A new leafhopper species of Maiestas Distant (Hemiptera: Cicadellidae: Deltocephalinae: Deltocephalini) from Thailand Author Duan, Yani Author Dietrich, Christopher H. text Zootaxa 2017 4247 1 61 64 journal article 36207 10.11646/zootaxa.4247.1.7 682fe638-e282-449b-a7d4-9bf7735505db 1175-5326 437969 B36BEEB8-F2CA-44BE-86DF-EC8D4DD4040B Maiestas serrata sp.n. ( Figs 1–2 ) Length. Male: 2.5 mm . Coloration and morphology. Ground color stramineous marked with orange and brown ( Fig. 1 A–D). Vertex, pronotum, mesonotum and scutellum with orange marks ( Fig. 1 A–C). Face mostly brown with paired white arcs corresponding to muscle scars of frontoclypeus ( Fig. 1 E). Forewing light brown with veins contrastingly pale, bordered with fuscous ( Fig. 1 A–D). Mesosternum dark brown. Femora and tibiae with fuscous marks ( Fig. 1 D). Head wider than pronotum, crown depressed, anterior margin distinctly angulate in dorsal view, nearly as long as distance between eyes ( Fig. 1 A–B); ocellus close to adjacent eye ( Fig. 1 C–D). Antenna longer than head width; anteclypeus parallel-sided, not extended to ventral margin of face; lorum semicircular, slightly narrower than anteclypeus, well separated from lateral margin of face ( Fig. 1 E). Pronotum nearly as long as vertex. Forewing macropterous, with four apical and three anteapical cells, inner anteapical cell closed basally ( Fig. 1 A–D). Male genitalia. Pygofer lobe with numerous apical macrosetae, hind margin rounded ( Fig. 2 A–B). Subgenital plate subtriangular, lateral margin weakly incurved, apex acute ( Fig. 2 C). Style with long articulatory arm, preapical lobe angulate, apophysis digitate, apex acute, slightly laterally curved ( Fig. 2 D). Connective obviously shorter than aedeagus. Aedeagal shaft elongate and very narrow, straight in lateral view with apex upturned and serrate laterally ( Fig. 2 E–F). Material examined. Holotype : male, pinned, with genitalia in a separate microvial, Thailand : Ubon Ratchathani Pha Taem NP Rong Hi Noy , 15° 40′ 021" N, 105° 30′ 440" E, 240 m , malaise trap , 1–7 i 2007 , Thongkam & Pakdee , leg. T1476 ( QSBG ) . Paratype : 1 male , pinned, with genitalia in a separate microvial, Thailand : Ubon Ratchathani Pha Taem NP Khua Nang Nee , 15° 24′ 285" N, 105° 30′ 855" E, 193 m , malaise, 24 ii–3 iii 2007 , Bunlu Subsiri , leg. T1674 ( INHS ) . Remarks. This species will run to M. oryzae (Matsumura) in the key of Zhang & Duan (2011) and resembles that species in having the inner anteapical cell of the forewing closed, the pygofer lobe rounded and the aedeagus somewhat elongated and lacking a heel at the base of the shaft. It is also similar to M . scalpella Zhang & Duan and M . chalami Zahniser, McKamey & Dmitriev in the shape of the aedeagus but differs from the former in having the forewing without a dark brown spot and the inner anteapical cell closed basally ( Fig. 1 A–D), the subgenital plate shorter ( Fig. 2 C), the apex of the style more acute ( Fig. 2 D), and the connective shorter; and from the latter in having the vertex and forewing without dark brown maculations ( Fig. 1 A–D). Etymology. The specific epithet is based on the apical serrated lateral margins of the aedeagal shaft.
