Pteronemacheilus nov. gen.
Pteronemacheilus lucidorsum nov. sp.


Abstract

Schistura callidora, new species, is described from the Myitnge River drainage, Irrawaddy basin (Myanmar). It is distinguished by dark bars on the body much thinner in the anterior half of the body than in the posterior half; a high dorsal crest on the caudal peduncle; 81/2-101/2 branched dorsal-fin rays; and the lateral line reaching behind the base of the anal fin. Pteronemacheilus, new genus, is characterised by the presence of elongated skinfolds onthe dorsal side of the second and third branched pectoral-fin rays in males. Pteronemacheilus lucidorsum, new species, is described from the Myitnge River drainage, Irrawaddy basin (Myanmar). It differs from its only congener, P. meridionalis, by having the dorsal midline without pigmentation and usually 8 + 8 branched caudal-fin rays.
