  Remark
:
Fishes of the family Gasteropelecidae have the following characteristics: Frontal bone longitudinally corrugated, bearing a strong longitudinal ridge. Posttemporal and supracleithrum are fused into a single bone. The pelvic fins and associated bones are minute. They have an enlarged, strongly convex muscular pectoral girdle region, consisting of greatly expanded coracoids fused to a single fan-shaped and corrugated median bone. Their lateral line extends ventroposteriorly to approach the anterior termination of the anal fin, or they have 0 to 2 or 3 scales behind head and one or a very few scales on tail-fin base. Dorsal fin has 10 to 17 rays. Anal fin has 22 to 44 rays. An adipose fin is present in the larger species, but absent in the smaller species. All are capable of jumping relatively long or high distances by use of their modified, elongate pectoral fin rays and heavily-muscled, enlarged pectoral girdle. See Wiest, 1995 and Weitzman and Palmer, 1996 for discussions of their jumping abilities. Freshwater hatchetfish are found in Panama and all countries of South America except Chile. The family consists of three genera and nine species, ranging in standard length from 21.5 - 68 mm. Central America contains only one species, Gasteropelecus maculatus. South America contains species in three genera: Carnegiella, Gasteropelecus, and Thoracocharax. The species of the genera Gasteropelecus and Thoracocharax occur in open waters of larger rivers and streams and lakes, whereas species of Carnegiella occur in small creeks and streams (personal observations). Morphology and function of some of the smaller members of this family have been well studied (Weitzman, 1954 and Wiest, 1995), but the larger species, especially in Thoracocharax, have not been subject to such investigations. Most species probably have been described; however species problems associated with comparisons of population samples from different localities may reveal some new species. Members of this family are commercially collected for the aquarium trade.

Species/Synonymy list for the family Gasteropelecidae as currently in FishBase

Important recommendation:

The list below must not be used as an authority reference synonymy list like those found in scientific published revisions, which must be the source to be used and cited eventually when they exist.

Rather, it reflects the current content of FishBase, and the progress with respect to synchronization with the Catalog of Fishes. However, we think it can be useful for users to assess the quality of information in FishBase, to start new work on the family, or to cross-check with other lists.

But we appreciate to be cited in publications when this list has been of any working value. In particular, for published scientific, we suggest then to cite it in the Material and Method section as a useful tool to conduct the research, but again, not as a taxonomic or nomenclatural authority reference.

Unless it is explicitly precised, the list is not complete, please search all original names published for the family in the Catalog of Fishes (genera, species), including those with uncertain or unknown status, that are not included in FishBase when they are not attached to a valid species.

This list uses some data from Catalog of Fishes (not shown but used to sort names).

In the column CofF, the digit indicates the status of synchronization with CofF: 0: Not checked; 1: Same status;   2: Different status;   3: Other combination;   4: Synonym in CofF;   5: Species/Subspecies issue;   6: Synonym of another species in CofF;   7: Not in CofF;   8: Should not be in CofF. The CofF version currently used is the one published on 15-11-2013 (Ref. 94485).
