Benthocometes
Goode & Bean, 1896
Type
species.
Neobythites robustus
Goode & Bean, 1886
by subsequent selection by
Jordan
& Evermann 1896: 2514.
Type
locality: off Moro Castle,
Cuba
.
Diagnosis.
Body robust with a short, stubby head and terminal mouth; lateral line not reaching base of caudal fin; 4–10 predorsal pterygiophores; head and body covered with small, overlapping scales; eyes equal to or greater than length of snout; two posteriorly directed spines on opercle; one basibranchial tooth patch; vomerine tooth patch lacking lateral extensions; anterior gill arch with 3–12 long rakers; pseudobranchial filaments 5–8; pectoral fin rays 27–33; pelvic fins each with two rays. Owing to the discovery of the new species the diagnosis differs somewhat from that given by
Nielsen
et al.
(1999
:59).
Similarity.
The combination of two opercular spines, few long gill rakers (3–12), many pseudobranchial filaments (6–8), 4–10 predorsal pterygiophores, a blunt snout and diameter of eye larger than or equal to length of snout makes
Benthocometes
a unique ophidiine genus. A DNA-based analysis has not been undertaken.
Species.
Two species of
Benthocometes
are recognized:
B. australiensis
(here described)
B. robustus
(
Goode & Bean, 1886
)
A third nominal species
Benthocometes claudi
Torre
y
Huerta, 1930
belongs to the bythitid genus
Grammonus
Gill
in
Goode & Bean, 1896
(
Cohen 1964

Nielsen
