Ibizella asilahica nov. sp.

M a t e r i a l e x a m i n e d: 1♂, 1 protonymph. Locus typicus: Asilah, 9 September 1999, Morocco, from undetermined Tenebrionidae . Both specimens are deposited as holo- and paratype respectively [ Aescht ] at the Museum of Natural History , Wrocław University , Poland.

D i a g n o s i s: Propodosomal plate narrow and short, setae ve absent, sejugal suture absent, c 2 <70, tarsi I-IV (without pretarsi)> 30, SS 24, setae cG I-II and mG I-II very short <30.

D e s c r i p t i o n (♂): Male (based on holotype) – Idiosoma without ornamentation with narrow propodosomal plate and setae vi. Propodosoma with very long setae se and short setae si and sl. Sejugal suture absent. Hysterosoma with 6 pairs of setae; setae c 2, d 2 and e 2 distinctly longer than setae c 1, d 1 and e 1 ( Fig. 1 ).. Ventral side of idiosoma with very long setae h 1, h 2, cp, distinctly shorter setae h, c 3 and f 2 and short setae 1a, 3a, 4a, 4b, g, p 1, p 2 and p 3. Bases of setae h 1, h 2 and h 3 placed near posterior margin of idiosoma. Penis short. The adanal suckers well developed ( Fig. 2 ). Gnathosoma not covered by idiosoma. Leg I-IV short. Setea cG and mG on Ge I and Ge II short, setae cG I and II only little longer than setae mG I and mG II ( Figs 3-6 ). Measurements are given in Table 1 .

Females unknown.

Protonymph: Dorsal side of idiosoma with long setae se and three pairs of short setae vi, sl and si on propodosoma. Propodosomal plate invisible. Sejugal suture absent. Idiosoma without ornamentation. Hysterosoma with 6 pairs of setae; setae c 1, d 1 are short, setae c 2, d 2, e 1 and e 2 are distinctly longer ( Fig. 7 ). Ventral side of idiosoma with long setae cp, h 1 and h 2, shorter setae f 2 and h 3 and distinctly shorter setae 1a, 3a, 4a, g, p 1, p 2 and p 3 ( Fig. 8 ).Tarsi I-IV and legs I-IV short ( Figs 9-12 ).

E t y m o l o g y: The species is named after the type locality [Aescht].
