Material examined. Saudi Arabia: 1 female (pocl 3.0 mm), Red Sea coast, Al Lith, sta. SAFA-039, 20 ° 16.72 ’N, 40 ° 22.33 ’E, silt-sand flat with coral rubble, near small young mangrove, 1–2 m, coll.

Description. See Komai & Anker (2010).

Colouration in life. Body and appendages whitish with pale orange-yellow tinge ( Fig. 8 View FIGURE 8 ).

Distribution. Indo-West Pacific: French Polynesia (Society Islands) ( Komai & Anker 2010; Anker 2014; present study) and Saudi Arabia (Red Sea coast) (present study).

Remarks. Naushonia serratipalma   was originally described based on a female holotype from Moorea, French Polynesia ( Komai & Anker 2010), with a subsequent record of another female specimen from the same locality in Anker (2014). The Saudi Arabian specimen, if confirmed to be conspecific with N. serratipalma   (see below), would represent a significant range extension of the species, with the geographic range possibly spanning the entire tropical Indo-West Pacific from the Red Sea to French Polynesia.

Among the species characterized by the non-carinate pleomeres and marginally unarmed pleura, N. serratipalma   is morphologically closest to N. latimana   , N. macginitiei   and N. perrieri   . The four species share the presence of less than 10 teeth on the lateral margin of the antennal scaphocerite, with the terminal tooth pointing straight-forwards, not incurved. However, N. serratipalma   can be distinguished from the other three species by the distinctly serrated proximal part of the occlusal margin of the cheliped palm vs. non-serrated in N. latimana   , N. macginitiei   and N. perrieri   (cf. Glassell 1938; Ngoc-Ho 1996; Komai & Anker 2010).

The topotypic specimen from Moorea generally agrees with the holotype, differing only in the slightly broader rostrum and weaker sculpture on the pleonal tergites (cf. Komai & Anker 2010). The apparently young specimen (cl 3.0 mm) from Saudi Arabia differs from the French Polynesian specimens in the relatively narrower rostrum with stronger marginal teeth ( Fig. 7 View FIGURE 7 A); the possession of two or three minute denticles, instead of only one denticle, on the lateral margin of the telson ( Fig. 7 View FIGURE 7 B); having no trace of sculpture on the pleonal tergites; and the relatively more slender cheliped palm (cf. Fig. 8 View FIGURE 8 A and Komai & Anker 2010: fig. 1 C). In all other diagnostic features, such as the proximal part of the occlusal margin of the cheliped palm serrated with small teeth ( Fig. 7 View FIGURE 7 C) and the antennal scaphocerite bearing five or six teeth on the lateral margin, including one straight terminal tooth ( Fig. 7 View FIGURE 7 A), the Saudi Arabian specimen agrees well with N. serratipalma   . Similar intraspecific variation in the shape and armature of the rostrum is known in N. carinata ( Dworschak et al. 2006)   and N. lactoalbida   (see above), whereas the number of denticles on the lateral margin of the telson is also variable in N. japonica   (see above).
