description: 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.
