Eurydice peraticis Jones, 1974

( Figs 4 j, 5c)

Eurydice peraticis Jones 1974: 204 , fig. 3a–g.— Eleftheriou & Jones 1976: 387.— Bruce 1986: 221.— Kazmi et al. 2002: 91, fig. 66a–g.

Material examined. 135 males and females juv. ( SMF 39707) intertidal sand, Bahrain sta. 85085A2, coll. D.A. Jones 1985; 14 males and females juv. ( SMF 39708), intertidal sand, Kuwait, sta. 5157–01, coll. D.A. Jones 2001.

Remarks. These large collections of E. peraticis include male specimens of up to 4.0 mm in length. Examination of the appendix masculina of adult males of 4.0 mm reveal that the appendix masculina has a distinct, pointed apical process, which was absent in the holotype described by Jones (1974). The holotype was 3.3 mm in length and may not have been fully developed, although pereopod 7 was fully setose. The appendix masculina of an adult (4.0 mm) male E. peraticis is shown in Fig. 4 j together with the pleotelson posterior margin ( Fig. 5 c).
