Nithyanandan, 21.10.2014 ; 4 males , 2 females ( NHMUK 2015. 3258–3263) tunicates collected by diving and removing tunicates attached to concrete sides of north tidal gate in phase A3 Sea City, D.K. Raja, 20.4.2014 . Etymology. Named for the shape of the male gnathopod 2 that superficially resembles that of some members of the genus Jassa (Ischyroceridae) . Description. Based on male holotype 4.3 mm . Head. Head elongate, lateral cephalic lobes strongly produced, rounded; eye lageniform. Mandible palp article 3 shorter than 2, spatulate with long distal setae. Maxilla 1 inner plate with setae along entire margin. Maxilla 2 with oblique setal row. Labium mandibular projections acute. Maxilliped palp elongate, second article extending beyond distal end of outer plate. Antenna 1 about half body length, peduncular article 2 a little longer than 1; primary flagellum subequal with peduncle, with 12 articles; accessory flagellum long with 5 articles. Antenna 2 unknown. Pereon. Gnathopod 1 coxa subsquare, weakly produced forward; basis enlarged, weakly excavated for reception of carpus when folded; carpus moderate, longer than broad; propodus longer than carpus, subrectangular, palm excavate, with blunt posterodistal spine. Gnathopod 2 coxa subrectangular; basis stout, excavated for reception of carpus when folded, strongly setose on anterior margin; carpus very short, cup-shaped; propodus grossly enlarged widening distally, with one strong posterodistal spine and one strong medial spine, anterior margin strongly setose; dactylus enlarged, overlapping palm. Pereopods 3–4 of normal Latigammaropsis form, dactylus short, much less than half length of propodus. Pereopod 5 basis moderately expanded. Pereopods 6–7 missing. Pleon. Uropod 1 peduncle with long, distal, interramal spine, half length of peduncle; inner ramus subequal with peduncle, outer ramus shorter than inner. Uropod 2 lacking interramal spine, peduncle shorter than rami, inner ramus a little longer than outer. Uropod 3 peduncle longer than broad; rami subequal, shorter than peduncle. Telson with each dorsolateral crest bearing a pair of robust setae Female (sexually dimorphic characters). Gnathopod 1 propodus longer than carpus, subovoid, palm oblique; dactylus fitting palm. Gnathopod 2 basis relatively slender; carpus short, cup-shaped; propodus subround with small posterodistal spine, palm evenly rounded; dactylus fitting palm. Remarks. Latigammaropsis pseudojassa sp. nov. shows no close relationship with any described species of the genus. The shape of the male gnathopod 2 is unique. Distribution. Kuwait .
