Callipallene dubiosa Hedgpeth, 1949

( Figure 7 )

Material examined: ( CEMB, PYC– 018) 1♂, Buleji, 05.xii.2017, on Zoanthus sansibaricus .

Remarks: This species has been recorded from the region previously ( Gul & Ghani 2012). The male is illustrated for the first time. The present specimen resembles Stock’s (1954) illustration more so than Hedgpeth’s (1949) illustrations, because of the large auxiliary claws (approximately half as long as the main claw), the many setae on the sole and the five heel spines. It differs also from the original description on the basis of the number of denticulate spines present on the last four articles of the oviger (7:6:6:6), whilst in Hedgpeth’s description seven or eight spines on the last four articles are mentioned. The distal articles on the oviger are shorter in the original description, and more elongate in the present specimen. These small differences may be sexual.

Distribution: Pakistan ( Gul & Ghani 2012), India, Singapore ( Stock 1954), Tanzania, Kenya ( Müller 1990a), Korea, Japan ( Hedgpeth 1949) Malaysia ( Müller 1992).
