Krüger, Andreas, 2019, Notes on Afrotropical Enicocephalidae and Reduviidae (Hemiptera: Heteroptera) with emphasis on vehicle-mounted net samples from Liberia, West Africa, Zootaxa 4688 (2), pp. 232-248 : 233

Embolorrhinus cornifrons (Bergroth & Schouteden, 1905)

( Figs. 1A, B )

Material examined: LIBERIA: Bong county, Bong mine tailings pond area, Dam 16 spillway, 6°47′10″N 10°17′25″W, 145 m, 15.vi.1989, at light, leg. Rolf Garms (2 ♀♀) .

Distribution: Liberia; West and Central Africa.

Henschiella sp.

( Fig. 1C )

Material examined: LIBERIA: Bong county, trips to/from Liberia Research Unit (Bong Mine) —Dam 12—Fahn- Gbolo—Menla—Weadea bridge, 4.iv.–7.vi.1989, vehicle-mounted net, leg. Rolf Garms (20 ♂♂, 4 ♀♀).

Remark: Lacking appropriate reference specimens and facing rather inadequate descriptions a species designation was difficult. However, with reference to Villiers (1969), this is certainly a new record for Liberia, as the only previous West/Central African records, H. seguyi (Villiers, 1955) and H. alluaudi ( Jeannel, 1919) , were from Mauretania and Bioko, respectively. The Liberian specimens differ from the description of H. seguyi by a longer antennal segment III and by rather dark hemelytra, the latter of which also distinguish them from H. sudanica Villiers, 1968 , while the well developed posterior lobe of pronotum disagrees with H. congoensis Štys, 1968 . The Liberian specimens show slight sexual dimorphisms regarding body size, width of basal labium and width of posterior lobe of pronotum.
