摘要

摘要:在缅甸北部伊洛瓦底江流域中发现了一种名为Mystus celator sp. 11 .的植物。它与同类动物的区别在于:身体两侧有三个同样深的纵向条纹，由两个苍白的间隙隔开;鼓膜上又圆又黑的斑点;卵球形，在尾端花序梗上的黑点;脂肪鳍基部长度18.0 ~ 23.3% SL;前背轮廓角21-24°;后颅囟门未达枕上突底;第一鳃弓上有25-30个耙;35-36个椎骨。密斯图斯的身份是固定的指定一个典型。

Mystus celator, a new species of catfish from northern Myanmar (Actinopterygii: Siluriformes: Bagridae)

Abstract Mystus celator sp. nov. is described from the Irrawaddy River drainage in northern Myanmar. It can be distinguished from congeners in having a combination of: three equally dark longitudinal stripes separated by two pale interspaces on sides of body; round, dark tympanic spot; ovoid, dark spot on caudal peduncle; length of adipose-fin base 18.0–23.3% SL; angle of predorsal profile 21–24°; posterior cranial fontanelle not reaching base of supraoccipital process; 25–30 rakers on the first branchial arch; and 35–36 vertebrae. The identity of Mystus pulcher is fixed with the designation of a lectotype.
