A. López-Arbarello et al. 2010As for type and only species Neochallaia tellecheai; Small, fusiform actinopterygian with slender body; head length about 0.3 of SL (length from the tip of the snout to the base of the caudal fin at the hinge line); body depth about 0.3 of SL; skull roof bones ornamented with small tubercles; dorsal fin placed at the middle of the body; pelvic fin origin slightly anterior to dorsal fin origin;
caudal fin strongly heterocercal, the dorsal lobe being longer than the ventral lobe; fin rays evenly segmented except for a slightly longer basal segment, and branched only very distally; the lateral line extends enclosed in tubular scales in the body lobe of the tail and, at least for a short span onto the fin web; body completely covered with small and numerous ganoid scales, with smooth surface and finely pectinate posterior border; scales on the body lobe with long and sharp posterodorsally directed posteroventral process; a series of large lanceolate dorsal median scutes preceding the
caudal fin, which are ornamented with delicate ridges emerging latero-posteriorly from a main median ridge.
