( Figs 5 , 17 )

Odontolochus ferenczi Endrödi, 1976: 163 –164 — Dellacasa 1988: 286 (catalog).

Material examined. Holotype male [ Guinea] 'Grandes Chutes, 15.IX–15.X.1966, leg. K. Ferencz’/, ‘ Holotypus Odontolochus ferenczi Endrödi’ ( HNHM); paratypes (4): Guinea, Coyah, II–III.1967, VIII– IX.1967, 22.XI.1967, 31.I.1968, leg. K. Ferencz ( HNHM).

Other specimens (11). Guinea: Coyah, 15.XI.1967 – 20.III.1968, 23.V–25.VII.1967, 15.III–15.VI.1969, leg. K. Ferencz ( HNHM); Coyah, IV.1967, leg. K. Ferencz ( ISEA); Coyah, Reg. Kindia, Mt Gangan 800 m, 1951, leg. Bechyne ( MHNG). Sierra Leone: Makeni, 23.03W, 8.53N, 27.XI.1993, light trap, Lund Univ. Sierra Leone Exp. 1993 ( MZLU). The Gambia: Kabafita Forest Park, 2.2 km NNW Brikama, 5.XI.1977, at light in close forest savanna, Lund Univ. Gambia-Senegal Exp. 1977 ( MZLU).

Diagnosis. Pronotum subquadrate, median anterior area moderately elevated, side sinuate, converging to basal angulation. Elytra convex, striae deep with moderate punctures; intervals 1–5 convex, wider than striae, intervals 6–10 obtusely carinate, nearly as wide as adjacent striae; in some specimens intervals 2, 4, 6 less convex than the remained intervals or even flat. Odontolochus . ferenczi is similar externally to O. gestroi , but differs in having the pronotal punctures finer and less close and lateral pronotal angulations less prominent than in O. gestroi .

Description. Length 2.5–3.0 mm. Body ( Fig. 5 ) dark brown to piceous, dull. Head finely punctate throughout, clypeal margin slightly reflexed. Pronotum quadrate, median anterior area moderately elevated, anterior angles right-angled, protruding laterad, side sinuate, converging to basal angulation, base straight with row of punctures; surface with lateral oblique fossulae filled with close punctures, moderate punctures evenly distributed, in anterior one-third of pronotum fine, close, becoming larger and less close toward base. Elytra convex, humeral denticles very minute; striae deep with moderate punctures; intervals vary in height, usually similarly developed, in some specimens intervals 2, 4, 6 less convex than the remained intervals or even flat; intervals 1–5 convex, wider than striae, intervals 6–10 obtusely carinate, nearly as wide as adjacent striae. Ventral surface alutaceous; mesosternum with median area convex, lateral grooves parallel-sided, extending to metasternum, each groove with 2–3 coarse punctures; metasternum convex, finely punctatesetose from side to side; abdominal sternites with row of distinct fluting along punctate sutures, disc of pygidium eroded. Mesofemora and metafemora parallel-sided, with scattered minute punctures; protibia in both sexes similarly shaped ( Fig. 17 ); basal metatarsomere nearly as long as upper tibial spur and equal in length to following three tarsomeres together.

Male. Disc of pygidium longer than in female.

Distribution. The species is known from The Gambia, Guinea, and Sierra Leone.
