Neotropical ennomine moths: a review of the genera (Lepidoptera: Geometridae)

The classification of the Neotropical genera of the Ennominae is reviewed and 267 genera are recognised to occur in this region. Three new genera are described and three others are reinstated, while 48 generic synonyms are newly established. Other changes established in this work include 14 species synonyms and 237 new or reinstated combinations. External features and genitalia of representative members of the genera are illustrated (753 figures). All the known Neotropical species and subspecies of Ennominae are listed ( c . 3470), plus their synonyms. The tribes to which the genera belong are assessed, with c . 200 of the genera assigned to tribe or other suprageneric grouping.  © 2002 The Linnean Society of London, Zoological Journal of the Linnean Society , 2002, 135 , 121–401.     

Exploring phenotypic plasticity and biogeography in emerald moths: A phylogeny of the genus Nemoria (Lepidoptera: Geometridae)

The moth genus Nemoria (Lepidoptera: Geometridae) includes 134 described species whose larvae and adults display a considerable range of phenotypic plasticity in coloration and morphology. We reconstructed the phylogeny of 54 species of Nemoria and seven outgroups using characters from the mitochondrial genes, Cytochrome Oxidase I and II (COI and COII), and the nuclear gene, Elongation Factor-alpha (EF-1alpha). Maximum parsimony, maximum likelihood and Bayesian inference were used to infer the phylogeny. The 54 ingroup species represented 13 of the 15 recognized species groups of Nemoria [Ferguson, D.C., 1985. Fasc. 18.1, Geometroidea: Geometridae (in part). In: Dominick, R.B. (Ed.), The Moths of America North of Mexico, Fasc. 18.1. Wedge Entomological Research Foundation, Washington; Pitkin, L.M., 1993. Neotropical emerald moths of the genera Nemoria, Lissochlora and Chavarriella, with particular reference to the species of Costa Rica (Lepidoptera: Geometridae, Geometrinae). Bull. Br. Mus. Nat. Hist. 62, 39-159], and the seven outgroups came from four tribes of Geometrinae. These data support Nemoria as a monophyletic group and largely recover the species groupings proposed in previous taxonomic analyses using morphological characters. Phenotypic plasticity of larvae is not correlated with plasticity of adults among those species of Nemoria where life histories are known, and appears to be evolutionarily labile for both life history stages: Species exhibiting larval phenotypic plasticity, such as N. arizonaria and N. outina, are placed in several distinct clades, suggesting that this trait has evolved multiple times, and species displaying adult phenotypic plasticity are likewise distributed throughout the phylogeny. A comparative analysis of the biogeographic history of Nemoria supports a South American origin for the genus with multiple introductions into North America, and an application of published substitution rates to the phylogram provides an age estimate of 7.5 million years.     

Hidden generic diversity in Neotropical birds: molecular and anatomical data support a new genus for the "Scytalopus"indigoticus species-group (Aves: Rhinocryptidae)

The genus Scytalopus is a species-rich and taxonomically complicated component of the Neotropical avian family Rhinocryptidae. Probably because Scytalopus is a superficially uniform assemblage, its monophyly has not been seriously questioned. We investigated phylogenetic relationships of a representative set of species in the genus using nuclear and mitochondrial DNA sequences as well as anatomical data, and provided the first test of its presumed monophyly by including in the analyses its hypothesized closest relatives (the genera Myornis, Eugralla, and Merulaxis) as well as most rhinocryptid genera. We found strong support for the paraphyly of the genus Scytalopus, with the Scytalopus indigoticus species-group forming a clade with Merulaxis. A well-supported clade including the genera Eugralla, Myornis, and the remaining Scytalopus was also recovered. Because these results were recovered independently and with strong support using mitochondrial and nuclear data, and were entirely consistent with anatomical data, we erect a new genus for the S.indigoticus species-group. These findings illustrate the importance of formally testing hypotheses of monophyly even for well-accepted groups of Neotropical birds.     

Revision of the Nearctic species of the genus Stiropius Cameron (=Bucculatriplex Auct.) with the description of a new related genus (Hymenoptera: Braconidae)

Abstract. The New World rogadine genus Stiropius Cameron is revised for the Nearctic region and a new related genus from the Americas, Viridipyge , is decribed. Bucculatriplex Viereck is found to be a junior subjective synonym of Stiropius Cameron. Three Nearctic species are recognized: S.bucculatricis (Ashmead) comb.n., S.californicus sp.n. and S.wagneri sp.n. A single Nearctic specis of Viridipyge is described as new: V.prunicola , and a Neotropical species, V.letifer (Mann) comb.n., is found to be congeneric. The biology and systematic relationships of both genera are discussed; the two genera appear to represent a relatively basal branch of the Rogadini lineage.     

PETAURALGES MORDAX SP. N. (ACARI: PSOROPTIDAE) FROM AN AUSTRALIAN DASYURID MARSUPIAL

Abstract
Petauralges mordax sp. n. from Phascogale tapoatafa (Meyer) is the second species of this listropsoralgine genus to be recorded from Australia. The other genera in the subfamily are Neotropical.     

A revision of the tribe Plectrothripini of fungus-feeding Thysanoptera (Phlaeothripidae: Phlaeothripinae)

Abstract The tribe Plectrothripini is redefined with examination of its systematic relationships. Keys are provided to the ten genera and forty-seven species in this tribe; one genus and eighteen species are newly described; one genus and two species are newly synonymized; two genera, Chiridothrips and Eurytrichothrips , are here removed from this tribe. The species of the tribe occur throughout the tropical and subtropical regions of the world; seventeen species are recorded from the Oriental Region, seventeen species from the Neotropical Region, ten species from the Afrotropical Region, two from Australia and one from the Pacific. They seem to be fungus-feeders, being found mainly under the bark of trees or on dead branches.     

Mariapanteles (Hymenoptera, Braconidae), a new genus of Neotropical microgastrine parasitoid wasp discovered through biodiversity inventory

A new genus of microgastrine parasitoid wasps, Mariapanteles Whitfield & Fernández-Triana, gen. n., is described from rain forests of the Neotropics. The new genus is related to the common and speciose genus Pseudapanteles, but can be distinguished from the latter by having a complete transverse carina on the propodeum which forks around the spiracles. A molecular analysis based on data from COI from specimens of the proposed new genus plus possibly related genera confirms its generic distinctness. A key to two known species, Mariapanteles felipei Whitfield, sp. n. (Costa Rica) and Mariapanteles dapkeyae Fernández-Triana, sp. n. (Brazil) is provided. Evidence from collections suggests that there are other undescribed Neotropical congenerics. Specimens of Mariapanteles were likely confused in the past with the genus Beyarslania (referred to as Xenogaster until recently) but present information suggests that Beyarslania is restricted to the Afrotropical region while the Neotropical species clearly belong to a different genus, which we propose as new.     

Six New Species of Dobsonflies from Venezuela (Megaloptera: Corydalidae: Corydalinae)

Six new species of dobsonflies (Megaloptera: Corydalidae: Corydalinae) from Venezuela are described and illustrated, two in the Neotropical genus Chloronia and four within the New World genus Corydalus. Chloronia contains 15 previously described species. The new species Chloronia gaianii and C. marthae, each from the southern tepui and Andean regions, appear to be most closely related to C. hieroglyphica (Rambur) and C. mirifica Navás, respectively. Corydalus contains 30 previously described species. The new species Corydalus clavijoi, of Andean affinity, appears most closely related to C. tesselatus Stitz; C. crossi, from Auyán-tepuí, might be closely related to C. nubilus Erichson; and both C. hayashii and C. mayri, from westernmost Guayana Shield area and Aracamuni tepuis, respectively, clearly belong in the distinct and monophyletic C. arpi Navás species group. Keys for identification of the Venezuelan species of both genera are provided.     

The planthopper family Achilixiidae (Homoptera, Fulgoroidea): a synopsis with a revision of the genus Achilixius

Abstract The planthopper family Achilixiidae (Homoptera, Auchenorrhyncha, Fulgoroidea) is reviewed and the Oriental genus Achilixius Muir revised. As here defined, the family consists of two genera: Bobaiotes Muir ( Muirilixius Metcalf is here made a junior synonym, syn.n.) from the Neotropical region and Achilixius from the Oriental region. Sixteen Achilixius species are described or redescribed from Philippines, Sabah and Sulawesi. Females of undescribed species are also reported from the Solomon Islands and New Guinea. The following new species of Achilixius are described: Bakeri, irigae and mayoyae from the Philippines: fennahi and muiri from Sabah; minahassae, danaumoati, torautensis, fasciata, kolintangi, muajati and morowali from Sulawesi. A key to males is given. The following new combinations are established: Bebaiotes banksi (Metcalf), B.guianesus (Fennah) and B.nigrigaster Muir restored to its original combination, comb.rev. The relationship of Achilixiidae to other fulgoroid families is discussed.     

Morphological discordance of the new trypanosomatid species phylogenetically associated with the genus crithidia

Three new species of monoxenous parasites from the Neotropical Heteroptera are described on the basis of the ultrastructure of cells in culture, as well as gene sequences of Spliced Leader (SL) RNA, glyceraldehyde phosphate dehydrogenase (GAPDH) and small subunit (SSU) rRNA. The results have highlighted a striking discrepancy between the morphological (dis)similarities and the phylogenetic affinities among the insect trypanosomatids. Although each of the new species is characterized by a distinct set of morphological characters, based on the predominant promastigotes observed in culture, each of them has been provisionally assigned to the genus Leptomonas pending the future revision of this genus. Yet, instead of the phylogenetic affinity with the other members of this polyphyletic genus, the new species are most closely related to Crithidia species. Thus, the extremely long promastigotes of Leptomonas acus sp. n. and the unique morphological features found in Leptomonas bifurcata sp. n. sharply contrast with their respective relatives C. fasciculata and C. deanei both of which are typical choanomastigotes. The results clearly show that the current classification at the genus level is misleading and needs to be revised. The phylogenetic clades potentially representing the candidate new genera of monoxenous trypanosomatids have started to emerge from the presented analyses.     

Historical biogeography and diversification within the Neotropical parrot genus Pionopsitta (Aves: Psittacidae)

Aim We investigate spatial and temporal patterns of diversification within the Neotropical avifauna using the phylogenetic history of parrots traditionally belonging to the genus Pionopsitta Bonaparte 1854. This genus has long been of interest for those studying Neotropical biogeography and diversity, as it encompasses species that occur in most Neotropical forest areas of endemism. Location The Neotropical lowland forests in South and Central America. Methods Phylogenetic relationships were investigated for all species of the genus Pionopsitta and five other short‐tailed parrot genera using complete sequences of the mitochondrial genes cyt b and ND2 as well as 26 plumage characters. The resulting phylogeny was used to test the monophyly of the genus, investigate species limits, and as a framework for reconstructing their historical biogeography and patterns of diversification. Results We found that the genus Pionopsitta, as previously defined, is not monophyletic and thus the Chocó, Central American and Amazonian species will now have to be placed in the genus Gypopsitta. The molecular and morphological phylogenies are largely congruent, but disagree on the position of one of the Amazon basin taxa. Using molecular sequence data, we estimate that species within Gypopsitta diversified between 8.7 and 0.6 Ma, with the main divergences occurring between 3.3 and 6.4 Ma. These temporal results are compared to other taxa showing similar vicariance patterns. Main conclusions The results suggest that diversification in Gypopsitta was influenced mainly by geotectonic events, marine transgressions and river dynamics, whereas Quaternary glacial cycles of forest change seem to have played a minor role in the origination of the currently recognized species.     

Molecular phylogenetics and biogeography of Neotropical piping guans (Aves: Galliformes): Pipile Bonaparte, 1856 is synonym of Aburria Reichenbach, 1853

The Cracidae are Neotropical galliform birds with 11 genera currently recognized. To investigate the questioned validity of Pipile Bonaparte, 1856 and the monotypic Aburria Reichenbach, 1853 as separate genera, we gathered data from 2727 bp of mitochondrial DNA (cytochrome b, ND2 and control region) and 151 osteological characters. Our phylogenetic analyses of DNA sequences indicated that Aburria aburri is embedded within Pipile. Also, genetic distances between Aburria and any Pipile species are equivalent to the distances estimated for other congeneric cracid species, which genus status is not doubtful. Although the osteological characters do not have phylogenetic signal to solve the phylogenetic relationships at species level, five synapomorphies were found for Aburria and Pipile. Therefore, we suggest that Pipile should be merged with Aburria, which is the oldest described genus. We estimated that speciation in this group occurred in the Plio-Pleistocene, concordant with other birds, primates and rodents that have similar geographic distribution, and proposed a diversification hypothesis based on the occurrence of sea transgressions and the formation of the Amazon Lagoon. Therefore, we conclude that these palaeogeographic events may have contributed to Neotropical taxa diversification to a greater extent than previously suspected.     

Geometric morphometrics of the skull of Tinamidae (Aves, Palaeognathae)

The Tinamidae comprise exclusively Neotropical palaegnathous birds, with homogeneous body morphology and no sexual dimorphism. The goal of this work was to explore the variation in skull morphology between taxa and its possible correspondence with features such as diet or gender using geometric morphometric tools. Eleven landmarks were analyzed in 53 skulls of 4 genera that inhabit grasslands: Nothoprocta, Eudromia, Nothura and Rhynchotus. Intrageneric and intergeneric variability was analyzed. The genera studied here can be distinguished based on the geometric shape of their skull, with prenarial region length and neurocranium shape as the most outstanding features. In the genus Eudromia, males and females could be differentiated, while in the genus Nothoprocta, the species differentiated according to their trophic habits. This study allows establishing that genera and, in some cases, the gender of the Tinamidae can be differentiated based on cranial shape.     

Revision of the Neotropical ant subfamily Leptanilloidinae

Abstract. The rare Neotropical ant subfamily Leptanilloidinae is revised and its internal phylogeny and biogeography discussed. A new genus, Asphinctanilloides gen.n., including three new species, A. amazona, A. anae and A. manauara, and three new species of Leptanilloides , L. improvisa, L. legionaria and L. sculpturata are described. The only previously known species of the subfamily, L . biconstricta Mann (1923) , is redescribed, and the larva of L. legionaria sp.n. is described. Keys to the genera and the species, and a phylogeny of the group are provided. Emphasis has been placed on the study of abdominal and sting characters.     

Arberella (Poaceae: Bambusoideae): A new genus from tropical America

Arberella, a new genus of bambusoid grasses, is established, based on the newly described species,A. dressiert. Also belonging to this new genus are the taxa originally namedOlyra flaccida andRaddia costa-ricensis and several new species from Panama and Brazil which will be described later. The new genus is presented in a key to the genera of the tribe Olyreae, of which it is a member, and a key is given to the three species treated in this paper.     

Pugs of the tribe Eupitheciini (Lepidoptera,Geometridae): the history of study and distribution over biogeographic regions

The World fauna of the tribe Eupitheciini is the most species-rich in the family Geometridae. This tribe includes about 1900 species (almost 3000 species-group names) from 47 genera; about one third of the genera (15) are monotypic. The generic diversity of Eupitheciini is the highest in the Australian (38 genera, 11 of them endemic) and Oriental regions (32 genera, 4 endemic) and the lowest in the Neotropical Region (possibly one genus only). The faunas of different biogeographic regions can be arranged in following order by their species richness: the Palaearctic (487 species), Oriental (397), Neotropical (346), Australian (251), Afrotropical (198), and Nearctic Regions (166 species). Eupithecia is the most species-rich genus in the family Geometridae and the entire order Lepidoptera, and one of the largest genera in the whole World fauna of insects. The greatest number of species of this genus is recorded in the Palaearctic Region (466 species), where Eupithecia accounts for about 95% of the tribe Eupitheciini. The mainland of the Oriental Region (especially the Himalayas) is also very species-rich; however the proportion of the Eupithecia representatives decreases towards Malaysia, Sundaland, and the Australian Region (about 2% of the tribe). The Eupitheciini faunas have the greatest similarity at the generic level between the Oriental and Australian Regions (the Jaccard and Sørensen coefficient values being 0.62 and 0.77, respectively). The Palaearctic fauna is more similar to the Afrotropical and Oriental faunas at the genus-group level. On the whole, the fauna of the Nearctic Region is similar to that the West Palaearctic, with the exception of the fact that representatives of the genera Gymnoscelis and Chloroclystis are absent in North America, although two endemic genera Nasusina and Prorella are present. At the genus-group level, the Nearctic fauna of Eupitheciini is more similar to the Neotropical (the Jaccard and Sørensen coefficients 0.20 and 0.33, respectively) than to the Palaearctic fauna (0.17 and 0.29). The number of synonymies is very high in the tribe Eupitheciini because of the homogeneity of this group, whose species are difficult to identify without the use of elaborate anatomical techniques. Modern revisions, catalogues, surveys, and atlases on Eupitheciini are absent for many countries and large geographic regions. Revisions of pugs of the tribe Eupitheciini for some biogeographic regions are extremely difficult because of fragmentation of entomological collections including the type specimens of many species-group taxa. A large fraction of synonyms is characteristic of parts of the World with the best known faunas: Europe (64% of synonyms) and North America (39%). On the contrary, the lowest levels of synonymy are typical of the less known faunas of the regions situated at the equatorial latitudes, namely the Neotropical (9%) and Afrotropical (8%) ones.
