Biogeographic Analysis

The suborder Ingolfiellidea currently consists of 39 named species. An historical overview is presented and phylogenetic and biogeographic analyses are made. The result of the phylogenetic analysis suggests the definition of two new genera within an African freshwater group, namely Paraleleupia n. gen. and Proleleupia n. gen. Re-examination of a supposedly Italian relict species, Metaingolfiella mirabilis, with the aid of SEM techniques reveals a half-fusion of the head region with the first pereionite. The issue of the function of the ‘eyelobe’ is addressed and an explanation presented after examining with SEM such lobes in different species. Furthermore, additional descriptions are given based on the type-material of Metaingolfiella mirabilis, Trogloleleupia eggerti, Trogloleleupia leleupi, Ingolfiella littoralis, I. tabularis, I. margaritae, I. quadridentata, and I. abyssi. An attempt to relate the geographic distribution and ecological characteristics to the phylogeny of the Ingolfiellidea results in a paleogeographic scenario that points to a freshwater subterranean origin for the group that dates from at least Triassic times.

Identification Of Species

This paper presents a revision of Haplomesus Richardson, 1908 (Ischnomesidae). Poor character definition, ineffective diagnosis of the genus and inadequate or poor descriptions and illustrations have resulted in difficulties in identification of species and generic membership. This study is based on type material and descriptions in the literature and encompasses 28 species. Four new genera are created, justified by a phylogenetic analysis of 37 ingroup taxa and two outgroup taxa. Three species of the ingroup were excluded owing to missing data. Four species are retained in Haplomesus sensu stricto, two species are removed to Cornuamesus, gen. nov., 11 species are removed to Fortimesus, gen. nov. and 12 species are removed to Gracilimesus, gen. nov. One species, Haplomesus franklinae Merrin & Poore, 2003 is removed from the group and placed in Contrarimesus, gen. nov. with another species, Ischnomesus curtispinis Brandt, 1992. The species level is conferred on Haplomesus insignis orientalis Birstein, 1960. Haplomesus quadrispinosus sensu Brandt (1992) is removed from H. quadrispinosus (Sars, 1879) and Haplomesus ?gorbunovi sensu Svavarsson (1984) is removed from Gracilimesus gorbunovi (Gurjanova, 1946).

Middle and Upper Devonian members of the phyllocarid order Archaeostraca Claus, 1888, are analyzed in both a phylogenetic and biogeographic context. Results of the phylogenetic analysis show that the suborders Ceratiocaridina Clarke in Zittel, 1900, and Rhinocaridina Hall and Clarke, 1888, are paraphyletic as traditionally defined. The diagnoses of these suborders are revised and the use of the suborders Echinocaridina Clarke in Zittel, 1900, and Pephricaridina Van Straelen, 1933, is proposed. Ceratiocaridina now contains the family Ceratiocarididae Salter, 1860; Rhinocaridina contains the family Rhinocarididae Hall and Clarke, 1888; Echinocaridina includes the families Aristozoidae Gürich, 1929, Ptychocarididae n. fam., and Echinocarididae Clarke in Zittel, 1900; Pephricaridina includes the families Pephricarididae Van Straelen, 1933, and Ohiocarididae Rolfe, 1962. Generic definitions within the Rhinocarididae, in particular “Rhinocaris” Clarke in Hall and Clarke, 1888, are revised. The genus Echinocaris is redefined to include a monophyletic assemblage of species. Each of these clades is supported by several synapomorphies. Two new genera, Paraechinocaris and Carinatacaris, are proposed. Biogeographic analysis of this group reveals an extremely low rate of vicariant speciation, while episodes of range expansion are frequent. All occurrences of vicariance preceded the Late Devonian mass extinction. This may suggest a relationship between increased dispersal, diminished speciation, and the Late Devonian biotic crisis. Parallels between the Late Devonian mass extinction and the modern biodiversity crisis are suggested by the frequency of episodes of range expansion indicative of invasive species.

The Herefordshire (Silurian) Lagerstätte (approx. 430 Myr BP) has yielded, among many exceptionally preserved invertebrates, a wide range of new genera belonging to crown-group Panarthropoda. Here, we increase this panarthropod diversity with the lobopodian Thanahita distos , a new total-group panarthropod genus and species. This new lobopodian preserves at least nine paired, long, slender appendages, the anterior two in the head region and the posterior seven representing trunk lobopods. The body ends in a short post-appendicular extension. Some of the trunk lobopods bear two claws, others a single claw. The body is covered by paired, tuft-like papillae. Thanahita distos joins only seven other known three-dimensionally preserved lobopodian or onychophoran (velvet worm) fossil specimens and is the first lobopodian to be formally described from the Silurian. Phylogenetic analysis recovered it, together with all described Hallucigenia species, in a sister-clade to crown-group panarthropods. Its placement in a redefined Hallucigeniidae, an iconic Cambrian clade, indicates the survival of this clade to Silurian times.

Parsimony Tree

Bombyliinae, one of the largest subfamilies of Bombyliidae, including 78 genera assigned to four tribes, is distributed on all continents except Antarctica. Their larvae are parasitoids, and adults are important pollinators. The Australian Bombyliinae currently has 17 described genera and 87 described species. The purpose of this study is to establish the phylogeny of the Australian members of the subfamily Bombyliinae, including the boundaries and relationships of the genera, using morphological characters. One maximum parsimony tree was generated from 83 morphological characters scored for 50 species, representing all recognised genera and some unplaced species that we considered may represent new genera. Phylogenetic analysis recovered the relationships between the recognised Australian genera of Bombyliinae and clarified generic limits. The group comprises five main clades, with the genus Pilosia being sister to the remaining Bombyliinae. On the basis of this analysis, four new genera are described: Lambkinomyia Li & Yeates, gen. nov., Dissodesma Bowden & Li, gen. nov., Nigromyia Li & Yeates, gen. nov. and Robertsmyia Li & Yeates, gen. nov. Ten new species are described: Dissodesma immaculata Li & Yeates, sp. nov., Dissodesma flava Li & Yeates, sp. nov., Dissodesma smarti Li & Yeates, sp. nov., Nigromyia collessi Li & Yeates, sp. nov., Nigromyia crocea Li & Yeates, sp. nov., Nigromyia flavimana Li & Yeates, sp. nov., Nigromyia longistriata Li & Yeates, sp. nov., Nigromyia pantherina Li & Yeates, sp. nov., Nigromyia parva Li & Yeates, sp. nov. and Nigromyia tomentosa Li & Yeates, sp. nov. Two new junior synonyms are identified: Apiformyia is a junior synonym of Eristalopsis and Brychosoma is a junior synonym of Staurostichus. The following new combinations are proposed: from Apiformyia: Eristalopsis australis (Yeates), comb. nov.; from Bombylius: Dissodesma primogenita (Walker) comb. nov.; from Brychosoma: Staurostichus aureolatus (Walker), comb. nov., Staurostichus hilaris (Walker), comb. nov. and Staurostichus pictipennis (Macquart), comb. nov.; from Laurella: Robertsmyia pallidoventris (Roberts), comb. nov.; from Mandella: Lambkinomyia cinctiventris (Roberts), comb. nov., Lambkinomyia flavovillosa (Roberts), comb. nov., Lambkinomyia pallida (Roberts), comb. nov. and Lambkinomyia rubida (Roberts), comb. nov.; and from Meomyia: Mandella australis (Guérin-Méneville), comb. nov. http://zoobank.org/urn:lsid:zoobank.org:pub:E4A86A19-4AC3-498C-8BDF-B8B501E5A248

A New Species

A remarkable new species, Odonteus gandhara Carpaneto & Mignani, n. sp., is described from northern Pakistan. The holotype (adult male) and the paratype (adult female) are illustrated and compared with O. armiger (Scopoli, 1772) and O. orientalis Mittal, 1998, the only two species of this genus recognized in the Old World. Both O. armiger and O. orientalis have the eye not completely divided by the canthus and have a sensory area on the external side of the last antennomere (this character has never been discussed in the literature until now). These two character states in O. armiger and O. orientalis compel emendations to the definition of the genus. The new species has a great zoogeographical relevance because similar species occur in North America (O. obesus LeConte, 1859 and O. falli Wallis, 1928), and probably represents a relict species endemic to the Himalayan range.

Definition Of

With 193 described species, Chusquea is the most diverse bamboo genus in the Neotropical region. Brazil, with 48 accepted species and 44 of them endemic, is one of its major centers of diversity. Among the Brazilian species, C. anelythra was only superficially characterized in its original publication almost 200 years ago, without a clear definition of its type-material, description of culm leaves, or comments on its geographic distribution or related species. As the absence of such information has greatly complicated the taxonomic delimitation of C. anelythra, the major aim of this paper is to clarify the identity of this species based on fieldwork and herbarium investigation, providing an emended description, illustrations, and photos of this species. We also designate a lectotype for the name C. anelythra, and provide a morphological comparison with two similar members of the C. meyeriana informal group. Geographic distribution and conservation status are also updated for this species.

AbstractHemiphlebiidae are the most basal lestomorphan family following the latest phylogenetic analysis of the Zygoptera: this unique damselfly family today contains one relict species found in the wetlands of Australia. It was, however, very diverse and widespread during the Mesozoic. Nevertheless, very few species were known obscuring the origination and early evolution of the family. Here we propose a new stem hemiphlebioid taxon (Protohemiphlebiidae Zheng, Jarzembowski & Nel, fam. nov.) based on a new genus and two species: Protohemiphlebia zhangi Zheng, Jarzembowski & Nel, sp. nov. and Protohemiphlebia meiyingae Zheng, Jarzembowski & Nel, sp. nov. The new family shares the characters of both Hemiphlebiidae and Coenagrionoidea, but it is more closely related to Hemiphlebiidae in having the pterostigma with a ‘star-shaped’ microsculpture, and AA originating from the wing base slightly distal of Ax0. Protohemiphlebia Zheng, Jarzembowski & Nel, gen. nov. is further considered to belong to the stem group of Hemiphlebioidea, instead of belonging to the Hemiphlebiidae, in possessing pretibial combs and a weakly kinked RP1 below the Pt-brace. The new damselflies will help to calibrate the origin of Hemiphlebiidae, which could be earlier than their current oldest records in the Kimmeridgean (Late Jurassic).

Subtropical Species

The phylogenetic placement of Chapsa lamellifera, C. megalophthalma and Diploschistes ocellatus was studied using a dataset of five genetic markers (mtSSU, nuLSU, RPB1, RPB2 and ITS). As extratropical species occurring in Australasia, C. lamellifera and C. megalophthalma differ from other species in that genus by having relatively large ascomata with muriform ascospores and complex chemistry of either the protocetraric or stictic acids chemosyndrome. D. ocellatus is unique within Diploschistes, in lacking lateral paraphyses and containing the norstictic acid chemosyndrome. Previous phylogenetic analysis gave inconclusive results regarding the phylogenetic position of these taxa, and hence in the present study, a larger sampling of molecular markers was employed. Our results demonstrated that the two Chapsa species and D. ocellatus are not part of their current genera. Consequently, the new genera Gintarasia Kraichak, Lücking & Lumbsch and Xalocoa Kraichak, Lücking & Lumbsch are described to accommodate these species. The new combinations Gintarasia lamellifera (Kantvilas & Vězda) Kraichak, Lücking & Lumbsch, G. lordhowensis (Mangold) Kraichak, Lücking & Lumbsch, G. megalophthalma (Müll. Arg.) Kraichak, Lücking & Lumbsch and Xalocoa ocellata (Vill.) Kraichak, Lücking & Lumbsch are also proposed.

Since the phylogenetic analysis of the Herrichella clade (Ochlerini) new genera were described to fit monophyletic groups inferred and considered to be new taxa. The clade I supported by two synapomorphies of the female genitalia, grouped Alitocoris brunneus Sailer together to two new species. Alloeogyna gen. nov. is described here for this clade including the two new species Alloeogyna ampla sp. nov. and Alloeogyna poecila sp. nov. and a new combination is proposed for Alloeogyna brunnea comb. nov.. Also, Alitocoris maculosus Sailer recovered within the clade E in the Herrichella clade is here redescribed in the monotypic Sailerus gen. nov. resulting in the new combination Sailerus maculosus comb. nov..
