, male; paratypes: BMNH, NMSL (= WHT) 
DiagnosisDiagnosis: Ceratophora karu is distinguished from all other Ceratophora (except C. tennentii and C. aspera) by the rostral appendage being complex, comprising more scales than rostral scale alone (Fig. 22) (vs. rostral appendage restricted to rostral scale alone in C. erdeleni and C. stoddartii). It is distinguished from C. tennentii by the presence of prominent superciliary scales (vs. absent in C. tennentii) and from C. aspera by the absence of a palpable squamosal process (Fig. 30) (vs. squamosal process present (Fig. 10) in C. aspera). 
CommentC. karu is ground-dwelling and the only fast-moving lizard containing a rostrum composed of numerous pointed scales. The rostrum of C. karu lacks the fleshy protuberence characteristic of horned Ceratophora, however. 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 its original description (Meiri et al. 2017). 
EtymologyThe species name is a patronym commemorating the late Punchi Banda Karunaratne, mentor, guide and friend both to ourselves and so many other investigators of Sri Lanka's natural wealth, universally known to friends and colleagues simply as "Karu," which diminutive form we use here with respect and affection as a noun in apposition.
