مفاتيح التعريف | الوصف الخارجي | قياسات المظهر الخارجي
الأشواك الظهرية (المجموع) : 34; الأشعة الظهرية الناعمة (المجموع) : 48 - 56; أشعه شرجية لينه: 46 - 60; فقرات: 79 - 80. Distinguished from all other Mastacembelus (sensu Travers) by substantially lower counts of dorsal and anal fin rays and vertebrae. The dorsal rays only 48-56 and anal fin rays only 46-60 (other Mastacembelus with dorsal and anal rays usually 70 or more). Vertebrae 79-80 (others species usually with 85 or more). The caudal fin rays count 21-22 is high (Mastacembelus alboguttatus, M. dayi and M. unicolor are the only other species with as many or more caudal fin rays. Snout very broad and short; jaws extending posteriorly fully two-thirds of distance to below anterior margin of eye; preorbital spine extending posteriorly to below margin of eye or somewhat beyond; preopercle without spines; body with a few large dark spots which may extend onto base of dorsal fin, fins otherwise plain (Ref. 39392).
