A new genus and species of Chironominae (Diptera: Chironomidae) with wood-mining larvae

Abstract  Xylochironomus kakadu , a new genus and species of wood-mining chironomid, is described from northern Australia. Formerly known by a code 'unknown genus K1', the larvae mine soft immersed timber in tropical Australia. The basal striae on the larval mandible are observed otherwise only in Chironomus Meigen and likely close relatives currently placed in Einfeldia Kieffer. The adult male could key as a tanytarsine, and all stages superficially resemble Polypedilum Kieffer, except for the bare squama and the non-tapered male tergite VIII, and the dorsal larval head sclerites. However, analyses of a morphological data matrix derived from all life history stages support no such relationships. Instead, a relationship to Paralauterborniella Lenz and Apedilum Townes, and at one remove, to Fissimentum Cranston & Nolte and Imparipecten Kieffer is postulated. Larval wood-mining among the early branching Chironomini is evidently frequent, but taxa appear not to form a monophyletic clade.     

Spiders of the genus Lachesana and a new storenoid genus from Israel (Araneae: Zodariidae)

Zodariid spiders of two genera in Israel are revised. The genus Lachesana is represented by two species. Only one male of these was ever depicted while the females of both and their hitherto unknown retreats were never described. Pax gen. nov. has been erected to accommodate five species, some of which have formerly been placed in Slorena, Selamia or Habronestes . Diagnostic characters of the West Mediterranean Selamia and the Australian Habronestes are newly illustrated. No drawings of Pax libani and P. islamita were ever published; the male of the latter is described here for the first time. Pax palmonii sp. nov. and P. engediensis sp. nov. are described and affinities of all taxa are discussed. Illustrations, records of distribution and keys to the species are provided.     

Two unusual Chironomini (Diptera: Chironomidae) from Australian rainforest streams: One new genus and a neotropical genus new for the region

Two genera of chironomine Chironomidae are reported: Anuncotendipes , gen. n., type species Anuncotendipes australotropicus sp. n. and included Anuncotendipes kakadu sp. n., and Nandeva Wiedenbrug, Reiss and Fittkau as new to Australia for the species Nandeva fittkaui sp. n. The pupa and adults are known for each genus, but the larvae only for Anuncotendipes . The female of Nandeva is described for the first time. Pupal exuviae of both genera occur in smaller streams in the wet tropics of Far North Queensland, and A. kakadu is lotic in the Northern Territory. Phylogenetic analysis of the subfamily Chironominae at generic level suggests that Anuncotendipes is a sister genus to Rheomus in the Harnischia -complex of genera. Nandeva shows convergent resemblance to the tribe Tanytarsini, but more likely belongs to an austral radiation of Chironomini including Nilodosis Keiffer, Fissimentum Cranston and Nolte and Imparipecten Freeman. These genera show tropical Gondwanan tracks linking Australia with the Afrotropics and Neotropics.     

Keraladiaptomus rangareddyi a new genus and new species of Diaptominae (Copepoda,Calanoida, Diaptomidae) from a temporary pond in Mattam,Kerala State,India

Calanoid copepods, belonging to the new genus and species Keraladiaptomus rangareddyi, were collected from temporary ponds in Kerala State, India. The new genus belongs to the family Diaptomidae, subfamily Diaptominae. It is described in detail and its affinity to the related genera, Arctodiaptomus Kiefer, 1932 and Eodiaptomus Kiefer, 1932, discussed.     

A new genus and species of heteronemertean from the Changjiang (Yangtze) River Estuary

A new genus and species of heteronemertean, Yinia pratensis gen. nov. and sp. nov., collected from low salinity waters (salinity 0.2–0.4 ‰) at Changjiang River Estuary, is described and illustrated. The species possesses a proboscis with an outer circular and an inner longitudinal muscle layer, and is placed in family Lineidae sensu Gibson. The following combination of morphological features distinguishes the new species from any other genera in this family: proboscis with two muscle crosses; dermis without connective tissue layer between gland cells and body wall outer longitudinal muscle layer; rhynchocoel wall circular muscles not interweaving with adjacent body wall longitudinal muscles; foregut with circular somatic muscles and subepithelial gland cell layer; neurochord cells present in central nervous system; caudal cirrus missing; blood system developed into alimentary plexus extending almost the full length of the body. Another significant character is that the lobular excretory cells are extremely well developed which may represent adaptation to water of low salinity. This revised version was published online in July 2006 with corrections to the Cover Date.     

Two new species of the orientalis group of Rheocricotopus (Psilocricotopus) from China (Diptera: Chironomidae)

Rheocricotopus (Psilocricotopus) calviculus sp. n. and R. (P.) villiculus sp. n. from China are described as male imagines. The species are closely related to the previously described R. (P.) orientalis Wang forming a new group, the orientalis group, which eventually may deserve the rank of subgenus or even genus. The group is distinguished by lacking a humeral pit, numerous sensilla clavata on third palpomere, cuneiform wings, no or few setae on squama, long legs, banded abdomen, very long inferior volsella, gonocoxite with apical extensions, and gonostylus with a median triangular projection.     

Allergens of non-biting midges (Diptera: Chironomidae): a systematic survey of chironomid haemoglobins

Various genera of non-biting midges (Diptera: Chironomidae) possess haemoglobins in larvae and adults. For certain species, these haemoglobins have been implicated in human allergic disease in several countries. The present study confirms and extends observations that haemoglobin is present in many species of Chironomidae, establishes that it is retained from the larval to the adult stage and shows that haemoglobin persists both in live and in dead dry flies. Previous suggestions that Chironomidae should be seen as important environmental and occupational allergens are clearly substantiated.     

Fissuroderes, a new genus of Kinorhyncha (Cyclorhagida) from the deep sea and continental shelf of New Zealand and from the continental shelf of Costa Rica

Specimens of Kinorhyncha collected by RV Sonne from the continental shelf off the coast of Costa Rica and from the deep sea East of New Zealand as well as by RV Kaharoa in the Firth of Thames are identified as five new species of a new genus Fissuroderes gen. nov. which is distinguished from all other kinorhynch genera by a ring-like cuticle in the first trunk segment and a cuticle with midventral and lateral articulations resulting in two sternal plates and one tergal plate in segments 2-10. Fissuroderes higginsi sp. nov. can be distinguished from all other species of Fissuroderes by a laterodorsal spine in segment 2 and the lack of a lateroventral spine in segment 8. Fissuroderes rangi sp. nov. is recognized from all other species by the lack of a ventrolateral spine in segment 2, the lack of a lateroventral spine in segment 5, an extremely elongate spinose tergal extension of segment 11 and a prominent midventral spinose process of the sternal plates in segment 11. Fissuroderes papai sp. nov. is identified by the short spinose process of the sternal plate of segment 11. Only Fissuroderes thermoi sp. nov. possesses bilobed sternal plates in segment 11 and a short conical tergal extension. Fissuroderes novaezealandia sp. nov. differs from F. higginsi sp. nov. in the lack of a laterodorsal spine in segment 2, the lack of an accessory spine in a lateral position in segment 8, the lack of a sublateral spine in segment 10, the existence of a lateroventral spine in segment 8 and in the lack of a subdorsal type 2-gland cell outlet in segment 2. The former species differs from F. papai sp. nov. in the lack of a lateroventral spine in segment 8, the lack of longitudinal indentations in the posterior part of the trunk cuticle of each segment and in the existence of an elongate spinose tergal extension of segment 11 and of many fine hairs on the surface of the cuticle. Fissuroderes is included into the Echinoderidae which is suggested to enclose also the genera Echinoderes and Cephalorhyncha. Echinoderes nybakkeni Higgins, 1988 is now combined as Cephalorhyncha nybakkeni (Higgins, 1988) comb. nov.
