Eurysternus cyanescens Balthasar, 1939

Eurysternus cyanescens Balthasar, 1939c: 112 .

Three paralectotypes are deposited in NMPC (ex coll. V. Balthasar):

PARALECTOTYPE (J): ‘PARA- / LECTO- / TYPE [p, rounded label, blue margin] // R. de JANEIRO / Petropolis / F. Ohaus S. [p] // Senckenberg / Museum [p] // Mus. Nat. Pragae / Inv. [p] 26345 [hw, orange label] // WORLD / SCARAB. / DATABASE / WSD0002550 [p] // TYPUS [p, red label] // cyanescens m. [hw, green label] // Eurysternus / cyanescens / n.sp. [hw] / Dr. V. Balthasar det. [p] // Eurysternus cyanescens Balth. / PARALECTOTYPE [hw] / det. L. Jessop 1984 [p] // Eurysternus J / cyanescens / Balthasar, 1939 / vid. F. Génier, 1999 [p]’.

PARALECTOTYPE (♀): ‘PARA- / LECTO- / TYPE [p, rounded label, blue margin] // Brasilia / Beske [hw] // Coll. V. Schönfeldt [p] // Mus. Nat. Pragae / Inv. [p] 26346 [hw, orange label] // WORLD / SCARAB. / DATABASE / WSD0002549 [p] // TYPUS [p, red label] // Eurysternus / cyanescens / n.sp. [hw] / Dr. V. Balthasar det.

PARALECTOTYPE (unsexed specimen): ‘Espirito Sto. / Timbuby / L. Ohaus S. [p] // Senckenberg / museum [p] // Eurysternus / cyanescens / n. sp. Balth. [hw] / paratypus [p, orange label] // Eurysternus cyanescens / Balthasar, 1939 / Paralectotypus / det. A. Bezděk & J. Hájek, 2011 [p, red label]’.

Current status. Valid species.

Remark. BALTHASAR (1939c) described this species from an unknown number of specimens. JESSOP (1985) designated a lectotype and two paralectotypes from the syntype series deposited in Forschungsinstitut und Naturmuseum Senckenberg, Frankfurt am Main, Germany and in NMPC. Because there is no doubt about the authenticity of the specimen from ‘Espirito Sto.’ housed in NMPC, we have labelled it as an additional paralectotype.
