Euscelidia schoutedeni Janssens, 1954 b: 401 ; Oldroyd 1980: 357.

Diagnosis: The species is distinguished, together with nenemusha and schoutedeni , from congeners by the overall brown colour, the predominantly apruinose sct, and the apruinose T 8 in the ^^.

Redescription: Head: Black; fc silver pruinose, fc gib indistinct, mystax white, 6 macrosetae; oc tr apruinose; occ silver pruinose, setae white; Antennae (pped broken) - scp light brown, setae brown; ped brown, setae brown, white pruinose; Thorax: Brown; sct predominantly apruinose, anterior, lateral, and posterior margins silver pruinose, white setae on pruinose area, many long brown presut and psut dc s, macrosetae: brown, 1 npl s, 1 spal s; sctl silver pruinose, ds sctl s and sctl s long, brown; Legs - yellow and light brown, fem yellow proximally, brown distad, tib brown, yellow stripe not reaching tip anteriorly; emp short; Wings - hyaline, brown stained; ptero distinct, brown; cell d terminating in 2 veins; hlt brown; Abdomen: Brown; T predominantly apruinose, lateral and posterior margins white pruinose, T1 with black setae, T2 with white long setae laterally, remaining T with short white setae; ơ terminalia - ơơ specimens unknown.

Type material - The ^ holotype is labelled ‘ HOLOTYPUS (red label with black submarginal border) / MUSEE DU CONGO Haut-Uele. Moto Jun-1922 L. Burgeon (‘Jun’ handwritten) / R. DET. 5409 K. (‘K.’ handwritten; black submarginal border) / Leptogaster n. sp. Det. S. W. Bromley 19 (‘ Leptogaster n. sp. ’ handwritten; label folded) / TYPE (red label with black margin around ‘TYPE’) / R. DET. 6634 I. (‘I.’ handwritten) / E. Janssens det., 1952 Euscelidia schoutedeni E. Janssens (handwritten except for ‘E. Janssens det., 19’)’. The specimen is double mounted (minuten in block of foam), is in good condition (pped and left meso leg broken), and is deposited in the MRAC.

Type locality and distribution ( Fig. 50 ): DR Congo , Haut Uele, Moto, 2 27'N 26 25'E. Cameroon, DR Congo .

Material examined: CAMEROON: 1^ Ebolowa, 2 55'N 11 08'E, 28.ii.1984. Depository: NMSA .

Remarks:The species is only known from two female specimens. It is related to castanea and nenemusha , which are also only known from females. It is necessary to examine male specimens from the type localities of all three species to discuss a probable synonymy.
