Liang, 2016 [newly added red label]” (MMBC; dry-mounted, pinned through mesonotum, abdomen detached and stored in glycerine in a glass microvial pinned under the specimen). Redescription LENGTH. Body length (from apex of head to tip of forewings): ♂ 13.3 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: ♂ 10.4 mm. COLORATION (Fig. 2B, E). Largely similar to C. jocosa, but much paler than the latter, without dark brown or black on abdomen in dorsal habitus. Head including cephalic process pale green, a longitudinal stripe in front of eyes on genae and median carina on frons reddish ochraceous (Fig. 8A, C). Pronotum and mesonotum greenish ochraceous, median carina along with posterior margin, areas behind eyes including lower lateral carinae and apical margins of paranotal lobes on pronotum, and median carina and lateral areas on mesonotum reddish ochraceous. Forewings and hindwings with venation and stigmal area pale greenish ochraceous. Abdomen dorsally and ventrally greenish ochraceous. Apical lobes of male segment X black (Fig. 8E). MALE GENITALIA. Pygofer in lateral view (Fig. 8E) slightly shorter than in C. jocosa and C. lindbergae sp. nov., ventral margin longer than dorsal one with ratio of ventral to dorsal width about 3.0:1; dorsoposterior margin right-angled. Gonostyles (Fig. 8 E–G) broad, strongly expanding towards apex, broadest and convex subapically; dorsal claw-like process narrow and elongate, apex acute. Aedeagus (Fig. 8 H– J) lacking distinct endosomal processes; phallobase sclerotized and pigmented at base, membranous and inflated apically, with one pair of large, robust, triangular dorsolateral lobes, directed laterad, without superficial spines (Fig. 8H); and one pair of short and thumb-like ventral lobes, directed straightly posteriad (Fig. 8I). Segment X, in dorsal view, elongate with ratio of length to width near middle about 1.7:1 (Fig. 8D); in lateral view, ventral margins straight, apical lobes blunt, rounded, weakly produced ventrad (Fig. 8E). Female unknown. Distribution Equatorial Guinea. Remarks This species was described by Melichar (1912) based on two male specimens from Fernando Poo [= Bioko], Equatorial Guinea, originally coming from the collection of the museum in Genoa, Italy. One of these two syntypes has been preserved in Melichar’s personal collection in MMBC. According to Article 74 of ICZN (1999) we designate this specimen as a lectotype for C. simplex to stabilize the nomenclature. We have redescribed and illustrated the species based on the lectotype.
