Description.
Body length 6-8, sub-oblong, slightly convex, almost uniformly orange brown to black, sometimes with fine red or brown stripes or red brown areas (
Figs 56–58
). Head gradually sloping anteriorly, in profile tylus distinctly curved and joined to frons without a notch (

,

). Labium reaching mid or posterior coxae. Pronotum
Megacoelum
-like. Pilosity of metatibia erect, elongate, longer than width of tibia. Tibial spines dark. Scutellum almost flat, slightly tumid. Dorsal pilosity relatively long, erect, sparse, black or dark brown, particularly obvious on scutellum and hemelytra. Hemelytra slightly reflective, frequently translucent, almost smooth, with double punctation, one very reduced, dense, narrow and shallow, second shallow but wider. Veins raised. Spiculum of phallus developed, apical,

-like (
M. beckeri
) or subapical, rounded, with several dorsal teeth (
M. irbilanum
). ACH, comb and gonoporal process absent. Secondary gonopore complete, devoid of associated sclerite, hairs or pilose plate. Female genitalia unknown.

Discussion.
The west Palearctic species of
Megacoelum
sensu
lato
with erect, elongate metatibial pilosity, longer than tibial width, were classified by
Linnavuori (1974b)
in his group two. We suggest they constitute a separate genus.
