), this species can be diagnosed by the narrow, subquadrate elytra and the impressed and distinctly punctate discal elytral striae (Fig. 42A). The pronotum is only slightly transverse - MPW/PL = 1.14 - and basally constricted; MPW/BPW = 1.52. The eyes are moderately small, leaving the posterior fifth of the protruded ocular lobe uncovered; ocular ratio = 1.43, ocular lobe ratio 0.82. Standardized body length 3.7 mm. Head with convex frons, frontal grooves linear, convergent anteriorly, with transverse wrinkles radiating onto frons from grooves; anterior and posterior supraorbital setae proximate, separated by 3

Pronotum cordate, lateral margins concavely convergent for short distance anterad projected, obtuse hind angles, the distinct angle filled with a triangularly raised bead; median base sloped upward to meet convex disc, moderately depressed, with ~14 deep punctures each side, the punctures elongate along discal margin; anterior transverse impression broad, shallow, more defined laterally along anterior margin posterad slightly convex anterior callosity, fine longitudinal wrinkles lining impression laterally; front angles slightly protruded, very tightly rounded; lateral marginal depression narrow, edge beaded, depression broader inside front angles but beaded margin as high there as laterally; laterobasal depression a shallow extension of the discal base, smooth unilaterally, irregularly rugose on other side of type specimen. Elytra moderately convex, the sides gently sloped to the lateral marginal depression; discal surface between intervals 1-4 appearing flat each side (single specimen has crumpled elytra), sutural interval raised as a median callous; discal striae 1-5 moderately convex, punctate, the elongate punctures slightly enlarging strial breadth, striae 6-7 smoother, surface undulated along length; striae 1-7 variously shallower basally than on disc or obsolete for short distance posterad elytral basal groove; humeri distinctly angulate, basal groove evenly curved, MEW/HuW = 1.97; eighth interval subcarinate laterad stria 7, upraised above stria from subapical sinuation to apex; lateral elytral setae 7 + 6.

Coloration of head dark rufous, clypeus and labrum rufoflavous; antennomeres 1-3 rufoflavous, 4-11 rufobrunneous; pronotal disc dark rufous to match frons, lateral margin depression narrowly, median base broadly, rufous; elytral disc rufobrunneous with silvery metallic reflection; sutural interval rufous basally, rufoflavous apically, lateral marginal depression narrowly brunneous; femora rufoflavous, tibiae rufoflavous with brunneous cast.
