D90F8788FFB5B041FF23FA23407CFE2D.taxon	diagnosis	Diagnosis: Rostrum is short and distinctly cloven microscopically. The carapace is not glabrous bearing minute bristles; carapace carinated with 7 (2 + 5) teeth and anteriorly interrupted with hepatic sulcus, lateral carina III armed 1 - teeth or tubercles. The branchiostegal spine is largely extended to the middle of the antennal scale and directed anteriolaterally. The antennal spine is small, pterygostomian spine little large and appears at an equal level of the branchiostegal spine. Antennal scale length is longer than the width (1.6 times) with anterio-lateral spine. Pereopod V of spawning females is a simple form. Generally, abdominal segments are sculptured, abdominal tergum I bearing a pair of dorsal spines directed anteriorly, tergum II interrupted with a dorsal spine, while tergum III and IV dorsally sculptured with a box shape, tergum V having two pairs of dorsolateral spines while 3 pairs were present in tergum VI, all the pleura acute ventrally. Telson is equal to uropods. Coloration: Muddy brown	en	Purushothaman, P., Chakraborty, Rekha Devi, Kuberan, G., Maheswarudu, G.

D90F8788FFB5B041FF23FA23407CFE2D.taxon	discussion	Remarks: The present specimens agree with the original descriptions and keys by Alcock (1901) and Chan (1996). Even though, the tubercles on the dorsal side of abdomen III are not round, but only appear as a small dot. Few P. affinis affinis individuals were noticed during September to December among the deep sea landings which included Heterocarpus sp. The fecundity was observed as 400 - 500 eggs per female (egg size range: 0.5 – 0.6 mm), which was comparatively lesser than to any other caridean shrimp. Previously, this species was recorded from various locations along the Indian coast (Bombay, & Bay of Bengal) and Madagascar at depths of 33 – 175 m (Sankolli & Shenoy 1979; Chan 1996; Radhakrishnan et al. 2011). But, in the present study it is obtained from Quilon bank at 250 – 300 m, indicating that P. affinis affinis has a wide depth distribution along the Indian Ocean.	en	Purushothaman, P., Chakraborty, Rekha Devi, Kuberan, G., Maheswarudu, G.

D90F8788FFB4B042FF23F99947BBFD13.taxon	diagnosis	Diagnosis: Rostrum is short and vividly cloven. The carapace is pubescent; length of the carapace 1.13 times as long as wide; dorsally carinated with 7 – 9 teeth. Lateral carina I bearing 8 – 9 teeth, lateral carina II carinated with 7 (2 + 5) teeth and anteriorly interrupted with hepatic sulcus, lateral carina III armed with 10 – 12 teeth or tubercles. The branchiostegal spine is small extended to the end of 1 st antennular peduncle and directed anterio-laterally. The antennal spine is small, pterygostomian spine little large and appears at an equal level of the branchiostegal spine. Antennal scale length is longer than the width (1.6 times) with anterio-lateral spine. Abdominal segments are carving distinctly subdivided, segment 1 bearing a pair dorsal spine directed anteriorly, segments II and III having continues lateral ridges, segments dorsally armed with strong posteromedian spine, segment V not having the dorsal spine, somite VI was found to bear three pairs of dorsolateral spines. Abdominal pleura with ventral margins were rounded bluntly. Coloration: Body generally muddy brown with transverse pale bands present on the mid-carapace and tail-fan.	en	Purushothaman, P., Chakraborty, Rekha Devi, Kuberan, G., Maheswarudu, G.

D90F8788FFB4B042FF23F99947BBFD13.taxon	discussion	Remarks: In this study, specimens agreed with the descriptions of Alcock (1901) and Chan (1996). Chan (1996) found the largest female CL 12.4 mm, smallest spawning female CL 11.3 mm and largest male CL 10.7 mm from the Andaman Sea, Philippines, Indonesia, New Caledonia, Chesterfield and Loyalty Islands at the depths of 100 – 525 m. Similarly in the present study, two non-ovigerous female specimens were noticed at depth of 250 – 300 m in continental slope of southeastern Arabian Sea, first pereopod is not chelated. Also, we noticed that carpal length of second pereopod is sub-equal to the length of the chela. Mitochondrial genes sequencing: Three 16 S sequences and two COI sequences of P. affinis affinis and two 16 S sequences of P. propensalata were submitted to GenBank (accession numbers: MF 996919 – 25). 4.1 % of genetic divergence between the 16 S DNA sequences of the two species was observed.	en	Purushothaman, P., Chakraborty, Rekha Devi, Kuberan, G., Maheswarudu, G.
