( Figs. 1 , 5 , 22 )

Mimastra badia Kimoto, 1989: 85 (key), 86 (original description). Mimastra badia: MEDVEDEV (2002) : 256 (synonymized with M. polita Jacoby, 1889 ).

Type locality. ‘ Laos, Vientiane Prov., Ban Van Eue’.

Type material examined. PARATYPES: 2 JJ 1 ♀, ‘ LAOS: / Vientiane Prov. / Ban Van Eue / 30.VIII.1967 [w, p] // Native / Collector / BISHOP [w, p] // PARATYPE [blue label, p] // Mimastra / badia / n. sp. [w, p]’ ( BPBM).

1 ♀, ‘ LAOS: / Vientiane Prov. / Ban Van Eue / 15.II.1967 [w, p] // Native Collector / BISHOP MUSEUM [w, p] // PARATYPE [blue label, p] // Mimastra / badia / n. sp. [w, p]’ ( BPBM) [female not corresponding to M. badia ]; 1 ♀, ‘ LAOS: Vientiane / Prov., Gi Sion / Vill., de Tha Ngone / 2.I.1966 [w, p] // Native Collector / BISHOP MUSEUM [w, p] // PARATYPE [blue label, p] // Mimastra / badia / n. sp. [w, p]’ ( BPBM) [female of Mimastra submetallica ]; 1 ♀, ‘ LAOS: / Sedone Province / Paksong / 16.V.1965 [w, p] // Native Collector / BISHOP [w, p] // PARATYPE [blue label, p] // Mimastra / badia / n. sp. [w, p]’ ( BPBM) [female of Mimastra submetallica ].

Differential diagnosis. Dorsum including apical margin of elytra uniformly yellow. Underside yellow, metathorax and abdomen black. Legs yellow, apices of tibiae gradually darkened, tarsi infuscate. Aedeagus as in Fig. 1 . Spermatheca as in Fig. 5 . Body length according to the original description: 5.30–6.80 mm; body length of examined paratypes: males 5.50–5.90 mm; female 5.75 mm.

Distribution. Laos, Thailand, Vietnam ( KIMOTO 1989).

Comments. According to the original description ( KIMOTO 1989), the type series includes the holotype deposited in BPBM and 153 paratypes deposited in BPBM and the Kitakyushu Museum of Natural History and Human History (Fukuoka, Japan). I had the opportunity to examine six paratypes of M. badia from BPBM. Three paratypes from ‘ Vientiane prov., Ban Van Eue, 30.VIII.1967 ’ that fit the original description and are in my opinion conspecific with the holotype (not examined) refer to true M. badia . Two female paratypes with yellow abdomen (from ‘ Vientiane prov., Gi Sion vill.’ and ‘Sedone prov., Paksong’) undoubtedly belong to M. submetallica . Another paratype (female) from ‘ Laos, Vientiane prov., Ban Van Eue, 15.II.1967 ’ is a female of an unidentified Mimastra species , different from M. badia . This female has a black collar on the base of the head and black margin of the elytral apex. MEDVEDEV (2002) synonymized M. badia with M. polita Jacoby, 1889 . My comparison of the type material of both species revealed differences in the structure of the aedeagus ( Figs. 1 , 11–12 ). Based on the material examined, M. badia is resurrected from the synonymy with M. polita .
