Identification. BROOKS (1951) (key, redescription, figure); LANSBURY (1966) (figures); WRANIK (2003): 439 (habitus photo); D. A. POLHEMUS & J. T. POLHEMUS (2013) (diagnosis, figures).
Habitat. In Socotra, the species was collected from coastal to montane zone (ca. 100–1170 m a.s.l.). Once it was collected in a large pool with sparse littoral vegetation in a drying wadi (Fig. 49), once in a mountain brook (Fig. 50), and twice at black light (A. Saldaitis, pers. comm.); the remaining records lack habitat information. In Egypt, it was found common in small artificial brackish water pools for goats (LINNAVUORI 1964). In Senegal, the species was collected in small pools in steppe as well as in a garden (JACZEWSKI 1926). In Sudan, it was collected in large and rather deep pools (LINNAVUORI 1971). In Ethiopia and Kenya, it was found only in permanent water at high as well as low altitudes (HYNES 1955). In Zimbabwe, it was collected in pans (small, temporary seasonal lakes) with rich littoral vegetation as well as in small pools (WEIR 1966). LANSBURY (1961a) reported the species in Namibia and South Africa from the following habitats: water-hole with micaceous mud and no vegetation, gravelly and muddy streams from a spring, small shallow ephemeral pool with muddy bottom, and rapid milky stream over rocks and gravel. According to LINNAVUORI (1981) it is found in both oligotrophic and eutrophic pools and rivers.

Nomenclatorial notes. FIEBER (1851) described A. varius to include two distinct forms, ‘ A. sugillata ’ from Sudan and ‘ A. scutellata ’ from Sinai, neither of them considered the nominotypical form. HUTCHINSON (1929), acting as the first reviser, chose A. sugillata as the ‘nominotypical form’, thus making the two names objective synonyms. LANSBURY (1966) accepted HUTCHINSON’ s (1929) opinion and designated a lectotype in the following statement: ‘ Lectotype female (sugillata), one male and three paralectotype females (scutellata) in the Institut für Spezielle Zoologie und Zoologisches Museum, Berlin.’ However, this lectotype designation has no influence on the three type specimens of A. scutellata which remain syntypes. J. T. POLHEMUS (1995) swapped the type localities of A. sugillata and A. scutellata by mistake.
J. T. POLHEMUS (1995: 67) mentioned the holotype of Anisops hoggarica from Tahoun Arak as being lost. However, there is no mention of the holotype in the original description. POISSON (1934a: 135) cited the 3 ♂♂ and 2 ♀♀ as ‘types’, i.e. syntypes.
