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.
