M a l e
T y p e m a t e r i a l e x a m i n e d : Holotype: ČR, Nový Jičin, 29.V.1930, Igt. Gregor ["macrellips"20], Id.
E t y m o l o g y : This species is given a name macrellips that often is used on the labels of the Gregor's material.

D i m e n s i o n s : Body length 3.1mm.

H e a d : Narrowly elongated behind eyes, 1.55 times as broad as long, in frontal view 1.25 as broad as high. Ocellar triangle 1.3 times shorter than OOL. POL 4 times longer than Od. Temples look elongated, about twice longer than LO. In frontal view eye twice as high as long, about as long as malar space. Face 1.5 as broad as high, 1.5 times as broad as LD, 4 times higher than clypeus. Maxillary palpi as long as height of face and clypeus combined. Antennae with 20 segments, as long as body length. Scape slightly widened, 1.5 times as long as wide; Is' flagellum segment 3 times as long as wide, the others elongated and apical segments twice as long as wide.

M e s o s o m a : 1.5 times as long as high. Propodeum with a clear transverse carina and obtuse lateral tubercles.

W i n g s : Length of cell R along metacarp 0.7 as long as length of pterostigma. Cell R twice greater than Rm2. 3-SR vein 1.5 times shorter than r, 4 times shorter SRI. 1-CU1 shorter than cu-a.

L e g s : Hind femur 3.5 times as long as broad. Outer and inners spurs of hind tibiae equal in length, as long as 1/2 of 1SI metatarsal segment, 5Ih segment as long as 3rd, a little shorter than 2nd, 1.3 times longer than 4th.

M e t a s o m a : Carapace gradually enlarged posteriorly, 1.7 as long as maximal broad on its 1/3. In lateral view almost parallel-sided, about 1.2 times as high posteriorly as anteriorly. AMA big, bean-formed; 0.7 as broad as carapace, about 0.5 height of carapace.

S c u l p t u r e : Head dense puctate. Face very fine conversely striate. Vertex finelly transversely striate. Temple finely longitudinally striate. Clypeus finely punctate, shining. Mesonotum rugose-punctate and scutellum as well. Sides of mesonotum rugose without clear longitudinal elements. Propodeum rugulose punctate with granulate sculpture, anteriorly with a longitudinal carina ending to transverse carina and looking as two small teeth. Carapace longitudinally rugulose, fine winding undulations ending to its 2/3, apex without longitudinal elements of sculpture.

C o l o u r : Body black. Palpi dark brown. The basal part of antennae, prothorax, carapace and AMA partially dark-brownish. Legs dark, coxae almost black; fore femora brown with lightly apex, tibiae brown-yellowish with lightly basal part, tarsi light-brown; hind femora dark-brown, tibiae brown with lightly basal part, tarsi light-brown. Wings faintly infuscate. Pterostigma and veins brown-yellowish.

D i a g n o s i s : This species by some characters (antennae, head elongate behind eyes, shape of AMA, partially sculptured carapace) is closed to M. temporalis. The comparatively short 3-SR, enlarged carapace and almost parallel-sided carapace (laterally) within M. macrellips sp.n. are sufficient for delimitating these two species.

In the absence within series of M. temporalis of a similar tendency (shortened 3-SR, enlarged to apex carapace) arid, at the same time, the absence of series within M. macrellips sp.n. to discern the variation and, of course, the direction of variation, then it represents an independent species. Ultimately, such feature as carapace's shape (that is obviously different at a simple examination in both species) put these two species apart. Although, as we have seen in case of M. risorius with variable shapes of carapace within big series, then quite possible that it is only a variety of M. temporalis. Even short 3-SR (that is distinctly apparent on specimen M. macrellips sp.n. in comparison to comparatively long 3-SR within M. temporalis) can be just a part of variation (a similar case is described within M.foersteri's series).
