Diagnosis
These robust-bodied species (e.g. Fig. 5D) are geographically restricted to Queensland, Australia, and have been recently revised by Baehr (2003)[1]. The pronotum of species in this subgenus is broad, with obtuse or obtusely rounded hind angles. Each elytron bears a single dorsal elytral seta just before midlength (Fig. 5D). The prosternum is medially depressed both between and anterad the procoxal cavities, a condition shared with most member species of Eucyclothorax, although punctures are not present in the depression. The elytral striae are reduced; striae 1–3 to 1–4 shallow to evanescent, striae 4– or 5–7 obsolete. Striae 1, 7, or both may be present apically on the elytra, but striae 4–6 are consistently absent there. The elytra are broadly convex, with interval 8 not, or only slightly upraised (M.lewisensis) relative to the general curvature of the elytral surface. The suture between abdominal ventrites 1 and 2 is nearly straight, with the second ventrite hardly depressed relative to the first. Body size is small for the genus; standardized body length 2.6–3.7 mm.
The male aedeagal median lobe internal sac bears a flagellum (Liebherr 2018[2], fig. 4E), and the ventral paramere is elongate-conchoid in shape, broadly to narrowly subtriangular with ventral setae present (Liebherr 2018[2], fig. 5B; Baehr 2003[1], fig. 1). The female bursa copulatrix is relatively short (Liebherr 2018[2], fig. 6D). The spermathecal duct joins the bursa copulatrix-common oviduct juncture.
Member species
Baehr (2003)[1] recognized four species, three of them represented by two subspecies each, for a total of seven specific and subspecific forms. The subspecies described below is added to the inventory of M.lewisensis, resulting in three subspecies; M.lewisensis, M.lewisensisuncinatus, plus the newly described subspecies.
