Sleeping with the enemy: case reports of Ornithonyssus bursa (Berlese, 1888) (Mesostigmata: Macronyssidae) causing human dermatitis in Brazil

Ornithonyssus bursa, known as the “tropical fowl mite,” is a hematophagous mite of domestic and wild birds, which occasionally bites humans. Accidental bites on humans occur mainly when abandoned bird nests are close to homes or when people are handling parasitized birds. In the present study, we describe five case reports of bites on humans and new records of localities for this species. Based on the material examined, we provide morphological and molecular characterizations for this species herein.

The genus Apenesia is a parasitiod of beetles that live in galleries in dead wood or seeds.

Global guide of the flat wasps (Hymenoptera, Bethylidae)

The flat wasp family Bethylidae Haliday lacks global scale literature on their alpha taxonomy. The only world revision for the family was by Kieffer in 1914 and is fully out of date and somewhat useless; the only catalog for the family was made by Gordh Móczár in 1990 and does not include hundreds of changes made since then; and the most recent world genera keys were proposed by Terayama in 2003, but do not reflect the current knowledge we have for the family. Given this scenario, we present a global guide of Bethylidae with diagnoses, taxonomic evaluation, keys, and a checklist of all their extant genera and subfamilies. We visited the main collections around the world, analyzed about 2,000 holotypes, and examined at least 400,000 specimens. To eliminate homonymies, we add the prefix "neo" to the original specific epithet when possible. The family is now composed by 2,920 species allocated in 96 genera distributed in eight subfamilies: Bethylinae, Pristocerinae, Epyrinae, Mesitiinae, Scleroderminae, Lancepyrinae, Holopsenellinae and Protopristocerinae. The latter three are extinct. One new family-group synonym is proposed: Fushunochrysidae Hong syn. nov. of Bethylidae. Two incertae sedis genera are allocated into Bethylinae: Cretobethylellus Rasnytsyn and Omaloderus Walker. One new genus-group synonym is revalidated: Pristepyris Kieffer stat. rev. from Acrepyris Kieffer. Sixteen new genus-group synonyms are proposed: Fushunochrysites Hong syn. nov. and Sinibethylus Hong syn. nov. of Eupsenella Westwood; Messoria Meunier syn. nov. of Goniozus Förster; Acrepyris Kieffer syn. nov. of Pristepyris Kieffer; Apristocera Kieffer syn. nov. and Parapristocera Brues syn. nov. of Pristocera Klug; Usakosia Kieffer syn. nov. of Prosapenesia Kieffer; Isobrachium Förster syn. nov., Leptepyris Kieffer syn. nov., Neodisepyris Kurian syn. nov., Rhabdepyris Kieffer syn. nov. of Epyris Westwood; Codorcas Nagy syn. nov., Hamusmus Argaman syn. nov. and Ukayakos Argaman syn. nov. of Heterocoelia Dahlbom; Domonkos Argaman syn. nov. of Incertosulcus Móczár; Ateleopterus Förster syn. nov. of Sclerodermus Latreille. One new genus-group synonym is revalidated: Topcobius Nagy syn. rev. of Sulcomesitius Móczár. One new genus-group revalidation is proposed: Incertosulcus Móczár stat. rev. from Anaylax Móczár. The following species-group nomenclatural acts are established: 153 new or revalidated combinations, 16 new names to avoid secondary homonyms, 11 species with revalidated status, and one synonym. Keys to the subfamilies and genera are provided. The text is supported by 599 illustrations organized onto 92 plates.

New species and records of Dissomphalus Ashmead (Hymenoptera, Bethylidae) from Cerrado, Caatinga and relicts of the Atlantic Forest from northeastern Brazil

The main goal of this paper is to study the Dissomphalus material deposited at the Coleção Zoológica do Maranhão (Maranhão, Brazil). The material was collected in six parks: Parque Nacional Chapada das Mesas, Parque Estadual do Mirador and Reserva Ecológica do Inhamum in the state of Maranhão; Parque Nacional Serra das Confusões and Parque Nacional de Sete Cidades in the state of Piauí, and Parque Nacional de Ubajara in the state of Ceará. Forty species are recognized from these six parks. Twenty-two of them are previously described species, namely: D. bifurcatus Azevedo, D. cervoides Azevedo, D. conicus Azevedo, D. curvilongus Azevedo, D. geniculatus Azevedo, D. gilvipes Evans, D. infissus Evans, D. krombeini Azevedo, D. laminaris Redighieri Azevedo, D. latimerus Azevedo, D. linearis Azevedo, D. lobisserratus Azevedo, D. magnus Redighieri Azevedo, D. megomphalus Evans, D. microstictus Evans, D. napo Evans, D. plaumanni Evans, D. scamatus Azevedo, D. subpilosus Azevedo, D. tubulatus Redighieri Azevedo, D. ubracus Brito Azevedo and D. verrucosus Redighieri Azevedo.

A key for these species is provided. The genus is newly recorded from the state of Piauí, Brazil.

Pairs in copulation of the highly dimorphic genus Pristocera Klug (Hymenoptera, Bethylidae) from Madagascar solve taxonomic problems of male-female associations

The main goal of this paper is to update the taxonomic information of the pairs of Pristocera Klug collected in Madagascar by A. Seyrig. Within this material twelve species are recognized, ten are new to science, all based on pairs collected in copulation, which are described and illustrated: P. melmani sp. nov., P. alexi sp. nov., P. martyi sp. nov., P. gloriae sp. nov., P. julieni sp. nov., P. morti sp. nov., P. mauricei sp. nov., P. makungai sp. nov., P. teetsii sp. nov. and P. zubai sp. nov.. Pristocera levicollis (Kieffer) had its female discovered, and P. cambouei Saussure stat. rev. had its lectotype designated. Sclerodermus hova Saussure is transferred back to Pristocera and considered as a junior synonym of P. cambouei. Keys for males and females to the species of Pristocera from Madagascar are provided. The Malagasy fauna of Pristocera is now represented by twelve species, all endemic to this island.

[Insect pests dissemination by extruded starch packages]

We observed the viability of extruded starch products used as impact protector for fragile packing as a food source of the following stored grains pests: Cryptolestes ferrugineus (Stephens), Lasioderma serricorne (Fabr.), Oryzaephilus surinamensis (L.), Sitophilus oryzae (L.), Tribolium castaneum (Herbst) (Coleoptera) and Plodia interpunctella (Hübner) (Lepidoptera). Cryptolestes ferrugineus, L. serricorne and T. castaneum were found in these products, which are used by them as shelter and food. Under experimentation, we observed the development of O. surinamensis, S. oryzae and P. interpunctella feeding on this food source. Thus, it is recorded the viability of such material to be a potential dispersal vehicle to spread insect pests.

[The genera of Bethylidae (Hymenoptera: Chrysidoidea) in four areas of Atlantic Rain Forest from Espírito Santo, Brazil]

The generic richness and abundance of Bethylidae collected in four different hillside areas of Atlantic rain forest from Espírito Santo, Brazil were studied. The sites are Santa Maria de Jetibá (SMJ), Domingos Martins (DM), Pancas (P) and Atílio Vivacqua (AV). A total of 2,840 specimens of 12 genera were collected. Lepidosternopsis Ogloblin and Bakeriella Kieffer are first recorded from the State. Richness of taxa was calculated using first-order Jackknife richness with EstimateS program. Genera accumulation curves were ran to evaluate the samples. Abundance data were adjusted to the geometric distribution. Parameter k was used to compare areas. The generic profile was not equal for the sites we studied. The areas were considered disturbed. SMJ and DM presented genera richness bigger than in P and AV. The differences in the sites reflect the different preservation of each environment. Pseudisobrachium Kieffer and Dissomphalus Ashmead are most dominant genera in SMJ, DM and P, and Anisepyris Kieffer in AV. This study emphasizes the fact of Dissomphalus as the most abundant genus in rain forests. The generic profile found in AV is similar to that of some areas of Brazilian savannah.
