Thorax Pronotum broad, more than 2.5 X as wide as long and distinctly longer than head, lateral margins convergent, distinctly spinose, armed with nineteen, almost all long except few very short spines, humeral angles spinose, length of pronotum 4.1 mm, width 10.1 mm; corium with six short but distinct teeth on each side; scutellum distinctly longer than its width at base, apex sub-rounded, length of scutellum 7.5 mm, width 5.3 mm; distance, apex scutellum-apex abdomen including membrane 4.7 mm; evaporatoria of metathoracic scent gland ( Fig. 2A) well defined with outer margin sinuate, ostiolar peritreme large, thick with anterior margin concave, anterolateral lobe of evaporating area spine-like, broad at base; membrane of hemelytra almost equal to last segment of abdomen both in male and female.

Abdomen Connexiva well exposed at repose with joints acutely produced and lateral margins armed with about twenty six long acute spines, abdomen with deep sulcation on ventral side, accommodating long labium.

Male genitalia Pygophore with dorso posterior margin with shallow, broad cavity without median projection ( Fig. 2B), ventro posterior margin sinuate with shallow, cup shaped cavity with distinct U-shaped median excavation ( Fig. 2C), lateral lobes of pygophore distinctly projecting upward with prominent demarcation, apex concave with both apices acutely produced ( Figs. 2 B-C); paramere Lshaped, comprising three parts, foot, stem and blade, stem short, narrow and without inner thumb like process, blade elongate, narrow, almost rectangular with apex slightly thinly lobed, outer upper margin almost straight ( Fig. 2D); inflated aedeagus with highly sclerotized theca, pair of thecal, highly sclerotized, thin, long, finger-like ventrolateral appendages, pair of dorsal membranous conjunctival appendages thick, slightly tapering upward with a much narrower and very small apical lobe, pair of sclerotized medially fused penial lobes, distinctly longer than dorsal conjunctival appendages, a tubelike vesica, shorter than penial lobes ( Figs. 2 E-F).

Female genitalia Female terminalia damaged in allotype, spermathecal bulb small, proximally round with three processes, two small, finger – like and almost of equal size, third large, thick and forked at apex ( Fig. 2G).

Comparative note M. izmirensis is closely related to M. spinosula in having, middle of hind tibiae reddish brown, head relatively broad, as broad as long with eight upwardly directed spines on each lateral margin, paraclypei wider apart, leaving clypeus free. However it is different from M. spinosula in having, entire body jet black except few ocharceous spots, corium black, lateral margins of pronotum with nineteen spines ( Fig. 1), labium relatively long, reaching 4th abdominal sternite, peritreme long and thick ( Fig. 2A). The male pygophore that has dorso posterior margin with shallow, broad cavity and without dorso-median projection ( Fig. 2B) which is also a diagnostic character of the genus, ventro posterior margin sinuate with shallow cup-shaped cavity and with distinct u-shaped excavation ( Fig. 2C), lateral lobes of pygophore distinctly, narrowly produced with clear demarcation, distinctly lobed with apex concave and apices distinctly acute ( Figs. 2B, C); paramere L-shaped with stem short, relatively narrow, almost as narrow as blade and without thumb process, blade narrow rectangular and with outer upper margin almost straight without small round projection, apex thinly lobed. M. spinosula is dark brown, corium with yellowish spots, pronotum with sixteen spines, labium short extending to 2 nd abdominal sternite, peritreme short and slim, The male pygophore of spinosula that has dorso posterior margin with deep cavity and distinct dorso-median projection, ventro posterior margin with quite deep and narrow V- shaped cavity, lateral lobes projecting upward without distinct demarcation, with apex convex and a little bifid, paramere F-shaped, stem with prominent inner thick thumb- like process and blade relatively broad, tapering acutely towards apex and outer upper margin with a little sub-round, hump-like projection near apex and other characters as noted in description and key.
