Socoflata aurolineata sp. nov.
( Figs 3–10 View FIGURES 1–10 , 23–34 View FIGURES 23–28 View FIGURES29–34 , 38, 41, 42 View FIGURES35–44 , 61 View FIGURES61–67 )
Diagnosis. Socoflata aurolineata sp. nov. differs from S. histrionica sp. nov. in coloration, wax pattern, the tegmen shape and venation, the shape of the male genital style, details of the periandrium, and a smaller general size as specified in the key above.
Description. Measurements. Total length: males: 3.1–3.8 mm (mean 3.4; N = 50); females 3.3–4.1 mm (mean 3.7, N = 50). Ratios (N= 5 ♂♂, 3 ♀♀): Vertex: A/B = 1.82–2.33. Frons: C/E = 0.65–0.78, D/E = 0.96–1.10. Pronotum: F/B = 1.25–1.69. Mesonotum: G/F = 1.68–2.17, G/B+F = 1.02–1.25, G/H = 0.67–0.82. Tegmina: I/J = 3.31–3.59.
COLORATION. Vertex, pronotum and mesonotum bright orange-yellow with a well-delimited continuous median pale yellow (whitish) stripe extending from apical third of vertex to scutellum apex ( Figs 4, 6, 8, 10 View FIGURES 1–10 , 61 View FIGURES61–67 ). Frons brown, carinae lighter ochreous. Postclypeus light ochreous with its midline and ventral half darker brown; anteclypeus uniformly light ochreous; rostrum light ochreous with apex narrowly dark brown. Genae ochreous. Antennae ochreous, pedicell apically and flagellum darker brown. Compound eyes grey to reddish. Legs almost uniformly light ochreous (especially in males) to brown with carinae lighter (in females), apices of spines black. Tegmen membrane in mature specimens mostly light brown, veins and basal cell light ochreous or orange-brown, corium medially and clavus anteriorly and basally (outer claval, i.e. postcubital cell) dark brown, clavus posteriorly (inner claval, i.e. anal cell) contrastingly bright orange yellow, postclaval (commissural) margin pale yellow ( Figs 3–4, 7–10 View FIGURES 1–10 , 61 View FIGURES61–67 ). Young (teneral) specimens with tegmen almost uniformly pale dirty yellow, basal and anal cells brighter orange yellow ( Figs 5, 6 View FIGURES 1–10 ). Live specimens with tegmina extensively covered with wax, except for posterior (inner) claval cell ( Fig. 61 View FIGURES61–67 ). Hind wing membrane grey, opaque. Abdomen in males with sternites and first two visible tergites uniformly light ochreous, in females with sternites brown with light ochreous posterior margins; most tergites in both sexes extensively darker brown laterally. Male terminalia uniformly light ochreous; female terminalia mostly light ochreous, teeth on gonoplacs brown.
STRUCTURE. Body narrowly ovoid, clavus basally and bulla weakly convex, hardly outstanding of body outline ( Figs 3–10 View FIGURES 1–10 ). Tegmen venation with ScP+RA with 3–5 terminals; RP with 2–3 terminals; MP with 6–8 terminals; CuA with 3–4 terminals. Cells in medial area of tegmen mostly narrow and elongate ( Figs 27, 28 View FIGURES 23–28 ). Genital style with dorsal margin almost straight, ventral margin weakly convex, posterior margin weakly sinuate (concave in basal half), capitulum relatively long and narrow ( Fig. 38 View FIGURES35–44 ). Dorsal part of periandrium, in lateral view, with dorsal margin smoothly descending to basal part; median arm of periandrium appendage with lower process slightly curved or almost straight, not reaching the level of upper process ventral spines ( Figs 41, 42 View FIGURES35–44 ). Apex of female anal tube, in dorsal view, with a small median incision.

Vybíral leg.], [COLLECTIO Moravské museum/Brno] ( MMBC, NMPC). All paratypes are also labelled as: [PARATYPUS ♂ (or ♀)/ Socoflata / aurolineata sp. nov. /det. A. Stroiński, I. Malenovský/& D. Świerczewski 2017].
Remark. The two males from “Zemhom area” should be relabelled as from “Aloove” (see Bezděk et al. 2014).
Etymology. The specific epithet is a combination derived from the Latin noun “ aurum ” (= gold) and the adjective “ lineatus ” (= lined, striped), referring to the characteristic orange-yellow coloration of the anal cell along the postclaval margin of the tegmen.
Distribution. So far only recorded from the central part of Socotra where it is largely restricted to the Hagher mountains and the Dixam plateau. The species is especially abundant at altitudes above 1100 m a. s. l., although there are also a few records from mid-elevation plateaus.
Habitat and host plants. Socoflata aurolineata sp. nov. is one of the dominant planthopper species in the montane evergreen woodland and dwarf shrub communities on the high granite peaks in Socotra (the Leucas hagghierensis—Pittosporum viridiflorum and Helichrysum—Hypericum communities sensu Brown & Mies 2012, the latter corresponding to the Coelocarpum haggierensis—Hypericum scopulorum shrubland of De Sanctis et al.
2013; Figs 63, 64 View FIGURES61–67 ). Less abundantly, it also occurs in lower montane shrubland dominated by Cephalocroton socotranus and Croton sulcifructus. The new species is probably polyphagous on low shrubs: most specimens (including nymphs) were swept from Hypericum scopulorum (Hypericaceae; Figs 65, 66 View FIGURES61–67 ), Leucas hagghierensis ( Lamiaceae , Fig. 67 View FIGURES61–67 ), and Euryops arabicus (Asteraceae), which are probably host plants.
