Aglymbus bimaculatus Resende & Vanin, 1991: 124 View in CoL ( Brazil: São Paulo Province: Salesópolis: Guaratuba).

Copelatus bimaculatus View in CoL : Balke et al. 2008: 6357.

Material examined: Brazil: 1♂ 1♀, Nova Friburga , Macaé de Cima, 1200 m, viii.1997, (LHCM) ; 2♀♀, Florianopolis , Santo Amaro da Imperatriz, 300 m, x.2004 (ZSMG) . 7♂♂ 5♀♀, same locality, but: in Nidularium innocentii , 15.ii.2005, Zillikens leg. (NMPC, ZSMG) .

Diagnosis: Habitus drop-shaped, more strongly attenuated posteriorly than anteriorly, broadest at 1/3 of elytral length, slightly convex. Body black, clypeus, margins of pronotum and scutellar shield somewhat reddish translucent, appendages testaceous; elytra completely black in specimens from Nova Friburgo ( Fig. 1B View Figure 1 ), but with small oval basal orange spot between striae 4–8 in specimens from St. Amaro ( Fig. 1A View Figure 1 ). Dorsal surface submatt due to well impressed reticulation and presence of fine longitudinal striolae. Head moderately broad, c. 0.57 × width of pronotum, trapezoidal. Antennae with antennomeres rather broad, thus of stouter appearance. Pronotum transverse, broadest at posterior angles; sides strongly and evenly curved, lateral beading distinct except for anterior corners. Elytral striation consisting of 11 superficially impressed discal + a submarginal stria: odd striae, especially striae 5, 7, 9 often incomplete and badly perceptible due to striolation, in some specimens almost absent. Protibia modified, slightly angled near base, distinctly broadened anteriorly, club shaped. Pro- and mesotarsomeres 1–3 distinctly broadened, ventrally with adhesive setae. Natatorial setae present only on dorsal side of metatarsomeres. Median lobe of aedeagus in lateral aspect ʻCʼ- shaped, apex obtusely pointed; in ventral aspect median lobe evenly attenuating to straight, pointed apex ( Fig. 2A–B View Figure 2 ). Parameres broad, ʻDʼ -shaped. Female somewhat smaller than male: TL ♂♂: 6.1–6.4 mm; TL ♀♀: 5.9–6.3 mm. Distribution : The species is distributed in the Atlantic forests, along the coast from Rio de Janeiro to Santa Catarina provinces, south-eastern Brazil ( Fig. 3 View Figure 3 ).
