In this contribution, we focus on the status of the genus Micronotus and its four species. After this revision, the genus only includes two of the four species, being synonymized Micronotus dubius n. syn. under M. quadriundulatus; includes within the genus M. andeanum n. comb. (transferred from the genus Tetrix) and confirming the status of M. asperulus. Micronotus is redescribed, including additional characters, and a key is provided to identify the three species considered as valid. Micronotus caudatus, is located in the new genus Danielatettix n. gen., by differing from and not fitting the diagnostic characteristics of Micronotus or another known genus of Tetriginae. The color variation of Danielatettix caudatus n. comb. is documented, and under this species its synonymized: Paratettix attenuata n. syn., P. hastata n. syn. and P. ignobilis n. syn. Finally, the distribution of the studied species and the taxonomic panorama of Tetriginae in the Neotropics are discussed.

Diploscapteroides persicus n. sp. is described and illustrated based on morphological, morphometric and molecular data. The new species is mainly characterised by female body length of 469-673 μm, female tail length of 51-99 μm, shape of gubernaculum and spicules and arrangement of male genital papillae. Also, the arrangement of male genital papillae of the new species shows the presence of precloacal papillae, a feature that has not been previously described for the genus. The new species is comparable with all valid species of the genus, namely D. boettgeri, D. brevicauda, D. chitinolabiatus, D. coroniger, D. dacchensis and D. flexuosus, from which the morphological comparisons of the new species with aforementioned species are discussed. Phylogenetic analyses using partial sequences of SSU and LSU rRNA genes were performed for the new species, being the first representative of the genus to be phylogenetically studied using both Bayesian inference (BI) and maximum likelihood (ML) methods, and revealed that D. persicus n. sp. formed a clade with a species of Cephaloboides.

Phylogenetic Hypotheses

Syllid annelids from the so-called ‘ribbon clade’ are flattened, ribbon-shaped worms of the genera Parahaplosyllis Hartmann-Schröder, 1990, Eurysyllis Ehlers, 1864, Xenosyllis Marion & Bobretzky, 1875, Trypanosyllis Claparède, 1864, Ramisyllis Glasby, Schroeder & Aguado, 2012, Trypanobia Imajima & Hartman, 1964, Plakosyllis Hartmann-Schröder, 1956, Pseudosyllis Grube, 1863 and Trypanedenta Imajima & Hartman, 1964. Some species possess a remarkable reproductive strategy using multiple stolons that has been recently suggested to be ancestral to the group. Here, to evaluate the evolution of reproductive modes in the group, we assess, for the first time, the phylogenetic relationships within the ribbon clade and related genera. We collected new material of Trypanobia and Trypanosyllis from Japan, Spain, Philippines and Indonesia and sequenced it for the nuclear markers 18S rRNA and the mitochondrial markers 16S rRNA and cytochrome c oxidase I for phylogenetic inference and also performed ancestral character reconstruction for the reproductive strategy in the entire group. Formal taxonomic descriptions of a new genus and six new species are provided. The new genus, Trypanospina, gen. nov., is characterised by the spines that cover its surface. Most genera within the ‘ribbon clade’ are monophyletic and the relationships appeared well supported in most cases. However, our phylogenetic hypotheses are not conclusive in regard to the relationships of the genera Trypanedenta and Trypanobia, nor to the status of those to genera as distinctive, since they seem to be paraphyletic and they appear in low-supported clades. In contrast, our results shed light on the evolution of the reproductive modes within the group, showing that scissiparity (development of a single stolon each time) is the ancestral character for the entire group and gemmiparity (development of more than one stolon at the same time) then appeared twice in two independent clades.

First Time

A taxonomic revision of the tribe Ceroptresini (Hymenoptera: Cynipidae) is conducted for the first time. Prior to this study, the total number of valid species of Ceroptres, the only genus within Ceroptresini to date, was 23. As a result of this revision, 15 Ceroptres species are retained as valid and one species, Amblynotus ensiger Walsh, 1864, is desynonymized from Ceroptres petiolicola (Osten-Sacken, 1861), being considered here as a valid Ceroptres species: C. ensiger (Walsh, 1864) status verified and comb. nov. An additional five new species are described from Mexico: Ceroptres junquerasi Lobato-Vila & Pujade-Villar sp. nov.; C. lenis Lobato-Vila & Pujade-Villar sp. nov.; C. mexicanus Lobato-Vila & Pujade-Villar sp. nov.; C. nigricrus Lobato-Vila & Pujade-Villar sp. nov.; C. quadratifacies Lobato-Vila & Pujade-Villar sp. nov., increasing the total number of valid Ceroptres species to 21. Ceroptres masudai Abe, 1997 is synonymized with C. kovalevi Belizin, 1973. Ceroptres niger Fullaway, 1911 is transferred to Andricus (Andricus confusus Lobato-Vila & Pujade-Villar comb. nov. and nom. nov.). Five species (Amblynotus inermis Walsh, 1864; Cynips quercusarbos Fitch, 1859; Cynips querficus Fitch, 1859; Cynips quercuspisum Fitch, 1859; and Cynips quercustuber Fitch, 1859) are not considered as valid Ceroptres. The status of Ceroptres quereicola (Shinji, 1938), previously classified as an unplaced species, is commented on. In addition, a Nearctic species from the USA, Ceroptres politus Ashmead, 1896, is here proposed as the type species of a new genus within Ceroptresini: Buffingtonella Lobato-Vila & Pujade-Villar gen. nov. Redescriptions, biological and distribution data, illustrations and keys to genera and species within Ceroptresini are provided. The diagnostic morphological traits of Ceroptresini, Ceroptres and the new genus are discussed.

First Time

The status of two supposedly myrmecophilous Australian 'Glyptoma' species described by A. M. Lea is reviewed, and lectotypes designated for both species. A new genus, Myrmelibia, is proposed for Glyptoma kingi Lea of south-eastern Australia. This genus is not related to Glyptoma or Thoracophorus, but belongs near the genera Eulibia, Heterotrochinus and Holotrochidius of the Oriental-Indian Ocean region. New records confirm that M. kingi is one of the few truly myrmecophilous osoriines, probably host-specific with Zridomyrmex nitidus Mayr (Hymenoptera : Formicidae : Dolichoderinae). Glyptoma myrmecophilum Lea is transferred to the genus Thoracophorus as a senior synonym of T. quadricostatus Bernhauer (new synonymy); present evidence suggests it is free-living and subcortical, not myrmecophilous. A key to all 16 genera of Osoriinae (sensu Blackwelder) known to occur in Australia is presented, along with the names, distribution and microhabitat of Australian species included in each genus. Four genera (Allotrochus, Arpagonus, Espeson, and Saegerius) are reported from Australia for the first time, each based on undescribed species from northern Queensland.

Remarks on Inachoididae Dana, 1851, with the description of a new genus and the resurrection of Stenorhynchinae Dana, 1851, and recognition of the inachid subfamily Podochelinae Neumann, 1878 (Crustacea, Decapoda, Brachyura, Majoidea)

The Status

A new inachoidid genus Paulita n. gen. is established for Paradasygyius tuberculatus (Lemos de Castro, 1949), from thewestern Atlantic. Paulita tuberculata (Lemos de Castro, 1949) n. comb. differs from Paradasygyius depressus (Bell,1835), from the eastern Pacific, the type species and only remaining species of Paradasygyius Garth, 1958, by a numberof characters mainly related to the carapace, thoracic sternum, abdomen, and first gonopod. Paulita n. gen. shares the di-agnostic characters of Inachoididae Dana, 1851, in particular the latero-external parts of pleurites 5–8 that extend beyondeach side of the carapace and are calcified and ornamented like the carapace, resulting in the insertion of the carapace intoa setting gutter. Stenorhynchus Lamarck, 1818, is transferred from Inachidae to Inachoididae, and the subfamily Steno-rhynchinae Dana, 1851, is resurrected. Inachoididae now consists of at least two subfamilies: Inachoidinae Dana, 1851,and Stenorhynchinae, whereas the status of Salaciinae H. Milne Edwards & Lucas, 1842, remains uncertain. The status ofseveral other American genera traditionally included in Inachidae is discussed, leading to the recognition of the followingsubfamilies besides the Inachinae emend.: Podochelinae Neumann, 1878, which is here resurrected, Anomalopodinae Stimpson, 1871, and perhaps also Eucinetopinae Števčić, 2005.

Current Emphasis

A checklist of Recent and fossil catfishes (Order Siluriformes) is presented, summarizing taxonomic literature published through 2005. From 4624 nominal species group names and 810 genus group names, 3093 species are recognized as valid, and are distributed among 478 genera and 36 families. Distributional summaries are provided for each species, and nomenclatural synonymies, including relevant information on all name-bearing types, are included for all taxa. One new name is proposed herein: Clariallabes teugelsi, as a replacement for Clarias (Allabenchelys) dumerili longibarbis David & Poll, 1937, which is preoccupied by Clarias longibarbis Worthington, 1933, but has been treated as a valid species of Clariallabes by Teugels. Acrochordonichthys melanogaster Bleeker, 1854, is designated as type species of Acrochordonichthys Bleeker, 1857, inasmuch as no earlier valid designation has been found. A new genus Pseudobagarius, is proposed for the “pseudobagarius group” of species formerly placed in Akysis. The status of 228 species group names remains unresolved and 31 names based on otoliths ascribed to catfishes are listed but not placed into the checklist. The current emphasis given to catfish taxonomy at present is likely to result in a dramatic increase in the total number of valid taxa as well as major changes in the membership of some of the higher level taxa recognized here.

Morphological And Molecular Data

The systematics of South American Xenodontinae snakes has experienced large changes and improvements as a result of recent studies employing molecular data. Herein we assess the status of the rare Peruvian snake species, Erythrolamprus problematicus (Dipsadidae, Xenodontinae, Xenodontini), previously known from a single specimen collected in 1950. Based on new morphological and molecular data from a second specimen that we collected, we confirmed the presence of a crease in the rostral scale, mentioned in the original description (a unique trait among the Xenodontini), and recovered E. problematicus as the sister-taxon of all other Xenodontini, instead of nested among the current Erythrolamprus. Therefore, our phylogenetic results justify the erection of a new genus to accommodate the species.

A new candonid genus,Schornikovdonagen. nov., with its type speciesSchornikovdona bellensissp. nov., is described from rheocrene springs of Bell County, Texas. It is designated to the tribe Candonini due to the smooth carapace surface, normal pore openings with sensory seta, the presence of a 5-segmented first antenna, two long sexual bristles on the second antenna in males, the narrowly fused terminal segment of the Md palp, a long penultimate segment of the Mxl palp, two long and one short setae on the terminal segment of T3, the absence of an “e” seta on T3, the presence of a posterior seta on the uropod, the presence of 5 + 2 rows of spines on Zenker’s organ, and other characteristics found in the tribe. The main diagnostic characteristics separating the new genus from the other genera in the tribe are the shape of the carapace, the reduced numbers of segments in the first antenna, reduction or absence of exopodial setae in the second antenna, asymmetrical clasping organs, the uropod with one rod-shaped claw, the different shape of the hemipenis, and differences in parts of the chaetotaxy. Based on these differences, we proposeSchornikovdonagen. nov. as a new genus, with the new speciesS. bellensissp. nov., in the subfamily Candoninae in the family Candonidae.
