03C88793FFD4FFCAFF589856D930F91E.taxon	description	Description. Female (holotype). Body length 1.8 mm; fore wing length 2.1 mm. Head. Transverse in dorsal view, 2.0 × as wide as long and 0.9 × as wide as that of mesoscutum. Ocelli small, anterior ocellus distance from posterior ocelli. POL: OD: OOL = 0.7: 0.3: 0.8. Frons and vertex shiny, scattered with sparse small punctures and fine setae; vertex narrowed behind eyes, area behind ocellar area smooth and shiny, without setae; temple and gena feebly punctate and shiny, with dense setae; occiput slightly concave. Approximate triangular shape in anterior view, with antennal sockets high above middle level of eyes; face slightly convex, finely micro-punctate, associated with long hairs; inner margin of eyes moderately constricted at middle, more or less looking like hyperbolic curve. Antenna longer than body (12.6: 10.0); flagellomeres thin, with bristles, most flagellomeres with placodes arranged regularly in two ranks excerpt for last five or six flagellomeres. Flagellomere proportions: 2 L / W = 2.7, 8 L / W = 1.8, 14 L / W = 1.2. L 2 / 14 = 2.2, W 2 / 14 = 1.2. F 12 – 15 tightly connected. Mesosoma. Mesoscutum with spherical bulge and densely but evenly punctate and setose; notauli indistinct. Disc of scutellum also densely punctate with dense setae all over; scutellar sulcus deep with a few carinae. Propodeum highly polished, bearing a complete, median carina. Wings. Forewing without areolet, vein r almost vertically emitted from outside 2 / 5 of pterostigma; r and 2 - SR meeting at a 150 ~ 155 degree angle; 2 - SR: r: width of pterostigma = 0.8: 0.8: 0.9; vein 1 - R 1 1.3 × as long as pterostigma, pterostigma 2.1 × as long as wide. 1 - CU 1: 2 - CU 1: m-cu = 0.8: 1.1: 1.0. Hind wing narrow, vein cu-a incurved. Legs. Hind coxa small, shiny, scattered with short setae. Hind tibia approximately 0.9 × as long as hind tarsus; inner hind tibial spurs almost as long as outer one, slightly less than 0.4 × as long as hind basitarsus. Metasoma. T 1 arch, 2.3 × as long as wide, almost parallel on both sides but weakly constricted at middle and slightly wide at apical, basal half depression and smooth, with a small smooth bump at middle apex. T 2 + T 3 rectangular and wider than T 1 (1.3: 1.0), slightly constricted before the suture between T 2 and T 3, T 2 1.9 × as wide as long, T 3 1.8 × as wide as long, T 2 1.1 × longer than T 3 (1.1: 1.0), T 4 small and circular contracted at apical. T 2 + T 3 + T 4 and most T 1 almost completely covered with finely-textured and dense aciculate sculpture. Tergites posterior to T 4 concealed under it. Ovipositor short and bending downward, ovipositor sheath 0.35 × as long as hind basitarsus. Hypopygium short, strongly and evenly sclerotized. Colour. Body mostly black-brown. Antenna brown; maxillary palp, labial palp, legs and most of the ventral metasoma yellow, except for apex of metasoma dull golden; apical half of hind tibiae and hind basitarsus yellow-brown. Pterostigma and veins pale yellowish and semi-transparent. Male.

03C88793FFD4FFCAFF589856D930F91E.taxon	etymology	Etymology. The specific name “ tetratergite ” is derived from the Latin, referring to that the first four tergites of abdomen forming a reticular carapace.	en	Zheng, Min-Lin, Yang, Jian-Quan, Song, Dong-Bao (2021): A new species of Deuterixys Mason (Hymenoptera: Braconidae: Microgastrinae) from China.
