Type material.

Holotype: [ Tanzania] D. O. Afrika, Amani [ ZMHB] . Holotype, C. intermedium : Kamerun, C. Conradt leg. [ NHMW] .

Diagnosis.

Length 1.6–1.9 mm. 2.2–2.4 × as long as broad; colour brown. Female frons slightly impressed on central lower half, glabrous and impunctate in middle, with short stiff setae around central area; eye parts narrowly separated by half the size of upper eye part; lateral anterior margin of prothorax with obtuse eye scraper, further below near coxa with short elongated groove; propleural pit present above coxa; elytral suture a little buckled at midlength; apex entire; interstrial vestiture consisting of regular rows of narrowly spatulate setae; posterior part of the metaventrite with unusually long, broad setae.

Distribution.

Cameroon, Tanzania.

New record: Tanzania, Morogoro prov. Udzungwa [GIS: - 7.85, 36.89], ex liana, 29. 6. 2010, B. Jordal leg. [ ZMUB] . Cameroon, Limbe, Ekande [GIS: 4.081, 9.172], 1100 m alt., ex thin liana, 18. 11. 2007, A. Breistøl, leg. GoogleMaps

Biology.

One specimen was collected in each of two localities, in countries with type localities for the two synonymised species C. amanicum and C. intermedium . Both specimens were tunnelling in thin lianas, one under bark and one in pith of a stem nodule in which only a short irregular tunnel was made.

Comments.

The holotype of C. amanicum was supposed to be lost in the museum of Hamburg but was rediscovered in Berlin ( ZMHB). The holotype of C. intermedium is identical to C. amanicum in all important characteristics and therefore synonymised.
