Taxonomy.
Wood & Bright (1992)
state that the
holotype
is in NHML. We have examined the single specimen of this species in NHML. It is not labelled as a type specimen, although the species was described from a single specimen (
Blandford 1895
), and no other specimens of the species have been found in NHML. The specimen in NHML bears the following labels:
Ceylon
/G. Lewis/1910-320 [printed]// Bogawantalawa/
4800-5200 ft
/
28.ii.-12.iii.1882
[printed]//
Dryocoetes
?/
flavicornis Bld.
[in Blandford’s handwriting]. On the underside of the card bearing the specimen is written
3.3.82
. The specimen comes from the type locality, agrees with Blandford’s description, and bears a determination label in Blandford’s handwriting. Even if it is not the
holotype
, it is certainly conspecific.
Blandford (1895)
was in some doubt as to the generic placement of the species, and noted resemblances to species such as
Dryocoetes dinoderoides
, now a synonym of
Dryocoetiops moestus
(see above). Presumably because of this statement,
Wood and Bright (1992)
transferred the species to
Dryocoetiops
although without giving any indication that this was a new combination. The species does not have the characteristics of
Dryocoetiops
. The pronotum is more elongate, is not steeply convex anteriorly and lacks a pronounced summit near the middle. The summit is close to the base. The elytral declivity is much less steep than in species of
Dryocoetiops
. The species belongs in the large genus,
Coccotrypes
, and is transferred here to that genus. The species has not been recorded again since its original description.
