a new genus and species of chiggers Trombidiformes leeuwenhoekiidae from peru
2021Co-Authors: Cal Welbourn, Ricardo Bassinisilva, Ron Ochoa, Pavel B Klimov, Barry M Oconnor, Darci Moraes Barrosbattesti, Matheus HuangbastosAbstract:South American chiggers have historically been poorly studied, and this has continued into present times. Of the 33 genera in the family Leeuwenhoekiidae Womersley, only Odontacarus Ewing and Sasacarus Brennan & Jones have been reported in Peru. Here, we describe a new genus, Peruacarus n. gen., and a new species, Peruacarus anthurium n. sp., parasitizing Koford's grass mouse, Akodon kofordi Myers & Patton, in Peru.

two new species of chiggers Trombidiformes trombiculidae from brazil
2021Co-Authors: Cal Welbourn, Ricardo Bassinisilva, Ron OchoaAbstract:Chigger mites are parasites of terrestrial vertebrates, including humans. Here, we describe two new species belonging to the American genera Colicus Brennan and Parasecia Loomis. Both species were described on the base of museum specimens originated from Minas Gerais State, Brazil, Colicus barrosbattestiae n. sp. parasitizing the rodent, Oligoryzomys fornesi and Parasecia jacinaviciusi n. sp. parasitizing the marsupial, Monodelphis domestica.

a new species of elianella vercammen grandjean Trombidiformes trombiculidae from the insular equatorial guinea with a key to the species into this genus
2021Co-Authors: Cal Welbourn, Ricardo Bassinisilva, Ron Ochoa, Darci Moraes Barrosbattesti, Matheus Huangbastos, Fernando De Castro JacinaviciusAbstract:The African continent has 452 chiggers (Trombidiformes: Trombiculidae) in 61 genera. One of these, Elianella Vercammen-Grandjean, 1956, has only two species known for Africa. The objective of the present study is to describe a new species for Equatorial Guinea, with the aim of increasing knowledge so scarce for Africa. In this study, we provide drawings, measurements and microscopy images on a Microscope Zeiss for the new species described below. Also, this type of the new species is deposited in the USNM. We describe a new species of Elianella collected parasitizing the Bioko Forest Shrew, Sylvisorex isabellae Heim de Balsac (Eulipotyphla: Soricidae) from the insular Equatorial Guinea. Also, we are providing a key for the three species of Elianella. Finally, we are contributing to the knowledge of African species, due the fact this new species is the first chigger recorded to the Equatorial Guinea, on the west coast of Central Africa.

a new genus of chiggers Trombidiformes trombiculidae from bats in jamaica
2021Co-Authors: Cal Welbourn, Ricardo Bassinisilva, Ron Ochoa, Darci Moraes Barrosbattesti, Matheus Huangbastos, Fernando De Castro JacinaviciusAbstract:The Caribbean country Jamaica has only seven reported chigger species. Of these, one was recorded from bats. For the specimens examined in this study were provided drawings, measurements, and microscopy images on a Microscope Zeiss. This material is deposited in the Smithsonian National Chigger Collection. In the present study, we describe a new genus and species parasitizing the Antillean ghost-faced bat in Jamaica. This new genus can be separated from all other genera of this family for the following combination of features: (1) palptarsus with four branched and three nude setae; (2) 3-pronged odontus; (3) femur I divided into basifemur and telofemur; and (4) 3 σ on genu I. The description of this new genus contributes to the increase in the knowledge of chiggers that parasites bats in Jamaica. Also, this is only the second record of a chigger parasitizing this host in this country.

redescription of brennanacarus annereauxi Trombidiformes trombiculidae with new records for uruguay
2020Co-Authors: Cal Welbourn, Ricardo Bassinisilva, Ron Ochoa, Darci Moraes Barrosbattesti, Matheus Huangbastos, Fernando De Castro JacinaviciusAbstract:Brennanacarus annereauxi (Brennan and Yunker, 1969) was described from Venezuela parasitizing the greater spear-nosed bat. The monotypic genus Brennanacarus Goff, Yunker and Wheeler, 1987 is a replacement name for Nasicola Brennan and Yunker, 1969, which was preoccupied by Nasicola Yamaguti, 1968. Here, we redescribe the genus Brennanacarus and the type species B. annereauxi. Also, this is the first record of this species, as well as the second record of any chigger, for Uruguay.

description of leptus leptus haitlingeri n sp Trombidiformes erythraeidae parasitising horse flies diptera tabanidae and a key to the larvae of leptus spp in brazil
2019Co-Authors: Fernando De Castro Jacinavicius, Cal Welbourn, Ricardo Bassinisilva, Joao Fabio Soares, Flavia Virginio, Darci Moraes BarrosbattestiAbstract:The genus Leptus Latreille, 1796 (Trombidiformes: Erythraeidae) is represented by more than 250 species worldwide, and the larval stages of these mites are ectoparasites of many arthropod orders. In Brazil, there are 12 species of Leptus, some of which have been reported parasitising representatives of the orders Opiliones, Araneae, Coleoptera, Heteroptera, Hymenoptera and Diptera. This paper describes Leptus (Leptus) haitlingeri n. sp. collected from horse flies (Diptera: Tabanidae) in the state of Sao Paulo, Brazil. The new species is distinguished from L. (L.) adaminae Haitlinger, 2004 and L. (L.) fozicus Haitlinger, 2004 by the presence of 4 branched setae on palptarsus (vs 2 branched setae). A key to the larvae of Leptus spp. in Brazil is provided.

A Revision of Parasecia (Trombidiformes: Trombiculidae) With a Description of a New Species, a New Genus and a Key to Species.
2021Co-Authors: Ricardo Bassini-silva, Fernando De Castro Jacinavicius, Cal Welbourn, Ronald Ochoa, Mariana De Souza Oliveira, Laura Contreras Peinado, Claudenice Faxina, Luciano Moreira-lima, Erich Fischer, Erika Hingst-zaherAbstract:Chiggers of the genus Parasecia Loomis parasitize birds, mammals, and reptiles in the Nearctic and Neotropical regions. In the present review, we examined 18 species previously included in the genus, 15 of them being retained in the genus Parasecia, one genus is created, Nahuacarus bulbocalcarn. gen. (Trombidiformes: Trombiculidae), and new combinations are proposed for two species: Lorillatum lasiurusn. comb. and Lorillatum orphanan. comb. (Trombidiformes: Trombiculidae). In addition, Parasecia kansasensis (Loomis) (Trombidiformes: Trombiculidae) is synonymized with Parasecia gurneyi (Ewing) (Trombidiformes: Trombiculidae), Parasecia gilbetoin. sp. (Trombidiformes: Trombiculidae) is described and new locality and host records are added for Parasecia chara (Wharton), Parasecia longicalcar (Brennan and Jones), Parasecia manueli (Brennan and Jones), and Parasecia thalurania (Brennan) (Trombidiformes: Trombiculidae).
