(Figs. 3–4, 40, 71, 106–111, 190–191, 238)

Description. Adult. Colour (ethanol preserved specimens). Body ochreous. Head with vertex ochreous to orange brown laterally, median ridge, genae, frons and clypeus paler. Pronotum dark brown laterally, lateral tubercles light. Mesopraescutum with two triangular dark brown macules in anterior two thirds. Mesoscutum often with four dark bands and pale ochreous midline. Mesoscutellum, metascutum, metascutellum and metapostnotum light ochreous to off-white. Lateral sclerites of thorax dark brown. Antenna pale ochreous, segment 3 narrowly infuscated light brown apically, segments 4–8 narrowly dark brown apically, segments 9–10 entirely black. Legs ochreous, metacoxa dark brown, profemur and mesofemur with dark brown streaks near apex and base, metafemur almost entirely dark brown, only lighter apically, metatibia dark brown basally. Fore wing membrane clear, transparent, with dark brown pattern consisting of a band along distal half of posterior margin (from distal half of cell cu 1 to the posterior tip of cell r 2, leaving two small transparent crescents at wing margin in m 1 and m 2), large patches adjacent to veins R 1, basal two thirds of R, and apical part of Rs, smaller patches along Cu 1b, across medial part of M and on touching point of Rs and M 1+2; wing base indistinctly irregularly infuscate ( Fig. 40 View FIGURES 39–48 ). Veins light ochreous, except for C+Sc, basal three quarters of R, and dark brown spots or portions in the middle of veins R+M+Cu 1, M, M 3+4, Cu 1a, on the M+Cu 1 fork, M fork and Cu 1 fork, the touching point of Rs and M 1+2, apices of Cu 1a and Cu 1b, and two spots on anal vein. Hind wing clear, transparent, vein C+Sc dark brown. Abdominal tergites ochreous to orange brown, laterally and on tubercles on dorsum darker brown. Sternites dark brown. Male terminalia with subgenital plate and base of proctiger dark brown, apex of proctiger paler ochreous and parameres rusty brown. Female terminalia brown, subgenital plate lighter apically.

Morphology. Head similar to P. zimmermanni (Figs. 3–4). Antenna relatively slender, segments cylindrical, weakly widening to apex; terminal setae markedly differring in length, the longer terminal seta approximately three times longer than segments 9 and 10 together and twice longer than the shorter seta ( Fig. 238 View FIGURES 230–246 ). Fore wing pyriform, apex truncate; surface spinules present in all cells ( Fig. 71 View FIGURES 67–76 ). Mesotibia with subapical comb on outer margin consisting of 9–12 densely arranged stout setae. Metatibia with 12–15 apical spurs and 10–15 similar spurs laterally; metabasitarsus slightly longer than broad. Male proctiger, in lateral view, relatively long and narrow (Figs. 106, 109). Paramere long and slender, in lateral view, straight, nearly parallel-sided, with apical tooth situated posteriorly (Figs. 107, 110). Apical dilation of distal segment of aedeagus hooked and acute at apex (Figs. 108, 111). 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, with ventral margin strongly convex, subapically broad, apex acute ( Fig. 190 View FIGURES 188–200 ); in ventral view, rectangular with acute apical extension ( Fig. 191 View FIGURES 188–200 ). Dorsal valvula lacking distinct lateral teeth, ventral valvula laterally with a few (2–3) fine teeth near apex ( Fig. 190 View FIGURES 188–200 ). Measurements and ratios in Tabs. 2–4.

Fifth instar larva unknown.

Host plant. Unknown. Most of the type series was collected on Rinorea beniensis (Violaceae) , an unlikely host plant.

Biology. Unknown.

Distribution. Uganda.

Material examined. Holotype, ♂, UGANDA: District Masindi, Budongo Forest near Sonso, 1°45’N, 31°25’E, 1200 m, 19–30 June 1995, canopy fogging, seasonal rain forest, Rinorea beniensis (Violaceae) , secondary forest (T. Wagner). Dry-mounted [ NHMB]. Paratypes: 1 ♂, 1 ♀, same data; 8 ♂, 3 ♀, same data but 1–10 July 1995; 3 ♂, 1 ♀, same data but 11–20 July 1995; 1 ♂, 1 ♀, same data but 21–30 July 1995; 7 ♂, 4 ♀, same data but 5–15 January 1997; 3 ♂, 4 ♀, same data but 15–25 January 1997, secondary forest and swamp forest; 1 ♀, same data but 19–30 June 1995, Trichilia rubescens (Meliaceae) ; 1 ♂, 1 ♀, same data but 15–25 January 1997, primary forest, Cynometra alexandri (Fabaceae) . Dry- and slide-mounted and preserved in ethanol [ BMNH, MAKB, MMBC, MHNG, NHMB].

Etymology. Named in honour of the Czech entomologist and expert in Psylloidea Pavel Lauterer on the occasion of his 75th birthday.

Comments. P. lautereri is similar to P. lecaniodisci in size, fore wing pattern, the asymmetrical length of the antennal terminal setae, and the form of the male and female terminalia. P. lautereri differs from P. lecaniodisci in the longer paramere and distal segment of aedeagus, the straight paramere and the apically broader female subgenital plate in lateral view.

There is variation in the shape of paramere in the material of P. lautereri examined. Some specimens have narrower paramere (Figs. 106–107), while others have the paramere including its apex slightly broader (Figs. 109–110). We interpret this as intraspecific variation but more material, including larvae, and reliable data on host plant(s) and biology are needed. Figs. 106–107 depict the condition in the holotype.
