The Family

A cladistic analysis of the genera of the family ‘Lafoeidae’ was performed in order to investigate suprageneric classifications and the boundaries of the family, as well as to organise the available morphological data and discuss the possible evolution of some morphological characters. Our results suggest that the former ‘Lafoeidae’ must be separated into two families: the Hebellidae and the Lafoeidae (including the subfamilies Lafoeinae and Zygophylacinae).

Phylogenetic Hypotheses

Andersen's 1912 monograph on megachiropterans remains the definitive work on the systematics of this group. Andersen argued that the Macroglossinae, containing the eonycterine and notopterine sections, are a monophyletic sister-group to other fruitbats (i.e. Andersen's Rousettus, Cynopterus and Epomophorus sections). Two recent molecular studies (DNA hybridisation and restriction mapping of ribosomal cistrons), as well as an analysis of female reproductive characters, challenge the monophyly of the Macroglossinae and several of Andersen's other conclusions such as the phylogenetic position of Nyctimene. We performed a cladistic analysis on 36 morphological characters, including 33 that were gleaned from Andersen, to determine whether phylogenetic hypotheses based on modem phylogenetic methods are in agreement with Andersen's original conclusions and to compare morphological and molecular phylogenetic hypotheses. Minimum-length trees based on parsimony are largely consistent with Andersen and support (1) a monophyletic Macroglossinae, within which the eonycterine section is paraphyletic with respect to a monophyletic notopterine section, (2) a monophyletic Cynopterus section, excepting the exclusion of Myonycteris, (3) a monophyletic Epomophorus section, excepting the exclusion of Plerotes, and (4) a paraphyletic Rousettus section, with several of the Rousettus-like forms branching off near the base of the tree. Bootstrapping analyses on a reduced data-set that included taxa shared in common with the DNA hybridisation study did not provide strong support (greater than or equal to 95%) for any clades but did provide moderate support (greater than or equal to 70) for several clades, including a monophyletic Macroglossinae. These findings are in marked contrast to the DNA hybridisation phylogeny. A high index of between-data-set incongruence is further evidence for the clash between DNA hybridisation and morphology. A phylogenetic framework was constructed on the basis of morphological data and DNA hybridisation data using a criterion of moderate support and shows little resolution, whereas employing a criterion of strong support produced a framework resolving several additional nodes. One implication of this framework is that characteristic macroglossine features such as a long tongue with a thick carpet of filiform papillae have evolved independently on several occasions (or evolved once and were lost several times). Rates of character evolution for the morphological characters employed in our analysis were calculated using divergence times estimated from DNA hybridisation data. Rates have apparently been fastest in the interior branches, and slower along the external branches, which suggests an early adaptive radiation in the history of fruitbats.

This study examines the phylogeny, taxonomy, distribution and biology of the gasteruptiid subfamily Hyptiogastrinae and, at the same time, presents an overview of the family. Following a cladistic analysis of 35 discrete morphological characters, two monophyletic genera are recognised, Hyptiogaster Kieffer and Pseudofoenus s. l. Kieffer. As a consequence, the genera Aulacofoenus Kieffer, Crassifoenus Crosskey, and Eufoenus Szépligeti are synonymised with Pseudofoenus. A total of 88 species are recognised for the subfamily, 10 species of Hyptiogaster, which are restricted to mainland Australia, and 78 species of Pseudofoenus, 40 of which are described as new. Pseudofoenus has a restricted Gondwanan distribution and is found in Australia including Tasmania (65 spp.), New Guinea and New Britain (5 spp.), the south-west Pacific (New Caledonia, New Hebrides and Fiji – 2 spp.), New Zealand (4 spp.) and South America (2 spp.). No new species have been recorded from either New Zealand or South America. For Pseudofoenus, information on the distribution of each species, their biology (if known) and an identification key are presented.Following a taxonomic revision, the following new species are described: P. baileyi, sp. nov., P. baitetaensis, sp. nov., P. beverlyae, sp. nov., P. caperatus, sp. nov., P. cardaleae, sp. nov., P. carrabinensis, sp. nov., P. claireae, sp. nov., P. collessi, sp. nov., P. coorowensis, sp. nov., P. crosskeyi, sp. nov., P. douglasorum, sp. nov., P. eliseae, sp. nov., P. ericae, sp. nov., P. eustonensis, sp. nov., P. feckneri, sp. nov., P. gressitti, sp. nov., P. gullanae, sp. nov., P. hackeri, sp. nov., P. imbricatus, sp. nov., P. iqbali, sp. nov., P. kadowi, sp. nov., P. karimuiensis, sp. nov., P. kelleri, sp. nov., P. leinsterensis, sp. nov., P. macdonaldi, sp. nov., P. malkini, sp. nov., P. marshalli, sp. nov., P. masneri, sp. nov., P. mitchellae, sp. nov., P. morganensis, sp. nov., P. nalbarraensis, sp. nov., P. pumilis, sp. nov., P. schmidti, sp. nov., P. stevensi, sp. nov., P. tasmaniensis, sp. nov., P. taylori, sp. nov., P. umboiensis, sp. nov., P. walkeri, sp. nov. and P. zborowskii, sp. nov. The synonymy of Aulacofoenus, Crassifoenus and Eufoenus with Pseudofoenus result in the following new combinations: from Aulacofoenus: P. bungeyi (Jennings & Austin), comb. nov., P. deletangi (Schletterer), comb. nov., P. fallax (Schletterer), comb. nov., P. fletcheri (Jennings & Austin), comb. nov., P. goonooensis (Jennings & Austin), comb. nov., P. infumatus (Schletterer), comb. nov., P. kurmondi (Jennings & Austin), comb. nov., P. loxleyi (Jennings & Austin), comb. nov., P. marionae (Jennings & Austin), comb. nov., P. perenjorii (Jennings & Austin), comb. nov., P. swani (Jennings & Austin), comb. nov., P. thoracicus (Guérin Menéville), comb. nov., P. whiani (Jennings & Austin), comb. nov. and P. wubinensis (Jennings & Austin), comb. nov.; from Crassifoenus: P. houstoni (Jennings & Austin), comb. nov., P. grossitarsis (Kieffer), comb. nov and P. macronyx (Schletterer), comb. nov.; and from Eufoenus: P. antennalis (Schletterer), comb. nov., P. australis (Westwood), comb. nov., P. crassitarsis (Kieffer), comb. nov., P. darwini (Westwood), comb. nov., P. extraneus (Turner), comb. nov., P. ferrugineus (Crosskey), comb. nov., P. floricolus (Turner), comb. nov., P. inaequalis (Turner), comb. nov., P. melanopleurus (Crosskey), comb. nov., P. minimus (Turner), comb. nov., P. nitidiusculus (Turner), comb. nov., P. patellatus (Westwood), comb. nov., P. pilosus (Kieffer), comb. nov., P. reticulatus (Crosskey), comb. nov., P. rieki (Crosskey), comb. nov., P. ritae (Cheesman), comb. nov. and P. spinitarsis (Westwood), comb. nov.

A new species, Neogreenia lonicera Wu & Nan, is described and illustrated based on the adult female, second-instarfemale and first-instar nymph. This new species was collected at Helan Mountain, Inner Mongolia, China, in bark crevicesof Lonicera microphylla (Caprifoliaceae). A key is provided to separate the five species now known in NeogreeniaMacGillivray. A cladistic analysis of morphological data from adult females and first-instar nymphs of 28 archaeococcoidgenera has Neogreenia in a clade with Jansenus Foldi and Neosteingelia Morrison and usually also with KuwaniaCockerell, and thus Neogreenia should be placed in the family Kuwaniidae. A key to distinguish the adult females of the four genera of the Kuwaniidae is provided.

Phylogenetic relationships within the “symmetrical” hermit crab family Pylochelidae were analyzed for 41 of the 45 species and subspecies currently considered valid. In the analyses, 78 morphological characters comprised the data matrix and the outgroup consisted of Thalassina anomala, a member of the Thalassinidae, and Munida quadrispina, a member of the Galatheidae. A poorly resolved strict consensus tree was obtained from a heuristic parsimony analysis of unweighted and unordered characters, which showed the family Pylochelidae and the subfamilies Pylochelinae and Pomatochelinae to be monophyletic taxa – the latter two groups had the highest Bremer support values. Additionally, while the subgenus Pylocheles (Pylocheles) was strongly supported, the subgenera Xylocheles, and Bathycheles were not. More fully resolved trees were obtained when using implied weighting, which recognized the monotypic subfamilies Parapylochelinae, Cancellochelinae and Mixtopagurinae. The subfamily Trizochelinae was found to have four distinct clades and several ambiguously placed taxa.

Phylogenetic relationships within the largest family of entodiniomorphid rumen ciliates, the Ophryoscolecidae, were inferred from comparisons of small-subunit ribosomal RNA gene sequences. These included three new sequences from Diplodinium dentatum (1638 base pairs (bp)), Eudiplodinium maggii (1637 bp), and Ophryoscolex purkynjei (1636 bp). Using morphological characters, Lubinsky constructed a cladogram of the Ophryoscolecidae, and on the basis of his analysis, he divided the family into three subfamilies (Entodiniinae, Diplodiniinae, Ophryoscolecinae) to reflect his "natural" groupings (G. Lubinsky. 1957. Can. J. Zool. 35: 141 – 159). Our cladistic analysis, based on the limited morphological and ultrastructural data available, indicates that there are no synapomorphies supporting the Diplodiniinae sensu Lubinsky. However, based upon the six 18S sequences for the Ophryoscolecidae, the rumen ciliates are monophyletic and fall into three distinct groups corresponding to Lubinsky's subfamilial division of the family. Our molecular analysis shows Entodinium to be the earliest branching rumen ciliate (subfamily Entodiniinae) and Eudiplodinium, not Diplodiium, branching first among the diplodiniines.

A cladistic analysis of the Empidoidea and basal lineages of the Cyclorrhapha, based on morphological characters, confirms the monophyly of both groups as well as that of the                    Eremoneura. The resulting final trees are used to revise the classification of the Empidoidea to include the following five families: Empididae, Hybotidae, Atelestidae (including Nemedininae n. subfam.), Brachystomatidae rev. stat. (comprising the subfamilies Brachystomatinae, Ceratomerinae and Trichopezinae), and Dolichopodidae s.lat. The family Microphoridae is not recognized, and the Microphorinae and Parathalassiinae are assigned to the Dolichopodidae s.lat. The Dolichopodidae s.str. includes 15 subfamilies that were previously recognized within the family. Within the Empidoidea we found support for Atelestidae as the sister group to the Hybotidae and for the monophyly of Parathalassiinae + Dolichopodidae s.str. The Empididae remains poorly defined and the genera Homalocnemis Philippi, Iteaphila Zetterstedt, Anthepiscopus Becker, and Oreogeton Schiner are classified as incertae sedis within the                   Empidoidea. In addition, the following higher taxa are proposed: Symballophthalmini n. tribe, Bicellariini n. tribe, Oedaleinae rev. stat., and Trichininae rev. stat., which are all assigned to the Hybotidae. The genus Sematopoda Collin is tentatively assigned to Trichopezinae, and Xanthodromia Saigusa is transferred from Hemerodromiinae to Brachystomatinae.        All morphological characters are extensively discussed and illustrated, including details of the antennae, mouthparts, internal thoracic structures, wings, and male and female terminalia. In addition, a key to families and unplaced genus groups of the Empidoidea is provided. Feeding habits are also discussed in terms of the empidoid ground plan condition.

Despite their great importance as pests of cultivated plants worldwide, members of the family Tetranychidae have never been subjected to a thorough cladistic analysis to reveal the history and relationships among related genera. Herein, we provide the first phylogenetic analysis and taxonomic review of species of the genera Aponychus, Paraponychus and Stylophoronychus using morphological characters. The results indicate a monophyletic clade uniting the aforementioned genera, although none of the three genera were recovered as monophyletic. We reinstate the tribe Aponychini as the taxon containing those three genera. Aponychus bambusae and A. aequilibris are herein considered junior synonyms of Stylophoronychus vannus and A. corpuzae, respectively.

The present study is a cladistic analysis of morphological characters focusing on the file of the mandible, the apices of the maxillae, the rupturing device on the maxillae, the internal structures of the mouthparts, and the external morphology of the labial segments as well as the distribution of labial sensilla in true water bugs (Hemiptera: Heteroptera, infraorder Nepomorpha). The study is based on data referring to sixty-two species representing all nepomorphan families (Heteroptera), together with one outgroup species representing the infraorders Gerromorpha (Mesoveliidae). The morphological data matrix consists of forty-eight characters. The present hypothesis supports the monophyly of the Nepomorpha and the monophyly of all families. The new modification in the systematic classification has been proposed: ((Nepidae + Belostomatidae), (Diaprepocoridae + Corixidae + Micronectidae), (Ochteridae + Gelastocoridae), Aphelocheiridae, Potamocoridae, Naucoridae, Notonectidae, and (Pleidae + Helotrephidae)).

A new species of marine Gastrotricha from the north coast of São Paulo state, Brazil, is described. Adults of Ptychostomella sebastiana sp. nov. are unique in that they possess a pair of dorsolateral “rod-like” cephalic sensory organs and subrectangular scales covering the lateral body surfaces. A cladistic analysis was performed to investigate the internal relationship of the representatives of the taxa based on morphological data. Our analysis supported the monophyly of the taxon Ptychostomella, but its internal phylogenetic relationships are not well established due to the low phylogenetic signal of morphological characters used in the present study.

The Status

The historical status of the family Platypodidae is reviewed and the family is revised. Results of a cladistic analysis based on 35 terminal taxa and 80 adult morphological characters show that the current placement of Platypodidae makes the subfamily Scolytinae paraphyletic. Moreover, several important genera included in Scolytinae are shown to be members of Cossoninae (i.e. the placement of Protoplatypus Wood and Phylloplatypus Kato in Cossoninae is confirmed). Based on these results, the status of Platypodidae as a family and subfamily is rejected, Scolytinae thereby becoming a monophyletic taxon. Araucarius groups in Scolytinae instead of Cossoninae in the analysis on a single step only, but it is suggested that it be retained in Cossoninae until this subfamily is submitted to a similar phylogenetic study. Three genera and four species of Cossoninae are described as new: Dobionus Kuschel, gen. nov.: type species D. araucarinus Kuschel, sp. nov. (with the inclusion of D. brachyrhinus (Montrouzier)); Coptonus Kuschel, gen. nov.: type species C. fijianus Kuschel, sp. nov. (with the inclusion of C. papuanus Kuschel, sp. nov.) and Dissostomus Kuschel, gen. nov.: type species D. hornabrooki Kuschel, sp. nov.
