discussion
Remarks. Leptalpheus denticulatus, a relatively widespread infaunal shrimp, is recorded from Indonesia for the first time. This species appears to be the most common infaunal alpheid in shallow bays of Lombok, which are dominated by sand-mud and seagrass (e. g., Teluk Medana, Sira, Teluk Sekotong). In Teluk Medana, one specimen was found together with its presumed burrowing host, the callianassid mud-shrimp, Glypturus armatus, which is also known to host Jengalpheops rufus (see above).
distribution
Distribution. Indo-West Pacific: Vietnam, Philippines, Indonesia (new record), Fiji, French Polynesia (Anker & Marin 2009; Anker 2010; present study).
