Celidodacus parafenestratus Chen & Freidberg , sp. nov. ( Figs 1–10 View Figures 1–10 )

Diagnosis. C. parafenestratus Chen & Freidberg , sp. nov. is generally similar to C. obnubilus , but can be differentiated by the absence of a hyaline transverse band from the anterior to the posterior margin next to pterostigma, R 4+5 setose present till R-M and hyaline spot present in cell m ( Fig. 7 View Figures 1–10 ), and also by the slender tube connecting sac like structures of spermathecae ( Fig. 6 View Figures 1–10 ).

Description. Female, body length 5.8 mm, wing 4.0 mm.

Head ( Fig. 3 View Figures 1–10 ). Frons yellow to fulvous, length about 1.2–1.3 times of width, 1.0 times as wide as eye. Lunule yellow. Ocellar triangle dark brown and vertex yellow to fulvous. Face, parafacials and genae yellow; genae narrow, about 1/10 height of eye. Occiput yellow with upper 2/3 along eye margin usually brown. Antennal segments 1 and 2 yellow, segment 3 fuscous, ratio of length/width being 3.0–4.0, tip blunt; arista dark brown, plumose, longest rays about half width of antennal segment 3. Head setae black. Three pairs of frontals and two pairs of orbitals, lowest orbitals placed on or almost on line of highest frontals; one pair of medial vertical, lateral vertical and genal setae.

Thorax. Scutum ( Fig. 4 View Figures 1–10 ) completely yellow to fulvous with 2 narrow dark brown submedian vittae extending from anterior margin to posterior margin and 1 narrow vague gray median vitta extending from anterior margin to before level of dorsocentral bristles and 4 narrow vague gray crossbands between submedian and median vittae. Postpronotal lobes white to pale yellow. Pleura predominantly yellow to fulvous, with dorsal and posterior margins of anepisternum whitish and surrounded by a dark brown edge; katepisternum and anatergite brown; mediotergite and subscutellum dark brown. Scutellum yellow. Thoracic chaetotaxy: 2 pairs scutellar, 2 notopleural, 1 postsutural supra-alar, 1 postalar, 1 intra-alar, 2 anepisternal and 4 scapular setae, 2 prescutellar acrostichal, 2 dorsocentral setae. Wing ( Fig. 7 View Figures 1–10 ) hyaline in ground colour, with blackish brown markings as follows: a large apical patch connected with a band from stigma to anal extension, leaving hyaline indentation separately in wing apical part, cell r 1, basal part of cell cua 1 and dm, cell m, and a small hyaline spot in cell r 4+5 (sometime an additional spot in cell dm); stigma brown. Vein R 4+5 setulose to crossvein r-m. Legs yellow to fulvous, fore femora with two rows of 6–8 black spines on apical 2/5; mid femora with two rows of 14–16 black spins on apical 2/5 of each; hind femora with two rows of 14–16 black spins on apical 1/3.

Abdomen ( Fig. 5 View Figures 1–10 ). Elongate-oval in shape, generally dark brown to black, except for a yellow-white, irregularly shaped mark in middle of tergites 2 and 3; tergite 5 slightly longer than tergite 4; oviscape almost equal to length of tergites 5+6. Aculeus ( Fig. 10 View Figures 1–10 ) length/width about 3.0 times, tip ( Fig. 8 View Figures 1–10 ) blunt, with two pairs of setae (very close and resembles 1 pair if not observed carefully); 3 spermathecae ( Fig. 6 View Figures 1–10 ), each with 2 sack-like structures, bigger saccate structure round-shaped, and tube connecting two saccate structures slender.
