Pseudophacopteron lautereri
sp. nov.
(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

; wing base indistinctly irregularly infuscate (

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
). Fore wing pyriform, apex truncate; surface spinules present in all cells (
Fig. 71
). 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
); in ventral view, rectangular with acute apical extension (
Fig. 191
). Dorsal valvula lacking distinct lateral teeth, ventral valvula laterally with a few (2–3) fine teeth near apex (
Fig. 190
). Measurements and ratios in Tabs. 2–4.
Fifth instar larva unknown.

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
.
