The species Cultrobates heterodactylus Willmann, 1930 is known from Central America and has erroneously been reported from the Galapagos archipelago. A comparison with findings of this species from Panama has highlighted morphological differences between the specimens from Galapagos and C. heterodactylus. Herein, two new species from Galapagos, Cultrobates ermilovi n. sp. and Cultrobates subiasi n. sp. are described and illustrated. Also, differences in colonization of different islands as well as preferences in occupation of different habitats of the two species in Galapagos were noted, whereby C. subiasi was found almost exclusively in epiphytic habitats, predominantly in moss, and C. ermilovi occurs in various microhabitats in ground litter. Cultrobates heterodactylus occurs in Panama in lowland tropical rainforests, mainly in moist forest floor and litter in epiphytic bromeliads. Additional taxonomical remarks on C. heterodactylus are presented. Corrections to previous distribution data are given.

Mites occupy a wide range of ecological niches and are good models to investigate correlations of morphological structures and ecology in arthropods. Here we compare tarsal claw shape of three terrestrial oribatid mite species with different ecological backgrounds. By means of geometric morphometrics we describe shape, size and development of the tarsal claw of the monodactyl mite species Lamellovertex caelatus and Platynothrus peltifer, and the tridactyl Melanozetes meridianus. After analysis of juvenile and adult mites we can distinguish the euryoecious P. peltifer and the alpine M. meridianus with similar claw curvatures from the saxicolous L. caelatus with considerably less curved claws. The claw height of P. peltifer, on the other hand, is remarkably higher than in the other two species. Despite these differences, no correlation between claw characteristics and environmental factors can be inferred. During the development of the mites, claw curvature and shape remain constant from protonymph to adult and claw size increases direct proportionally with body growth in all studied species. Neither the monodactyl nor the tridactyl species show any specific changes in claw characteristics.

In an effort to understand the fauna of Gamasina (Mesostigmata) edaphic mites from Brazil, Arrenoseius robertogonzalezi Trincado and Martin, 2018, known only from the original description from Chile, was found. Complementary morphological information is provided for this species . Likewise, a new species, Chelaseius pluridentatus n. sp. was found and is here described; it is distinguished from other Chelaseius Muma and Denmark species mainly by having more teeth on the fixed cheliceral digit, seven instead of 2–5. A key to the world species of Chelaseius is also provided.

Varroa destructor is one of the most devastating ectoparasites of the honey bee, Apis mellifera, worldwide. Given that V. destructor has very low survivability and exhibits no successful reproduction away from their natural environment and host and that the availability of mites for experimental purposes is limited by seasonality, several protocols of mite rearing under laboratory conditions have been developed. However, only one of these rearing systems has been able to yield a fertile second generation with a low mite survival. The aim of this study was to develop a semi-field rearing method to obtain mites of known age and life cycle that can be maintained through several generations. We registered and compared survival and reproductive parameters of mites of controlled age during four generations (P, F1, F2, F3) and evidenced no significant differences between these mite groups for these life-history traits. With present results we demonstrate that it is possible to successfully produce a third generation of mites under semi-field conditions. This study brings useful information about key conditions for the proper reproduction of mites in a controlled rearing system and provides a potential standardized method for V. destructor research, especially for host-parasite interaction experiments.

The first record is presented of the sejoid genus Uropodella (family Uropodellidae, suborder Sejida) from Baltic amber, based on a well-preserved adult male. Morphologically, the specimen is as modern in structure as adults of the six known extant species of Uropodella. The diagnosis of the fossil in distinction to the extant species justifies naming it as a new species. This record traces the genus back to the Eocene, representing the oldest validated age for a mesostigmatan genus. A key to species of the genus Uropodella is given.

Ixodes ricinus is an important vector of several human and veterinary infectious agents. Its wide geographical distribution and permissive feeding behaviour have prompted earlier studies on its population genetics. Results were, nevertheless, not conclusive. Furthermore, no research has fully focused on the south-western distribution range of I. ricinus, where exchanges between European and North African populations are more likely to occur. The presence of an additional species, Ixodes inopinatus, in the area further confuses the topic, as the two species are hard to differentiate morphologically. The present work describes the testing of microsatellite markers previously described for I. ricinus using Portuguese and Tunisian tick populations of both species. In addition, new microsatellite loci were developed to complement the available marker toolbox. Loci showed different amplification successes across subpopulations, with Tunisian DNA less readily amplified. Altogether, 15 loci were considered suitable for genetic analyses of Portuguese subpopulations, 10 for Tunisian samples, and seven, common to both populations, were considered to be informative at the inter-continental level. A preliminary analysis of both datasets revealed two isolated populations, which can correspond to two different species. Furthermore, Tunisian specimens identified by sequencing of 16S rDNA as having I. ricinus or I. inopinatus sequence profiles all clustered together in one single population using the proposed microsatellites. This confirms that taxonomic decisions based only on 16S rRNA gene sequencing can be misleading. The application of the proposed set of microsatellite markers to a larger sample, representative of the south-western Ixodes’ distribution range, will be crucial to clarify the distribution of both species.

We present results of the inventory of the spider mites of the Massane Forest Nature Reserve made during several field samplings from 2013 to 2017. Nineteen species have been recorded, which represents more than one third of the known spider mite fauna in France. Among them, three new species were disclosed and are described: Bryobia (Bryobia) alberensis sp. nov. collected on Phyteuma spicatum and Helichrysum stoechas, B. (Periplanobia) polymorpha sp. nov. on Genista pilosa and Tetranychus visigothus sp. nov., on Eryngium campestre, respectively. In addition, three spider mite species, Bryobia (Periplanobia) serifiotica, Eotetranychus aurantii and Eotetranychus fagi are recorded from France for the first time and three plant species are recorded as new host plants for tetranychid mites. The species delineation of B. (P.) polymorpha sp. nov., that presented large variation in dorsal setae length and shape, was investigated using a combination of morphological and molecular data. This approach allowed us to conclude that, despite such variations in a morphological key character, all the specimens observed belong to the same species.
