Diagnosis.

Female. Body length 12-20 mm. Front with deep punctures in front of anterior ocellus; lateral carina of propodeum extended beyond spiracle; forewing yellowish and hyaline, with first submarginal cell almost entirely covered with short setae and with a large black spot subapically; legs ferruginous; antenna black; mandible often red-brown; T1-T3 with narrow yellow bands apically; apical fringes on T1-T4 reddish-golden; erect vestiture and tomentum reddish-golden, except black on two last metasomal segments (Fig. 5A ).

Male. Body length 10-13 mm. Antenna and legs wholly black; metasoma with faint blue reflections; clypeus, except for large black spot medially, base of mandible, lower part of inner eye orbit, scrobe, elongate mark on gena, scapula, callosity, tiny mark on mesoscutum posterolaterally, small spot on tegula anteriorly, narrow band on scutellum anteriorly, large median spot on metanotum, anterior side of fore coxa, apical mark on fore and hind femora beneath, narrow stripes above and below on mid-femur, outer surfaces of fore and mid-tibiae and outer surface of first fore tarsi yellow; apical yellow bands on T1-T4, covering less than one-half of their length (Fig. 5B ); S2-S4 with narrow apical yellow bands, that on S4, broadly interrupted medially; erect vestiture pale white, except black on two last metasomal segments and some black setae on T5 apically; wings hyaline, slightly infumated at apex; forewing without dark mark subapically; base of volsella with sparse setae, distance between bases of these setae more than their own diameter (Fig. 5C ).

Distribution.

Vietnam (new record): Ha Noi, Hoa Binh, Nam Dinh, Quang Ninh, Thai Binh (Fig. 8F ). Elsewhere: Bhutan, China, India, Indonesia, Malaysia, Myanmar, Nepal, Taiwan, Thailand ( Betrem 1928; Gupta and Jonathan 2003; Girish Kumar and Pham Ph 2015; Liu et al. 2021a; Taylor and Barthélémy 2021).

Phalerimeris phalerata is widely distributed in the Oriental region and ranges from Sri Lanka, India and Nepal, eastwards to Southeast Asia and also into China and Taiwan. Three subspecies have been recorded P. phalerata phalerata (de Saussure), P. p. turneri (Betrem, 1928) and P. p. bankanensis (Betrem, 1928). Osten (2005) did not recognise the last subspecies. In females, these three subspecies are distinguished, based on apical fringes on the metasomal terga and the yellow bands on T1 and T2. In P. p. phalerata , the apical fringes on T1-T4 are reddish-golden, the apical fringe on T5 and setae on T6 are black and the yellow bands on T1 and T2 are narrow and continuous in the middle area. In P. p. turneri , the apical fringes on T1-T5 and setae on T6 are reddish-golden and the yellow bands on T1 and T2 are moderately broad and continuous in the middle area. In P. p. bankanensis , the apical fringes on T1-T5 and setae on T6 are reddish-golden and the yellow bands on T1 and T2 are rather narrow and interrupted in the middle. The males of all three subspecies are very similar (de Saussure 1858; Betrem 1928; Gupta and Jonathan 2003).

In some female specimens of P. phalerata phalerata from North Vietnam, the apical yellow bands on T1 and T2 are narrow, about one-third the length of T1 and one-fifth that of T2 and continuous in the middle area. The apical yellow band on T3 is also narrow, but interrupted in the middle. The apical fringe on T5 includes both median black and lateral yellow setae and setae on T6 are entirely black. Therefore, the population of this species in northern Vietnam shows variation suggesting that P. p. turneri should be synonymised with P. p. phalerata .
