Plastron: covering genae, sides of prosternum, meso- and metaventrite, inner face of coxae, femora, epipleura and sides of all ventrites. Head: surface microreticulated and rugose, with disperse golden setae. Fronto-clypeal suture straight; clypeus broad, surface as that of head. Labrum subrectangular, lateral angles with long golden setae; surface smooth; anterior margin smooth and shiny. Antennae with 11 antennomeres, apical segment longest. Thorax. Pronotum: wider than long (length: 0.75 mm; width: 0.97 mm) (Fig. 1 e), with oblique and lateral impression at 3 / 5 of pronotum; anterior margin arcuate; lateral margins subparallel, with anterolateral angles acute and long; posterolateral angles blunt; base trisinuate. Surface punctured, space between punctures shiny and smooth; disc punctured, punctures deep and larger than facet of eyes, separated by 1 – 2 times their diameter; surface between sublateral carinae and lateral margin with punctures separated by ½ time their diameter. Sublateral carinae present, extending from apical margin to base, hardly perceptible at base. Hypomeron microreticulated and rugose. Prosternum wider than diameter of procoxa; lateral carinae on basal half; prosternal process subquadrangular, almost as wide as long; apex acute. Mesoventrite with groove for reception of prosternal process. Metaventrite with median longitudinal line extending from base to anterior 2 / 3; surface microreticulated and punctured; punctures larger than facet of eyes, separated by 1 ½ times their diameter; disc with basal third depressed; lateral carinae complete. Legs: elongated; pro- and mesotibiae with lateral cleaning fringe on apical 2 / 3, metatibia with lateral and lateroventral cleaning fringes on apical 2 / 3. Length: forelegs 1.95 mm, middle legs 2.05 mm, hind legs 2.15 mm. Tarsi 5 - segmented, tarsomeres with golden setae, fifth tarsomere longest; tarsal claws long and slender, not modified. Elytra: more than twice as long as pronotum (length: 1.80 mm; greatest width: 1.30 mm); eight punctuate striae formed by punctures larger than facets of eyes, separated by 1 – 1 ½ times their diameter; intervals convex, surface punctured, punctures small separated by 2 – 3 times their diameter, with disperse golden setae; eighth interval carinated; elytral apex moderately protruded. Scutellum subtriangular, almost as wide as long, surface punctured, punctures small, separated by 2 – 3 times their diameter. Abdomen: ventrites convex; surface of all ventrites punctured, punctures like those on metaventrite; disc of ventrite I with complete lateral carinae; surface of ventrite V punctured, punctures separated by their diameter; lateral margin produced as prominent tooth; apex rounded, and margin with long golden setae. Male genitalia: aedeagus (Figs 6 a – b) long and moderately broad. Penis elongate, subtriangular tapering towards apex; apex slightly folded forward (in dorsal and lateral view); fibula and corona present; basolateral apophyses short. Parameres subtriangular, shorter than penis, apices acute. Phallobase asymmetrical, longer than penis, open. Female: externally similar to male except for: 1) small punctures of metaventrite and all ventrites separated by 2 – 3 times their diameter; 2) surface of posterior half of ventrite V with large, deep and contiguous punctures. Female genitalia: as in Fig. 6 c.	en	Manzo, Veronica, Archangelsky, Miguel (2015): Austrelmis Brown (Coleoptera: Byrrhoidea: Elmidae) from Argentina: five new species.
