It has more than 1411 type batches with ~90 type specimens of echinoderms. For the present study we analyzed 56 lots of crinoids from the MACN-In. We also checked and updated the identification, when necessary. Seven species belonging to 6 genera were identified; 23 specimens remain unidentified. The diversity of crinoids for Chile, Uruguay and Brazil and Antarctica is dis- cussed. The MACN-In has several lots of crinoids from different parts of the world and numerous specimens of the 2 representative species from Argentina, Isometra vivipara Mortensen, 1917 and Phrixometra nutrix (Mortensen, 1918). This is the first published inventory of crinoids from samples deposited at the MACN-In collection, which will be a useful tool for future studies regarding echinoderms, particularly crinoids.","PeriodicalId":39176,"journal":{"name":"Revista del Museo Argentino de Ciencias Naturales, Nueva Serie","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68257116","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thirty bats of 6 different species belonging to the family Phyllostomidae were captured in Chanchamayo, Junin, Peru. Regarding these species, Artibeus lituratus Olfers, 1818, A. planirostris (Spix, 1823) and Carollia perspicillata (Linnaeus, 1758) were parasitized by trematodes, Phyllostomus discolor (Wagner, 1843) by cestodes and A. lituratus, A. planirostris, Carollia benkeithi Solari & Baker, 2006, C. perspicillata, Glossophaga soricina Pallas, 1766 and P. discolor by nematodes. The mean abundance of infection was greater for the trematodes with 175 specimens, followed by the nematodes with 115 specimens. Twenty-six parasitic species were found in the literature in the checklist developed in this study. Litomosoides brasiliensis Almeida, 1936 was the endoparasite with the highest number of hosts, and the number of hosts with at least one parasitic occurrence is 23 bat species in the checklist.

The crab spider genus Uraarachne Keyserling 1880 currently comprises two species: U. longa Keyserling (type species, from Brazil, and newly recorded from Paraguay) and U. vittata (Caporiacco) from French Guiana. Uraarachne is proposed, on base of somatic and genitalic characters, as a senior synonym of Plancinus Simon 1886, known from three species from Uruguay: P. runcinioides Simon (type species), P. cornutus Simon, and P. brevipes Simon (all three transferred here to Uraarachne ). Uraarachne runcinioides (type species of Plancinus ), and U. cornuta are reported for the first time for Argentina and redescribed, based on the type specimens and new material, including the first known males. Four new species are described from Argentina: U. panthera , n. sp., and U. ceratophrys , n. sp. (from Misiones province, both on base of single male specimens), U. toro , n. sp. (from Salta province, female only), and U. kapiity, n. sp. (from the argentine provinces of Chaco, Corrientes, and Entre Rios, and from Paraguay, on base of both sexes). Two additional species are transferred to Uraarachne: Runcinia plana Simon, previously known only from juveniles from Paraguay (adults described here for the first time, and distribution extended to central-eastern Argentina), and Misumenoides variegatus Mello-Leitao, known from the holotype male from Santa Fe (female described here for the first time, and distribution extended to Paraguay and Buenos Aires, Argentina). Platyarachne argentina Mello-Leitao and Erissoides argentinus Mello-Leitao are newly synonymized with Uraarachne runcinioides . The relationships of the genus are breafly discussed, proposing a close relationship with Runcinia Simon. Resumen.
