description: Omophron (Phrator) schoutedeni Deleve, 1924   
 Description. Holotype body length 11.9 mm; width 7.5 mm. Habitus (Fig. 3).   
Colour: Head and pronotum orange brown. Elytra amber yellow. Legs and antennae yellowish brown. Patches of pronotum and elytral patterns umber, almost black. Mandibles yellowish brown, their apical part umber, almost black. Ventral side yellowish brown; epipleural sides of elytra, pronotum, and prosternum lighter.  
Head fairly flat, rarely and finely punctured. With one supraorbital setiferous puncture on each side of head near the eye. Subocular ridge well developed, curved upwards and slightly rounded. Clypeus wrinkled, bisetose. Labrum distinctly emarginated, with moderately jagged sides and six setae near the front margin. Neck smooth. First segment of antennae unisetose at apex, 5 – 11 segments covered with thin setae, 1 – 4 segments bare, only with some longer setae near apex. Last segment of maxillary palps longer than penultimate segment, with longitudinal impression. HW of holotype: 3.8 mm.  
Pronotum moderately convex, base bisinuated, sides almost straight, gently rounded only towards anterior angles. Sides with well developed edge. Anterior angles nearly acute. Apex and base of pronotum coarsely punctured, disc moderately wrinkled without puncture. Basal impression weakly expressed. Median impression well developed. Pattern on pronotum tripartite, brown, almost reduced. Front part of proepisternum smooth, posterior part coarsely punctured, strongly inclined towards the mesepisternum. Prosternum weakly punctured. PL of holotype: 3.30 mm, PW of holotype: 5.70 mm.  
 Elytra moderately convex, longitudinally oval. Sides slightly concave in two thirds of elytra. Elytra with 15 striae reaching from base to apex. Striae well developed, deep, punctures clearly marked. Near apex, striae become shallower. Intervals expressly convex, smooth, narrower at sides. Elytral pattern consists of rambling dark brown spots, which may be divided in three bands. The median band of elytral pattern converges with apical and basal bands in 6 th and 10 th intervals. Metasternum and metepimeron gently punctured. Sterna smooth, last three sterna with two setae. EL of holotype: 7.65 mm, EW of holotype: 7.50 mm.   
 Comments. Morphologically, this species resembles O.(P.) vittulatum, although O.(P.) schoutedeni is at least 1.5 times bigger. O.(P.) schoutedeni can be distinguished by its orange brown pronotum, darker elytral pattern, and less expressed puncture on the base of pronotum.   
 Significant differences in the build of aedeagus compared to other species of subgenus Omophron (Phrator) were not observed in this species.   
 Distribution. Known only from one type location (Djokopunda, Kasai Province, Democratic Republic of Congo). Distribution map (Fig. 7).
