Hebrus (Hebrus) sp.

(Figs 16, 25)

Material examined. SOCOTRA: Dixam plateau, Tudhen (12°32′42ʺN 53°59′54ʺE), helocrene with Juncus, suction sampler, 1135 m a.s.l., 2♀♀ (ma) 1 L, Socotra expedition 2012: J. Bezděk, J. Hájek,V.Hula, P.Kment, I. Malenovský, J. Niedobová & L. Purchart lgt. (NMPC).

Measurements. Females (n = 2). Body length: 1.85 / 2.05; pronotum: anterior width (across anterolateral angles) 0.41 / 0.43, humeral width (across humeral angles) 0.82 / 0.90; length of antennal segments: I – 0.21 / 0.23, II – 0.16 / 0.18), III – 0.19 / –, IVa – 0.14 / –, IVb – 0.19 / –.

Habitat. It was collected by suction sampler in a helocrene overgrown with grasses and Juncus socotranus at Tudhen (1135 m a.s.l.) in the montane zone.

Note. The examined specimens differ in their blackish colouration with only base of clavus whitish (Fig. 16) and metanotal elevation posteriorly with wide and shallow incision (Fig. 25) from H. (H.) kanyukovae sp. nov. and certainly represent a different species. In sharing the above mentioned characters the two females resemble several species of Hebrus s. str. known from Ethiopia as illustrated by COBBEN (1982a): H. (H.) bimaculatus Cobben, 1982, H. (H.) katompei Poisson, 1950, H. (H.) pseudopusillus Cobben, 1982 or H. (H.) spinitibialis Cobben, 1982 . However, in absence of male specimens the precise identification of the species is impossible.
