Pseudophacopteron carapae sp. nov.

( Figs. 35 , 101–102, 186, 234, 252)

Description. Examined only from slide-mounted specimens. Adult. Colour. Fore wing membrane transparent, clear, except for a dark brown infuscation along full length of vein Cu 1b ( Fig. 35 ). Fore wing veins off-white, except for C+Sc, basal two thirds of R, basal half of M, the M+Cu 1 fork, a spot medially on R+M+Cu 1, and two spots on anal vein, which are all dark brown to black. Hind wing clear, transparent, C+Sc dark brown.

Morphology. Head similar to P. zimmermanni . Antenna relatively slender, segments slightly widening to apex; terminal setae subequal, short, the longer terminal seta about as long as segments 9 and 10 together ( Fig. 234 ). Fore wing pyriform, rounded at apex; surface spinulation not observed. Mesotibia with subapical comb on outer margin consisting of 5–7 densely arranged stout setae. Hind legs relatively short and robust; metatibia with 8–10 apical spurs and 10 similar spurs laterally; metabasitarsus slightly longer than broad. Male terminalia preserved only in twisted view (Fig. 101); proctiger and paramere relatively short; paramere relatively narrow and parallel-sided. Apical dilation of distal segment of aedeagus regularly widening towards a rounded apex (Fig. 102). Female proctiger and subgenital plate with short apical extensions; circumanal pore ring with two rows of pores, pores of outer row contiguous; subgenital plate, in lateral view, pointed apically. Dorsal and ventral valvulae laterally with 3–4 distinct teeth (Fig. 186). Measurements and ratios in Tabs. 2–4.

Fifth instar larva ( Fig. 252 ). Body rounded, ovoid in outline, margins of wing pads confluent with body margin. Whole body margin with pointed lanceolate setae densely arranged in one or two rows and distributed in following numbers (one side only): head in front of eyes: 27–29, cephalothorax behind eyes: 21–23, fore wing pad: 34–39, hind wing pad: 7–9, abdomen: 58–59. Dorsum of cephalothorax and fore wing pads with sparsely arranged smaller lanceolate setae, several setae also on dorsum of abdomen near margin. Antenna short, robust, situated on ventral side, oriented outwards, lacking distinct divisions, with anterior margin serrate and one or two rhinaria. Tarsal arolium nearly as large as claws. Abdomen dorsally compact, segments almost entirely fused into a large caudal plate; caudal plate margin broadly rounded. Anus in ventral position. Circumanal ring wide, with fore and hind margin close together; outer ring composed of a single row of pores, hardly sinuate. Measurements and ratios in Tab. 5.

Host plant. Carapa procera (Meliaceae) .

Biology. Unknown. Larval morphology suggests adaptation to pit gall formation.

Distribution. Senegal.

Material examined. Holotype, ♂, SENEGAL: Ziguinchor Region, Badiatte, 2 April 1984, Carapa procera (J. Etienne) . Slide-mounted [ BMNH] . Paratypes: SENEGAL: 1 ♂, 2 ♀, 7 larvae, same data as holotype ; 13 larvae, Djibelor, 17 June 1983, Carapa procera (J. Etienne) . Slide-mounted [ BMNH, NHMB] .

Etymology. Named after its host plant genus Carapa .

Comments. P. carapae is similar to P. electum , P. pretoriense , P. morion , and P. sodalis in having a dark brown infuscation along the vein Cu 1b and a similar form of apical dilation of the distal segment of aedeagus. Besides a different host plant, P. carapae is distinguished from all the four species by the shorter antennal terminal setae, the shape of female subgenital plate, and the morphology of larvae.
