( Figs 22 View FIGURES 1–28 , 137–138 View FIGURES 137–146 )
Diagnosis. FEMALE. The following combination of characters is diagnostic: pronotum broader than propodeum; mesosoma uniform orange; scutellar scale rounded posteriorly, ~2 punctures wide; legs partly orange; metasoma entirely black; T2 sculpture coarse; T2 disc spots moderate and separated by approximate spot diameter; T2 and T3 bands interrupted medially by black setae; and T6 without pygidium. Body length 3.5–6.5 mm. MALE. Unknown.
Description. FEMALE. Body length 4.4 mm. Coloration. Head black, except frons ventrally, antennal tubercle, mandible, clypeus, scape, and pedicel orange-brown. Mesosoma and legs orange-brown, femoral and tibial apices darkened. Metasoma black, except S1 orange, and T1 and S2 partly red-brown. Body setae generally sparse and silvery, except frons and mesosomal dorsum with sub-erect mostly red-brown setae; T2 disc, T4, and T5 setae dense black; and vertex, T2 disc lateral spots, T2 apical band, T3 entirely, and T6 basal tuft with dense pale golden setae; T2 lateral spot diameter 1.1 × distance between spots; T2 apical band and T3 band narrowly interrupted medially with black setae. Head. Width behind eye subequal to mesosoma width. Frons, vertex, and gena punctures confluent. Mandible apex narrow bidentate. Clypeus apically bidentate, teeth connected by weak transverse lamella; basomedial portion with weak flat tubercle. Antennal scrobe with arcuate dorsal carina nearly continuous to mandible base. Antennal tubercle with weak punctures and sparse setae. Genal carina obscure, forming small tooth at hypostomal carina and extending posteriorly to occipital carina. F1 2.0 × pedicel length, F2 1.4 × pedicel length. Mesosoma. Length subequal to width. Dorsum of mesosoma with coarse confluent punctures; wavy carina separating dorsal and lateral faces of pronotum and mesonotum. Side of mesosoma with dense micropunctures and short setae. Mesopleural lamella an obscure interrupted carina. Humeral carina weak, complete. Ratio of width of humeral angle, anterior spiracle, narrowest point of mesonotum, propodeal spiracle, and midpoint of propodeum 48:55:44:48:51. Scutellar scale sub-truncate posteriorly, ~2 punctures wide, surrounded by scattered tubercles. Posterior propodeal face reticulate with many interspaces obliterated leaving tubercles. Lateral and posterior propodeal faces separated by row of teeth. Metatibio-tarsal ratio 42:18:13:9:8:8. Metasoma. T1 anterior face with dense punctures, posterior with confluent punctures. T2 disc with separated ovate pits, interspaces densely micropunctate and setose; with obscure transverse arcuate depression in apical half. T3–5 and S3–5 with small dense punctures. S1 with longitudinal lamella, shallow emarginate medially. S2 with sparse punctures, interspaces smooth. T2 felt line 0.3 × T2 total length. T6 convex without any trace of pygidium. S6 posterior margin rounded.

Etymology. We are proud to name this species after Donald G. Manley for his many contributions to velvet ant taxonomy and systematics.
Remarks. In Chen’s (1957) key, this species terminates at couplet 3 of the Smicromyrme key, because the clypeus is entire and the T2 disc spots are well-defined and subcircular. In Mickel’s (1935) key, it keys to Petersenidia psecas ( Mickel, 1935) , which is known only from Borneo, has a defined pygidium, and lacks an apical T2 band.
