Genus Albrehmus Gnezdilov , gen. nov.

Type species: Issopulex chloe Linnavuori, 1973 , by present designation.

Diagnosis. Male and female brachypterous, with head and body with fore wings covered with sparse tiny depressions with setae inside. Fore wings short, reaching or slightly surpassing beyond hind margin of third abdominal tergite, venation indistinct. Metope visible from above, wide, with weak sublateral carinae running from its upper margin to metopoclypeal suture. Postclypeus large, with median carina. Coryphe transverse, 2.5 times as wide as long medially, nearly hexagonal. Coryphe and metope joint at obtuse angle in lateral view. Pedicel with a process. Eyes large. Pronotum short, nearly as long as coryphe, transverse. Paradiscal fields of pronotum very narrow behind the eyes. Paranotal lobes of pronotum large. Mesonotum large, nearly 2.5 times as long as pronotum medially. Femora and tibiae not flattened neither foliated. First and second metatarsomeres each with only two latero-apical spines.

Male genitalia structure (after Gnezdilov & Bourgoin 2009, figs 70–74). Male pygofer elongate vertically, with nearly straight hind margins. Anal tube wide, narrowing apically in dorsal view. Anal column short and wide. Phallobase symmetrical, concave in ventral and lateral views, with pair of large apical lobes above ventral aedeagal hooks. Aedeagus with pair of long curved and acuminate ventral hooks directed downwards. Style with elongate vertically plate, straight hind margin, and widely rounded caudo-dorsal angle. Capitulum of style long and narrow.

Hind margin of female sternite VII generally convex, with slight median concavity.

Etymology. The genus is named in honour of well-known German naturalist Alfred Edmund Brehm (1829– 1884) who travelled to Kordofan in the middle of XIX century.

Composition and distribution. Monotypical genus known from the Republic of Sudan (South Kordofan) and northern Nigeria ( Linnavuori 1973; Gnezdilov & Bourgoin 2009).
