Material examined. 1♂, KSA: Jazan (Farasan Islands, Park 2), 16.715789N 42.080407E, 5. iii. 2017, sweep net, leg. Usama M. Abul El-Ghiet & Tarek M. El-Sheikh. Remarks. In the present study, the subfamily Gnamptodontinae is recorded for the first time for the Arabian Peninsula from Farasan Islands (Jazan, Kingdom of Saudi Arabia). The specimen does not agree with any of the Afrotropical species included in van Achterberg’s key (1983), or those of Fischer’s (1987). However, because of the bad condition of the specimen, we have refrained from allocating a species name until more specimens are collected.
