Diagnosis

The species is formally described here in the absence of males but it can be distinguished from all other Centromeriana species by asexual characters, particularly the backward inclination of the cephalic process which also has a relatively smaller size. From C. jocosa and C. lindbergae sp. nov. it also differs in the clear forewing apex and from C. simplex in the body coloration, having a dark pattern, particularly on the abdomen.

Etymology

The specific epithet is a noun in apposition derived through Latin from the Ancient Greek word ρίνóκερως (= rhinoceros), which is composed of ρίνο- (= nose) and κέρας (= horn). The new species is named for its horn-shaped cephalic process.

Paratype

TOGO: 1 ♀, “Toǵo, Bismarckburǵ, L. Conradt [dark blue printed label]; PARATYPE [newly added yellow printed label]; ♀, Centromeriana rhinoceros sp. nov., det. Z.S. Song, I. Malenovský & A.P. Liang, 2016 [newly added red printed label]” ( MFNB, dry-mounted: pinned through mesonotum).

Description

LENGTH. Body length (from apex of head to tip of forewings): ♀ 14.4 mm; head length (including two portions: the former is from apex of cephalic process to constricted and curved part, and the latter is

from curved part to base of eyes): ♀ 0.7+1.0; head width (including eyes): ♀ 1.4 mm; forewing length: ♀ 11.9 mm.

COLORATION ( Figs 2A, D , 7 A–C) AND STRUCTURE. Largely identical to C. jocosa except for the forewing membrane which has clear apex ( Fig. 3C ). Cephalic process in lateral view relatively short, strongly upturned and curved upward and slightly backward in more than 90° ( Fig. 7B ).

Male unknown.

Distribution

Togo.
