Eupolybothrus segregans sp. n.

Reddish yellow, anteriorly more nearly light chestnut. Legs yellow, the posterior pairs more deeply pigmented.

Antennae composed of 45 articles. Ocelli 1+4,4,3,2, the single oceilus obliquely elliptic, the most caudal ocellus of top series larger than the other seriate ocelli.

Prosternal teeth 7+7, the teeth small and well separated; median interval open V-shaped; anterior margin of prosternum falling back immediately from outermost tooth on each side and then curving outward.

Only the tergites 9,11 and 13 with angles strongly produced. The 7th with angles more weakly produced, those of 6th not at all produced. Fourteenth tergite with caudal margin concave and the corners angular; caudal margin of fifteenth plate also concave with corners rounded.

Penult legs with ventral spines 0,1,3,3,2; dorsal spines 2,0,3,3,2. Anal legs with ventral spines 0,1,3,3,1; dorsal, 2,0,3,1,0; claws 2. Ventral spines of first legs, 0,0,2,3,1; dorsal, 0,0,3,2,1. None of coxae laterally armed.

Coxal pores mostly in two and three series or irregularly in four.

Claw of female gonopods entire; basal spines 2+2, narrowing from base but more strongly acuminate toward tip.

Length, about 22 mm.

Locality: Polonezköy (near Istanbul , Asiatic side), one female taken May 15, 1948 .

A species readily distinguishable from appeninigenus (Brol.) , etc. in having the posterior corners of tergite VI not at all produced. In praecursor Verh. the posterior corners of the sixth tergite are similarly not produced, but in that species the angles of the seventh plate are but weakly produced whereas in the present species they are strongly produced. The posession of two dorsal spines on the posterior coxae may also prove to be a constant distinguishing character.
