Here we describe two new species of H. (Harmostes) from Argentina: H. (H.) bilobatus sp. n. and H. (H.) rubrum sp. n. Illustrations of the diagnostic characters and a key to the Argentinean species of the subgenus Harmostes are presented
Considered by many to have been the greatest heteropterist of his time, if not all time. Carl Stål was born in Stockholm, Sweden, 21 March 1833 and died at Frösundavik, near Stockholm, 13 June 1878, at the young age of 45, making his many accomplishments all the more remarkable. He studied medicine at Uppsala University (1853–1857) and earned his Ph.D. in entomology at the University of Jena in 1859, after which he became assistant to Carl Henrik Boheman at the Swedish Museum of Natural History. In 1867 he was appointed professor and head of Zoology. Although noted primarily for his work on Hemiptera, he also published Coleoptera and Orthoptera. He is known for his succinct descriptions of new taxa and broad understanding of higher-group relationships, especially within the Pentatomomorph. His most important works include Contributions to the Rio Janeiro Hemiptera fauna (1860–1862), Hemiptera Africana, (1865–1866), Hemiptera Fabriciana (1868), and Enumeratio Hemipterorum (1870–1876). An obituary was prepared by Reuter (1878) and a list of publications was given by Spangberg (1879). His collection is in the Swedish Museum of Natural History.
