Distinguished from all congeners in possessing one series of middle abdominal plates between the lateral abdominal plates (vs. middle abdominal plates absent in remaining species). Differs from Acestridium dichromum (the most similar species) in having a small and rounded snout-tip spatulate projection (vs. large and oval spatulate projection), a thick pectoral-fin spine without serrae or slightly serrated (vs. very thick and strongly serrated in the inner face), posterior most lateral abdominal plate small (vs. large), and preanal plate approximately rectangular, with short lateral projections (vs. preanal plate cross-shaped, with large lateral projections) (Ref. 75792). Description: D i+7; A i+5; P I,6; V i+5 (Ref. 75792). |
