|Identification||Kryptopterus geminus,together with K. cryptopterus, can be distinguished from congeners by the dorsal profile lacking anuchal concavity and short maxillary barbels extending to the base of the pectoral fin. Kryptopterus geminus can be further distinguished from K. cryptopterus in having a narrower head (9.5–12.0% SL vs. 12.2–14.2), longer anal fin (62.2–72.7% SL vs. 57.2–62.9) and snout (39.5–45.3%HL vs. 35.1–39.8), and more laterally-placed eyes (only ventral half, vs. ventral two-thirds, of the orbital margin visible when the head is viewed ventrally).|
|Distribution||Known from the Mekong (from the mouth upriver to Vientiane), Mae Khlong (the mouth to at least Kanchanaburi), Bang Pakong (from the mouth to at least Prachinburi) and Chao Phraya River (the mouth upriver to at least Ayutthaya) drainages in mainland Southeast Asia.
