Female: figs 223-225 . Body size: 13 mm.

Black. Bright ferruginous: tip of ventral clypeus, mandibles, scape, legs but coxae. Wings weakly yellowish. p deeply impressed on head and mesosoma, denser and often coalesced on lower frons, ocellar area, posterior vertex, middle disk and anterior lateral area of N 1, outer disk of Es 2. Disk and posterior surface of P completely sculptured with no distinct p but a little area near anteroventral corner of disk; fine wrinkles on its lateral areas. mR and shallow and sparse p (I far larger than their diameter) on Te, deeper p on Ste. cOc complete, even though somehow rough near vertex, with low buttressing ridge along it on temples and genae. Rough wrinkles on postero ventral corner of N 1. Median furrow well defined by lateral ridges crossing the whole P disk. Gradulus present on 3 rd tergum too. 6 th tergum almost completely wrinkled but apical border.

N o t e. It is very close to ( M. erythropoda ) in coloration, but differs in: red scape (dark brown); dark brown flagellum (bicolor, with reddish ventral side); cOc with buttressing ridges on temples and genae (absent); roughly wrinkled lateral N 1 (largely shagreened with only short fine wrinkles); disk and posterior surface of P completely sculptured with no distinct p (with small, shallow p and distinct I throughout); gradulus on 3 rd tergum only (gradulus on both 3 rd and 4 th terga).

Male (Holotype): figs 226-230; body size: 14 mm.

Black. Yellow: the whole clypeus, mandibles, subapical stripe and anteroventral corner on N 1 disk, foreborder of tegulae, the whole X 1 and most of X 2, ventral apex of X 3 ventral femurs, fore tibiae, all tarsi, apical stripe with waving fore edge on 1 st to 6 th Te. Bipunctate area around ocelli and vertex by sparse small p among larger ones. Variabilty in size, 12 to 14 mm.

Epipygium without median notch and completely convex (well evident in back aspect) with a very weak lateral ridge just apically.

Derivatio nominis. From the number (ʌȑȞIJİ = five) of flagellar tyloida.
