Identification. POISSON (1929) (description, figures); POISSON (1934a) (original description repeated, figures); POISSON (1936): 214–215 (diagnosis, figures); LINNAVUORI & HOSSEINI (2000) (key, diagnosis, figures); LINNAVUORI et al. (2011) (diagnosis, habitus photo).

Habitat. In Socotra, the species was collected in the medium elevation zone in a large pool with sparse littoral vegetation in a drying wadi ( Fig. 53 ). Outside Socotra, it was collected in ponds, shallow pools with sandy bottom, rivers, rocky streams without vegetation, brook with gravelly bottom, rocky pools in a dried-out wadi, shallow irrigation dikes as well as in rice-field ( BROWN 1951; HYNES 1955; LINNAVUORI 1964, 1971, 1981, 1986a, 1994b, 2009; LINNAVUORI & VAN HARTEN 1997 ; ALAHMED et al. 2009; LINNAVUORI et al. 2011). Also collected at light ( LINNAVUORI 2009, LINNAVUORI et al. 2011). ALAHMED et al. (2009) reported S. hoggarica as an efficient predator of mosquito larvae.

Distribution. Afrotropical Region: Chad ( DISPONS 1965), Ethiopia ( HYNES 1955), Mauritania ( VILLIERS 1951), Niger ( POISSON 1950a, LINNAVUORI 1981), Sudan ( LINNAVUORI 1971). Palaearctic Region: NorthAfrica:Algeria ( POISSON 1929, 1948b), Canary Islands ( BAENA & BÁEZ 1990, ROCACUSACHS et al. 2020), Egypt ( PRIESNER & WAGNER 1961, as S. brevixipha ; LINNAVUORI 1964), Libya ( POISSON 1948b); Near East: Iraq ( LINNAVUORI 1994b), Iran ( LINNAVUORI 2004, 2009; GHAHARI et al. 2013), Israel ( BAENA & BÁEZ 1990, JANSSON 1995, both without exact record), Oman ( AUKEMA et al. 2013, without exact record), Saudi Arabia ( BROWN 1951, 1953b, both as S. brevixipha ; LINNAVUORI 1986a; ALAHMED et al. 2009), Socotra (this paper), United Arab Emirates ( LINNAVUORI et al. 2011), Yemen ( BROWN 1951, as S. brevixipha ; LINNAVUORI 1989b; LINNAVUORI & VAN HARTEN 1997 ). Oriental Region: Pakistan: Balochistan ( HUTCHINSON 1940, as S. choprai ), India: Himachal Pradesh ( HUTCHINSON 1940, as S. choprai ). New to the Socotra Archipelago.

Notes. The record from Asian Turkey by NIESER & MOUBAYED (1985) is erroneous (cf. FENT et al. 2011).

POISSON (1936: 214) incorrectly treated S. (T.) lundbladiana Hutchinson, 1932 as a synonym of S. hoggarica (see JANSSON 1995: 54).
