1 vein Vertex Vertex-frons transition minimum width/frons maximum width Apical part of male anal tube Anal tube of male Apical extensions of phallotheca Dorsal view of flagellum C. (T.) pinivorus Strong, sharply defined at basal and apical thirds (Fig. 10) 3.03:1 Short, started close to margin of wing (Fig. 1 1) With reversed V-shaped keel (Fig. 15) 1:2.375 (males, in average) 1:2.239 (females, in average) 1:2.741 (male holotype) Oar-shaped, slightly asymmetrical (Fig. 13) Ventral part strongly arched from a lateral view (Fig. 14) Lateral extensions almost straight, only weakly arched at distal third from ventral view (Fig. 16) Slightly S-shaped to right side, without stronger medial constriction (Fig. 19) C. (T.) lineolatus Diffuse (Fig. 1) 2.94:1 Much longer, about half as long as CU1 vein itself With reversed parabolic keel (Fig. 3) Convergent into a pointed tip, bilaterally symmetrical (Fig. 4) Ventral part slightly arched towards apical part (Fig. 5) Lateral extensions strongly curved inwards (Fig. 6), right one (ventral view) with broad connecting part Medially strongly constricted, divided into two more or less triangular parts (Fig. 9) Bionomics and distribution - The type series was collected in the western Pyrenees, eastwards from Rialp, in the vicinity of the village Portainé. The collecting site was about 1600 m a.s.l. where all specimens were beaten from the same pine tree (pine species, supposedly Pinus halepensis). No further specimens were beaten from the other pines of this area nor was found in the material netted from the herb-zone. These facts suggest that this Pinus species might be the foodplant of the new planthopper species. The small number of the specimens (altogether 10 examples) may refer to the rarity of the species. The related C. (T.) lineolatus (the type species of the subgenus Tetracixius) is also a poorly known species. According to the literature (Ribaut 1960; Nasi 1972: 17; 1987: 540, 627) it has only been found in the eastern Pyrenees (type locality: Vernet-le-Bains), the type series consists of only three specimens (1 male, 1 female, 27.IV. 1959, 1 male, 3.V.1959, all specimens were collected by Dr Grave-
