no. 3641 STOMATOPOD CRUSTACEA — MANNING 53 



absent; accessory medians not fusing with median to form anchor; 

 anterior submedians slender, with apical tubercle; an irregular U- 

 shaped ridge, open anteriorly, extends posteriorly from midlength 

 of telson between anterior submedian and intermediate carinae, 

 across central carinae, to equivalent point on other side of telson; 

 carinae of marginal teeth sharp, submedians divergent anteriorly; 

 numerous small submedian denticles present; 2 intermediate denticles 

 present, each sharp, anteriorly recessed; ventral surface of telson 

 lacking sharp longitudinal carinae. 



Endopod and expopod of uropod with normal complement of setae, 

 some distal setae of endopod erect; endopod slender, tapered distally, 

 with long dorsal carinae; proximal segment of exopod with slender, 

 ventrodistal spine at articulation of distal segment; inner spine of 

 basal prolongation shorter than outer. 



Color. — Body light, with traces of darker pigment on dorsum; 

 carapace, sixth thoracic somite, and first abdominal somite each with 

 dark dorsal patch; sixth thoracic somite dark laterally; merus of claw 

 with dark, dorsal patch. 



Size. — Females only examined, TL 17.8-22.9. Lanch ester's speci- 

 mens were all small, TL 7.5-17.5. Other measurements of female, 

 TL 22.9: carapace length 4.4; fifth abdominal somite width 3.1; 

 telson length 2.8, width 2.8. 



Discussion. — These two specimens correspond very closely with 

 the account of the species given by Lanchester (1903); the telson 

 ornamentation most closely resembles that recorded by Lanchester 

 as u segregatus b." 



Borradaile (1907) considers this species to be identical with G. 

 affinis de Man, 1902, from Ternate, a form described by de Man as a 

 variety of G. chiragra. Identification of G. segregatus with G. affinis 

 must await direct comparison of type material or adequate redescrip- 

 tion of both species based on type material. 



The specimens recorded herein are similar to G. choprai Manning, 

 1967b, described from specimens taken in the northwestern Indian 

 Ocean. Gondoactylus choprai, however, differs from all other species 

 in the genus in lacking a fixed distoventral spine on the proximal 

 segment of the uropodal exopod. 



Distribution. — Central and western Indian Ocean, from the 

 Comoro Islands, Madagascar, and from several localities in the 

 Maldive Islands (Lanchester, 1903); shallow water to 35 fms.
