A new genus and species of pseudothelphusid crab of the tribe Kingsleyini Ortmann, 1897, from the Tapajós River, a southern tributary of the Amazon River basin in the state of Pará, Brazil, is described and illustrated.Michaelthelphusa tuerkayigen. et sp. nov. is characterized by the male first gonopod possessing marginal and lateral sutures fused at the distal third of the stem and the merged portion strongly twisted towards the lateral side; an apex transversally expanded along caudal-cephalic axis, with a well-developed, but low, somewhat depressed, apical plate; apical plate with spine-like outgrowth cross overlapping the spine-like projection of the mesial process. Moreover, the relationship of the new genus and species with other pseudothelphusid genera from the Amazon basin is discussed.

Abstract A new genus and species of gecarcinucid crab are described here from the Namdapha Tiger Reserve of Arunachal Pradesh, India; Abortelphusa namdaphaensis gen. et sp. nov. is morphologically distinct from other related genera, like Phricotelphusa Alcock, 1909, Globitelphusa Alcock, 1909, Liotelphusa Alcock, 1909, and in having a discrete suite of characters, i.e., carapace squarish, surface randomly pitted, a wide frontal margin ca. 0.5 times the total carapace width; epigastric cristae rugose, post orbital cristae indiscernible; third maxilliped exopod lacking a flagellum; male pleon narrowly triangular, sixth pleonal somite trapezoidal; terminal segment of male first gonopod subcylindrical, outwardly bent, tip not truncated. The relationship of this new genus and species with other gecarcinucid genera from India is discussed.

Calixomerialasalleigen. n. et sp. n. is described as a new genus and species of Sceliotrachelinae. Calixomeria most closely resembles genera of the Aphanomerus-cluster but possesses several characters that readily separate it from other sceliotracheline genera. The key of Masner and Huggert (1989) is modified to accommodate Calixomeria, and the relationship of the genus to other members of the subfamily is discussed.

The new genus and species, Phlebotoiella eoindianensis, from the Eocene Vastan amber deposits in western India is described and illustrated. This marks the first Psychodidae to be described from Vastan amber. The relationship of this new genus is discussed as well as its biogeographic implications.

Leprosa milga Kim & La Salle gen. & sp. nov. (Hymenoptera: Eulophidae: Tetrastichinae) is described from Eucalyptus seed capsules. The new species is an Australian seed gall inducer which has become established in South Africa and Italy. The relationship of Leprosa to two other genera of seed gall inducing tetrastichines, Quadrastichodella and Moona, is discussed.

One new cicada genus Versicolora gen. nov. and two new species, V. ziyongi sp. nov. from China and V. bellula sp. nov. from China and Vietnam, are described. The new genus is placed in the tribe Leptopsaltriini of the subfamily Cicadinae. The relationship of this new genus to other related taxa is discussed. Versicolora ziyongi sp. nov. camouflages itself on the bark of the host-plants and gradually changes its body colour when captured. This colour-changing behaviour is recorded for the first time in Cicadoidea, which provides innovative information for ecomorphological study of this remarkable species and other cicadas that potentially exhibit this behaviour.

One individual referable to Calliopiidae G.O. Sars, 1893 was collected from a chemically reduced habitat, the hydrothermal vent systems in Okinawa Trough, and was identified as a new genus and species belonging to this family after a morphological examination. A formal description of this new species and a discussion of the relationship of the new genus within Calliopiidae are presented.

AbstractThe crustose lichen genus Mycoblastus in the Northern Hemisphere includes eight recognized species sharing large, simple ascospores produced 1–2 per ascus in strongly pigmented biatorine apothecia. The monophyly of Mycoblastus and the relationship of its various species to Tephromelataceae have never been studied in detail. Data from ITS rDNA and the genes coding for translation elongation factor 1-α and DNA replication licensing factor mini-chromosome maintenance complex 7 support the distinctness of Mycoblastus s. str. from the core of the Tephromelataceae, but recover M. fucatus and an undescribed Asian species as strongly supported within the latter group. We propose accommodating these two species in a new genus, Violella, which is characterized by its brownish inner ascospore walls, Fucatus-violet hymenial pigment granules and secondary chemistry, and discuss the position of Violella relative to Calvitimela and Tephromela. We describe the new species Violella wangii T. Sprib. & Goffinet to accommodate a new species with roccellic acid from Bhutan, China, India and the Russian Far East. We also exclude Mycoblastus indicus Awasthi & Agarwal from the genus Mycoblastus and propose for it the new combination Malmidea indica (Awasthi & Agarwal) Hafellner & T. Sprib.

A new genus and species of the lacewing family Psychopsidae, Electropsychops handlirschi gen. et sp. nov., is described based on a well preserved male specimen from the mid-Cretaceous amber of Myanmar. The new genus possesses a number of diagnostic characters of Psychopsidae, i.e., the lack of a forewing median nygma, the presence of a vena triplica, and the straight and barely forked RA. However, it also exhibits some remarkable characters that are present in Osmylopsychopidae, such as the distally narrowed forewing costal space and the sigmoid MA stem in the hind wing. The relationship between Psychopsidae and Osmylopsychopidae is briefly discussed.
