Zhi-Shan Wu), by sweeping; 1 ♀, China: Fujian, Fuzhou, Forest Park, 5 November 1989 (coll. Jian-Qing Huang), by yellow sticky trap, ( FAFU). Additional specimen, 1 ♀, China: Fujian, Fuzhou, Jinshan, 30 September 2013 (coll. Zhu-Hong Wang), ex. diaspidid scale on bamboo.

Female. Body length: 0.59 (0.65–0.79) mm.

Colour. Head and mesosoma dark brown, metasoma pale yellow; mandible dark brown to black brown. Antenna with basal three-fifths of scape dark brown, apex of scape pale brown, pedicel and flagellum pale yellow. Wings hyaline. Legs pale yellow, fore coxae dark basally and hind coxae slightly darkened basally. Third valvula pale yellow.

Head. Vertex with reticulate sculpture; eyes finely setose; Antennal scape about 3.78× (3.57–4.00×) as long as wide; pedicel 1.50× (1.40×) as long as wide, 0.89× (0.87–0.90×) as long as F1; F1 subequal in length to F2, 0.88× (0.89×) as long as F3; F1–F3 2.00×, 1.78× and 1.73× as long as wide respectively, each with 2 or 3 longitudinal sensilla; clava shorter than funicle; C1 1.32× (1.47–1.54×) as long as wide, subequal in length to F3; C2 2.05× (2.36–2.66×) as long as wide, 1.54× (1.44–1.78×) as long as C1, each with 3 or 4 longitudinal sensilla.

Mesosoma. Mid-lobe of mesoscutum mostly with irregularly hexagonal cells or reticulation, except transverse reticulation posterolaterally, with 22 (14–20) setae; distance between axillae 2.82× (3.00×) length of an axilla; mesoscutellum 0.75× (0.86×) as long as mid–lobe of mesoscutum, with longitudinal reticulation medially and irregularly hexagonal cells or reticulation laterally, with 2 pairs of setae, and placoid sensilla closer to fore pair of setae than to hind pair; metanotum with faint reticulation medially; propodeum reticulate except faint medially; mesopostphragma, measured from apex of mesoscutellum, 1.39× (1.11–1.32×) as long as mesoscutellum. Fore wing 3.04× (3.03–3.35×) as long as maximum width of wing disc; marginal fringe 0.35× (0.26–0.35×) as long as maximum width of disc; submarginal vein shorter than marginal vein, with 7 (7 or 8) setae; marginal vein with 9 (8 or 9) setae along anterior margin; postmarginal vein absent; wing disc densely setose with narrow asetose area posterobasally.

Metasoma. Metasoma slightly shorter than mesosoma; tergites 1–7 with setae as follows: T1–T4, 1+1 each; T5, 2+2; T6, 4 between cercal plates; T7, 7 in two rows; ovipositor basally located at T3, slightly projecting beyond apex of metasoma, 1.41× (1.42×) as long as mid tibia, third valvula 1.94× (1.47–1.57×) as long as mid basitarsus.

Male. Unknown.

Host. An unidentified Diaspididae (Hemiptera) scale on bamboo.

Distribution. China (Fujian).

Diagnosis. Coccobius abdominis differs from other species of the genus by the head and mesosoma being dark brown and the metasoma completely pale yellow in combination with the antennal pedicel and flagellum being pale yellow.
