Description. Total length 1.5–1.8 mm. Color light reddish-testaceous throughout. Antennal club slightly longer than funicle; antennomere XI triangular, slightly longer than IX and X combined. Head punctation extremely fine and sparse; eyes separated on frons by about 2.5 times width of a single eye (in frontal view). Pronotal punctation almost nonexistent; posterior margin not bordered; with weak scutellar lobe; hind angles obtuse. Elytron devoid of microsculpture, without distinct punctures, without transverse strigae, with weak but evident diffraction grating; with sutural stria quite weak, extending about 2/3 length of elytron, without a trace of additional striae. Prosternal process (including translucent projection) extending well beyond procoxae; prosternum devoid of setae. Protibia with ctenidium extending about 2/3 length of tibia. Metaventral process (including mesoventral posterior margin) with slight depression, not appearing emarginate. Metaventrite without distinct punctures, densely setose medially; metaventral postcoxal lines smoothly arcuate, enclosing an area about 1/6 length of metaventrite behind coxae. Metatarsomere I slightly shorter than II; metatarsomeres I and II together much longer than remainder of tarsus ( Fig. 21d ).

Tegmen of aedeagus with fused parameres bluntly pointed, without median cleft ( Fig. 21h ). Penis widest at about middle, with smoothly rounded tip ( Fig. 21i ). Spermatheca as illustrated ( Fig. 21j ).

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

Distribution. Known only from North Sulawesi (Sulawesi Utara), Indonesia.

Etymology. Named in honor of the late Ernest S. Lewis (1924–2009) of Chagford, England, for his (mostly unpublished) contributions to the understanding of Phalacridae . The epithet is a noun in the genitive case.
