Table Mountains

The unique character of biotas on table mountains (tepuis) is well documented for macroscopic organisms. However, much less is known about the microorganisms inhabiting these unusual and diverse biotopes. Previously, new algal and cyanobacterial taxa have been described from South American table mountains, providing evidence for the frequently disputed concept of microorganismal endemism. The present study adds additional support for this concept. A number of unusual microalgae were found during a 2012 expedition on the top of Churí-tepui (Chimantá Massif, Venezuela). These organisms were thoroughly examined and we herein propose the establishment of two new species of cyanobacteria—Schizothrix venezuelana sp. nov., Porphyrosiphon latissimus sp. nov., two diatoms—Eunotia churiensis sp. nov. and E. multirimoportulata sp. nov.; and one filamentous green alga, for which we also present molecular phylogenetic support, Ekerewekia churiensis gen. et sp. nov. (Chlorophyta). These novel species are morphologically unique and because no such forms have been reported elsewhere in the world, they are potentially endemic to tepuis.

Baetidae is one of the most diverse families of Ephemeroptera. In South America this family now encompasses 27 genera and more than 130 species. The Guyana region is known for its extraordinary diversity and high level of endemism, which is, above all, remarkable at the tops of the isolated flat-topped table mountains – tepuis. Recently various international speleological expeditions to Churí-tepui explored the cave systems of this mountain. Here we describe a new genus of Baetidae recently found during the mentioned expeditions to Churí-tepui and Auyán-tepui. Parakari n. gen. can be distinguish from the other genera of this family, among other characters, in the nymphs by the absence of abdominal gills I, tarsal claws with subapical denticle larger than the others, right mandible with prostheca bifid and pectinate and with incisors positioned in obtuse angle to mola area, lingua with a tuft of setae, segment II of maxillary palpi with a concavity and a hole apically and segment II of labial palpi with a strong distomedial projection. In the adults the hind wings are absent and genitalia with segment II of forceps with a constriction, segment III elongate and long. Two new species are included in this genus; each one was collected at different tepui. A key and illustrations are included.

With new material available of most stages of many known Australian Paracnephia, including new species, it is now clear that certain segregates warrant assignment to new genera. This applies to Paracnephia gladiator Moulton & Adler, a Western Australia simuliid with numerous unique character states. The species is fully redescribed and assigned to Bunyipellum nov. gen. A diagnosis is provided and relationships discussed, as is historical biogeography. Bunyipellum appears to be more closely related to elements of the South American simuliid fauna than to any other Gondwanan Australian species.

A new genus of the ant subfamily Leptanillinae, Furcotanilla gen. nov., discovered in southwestern China is described. The new genus is distributed in the Oriental region and belongs to the tribe Anomalomyrmini of Leptanillinae. A key to the 4 known genera of Leptanillinae of the world based on the worker caste is provided. Two new species of Protanilla collected from southwestern China, P. gengma sp. nov. and P. tibeta sp. nov., are described. The type-species of Protanilla, P. rafflesi Taylor, is also described based on the AntWeb images. A key to the 7 known species of Protanilla of the world based on worker and queen castes is prepared.

Two New Species

Five species of the family Odiidae (Amphipoda), including four new species, are recorded from Japan: Metodius cyanomaculatus sp. nov.; M. leucomaculatus sp. nov.; Postodius albifacies sp. nov.; P. sanguineus sp. nov.; and Antarctodius japonicus Ariyama, 2011. Morphological characters and coloration of these species are described in detail. Metodius gen. nov. is established for the two new species and is characterized by the very short and bare palp of the maxilla 1 and the large gnathopod 2 propodus. Keys to the odiid genera and the Postodius species in the world are provided. The genera can be distinguished from one another by the shapes of maxilla 1, maxilliped, pereopod 7, and telson. The Postodius species differs in the shapes of gnathopod 2, and pereopods 3, 7. Female of A. japonicus is firstly recorded. In this species, the presence of an accessory flagellum and a gill on the coxa 7 is confirmed.

The Linotetranidae (Acari : Tetranychoidea) is a poorly known group of cryptic false spider mites associated with grasses and sedges. We review the family at the world level, provide the first phylogenetic analysis of the family, and describe the first Australian representatives: Austrolinus, gen. nov. and two new species: A.��arenulus and A. kinnearae. Linotetranidae is redefined, and keys are provided for the families of the Tetranychoidea, and for all described genera and species of Linotetranidae.

A revised classification for the world jumping plant-lice (Hemiptera: Psylloidea) is presented comprising all published family and genus-group names. The new classification consists of eight families: Aphalaridae, Carsidaridae, Calophyidae, Homotomidae, Liviidae, Phacopteronidae, Psyllidae and Triozidae. The Aphalaridae, Liviidae and Psyllidae are redefined, 20 family-group names as well as 28 genus-group names are synonymised, and one replacement name is proposed [Sureaca nomen nov., for Acaerus Loginova, 1976]. Forty two new species combinations are proposed resulting from new genus-group synonymies and a replacement name. One subfamily and three genera are considered taxa incertae sedis, and one genus a nomen dubium. Finally eight unavailable names are listed ( one family-group and seven genus-group names).
