Pseudophacopteron hollisi sp. nov.

( Figs. 60, 66 , 81 , 157–159, 169, 219–220, 227)

Description. Adult. Colour. Vertex orange brown, midline and anterior tubercles pale yellow ( Fig. 66 ). Genae pale yellow with a brown transverse streak; frons orange brown; clypeus pale yellow. Pronotum orange brown, midline and lateral tubercles pale yellow. Mesopraescutum orange brown, midline basally pale yellow. Mesoscutum orange brown with three narrow stripes medially and lateral corners pale yellow. Mesoscutellum, metascutum, metascutellum and metapostnotum mostly orange brown with small yellow markings. Lateral sclerites of thorax dark brown with pale yellow markings. Antenna yellow, segments 1–2 brown basally, segments 3–8 narrowly dark brown apically, segments 9–10 entirely dark brown to black. Legs dirty yellow; metacoxa and metafemur with extensive dark brown markings; fore and mid femora with dark brown streaks near apex and base; tibiae entirely yellow or weakly infuscated at base. Fore wing membrane clear, transparent, with brown patches around apical parts of veins Rs, M, M 3+4, Cu 1a, Cu 1b, M fork and touching point of Rs and M 1+2 ( Fig. 60 ). Veins pale yellow, except for C+Sc brown in basal two thirds, dark brown spots on apices and forks of all other veins, a spot in middle of vein R+M+Cu 1, and two spots medially on apical portion of Rs, M 1+2, M 3+4, Cu 1a, and anal vein. Hind wing membrane clear, transparent; vein C+Sc light brown. Abdominal tergites mostly orange brown, sometimes narrowly dark brown posteriorly. Sternites pale yellow, two first visible segments extensively dark brown to black laterally, third and fourth segments lighter brown, each with a pale yellow spot within dark patches. Male terminalia with subgenital plate brown, proctiger pale yellow, brown basally; parameres orange brown. Female terminalia with proctiger orange brown to brown; subgenital plate yellow basally, dark brown apically.

Morphology. Vertex with two large anterior tubercles in front, slightly raised midline dorsally, lacking distinct tubercles laterally ( Fig. 66 ). Median epicranial suture distinct in basal and apical fifths. Genae below toruli swollen and blunt. Antenna slender, segments cylindrical, weakly widening to apex; two rhinaria subapically on each of segments 4–8 (similar in structure to P. caffrariense ), one rhinarium on segment 9; terminal setae strongly differring in length, the shorter seta rudimentary, the longer seta shorter than segments 9 and 10 together ( Fig. 227 ). Fore wing with fine surface spinulation present in cells cu 1, cu 2, m 1, m 2 and apical part of r 2 ( Fig. 81 ). Mesotibia with subapical comb on outer margin consisting of 4–6 stout setae. Metatibia with 12 apical spurs. Metabasitarsus relatively short, conical, lacking distinct sclerotised spurs (Fig. 169). Male subgenital plate, in lateral view, with dorsal margin raised in basal third, sinuate (Fig. 157). Male proctiger, in lateral view, slender. Paramere large, longer than proctiger; in lateral view, chisel-shaped, constricted medially, apex broadly truncate (Fig. 158). Distal segment of aedeagus as in Fig. 159. Female proctiger and subgenital plate with short apical extensions ( Fig. 219 ); subgenital plate, in lateral view, with ventral margin strongly convex and apex blunt; in ventral view, broadly rounded with U-shaped indentation at apex ( Fig. 220 ). Ventral margin of ventral valvulae finely serrate apically ( Fig. 219 ). Measurements and ratios in Tabs. 2–4.

Larva unknown.

Host plant. The type series was collected on Lecaniodiscus sp. (Sapindaceae) , a probable host plant.

Biology. Unknown.

Distribution. Kenya.

Material examined. Holotype, ♂, KENYA: Arabuko-Sokoke Forest Reserve , Jilore track, ca. 150 ft, 2–3 June 1974, beaten from Lecaniodiscus sp. (D. Hollis) . Dry-mounted [ BMNH] . Paratypes: KENYA: 1 ♂, 8 ♀, same data as holotype. Dry- and slide-mounted [ BMNH, MMBC, NHMB] .

Etymology. Named in honour of David Hollis, the collector of the type series.

Comments. P. hollisi is similar to P. caffrariense in the fore wing shape and pattern, the form of genae, the number and structure of rhinaria on antenna, as well as the absence of sclerotised spurs on metabasitarsus. It differs from P. caffrariense in the raised midline of the vertex, the reduced median epicranial suture, the absence of lateral tubercles on the vertex, the separated brown patches on veins Rs and M 1+2 of the fore wing, the coloration of head, thorax and sternites, and the shape of paramere and female terminalia.
