Coccobius jinshanensis Wang, Huang & Polaszek , sp. nov.

( Figs 38–46 )

Type material. Holotype female. China: Fujian, Fuzhou, Jinshan, June 2013 (coll. Yan-Hua Li), ex. a diaspidid scale ( Hemiptera : Diaspididae ) on bamboo. Deposited as a slide-mounted specimen in College of Plant Protection, Fujian Agriculture and Forestry University, Fuzhou, China ( FAFU).

Female. Body length: 0.81 mm.

Colour. Head mostly brown to blackish brown except frontovertex dark yellow; mandible dark brown. Pronotum and axilla dark to blackish brown; mid-lobe of mesoscutum dark yellow with a dark brown patch on each side and a short dark brown stripe in posterior half centrally; side-lobe of mesoscutum dark yellow to dark brown; mesoscutellum mostly dark yellow with margins brown to dark brown; metanotum and propodeum brown to dark brown except middle white; prosternum and mesopleuron dark to blackish brown; mesosternum and metasternum mostly yellow. Metasoma pale yellow with rather sharply defined blackish brown bands on each side from the base to cercal plates. Antenna with radicle, basal half of scape, F1 and clava brown to dark brown; apical half of scape, pedicel, F2 and F3 pale yellow. Wings hyaline. Legs white to pale yellow. Third valvula pale yellow.

Head. Vertex with reticulate sculpture; eyes finely setose. Antennal scape about 3.50× as long as wide; pedicel 1.80× as long as wide, subequal in length to F1; F1 2.14× as long as wide, 0.85× and 0.82× as long as F2 and F3 respectively, F2 2.30× as long as wide, slightly shorter than (0.96× as long as) F3, F3 2.20× as long as wide, each funicular segment with 1 or 2 longitudinal sensilla; clava slightly shorter than (0.97× as long as) funicle, C1 2.70× as long as wide, C2 3.50× as long as wide, distinctly longer than (1.53× as long as) C1, each claval segment with 2– 4 longitudinal sensilla.

Mesosoma. Mid-lobe of mesoscutum with faint reticulation, with 44 setae; distance between axillae about 2.9× length of an axilla; mesoscutellum 0.90× as long as mid-lobe of mesoscutum, with distinctly longitudinal reticulation and with 3 pairs of setae, placoid sensilla close to mid pair of setae; mesopostphragma, measured from apex of mesoscutellum, subequal in length to mesoscutellum. Fore wing 2.70× as long as maximum width of wing disc; marginal fringe short, 0.15× as long as maximum width of wing disc; submarginal vein shorter than marginal vein, with 7 setae; marginal vein with 11 setae along anterior margin; postmarginal vein absent; wing disc densely setose with narrow asetose area posterobasally.

Metasoma. Metasoma subequal in length to mesosoma; tergites 1–7 with setae as follows: T1, 1+1; T2, 4+3; T3, 4+4; T4, 4+4; T5, 3+3; T6, 5 between cercal plates; T7, 12 in three rows; ovipositor basally located at T3, slightly projecting beyond apex of metasoma, 1.70× as long as mid tibia; third valvula 3.20× as long as mid basitarsus.

Male. Unknown.

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

Distribution. China (Fujian).

Etymology. The specific designation jinshanensis is derived from the place name, Jinshan area, where the new species was collected.

Diagnosis. Coccobius jinshanensis resembles C. maculatus Huang 1994 , which keys to couplet 14 in the key to Chinese species given by Wang et al. (2014), but can be differentiated from the latter by the following: head with frontovertex dark yellow; mid-lobe of mesoscutum dark yellow with a dark brown patch on each side and a short dark brown stripe in posterior half medially; mesoscutellum mostly dark yellow with margins brown to dark brown; and antenna with flagellum relatively slender, F1–F3 2.14–2.30× and C1–C2 2.7–3.50× as long as wide respectively, F1 shorter than (0.85× and 0.82× as long as) F2 and F3 respectively. In C. maculatus the head, midlobe of mesoscutum and mesoscutellum are dark brown and the flagellum is not slender, with F1–F3 1.50–1.92× and C1–C2 1.35–2.33× as long as wide respectively, and F1 longer than (1.10× as long as) F2 and F3 respectively.

Coccobius jinshanensis also resembles C. aligarhensis Hayat 1974 , but can be differentiated from the latter by the following: the mesoscutellum mostly dark yellow; antenna with radicle, basal half of scape, F1 and clava brown to dark brown; apical half of scape, pedicel, F2 and F3 pale yellow. In C. aligarhensis the mesoscutellum has a large dark brown patch on each side and the scape is brown except its apex and the remainder of the antenna is pale yellow.
