Redescription

LENGTH. Body length (from apex of head to tip of forewings): ♂ 14.1–16.9 mm, ♀ 16.5–17.7 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): ♂ (0.8–1.0)+(1.0–1.2) mm, ♀ (0.8–1.1)+(1.1–1.2) mm; head width (including eyes): ♂ 1.4–1.6 mm, ♀ 1.6–1.7 mm; forewing length: ♂ 11.7–12.6 mm, ♀ 12.3–13.0 mm.

COLORATION. General color ( Figs 1A, C , 2C ) brownish ochraceous marked with pale green and purplish-red on head and thorax, and dark brown and black on abdomen in dorsal view. Head pale green or yellow, head apex (cephalic process) purplish-red to dark brown, frons between intermediate carinae including median carina purplish-red. Clypeus dark purplish red to dark brown. Pronotum and mesonotum greenish or yellowish ochraceous, median carina along with posterior margin, areas behind eyes including lateral carinae and apical margins of paranotal lobes on pronotum, and three broad stripes on mesonotum medially and laterally all purplish-red. Tegulae purplish red. Forewing and hindwing membrane hyaline, except an unsharply delimited brownish macula at apex of forewings; venation brown, stigmal area brown. Thorax greenish or yellowish ochraceous ventrolaterally with an orange or purplish red band adjacent to base of hind coxae. Legs yellowish green, basal sections of femora, apices of fore and middle tibiae and lateral and apical spines all fuscous, apices of all femora dark brown to black. Abdomen dorsally dark brown and black with a paler brownish midline and a longitudinal row of large round yellowish ochraceous spots on each side or abdomen dorsally more or less uniformly yellowish ochraceous and dark brown to black only laterally; ventrally mostly blackish brown, posterior margins of sternites yellowish ochraceous; male and female terminalia dark brown, segment X dorsally yellowish ochraceous.

MALE GENITALIA. Pygofer in lateral view ( Fig. 4E ) large and broad, dorso-posterior margin obtusely angular; in ventral view ( Fig. 4F ) much longer than in dorsal view ( Fig. 4D ) with ratio of ventral to dorsal length about 4.0:1. Gonostyles ( Fig. 4 E–F) symmetrical, sicle-shaped, relatively narrow basally, slightly expanding towards apex, broadest subapically, apex straight; dorsal claw-like process large, elongate, and acute apically. Aedeagus ( Fig. 4 G–I) with endosomal processes ( Fig. 4 G–H) elongate, membranous and acute apically, extended posteriad and strongly curved dorso-anteriad, apex with some minute spines; phallobase sclerotized and pigmented at base, membranous and inflated apically, with one pair of short and thumb-like dorsolateral lobes directed laterad, their apex bearing minute spines ( Fig. 4G ), and one pair of robust, elongate, thumb-like (apically broad) ventral lobes, confluent, curved and directed dorso-posteriad, base with some minute spines ( Fig. 4I ). Segment X, in lateral view, with apical lobes hook-shaped: narrow, sharp and strongly projecting ventrad ( Fig. 4E ); in dorsal view, relatively narrow and elongate, ratio of length to width near middle about 2.2:1 ( Fig. 4D ).

FEMALE GENITALIA ( Fig. 5 A–G) as in generic description.

Distribution

Cameroon, Equatorial Guinea and Gabon; also reported Democratic Republic of the Congo ( Schmidt 1915; Fennah 1958a) and Guinea ( Lallemand 1958) but these require verification. The record from Sierra Leone ( Melichar 1912) is here referred to as C. lindbergae sp. nov.

Remarks

Gerstaecker (1895) described C. jocosa based on material from “Victoria” (= Limbe, 4°01′N, 9°13′E), Cameroon but did not provide any further details on the type series; he particularly did not state the number and sex of the specimens he used for the description nor did he designate a holotype. In the Gerstaecker collection in ZIMG, there is a single male of C. jocosa . It fully conforms the original description including the associated locality data. Following the Recommendation 73F and Article 74 of ICZN (1999), we designate this specimen as the lectotype to stabilize the nomenclature in the genus.
