: The invertebrate collection of the Museo Argentino de Ciencias Naturales “Bernardino Rivadavia” (MACN-In) is one of the most important in Latin America. 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.

: Tityus trivittatus is considered the most medically important scorpion species of southern South America. In this contribution we redefine its taxonomy, redescribe the species and separate the southern populations as a new species, Tityus carrilloi n. sp. As a consequence of this description, the most medically important species of the region turns out to be the new species herein described. We also clearly establish the phylogenetic position of both species through a dated molecular phylogenetic analysis based on four genes. Finally, we discuss the differences of the venom between the two species, and the epidemiologic implications of our results on the scorpionism problem in the region.

This research aimed to determine the parasitic helminth fauna of Phyllostomid bats from Junin, Peru, as well as to prepare an updated check list of records made in Peru. 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. All the parasites mentioned in the paper are new records for the department of Junin, Peru.

Abstract. 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. El genero de aranas cangrejo Uraarachne Keyserling 1880, que actualmente comprende dos especies: U. longa Keyserling (especie tipo, de Brasil y recientemente registrada en Paraguay) y U. vittata (Caporiacco) de Guayana Francesa, se propone –sobre la base de varios caracteres de morfologia somatica y genital– como sinonimo anterior de Plancinus Simon 1886, conocido hasta la fecha por tres especies de Uruguay: P. runcinioides Simon (especie tipo), P. cornutus Simon y P. brevipes Simon (las tres se transfieren aqui a Uraarachne ).

摘要。1880年的Uraarachne Keyserling螃蟹蜘蛛属目前由两个物种组成：U.Longa Keyserling（类型物种，来自巴西，新记录自巴拉圭）和U.Vittata（Caporiacco），来自法国Guiana。Uraarachne是根据身体和生殖特征提出的，是Plancinus Simon 1886的高级同义词，来自乌拉圭的三个物种：P.Runcinioides Simon（类型物种），P.Cornutus Simon和P.Brevipes Simon（所有三个都转移到这里的Uraarachne）。Uraarachne Runcinioides（普朗西努斯类型物种）和U.Cornuta首次为阿根廷报道，并根据类型标本和新材料，包括第一个已知的雄性，重新描述。来自阿根廷的四个新物种被描述：U.Panthera，N.sp.和U.Ceratophrys，N.sp.（来自Missions省，均基于单个雄性标本），U.Toro，N.sp.（仅来自萨尔塔省，女性）和U.Kapiity，N.sp.（来自阿根廷查科省、科连特斯省和恩特雷里奥斯省，来自巴拉圭，基于两种性别）。另外两个物种被转移到乌拉拉赫内：Runcinia Plana Simon，以前只从巴拉圭的青少年中知道（这里首次描述的成年人，分布扩展到阿根廷中东部），Misumenoides variegatus Mello-Leitao，从圣达菲的全型男性中知道（这里首次描述的女性，分布扩展到巴拉圭和阿根廷布宜诺斯艾利斯）。Platyarachne Argentina Mello-Leitao和Erissoides Argentinus Mello-Leitao新与Uraarachne Runcinioides同义。正在讨论该属的关系，提出与Runcinia Simon的密切关系。总结。Aranas Crabra Uraarachne Keyserling 1880属目前由两个物种组成：U.Longa Keyserling（巴西的模式物种，最近在巴拉圭注册）和U.Vittata（Caporiacco），来自法属圭亚那，根据身体和生殖形态的各种特征，建议作为Plancinus Simon 1886的前同义词，迄今已为乌拉圭的三个物种所知：P.Runcinioides Simon（模式物种），P、Cornutus Simon和P.Brevipes Simon（三人在这里转移到Uraarachne）。Uraarachne Runcinioides（普朗奇努斯型物种）和U.Cornuta首次被引用用于阿根廷，并根据阿根廷收藏中最近发现的类型标本和材料重新描述，包括第一批已知的雄性。为阿根廷描述了四个新物种：U.Panthera，N.sp.和U.Ceratophrys，N.sp.（来自米西翁省，均基于雄性标本），U.Toro，N.sp.（来自萨尔塔省，只有一只雌性）和U.Kapiity，N.sp.（来自阿根廷查科省、科连特斯省和恩特雷里奥斯省，以及巴拉圭，基于两种性别）。此外，还有另外两个物种被转移到乌拉拉赫内：Runcinia Plana Simon，以前为巴拉圭青少年所知（成年人首次被描述，并将其已知分布扩展到阿根廷中东部），以及Misumenoides variegatus mello-Leitao，以前为圣达菲的男性全型所知（女性在这里首次被描述，将其已知分布扩展到巴拉圭和布宜诺斯艾利斯）。阿根廷的Platyarachne Mello-Leitao和Argentinus Mello-Leitao与Uraarachne Runcinioides同义。简要讨论了该属可能的亲缘关系，提出了与Runcinia Simon的可能亲缘关系。

A new subgenus of Megachile is described for the Neotropical Region. It is distributed in Argentina, southern Brazil, and Uruguay. The males of Joergensenella n. subg. run to Chrysosarus in available keys to subgenera of Megachile , and have been included as such in recent catalogs , while the females run in the keys, and have been included in catalogs, as Dasymegachile or Cressoniella . Association of sexes for all the species are presented for the first time. Besides the type species, M. joergenseni Friese, the following are included in the subgenus Joergensenella : M. bruneriella Cockerell, M. una Vachal, M. lujanense n. sp. (from Mendoza, Argentina), M. fidalgoi n. sp. (from Jujuy, Argentina), M. puntana , (from San Luis and Tucuman, Argentina), and M. yana n. sp. (from La Rioja, Argentina). Females of one of the species included, M. ( Joergensenella ) una , bear specialized hairs on the face for the collection of pollen from nototribic flowers. A key is presented to separate this species from other two Megachile in Argentina with a similar specialization: M. ( Dasymegachile ) schwimmeri Engel, and M. ( Cressoniella ) boliviensis Friese .

(Dasymegachile) schwimmeri Engel和M. (Cressoniella) boliviensis Friese。
