7. Coeliccia galbina Wilson & Reels, 2003 View in CoL

( Figs 14d View FIGURE 14 , 16d View FIGURE 16 , 17d View FIGURE 17 , 19d View FIGURE 19 , 20d View FIGURE 20 , 21c View FIGURE 21 , 22e View FIGURE 22 , 28a View FIGURE 28 )

Specimens examined. 1 ♂, Huu Lien NR, Lang Son Prov. (appr. 21.660N, 106.371E; alt. 270 m asl.), 19 x 2014, TK leg; 1 ♀, same location and collector, 19 vi 2015.

Description of female. Head ( Fig. 14d View FIGURE 14 ). Labrum, base of mandibles, anteclypeus and postclypeus shiny black. Genae pale blue, the blue continuing a little inward over the antefrons above the postclypeus, remainder of frons matte black. Dorsal surface of head matte black, apart from two irregular pale blue lines from the edge of the compound eyes to the lateral ocelli, interrupted behind the antennae, and two oblong greenish blue postocular spots. Antennae black, top of first segment and base of second segment pale grey. Compound eyes in life blackish brown dorsally, greenish blue below.

Thorax. Prothorax ( Figs 16d View FIGURE 16 , 17d View FIGURE 17 , 21c View FIGURE 21 ): black with a rounded greenish blue spot laterally on the middle pronotal lobe and lower half of propleuron white. The posterior pronotal lobe ( Fig. 21c View FIGURE 21 ) broad and flat, fan-shaped, lacking lapels. Synthorax ( Figs 19d View FIGURE 19 , 20d View FIGURE 20 ): mesepisternum black, with a distinct blue antehumeral stripe along almost its complete length. Mesepimeron black, mesinfraepisternum black with some white adjacent to coxa. Metepisternum bluish yellow, with a narrow margin along wing base, connected to broad black line over metapleural suture. Metepimeron and metinfraepisternum pale yellow. Legs: coxae and trochanters pale yellow. Femur grey with black lines, remainder, claws and spines dark grey.

Wings. Hyaline, 21 Px in FW, 20 in HW. Pt red, covering 1.5 cells.

Abdomen ( Fig. 28a View FIGURE 28 ). S1 bluish white below with posterior margin and dorsum black; S2 black dorsally and blue below, with apical black ring; S3–7 blackish with some bluish below; S8 blackish with clear cut blue dorsal apical half ring and small blue posteroventral spot; S9 black with clear-cut blue apical dorsal half ring; S10 black ( Fig. 22e View FIGURE 22 ).

Anal appendages ( Fig. 22e View FIGURE 22 ). Cerci black, just over half as long as S10, ovipositor black, extending the length of S10 beyond S10, with dorso-apical pale spot.

Measurements (in mm). HW 34; abdomen incl. appendages 51.

Differential diagnosis. The female of C. galbina is reminiscent of the females of Indocnemis orang (Förster in Laidlaw, 1907) and I. marijanmatoki Phan, 2018 , and the female of C. ambigua Asahina, 1997 , which are all large and have dorsally blue ringed S8–9 and similar synthorax and prothorax pattern. Coeliccia ambigua has more contrasting ventral markings near the nodes of the abdomen, but I. orang and I. marijanmatoki are similarly blackish. Coeliccia ambigua has a posterior pronotal lobe of typical Coeliccia form, with a small rounded central part and small lapels, whereas in C. galbina these lapels are absent and the posterior pronotal lobe is very broadly fan-shaped ( Fig. 15c View FIGURE 15 ). Female I. orang also lacks lapels, but has a simple posterior pronotal lobe, which is not incised laterally, whereas that of I. marijanmatoki is not nearly as wide, but apparently also lacks lapels (Phan 2018). In the female of these two Indocnemis species the pterostigma is warm brown, not red as in C. galbina .
