Bhart & Wachkoo (2013) provided As a result of extensive surveys during 2016–2017, keys to the Leptogenys in India with descriptons of two workers of the genus Leptogenys were collected from new species. Xu & He (2015) reviewed the Oriental diferent forest areas of Margalla Hills in Rawalpindi, species of this genus, provided an identfcaton key to Islamabad, Pakistan. Specimens of this species were the ant fauna in China, and described and added two found under rocks near leaf liter and were hand new records to the country. Other noteworthy studies collected. The collected specimens were placed in include that of Bolton (1975) and Latke (2011), which potassium cyanide killing jars.
