DIAGNOSIS: In addition to attributes provided in the generic diagnosis, recognized by the unique carinate lateral margin of the pronotum and somewhat smaller size than in M. grossi (pl. 19); endosoma in M. carinatus large and nearly J-shaped (fig. 58, pl. 19), whereas in M. grossi endosoma smaller and more strongly sigmoid (fig. 59, pl. 19); antennal segment 2 in M. carinatus much shorter than in M. grossi .

DESCRIPTION: MALE: Mean total length 3.25, mean pronotum width 1.18. COLORATION (pl. 19): As in generic description. SURFACE AND VESTITURE (pl. 19): As in generic description. STRUCTURE (pl. 19): Head: Weakly transverse, conforming to anterior margin of pronotum, eyes not bulging; frons rounded and moderately projecting beyond eyes; eye occupying slightly less than twothirds height of head; antenna inserted just above ventral margin of eye, eye not emargin ‐ ate at insertion; antennal segment 2 short (0.44), stout, of uniform diameter, 0.57 times width of head; labium reaching midpoint of mesosternum. Thorax: Pronotum broad along midline and shieldlike, lateral margins carinate, weakly convex, posterior margin moderately excavated; mesoscutum moderately exposed. Hemelytron: Lateral margin rather strongly convex, overall body form broadly ovoid. GENITALIA (fig. 58, pl. 19): Pygophore: Triangular. Endosoma: Large, J-shaped and weakly sigmoid, apical portion from basal curve to apex of endosoma about twice as long as basal curved region; dorsal strap bifid proximad of secondary gonopore forming short narrow spine terminating proximad of gonopore and long thin, minutely serrate, apical spine subtended by short prominent triangular spine; ventral strap terminating as thin spine subapically at level of prominent spine of dorsal strap. Phallotheca: Dorsal margin with short crest basad. Parameres: Left paramere elongate in dorsal view, dorsoposterior margin produced posteriad, slightly elevated above posterior and anterior processes; posterior process with undulating lateral margin, distally long and straight; anterior process small, broad basally, forming sharp apex on anteromedial surface; prom ‐ inent seta on lateral surface of lobe. Right paramere elongate, somewhat fusiform with blunt medial point.

FEMALE (pl. 19): Coloration as in male; differing from male as in generic description; mean total length 3.24, mean pronotum width 1.21.

ETYMOLOGY: From the Latin, carina, “keel,” in reference to the carinate lateral margin of the pronotum.

HOST: Recorded from Eremophila scoparia (Scrophulariaceae) .

DISTRIBUTION (map 16): Known from southeastern South Australia and the Kalgoorlie region of Western Australia.
