Five new species of oribatid mite belonging to the Gondwanan genus Crotonia are described from South and Central America: C. macfadyeni sp. nov. from the Falkland Islands, C. carioca sp. nov. from Brazil, C. valdivia sp. nov. and C. wallworki sp. nov. both from Chile, and C. aculeata sp. nov. from Guatemala. The nymphal stages of C. macfadyeni are also described. The species-groups of Crotonia delineated by Luxton (1982) are redefined in relation to these new species and a re-evaluation of characters. Previously, the primary character for defining species-groups was the arrangement of the caudal apophyses. Greater emphasis is placed herein on the fusion of the dorsal shield with the rest of the notogaster and the presence or absence of a lateral hyaline region. The Nukuhivae group is merged into the Unguifera group (containing C. carioca sp. nov., C. cervicornia, C. melanesiae, C. nukuhivae and C. unguifera) and the Caudalis group into the Obtecta group (containing C. blaszaki, C. obtecta, C. pulchra, C. caudalis, C. cupulata, C. longibulba and C. tuberculata). The biogeography of Crotonia is re-assessed based on 43 recognised species. The redefined Obtecta group has a disjunct trans-Pacific distribution. The Unguifera group, present in the Neotropics, is also found in an arc from New Zealand to the Philippines and has also dispersed to the mid-Pacific Marquesas Islands. Three new speciesgroups are established. The Flagellata group, containing C. flagellata and C. reticulata, also has a disjunct trans-Pacific distribution. The Lanceolata group is dominated by species from oceanic islands and contains C. brassicae, C. lanceolata and C. perforata from St. Helena, C. brevicornuta from Campbell Island, and C. ovata from Tasmania. The Capistrata group contains those species which possess the full complement of setae in the c series (C. alluaudi, C. americana, C. ardala, C. borbora, C. capistrata, C. dicella, C. ecphyla, C. pauropelor, C. tasmaniana and C. tryjanowskii). It has a disjunct continental distribution represented in the Neotropical, Afrotropical and Australasian regions. The Cophinaria group (C. aculeata sp. nov., C. brachyrostrum, C. chiloensis, C. cophinaria, C. jethurmerae, C. lyrata, C. macfadyeni sp. nov., C. marlenae, C. pyemaireneri, C. ramus, C. rothschildi, C. valdivia sp. nov. and C. wallworki sp. nov.) has a similar distribution to the Capistrata group. The Afrotropical region has lowest diversity (two species-groups, six

A New Species

In this paper we describe and illustrate Zercon hamaricus sp. nov. based on all postembryonic stages obtained from soil samples and laboratory cultures. The new species belongs to a species group in which dorsal setae J1–J4 in females are short and similar in length, and J5 are considerably longer. In most species of this group opisthonotal setae J5 and Z4 are clearly displaced anteriorly. Zercon hamaricus sp. nov. is most similar to Z. forsslundi Sellnick, 1958 and to a less extent to Z. polonicus Błaszak, 1970. The females of Z. forsslundi, Z. polonicus and Z. hamaricus sp. nov. can be distinguished based on the range of J5, the length and character of the Z and S-series setae, the distance between setae Z5 and the location of gdZ3. We also include comparative information on other related species of Zercon. The new species is one of the six known species that have clearly visible sexual dimorphism in opisthonotal chaetotaxy.

Antennular Peduncle

McLaughlin & Haig (1984) divided the genus Pagurixus Melin, 1939 in two informal species groups on the basis of the presence or absence of setal row(s) on the ventral surface of the ultimate segment of the antennular peduncle. The first group, characterized by the presence of the setal rows, is herein named the P. boninensis species group, and the second, characterized by the absence of setal rows, is named the P. anceps group. In this paper, species of the P. boninensis group are reviewed. Thirteen species are recognized in this species group, of which six are new: Pagurixus laevimanus (Ortmann, 1892), P. maorus (Nobili, 1906), P. boninensis (Melin, 1939), P. tweediei (Forest, 1956), P. festinus McLaughlin & Haig, 1984, P. nomurai Komai & Asakura, 1995, P. pulcher Osawa, Fujita & Okuno, 2006, P. brachydactylus n. sp. , P. carinimanus n. sp. , P. concolor n. sp. , P. paulayi n. sp. , P. pseliophorus n. sp.  and P. ruber n. sp.  These species are further arranged into two subgroups based on the presence or absence of a lateral ridge on the carpus of the left cheliped. The new species are fully described and illustrated. Redescriptions or updated descriptions and illustrations are given for each previously described species in order to facilitate comparisons. The affinities and important morphological variations of the species are discussed and their overall distributions are updated. Because of the sexual dimorphism exhibited by species of this genus, separate identification keys to males and females are presented.

We evaluate the monophyly and phylogenetic relationships of the Pristimantis leptolophus species group and describe its external morphology, osteology, and some myological characteristics. We also compare the P. leptolophus species group to other related species groups. The P. leptolophus group is not monophyletic due to the inclusion of P. acatallelus, formerly believed to be part of the P. devillei group. The revised P. leptolophus group is composed of nine named species and six unnamed species. Based on our results, we recognize a new species group, the P. boulengeri species group, composed of eight species, many of which were previously assigned to the P. lacrimosus species group.

A New Species

We describe a new species of Varanus similar to V. caudolineatus and V. gilleni but distinguishable from each of these taxa on genetic and morphological criteria. The three species are closely related and together constitute a species group within subgenus Odatria. The new species is restricted to the Pilbara region of Western Australia and appears to be sympatric with V. caudolineatus at several localities. It is more widely separated from known populations of V. gilleni. The new species is associated with mulga woodland and is at least partially arboreal, but little else is known of its ecology. Combined morphometric and meristic analyses indicate complex patterns of sexual dimorphism in all three species, including relative body elongation in females that is reflected in higher modal presacral vertebral counts in females than males of each species. Body elongation of females needs to be taken into account in future analyses of sexual dimorphism in varanid lizards.

Two new species of black flies, Simulium mainitense and S. tukurongense, are described from Palawan, the Philippines. Both species are placed in the Simulium nitidithorax subgroup of the Simulium tuberosum species-group of Simulium (Simulium). They are characterized by the female sensory vesicle of medium length, pupal thorax covered with round tubercles, and anterodorsal trichomes on the pupal thorax longer than frontal trichomes. This combination of characters separates these two new species from S. quasifrenum Delfinado, the only previously known member of the S. nitidithorax subgroup from Palawan, and nine other related species from Sabah, Sarawak, Peninsular Malaysia and India. Simulium mainitense sp. nov. is distinguished from S. tukurongense sp. nov. in the female by the somewhat larger body size, and greater length ratio of the labrum against the clypeus; and in the pupa by the much longer gill filaments.

Three new species of Anaulacomera are described, Anaulacomera (Anaulacomera) mariellae sp. n. and Anaulacomera (Anallomes) arlindoi sp. n., belonging respectively to the Inermis and Lanceolata species group, and Anaulacomera angelinae sp. n., placed as incertae sedis. The individuals were collected at the Iguaçu National Park and adjacent small fragments of Atlantic Forest, in southwestern Paraná state, Brazil. The description was based on external morphology of males. We also present distribution maps for the species of the Inermis and the Lanceolata species groups.

Tropical South America

The giant water bug fauna from tropical South America remains poorly known. Three species of Belostoma Latreille (Belostoma fittkaui De Carlo, B. sayagoi De Carlo and B. hirsutum Roback & Nieser) have been cited only a few times in the literature. These three species are remarkable since they represent an extreme variation for the genus, with article II of the labium distinctly shorter than article III. Here, the synonymy of B. hirsutum with B. sayagoi is proposed based on examination of type material and additional specimens. Further, B. fittkaui and B. sayagoi are redescribed, including discussion about comparative morphology with congeners. A new species group is proposed for these species and a key to the Belostoma species groups is provided. Distribution records are also updated.
