簡短描述
型態特徵 | 形態測量圖
背的軟條 (總數): 12-15; 臀鰭軟條: 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).
有別於全部除了 S.之外早發的 有犛骨齒板 (對不見的), 更多的上顎齒 (30, 對 12-19),1-3 牙齒在尾部末端基鰓骨 1-2 在大多數的標本 (對不見的), 一完全地有環近側端上鰓骨 3 圍住第三個輸出的鰓動脈 (對部份地環繞), 與在沒有黑色素細胞的腹部中央列.(對出現) 有別於 S. malleti 在沒有鰭基軟骨有顏色環.(對出現) 有別於 S. 早發的 有一些 (3-5) prepectoral 黑色素細胞 (對不見的) ，更多的脊椎骨 (38-42, 對 37-38) 與沒有顎齒.(對出現) 有別於所有的其他 Sundasalangidae(除了 S. 以外早發的 與 S. malleti) 在沒有心臟的腔室顏色.(對出現) 在有一個方面也有別於所有的同類 dermethmoid, 眶上的, hyomandibulars ， autopterotics ，外枕骨，基枕骨與腹面 hypohyals(對不被鈣化的這些硬骨), 在鰓弓上的更多的鰓耙.(10-16 在第一鰓弓上 [對 29] 的,9-11 在第二個與第三個弓上,7-9 前面地與 6-8 在第四個弓後面,6-7 在第五個弓上)
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, 混濁的水與緩慢到中等的水流大部分發現於大河了。 被曳網與推網捕獲了。 在所有的棲息地在那裡它被由推網收集, 它是只出現在深度大於 1 公尺, 通常在深度緊鄰那些下方在那一個在溫度的輕微的下降可能是毛氈。 位於底部上面了, 通常在 10- 的層 20 公分鬆散的軟泥之上。
