Harpiosquilla indica

HOLOTYPE.—1 ♂ , 150 mm; 10 miles due south of Mandapam Camp, South India; 12 fms; otter trawl; L. P. Woods on Norwegian trawler M–2; Sta. LW-20 (GA 64–7); II0E; 14 February 1964; SI Crust. 125717.

DIAGNOSIS.—Size moderate, male with adult characters at TL 150 mm; antennular peduncle shorter than carapace; corneal index 290; rostral plate (Figure 40) longer than broad, lateral margins tapering to slender median projection; carapace with median carina; upper margin of propodus of claw with smaller spines and denticles between largest spines; dactylus of claw with 9 teeth, outer margin with prominent angular projection in adult male; fifth thoracic somite rounded laterally (Figure 42); posterior 3 thoracic somites lacking submedian carinae; intermediate carinae of thoracic somites unarmed; ventral keel of eighth thoracic somite rounded; first to fifth abdominal somites lacking submedian carinae, abdominal carinae

spined as follows: submedian 6, intermediate 3–6, lateral 1–6, marginal 1–5; denticles 5, 11, 1; marginal carina of telson not more than 1.5 times as long as carina of lateral tooth; postanal keel short, not extending halfway between anus and posterior margin; at most inner half of distal segment of uropodal exopod dark.

COLOR.—Inner and outer surfaces of antennular peduncles lined with dark pigment; antennal scale outlined with dark chromatophores; dark transverse bar present dorsally between antennular and ophthalmic somites; rostral plate outlined with dark pigment, basal portion of plate with oval ring of dark chromatophores; margins, carinae, and grooves of carapace outlined with dark pigment; meral depression of claw with proximal and distal dark spots; posterior 3 thoracic

and all abdominal somites with dark posterior line and intermediate carinae lined with dark pigment; submedian area of thoracic and abdominal somites with diffuse dark pigment; telson with marginal carinae and dorsal pits darker than remaining surface; ventral surface of telson with bases of teeth and submedian distal area darker than remainder of surface; anterior edge of basal segment and proximal segment of uropodal exopod with diffuse dark spot; distal fourth of proximal segment of uropodal exopod with diffuse dark pigment, inner half of distal segment black; distal half of endopod dark with apex lighter along midline. The overall color pattern is shown in Figure 39.

SIZE.—Only specimen known, the male holotype, TL 150 mm. Other measurements (in mm): carapace length 30.5; cornea width 10.5; antennular peduncle length 27.0; rostral plate length 6.8, width 5.4; raptorial propodus length 39.4; fifth abdominal somite width 33.0; telson length 29.6, width 28.0.
