( Fig. 7A )

Tapinomorphus sylvicola Voss, 1962: 291 (original description).

Cathormiocerus africanus Hoffmann, 1965: 394 (original description), syn. n.

Type locality. Kilimandjaro [ Tanzania].

Material examined. Tapinomorphus sylvicola . Paratype: 1 spec. (RMCA), PARATYPUS [orange label, p] / Récolté dans l´humus [blue label, p] / COLL: MUS. CONGO Tanganyika Terr.: Kilimanjaro, Marangu, 2400m, 20- II-1956 [p] / Mission Zoolog. I.R.S.A.C. en Afrique orientale (J. et N. Leleup) [p]. Cathormiocerus africanus . Lectotype (here designated): 1 spec. (NHMW, Franz’s coll.), ‘Kilimanjaro, Tanganyika [p] / Gebrigswald ob. Marangu lg. H. Franz [p] / TYPE [p, red] / Cathormiocerus africanus m. ♂ [hw], A. Hoffmann det. [p] / LECTOTYPE, Cathormiocerus africanus Hoffmann, R. Borovec & J. Skuhrovec des. 2017 [red label, p] / Tapinomorphus sylvicola Voss , syn. n. R. Borovec & J. Skuhrovec det. 2017’ [p] ( Fig. 7A ). Paralectotypes: 4 spec. (NHMW, Franz’s coll.), same data as lectotype but without Hoffmann’s identification label and with a label reading ‘PARALECTOTYPE, Cathormiocerus africanus Hoffmann, R. Borovec & J. Skuhrovec des. 2017’.

Remarks. Hoffmann (1965) based his description of Cathormiocerus africanus on seven specimens, in the collection of H. Franz (NHMW). One of them is fitted with a red “ TYPE ” label and an identification label by Hoffmann reading “ Cathormiocerus africanus m. ♂ ”, but the others are only labelled as “ Cathormiocerus sp. n. ” by Hoffmann. Four of them carry the same locality labels as the “ TYPE ”, and we treat them to be other syntypes of the same species. The other two specimens are labelled as follows: ‘ Kilimanjaro, Tanganyika [p] / Kibo SW-Hang, 2500–3100m lg. H.Franz [p]’, and they apparently belong to another species of the same genus, which we describe below.

All these type specimens attributed by Hoffmann to Cathormiocerus clearly differ from this Palaearctic genus and are assignable to the genus Tapinomorphus Hartmann, 1904 (tribe Sciaphilini ) on the following characters: epifrons at base almost as wide as space between eyes, clearly separated from head by narrow, V-shaped sulcus; frons glabrous and declivous; antennal scrobes laterally placed, well defined but wide, reaching eyes; elytra angular; procoxae touching anterior border of pronotum; metatibiae lacking corbels, with glabrous apical surface; claws connate; metaventral process very wide; abdominal ventrite 2 as wide as ventrite 3 or 4, with suture between ventrite 1 and 2 straight. The type specimens of Cathormiocerus africanus are conspecific with the type material of Tapinomorphus sylvicola Voss, 1962 , and we therefore here synonymise these two names.
