Subspecies 
Common NamesE: Aru Mangrove Snake 
SynonymMyron karnsi MURPHY 2011
Myron richardsoni — DE ROOIJ 1917: 192
Myron karnsi — MURPHY & VORIS 2014: 29
Myron karnsi — WALLACH et al. 2014: 466 
DistributionIndonesia (Aru, Kobroor, Selrutti islands)

Type Locality: Indonesia Aru, Kobroor, Selrutti (about 5°46'S and 134°31'E).  
Reproductionviviparous (manual imputation, fide Zimin et al. 2022) 
TypesHolotype: SMF 19569. 
DiagnosisDiagnosis: A melanistic species with 21 scale rows at mid body; a semi-divided nasal scale; the third pair of chin shields are as wide as they are long; all of which will distinguish it from the other new species described here. The black coloration, narrow yellow cross bands, enlarged occipital scales posterior and lateral to the parietals, and keeled scales starting on row 3 (as opposed to row 5 or 6) will separate it from M. richardsonii (Murphy 2011). 
CommentApparently only known from the holotype. 
EtymologyThis species is named in honour of Daryl R. Karns (1949-2011), Hanover College and the Division of Amphibians and Reptiles, Field Museum of Natural History for his contributions to herpetological research and work with homalopsid snakes. Tragically, Daryl’s untimely death occurred before he could learn that a homalopsid snake species new to science was being described in his honor.
