Identification. LUNDBLAD (1936) (key, redescription of Rh. i. infernalis , description of Rh. i. africana, figures), BROWN (1956) (description, figures); WRANIK (1999, 2000) (habitus photo of larva); WRANIK (2000, 2003) (habitus photo of adult).

Habitat. Collected on surface of a spring and several small brooks (e.g. Fig. 50 View Figs 49–53.49 ) in coastal to montane zone (5−1170 m a.s.l.). LINNAVUORI (1971) collected Rh. infernalis africana in South Sudan in mountain and rain-forest cold brooks. In contrast, HYNES (1955) found Rh. i. africana in Kenya and Somalia only at altitudes below 200 m where it occurred on both permanent and temporary rivers.

Distribution. Palaearctic Region: Socotra ( BROWN 1956). The nominotypical subspecies R. infernalis infernalis ( Butler, 1876) was described from Rodrigues ( BUTLER 1876, as Velia infernalis ; LUNDBLAD 1936) and subsequently recorded from Reunion ( POISSON 1957b), Mauritius ( MAMET 1957, as Rh. infernalis ; SALLIER DUPIN 1976), and the Comoros ( POISSON 1957d, 1959a, with note on variation). Rhagovelia infernalis andranombyi Poisson, 1952 was described from Madagascar ( POISSON 1952a). Rhagovelia infernalis africana Lundblad, 1936 is widely distributed in continental Subsaharan Africa: Burkina Faso ( SALLIER DUPIN 1979), Central African Republic ( SALLIER DUPIN 1979), Chad ( SALLIER DUPIN 1979), Democratic Republic of the Congo ( POISSON 1942, 1954b, 1963, 1968a; POISSON & SALLIER DUPIN 1969), Ethiopia ( MANCINI 1961), Guinea ( BERTRAND 1962), Ivory Coast ( BERTRAND 1962, POISSON 1968b, SALLIER DUPIN 1979), Kenya ( HYNES 1955, LUNDBLAD 1936, POISSON 1963), Niger ( SALLIER DUPIN 1979), Nigeria ( SALLIER DUPIN 1979), Republic of the Congo ( BERTRAND 1962), Rwanda ( POISSON 1955b), Somalia ( HYNES 1955), South Africa ( POISSON 1957a), South Sudan ( LINNAVUORI 1971), Swaziland ( POISSON 1963), Uganda ( POISSON 1963), Tanzania ( POISSON 1960 a, 1963; SALLIER DUPIN 1976), Togo ( SALLIER DUPIN 1979), and Zimbabwe ( POISSON 1963) as well as in the Palaearctic Region: Israel ( NIESER 1995), Cyprus and possibly also in Greece (Rhodes Isl.) ( FENT et al. 2011).

SALLIER DUPIN (1976) recorded Rh. i. infernalis and Rh. i. africana from the same locality – Kinola, Mts. Uluguru, Tanzania, and listed the distribution of both subspecies as follows: Rh. i. infernalis from Rodrigues, Mauritius, South Africa (Cape, Transvaal), Zaïre [= Democratic Republic of the Congo], Guinea, and Ivory Coast, and Rh. i. africana from Swaziland, Rhodesia [= Zambia and Zimbabwe], Tanzania, Kenya, Uganda ( SALLIER DUPIN 1976). The records of SALLIER DUPIN (1976) require a critical revision.
