Description. Total length 2.7–2.9 mm; relatively elongate, nearly parallel-sided at middle one-third; dorsum abruptly flattened, sides of pronotum and (especially) elytra nearly vertical starting at about stria 7; lateral margins slightly explanate, especially posterior portion of elytra. Color testaceous to rufotestaceous throughout; without trace of diffraction grating, dorsal surface devoid of microsculpture. Antenna short, about as long as width of head; antennal club slightly more than half as long as funicle, weakly formed; antennomere XI short, nearly circular. Punctation of head extremely fine and dense; punctation of pronotum slighly coarser but less dense, with interspersed micropunctures; elytral punctation dense, even, slightly coarser than that of pronotum, becoming crescentiform laterally, appearing almost as transverse strigae at some angles; elytron with single engraved (sutural) stria, but with eight additional lightly impressed, punctate striae traceable nearly entire length of elytron. Prosternum somewhat setose medially, with pair of short, stout setae preapically on prosternal process. Mesoventrite punctate nearly throughout. Legs short, femora, tibia, and tarsus of all legs stout; tarsomeres 1–3 of all legs with dense pad of setae; metatarsus only slightly longer than mesotarsus. Protibia with two stout spines at outer apical angle. Metatarsomere I slightly shorter than II, about as long as III.

Tegmen of aedeagus with wide, spatulate dorsal strut; fused parameres with three pairs of lateral setae, proximal pair longest; penis slightly bisinuate at apex, with complex series of sclerites in internal sac. Female genitalia unstudied.

Diagnosis. This species may be recognized by the characters given in the generic diagnosis.

Distribution. Known only from southwestern Australia ( Fig. 44e View FIGURE 44 ).

Etymology. This species is named in honor of Dr. John Lawrence of Gympie, Australia, who first brought to my attention and provided me with all known specimens of this distinctive new genus of Phalacridae . The epithet is a noun in the genitive case.
