A review of the Afrotropical jumping plant-lice of the Phacopteronidae (Hemiptera: Psylloidea) Author Malenovský, Igor Author Burckhardt, Daniel text Zootaxa 2009 2009-04-29 2086 1 1 74 https://biotaxa.org/Zootaxa/article/view/zootaxa.2086.1.1 journal article 10.11646/zootaxa.2086.1.1 1175­5334 5310382 Pseudophacopteron zimmermanni -group Head, in dorsal view, slightly wider than mesonotum. Vertex with a raised median ridge dorsally (Figs. 1–8), rudimentary or absent in some species (Figs. 9–12); in many species, bulges or tubercles are present on both sides of median ridge (Figs. 1–4, 7–8) or vertex is more or less flat and regularly rounded down in front (Figs. 5–6, 9–12); lateral ocelli usually lying on small tubercles above the plane of vertex or more or less in its plane; median epicranial suture absent; lateral tubercles absent. Occiput and preoccipital sclerite narrow; eyes not stalked, subglobular (Figs. 1–4, 7–10) or more extended, eyes slightly stalked, subangular (Figs. 6, 11–12). Genae relatively small, produced anterio-laterally into a tubercle below torulus, which is narrow and more or less acute at apex and oriented laterally away from frons (Figs. 1, 3, 5–7, 9, 11). Frons narrow, nearly parallelsided. Clypeus subglobular. Antenna with a single widely elliptic rhinarium near apex of each of segments 4–9, bordered with a wreath of cuticular spines ( Figs. 17–18 ). Fore wing relatively broad, pyriform, with apex truncate or broadly rounded (e.g. Figs. 29–46 ) or narrow, elongate and narrowly rounded apically ( Figs. 47–48 ); radular spinules present in small triangular patches in both apical corners of cells m 1 and m 2 and proximal apical corners of r 2 and cu 1 . Mesotibia with a comb of 2–12 more or less densely arranged stout setae on outer margin subapically. Metacoxa with right-angled posterior margin and small, acute, thorn-like meracanthus; metafemur constricted medially ( Fig. 28 ); metatibia with an open crown of unsclerotised apical spurs ( Figs. 23, 26 ) and ca. 1–15 similar spurs laterally arranged usually in two irregular rows ( Figs 23–24 ). Metabasitarsus relatively long and cylindrical or conical ( Figs. 23, 28 ) or short and subglobular ( Fig. 26 ), bearing two black lateral sclerotised spurs subapically. Male subgenital plate with dorsal margin nearly straight. Male proctiger cylindrical. Paramere simple, lamellar, more or less straight and parallel-sided. Distal segment of aedeagus with a relatively broad apical dilation, rounded, pointed or hooked at apex; sclerotized end tube of ductus ejaculatorius sinuate. Female circumanal ring with one ( Figs. 192–193, 196 ) or two rows of pores. Dorsal and/or ventral valvulae in most species with distinct lateral teeth. Larva with a large (e.g. Figs. 247–248 ) or small ( Figs. 257–258 ), short and broad tarsal arolium lacking distinct petiole; circumanal pore ring situated ventrally ( Figs. 247–255 , 259–261 ) or apically and slightly extending on ventral side of abdomen ( Figs. 256–258 ). Comments . The group is defined by the following adult characters: the form of genal tubercles which are relatively small, narrow and acute at apex and oriented dorsolaterally away from frons, the absent median epicranial suture of the vertex, the presence of lateral spurs on the metatibia, and the medially constricted metafemur. Currently the group includes 26 Afrotropical species.
