New species of the genus Troglocheles (Acari: Prostigmata: Rhagidiidae) from Oetztal Alps,Tyrol, with a key to adult species of the genus

Two new species of rhagidiid mites are described from Oetztal Alps, Tyrol, Troglocheles archetypica n. sp. and T. aggerata n. sp. Their interspecific relationships are discussed and two new species-groups, T. strasseri and T. vornatscheri, are defined. A key to the known adult species of the genus Troglocheles Zacharda is given. Phylogenetic and evolutionary relationships among the known talus- and cave-dwelling species of this genus are briefly outlined, including the possibilities of sympatric versus allopatric speciation.     

New troglobitic species of the genus Troglocheles (Acari: Prostigmata: Rhagidiidae) from caves in northern Italy and Austria,with a key to adult species of the genus

Three new troglobitic species of rhagidiid mites of the genus Troglocheles – two from northern Italy, Troglocheles quinquesolenidiata sp. nov. and T. lanai sp. nov., and T. christiani sp. nov. from Austria – are described. A key to adults of the known species of the genus Troglocheles Zacharda of the world is given. In these vicariant species the different apomorphic morphological traits, troglomorphisms, are discussed in aspects of allopatric speciation, climatic relict hypothesis and evolutionary processes of adaptation to specific niches and time of occupation of the subterranean habitat. All new taxa are authored by M. Zacharda only.

Phylogeny and character evolution of the marine mite genus Isobactrus (Acari: Halacaridae)

A morphology-based phylogenetic analysis of the 24 species of Isobactrus (Acari: Halacaridae) demonstrated three major monophyletic groups supported by synapomorphies. Each group is geographically distinct being tropical Pacific, North Atlantic and Holarctic. Character optimization indicates some evolutionary tendencies of character transformation. Reduction of idiosomal lateral setation, loss of setae on the genu and the addition of female subgenital setae are postulated synapomorphies congruent throughout the tropical lineage. Similarly, setal addition on the telofemur occurred in the North Atlantic lineage, while reduction of genital area sclerotization is recognized in a northern phyletic group.

A new species under the name Scaptognathus ventridiscus sp. nov. is described from Japan. It differs from its congeners by the possession of a ventral disc in the male, a peculiar arrangement of dorsal plates and dorsal setae, and unique leg chaetotaxy.     

Oribatid mites of Liebstadia (Acari: Oribatida: Scheloribatidae) from Mongolia,with notes on taxonomy of the genus

Three new species of oribatid mites belonging to the genus Liebstadia are described from Mongolia. The new species are characterized by the poorly developed pteromorphae; the club-shaped head of the sensilli; the absence of the dorsosejugal suture; the dorso-ventral thickness, and the length and arrangement of notogastral setae. In addition, L. similis (Michael, 1888) is redescribed and recorded for the first time in Mongolia. Protoribates serratomarginatus Mahunka, 1983 is synonymized with L. similis. A key to the known species of the genus Liebstadia is given.     

A survey of external morphology of mites of the superfamily Eupodoidea Banks, 1894 (Acari: Acariformes)

This paper represents the initial stage of a systematic study of the mite superfamily Eupodoidea Banks, 1894. For the first time a comprehensive account of external morphology is given with many structures being illustrated by scanning electron micrographs. Where homologies have been established, standardized notations are applied and compared with the terminology previously used by other authors.
