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.

Orbitolina daviesi Hofker, 1966 (family Orbitolinidae) was validly described and thoroughly illustrated from Thanetian limestones of Pakistan. Although its attribution to the genus Orbitolina d’Orbigny and any phylogenetic relationships with the Cretaceous taxa have been refuted shortly afterwards, the species has not been taxonomically revised since then. Karsella hottingeri Sirel, 1999 was established as new genus and new species from the Thanetian of Turkey, without taking into account J. Hofker’s publication. The original description and genus diagnosis of Karsella has meanwhile been emended to include the occurrence of a radial zone with septula that follow a zig-zag pattern and associated linear arrangement of the foramina, as well as a complex embryo. Orbitolina daviesi clearly displays these features and is here considered a species of the genus Karsella Sirel. Karsella hottingeri is regarded as a subjective junior synonym of O. daviesi Hofker and therefore, the only species of the genus is given as a new combination: Karsella daviesi (Hofker). From a suprageneric viewpoint, the two Paleogene genera Karsella Sirel and Cushmania Silvestri display a complex embryo and might belong to a new subfamily of the Orbitolinidae, phylogenetically different and unrelated to the lower-mid Cretaceous Orbitolininae.

We review the taxonomy of sponge-dwelling shrimp in the “Gambarelloides species group” within the genus Synalpheus Bate 1888, an informal but widely recognized group that is largely endemic to the western Atlantic and contains the majority of Synalpheus species in that region. The validity of most species described from the western Atlantic is reevaluated based on extensive new material from Carrie Bow Cay, Belize, and on examination of types of most described species. Twenty-eight species, including all those historically considered as part of the Gambarelloides group, are herein removed from Synalpheus and transferred to Zuzalpheus, n. gen., which is diagnosed by two synapomorphies: the dense brush of curved setae on the minor first pereopod, and the mesial lamellae on the coxae of the 3 rd pereopods. Six new species are described (Zuzalpheus dardeaui, Z. elizabethae, Z. idios, Z. kensleyi, Z. ul, Z. yano) and Z. osburni (Schmitt 1933) n. comb. is removed from synonymy with Synalpheus goodei. An identification key to all 34 species of West Atlantic Zuzalpheus is presented, as are known host associations, and color plates of most species.

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 phyline plant bug tribe Auricillocorini from Asia is reviewed; 23 species in 6 genera are shown to occur in the Indo-Pacific. A new genus, Artchawakomius, is proposed to accommodate two undescribed, morphologically novel species from Thailand. Nine new species are described from Japanese Ryukyus, Nepal or Thailand: Artchawakomius moteus, A. pius, Cleotomiris miyamotoi, C. yamadakazi, Cleotomiroides tobii, Wygomiris kaliyahae, W. nanae, W. ramae and Zaratus hidekun. Photographic images of living individuals are provided for all new species. The female genitalic structures, which have not been employed for classification of the Auricillocorini, are described and figured for six available species. Wygomiris indochinensis Schuh, known thus far only from Laos, is found also in Thailand; the female is reported for the first time. A checklist of Auricillocorini and a discussion on phylogenetic relationships for all known genera are provided.

Taxonomic Assignments

Two rare and endemic psammophines (Serpentes: Psammophiinae) occur in Angola. The taxonomic status of Psammophylax rhombeatus ocellatus Bocage, 1873 and Psammophis ansorgii Boulenger, 1905 have long remained problematic, with both having varied past and present taxonomic assignments, and whose distributions may therefore present zoogeographic anomalies. Little was known of their biology, habitat associations, or phylogenetic relationships. New material was collected during biodiversity surveys of the Humpata Plateau, near Lubango, Angola. It allowed fuller descriptions of scalation and live coloration for both species, and resolution of their taxonomic status. Genetic analysis confirms that both are distinct at the specific level. In addition, within Psammophis, Jalla’s Sand Snake (Psammophis jallae Peracca, 1896), of which P. rohani Angel, 1925, remains a synonym, is sister to P. ansorgii, and Boulenger’s comment on similarities with P. crucifer are not supported. The status of an unusual skaapsteker from Calueque, Cunene Province, Angola, is discussed and its assignment to Ps. ocellatus is provisional and requires additional material for taxonomic resolution. The new P. ansorgii records from Tundavala represent a range (+400 km southwest) and altitude (1800 m to 2286 m a.s.l) extension from the previous only known precise locality of Bela Vista (= Catchiungo), Huambo Province, whilst that for Ps. ocellatus doubles the known altitude from 1108 m to 2286 m a.s.l and extends the range about 122 km to the northwest from historical material from the plateau of Huíla and Cunene provinces.

A new potamiscine genus, Laevimon, is established for two species of semi-terrestrial freshwater crabs from Vietnam, viz., Laevimon kottelati, new species (type species) and L. tankiensis (Dang & Tran, 1992). The genus is morphologically closest to Hainanpotamon Dai, 1995, but is easily distinguished by distinct sternal and gonopodal characters. The status of Orientalia Dang, 1975, a synonym of Hainanpotamon, as a junior homonym of Orientalia Radoman, 1972 (Mollusca), is also discussed.

Brachiopod Fauna

A brachiopod fauna of late Bathonian age recovered from the Kehailia Formation from Gebel Engabashi in northern Sinai consists of six species (two rhynchonellids and four terebratulids) referred to six genera, of which one genus and two species are new: Globirhynchia sphaerica (Cooper, 1989) new combination, Daghanirhynchia angulocostata Cooper, 1989, Ectyphoria sinaiensis new species, Cooperithyris circularis new genus and species, and new material: Avonothyris species A, and Ptyctothyris species A. The brachiopods described herein comprise a fauna located at the northern part of the Indo–African Faunal Realm within the Jurassic Ethiopian Province. They extend the geographic distribution of those taxa that show great affinity with the Jurassic brachiopod fauna of Saudi Arabia described by Cooper (1989). Differentiation of the endemic faunas that is so characteristic of many of these Ethiopian Province faunas is becoming more well-defined.
