Fig. 1A-G Type material. Holotype . Thailand • ♀; Don Phao, Mae Wang, Pa Huay Kho, Chiang Mai, Thailand; 18.692°N , 98.807°E ; iv.1997; Saowapa Sonthichai; collected in an edge of mixed deciduous lowland forest using Malaise trap. Will be deposited in Queen Sirikit Botanic Garden Entomology Collection (Chiang Mai, Thailand, QSBG). Diagnosis. Adult body size smaller than that of O. junyani sp. nov. Face with stronger punctures (Fig. 1E ). Malar space 1.2 x longer than basal width of mandible (Fig. 1E ). Mesoscutum with stronger and larger punctures (Fig. 1C ). Mesopleuron with stronger punctures (Fig. 1C ). Fore femur apically pale. Apical fourth of fore wing infuscate (Fig. 1B ). 3r of hind wing present basally (Fig. 1B ). The ratio of propodeum (median length to width) = 0.7 (Fig. 1D ). Propodeal areola narrow and spindle-shaped (Fig. 1D ). Inner space of Y-shaped suture entirely smooth (Fig. 1D ). Y-shaped suture entirely crenulate (Fig. 1D ). Description. Body 5.5 mm. Head . Antenna with 38 segments. Face width 1.2 x longer than its height (1.02:0.83). Width of anterior ocellus 0.8 x longer than POL (0.15:0.18). Median width of eye about 0.8 x longer than the median width of gena in lateral view (0.29:0.36). Clypeus 1.9 x longer than its height (0.67:0.35). Malar space 1.2 x longer than basal width of mandible (0.24:0.20). Mesosoma . Scutellar sulcus with five carinae. Pronotum ventrally carinate, posteriorly crenulate. Mesopleuron dorsally rugulose, medially smooth, ventrally punctate (evenly punctured entirely). Metapleuron crenulate medially and rugulose anteriorly and posteriorly. Propodeum 0.7 x longer than its median width (0.67:0.96), strongly rugulose; median areola 2.1 x longer than its maximum width (0.53:0.25) and spindle-shaped. Legs . Basal spur on fore tibia 0.9 x longer than length of basitarsus (not measured using images). Basal spur on mid tibia 0.9 x longer than length of basitarsus (0.59:0.64). Basal spur on the hind tibia 0.7 x longer than length of basitarsus (0.62:0.88). Wings . Fore wing 5.5 mm; second submarginal cell trapezoid, 2.8 x longer than height (1.05:0.38); pterostigma about 2.8 x longer than wide medially (1.08:0.38). Metasoma . T1 1.2 x longer than its posterior width (0.79:0.64), separated with lateral tergum by suture anteriorly and by color posteriorly; Y-shaped suture entirely crenulate; inner space of Y-shaped suture entirely smooth. T2 0.3 x longer than its posterior width (0.33:1.34), with curved posterior margin, 0.7 x longer than T3 (0.33:0.50). T3 0.3 x longer than its posterior width (0.50:1.48). Protruded ovipositor sheath 0.5 x longer than length of hind basitarsus (0.47:0.88), with long setae at apical half. Color . Body mostly black or dark brown except for the following, which are pale ivory or white: area between lateral clypeus and dorsal mandible; apical and penultimate maxillary palpomeres; glossa; apical fore femur; entire fore tibia, fore tarsus, and mid tarsus; basal mid tibia and hind tibia; tibial spurs; T1 laterally; ovipositor. Wings hyaline basally and infuscate at apical fourth. Pterostigma mostly dark except for base and apex. Body color is similar to a pattern of O. dvaravati sp. nov. but possessing brighter metasoma and several whitish leg parts. Male. Unknown. Biology. Unknown. Distribution. Ophiclypeus chiangmaiensis sp. nov. is known from Don Pao, Mae Wang, Chiang Mai, Thailand (Fig. 4 ). Etymology. This species is named after the collecting site, "Chiang Mai Province". Notes. The first author attempted to obtain molecular data from a specimen of O. chiangmaiensis sp. nov. collected in 1997 but failed, and there was no attempt to acquire molecular data from a specimen of O. dvaravati sp. nov. collected in 2016. In the future research, molecular analyses based on newly collected specimens and portions of existing museum specimens will be helpful in placing Ophiclypeus gen. nov. into a broader phylogenetic context with other cardiochilines.
