(Figs 31, 59, 75). Habitus: (Fig. 31). Size: [See also Table 3] Medium to large-size for the genus; ABL = 2.089–3.071 mm, SBL = 2.590–3.131 mm, TW (total width) 1.491–1.815 mm, LP = 0.545–0.642 mm, WP = 0.762–0.888 mm, LE = 1.721–2.036 mm. Color: See diagnosis above. Luster: See diagnosis above. Head (Fig. 31): as in description for genus above. Prothorax. Pronotum (Fig. 31) moderately broad, as wide as head across eyes (WP/WH, both sexes: 1.025), longer than head (LP/LH, mean both sexes: 1.471), wider than long (W/L, mean both sexes: 1.380); markedly cordiform and explanate, lateral margin beaded with seta at anterior third; apical margin straight, base markedly constricted with medial lobe at base; anterior angle feebly produced, hind angle markedly prominent and setose; median line moderately defined, apical transverse impression punctate, punctures coarse and infuscated; surface smooth throughout. Pterothorax. Normal for genus, see description for genus above. Elytra slightly convex; at apical third twice as wide as head across eyes (WH/TW, mean both sexes: 0.492) and pronotum (WP/TW, mean both sexes: 0.504). Elytral interneurs evident as short discontinuous rows of fine punctures; punctures with a fuscous halo at basal and apical proximal quadrant of elytron. Hind wings fully developed. Legs. Overall, normal for genus, see description for genus above. Abdominal sterna. Overall, normal for genus, see description for genus above. Male genitalia (Fig. 59, see Fig. 61 for attribute labels). Median lobe with phallobase short about a fifth the length of shaft, basal opening small, oriented parallel to shaft. Shaft broad, slightly curved ventrally, dorsally sclerotized except for short ostium; in ventral aspect tapered toward rather narrowly rounded apex, in lateral aspect, a broadly rounded apex. Left paramere very large and broad, right small and triangular, apex of left paramere lobate much longer than right paramere about half the length of shaft (measured in left lateral aspect). Endophallus with 10 small medial spines and one large distal spine. Female genitalia. (Fig. 75A and B) Ovipositor with broad laterotergite (lt) and two narrow gonocoxites (gc 1, gc 2); gonocoxite 1 apico-laterally not setose; gonocoxite 2 shallowly falcate, base (b) medium-size much broader than narrow blade (bl) which is elongate, with two dorsal ensiform setae (des), ventral ensiform seta absent, ensiform setae moderately short and robust; without ventral preapical nematiform setae. Reproductive tract proximally with moderately short, broad bursa copulatrix (bc), continuous at its distal end with common oviduct (co) and long robust bipartite spermatheca (sp) distal to broad short villous canal (vc), one lobe slightly narrowed distally; spermathecal gland not found in dissection; spermathecal gland duct (sgd) robust, heavily sclerotized, attached to oviduct at base of its broadened portion. Defense gland (Fig. 75C) with an annulated sausage-shaped accessory gland (cc) and large reservoir (gldr) distal to a long efferent duct (ed).

Distribution ( 英語 )

由Zookeys提供
(Fig. 77). This species has been found at only two locations on second-order white-water streams of the Río Negro drainage system. But that does not at all indicate its real distribution: as has been pointed out above, very small beetles are inadequately sampled, especially in the Neotropics.
