Treatment

Pseudophacopteron marmoratum View in CoL sp. nov.

( Figs. 41 View FIGURES 39–48 , 72 View FIGURES 67–76 , 115–117, 192, 239, 259)

Description. Adult. Colour. Head and thorax in males almost uniformly dark brown, in females light to dark brown with midline, anterior tubercles on vertex, lateral ocellar tubercles and lateral tubercles on pronotum all pale ochreous. Lateral sclerites of thorax dark brown in both sexes. Antenna off-white, segments 3–4 narrowly infuscated light brown apically, segments 5–8 narrowly dark brown apically, segments 9–10 entirely black. Legs pale ochreous with dark brown markings. Fore wing membrane light ochreous, with dark pattern consisting of many small brown spots, densely arranged and forming confluent patches especially in fore wing outer half along posterior margin, vein Cu 1b and apex of vein Rs, leaving small transparent areas at wing margin in cells cu 1, m 1 and m 2 ( Fig. 41 View FIGURES 39–48 ). Veins ochreous, except for dark brown C+Sc, spots in the middle of vein R+M+Cu 1 and on its fork, in basal third of R, on M+Cu 1 fork, on touching point of Rs and M 1+2 and two spots on anal vein. Hind wing clear, transparent, vein C+Sc dark brown. Abdominal tergites dark brown, red brown on dorsum. Sternites entirely dark brown or lighter in the middle. Male terminalia ochreous. Female terminalia light to dark brown, apical extension of female proctiger dark.

Morphology. Vertex with coarse microsculpture, matt; narrow and relatively weakly raised median ridge distinct especially in anterior part of vertex; a tubercle on either side of median ridge present near anterior vertex margin on transition to frons; genae with tubercle below torulus relatively small and blunt apically (conditions similar to P. verrucifrons as figured by Burckhardt & Mifsud 1998 and Burckhardt & van Harten 2006). Antenna relatively robust, slightly serrate, segments short and distinctly widening to apex; terminal setae short, the longer seta nearly as long as or shorter than segments 9 and 10 together and 1.5 times or twice longer than the shorter seta ( Fig. 239 View FIGURES 230–246 ). Fore wing pyriform, apex broadly rounded; surface spinulation coarse and dense, present in all cells and leaving no spinules-free areas ( Fig. 72 View FIGURES 67–76 ). Mesotibia with subapical comb on outer margin consisting of 3–4 stout setae. Metatibia with 8 relatively sparsely arranged apical spurs and six similar or slightly more slender spurs laterally. Metabasitarsus distinctly longer than broad. Male proctiger, in lateral view, relatively long and narrow (Fig. 115). Paramere relatively short, in lateral view, with anterior margin slightly convex and posterior margin nearly straight, apical part narrowly rounded, with a blunt apical tooth; paramere inner side covered with fine setae (Fig. 116). Apical dilation of distal segment of aedeagus hooked, apex broad and truncate, dorsal margin basally angular (Fig. 117). Female proctiger and subgenital plate with moderately long apical extensions; proctiger dorsal margin concave, circumanal pore ring composed of a single row of pores; subgenital plate, in lateral view, with apex subacute ( Fig. 192 View FIGURES 188–200 ), in ventral view, similar to P. verrucifrons as in Fig. 194 View FIGURES 188–200 but relatively shorter and broader. Dorsal valvulae lacking distinct teeth, ventral valvulae laterally with 3–6 pairs of fine teeth ( Fig. 192 View FIGURES 188–200 ). Measurements and ratios in Tabs. 2–4.

Fifth instar larva ( Fig. 259 View FIGURES 259–262 ). Body robust. Body margin with 13–16 large blunt lanceolate setae on caudal plate apex; dorsum of body and margins of cephalothorax, wing pads and abdomen with sparse inconspicuous minute simple setae. Antenna straight, directed obliquely forwards, short, with 7–9 distinct segments and two rhinaria. Tarsal arolium as large as claws. Abdomen dorsally with five free sclerites and fused caudal plate; caudal plate margin broadly rounded. Anus in ventral position. Circumanal ring small, with fore and hind margin widely separated; outer ring composed of a single row of pores, not sinuate. Measurements and ratios in Tab. 5.

Host plant. Commiphora africana (Burseraceae) .

Biology. Larvae are free-living and ant-attended. No galls were observed on the host-plant (J. Martin, pers. comm.).

Distribution. Kenya.

Material examined. Holotype, ♂, KENYA: Namanga, S slope of Ol Doinya Orok , ca. 5500 ft, 5–6 June 1974, beaten from Commiphora africana (D. Hollis) . Dry-mounted [ BMNH] . Paratypes: KENYA: 3 ♂, 11 ♀, same data as holotype ; 6 ♂, 12 ♀, 17 larvae, Westermann’s Safari Camp , 30 km S of Voi, 21 May 1988, on Commiphora africana var. glaucidula (J. H. Martin) . Dry- and slide-mounted [ BMNH, MMBC, NHMB] .

Etymology. From the Latin adjective marmoratus = marbled, referring to its forewing colour pattern.

Comments. P. marmoratum appears close to P. arcuatum and P. verrucifrons with which it shares a similar head morphology, antennal terminal setae, male and female terminalia, particularly the circumanal ring consisting of a single row of pores. All three species occur sympatrically in Kenya on the same host plant. P. marmoratum differs from P. arcuatum and P. verrucifrons in the fore wing pattern and surface spinulation as well as in the narrowly rounded apex of paramere in lateral view and the relatively shorter female terminalia.
