Diagnosis.
As with the two previously described species this will key out to couplet

Wood’s 2007
key. It differs from these and related species by the spatulate, confused interstrial setae on the disc and declivity.

Female.
Total length:
2.3 mm
, maximum width: 1.0 mm, length of elytra: 1.5, total length / width: 2.30, elytra length / total length: 0.65, pronotal length / width: 0.80.
Frons convex; central area from above level of eyes to epistoma smooth, sparsely punctured, peripheral areas faintly strigose. Vestiture of sparse, hair-like setae. Antennae missing from unique
holotype
, presumably like that of related species.
Pronotum with two prominent teeth on the anterior margin, with 10–12 teeth on the anterior slope, vestiture of hair-like setae. Summit prominent, but not elevated, about ½ distance from anterior to posterior margins, without posteriorly directed extensions or carina. Disc smooth, shining; punctures deep, separated by greater than their diameters. Vestiture of disc a mixture of hair-like and scale-like setae.
Discal striae not impressed, interstriae 3× width of striae, smooth, shining. Interstrial vestiture of erect spatulate setae, rounded apically, their length less than interstrial width, mostly uniseriate, near base, becoming confused towards declivity. Strial setae short, hair-like, recumbent.
Declivity evenly convex, rounded; interstrial setae longer than on disc, almost as wide as interstriae, setae definitely confused on interstriae 2 and higher. Strial setae similar to those on disc.
Male.
Unknown.
