( 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.
