 Diagnosis. This species can be distinguished from all other species by the elongate body form (Figs. 128, 129), ferrugineous to bronze color, elongate pronotum, absence of anterior and posterior pronotal margins (Fig. 25), and complete impressed elytral striae (Fig. 128).   
 Description (male). 4.5–6.5 mm long, 2.5–3.5 mm wide. Small, body elongate, moderately convex; broadest in anterior half of elytra; elytra strongly tapered at apex, giving it a teardrop-shaped body form (Figs. 128, 129). Ferrugineous to bronze; antennae, mouthparts and tarsi ferrugineous. Head moderately punctuate dorsally; punctures smaller than a single eye facet; shagreened. Antenna weakly clavate, nearly filiform; antennomeres 7–10 weakly widened apically, forming a loose, elongate club; apical antennomere subcircular; antennomeres 7–10 with stellate sensoria. Mentum with acute median keel, anteriorly raised to a point (Figs. 10, 12). Ventral portion of eye not reaching subgenal sulcus (Fig. 8); postgena without distinct punctures. Dorsal surface of pronotum weakly punctate; appearing smooth, shagreened. Pronotal marginal bead complete laterally; anterior and posterior margin lacking marginal bead; anterior angles of pronotum nearly right, moderately produced and widely rounded apically; lateral edge of pronotum evenly curved to base (rarely weakly sinuate at base); pronotum evenly convex (Fig. 130). Hypomeron without distinct punctures. Prosternal process apically rounded, with distinct marginal grooves opposite coxae joined apically (Fig. 131). Elytral striae deeply impressed, present as rows of small punctures separated by 0.5–1.0 3 diameter with a deeply impressed line through the middle of each puncture row, connecting the row of punctures; elytral interstriae roundly convex, sparsely punctate, shagreened; scutellary striae short, 1–3 punctures long; scutellum triangular, reduced (Figs. 128, 130). Mesoventrite thin antero-posteriorly, U-shaped, shallowly excavate, receiving prosternal process; metaventrite,1/2 antero-postero length of mesocoxa (Fig. 131). Metathoracic wing vestigial. Legs long, slender, lightly punctate; femora reaching beyond edge of elytron; tibiae straight; metatibia with ventral tooth vestigial (Fig. 48). Abdominal depressions on 4th and 5th ventrites reduced to indistinct slits (Fig. 74); intercoxal process of first ventrite apically rounded; ventral surface weakly punctate; shagreened (Fig. 131).   
 Female. Identical to male, except metatibia lacking ventral tooth proximad apex.   
 Biology. This species has been collected by beating vines in moist to wet forest at high elevations.   
 Distribution. This species is endemic to Montserrat and has been collected on Katy Hill, Roache’s Estate south of Soufriere Hills at the Upper Pond, and the Trail to Big River (Fig. 269). A long series was also collected by H. G. Hubbard in ‘‘clearings’’ at 2,000 ft, probably in 1894 (Ivie et al. 2008).   
 Etymology. The species epithet, used as a noun in apposition, is from the Latin word lacrima, which is derived from the Greek word, dáKRUMa, meaning a tear. This species is shaped like a teardrop and is thus named lacrima.
