Occipital carina dorsally distinctly bell-shaped, fading out at distance shorter than basal width of mandible from the hypostomal carina. Temple and gena moderately wide, gena somewhat swollen and projected (as in Fig. 261 ).

THORAX: Pronotum glabrate, shiny, impunctate, ventrally with strong wrinkles; epomia strong, distinct only after diverging from pronotal collar, moderately long, ending near dorsal margin of pronotum, after diverging from pronotal collar distinctly curved. Mesoscutum moderately and uniformly convex, ovoid, 1.37 × as long as wide, glabrate, shiny, anteriorly scarcely punctate, posteriorly almost impunctate; notaulus reaching about 0.7 of mesoscutum length, moderately impressed, surface over notaulus with weak and short transverse wrinkles; scutoscutellar groove moderately deep, without wrinkles. Subalar ridge weakly projected; epicnemial carina reaching about 0.7 of distance to subalar ridge, irregular; sternaulus moderately strong, wider on posterior apex, strongly sinuous, with vestigial vertical wrinkles; scrobe moderately deep; mesopleural suture with strong longitudinal wrinkles along entire length. Mesosternum medially with short transverse wrinkles; median portion of posterior transverse carina of the mesothoracic venter short and almost indistinct, straight. Transverse sulcus at base of propodeum moderately wide, about 0.54 × as long as anterior area of propodeum, impunctate; metapleuron moderately punctate, without transverse wrinkles, dorsally sparsely pilose, ventrally moderately pilose; juxtacoxal carina represented by very short ridges. Fore tibia distinctly swollen. Mesal lobe of t4 with a distinct cluster of stout bristles. Hind coxa with moderately strong punctures separated by more than their own diameter.

PROPODEUM: 1.1 × as long as wide, shiny, sparsely pilose; anterior area almost impunctate; spiracle elongate, SWL 5.33; anterior transverse carina medially slightly arched forwards. Propodeal wrinkles strong, moderately widely spaced, mostly incomplete and overlapped, with some disperse complete wrinkles, mostly slightly curved or somewhat sinuous; posterior transverse carina entirely absent.

WINGS: Fore wing vein 1-Rs+M distinctly sinuous, with bulla placed on basal 0.4; crossvein 1m-cu more or less uniformly curved, limit between 1m-cu and 1-Rs+M more or less traceable; vein 1M+Rs anteriorly irregular, posteriorly curved; fore wing crossvein 1 cu-a basad of 1M+Rs by 0.84 of its own length; vein 2Cua 0.35 × as long as crossvein 2cu-a; bulla of crossvein 2m-cu placed mostly on posterior half; cell 1+2Rs small, APH 0.53, subquadratic, distinctly wider than high, AWH 1.27; crossvein 3r-m partially spectral, 2r-m and 3r-m subparallel, about same length; vein 3-M distinctly shorter than 2-M; 4-Rs distinctly sinuous; 4-M spectral, straight. Hind wing vein 1-M forming distinctly obtuse angle with vein Cua; vein 2-Rs tubular, apically spectral, reaching wing margin; HW1C 1.35; vein Cub distinctly convex on posterior half, forming distinctly obtuse angle with vein Cua (basally curved); vein 2-1A reaching 0.89 of distance to posterior wing margin.

METASOMA: First tergite short, about 0.34 × as long as T2–8, somewhat depressed, ventrolaterally angled, dorsally glabrate, laterally moderately pilose; T1LW 3.21; T1WW 1.71; spiracle on 0.49 of its length, distinctly prominent; median depression elongate, distinct; lateral and median posterior depressions absent; ventrolateral carina absent. T2LW 1.27; T2WW 1.87; thyridium longer than wide, without small circular depression just behind it; T2–8 densely punctate and minutely and weakly coriarious, moderately and uniformly pilose except glabrate postero-dorsal area in T2–3. OST 1.49; ovipositor moderately stout, straight, basally cylindric, apically slightly depressed; dorsal valve with four moderately strong ridges; ventral valve apex with 9 teeth, 1st, 2nd and 3th widely spaced; surface anterior to first tooth rugulose.

Color. Head black, mesosoma black and pale yellow, metasoma orange. Head: black; clypeus, basal 0.4 of mandible, mouthparts, supra-clypeal area and complete orbital band, pale yellow (233,215,149); f6–8 entirely white, f5 partially white, f9 dorsally white, f10–12 with dorsal white marks. Mesosoma: black; pronotal collar, dorsal margin of pronotum, propleuron, subcircular spot on mesoscutum, scutellar carina, scutellum, axillar carinae, postscutellum, tegula, subalar ridge, central mark on mesopleuron, most of mesosternum, dorsal division of metapleuron, metapleuron except anterior and posterior borders and arc-shaped mark on propodeum, pale yellow; fore and mid legs pale yellow, somewhat lighter towards apex; all coxae with large black mark at mesal face; fore and mid coxae, trochanters and femora dorsally with longitudinal black stripe; fore tibiae with ventral blackish stripe; fore and mid t5 blackish; mid t3–4 fuscous; hind coxa with posterior longitudinal black stripe; hind first trochanter with basal black mark, dorsally extending on basal 0.5; second trochanter and femur dark orange; hind tibia basally bright yellow, orange on apical 0.4; hind tarsus bright yellow, apically whitish. Metasoma: bright orange (198,087,046); T1 pale yellow, with black mark at median 0.4, laterally extending to basal 0.3; S1 pale yellow; T2 with small anterior and lateral blackish marks.

Male. Unknown.

Variation. General tone of yellow varying from almost white to buff.

Comments. Very similar to M. euryoikos sp. nov., from which it can be differentiated by having mid and hind coxae yellow and black (vs. mostly orange); posterior area of propodeum with one arc-shaped mark (vs. with two ovoid longitudinal yellow marks); postscutellum yellow (vs. black); flagellum flattened and widened at subapical 0.3 (vs. with uniform width); apical area of clypeus medially straigh (vs. concave); epomia and wrinkles on pronotum strong (vs. weak); propodeal wrinkles moderately widely spaced (vs. closely spaced); and ovipositor ventral valve with nine teeth (vs. six). It is also similar to M. lordos sp. nov., which differs from M. apiopharkis by having posterior area of propodeum with two sublateral, subtriangular marks ( Fig. 184 ); mesosternum black (vs. mostly yellow); metapleuron mostly black (vs. almost entirely yellow); and propodeum densely punctate (vs. scarcely punctate), with anterior transverse carina medially distinctly arched backwards (vs. slightly arched forwards).

Biology. Unknown.

Etymology. From the Greek words apios, meaning “far” and pharkis, meaning “wrinkle”; in reference to the widely spaced propodeal wrinkles.

Material examined. 2 ♀ Holotype ♀ from ECUADOR, Pichincha, Tinalandia , 800 m, II.1983, Malaise trap, M. Sharkey ( AEIC). Pinned. Tip of right antenna broken and regaled in the specimen; otherwise in good shape.

Paratype: 1 ♀, same data as holotype .

Distribution. Recorded only from the type locality, in Ecuador ( Fig. 299 ).
