Definition Of

The phylogenetic analysis of Sergestoidea based on 253 morphological characters and encompassing all 99 valid species confirmed all previously recognized genus-level clades. Analysis retrieved five major robust clades that correspond to families Luciferidae, Sergestidae, Acetidae fam.n., Sicyonellidae fam.n. and Petalidiumidae fam.n. Synonymy, emended diagnoses and composition of revealed family-level clades are provided. Three types of morphological characters were important in the phylogeny of the Sergestoidea: general external characters, copulatory organs, and photophores. Novel metrics to quantify the contribution of these character types were tested. General external characters were significant in supporting the major clades (80% of the families and nearly half of the genera). Copulatory organ characters and photophores greatly supported the medium-level clades: Lucifer, Belzebub , Petalidium, Neosergestes, Challengerosergia (copulatory organ characters) and Lucensosergia , Challengerosergia, Gardinerosergia , Phorcosergia (photophores). An evolutionary model of the Sergestoidea showing their pathways into their principal biotopes is proposed: the major clades evolved in a vertical direction (from epi- to bathypelagic); further divergence at the genus level occurred within vertical zones in a horizontal direction, with the invasion of the benthopelagic and neritic (shelf and estuarine) habitats and speciation within these domains.

Character Assessment

The first comprehensive phylogenetic analysis of the family Rhacophoridae was conducted by Liem (1970) scoring 81 species for 36 morphological characters. Channing (1989), in a reanalysis of Liem’s study, produced a phylogenetic hypothesis different from that of Liem. We compared the two studies and produced a third phylogenetic hypothesis based on the same characters. We also present the synapomorphic characters from Liem that define the major clades and each genus within the family. Finally, we summarize intergeneric relationships within the family as hypothesized by other studies, and the family’s current status as it relates to other ranoid families.

The Frankliniella genus-group comprises over 270 species in ten genera. It is one of the important groups in Thripinae, and includes some important pests. A phylogenetic analysis of genus-level relationships within the Frankliniella genus-group was performed, based on 55 morphological character states scored for 23 species representing 11 genera, including an outgroup, Thrips physapus. Six most parsimonious trees were generated from the analysis under equal weighting schemes. Pseudanaphothrips was recovered as monophyletic, and as sister group to a clade comprising five genera, Yaobinthrips, Parabaliothrips, Sitothrips, Firmothrips, Kakothrips, in which Parabaliothrips showed to be a paraphyletic group. Frankliniella was paraphyletic, with Frankliniella zizaniophila + Iridothrips + Pelikanothrips kratochvili forming one clade that was sister group to the rest of the species of Frankliniella + Guerothrips moundi. According to the phylogenetic analysis, Guerothrips is proposed as a new synonym of Frankliniella, and Pelikanothrips is considered a new synonym of Iridothrips. The genus Iridothrips is revised with a key to five species, including I. zizaniophila comb.n., I. kratochvili comb.n. and I. lobulatus sp.n.. A key to the eight members of the Frankliniella genus-group is provided.

First Time

A generic-level phylogenetic analysis of the tribe Torneutini Thomson, 1860 is presented based on 72 morphological characters for 39 terminal taxa of which, 31 are representatives of the Torneutini genera. The outgroup includes eight representatives from other tribes. A hypothesis of monophyly for supertribe Trachyderoinia Dupont, 1836 (sensu Fragoso, Monné and Seabra 1987) is presented for the first time. Torneutini, as currently recognized, was shown to be paraphyletic. In order to eliminate this condition, Bothriospilina Lane, 1950 is raised herein to tribe level. Torneutini, as herein defined, comprises the following genera in parenthetic notation: (Macellidiopygus (Psygmatocerus (Gigantotrichoderes (Spathopygus + Coccoderus) (Gnathopraxithea + Praxithea) (Torneutopsis (Torneucerus + Diploschema) (Torneutes (Dragomiris + Dragoneutes) (Thaumasus + Xenambyx)))))). The maintenance of Macellidiopygus in Torneutini needs further investigating. Bothriospilini Lane, 1950, new status, includes in parenthetic notation: ((Ranqueles + Scapanopygus) (Taygayba (Delemodacrys (Bothriospila + Timbaraba))) (Gnaphalodes (Knulliana + Chlorida)))). The position of Chrotoma is still no certain, and it is tentatively included in Bothriospilini. The results indicate that Bothriospilini is closely related to Trachyderini, Pyrestini and Basipterini. A phylogenetic classification of Trachyderoinia at tribe level, and of Torneutini and Bothriospilini at genus level, is proposed.

Genus-level taxa in the oribatid mite superfamily Galumnoidea (Acari, Oribatida) are revised based on morphology of adults and a previously published phylogenetic analysis. We give a concise overview of the general morphology of Galumnoidea, diagnoses and a key for families, genera, and subgenera, and a taxonomic list with two families, 39 genera, 9 non-nominal subgenera, and 590 species. The following nomenclatorial changes to genus-group taxa resulted from our revision: Allogalumna (Allogalumna) Grandjean, 1936 (=Xenogalumna Balogh, 1960(b) syn. nov.), Flagellozetes (Cosmogalumna) Aoki, 1988 comb. nov.

Supplementary Data

In the present study, we provide supplementary data for Myxidium cf. rhodei Léger, 1905 based on morphological, histological and molecular characterization. M. cf. rhodei was observed in the kidneys of 918 out of 942 (97%) roach Rutilus rutilus (Linnaeus, 1758). Myxospores of M. cf. rhodei were fusiform with pointed ends, measuring 12.7 ± 0.1 SD (11.8-13.4) µm in length and 4.6 ± 0.1 (3.8-5.4) µm in width. Two similar pear-shaped polar capsules were positioned at either ends of the longitudinal axis of the myxospore: each of these capsules measured 4.0 ± 0.1 (3.1-4.7) µm in length and 2.8 ± 0.1 (2.0-4.0) µm in width. Polar filaments were coiled into 4 to 5 turns. Approximately 18-20 longitudinal straight ridges were observed on the myxospore surface. The suture line was straight and distinctive, running near the middle of the valves. Histologically, the plasmodia of the present species were found in the Bowman’s capsules, and rarely in the interstitium of the host. Phylogenetic analysis revealed that M. cf. rhodei was sister to M. anatidum in the Myxidium clade including most Myxidium species from freshwater hosts.
