Fishes of the family Gobiidae, with an incredible diversity of over 2,000 species across 250 genera, represent one of the most diverse groups of vertebrates. The subfamily Sicydiinae is a speciose group of gobies that occupy tropical to temperate island streams in Indo-Pacific regions. Within this subfamily, the genus Sicyopus Gill, 1863, consists of eight valid species. This genus can be recognised by possessing widely spaced, mostly recurved, conical teeth on both the premaxillary and dentary jaws. Additionally, the premaxillary ascending process is narrowly tipped dorsally, and the tongue is free from the mouth floor. Recent ichthyofaunal surveys conducted in the streams of western Sumatra resulted in the collection of several specimens belonging to two distinct Sicyopus species. These findings represent novel records and significant range extensions for Sicyopus spp. within the Indonesian archipelago. Brief descriptions of the two newly recorded species based on the current collected specimens, as well as morphological character comparisons, are presented in this study..
