03CB8782FFE9DA0EAD19FA735D62FC29.taxon	description	Karl Hermann Konrad Burmeister Karl Hermann Konrad Burmeister (1807 – 1892) was a German naturalist, zoologist, entomologist, herpetologist, botanist and geologist. He was nationalized Argentinean and developed most of his career in that country. In 1850, Burmeister traveled to Brazil, visiting Rio de Janeiro and Minas Gerais states. In the latter, he went to Lagoa Santa spending a season in company of the Danish naturalist and father of Brazilian paleontology and archeology Peter Wilhelm Lund (1801 – 1880). From 1862 to 1892, Burmeister was director of the Argentinean Museum of Natural Sciences, currently known as Museo Argentino de Ciencias Naturales (MACN). He died in Buenos Aires in 1892, at the age of 85. Burmeister’s Centris bees Burmeister described numerous species of flora and fauna from Argentina, four of them being bees of the genus Centris. Three of these species were described based on series of specimens of both sexes collected mainly in Mendoza and Buenos Aires. Although Burmeister did not indicate the name of the collector of those specimens, it is very likely that they were collected by him during his many trips into the interior of the country. Some specimens of the primary series bear labels of holotype, paratype or allotype. However, they were labeled as such after the description of the species and not by Burmeister, since the handwriting is different, and mainly because the concept of paratype and allotype was not established in Burmeister’s time. All type specimens are housed in the MACN.	en	Vivallo, Felipe (2023): The primary types of some species of Centris bees described by European entomologists in the 18 and 20 centuries (Hymenoptera: Apidae).

Peter Cameron Peter Cameron (1847 ‒ 1912) was a very enthusiastic English amateur entomologist and specialist of Hymenoptera. He was a very prolific, and by some considered chaotic, descriptor of species (Morley 1913). His collection is currently housed at NHMUK; his type specimens are also deposited in this collection, as well as at OUMNH. Cameron died in New Mills, England, aged 65.	en	Vivallo, Felipe (2023): The primary types of some species of Centris bees described by European entomologists in the 18 and 20 centuries (Hymenoptera: Apidae).

03CB8782FFEFDA08AD1BF9A25CDEFC4D.taxon	discussion	Cameron’s Centris bee Cameron described only one species of Centris under the name Paracentris fulvohirta Cameron, 1903. The description was based on an undetermined number of males, collected by the English mountaineer, explorer and illustrator Edward Whymper (1840 ‒ 1911). In 1880, Whymper organized an expedition to Ecuador, designed primarily to collect data for the study of altitude sickness and the effect of reduced pressure on the human body (Chisholm 1911). The results of his journey were published in 1892, in a volume entitled “ Travels amongst the Great Andes of the Equator ” (Bonney 1892). During his travel, Whymper made a collection of amphibians and reptiles that he handed over to the Belgian-British zoologist George Albert Boulenger (1858 ‒ 1937) at the British Museum (Boulenger 1882). He also made a very large collection of insects that were housed in the same institution and later studied by Cameron.	en	Vivallo, Felipe (2023): The primary types of some species of Centris bees described by European entomologists in the 18 and 20 centuries (Hymenoptera: Apidae).

03CB8782FFEEDA0BAD1BFB9C5A2DFED4.taxon	discussion	Johann Ludwig Christ Johann Ludwig Christ (1739 ‒ 1813) was a German naturalist, gardener and pastor. Despite being a specialist in Hymenoptera, he also became interested in fruit growing, agriculture and beekeeping while he was a pastor, first in Wetterau and later in Kronberg, Germany (Wilhelm 1957). Christ died in his country of origin, aged 74. Christ’s Centris bee Christ only contributed to the knowledge of Centris describing a variety of C. flavifrons (Fabricius, 1775) from Brazil. Currently, it is considered a junior synonym of that species.	en	Vivallo, Felipe (2023): The primary types of some species of Centris bees described by European entomologists in the 18 and 20 centuries (Hymenoptera: Apidae).

He studied mathematics and natural sciences at the Universität Innsbruck, where he was later hired as professor of zoology (Clément 1928). He studied actively the taxonomy of Hymenoptera, where he published several classic works on specific groups as well as the first catalogues of the order. Dalla Torre died in Innsbruck, aged 77. Dalla Torre’s Centris bee Dalla Torre did not describe any species of Centris, but instead proposed a new name for C. thoracica Smith, 1874, a junior homonym of a species previously described by Lepeletier (1841).

Wilhelm Ferdinand Erichson Wilhelm Ferdinand Erichson (1809 ‒ 1848) was a German doctor and entomologist. He worked actively in different areas of zoology, mainly with beetles, which led him to be appointed curator of the Coleoptera collection of the ZMB (Klug 1850). Erichson died very young, only 39 years old. Erichson’s Centris bee Erichson described several new species of insects, but only two in Centris. When he proposed them, Hemisia Klug, 1807 was considered the valid name of the genus, so he placed his species in it. Later, the genus name was updated to Centris.	en	Vivallo, Felipe (2023): The primary types of some species of Centris bees described by European entomologists in the 18 and 20 centuries (Hymenoptera: Apidae).

Félix Édouard Guérin-Méneville Félix Édouard Guérin-Méneville (1799 ‒ 1874) was a French entomologist, famous for his work “ Iconographie du Règne Animal de G. Cuvier ”, a complement to the work published by the French zoologists Georges Cuvier (1769 ‒ 1832) and Pierre André Latreille (1762 ‒ 1833). Guérin-Méneville founded several magazines of zoology and he was an active member of the Société Entomologique de France. He passed away in Paris, aged 74. Guérin-Méneville’s Centris bee Guérin-Méneville described a variety in the genus Anthophora Latreille, 1803 that actually belongs to Centris. Unfortunately, his contribution was unsuccessful, since the variety he proposed corresponds to a species previously described by Lepeletier in 1841.	en	Vivallo, Felipe (2023): The primary types of some species of Centris bees described by European entomologists in the 18 and 20 centuries (Hymenoptera: Apidae).

03CB8782FFE2DA04AEBCFBA25AA1F844.taxon	description	Anders Christian Jensen-Haarup Anders Christian Jensen-Haarup (1863 – 1934) was a Danish entomologist specialized in Hymenoptera. In 1904, he traveled to Argentina on an insect collecting expedition and spent most of his time in the province of Mendoza. In 1906, he returned to Argentina accompanied by his compatriot, colleague and friend Peter Jörgensen (1870 – 1937). Both naturalists made extensive collections of insects, which they had to sell to cover travel costs or send to specialists for identification (Rasmussen 2007). The specimens of his collection that were not sold or retained by some of their colleagues are currently housed at NHMD. Jensen-Haarup died in Denmark, aged 71. Jensen-Haarup’s Centris bee During his stay in Mendoza, Jensen-Haarup collected some specimens including a new species of Centris that he dedicated to Laureano Lyngbye, his host in the city. Although he did not indicate the date of collection, the specimens were probably collected during his second visit to Argentina.	en	Vivallo, Felipe (2023): The primary types of some species of Centris bees described by European entomologists in the 18 and 20 centuries (Hymenoptera: Apidae).

He taught medicine and entomology at the Universität zu Berlin (currently the Humboldt-Universität zu Berlin) where he also worked as curator of the insect collection (Gerstaecker 1856). He died in Berlin, aged 80. Klug’s Centris bees In 1810, Klug proposed Ptilotopus as a new genus, including in it a single species that he described simultaneously. The species is currently considered valid, but the genus was later downgraded and included as a subgenus of Centris. A couple of years before that publication, Klug (1808) published an article on sexual dimorphism in Hymenoptera, citing some examples in several genera of wasps, ants and bees. Among his comments on species of Centris, he cited “ byssina ”, a species of Hemisia that had previously been named by the German entomologist and zoologist Johann Karl Wilhelm Illiger (1775 – 1813) but that he never formally described. Klug provided some morphological features that allow the identification of this species and the sex of the specimens he studied, resulting in its formal description. The species remained unnoticed during all these years, until a visit to the ZMB where I studied the specimens described by Klug, which had previously been recognized as such by another entomologist. The researcher designated one of the specimens as lectotype, but unfortunately, the nomenclatural act was never published. To formalize this action and avoid future taxonomic problems, this designation is published here, acknowledging the previous work carried out by him.	en	Vivallo, Felipe (2023): The primary types of some species of Centris bees described by European entomologists in the 18 and 20 centuries (Hymenoptera: Apidae).

At least part of the type series is housed at ZMB. The lectotype is here designated bearing the following data label (Fig. 3): [green label with black lower margin] Bah.

However, in this case the priority principle applies (ICZN 1999: article 23.9.1). This allows for prevailing usage of names when the “ senior synonym has not been used as a valid name after 1899 ” (condition 23.9.1.1) and the junior synonym has been used “ in at least 25 works, published by at least 10 authors in the immediately preceding 50 years and encompassing a span of not less than 10 years ” (condition 23.9.1.2). Under this circumstance, both conditions are met because the name ‘ byssina ’ was cited only once by Illiger (1906) as “ Megilla byssina ” (nom. nud.) and then it was completely forgotten, while C. trigonoides is by far one of the most cited Centridine bees (Vivallo 2019 a). Considering this, and according to the article 23.9, C. trigonoides must be considered the valid name of the species (nomen protectum), and C. byssina one of its junior synonyms (nomen oblitum).	en	Vivallo, Felipe (2023): The primary types of some species of Centris bees described by European entomologists in the 18 and 20 centuries (Hymenoptera: Apidae).

Type data This species was proposed based on at least two males collected at an undetermined locality. Moure & Seabra (1960) found two of those specimens in the Spinola collection at MSNT, designating one of them as lectotype, but without providing additional information about its data labels. Unfortunately, the primary type of this species was not available during the preparation of this research. Type locality Unknown. Guillaume-Antoine Olivier Guillaume-Antoine Olivier was a French naturalist and entomologist. He was a very active collector and made a lot of expeditions, he was a very close friend of the Danish naturalist Johan Christian Fabricius, who in 1804 described the genus Centris. Olivier died in France, aged 58. Olivier’s Centris bee Olivier proposed several new species of bees, but only one in Centris. The identity of this species was misunderstood, and it was only fixed recently by Vivallo (2016).	en	Vivallo, Felipe (2023): The primary types of some species of Centris bees described by European entomologists in the 18 and 20 centuries (Hymenoptera: Apidae).

He worked as professor of zoology at the Faculty of Sciences of the University of Bordeaux, France, and was honorary member of the Société entomologique de France (Anonymous 1916). During his professional career, he focused on the study of solitary and social bees. Pérez passed away in France, aged 80. Pérez’s Centris bees Pérez published more than 100 articles and notes, two of them containing Centris bees. The first paper was published in 1905 and it contained the description of two new species from Mexico. The second article was published in 1911 and contained the description of a new species from northern Chile.	en	Vivallo, Felipe (2023): The primary types of some species of Centris bees described by European entomologists in the 18 and 20 centuries (Hymenoptera: Apidae).

Diguet traveled to Mexico where he worked as a chemical engineer. During this stay, as well as following six trips he made to this country, he collected specimens for the MNHN.

03CB8782FFE5DA1DAD3FF9365DC1FCDB.taxon	description	Josef Anton Maximilian Perty Josef Anton Maximilian Perty (1804 – 1884) was a German naturalist and entomologist. He was a professor of zoology at Ludwig-Maximilian-Universität München, and at Universität Bern, Switzerland (Hess 1887). Throughout his professional life, Perty published numerous articles on a wide variety of topics. All of them testify of a strictly scientific education, a wide knowledge of literature and a keen capacity for observation; but unfortunately, especially in his later years, also of a tendency towards miraculous and spiritualistic visions (Hess 1887). Perty passed away in Bern, aged 80. Perty’s Centris bees Perty described a single species in Centris that was later transferred to Eufriesea Cockerell, 1908 (Apidae: Euglossini), and three species in Xylocopa Latreille, 1802 (Apidae: Xylocopini) that were later transferred to Centris. The type specimens of these species were collected by the German naturalist Johann Baptist von Spix (1781 – 1826) and the German doctor, botanist and anthropologist Carl Friedrich Philipp von Martius (1794 – 1868) during an expedition to Brazil.	en	Vivallo, Felipe (2023): The primary types of some species of Centris bees described by European entomologists in the 18 and 20 centuries (Hymenoptera: Apidae).

He descended from a rich and powerful family from Italy, with lands in Europe and South America, from which he received many insects. Thanks to his wealth, Spinola made extensive purchases of insect collections (Gestro 1915), which allowed him to make important contributions to the taxonomy of the orders Coleoptera, Hemiptera and Hymenoptera. He passed away in Tassarolo, Italy, aged 77. Spinola’s Centris bees Spinola proposed six new species in Hemisia, at that time considered the valid name for Centris. According to Moure et al. (2007) the primary types of four of those species are housed at MSNT, but unfortunately, they were not available during the preparation of this article.	en	Vivallo, Felipe (2023): The primary types of some species of Centris bees described by European entomologists in the 18 and 20 centuries (Hymenoptera: Apidae).

Embrik Strand Embrik Strand (1876 – 1947) was a Norwegian botanist, entomologist, arachnologist and naturalist. Between 1901 and 1903, he worked as curator in the Museum of Zoology of the Universitetet i Kristiania, currently Universitetet i Oslo (University of Oslo), Norway. Later he moved to Germany to continue his studies in zoology. In Norway, Strand worked at different museums and universities until 1923, when he moved to Latvia. There he worked as professor of zoology at the Rīgas Universitāte, currently Latvijas Universitāte (University of Latvia) (Natvig 1944). Specimens of the Strand’s collection can be found in the Zoological Museum of the University of Oslo, and in the ZMB. Strand passed away in Riga, Latvia, aged 71. Strand’s Centris bee Strand described a single taxon in Centris, the variety C. sponsaasuncionis Strand, 1910. The description was based on specimens collected by the Hungarian pharmacist, biologist, botanist and researcher János Dániel Anisits (1856 ‒ 1911). Anisits migrated to Paraguay after he graduated as a pharmacist in Budapest (Vivallo 2020 d). In this country he worked actively, collecting biological material and discovering several new species, mainly plants (Magyarország és Latin-Amerika 2019). This variety remained forgotten until it was cited by Moure et al. (2007) as junior synonym of C. sponsa Smith, 1854. Despite the similarity between them, they seem to be different species. Here, it is proposed to withdraw C. sponsaasuncionis from the synonymy of C. sponsa, revalidate it and raise it to species level.	en	Vivallo, Felipe (2023): The primary types of some species of Centris bees described by European entomologists in the 18 and 20 centuries (Hymenoptera: Apidae).

Thanks to his contact with the French entomologist and carcinologist Eugène Louis Bouvier (1856 ‒ 1944), former chair of entomology at the MNHN, Vachal started working at the Museum, deciding that after his death, his entire entomological collection would be donated to that institution (Rasmussen 2012). He passed away in Argentat, France, at the age of 72. Vachal’s Centris bee Vachal described Centrisautrani Vachal, 1904 based on specimens collected by the French naturalist Gustave-Adolphe Baer (1839 ‒ 1918) between 1902 and 1903 in northern Argentina. The name of this species was in homage of his friend and colleague the Austrian botanist Eugène John Benjamin Autran (1855 ‒ 1912), at that time, a senior official of the Ministry of Agriculture of Argentina.	en	Vivallo, Felipe (2023): The primary types of some species of Centris bees described by European entomologists in the 18 and 20 centuries (Hymenoptera: Apidae).

Type data Vachal described this species based on two females and one male from Argentina and one female from Arica, Chile. Apparently, this type series was composed by at least two species, because C. autrani (= C. flavohirta) does not occur in Chile (Vivallo 2020 b). Unfortunately, the female from Chile was not found during the preparation of this paper. The rest of the type series, including the lectotype male designated by Zanella (2002) is housed at MNHN.

John Obadiah Westwood John Obadiah Westwood (1805 ‒ 1893) was an English entomologist, archaeologist and the first appointed curator of the Hope Entomological Collections at the Oxford University Museum of Natural History (Anonymous 1893). Westwood was one of the first entomologists with an academic position at the University of Oxford. He donated to that institution his insect collection which was later incorporated to the Hope Collection (Wandolleck 1894). Westwood died in Oxford, aged 87. Westwood’s Centris bee Westwood described a single species in Centris, based on an undetermined number of specimens that belonged to the collection of the British entomologist and naturalist Frederick William Hope (1797 ‒ 1862). In 1849, Hope gave his entire collection of insects to the University of Oxford (Baker 1994), which included the specimens studied by Westwood. Currently, it is formally known as the Hope Entomological Collections and it is held by the Oxford University Museum of Natural History (OUMNH).	en	Vivallo, Felipe (2023): The primary types of some species of Centris bees described by European entomologists in the 18 and 20 centuries (Hymenoptera: Apidae).
