Pseudophacopteron wagneri View in CoL sp. nov.

(Figs. 11–12, 26, 48, 76, 136–138, 203–204, 243)

Description. Adult. Colour (ethanol preserved specimens). Head, thorax and abdomen almost uniformly dirty yellow or ochreous. Antenna dirty yellow, segments 3–8 narrowly infuscated light brown apically, segments 9–10 entirely dark brown to black. Legs dirty yellow, metafemur narrowly dark brown apically. Fore wing membrane clear, transparent anteriorly in outer half, infuscated dark brown basally along vein R+M+Cu 1, yellow at base of cell cu 2 and across veins Cu 1, M+Cu 1 and R; a dark brown band bordered yellow extending along posterior wing margin from vein Cu 1b to wing apex in cell r 2, leaving small triangular transparent areas at wing margin in cu 1, m 1 and m 2 ( Fig. 48 View FIGURES 39–48 ). Veins dirty yellow except for brown C+Sc, a dark brown spot on R+M+Cu 1 fork and two dark spots on anal vein. Hind wing membrane infuscated brown basally. Male and female terminalia dark brown, female subgenital plate basally dirty yellow.

Morphology. Head, in frontal view, dorsoventrally flattened, about three times wider than high; vertex smooth and shiny, lacking distinct microsculpture, flat dorsally, lacking median ridge except for a hardly distinct rudiment in front (Fig. 12); lateral ocelli lying in the plane of vertex; vertex regularly rounded down in front, lacking anterior tubercles or bulges; eyes subangular; genae with tubercles below toruli blunt apically (Figs. 11–12). Antenna relatively short and robust, segments distinctly widening to apex; terminal setae subequal, short, the longer terminal seta about as long as segments 9 and 10 together ( Fig. 243 View FIGURES 230–246 ). Fore wing elongate, apex narrowly rounded; surface spinulation present in cells cu 1, cu 2, m 1, m 2, apical portion of r 2 and a few spinules present also in c+sc and basal portion of r 2 ( Fig. 76 View FIGURES 67–76 ). Mesotibia with subapical comb on outer margin reduced to 2–3 stout setae. Hind legs relatively short and robust; metatibia with 6–7 relatively sparsely arranged apical spurs and 1–3 similar, stout but more slender setae laterally; metabasitarsus short, about as long as broad, subglobular ( Fig. 26 View FIGURES 23–28 ). Male proctiger, in lateral view, relatively long and slender (Fig. 136). Paramere slightly shorter than proctiger, in lateral view, relatively slender and straight, anterior margin slightly concave subapically and narrowing towards subacute apex, forming a small tooth (Fig. 137). Distal segment of aedeagus with relatively short shaft and large apical dilation which is slightly hooked and broadly rounded apically (Fig. 138). Female proctiger and subgenital plate with relatively short apical extensions; dorsal margin of proctiger concave; circumanal pore ring with two rows of pores, pores of outer row spaced; subgenital plate, in lateral view, blunt apically (Fig. 203); in ventral view, broad basally and narrowing to truncate apex (Fig. 204). Dorsal valvulae lacking distinct lateral teeth; ventral valvulae with 3–5 teeth subapically (Fig. 203). Measurements and ratios in Tabs. 2–4.

Fifth instar larva unknown.

Host plant. The adults of the type series were collected on Tabernaemontana stapfiana (Apocynaceae) which could be the host plant.

Biology. Unknown.

Distribution. Kenya, Mozambique.

Material examined. Holotype, ♂, KENYA: Gatamayu, Kikuyu Escarpment, 0°58’S, 36°42’E, 2330 m, 18–23 January 1999, mountain forest ( Podocarpus –Croton type), Tabernaemontana stapfiana , canopy fogging (T. Wagner). Slide-mounted [ NHMB]. Paratypes: KENYA: 1 ♂, 4 ♀, same data as holotype. Dry- and slide-mounted and preserved in ethanol [ MAKB, MMBC, NHMB].

Material not included in the type series: MOZAMBIQUE: 1 ♂, Lourenço Marques (= today Maputo), August 1973, yellow trap (M. A. Grouveia). Slide-mounted [ BMNH] .

Etymology. Named in honour of the German coleopterologist and ecologist Thomas Wagner, the collector of the type series.

Comments. P. wagneri is similar to P. nigritulum in the flat head lacking a median ridge, the elongate fore wing with a narrowly rounded apex, the small number of lateral spurs on the metatibia, and the male and female terminalia. It differs from P. nigritulum in the coloration of body, the fore wing pattern, the dorsoventrally flattened head, the relatively shorter antenna, the relatively shorter metatibia and metabasitarsus, the shape of the male paramere, as well as the relatively shorter female terminalia.
