| | | | | | | Ref.: | | | Fleminger, 1988 (p.309, figs.F,M); Huys & Boxshall, 1991 (p.49) |  issued from : A. Fleminger in Proc. Biol. Soc. Wash., 1988, 101 (2).[p.311, Figs. 1-8]. Female (from San Diego, California): 1, habitus (lateral left side); 2, forehead (ventral); 3, Pediger 4-5, urosome, P5 and distal ends of A1 (right lateral); 4, Pediger 4-5, urosome and ends of A1 (dorsal); 5, genital segment and P5 (ventral); 6, Pediger 4-5, urosome and P5 (ventral); 7, Md (masticatory edges; posterior); 8, right Mxp (lateral). Nota: Rostrum indicated by pair of small knobs. seen in ventral view. Genital segment longest, being slightly shorter than combined lengths of urosome segments 2 and 3; symmetrical in dorsal view. A1 24-segmented, reaching posteriad to midlength of genital segment. P5 symmetrical resembling those in P. occatum but proportionally shorter, when extended posteriad reaching barely past midlength of genital segment; in P. pallidusP5 asymmetrical, longer left reaching beyond midlength of urosome segment 2

 issued from : A. Fleminger in Proc. Biol. Soc. Wash., 1988, 101 (2).[p.312, Figs. 9-19]. Female: 9, P1 (posterior); 10, P2 (posterior); 11, P3 (posterior); 12, P4 (posterior); 13, P5. Male: 14, habitus (lateral left side); 15, idem (lateral right side); 16, prosome (dorsal); 17, Pediger 4-5, urosome and P5 (lateral right side); 18, P5 (posterior); 19, P5 (anterior). Nota: Urosome 5-segmented. A1 reaching posteriad to Pediger 4-5 (in P. occatum A1 reaches to caudal ram). P5 similar to that of P. occatum.

Distribution map of Parastephos esterlyi by geographical zones
|
| | | | Loc: | | | California (San Diego) | | | | N: | 1 | | | | Lg.: | | | (549) F: 1,33-1,14; M: 1,26-1,21; {F: 1,14-1,33; M: 1,21-1,26} | | | | Rem.: | coastal (Bights).
For Fleminger (1988, p.309) the species is similar to P. occatum differing in details of the genital segment, in the length of A1 relative to the urosome and in P5 relative to the length of the urosome.
For Kos (2016, p.9, 10) the genus Parastephos is a junior synonym from Stephos. | | | Last update : 08/02/2019 | |
