Description. Female (Holotype). Dorsum largely dark shining castaneous with a slight metallic greenish lustre; ventral surfaces as above except abdominal ventrites slightly paler, more orangish fuscous. Antenna with segments 1–3 and 10–11 orange-fuscous, intermediate segments dark fuscous; legs largely orangefuscous. Body surfaces mostly smooth, lustrous, bright under lights but abdominal ventrites subshagreened with fine sculpture. Dorsal pubescence of moderately long and bristle-like setae sporadically arranged in various directions, ± forming large rosettes; vertex with a central rosette.
Head: frontal surfaces flattened and continuous with interantennal space; frons finely and closely punctulate; vertex similarly punctulate, disc with a distinct median line; eye with maximum diameter about 0.5 x as broad as interantennal space; gena 0.5 x as deep as eye. Antenna slightly exceeding mid-elytron; pedicel about 0.5 x as long as segment 3; intermediate segments slender; apical 5 segments much heavier than preceding. Prothorax about 0.6 x as long as broad, broadest across middle with 2 distinctive teeth marking broadest part; sides otherwise evenly narrowed to apex and base; posterior angle weakly produced; base finely beaded; discal surface uneven, transversely depressed on sides along posterior 2/5; disc closely punctulate. Elytron gradually narrowed to preapex; preapex sinuately narrowed to extremity; inner disc largely confusedly punctate, the punctures small, deep but distinctly larger than pronotal ones and 2– 3 x as large as interspaces; posterior 1/5 with punctures becoming more regular adjacent to suture; humerus slightly swollen; postbasal area with 2 meandering heavy costae, the inner disappearing near suture and the outer reaching preapex. Ventral surfaces: propleuron with small deep punctures, commonly 1 x as large as interspaces; shining interspaces shining; metasternum with shallow small punctures, surface with fine sculpture; ventrite 1 in lateral view evenly and convexly elevated to metasternum; intercoxal piece 0.21 x as broad as basal breadth of segment; remaining ventrites appearning normal. Legs: femora normally slender-incrassate; metatibia nearly straight, dilated at apex. Genitalia: spermatheca with receptacle an elongate and nearly closed u-shape. Measurements: Body length 3.9 mm; body breadth 1.9 mm; head breadth 118 cmm; interantennal space 38 cmm; interocular space 70 cmm, eye 36 cmm, gena 18 cmm; pronotal length 100 cmm; pronotal breadth 158 cmm (across posterior teeth); elytral length 2.9 mm.
Male (Allotype). Similar to holotype, including distinct pronotal teeth laterally; elytral disc more evenly convex and lacking costae. Ventral surfaces: abodominal ventrites essentially on an even, flat plane in lateral view. Genitalia: aedeagal apex as in Fig. 3a. Measurements: Body length 3.25 mm; body breadth 1.65 mm; head breadth 106 cmm; interantennal space 30 cmm; interocular space 58 cmm; eye 36 cmm; gena 16 cmm; pronotal length 90 cmm; pronotal breadth 138 cmm; elytral length 2.5 mm.

Remarks. A larger dark castaneous species differing from all congeners by having a double-toothed prominence on each side of pronotum and by having ± erect, unkempt setae in various large rosette patterns. Both sexes treated. The name commemorates the planet Mars.
