Synonym by Eggers 1920.     Ctonoxylon conradtiSchedl, 1939: 171, syn. nov.   Type material.    Holotype: Kamerun[  ZMHB].    Holotype  C. conradti, female: [ Tanzania] Insel Ukerewi[  NHMW].   Diagnosis. Length 3.4–3.8 mm. 2.0–2.1 × as long as broad; colour brown. Upper and lower eye parts separated by 1.5 × the width of upper part; pronotal eye scraper acutely pointed; a sharp carina running from scraper to procoxa, without associated groove or propleural pit; scutellar shield at level with elytra; striae weakly impressed; interstrial setae sort, bristle-like, dense, confused with similar typeof ground vestiture; elytral apex slightly emarginated; elytral suture buckled on disk; resting position of mesotibiae marked on metaventrite.   Distribution.  Liberia(new country record), Ivory Coast, Nigeria, Cameroon, Equatorial Guinea, Gabon, Democratic Republic of the Congo, Angola, Tanzania.   New records.   Liberia, Suakoko[ 6.98, - 9.54], 28.1–  5.5. 1952, light trap, Blickenstaffleg (47); Cape Mount[ 6.72, - 11.34], 1940, M.

Gruwell[  USNM].   Comments. The holotypeof  C. conradtiwas compared to a specimen of  C. camerunumdetermined by Hagedorn in ZMHB, which is possibly the holotype. The type of  C. conradtihas slightly shorter elytral setae and is less shiny than  camerunum, but this is very likely within species variation. 4869223307 ZMHB Cameroon Kamerun 1 holotype 4869223318 NHMW Tanzania Insel Ukerewi 1 holotype 4869223332 1952-05-05 light trap USNM Blickenstaff & M.
