Material examined
Holotype: ♀, Malaysia, Selangor, Bukit Kutu, 31.I.1930 (BMNH).
Other material
New to Thailand, Lampang Province, Ngao District, Tham Pha Thai NP., 20. XII.2001, S. Hasin leg., (1♀, THNHM); Loei Province, Phu Ruea District, Waranya Resort 17.460 –101.355, 25–26.III.2019, K. Williams, S. Puttasok, K. Thoawan, R. Malee and N. Thaochan leg., (4♀ CSCA); 19.I.1999, W. Jaitrong leg. (1♀ THNHM); Nakhon Ratchasima Province, Wang Nam Khiao District, 09.V.2001, W. Jaitrong and T. Jeentong leg. (1♀, THNHM).
Diagnosis
Female. This species can be separated from other Thai species by having the posterior propodeal surface with uniformly dense small punctures. The following combination of characters are also useful for diagnosis: genal carina short with weak anterior tooth; mesopleural lamella longer than flagellar width, apically rounded; lateral margins of mesosomal dorsum margined with wavy multidentate carina; dorsoposterior propodeal row with median tooth distinct, larger than lateral teeth; T3–5 with brown or black appressed setae and interspersed sparse erect blackish and white to yellowish setae. Body length 5.0–6.2 mm.
Male. Unknown.
Variation
The head and metasoma cuticle colors vary from reddish-brown to black. The appressed metasomal setae vary from brown to black. The cuticle beneath the whitish setal markings of T1 and T2 vary from mostly brown or black to entirely bright whitish-yellow. The size and number of apparent teeth along the dorso-lateral pronotal and mesonotal margins vary. The height of the spines on the dorsoposterior propodeal row varies and the number of spines varies from three to five on each side. The leg color varies from entirely pale orange-brown to mostly dark brown.
Male. Unknown.
Distribution
Malaysia (Selangor); Thailand (Loei, Lampang, Nakhon Ratchasima).
Remarks
This species is newly recorded from Thailand. In the key to Thai females from Williams et al. (2019)[1], B. selangorensis terminates at couplet 4. It can be differentiated from B. lamellata and the other species by having T3 without a distinct band or mesal patch of whitish setae; rather, T3 has sparse interspersed blackish and pale yellow or whitish setae. Unlike the other Thai species, the posterior propodeal surface has uniformly dense small punctures; the other Thai species have the posterior propodeal surface widely areolate, becoming smooth ventrally.
