Diagnosis

A genus of miniature fishes (less than 20 mm SL) distinguished from other aspredinids by the following characters: presence of a dorsal spinelet and rigid dorsal-spine; anteriorly expanded supraoccipital; absence of a posterior cranial fontanel; posterior cartilage of palatine absent; 2 pectoral radials; horizontal bony lamina developed only on last three centra and compound ural centrum; and absence of procurrent caudal-fin rays. Other characters not unique to this taxon but useful for identification are: reduced ornamentation of skull roof, dorsal lamina of Weberian complex, and nuchal plates; jaws equal; pectoral fin with spine and 4 rays; dorsal fin with spine and 3 rays; dorsal- and anal-fin membranes not adnate with body; dorsal- and ventral-most principal caudal rays much shorter than others, infraorbital lateralis canal truncated; lateral line truncated at approximately the level of the dorsal fin origin.'; TOPICSORDER 999 1 1001 1003 ; OPTIONS WRITEASLIST SQUARECORNERS NOFOOTPARENTHESES FEETINTREE UNDERCONSTRUCTION UPARROWS DEFRANDICON CenterBranches WRITETXPINTT EXCLUDETOLQUERY BREAKAFTERTITLE WRITENEXTPREV USENEXTPREV LEAFPAGE NUMRANDPICTURES=6 BRANCHHEIGHT=3 INCERTAEEDGEGAP=5 INCERTAETIPLENGTH=6 TAXONSPACING=1; END; BEGIN NOTES; TEXT TAXON=1 TEXT= Friel_1995; END; BEGIN MACCLADE; Version m.1; LastModified -1224947071; Singles 1000&/00; FileSettings editor ; Editor 010011 24 Geneva 9 204 1; TaxStatus closed Geneva 9 U ; CharStatus closed Geneva 9 U ; NodeStatus closed Geneva 9 U ; TreeStatus closed Geneva 9 U ; TypeStatus closed Geneva 9 U ; END;
