Holotype, male (Fig. 26a). Length 2.78 mm. Color of antennae light ferruginous, legs dark ferruginous; remainder black. Body subovate, in dorsal aspect with weak constriction between pronotum and elytron; profile dorsally convex. Rostrum with median ridge and pair of submedian ridges, intervening furrows each with row of coarse punctures and sparse row of mesad directed setae; epistome with transverse subangulate ridge. Pronotum dorsally longitudinally rugose, with median costa; furrows containing sparse rows of mesad directed slender scales; laterally coarsely punctate. Elytra with striae distinct, marked by rows of punctures; each containing small white bristle, partly abraded; laterally punctures larger; intervals flat, subglabrous. Femora with simple anteroventral ridge. Metafemur subapically with stridulatory patch. Abdominal ventrite 5 at middle with shallow, densely punctate impression, with suberect scales. Penis (Fig. 26b) with sides of body slightly converging; apex subangulate, with median, subtriangular extension; dorsally behind orifice with distinct median carina, projecting convex in profile; transfer apparatus with pair of elongate, crescent-shaped sclerites; apodemes 2.8 × as long as body; ductus ejaculatorius without bulbus. Intraspecific variation. Length 2.40–2.95 mm. Color of elytra with more or less distinct bronze lustre. Female rostrum in apical half dorsally subglabrous, with submedian row of minute punctures; epistome simple. Elytra with striae as in holotype, or punctures of striae subbasally corrugate (two specimens from Tetebatu), or striae markedly impressed and intervals costate (two specimens from Senaru). Female abdominal ventrite 5 flat.

This epithet is based on the Latin participle disruptus (broken apart) and refers to its phylogeography which appears to reflect the division of the species in two populations.
