Yu leg.; LFNU C202108-1 [on slide]. Paratypes: 4♀♀ [3♀♀ on slides, C202108-2-C202108-4; 1♀ destroyed for DNA extraction]; same data as holotype; LFNU.

Diagnosis.

Coccophagus breviclavulus sp. nov. can be distinguished from females of other species in this genus by the following combination of characters: scape largely white, and with two broad and short dark streaks distally (Fig. 3 View Figures 1–8 ); F2 and F3 white; mesosoma (Fig. 12 View Figures 9–16 ) most brown, with two longitudinal yellow lines medially on mid lobe of mesoscutum; metasoma largely dark brown as in Figs 9 View Figures 9–16 , 16 View Figures 9–16 ; F1 View Figures 1–8 - F3 View Figures 17–24 with the same length; clavomeres obviously wider than funicle segments.

Description.

Female. Length 0.7-0.9 mm; holotype 0.9 mm.

Colour. Head (Fig. 10 View Figures 9–16 ), in frontal view, mostly white; in dorsal view, vertex yellow, ocelli red-brown, eyes pale red and with two small dark patches behind each posterior ocellus (Fig. 9 View Figures 9–16 ). Occiput brown above foramen, and with two dark brown suboval patches lateral to foramen, the remaining parts of occiput white. Scape (Fig. 11 View Figures 9–16 ) with a dark broad streak on distal half of outer surface and on apex of ventral surface each, remainder parts white; pedicel dark brown except dorsal margin white; F1 suffused with brown, F2 and F3 white, C1 and C2 dark brown, C3 yellowish white. Mandible brown. Pronotum dark medially and white laterally; mid lobe of mesoscutum (Fig. 12 View Figures 9–16 ) mostly brown, with two longitudinal yellow line medially, lateral and posterior edges yellow; side lobe of mesoscutum largely yellow, with a brown patch anteriorly, and with interior edge dark; notaulus dark; axilla dark brown, with lateral edge yellow; mesoscutellum brown except yellow margins; metanotum brown; propodeum brown with anterior and posterior margins and lateral sides dark brown. Fore wing (Fig. 13 View Figures 9–16 ) largely infuscated and hyaline apically, with stigma vein brown; hind wing (Fig. 14 View Figures 9–16 ) hyaline. Legs (Fig. 15 View Figures 9–16 ) pale, with last tarsi brown. Metasoma (Fig. 9 View Figures 9–16 ) with petiole dark brown on anterior half part and yellow posteriorly; Gt1-Gt5 largely dark brown and yellow on posterior margin of each tergite, Gt6 and Gt7 dark brown. Ovipositor with outer plates and third valvula dark brown. Ventral part of body generally pale.

Head (Fig. 10 View Figures 9–16 ), in frontal view, 0.8-0.9 × as high as wide. Ocellar triangle with apical angle almost right-angled. Mandible tridentate. Antenna (Fig. 11 View Figures 9–16 ) with scape 2.0-2.6 × as long as wide; pedicel 1.2-1.4 × as long as wide, 1.4 × length of F1; F1-F3 ventrally connected, F1 with ventral length 1.7 × dorsal length, and as long as wide; F2 about same size as F1; F3 0.9-1.0 × as long as wide, as long as but a little wider than F1 and F2; clava with the second septum oblique, 1.2-1.4 × length of funicle, and obviously wider than funicle segment. F1 without longitudinal sensilla, other flagellomeres with the following number of longitudinal sensilla successively: 1, 2, 2, 2, 2.

Mesosoma (Fig. 12 View Figures 9–16 ). Dorsum of mesosoma finely reticulate. Mid lobe of mesoscutum with approximately 40 setae, 0.8 × as long as wide, 1.5 × length of mesoscutellum; each side lobe of the mesoscutum with 3 setae; each axilla with 3 setae; mesoscutellum 0.6 × as long as wide, with 3 pairs of setae. Distance between anterior pair of scutellar setae 0.5 × and 0.6 × that between median and posterior pair respectively. Placoid sensilla mesad of the median scutellar setae, and the distance between placoid sensilla about equal to that of anterior scutellar setae. Metanotum slightly longer than propodeum.

Wings. Fore wing (Fig. 13 View Figures 9–16 ) 2.5-2.8 × as long as wide, marginal setae long and 0.15 × wing width. Costal cell 0.8-0.9 × length of marginal vein, bearing 1 row of setae and with the distal 6 setae long and coarse; submarginal vein with 6 setae; marginal vein with 9 long setae along anterior margin; postmarginal vein absent; stigmal vein (Fig. 13 View Figures 9–16 , inset) swollen posteriorly and with sensilla arranged in 1 line. Hind wing (Fig. 14 View Figures 9–16 ) 5.5-6.6 × as long as wide, with marginal setae 0.7-0.8 × wing width.

Legs (Fig. 15 View Figures 9–16 ). Mesotibial spur as long as corresponding basitarsus.

Metasoma (Fig. 16 View Figures 9–16 ). Lateral sides of gaster, Gt6, posterior of Gt7 clearly reticulated. Setation of tergites on dorsal surface as followings: Gt2 with 2 and 3 setae (short for 2+3) on left and right side respectively, Gt3 2 or 3+2, Gt4 3+3, Gt5 4+4 or 5+5, Gt6 with 6 arranged in a line, Gt7 with 8 setae arranged in two lines. Ovipositor originating from apex of Gt3, 1.0-1.1 × as long as mesotibia, and slightly exerted. Gt7 0.3 × as long as wide. Second valvifer 1.9-2.0 × as long as third valvula; the latter 1.1-1.3 × as long as mesobasitarsus.

Male. Unknown.

Host.

Unknown.

Etymology.

The specific name refers to the scape with short streaks distally.

Distribution.

China (Xishuangbanna of Yunnan Province).

Comments.

This new species is similar to C. anchoroides but can be distinguished from the latter by the following characters: (1) scape largely white, and with two dark broad streaks distally (vs largely dark, with dorsal margin and a median streak white, cf. Fig. 5 View Figures 1–8 and fig. 90A in Huang 1994); (2) mesoscutum without the anchor shaped patch (vs with, cf. Figs 1 View Figures 1–8 , 4 View Figures 1–8 ); (3) Gt1-Gt5 with 5 brown transverse band (vs 4, cf. Fig. 8 View Figures 1–8 ); (4) funicle segments equal in length, and each segment as long as wide (vs F1 shortest, F2 and F3 longer than wide); (5) fore wing with dark setae and without narrow hyaline area posterior to marginal vein (vs with a narrow hyaline area bearing fine pale setae, cf. Fig. 5 View Figures 1–8 ); (6) ovipositor 1.0-1.1 × as long as mesotibia (vs 1.3-1.6 ×).
