简单描述
型态特徵 | 形态测量图
背的软条 (总数): 12-15; 臀鳍软条: 16 - 20; 脊椎骨: 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).
有别于全部除了 S.之外早发的 有犁骨齿板 (对不见的), 更多的上颚齿 (30, 对 12-19),1-3 牙齿在尾部末端基鳃骨 1-2 在大多数的标本 (对不见的), 一完全地有环近侧端上鳃骨 3 围住第三个输出的鳃动脉 (对部份地环绕), 与在没有黑色素细胞的腹部中央列.(对出现) 有别于 S. malleti 在没有鳍基软骨有颜色环.(对出现) 有别于 S. 早发的 有一些 (3-5) prepectoral 黑色素细胞 (对不见的) ，更多的脊椎骨 (38-42, 对 37-38) 与没有颚齿.(对出现) 有别于所有的其他 Sundasalangidae(除了 S. 以外早发的 与 S. malleti) 在没有心脏的腔室颜色.(对出现) 在有一个方面也有别于所有的同类 dermethmoid, 眶上的, hyomandibulars ， autopterotics ，外枕骨，基枕骨与腹面 hypohyals(对不被钙化的这些硬骨), 在鳃弓上的更多的鳃耙.(10-16 在第一鳃弓上 [对 29] 的,9-11 在第二个与第三个弓上,7-9 前面地与 6-8 在第四个弓后面,6-7 在第五个弓上)
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.
用泥底部, 浑浊的水与缓慢到中等的水流大部分配现于大河了。 被曳网与推网捕获了。 在所有的栖息地在哪里它被由推网收集, 它是只出现在深度大于 1 公尺, 通常在深度紧邻那些下方在那一个在温度的轻微的下降可能是毛毡。 位于底部上面了, 通常在 10- 的层 20 公分松散的软泥之上。
