Ommatoiulus oliveirae (Verhoeff, 1893) Fig. 17 Julus oliveirae Verhoeff, 1893b: 161 –163, figs 27–28. Palaioiulus oliveirae – Verhoeff 1894: 156, fig. III Ommatoiulus oliveirae – Vicente 1985: 324. — Bailey & De Mendonça 1990: 104. Material examined PORTUGAL: Syntype, gonopods, slide preparation (ZMB13086) herewith designated as lectotype of Julus oliveirae; 3 ♂♂, 3 ♀♀, 1 slide preparation, undetermined locality, Paulino d’Oliveira leg. (NHMW 8044); 2 ♂♂, 1 ♀, Setúbal District, Grândola, under stones, in grassland, 3 Nov. 1986, P. Bailey leg. (ZMUC). Diagnosis Most similar to O. armatus and O. dorsovittatus in the voluminous solenomerite with lobes and a serrated furrow, the presence of a lateral notch on the promerite and the reduced paracoxite. Different in the distal part of the mesomerite, promerite and a more slender shape of the solenomerite and paracoxite. Descriptive notes Promerite simple, in posterior view gradually narrowing in its distal half, apex rounded and lateral margin shallowly incised (Fig. 17 A, C); mesomerite (Ms) large, extending beyond the rest of the processes, curved laterad and distally expanding into two oppositely directed processes (Fig. 17 B, D); solenomerite (S) with a main process reaching ¾rd of mesomerite length, marginally strongly serrated, apically with a rounded lobe covered with short spines and a small pointed accessory process (Fig. 17 D), paracoxite (Px) slender, almost as long as solenomerite (Fig. 17 B, D) and emerging from a broad coxa (Cx). Distribution PORTUGAL: Coimbra (Verhoeff 1893b); Setubal Province, Grândola where it is sympatric with O. moreleti and O. lusitanus (Bailey & De Mendonça 1990). Additional records (Kime, pers. comm.): Faro Province, West of Monchique, in cork litter, 29 Sep. 1987, P.T Bailey. Habitat Abundant in Quercus litter but also found in Cistus litter, also occurring in grasslands (Bailey & De Mendonça 1990), syntopic with O. moreleti and O. lusitanus.
