Redescription (Holotype, female). Body length 2.6 mm. Body reddish brown, elytra slightly paler, unicolourous; legs and antennae reddish.

Antero-lateral margins of frons simple. Gular rugules of different sizes, anteriorly larger, ordered, contiguous to fused as in Fig. 139 View Figs 133–140. 133 . Clypeal granules minute but distinct. Setation of head vertex fine, appressed, with some longer, more raised setae at base, distinctly coarser and subdecumbent around eyes and ventro-laterally.Antennae rather moderately long; antennomeres III–V nearly 1.8 times, X 1.2 times as long as wide; setation mostly fine, distinctly coarser to scaly and with some long, raised setae on basal two antennomeres.

Pronotum moderately transverse, its lateral margins rather strongly, evenly convex in dorsal view; posterior collar very narrow and inconspicuous. Pronotal horn robust and wide, triangular, its posterior angles distinct in dorsal view ( Fig. 162 View Figs 159–167 ); horn margins armed with 4 lobules on each side, apical lobule simple, widely rounded; horn crest very distinct, strongly raised, rather short, with coarse rugules on margins; submarginal rugules mostly coarse and distinctly spaced; median rugules largely fused and forming irregular sculpture, with several minute granules scattered posteriorly. Setation whitish, slightly yellowish to reddish dorsally, largely scaly and appressed to subdecumbent, finer, much sparser and raised on pronotal horn dorsally; scales on pronotal disc of two sizes, larger scales more raised, subdecumbent and distinctly truncate apically, their surface somewhat glossy; antebasal paired setae absent medially and probably present laterally, difficult to recognize owing to presence of another tactile setae (especially antero-laterally).

Elytra 1.6 times as long as wide; omoplates and postbasal impression absent. Setation scaly, reddish to brownish and whitish, mixed and forming also rather vague darker markings, appressed and evenly ordered; scales nearly linear, rounded to truncate apically, glossy, distinctly spaced (surface visible, Fig. 181 View Figs 177–185 ); scattered tactile setae absent, but humeri with several longer and more raised, stiff setae.

Male characters (Bushmans Beach, SAMA). Sternum VII nearly simple, slightly produced medially. Tergum VIII and aedeagus as in Figs 88–90 View Figs 88–97 .

Variation. Body length (♂ ♀) 2.1–2.8 mm. Pronotal horn with 3–4 lobules on each side, varying in prominence of posterior angles and shape of lobules ( Figs 162, 163 View Figs 159–167 ). Brownish setose markings may be reduced to absent (Levi Creek). The specimens from the southernmost (Levi Creek, Moree) and deep inland localities (Simpson Gap) show more or less distinct differences in the shape of the parameres and the postero-ventral margin of male tergum VIII ( Figs 91–94, 95–97 View Figs 88–97 ).

Differential diagnosis. Mecynotarsus phanophilus   seems to be very close to M. obesus   sp. nov., both in male and external characters, however, it differs by the shorter, more compact horn crest, by the narrower, nearly linear and apically rather truncate body scales (cf. Fig. 181 View Figs 177–185 versus 179) that are partly subdecumbent on the pronotum, by the less prolonged and rounded apex of the parameres, and by the rounded posterior margin of male tergum VIII (not emarginate). Externally, it may also resemble M. bullatus   sp. nov., but differs by the smaller body size, distinct and more or less separate rugules of the crest margins (never fused and forming a strongly raised and evenly shaped, semicircular rim), the somewhat denser setation of the elytra, the somewhat slender antennae (especially the less robust basal antennomere), the absence of scattered tactile setae on the elytra, and mainly by the form of the parameres (cf. Fig. 89 View Figs 88–97 versus 34).

Distribution. Australia: New South Wales (new record), Northern Territory (new record), Queensland ( LEA 1922), South Australia (new record).
