Maiestas subsirii Duan sp. n.

( Figs 5–6 )

Length. Male: 3.6 mm.

Coloration and morphology. Pale yellow with brown marks. Crown with one brown dot on either side of median line on anteriorly, with three light brown patches ( Fig. 5A ). Face with paired white arcs on frontoclypeus ( Fig. 5C ). Pronotum with six light brown longitudinal bands. Mesonotum with central area and basal triangles light brown ( Fig. 5A ). Forewing brownish hyaline contrasting with white marking on veins; with a dark brown patch at middle of claval suture and another patch at m-cu1 ( Fig. 5A–B ). Legs with setal bases brown ( Fig. 5B ). Crown wider than pronotum. Crown depressed, anterior margin distinctly angulate in dorsal view, as long as distance between eyes ( Fig. 5A ). Anteclypeus tapering, not extended to ventral margin of genae ( Fig. 5C ). Forewing with numerous extra cross veins and four apical and three suabapical cells, inner subapical cell closed basally; appendix narrow ( Fig. 5A–B ).

Male genitalia. Pygofer with posterior lobes moderately long and equilateral triangle; with numerous macrosetae ( Fig. 6A ). Subgenital plate subtriangular, lateral margin concave; with few lateral macrosetae ( Fig. 6C ). Style basal arms widely separated, articulating arm moderately long, lateral arm short; preapical lobe well developed, broadly triangular; apophysis relatively short and slim, slightly laterally curved ( Fig. 6D ). Connective nearly as long as aedeagus, linear with arms joined distally. Aedeagus with shaft short, slightly curved dorsally; without processes; with ventral margin extending beyond gonopore; gonopore subapical on dorsal surface ( Fig. 6E–F ).

Material examined. Holotype: male, Thailand: Ubon Ratchathani Pha Taem NP Don Rong pond, 15°24.582′N, 105°30.935′E, 250 m, Malaise trap, 3–10 ii 2007, Bunlu Subsiri, leg. T1664 ( QSBG).

Etymology. This species is named for Bunlu Subsiri who collected the type specimen.

Remarks. Externally, this species resembles Maiestas pruthii (Metcalf) , M. parapruthii (Chalam & Rao) and M. menoni (Rao & Ramakrishnan) in having numerous extra cross veins in the forewing, but the latter three species have noticeably fewer cross veins and differ in the structure of the pygofer and aedeagus. Some other genera of Deltocephalini , including the two new genera described here, Matsumuratettix Metcalf and Polyamia DeLong , also have supernumerary forewing cross veins.
