Measurements male / female. Head length: 1.14 / 1.314; head width: 2.21 / 2.42; pronotum length: 2.06 / 2.28; pronotum width: 3.39 / 3.75; tegmen length: 9.5 / 10.38; tegmen width: 2.875 / 3.1; total length: 11.575 / 12.68 (in mm). Diagnosis. Tegmina brownish to black with two narrow transverse bands in orange shades, posterior band never fragmented into spots; paramere with a dorsal margin rounded and developed and with a finger-like apex. Redescription. Head black, vertex subretangular with a slightly marked median carina, ocelli brownish, closer to each other than to eyes, separated by about one and a half diameter from each other; tylus quadrangular, black, basal third with slightly marked carina, becoming indistinct towards the apex (Fig. 7 A – E); antenna brownish, pedicel sparsely setose; basal body of flagellum subcylindrical with a single and short arista shorter than the pedicel length. Postclypeus black, inflated, with convex profile, longitudinal carina present, lateral grooves slightly marked (Fig. 7 F, G); rostrum with second segment reddish and third segment brownish, reaching the base of mesocoxae. Pronotum brownish, hexagonal, with muscular insertions slightly apparent, median carina slightly marked; anterior and anterolateral margin straight; posterolateral with slight sinuosity and posterior margin medially grooved, humeral angles acute; scutellum black, with slight central concavity and slightly marked horizontal grooves. Tegmina (Fig. 7 A – E) brownish, narrow, with two narrow transverse bands orange: one between basal and medium third and another between medium and apical third; veins M and Cu 1 united at base, veins A 1 and A 2 distincts, apical reticulation developed, prominent venation. Hindwings hyaline, with brownish venation, Cu 1 thickened at the base, hamuli with four spines. Legs reddish, metathoracic femur with a small apical spine; tibia with two lateral spines, basal one smaller than the ones located at apical crown, which has 12–13 spines arranged in two rows; basitarsus with three rows of spines covered by long setae; subungueal process present. — MALE: Genitalia: Pygofer (Fig. 7 H) with one finger-like processes between anal tube and subgenital plate; subgenital plate (Fig. 7 H, I) narrowing towards apex, which is rounded, dorsal margin with rounded elevation covered with small tooth-like spines; basal process of subgenital plate short and rounded followed by an excavation. Paramere (Fig. 7 J) subretangular, with a finger-like apex, dorsal margin rounded and developed, and a subapical hook-like spine bearing small denticles in the inferior margin, directed outwards and forward. Aedeagus (Fig. 7 K – M) subcylindrical, narrowing towards apex, with a pair of straight dorsal processes, shorter than half length of shaft and inserted medially. — FEMALE: Morphology similar to that of the male, but slightly larger in relation to total body length. First valvula of ovipositor long (Fig. 7 N, O), with acute apex, basal process rounded and undeveloped, directed downwards; second valvula (Fig. 7 P) long with rounded apex and dorsal margin covered by teeth in apical third; third valvula short and wide, covered apical and ventrally by long setae. Remarks. M. (I.) rubicunda shows a high variation in the body color, ranging from black to light brown and the transverse bands on the tegmina can vary in shades of red, orange, yellow, and whitish (Fig. 7 A – E). M. (I.) rubicunda and M. (I.) indentata are synonyms because there are small and not significant morphological variations between these species. Furthermore, Fennah (1953), while describing Delassor, mentions M. (I.) indentata as a subspecies of Delassor rubicundus, showing that the similarity between these two species was observed by the author. The wing pattern is also similar to that of M. (I.) integra; however, the bands are narrower and more widely spaced. Additionally, there are several differences in the male genitalia: the subgenital plate has a rounded apex, and the paramere has a digitiform-shaped apex in M. (I.) rubicunda, which is not observed in M. (I.) integra. Distribution.
