Coeliccia yamasakii Asahina, 1984

( Figures 3 e–f, 4c–d, 6e–f, 7)

Examined specimens. 2 ♂♂, 2 ♀♀, K7, Phu Quoc NP, Kien Giang Prov., 05 iii 2018, To Van Quang leg.

Notes. Coeliccia yamasakii was originally described from Chonburi Province of Thailand based on male specimens ( Asahina 1984) and later was recorded from Phu Quoc Island of Vietnam ( Bui 2007) and southwestern Cambodia ( Kosterin & Holden 2011). We describe the female of C. yamasakii although photos of the female (habitus in nature) were previously provided by Bui (2007: p. 15), Kompier (2017) and Kosterin & Holden (2011: Fig. 4 ).

Description of the female. Head ( Fig. 7 c–d). Labrum black with dark yellowish marking centrally. Mandibles and genae pale blue, this pattern extending to base of antennae at level of distal margin of postclypeus. Anteclypeus pale blue with two black spots on lower margin. Postclypeus entirely black. Top of first and second segments of antennae yellowish, remainder black. Epicranium matte black except for two wavy large yellow stripes each extending eye margin to posterior ocellus, and with a pair of oblong yellowish postocular spots.

Thorax ( Figs 6 e–f, 7d). Prothorax black dorsally, propleuron yellowish ( Fig. 7d ). Posterior margin of the posterior pronotal lobe only slightly extended, erected in lateral view ( Fig. 6 e–f) and with two distinct lapels. Synthorax: black with a long, narrow yellowish antehumeral stripe; mesepimeron entirely black; metepisternum and metepimeron largely yellowish with black stripe along their border. Mesinfraepisternum and metinfraepisternum entirely yellow. Legs ( Fig. 7d ): coxae and trochanters entirely yellowish; femora yellowish with black externally; tibia, spines and claws brownish black.

Wings. Hyaline, 18 px in FW and 19–20 in HW. Pt brown, covering 1.5 underlaying cells.

Abdomen ( Fig. 7e ). S1 largely yellow, black dorsally and at posterior margin; S2–7 black dorsally, ventral margin yellowish with subapical yellow annulus; S8–9 black with an oval yellowish spot laterally, lower margin of S8 yellowish; S10 black.
