Material examined. Egypt: 1♀, “Gebel Elba, Egypt / Dr. H. Priesner // R. E. Linnavuori coll. / NMW.Z. 1996. 163” ( NMW). Erithrea : 1♀, “Erithrea / Decamere / 25- 26.5.1963 / Linnavuori // R. E. Linnavuori coll. / NMW.Z. 1996. 163” ( NMW) .

Description. Female. Structure. Body strongly convex in lateral view ( Fig. 31). Face (metope with postclypeus) chisel-shaped in frontal view ( Fig. 32). Metope wide, with very smooth sublateral carinae running from its upper margin to metopoclypeal suture and with distinct median carina running from its middle throughout postclypeus. Postclypeus strongly flattened laterally, glossy. Pedicel barrel-shaped, with a process and sensory organs. Ocelli absent. Coryphe transverse, nearly hexagonal, without carinae; posterior margin slightly concave ( Fig. 30). Coryphe and metope joint at obtuse angle in lateral view. Pronotum nearly as long as coryphe medially, with smooth median carina. Paradiscal fields of pronotum very narrow behind the eyes. Paranotal lobes of pronotum elongate. Mesonotum 2.5 times as long as pronotum, without carinae. Fore wings short, almost reaching hind margin of third abdominal tergite; venation indistinct except weak radius. Legs not flattened neither foliate. Hind tibia with a single lateral spine near to its middle and with five apical spines. First metatarsomere slightly longer than second one, with dense short and thick setae ventrally. Second metatarsomere with dense hair-shaped setae ventrally. First and second metatarsomeres each with only two latero-apical spines.

Female. Coloration ( Figs 30–32). Scapi, pedicels, coxae, and hind legs dark brown. Coryphe pale, with dense light brown dots. Metope mostly pale, with dense light brown dots except dark brown to black laterally above clypeus. Postclypeus dark brown to black, with pale median carina. Episternae and epimerae dark brown to black. Pro- and mesonotum pale, with dense light brown dots except dark brown to black laterally. Fore wings brown except pale claval margins. Fore legs and middle and hind tarsi yellowish light brown. Claws dark brown. Apices of leg spines black. Abdominal tergites dark brown to black, with light yellow stripes and spots—wide median stripe on tergites III– V and narrow stripes or spots on others. Abdominal sternites and ovipositor dark brown to black.

Female terminalia ( Figs 28, 29). Hind margin of sternite VII generally convex, with slight median concavity ( Fig. 28). Gonoplacs short, slightly surpassing beyond apex of anal tube in lateral view ( Fig. 31). Anal tube wide, narrowing apically in dorsal view ( Fig. 29). Anal column short, globular.

Total length. 3.2 mm.

Note. Photos of male habitus and the drawings of male genitalia structure were erroneously published under the name Savanopulex endroedyi Dlabola ( Gnezdilov & Bourgoin 2009, figs 23–25, 70–74). No significant differences in male genitalia structure of the specimens from Sudan and Nigeria were found. Linnavuori (1973) mentioned that the species was collected on light which is rare for brachypterous insects, however, within the Caliscelidae it is also known for Adenissus fuscus Gnezdilov, 2017 , collected on light in the United Arab Emirates ( Gnezdilov 2017b). The females recorded above from Egypt and Erithrea are assigned to Albrehmus chloe according to habitus, particularly the shape and the carination of the head.
