Description Male. Head: Antenna brown-orange; basoflagellomere 1.5 times as long as wide, 1.5 times longer than pedicel, concave dorsally, apex acute; arista: second, third and basal part of fourth flagellomeres pale, fourth flagellomere brown and thickened basally and dark brown apically, 1.5 times longer than basoflagellomere, covered with dense pollinosity. Face and frons black, covered with long whitish-yellow pile and silver to gray pollinosity. Oral margin shiny black, well protruded. Vertical triangle isosceles, 2.2 times longer than eye contiguity, shiny black, covered with long whitish-yellow pile, except black ones in the ocellar triangle. Ocellar triangle isosceles. Eye contiguity about 9–11 ommatidia long. Eye pile as long as pedicel, whitish in the lower part, light brown in the upper third. Occiput with whitish-yellow pile, along the eye margin with dense white pollinosity and posteriorly with metallic blue-greenish or bronze luster.
Thorax Scutum and scutellum black with bronze-green luster, covered with dense, erect yellow-orange pile, as long as, or slightly longer than basoflagellomere; pile on scutum arranged in indistinct longitudinal vittae (two narrow submedial and two wider sublateral are darker). Pleura covered with gray pollinosity, and the following parts with long yellow pile: most of anepisternum (except the ventral part of anterior anepisternum and anteroventral part of posterior anepisternum), anteroventral corner of proepimeron above procoxa, anteroventral and posterodorsal part of katepisternum, anepimeron, metasternum; katatergum covered with dense, erect, short, light-brown pile. Wing hyaline, with dense, brown microtrichia, with the exception of a small bare area above and below vena spuria, in the proximal 1/3 of br cell. Calypter pale yellow. Halter with light brown pedicel and and capitulum; capitulum darker on lower part. Femora brown-black, except paler apex and posterior margin of apical triangular lamina; tibiae brown-black, with paler basal 1/3–1/4 and apex; tarsi orange-yellow, except apical two tarsomeres brown-black dorsally and joints between tarsomeres black. Metatrochanter with long thorn-like processus, curved backwards ( Fig. 4d View Fig : p). Metafemur thickened (2.6 times longer than wide) and with slightly convex dorsal margin ( Fig. 3d View Fig ). Metatibia simple, without apical spur(s), but with angular apex ( Fig. 3d View Fig ). Pilosity of legs predominantly yellow-orange, with the exception of short black pile dorsally and antero-basally on pro- and mesofemora, and apically on metafemur; few black pile also present dorsally on tarsi; additionaly medium long black pile intermingled ventrally in apical 1/3 of mesofemur. Pilosity long on pro- and mesofemora posteriorly; antero-dorsally and ventrally on metafemur (not longer than half width of metafemur).
Abdomen Black with bronze reflections, slightly tapering, as long as mesonotum. Tergite 2 with a pair of lateral orange spots. Tergites and sternites shiny, without pollinosity; predominantly covered with yellow-orange pile, except on tergites 2–4 with black pile postero-medially.
Male genitalia ( Fig. 11 View Fig ) Anterior surstyle lobe bends inward ( Fig. 11a View Fig : al), in lateral view of rhomboid shape ( Fig. 11b View Fig : al); thorn-like extension on the medium part of surstyle less protruded and containing two small spines within ( Fig. 11a View Fig : t and 11b: mp); posterior surstyle lobe large and rounded ( Fig. 11b View Fig : pl); cercus clubbed ( Fig. 11b View Fig : ce). Hypandrium with a thorn on thecal ridge ( Fig. 11c View Fig : th). Lateral sclerite of aedeagus slender, with pointed apex ( Fig. 11c View Fig : s).
Length Medium-sized species, with body measuring 12 mm and wing 7 mm in length.
Female Unknown.
Diagnosis Male: metatrochanter with strong, apically curved thorn-like processus ( Fig. 4d View Fig : p); male genitalia: similar to M. kozufensis sp. nova and M. olympius sp. nova from which it differs due to a large and rounded posterior surstyle lobe ( Fig. 11b View Fig : pl) (shorter, almost rectangular in M. kozufensis sp. nova and M. olympius sp. nova) and less protruded median part of surstyle ( Fig. 11b View Fig : mp). Molecular data: 3′-end mtCOI gene (MN264345); 5′-end mtCOI gene (MN295608) and 28S rRNA gene (MN264391).
Material examined Type material: Holotype, male, Montenegro: Orjen Mountain , Crkvice, N: 42.561111, E: 18.630833, 28.viii.2011, A. Vujić ( FSUNS).
Distribution. Mountain Orjen in Montenegro.
Etymology. The word orjensis is derived from the name of Dinaric Mediterranean mountain Orjen, located near the Adriatic coast ( Montenegro), where the species was discovered.
