The present paper presents a cladistic analysis of the spider genus Tobias Simon, 1895. The analyses were based on a matrix with 29 terminal taxa scored for 86 morphological characters, with a dataset tested under two methodologies for character weighting (i.e. equal and implied weighting). Both analyses supported the paraphyletic relationship of Tobias with Epicadus Simon, 1895, with the former considered a junior synonym of the latter (new synonymy). Onocolus, Epicadinus and Epicadus form a clade supported by two synapomorphies, corroborating previous taxonomic assumptions regarding the proximity of these genera. Epicadus has two lineages: the ‘pustulosus clade’, comprising bark-like individuals that camouflage themselves on tree trunks and branches, and the ‘heterogaster clade’, which consists of a group of spiders that present a wide range of polychromatism and use flowers as hunting sites. Synonymies are presented and a new combination for all species previously assigned as part of Tobias is proposed. Epicadus now comprises nine species.

With the purpose of promoting nomenclatural stability, this paper addresses a number of errors, omissions, and controversial conclusions in a recent revision of the green lacewing genus Ceraeochrysa by Freitas et al. (2009). 1. Valid species, new combinations and synonymies: (a) We identified Ceraeochrysa chiricahuae Freitas and Penny (in Freitas et al. 2009), Chrysopa forreri Navás, and Chrysopa intacta Navás as subjective synonyms. Thus, Ceraeochrysa intacta, a species that was previously synonymized under Ceraeochrysa placita (Banks), becomes the valid name of the species [New status, new combination]. Chrysopa forreri is now synonymized under Cer. intacta, not Cer. placita [New synonymy]. And, Cer. chiricahuae becomes a junior synonym of Cer. intacta, not a valid species of Ceraeochrysa [New synonymy]. (b) We enumerate specific internal and external features of the Chrysopa cornuta Navás type that identify it as conspecific with Ceraeochrysa caligata (Banks), not Ceraeochrysa cincta (Schneider) as proposed by Freitas et al. (2009). Thus, Ceraeochrysa cornuta (Navás), which has priority, is reinstated as the valid name [Reinstated status, reinstated combination], and Ceraeochrysa caligata (Banks) is reinstated as a junior subjective synonym of Cer. cornuta, not a valid species [Reinstated synonymy]. (c) We provide documented evidence for reinstating three synonymies that Freitas et al. had reversed [Reinstated synonymies]: (i) Allochrysa parvula Banks is a junior subjective synonym of Ceraeochrysa lineaticornis (Fitch); (ii) Chrysopa columbiana Banks is a junior subjective synonym of Ceraeochrysa lineaticornis (Fitch); (iii) Chrysopa rochina (Navás) is a junior subjective synonym of Ceraeochrysa cincta (Schneider). 2. Generic assignments: (a) Visual evidence is provided for the placement of Ceraeochrysa laufferi (Navás) in Ungla. Therefore, Ungla laufferi (Navás) is reinstated as the valid name [Reinstated combination]. (b) We question Freitas et al.’s rationale for including Cer. placita (Banks) and Cer. intacta (Navás) (as Cer. chiricahuae Freitas and Penny) in the genus Ceraeochrysa; female and larval features of the two species differ markedly from those used to characterize Ceraeochrysa species. As an alternative that recognizes the uncertainty surrounding the generic placement of these species and that avoids additional, unnecessary name changes, we propose including the caveat “genus incertae sedis” with the names, as follows: Ceraeochrysa placita (Banks), genus incertae sedis, and Ceraeochrysa intacta (Navás), genus incertae sedis. 3. Type designations: (a) Errors concerning the Chrysopa furculata Navás type in the Muséum national d’Histoire naturelle, Paris (MNHN), are corrected, and doubts raised by Freitas et al. (2009) concerning the identification of this specimen as the holotype are removed. (b) The earlier designation of the Chrysopa rochina (Navás) type in the MNHN as the lectotype (not holotype) is verified.

The monobasic genus Caenoteleia Kieffer (Hymenoptera: Platygastridae) is considered to be a junior synonym of the widespread and common genus Calliscelio Ashmead, new synonymy. Calliscelio elegans (Perkins) is redescribed, transferred to Calliscelio, new combination, and its geographic distribution documented. Originally described from Hawai‘i, this species is widespread through the tropics. The species likely is distributed by human commerce, possibly in association with cricket pests (Orthoptera: Gryllidae) of sugar cane.

AbstractIn this study Parorphula is re-described based on characters from the external morphology and genitalia. This genus comprised two species: P. pallidinota and P. latipennis, that were described based mostly on characters from external morphology. The morphological analysis conducted in this study plus the support of results from a cladistic analysis showed that external morphological characters justify the creation of a new genus for P. latipennis. Therefore, the genus Neorphula is proposed and the new combination is established.

AbstractThe phylogeny of the Hydroporinae is investigated in a cladistic analysis emphasizing placement of the genus Peschetius Guignot, historically placed in the tribe Hydroporini. Sixty-nine adult and larval morphological characters were coded for 61 species of Hydroporinae representing eight of the nine tribes. Cladistic analysis of the data resulted in 396 most parsimonious cladograms (length = 176, CI = 46, RI = 80). The results indicate that the genus Peschetius is the sister group to the tribe Bidessini based mainly on an unambiguous character, the presence of a prominent internal spermathecal spine, and several other more ambiguous or homoplasious characters. The tribe Bidessini is expanded to include the genus Peschetius, and it is formally transferred from the tribe Hydroporini. Other results indicating interesting relationships of tribes and genera within Hydroporinae are also discussed. Results include; 1) a dramatically paraphyletic Hydroporini with Laccornellus Roughley and Wolfe, Canthyporus Zimmermann and Hydrocolus Roughley and Larson in basal positions within the phylogeny, 2) Hydrovatus Motschulsky and Queda Sharp resolved as sister groups and not closely related to Methlini van den Branden, 3) support for close relationship of Pachydrus Sharp (Pachydrini Biström, Nilsson and Wewalka) with Hyphydrini Sharp, 4) paraphyly of Hygrotus Stephens sensu lato with the relationship H. (Coelambus) Thomson + (Hygrotus sensus stricto + Hydrovatini)) suggesting recognition of Coelambus and Hygrotus as separate genera, 5) close relationship between the Australian genera of Hydroporini and Hyphydrini and 6) the nesting of Vatellini within a group of Hydroporini.

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.

The World species of the genus Ischnopoda, Stephens are revised and the genus is redefined. The genera Amanota Casey and Rechota Sharp are considered as new synonyms of Ischnopoda. The revised Ischnopoda includes thirty-eight species, 13 of which are described as new: Ischnopoda assingi sp. n., I. boliviana sp. n., I. brasiliana sp. n., I. chilensis sp. n., I. depressa sp. n., I. drugmandi sp. n., I. lingshani sp. n., I. nebulosa sp. n., I. pretiosa sp. n., I. pseudobasalis sp. n., I. rugosa sp. n., I. schuelkei sp. n. and I. spissata sp. n. The following new synonymies are proposed (each first name being valid): Ischnopoda basalis (Cameron, 1923) = Amanota bimarginata Pace, 1996, syn. n.; I. capensis (Casey, 1906) = Falagria arachnipes Fauvel, 1907, syn. n. = Amanota densicollis Pace, 1986, syn. n. = A. rufobrunnea Tottenham, 1957, syn. n.; Ischnopoda rudicollis (Bernhauer, 1934) = Amanota purpurascens Tottenham, 1957, syn. n. = A. wittei Cameron, 1950, syn. n. The following synonym is confirmed: I. leucopus (Marsham, 1802) = Tachyusa chalybea Erichson, 1839. Lectotypes are designated for Amanota capensis Casey, A. semiopaca Cameron, Ischnopoda subaenea Eppelsheim, Rechota impressa Sharp, Staphylinus leucopus Marsham, Tachyusa abyssina Bernhauer, T. burgeoni Bernhauer, T. chalybea Erichson, T. fissicollis Fairmaire et Germain, T. rudicollis Bernhauer, T. scitula Erichson, T. seticornis Sharp, T. sparsa Sharp and T. umbratica Erichson. Twenty-one species are given in new combination. All species are briefly described/redescribed and illustrated. An identification key to the World species of Ischnopoda is provided. A phylogeny of thirty-eight species belonging to the genus Ischnopoda is proposed, based on fifty-two morphological characters. The cladistic analysis provides a single most parsimonious tree. The genus Ischnopoda is redefined and species group are introduced and defined: leucopus group (eleven species), impressa group (nine species) and capensis group (eighteen species).

Parsimony Criterion

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.
