No. of bitstreams: 0 Previous issue date: 2021-01-01 Purpose: Euschoengastia Ewing is a chigger genus in need of revision as it historically has combined species solely on the presence of expanded prodorsal trichobothria. The objective of the present study is to describe a new genus to reallocate two North American Euschoengastia species, to start an organization into this genus. Methods : In this study, we provide drawings, measurements and microscopy images on a Microscope Zeiss for the two redescribed species. Results: After examining the types of the species Euschoengastia latchmani Brennan and Yunker and Euschoengastia obscura Wrenn and Loomis, we realized that it was necessary to create the new genus to relocate these two species, mainly based on the following characters: (1) the number of prongs on the odontus; and (2) ornamentation of the prodorsal sclerite. Conclusion: Goffacarus latchmanin. comb. and Goffacarus obscuran. comb. are redescribed here and to reallocate these two species the genus, Goffacarusn. gen. is proposed.

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.

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. Methods: 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. Results: 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. Conclusion: 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.

Unlike most terrestrial parasitengone mites (chiggers, erythraeids), known mostly from parasitic and easy-to-collect larvae, smaridid systematics are mainly based on the post larval instar. Larvae are rarely collected, and their biology and host associations are virtually unknown. Here we infer phylogenetic relationships of Smarididae based on 50 morphological characters using both larval and post larval instars, including data on the larval morphology of Trichosmaris obtained through rearing. The subfamily Smaridinae, as currently understood, was recovered paraphyletic: the genus Smaris was rendered as basal smaridid lineage, while the genus Fessonia (Smaridinae) was sister to Hirstiosomatinae, albeit with moderate support. Our analysis suggests that the genus Surasmaris Southcott, 1995 is a junior synonym of Trichosmaris Southcott, 1963 (syn. nov.), and two Sphaerotarsus species should be placed into Hirstiosoma: Hirstiosoma baenai (Mayoral & Barranco, 2017) comb. nov., Hirstiosoma quercus (Yazdanpanah, Saboori & Hakimitabar, 2016) comb. nov. Sphaerotarsus monticolus Southcott, 1997 and S. leptopilus were recovered as independent lineages, and hence, a new genus Southcottiana gen. nov. is proposed to include Southcottiana monticola comb. nov (Southcott, 1997). We describe two new species, Trichosmaris paulensis sp. nov. (adults, larvae) and T. calcarensis sp. nov. (larva), and present the first description of larval T. dispar, the type species of Trichosmaris, previously known only from post larval instars. Based on the above results, we give a key to larval genera of Smarididae and a key to species of Trichosmaris (larval and postlarval instars).

Chiggers have been studied throughout the world for their role in disease transmission. Venezuela has the largest chigger diversity in South America. In a review of Venezuelan genera, two monotypic genera described from Robinson's Mouse Opossum collected in Falcon State and after examination of the types of both genera, it was found that Delmohius hardyi Brennan and Goff and Carebareia johnstoni Goff and Brennan are the same species. Therefore, we are proposing the synonymy of Delmohius with Carebareia.

Their larval stage parasitizes different species of arthropods. Until date, 12 species of Leptus have been registered for Brazil. In this study, we identified for the first time a larva of Leptus parasitizing an adult Ornithodoros soft tick in Brazil. This is the first record of a mite parasitizing an argasid tick, and increases the known number of Leptus in Brazil to 13.

Mites in the family Trombiculidae sensu lato are parasites of terrestrial vertebrates, even humans, in their larval stage. There are more than 3,700 species of chiggers, and about one-third of these species are represented by type specimens in the Smithsonian Institution’s United States National Museum Entomology Collection. Here we provide a catalog of all primary and secondary type specimens of chiggers (holotype, paratype, syntype, lectotype, and paralectotype) housed in the collection. Listed herein are 1,026 type specimens with 645 representing holotypes, 782 paratypes, 69 syntypes, 19 lectotypes, and 16 paralectotypes of larvae, deutonymphs, and adult chiggers.

Of these, one was recorded from bats. Methods: 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. Results: 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. Conclusion: 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.

A checklist of the family Trombiculidae and Leeuwenhoekiidae is presented, containing 63 species in 30 genera of chiggers from 80 different hosts and 146 localities in Brazil. The type locality and depository are provided, including new locality and host records for the country.

Chiggers are ectoparasites of vertebrates and may cause trombiculiasis or transmit pathogens to their hosts. Specimens collected from rodents and marsupials were morphologically identified as Herpetacarus hertigi, Eutrombicula tinami, Kymocta sp., Quadraseta brasiliensis, Quadraseta falconensis, Quadraseta flochi, Quadraseta mackenziei, Quadraseta pazca, Quadraseta trapezoides, Quadraseta sp., Serratacarus sp., and Trombewingia bakeri. These mites were submitted individually to molecular analyses for the detection of bacteria of the genus Coxiella, Hepatozoon and Rickettsia. Samples were positive to Rickettsia only. Obtained sequences for the gltA (350 pb) and ompA (488 pb) genes were identical to “Candidatus Rickettsia colombianensi”, a species previously detected in ticks. In addition, molecular identification of mites based on 18S rDNA sequences are provided for H. hertigi, Kymocta sp., Q. brasiliensis, Q. pazca, Q. trapezoides, Quadraseta sp., and T. bakeri for the first time. This is the first report of the detection of a Rickettsia sp. in chigger mites collected on rodents in Brazil.
