The purpose of this study were to know the distribution of Nomorhamphus genus in Southeastern Sulawesi and to examine the first record of Nomorhamphus sp. in Loea river east Kolaka Regency Southeast Sulawesi Indonesia. Nomorhamphus is as one of Sulawesi’s endemic fish. The distribution map of Nomorhamphus based on primary and secondary data. Both visualized using System Information Geography (SIG) through QGIS application. First record of Nomorhamphus sp. in Loea river describe by morphometric and meristic data. Nomorhamphus sp. catched by used a beach seine. Each individual caught was put into a plastic sample which was given formalin about 4%. This study recorded the fiftythree specimen consist of twentytwo males and thirtyone females. Several locations are known as the Nomorhamphus sp. habitat, namely Fotuno fountain, Moramo waterfall, Balano fountain, Laweau river, Moramo river, Anduna river and Asinua river. Furthermore, other Nomorhamphus found in Wawolambo river ( N. lanceolatus ) and Mangolo river ( N. sagittarius ). Several characters of male and female of present study including total length, standard length and head length about 30.0-87.7 mm, 24.2-70.5 mm and 7.3-30.7 mm, respectively. The meristic showed both males and females have relatively the same number of fin rays. The relationship between total length and body weight of male and female followed the equation W = 0.0385L 1.1355 (r = 0.90664) and W = 0.0647L 2.2221 (r = 0.87756), respectively.
