Barbodes sellifer
(Saddle Barb) was described as a new species in 2021 (Kottelat & Lim, 2021);
formerly it was considered to be part of Barbodes banksi from western Borneo.
The holotype (i.e the type specimen) was acquired in 1990 from freshwater
swamp forest in Singapore.
This species occurs in the
Malay Peninsula from Penang Island in the north to Singapore in the south.
It also occurs in Indonesia, in the Riau, Anambas and Natuna island groups
and central Sumatra (Riau province).
In the field adults are identified by a large, dark, triangular to
rectangular patch below the dorsal fin; sometimes smaller dark patches
can be discerned (one on the flanks above the anal fin and another at
the base of the tail). Juveniles have 3-5 spots on the flanks.
Its body colour is silvery to brownish, and the dorsal, anal and caudal
(tail) fin are reddish.
Barbodes sellifer typically inhabits unpolluted, well shaded, forest streams
and freshwater swamp forest, where it may occur in large shoals of tens of
individuals, sometimes mixed with Barbodes
lateristriga (Spanner Barb) and
Rasbora elegans (Two-spot Rasbora).
The distinctive dark patch is larger than that of
Barbodes rhombeus
(Indochinese Spotted Barb), a species that has been introduced in parts of
the Malay Peninsula
(including some rural and/or concretised streams in Singapore).

Fig 4 : Barbodes sellifer often swims in mixed shoals with other
barbs;
in Singapore mixed shoals with Barbodes
lateristriga
(Spanner Barb) are sometimes seen.
