Makilingia siamensis n. sp.

( Figs 2 E–F, 6U–Y)

Description. Length of male 5.9 mm. Coloration. Black, unmarked except antennae and legs pale stramineous. Structure. Head produced with crown anterior margin broadly parabolic; face with frontoclypeus and anteclypeus finely shagreen and finely punctate, clypeal suture obsolete, anteclypeus in profile very slightly angulate; large punctations restricted to genae. Forewing venation relatively well delimited, without supernumerary branches or crossveins.

Male genitalia. Pygofer with ventral appendage slender with sharp, triangular ventral projection adjacent to margin of pygofer lobe, distal section extended well beyond lobe. Subgenital plate relatively long and broad, ventral margin angulately curved dorsad near base, distal section with extensive brown pigmentation, dorsal callosity bilobed. Style with preapical lobe rectangular, preapical heel very weakly developed. Aedeagus in lateral view with preatrium curved dorsad, shaft posterior margin forming right angle with preatrium, roundly expanded posteriorly, approximately as broad as long; in posterior view with atrial lobes short and evenly rounded, shaft tapered to bluntly rounded apex.

Female unknown.

Etymology. The species name refers to the type locality, Thailand (formerly Siam).

Material examined. Holotype male, THAILAND: Nakhon Si Thammarat, Namtok Yong NP, behind campground lavatory, 8°10.434'N 99°44.508'E 80m, 5–6 November 2008, U-prai K. pan trap, T3551 ( QSBG); 2 male paratypes, same data ( INHS).

Notes. The type series of this species represents the first record of the genus from Thailand as well as the first record from outside of the Philippine Archipelago. It is similar to M. nigra and M. paranigra in coloration and size but easily distinguishable by the male genitalia.
