Exopod of uropod as long as telson, with two spines on posterior half of outer margin; telson with 45 pairs of dorsolateral spines and one pair of distal spines (Fig.
Uropod with broad mmi; exopod with two small spines at posterolateral angle and with distinct transverse suture; posterolateral projection of protopod terminally blunt.
Also, the reduction of the exopod on the first maxilliped and the loss of the grooming apparatus on the carpus of the first pereopod are also remark able.
The initial number of setae 3, 5, 5 in the exopods of the third maxilliped and pereopods and their gradual increase are also similar to the reported species.
58 4 Pairs of setae in the exopods 3rd 1st 2nd Stage Instar maxill.
Exopods of pereiopods 3 and 4 were usually devoid of setation and nub-like (Table 1), as in the postlarva; in some specimens, however, these exopods were longer than that of a normal postlarva.
These three larvae (designated VD/PL/J) possessed setose exopods on pereiopods 1 and 2 (as in form D) and had a telson morphology (i.
ensis within peneids seems to agree with some atypical morphologic characters like the petasma with distolateral projections, the lack of pleurobranchia and exopod on fifth pereiopod, the fifth male pereiopod modified and the presence of basial spine on third maxilliped and pereiopods 2-3.
Mxp2 and Mxp3 are held laterally, with their endopods bent into a U-shape and the flagella on their exopods (Mxp2 exo and Mxp3 exo) beating almost continuously in a dorso-ventral plane.
When moving ventrally, the anterior part of the Scapho sweeps across the epipod of Mxp1 and the exopods of Mxp2 and Mxp3, and these structures help direct the exhalant current (Fig.
In females the endopods were longer and wider than the exopods, and the EWIs of immature (1.
