28a. Promecidia ninnii (Magretti, 1892)

(Figs 25, 145–146)

Mutilla ninnii Magretti, 1892: 211, ♀

Promecidia ninnii: Lelej 2005: 81, ♀; Lelej et al. 2016: 116, ♀.

Diagnosis. FEMALE. This species can be recognized by the following combination of characters: the posterolateral propodeal margin is multi-dentate; the legs are almost entirely orange-brown; the metasoma is black; T2 has a distinct apical band of whitish setae; the white setal band of T3 is not interrupted with black setae; and T4–5 have the setae mostly black. Body length 5.5–7 mm. MALE. To be described in an upcoming paper, likely P. birmanica (Dalla Torre, 1897) .

Material examined (8 ♀). CAMBODIA, Siem Reap, Preah Kahn Temple, Malaise trap, 8–16.VI.2005, I. Var (1♀ RBINS) . THAILAND: Chiang Mai: Omkoi District, Dry dipterocarp forest, 17°50′49.9″N 98°22′33.0″, 950–1010 m alt., 6.XI.2016, R. Mizuno (1♀ EUM); Road 1013, km 34, 1.VI.1999, C.W. and L.B. O’Brien (1♀ CASC); Kanchanaburi, Thong Pha Phum, Vimarndin farm stay, 14.655 o N 98.521 o E, 200 m, 17–20.V.2018, MKT (2♀ CSCA); Krabi: 19.5 km NW Krabi, 8.201 o N 98.751 o E, 10 m, 1.IV.2017, MKT (1♀ CSCA); Nakhon Si Thammarat, 4.4 km N Hin Tok, Mountainside rubber farm, 8.303 o N 99.849 o E, 7.IV.2017, MKT (1♀ CSCA) ; Phetchaburi, Kaeng Krachan, Baan Maka Nature Lodge, 12.840 o N 99.590 o E, 140 m: 22–23.V.2018, MKT (1♀ 1♂ in copula CSCA).

Distribution. Cambodia * (Siem Reap), Myanmar, Thailand (Chiang Mai, Kanchanaburi, Krabi, Nakhon Si Thammarat, Phetchaburi), Vietnam (Dong Nai).

Remarks. Based on overlapping distribution, Lelej et al. (2016) suggested that P. birmanica (Dalla Torre, 1897) might be the male of this species. A mating pair of P. ninnii was collected in Phetchaburi. The male keys out to P. birmanica, but careful examination with type material will be needed before proposing this synonymy.
