Female: figs 169-171 . Body size = 12 mm.

Female. Body size = 11 mm. Black. Ferruginous metasoma but petiole, declivitous 1 st tergal surface and 1 st sternum which are brown.

cOc complete. Hyc does not touch ventral cOc so that PoG is well expressed with distinct median suture. Lateral N 1: fig.29 . Lateral P with many (more than 40) very fine subhorizontal wrinkles. Scopa; fig. 171 . Gradulus present on 3 rd tergum, absent in 4 th one. 6 th tergum mostly wrinkled.

Male: figs 172-176 . Body size = 11mm.

Black. Brown: clypeal disk; flagellum; semitransparent tegula; most of legs; apical 6 th and 7 th metameri. Yellow: small median spot on clypeus which has dark ventral edge, most of mandible; very subtle subapical spot on Tsa; ventral X 1, spot on X 2, markings on fore legs; apical narrow stripe on 1 st tergum; apical stripe with strongly indented fore edge on both sides, appearing three spotted, on 2 nd to 4 th Te; two lateral spot on 5 th tergum, 2 nd to 4 th sterna. Wings hyaline.

Mid flagellomeri with a ratio L / LA about 2.4. Ventral edge of median clypeal lamina almost straight. N 1 disk with bluntly angled fore border and no tooth on its anteroventral border; its ratio LApos / Lmed about 3.3. Fore and back edges of Em 3 like a stitch. Acutely laminated ventral apical hind femur. Tergal surface with sparse (I larger than their diameter) differently sized p but not clearly bipunctate. Apical 1 st sternal surface with p. 7 th tergum with short epipygium and rounded lateral edge just along its apical lobes; median notch as large as lateral lobe.

N o t e. Female looks like M. abdominalis , but it shows lesser size, different N 1, subhorizontal surface of P, scopa and especially a well developed PoG.

Derivatio nominis. From the typical locality.
