📖 Overview

Found mostly in large rivers with muddy bottom, turbid water and slow to moderate current. Caught by seine and push net. In all habitats where it was collected by push-net, it was only present at depths greater than 1 meter, usually at a depth immediately below those at which a slight drop in temperature could be felt. Located above the bottom, usually above a layer of 10-20 cm loose ooze.

🐟 Physical Description

Dorsal soft rays (total): 12 - 15; Anal soft rays: 16 - 20; Vertebrae: 38 - 42. Differs from all except S. praecox in having vomerine tooth plates (versus missing), more maxillary teeth (30, versus 12-19), 1-3 teeth on caudal end of basibranchial 1-2 in most specimens (versus missing), a completely ringed proximal end of epibranchial 3 surrounding third efferent branchial artery (versus partially encircled), and in lacking in midventral row of melanophores (versus presence). Differs from S. malleti in lacking a basipterygium pigment ring (versus presence). Differs from S. praecox in having several (3-5) prepectoral melanophores (versus missing), more vertebrae (38-42, versus 37-38) and no palatine teeth (versus presence). Differs from all other Sundasalangidae (except S. praecox and S. malleti) in lacking a cardiac chamber pigmentation (versus presence). Also differs from all congeners in having a dermethmoid, supraorbitals, hyomandibulars, autopterotics, exoccipitals, basioccipital and ventral hypohyals (versus these bones not ossified), more gill rakers on branchial arches (10-16 on first arch [versus 2-9], 9-11 on second and third arches, 7-9 anteriorly and 6-8 posteriorly on fourth arch, 6-7 on fifth arch).: elongated.
