The types of the species described by Émile Blanchard in d’Orbigny’s (1835-1847) Voyage dans l’Amérique méridionale

The type specimens of the true bugs (Hemiptera, Heteroptera) described by Émile Blanchard in the extensive monographic work Voyage dans l’Amérique méridionale by Alcide d’Orbigny (1835-1847) were studied. All are deposited in the Muséum national d’Histoire naturelle in Paris (MNHN). From the 19 described species we found the type specimens of 17, and also one non-type specimen from one additional species recorded in this work. We selected lectotypes for 13 nominal species, and established two new combinations and synonymies: Arilus spiniceps Blanchard, 1842 is transferred into the genus Sindala Stål, 1861, with the new combination Sindala spiniceps (Blanchard, 1842) n. comb. and synonymized with Sindata granuligera (Stål, 1860) n. syn.; Paryphes miniaceus Blanchard, 1842 is transferred into the genus Laminiceps Costa, 1863 with the new combination Laminiceps miniaceus (Blanchard, 1842) n. comb. and synonymized with Laminiceps conjunctus Brailovsky, 1992 n. syn. Also, dorsal, ventral, and lateral habitus photographs, and photographs of labels of all 17 types are given.
