Ctonoxylon bosqueiae Schedl, 1962: 66 .

Type material.

Holotype and additional non-types from the type locality of C. bosqueiae : Ghana, Bobiri , Kumasi [ NHMUK].

Diagnosis.

Body length 2.2–2.5 mm, 2.2–2.3 × as long as broad; colour dark brown, dull. Upper and lower eye parts separated by more than 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 distinctly impressed; interstrial setae bristle-like, variable in length and placed irregularly in rows, without ground vestiture; elytral apex entire; resting position of mesotibiae marked on metaventrite.

Distribution.

Ghana.

Comments.

This species is very similar to C. flavescens but differs by the nearly closed gap between the apical tip of each elytron. Genetic data are needed to test the validity of this species. It is only known from the type locality in Ghana. Other published records are removed on the suspicion being the similar and commonly occurring C. flavescens or C. hirsutum . The hostplant Trilepisium is in the plant family Moraceae , similar to many other host records for the flavescens group.
