3.2 Material examined (MSC)
Two males (CL = 17.42, 12.7 mm, CB = 16.26, 10.2 mm) and one female (CL = 16.9 mm, CB = 15.1 mm) were
collected from Al-Fao city, Rass-Al-Beshaa area, 29°69’N, 48°55’E, 5.5-25 m, catch by trawl net, at Nov. 10
th
,
2016.
3.3 Diagnosis
Carapace (Figure 2A) discoidal, convex; dorsal surface finely punctate on branchial, cardial and intestinal regions,
along branchio-cardiac grooves, and medially on gastric region.
Anterolateral and posterolateral border covered with larger to smaller granules; front crescentic shaped nearly
smooth; shallow anterior margin of efferent channel nearly straight, separated from lateral granulated margin by
narrow U-shaped incision. lower margin bearing line of prominent granules. Abdominal segments 3-6, Male
abdomen (Figure 2B) elongate-triangular; telson completely smooth.
Ischium of 3rd maxilliped slightly longer than merus, about 1.22 times merus length. Margins of fused male
abdominal segments 2-6 distally carinate. Margins of fused abdominal segments in female minutely granulate
(Figure 2C).
Chelipeds equal in size and shape; merus longer than total length of carapace, Male chelipeds (Figure 2A)
moderately long than female and long than carapace length about 2.5 times the carapace length, its surface
minutely granulate, anteriorly granulate.
Ambulatory legs are slender; merus longer than carpus and propodus; dactylus sharp tipped at distal end. First
male pleopod (Figure 2B) slender filamentous, tip setose, apical brush like plumose setae, setae on lateral sides;
distal end of base setose, bulge formed.
3.4 Remarks
Hiplyra sagitta
was described from the Persian Gulf by Galil (2009). The specimens in current study agree closely
with the specimens description in Galil (2009), with the anterior margin of efferent channel separated from lateral
margin by triangular incision.
H. sagitta
with largest size in the genus
Hiplyra
and the largest male recorded from
the Persian Gulf (CL = 16.04 mm, CB = 14.56 mm) and the largest female found in Kuwait from coast of the
Persian Gulf (CL = 19.07 mm, CB = 17.66 mm).
