Abstract Prodidominae was recently re-established as a subfamily of Gnaphosidae, comprising 316 species placed in 33 genera. In this study, we conduct a cladistic analysis including 59 species of Prodidominae and 32 outgroup species. The matrix is composed of 291 morphological characters and the data are analysed under the parsimony criterion, using differing weighting regimes. Prodidominae is not recovered as monophyletic, because Anagrina did not arise within the subfamily. Cryptotoerithus, Molycria, Myandra, Nomindra, Wesmaldra and Wydundra arise to form a clade. Thus, we re-establish Molycriinae as a distinct subfamily in Gnaphosidae, sister to Prodidominae. We redefine the limits of Prodidominae to include the genera Austrodomus, Brasilomma, Caudalia, Chileomma, Chileuma, Chilongius, Eleleis, Indiani, Katumbea, Lygromma, Lygrommatoides, Moreno, Namundra, Neozimiris, Nopyllus, Paracymbiomma, Plutonodomus, Prodidomus, Purcelliana, Theuma, Theumella, Tivodrassus, Tricongius, Zimirina and Zimiris. Species of these genera share the presence of anterior lateral spinnerets with pyriform gland spigots associated with patches of long setae and the presence of a large protrusion between coxae IV with erect setae and unsclerotized margins. In addition, we propose three new synonymies: Oltacloea as a junior synonym of Tricongius, and Prodida as junior synonym of Prodidomus. Lygromma ybyguara is transferred to Tricongius.

AbstractA hypothesis of the phylogeny of the tribes of Dytiscinae is presented based on a cladistic analysis of adult morphological characters. All tribes of Dytiscinae were included with larger tribes represented by multiple genera. Outgroups included members of all major lineages (subfamilies) of Dytiscidae. The matrix consists of 22 taxa and 45 characters. A single most parsimonious cladogram was produced by the analysis. It is concluded from the analysis that Dytiscinae is paraphyletic with respect to the genus Notaticus Zimmermann which has been previously recognized as the only member of the subfamily Aubehydrinae. Its position within the subfamily requires that it be placed within its own tribe, Aubehydrini. Additionally, Dytiscini was found to be paraphyletic, and a new tribe, Hyderodini, is proposed to contain the genus Hyderodes Sharp. Dytiscini is restricted to include only the genus Dytiscus Linneaus. Dytiscinae and all other tribes within the subfamily were found to be monophyletic. The proposed relationships of the tribes of Dytiscinae are Cybistrini + (Dytiscini + (Hyderodini + (Aubehydrini + (Hydaticini + (Eretini + Aciliini))))). Characters discovered to be useful for phylogenetic analysis of the subfamily are illustrated and described. The tribes are diagnosed and a key is presented for distinguishing them.

Rhabdepyris (Epyrinae) is a cosmopolitan genus comprised of 132 species. No morphological synapomorphies are known for the genus and the genus is characterized by a combination of characters common to most Epyrini. Herein, we performed a cladistic analysis based on morphological characters to test the monophyly of Rhabdepyris. The three known subgenera of Rhabdepyris (Chlorepyris, Rhabdepyris s. str., and Trichotepyris) and other Epyrini (Anisepyris, Bakeriella, Calyozina, Epyris, Laelius, Trachepyris) were included in the ingroup. The cladistic analysis of 48 taxa (46 ingroup species and two outgroup species) and 81 structural characters yielded 72 cladograms under equal weights, and one under successive weighting. Rhabdepyris was found to be polyphyletic; the subgenus Trichotepyris was closely related to Anisepyris whereas Rhabdepyris str. s. was closely related to Laelius. The subgenus Chlorepyris is paraphyletic. Morphological characters are discussed in the light of the new phylogeny; novel characters are proposed and illustrated, and a new classification of Rhabdepyris and Epyrini is proposed. The following nomenclatural changes are proposed: Trichotepyris is synonymized under Anisepyris (syn. n.); Chlorepyris is recognized as a separated genus (stat. rev.); all 12 American species of the subgenus Rhabdepyris are transferred to Laelius; 22 species of Trichotepyris are transferred to Anisepyris; 58 species are transferred to Chlorepyris. A remaining total of 40 species are now recognized in Rhabdepyris. The holotype of Rhabdepyris, R. myrmecophilus Kieffer, the type species of Rhabdepyris, is redescribed.

AbstractCollucci, E. & Sallum, M. A. M.: Phylogenetic analysis of the subgenus Kerteszia of Anopheles (Diptera: Culicidae: Anophelinae) based on morphological characters. Insect Syst. Evol. 34: 361-372. Copenhagen, December 2003. ISSN 1399-560X. A phylogenetic analysis was carried out for 12 species of Anopheles (Kerteszia) Theobald with Anopheles (Nyssorhynchus) oswaldoi (Peryassü), An. (Stethomyia) kompi Edwards and An. (Lophopodomyia) squamifemur Antunes as outgroup species. Sixty-six characters were coded from the external morphology of the adult male, adult female, fourth-instar larva and pupa, and analyzed under the parsimony criterion using PAUP. The results confirm that Kerteszia, and the clade Kerteszia + Nyssorhynchus, are both monophyletic. Bootstrap support was ≥ 50% for all internal nodes, except for the (An. bellator + An. homunculus) clade which was < 50%. The results of this study allow a confident estimate of the relationships of species within Kerteszia.

Chelodesmidae is one of the most diverse families belonging to the Polydesmida, comprising almost 800 described species distributed in 172 genera, 20 tribes and two subfamilies. Among the tribes within the Neotropical subfamily Chelodesminae, Arthrosolaenomeridini represents a very interesting group occurring in the Central-West region of Brazil. Currently the tribe contains three genera: Arthrosolaenomeris Schubart, 1943, Gangugia Schubart, 1947, and Angelodesmus Schubart, 1962. In this study, we conducted a cladistic analysis including 18 species of Arthrosolaenomeridini and 7 species of other associated Chelodesminae tribes as an outgroup. The matrix is composed of 64 morphological characters from which 39 are herein proposed for the first time. The data were analyzed under the parsimony criterion using TNT 1.5. Based on the results, Arthrosolaenomeridini was recovered as monophyletic with Macrocoxodesmini + Telonychopodini as sister group. Arthrosolaenomeris Schubart, 1943 and Gangugia Schubart, 1947 were recovered as monophyletics. The genus Angelodesmus Schubart, 1962 was recovered as paraphyletic and redefined as monotypic. The tribe is now composed of the genera Arthrosolaenomeris (6 spp.), Gangugia (6 spp.), Angelodesmus (monotypic), Abiliodesmus n. gen. (4 spp.) and Folcloredesmus n. gen. (monotypic). In addition, we conduct a taxonomic revision of the tribe Arthrosolaenomeridini providing detailed redescriptions, drawings, and distribution maps for all species and genera, including the two new genera and the ten new species proposed: Arthrosolaenomeris saci n. sp.; A. curupira n. sp.; A. caipora n. sp.; A. iara n. sp.; Gangugia boitata n. sp.; G. cuca n. sp.; G. boto n. sp.; G. mula n. sp.; Abiliodesmus mapinguari n. sp. and Folcloredesmus thomasi n. sp. Furthermore, we include an identification key to all the genera and species.

New Oriental taxa of the Lygistorrhinidae - Blagorrhina gen. n., with B. blagoderovi sp. n. and B. brevicornis sp. n.; Gracilorrhina gracilis gen. n., sp. n.; and Labellorrhina gen. n., with L. grimaldii sp. n. and L. quantula sp. n. are described, and two undescribed species, known only from females, are characterized. Based on this new material, the family is redefined. The phylogeneticrelationships among the taxa of Lygistorrhinidae were studied by parsimony analysis using 43 morphological characters from the adults of 25 ingroup and one outgroup species. The cladistic analysis produced 14 most parsimonious cladograms. The solution obtained suggests unambiguously the following phylogeny: Palaeognoriste Meunier and “Lygistorrhina” asiatica Senior-White are successively sister groups of the rest of the Lygistorrhinidae; there is a clade Labellorrhina + (Gracil- orrhina + (Blagorrhina + ((Seguyola Matile + (Loyugesa Grimaldi & Blagoderov + Matileola Papp))))) with a monophyletic Lygistorrhina Skuse – Probolaeus Williston lineage as sister group. The phylogeny among the latter group remains largely unresolved.

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 &amp; Yeates, gen. nov., Dissodesma Bowden &amp; Li, gen. nov., Nigromyia Li &amp; Yeates, gen. nov. and Robertsmyia Li &amp; Yeates, gen. nov. Ten new species are described: Dissodesma immaculata Li &amp; Yeates, sp. nov., Dissodesma flava Li &amp; Yeates, sp. nov., Dissodesma smarti Li &amp; Yeates, sp. nov., Nigromyia collessi Li &amp; Yeates, sp. nov., Nigromyia crocea Li &amp; Yeates, sp. nov., Nigromyia flavimana Li &amp; Yeates, sp. nov., Nigromyia longistriata Li &amp; Yeates, sp. nov., Nigromyia pantherina Li &amp; Yeates, sp. nov., Nigromyia parva Li &amp; Yeates, sp. nov. and Nigromyia tomentosa Li &amp; 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

Evolutionary Story

Abstract Holopothrips is a diverse group of thrips associated to galls in the Neotropics, with a variety of host plants and wide morphological diversity. Relationships to other Neotropical groups have been proposed, but are still untested, and the monophyly of the genus remains doubtful. Here, we perform a phylogenetic analysis of Holopothrips, based on morphological characters. A total of 87 species were included in the matrix and eight analyses were carried out, but all of them failed to recover Holopothrips as a monophyletic grouping. Bremer and Bootstrap support values were low, and the topologies varied among all analyses, with uncertain internal relations for the ingroup. These results indicate that the relationships for Holopothrips species, and the proposed related genera, are more complex than previously reported; and morphological characters may not be enough to recover the evolutionary story within this group. We also discuss the influences of different character coding, continuous characters and weighting schemes in our results.

Preliminary Phylogenetic Analysis

AbstractThe subgenus M. (Scaphigenia) Lacordaire includes six species distributed in arid regions of South America. A systematic revision of this subgenus is presented, including re-descriptions and an update of distribution data of the six species. A preliminary cladistic analysis is performed to test the relationships among the species of the subgenus and if the morphological characters used are suitable. A key is presented to separate the seven subgenera of Megalostomis Chevrolat as well as a key for the species of the subgenus M. (Scaphigenia). Male aedeagus internal sac of the nine studied taxa are described and illustrated. This constitutes the first internal sac descriptions for members of this subtribe and could help clarify the homology of such structures within Cryptocephalinae. M. (S) consimilis Achard is reassigned to the species status on the base of genitalic characters. The cladistic analysis was done using forty-one characters from adult external morphology and male and female genitalia. Two species of two different subgenera of Megalostomis: M. (Megalostomis), and M. (Heterostomis) Lacordaire, and one representative of the genus Themesia Lacordaire were selected as out groups. Results were obtained by implicit enumeration using parsimony software. Three equally parsimonious trees were obtained of 45 steps, Ri=0.952, and Ci= 0.941. Support of each group was evaluated by Jacknifing, Bootstrap and Bremer values. Relationships between species are discussed.

Morphological characters of adults of the treehopper subfamily Nicomiinae Haupt, 1929 (Hemiptera, Membracidae) including seven genera (Eudonica gen. nov.; Euwalkeria Goding, 1926; Holdgatiella Evans, 1962; Nicomia Stål, 1858; Nodonica Dietrich, McKamey& Deitz, 2001; Stalomia gen. nov.; and Tolania Stål, 1858) and 22 species (16 new) are described and illustrated. Keys are provided for genera and for species of Euwalkeria, Holdgatiella, and Nicomia. Nomenclatural changes, based on study of the primary type material of 15 species, include three new combinations, one new synonymy, and reinstatement of one junior synonym. Eudonica has one species, Eudonica nanella sp. nov.; Euwalkeria has five species, including four new species: E. colorata sp. nov., E. distincta sp. nov., E. perdita sp. nov., E. rubrica sp. nov.; Holdgatiella has two species, one of which is described as new: Holdgatiella chiloensis sp. nov.; Nicomia has twelve species, nine of which are described as new: N. buccina sp. nov., N. harenosa sp. nov., N. inscripta sp. nov., N. jucunda sp. nov., N. monticola sp. nov., N. nigrifasciata sp. nov., N. notidana sp. nov., N. pulchella sp. nov., N. serrata sp. nov.; Nodonica has one species, Nodonica bispinigera Dietrich, McKamey & Deitz; and Stalomia has one species, Stalomia veruta sp. nov. Tolania contains eleven previously described species and nearly 60 new species, which will be treated in a later publication. Three new combinations are proposed: one species described in Nicomia is placed in the tribe Abelini (Centrotinae) as Abelus retrospinosus (Lethierry) comb. nov.; one species previously placed in Nicomia is transferred to the genus Tolania as T. obliqua (Walker, 1858), comb. nov.; one species described in Holdgatiella is placed in the genus Tolania as T. stria (Cryan & Deitz, 2002), comb. nov. One new synonymy is proposed: Hoplophera [sic] cicadoides Walker, 1862, syn. nov., a junior synonym of Nicomia interrupta Stål, 1858. Nicomia subfasciata Stål, 1858, is reinstated. The results of a phylogenetic analysis based on morphology are presented, illustrating the hypothesized relationships among species and genera of Nicomiinae. The analysis supports the broader concept of Nicomiinae proposed here. The monophyly of this group is supported by eleven characters, and all of the included genera are also monophyletic.
