Material examined. ZUTC Amph. 2402, six males, 15 females and three juveniles. Loc 2 (Djod, 25°27'00" N , 59°30'36"E ); AM P2007, 1 male . Remarks . Material in the present study agrees well with previously studied material by Guerra-García (2002c). There are three pairs of gills on pereonites 2–4 ( Fig. 15 ), pereopod 5 is 3-articulated ( Fig. 16 P5). The setal formula on the mandibular palp is 1+3+1 ( Fig. 16 RMd) and the inner and outer lobes on the lower lip are apically setose ( Fig. 16 LL). Both male and female gnathopod 2 bear three spines on the propodus palm ( Fig. 16 Gn2). The first and second antennal flagellums are five and bi-articulated ( Fig. 15 ). Pereopods 6 and 7 are six-articulated ( Fig. 15 P6-7). Material of Pseudocaprellina pambanensis was collected from filamentous algae only in one locality. Previous records of this species belong to Tanzanian coasts (Guerra-García 2002c), Indonesia (Krapp-Schickel & Guerra- García 2005) and Australia (Guerra-García 2004a). The monotypic genus Pseudocaprellina Sundra-Raj, 1927 was described based on two male specimens from the Gulf of Mannar, India . Later, a mature female was described from same area by Sivaprakasam (1977) in which the second gnathopod bears three grasping spines while Sundra-Raj specimens have two grasping spines. The material from the Gulf of Oman has three grasping spines similar to Sivaprakasam description. According to Guerra-García (2002c), these are possibly intraspecific variations. Also, in this study, some variations on their mouth parts were observed such as article 3 of mandibular palp with 1+3+1 setal formula instead of 1+2+1 and inner and outer lobs on lower lip are apically setose ( Fig. 16 ).
