Material examined. Holotype THAILAND • ♀; Nan Province, Doi Phu Kha N.P., 19°12.283′ N, 101°04.802′ E, 1350 m, Sept. 2018, U. V. light trap, M. Raweearamwong leg. GoogleMaps

Description. Female – Length, 2.0 mm; length of antennae, 0.9 mm.

Head. Head short, transverse, head width 1.25 wider than mesosoma at tegulae. Compound eyes mediumsized, length:width ratio 1.0:0.95. Face with sparse setae ( Fig. 1B View Figure 1 ). Malar space 0.75 × eye length. Tentorio-ocular distance 2 × inter-tentorial distance. Antenna filiform, 11-segmented; length 0.33 × total body length; flagellar segment 1 (=F1) 5 × longer than wide, with 3 medioventral placodes. F2 5 × longer than wide, 3 medioventral placodes, F1 the same length as F2.

Mesosoma. Mesonotum with notauli absent, with a few sparse setae present on the dorsal region ( Fig. 1C View Figure 1 ). Mesoscutum with a pair of horn-like protuberances present on the anterior portion, and a broad groove on the outer margin of each horn ( Fig. 1A, 1C, 1D View Figure 1 ). Propodeum with a medium-sized pentagonal areola bordered by distinct carinae ( Fig. 2A View Figure 2 ). Fore wing with venation reduced, r&RS present and extending past the apex of R1 but not reaching wing margin. Pterostigma subtriangular; 1.5× as long as wide; pterostigma width 0.9 × R1 length; subdiscal cell absent. Legs slender.

Metasoma. Petiole with primary (spiracular) and secondary tubercles distinct ( Fig. 2A View Figure 2 ); 2.1× as long as width at primary tubercles; primary tubercles present at 0.4 × times total petiole length measured from anterior; secondary tubercles present at 0.8 × total petiole length measured from anterior; the distance between primary and secondary tubercles 1.2 × the width of the petiole at the primary tubercles. Petiole dorsally rugose ( Fig. 2A View Figure 2 ) with the sternite fused to tergite from the anterior portion of the petiole, past the level of the secondary tubercles, approximately 0.9 × total petiole length ( Fig. 1A View Figure 1 , 2A View Figure 2 ). Tergites 2–7 sparsely setose, smooth and shining. Hypopygial prongs elongate, narrow, and slightly arcuate with 3 elongate setae present on the dorsal surface and a single short, basally-dilated bristle at the apex ( Fig. 2B View Figure 2 ). Ovipositor sheath elongate and tapered, with two small tubercles present at the apex ( Fig. 2B View Figure 2 ).

Color. Head dark brown. Antennae with scape, pedicel, F1 and F2 light yellowish, F3 medium brown, and F4-F9 dark brown. Thorax dark brown. Wings hyaline, venation brown. Fore leg wholly yellowish with apical tarsomere brown; middle leg yellowish with apical portion of femur and tibia and apical tarsomere brown; hind leg femur dark brown, tibia brown, and apical tarsomere dark brown. Abdomen dark brown; ovipositor sheath and prongs light brown.

Male. Unknown.

Host. Unknown.

Distribution. Thailand, Nan Province.

Habitat. This specimen was collected at an ultraviolet light trap in mixed deciduous montane dipterocarp forest, in September, at the end of the rainy season.

Checklist of Aphidiinae ( Hymenoptera : Braconidae ) from Thailand

The total number of Aphidiinae now known from Thailand is 21 species from 16 genera based on surveys by Starý et al. (2008, 2010a, 2010b) and this paper. All records of Aphidiinae from Thailand are from mixed deciduous, dipterocarp, or pine forests from 230 m to 2500 m above sea level.
