Syncrossus Blyth
Syncrossus Blyth, 1860
(type species:
Syncrossus berdmorei Blyth, 1860
, by subsequent designation by Jordan, 1919b). Gender masculine.
Diagnosis. Distinguished from all other genera of Botiinae by the unique presence of a sickle-shaped anterior process of the premaxilla, surrounding a cavity between left and right processes; rostral process short, without ridge along inner edge.
Distinguished from other lineages within the subfamily Botiinae by the following combination of characters: Mental lobe not developed in a barbel, with a pair of fleshy papillae at its anterior edge. Fronto-parietal fontanelle large, wide. Anterior chamber of gas bladder partly covered by bony capsule; posterior chamber large. Top of supraethmoid narrow. Optic foramen large. Suborbital spine not strongly curved backwards, bifid. Head naked (based on Taki, 1972: 74, 76). Colour pattern: regular, narrow bars throughout life, in some species with overimposed longitudinal rows of black spots.
Remarks. The valid name for the lineage called
Hymenophysa
by Fang (1936), Nalbant(1963, 2002), Taki (1972) and others is
Syncrossus Blyth, 1860
. Blyth (1860: 166) originally included two species in his
Syncrossus
,
S. berdmorei Blyth, 1860
and "
Schistura grandis
apud McClelland". The last name is a deliberate application of a previous misidentification[ICZN art. 67.2.1], and therefore two species are included. The type species, by subsequent designation by Jordan (1919b: 294) is
S. berdmorei
.
The species called
B. hymenophysa
by Taki (1972) is
B. helodes
(see Kottelat, 1984; Nalbant & Bianco, 1984).
Included species:
Syncrossus beauforti (Smith, 1931)
(synonyms:
B. lucasbahi Fowler, 1937
,
B. beauforti formosa Pellegrin & Fang, 1940
