(Figs. 14–15)
Diagnosis. This species is characterized by moderate punctuation of hemelytra, dark cuneal apex and shiny, practically bare scutellum.
Description. Body elongate, 2.5x as long as wide. General coloration uniform reddish-brown, apex of cuneus dark. Head bare; corium, cuneus and clavus furnish with golden yellow adpressed setae, pronotum and scutellum scattered short setae. Hemelytra with moderately punctate corium and clavus, moderately pubescent with reclining golden-yellow short setae arising from articulate punctures; cuneus semi-transparence, inpunctate (Figs. 14, 15). Head moderately transverse, 2.36x as wide as long, distinctly wider than anterior margin of pronotum. Vertex 1.64x narrower than dorsal width of eye; eyes globular; combined antennal length of 3rd and 4 t h segments 1.1x longer than 2nd, 2nd segment 3.36x longer than 1st; 4th segment 1.33x longer than 3rd. 4th antennal segment sometimes subdivided into 2 parts; 2nd and 3rd rostral segments equal size in width and length, 2nd segment twice as longer as 1st. 3rd segment 0.91x longer than 4rd. Pronotum trapezoidal in shape, moderately transversal, 1.82x as wide as long; calli weakly developed, intercallian pit weakly expressed; ratio length posterior/anterior margin 2.23x wider than median length; posterior margin weakly convex. Visible portion of mesoscutum narrowly exposed, 4.0x shorter than scutellum length. Claval commissura rather long, ratio length claval commissure/mesoscutum+scutellum 1.25. Cuneus 4.8x shorter in length than length of corium and twice as long as wide; large cell of hemelytral membrane very long, 4.0x as long as wide. Hind tibia 3.64x longer than tarsus; 1st tarsal segment of hind leg very short; 2nd segment 2.77x longer than 1st.
Dimensions. Length of body 2.74, width 1.1; length of head 0.25, width 0.63, dorsal width of eye 0.23, width of vertex 0.14; antennal segments I:II:III:IV= 0.25:0.84:0.39:0.52; rostral segments I:II:III:IV= 0.18:0.36:0:36:0:33; length of pronotum 0.52, width 0.43 (ant.) and 0.95 (post.); length of mesoscutum 0.1; length of scutellum 0.40; claval commissure 0.5; hind femur–invisibly; length of tibia 1.24; length of tarsus 0.34 (I+II = 0.09+0.25).
Etymology. From intergerivus (lat.) = placed between.
Specimens Examined. Holotype, ♂, in Baltic amber (coll. C. Gröhn Nr. 2291) light yellowish and moderatesized piece of amber (29 x 18 mm) of irregular shape. The holotype is deposited in the collection of GPIMH.
Remarks. M. intergerivus shares in such features as ratio width/length pronotum (1,72–1.82) with M. punctatus, M. grabenhorsti, M. variabilis, and M. punctatodiffusus, narrow open part of mesoscutum in M. punctatus, M. variabilis. M. groehni and M. akingbohungbei, and also ratio length claval commissure/ mesoscutum+scutellum (1.2–1.27) in most species (except M. akingbohungbei). M. variabilis has also a very long large cell in hemelytral membrane (3.8–4.0 x as long as wide).
