( Figs 4 , 11–14)

Type material. Holotype: Democratic Republic of the Congo (Oriental Prov.): ♂, two labels: " DR CONGO, Oriental Prov. / Ituri region, Mongbwalu, AGK camp, / house backyard / N01º56'32.81'', E30º02' 25.62 / 21- 28.ii.2015 / yellow pan, leg. A. GUMOVSKY" [white, printed], " POMPHOPSILLA / pseudosoror m. / P. Jałoszyński, '16 / HOLOTYPUS' [red, printed] ( SIZK). Paratypes: 2 ♂♂, two labels: " DR CONGO, Oriental Prov. / Ituri region, Mongbwalu, AGJ camp, / abandoned shamba, bananas, avocado, / sweet potato / N01º56'32.81'', E30º02'25.62'' / 20-27.iii.2015 / yellow pan, leg. A. GUMOVSKY" [white, printed]; " POMPHOPSILLA / pseudosoror m. / P. Jałoszyński, '16 / HOLOTYPUS' [yellow, printed] ( SIZK, cPJ).

Diagnosis. Aedeagus slender, with circular diaphragm; dorsal apical projection in ventral view concealed under conspicuous median apical plate, which is elongate, darkly pigmented and inversely subtriangular; apex of ventral aedeagal wall rounded; endophallus lacking needle-like sclerites, median tubular structure in median region with bell-shaped and unevenly sclerotized central complex.

Description. This species ( Fig. 4 ) is externally nearly identical to P. pygmaea , only differences and measurements are given here.

BL 0.75–0.80 mm. HL 0.09–0.10 mm, HW 0.18–0.19 mm, AnL 0.35–0.38 mm, antennomere III subquadrate, IV–IX each elongate. PL 0.23–0.24 mm, PW 0.29–0.30 mm, inner pair of pronotal pits connected by indistinct transverse groove; EL 0.43–0.48 mm, EW 0.35–0.38 mm, EI 1.13–1.29.

Aedeagus (Figs 11–14) relatively slender, pear-shaped, AeL 0.20 mm; median lobe in ventral view with circular diaphragm in sub-basal region; apex of ventral wall rounded, apex of dorsal wall in ventral view hidden behind large, inversely subtriangular median plate; endophallus with median tubular structure in median region flanked by irregularly sclerotized components together forming a bell-shaped central complex; parameres slender, their apices not reaching apex of dorsal aedeagal wall, each with one long and one short apical seta.

Female. Unknown.

Distribution. North-eastern part of DR Congo.

Etymology. The specific epithet pseudosoror refers to the similarity between this species and previously known P. s o ror.

Remarks. Pomphopsilla pseudosoror has the aedeagus very similar to that of P. s o ror, known to occur in Kenya. However, the apical portion of the dorsal aedeagal wall in P. s oro r is much longer in relation to the median plate, and apices of parameres slightly exceed the distal margin of the median plate (in P. p s e u do ro ro r apices of parameres only slightly exceed the base of median plate).
