A careful search during a personal visit at the MNHN in November 2021 revealed there is no specimen from Senegal. BURGEON (1935) reports on page 150 “Le type unique est perdu.” It is also not deposited in the collection of Puzeys curated in RBINS and personally checked in November 2021. However, designation of a lectotype should be performed when all the sub-collections in the large treasure of the MHNN have been checked. The type of C. pumilia should be deposited in the museum of Saint Petersburg. It is not available for study at this time. In total, 355 specimens were investigated including specimens from Senegal. Around 10% of these specimens were already determined by Basilewsky and Kult. The specimens correspond exactly to the descriptions of PUTZEYS (1846), BURGEON (1935), and KULT (1959). Although the type of C. pumilia is not available, I completely share the interpretation of KULT (1959, p. 215) regarding the synonymy. In addition, the material reported by LUTSHNIK (1926) was collected in Sierra Leone which is located in the tropical rain forest belt of Africa surrounded by other finds. The specimen from Eala reported and roughly characterised as “ C. dumoloni ” by BURGEON (1937, p. 393) is obviously C. burgeoni Kult, 1959. EXTENDED DIAGNOSIS. A small sized fuscous species with the following measurements: Body length 3.77–4.14 mm (x = 3.92 mm *), width 1.07–1.18 mm (x = 1.12 mm *), ratio L/W of pronotum 0.94–0.98 (x = 0.95*), ratio L/W of elytra 1.86–1.97 (x = 1.89*); (*n = 10). The apex of the elytron is more or less pale fulvous coloured. Wing of the clypeus small. Eye distinctly convex in dorsal view. Pronotum with lateral margin indistinctly convex and slightly attenuating anteriorly, on the disk baso-laterally with small but distinct group of punctures, medially with group of punctures, proepisternum tumid laterally but just not visible in dorsal view. Elytra with the shape long-oval with straight and diverging part of the lateral margins, with maximum width slightly behind middle, intervals smooth and glossy in both sexes, row of umbilical setigerous punctures of the lateral channel interrupted posterior humerus and at middle. Abdominal sternite in males and females smooth and glossy at middle, laterally with some punctures. Mesotibia with row of eight setigerous tubercles latero-dorsally, with row of setigerous tubercles laterally. Hind wing: Fully developed. Male genitalia (Fig. 6): Median lobe slender, distinctly and at middle regularly arcuate, with wide and rounded spatula. Endophallus with larger group of bristles basally. Female gonocoxite and epipleurite (Fig. 10): Gonocoxite foliform with clubbed shape, completely flattened, with three robust nematiform setae positioned at the median side, subapically with one small seta. Epipleurite long quadrangular, asetose. Sexual dimorphism at the integument: Not observed. VARIATION. The clypeal wings are more or less convex. On the disk of the pronotum, the median group of punctures is developed with variable number and distinctness and more or less extended anteriorly. The smaller punctures scattered on the disk are more or less dense. On the abdominal sternite, the laterally situated punctures vary in number. The pale coloration at the apex of the elytron varies from just traceable at the tip of the apex to one fifth of the posterior elytron. Most distinguishing characters from the similar species E. basilewskyi sp. nov. are the smooth and glossy surface of the abdominal sternite (in both sexes), the more convex eye, the different shape of the male aedeagus and of the female gonocoxites. DISTRIBUTION. The species is widely distributed along the tropical rain forest belt of Africa from Senegal to Zimbabwe. The summarized data confirm the faunistic records from different regions along the rain forest belt (BASILEWSKY, 1948, 1952, 1953, 1955, 1963, 1967, 1968, 1969).
