ABSTRACTForty-one species assigned to thirty-seven named genera of trilobites are described from the Tangtou Formation at Tangshan and Lunshan, in Jiangsu Province, SE China. Nankinolithus nankinensis Lu, the Zone fossil of the upper part of the Formation, is abundant. Many Tangtou Formation species occur also in the Huangnehkan, Linhsiang and Chiencaokou formations, and all are considered to be of early Ashgill age. The trilobites are closely related to those of the Staurocephalus clavifrons Zone (Rawtheyan) of Poland, demonstrating the long duration and wide extent of deeper water faunas. There are also close links with the Ashgill faunas of Central Asia.One new species, Amphitryon cheni, is established. The following morphological features are described: a small remopleuridine hypostome is unlike any other in construction; Nileus transversus retains genal spines to full grown size in some specimens, but loses them in others; the hypostome lacks the posteromedian cusp of other species. The hypostome of Paraphillipsinella is strongly styginid in conformation, and unlike that of Phillipsinella. Telephina convexa is the only species known with three spines on the librigena. The arrangement of pits in Nankinolithus nankinensis, the type species, is described, including illustrations of the irregularities which occur in every fringe. A small bulb at the tip of the hypostome of Ovalocephalus (= Hammatocnemis) bears two backwardly pointing spinules, one above the other, on the vertical posterior margin. Three types of protaspides, and numerous meraspid parts are described.

Caragonia gen. nov. is described and placed in the nominate tribe of Cicadellinae, based on a previous phylogenetic analysis of the closely related genus Balacha Melichar. The new genus can be distinguished from other Neotropical genera of Cicadellini by a combination of the following features: crown slightly produced anteriorly, forming nearly a right angle with frons in lateral view; pronotum wider than head with lateral margins convergent anteriorly; female sternite VII with a median longitudinal elevated fold, posterior margin with narrow and deep concavity, lateral margins well produced posteriorly; teeth of second valvulae of ovipositor gradually declivous posteriorly; aedeagus cylindrical and elongate, shaft with base directed anteriorly and then curving gradually posteriorly, with apical pair of processes; paraphyses with stalk longer than rami; and subgenital plates with apex broadly round. Caragonia bella sp. nov. is described and illustrated from Southeastern Brazil (São Paulo and Minas Gerais states) and assigned as the type-species of Caragonia gen. nov. Tettigonia monstruosa Signoret, previously placed in the genus Caragonalia Young, is transferred to the new genus based on characters of the external morphology and female genitalia.

The Bornean Oxypilinae species previously included in the genus Hestiasula Saussure, 1871 are revised. External morphology and genital characters of Sundaian taxa differ considerably from the Indian type species H. brunneriana Saussure, 1871, necessitating taxonomic and nomenclatural changes. The genus Catestiasula Giglio-Tos, 1915 is reinstated. It is characterized by the apomorphic partial fusion of the dorsal and ventral laminae of the left phallomere, and by the complete reduction of the apical process. It is represented on Borneo with two species, C. nitida (Brunner de Wattenwyl, 1893) and C. moultoni Giglio-Tos, 1915. An additional species, C. seminigra (Zhang, 1992) n. comb. occurs in continental SE Asia. Two new genera are described, united by the lack of styli, the presence of dorsal carinae on the subgenital plate, and the unique morphology of the dorsal lamina of the left phallomere, but differing in the morphology of head and forelegs. Astyliasula gen. nov. accommodates A. phyllopus (De Haan, 1842) n. comb. and related species from the Sunda Islands and continental SE Asia: A. basinigra (Zhang, 1992) n. comb., A. hoffmanni (Tinkham, 1937) n. comb., A. javana (Beier, 1929) n. comb., A. major (Beier, 1929) n. comb., A. inermis (Wood-Mason, 1879) n. comb., and A. wuyshana (Yang & Wang, 1999) n. comb.. Hestias sarawaca Westwood, 1889 is removed from synonymy with A. phyllopus and reinstated as A. sarawaca (Westwood, 1889) n. comb.. The monotypic taxon Pseudohestiasula borneana gen. nov. sp. nov. is erected for a Bornean endemic more closely related to Astyliasula than to the other genera. Hestiasula is now restricted to H. brunneriana and related species from India and adjacent countries. The tribe Hestiasulini Giglio-Tos, 1915 stat. rev. is proposed for all genera more closely related to Hestiasula than to other Oxypilinae, that is Hestiasula, Ephestiasula, Catestiasula, Astyliasula, and Pseudohestiasula. New data on the ecology and distribution of all Bornean Hestiasulini as well as a key to the Oxypilinae of Borneo are provided.

The palaemonoid family Anchistioididae Borradaile, 1915 includes a single genus Anchistioides Paulson, 1875 with four known valid species: Anchistioides compressus Paulson, 1875 (type species), A. willeyi (Borradaile, 1899), A. australiensis (Balss, 1921) and A. antiguensis (Schmitt, 1924). Borradaile (1915) suggested two more species within the genus Amphipalaemon Nobili, 1901 (a junior synonym of Anchisitioides Paulson), Amphipalaemon gardineri Borradaile, 1915 (= Anchistioides gardineri) and Amphipalaemon cooperi Borradaile, 1915 (= Anchistioides cooperi) which were later synonomyzed with Anchisitioides willeyi by Gordon (1935), who also suggested their conspecificity with Anchistioides australiensis. At the present time, Anchistioides australiensis is a valid species (Bruce, 1971; Chace & Bruce, 1993) based on specific morphological features such as the presence of sharp postorbital tooth, oblique distal lamela of scaphocerite and sharply produced spines on posterodorsal angles of sixth abdominal somite (see Bruce, 1971: fig. 9). The other Indo-Pacific species, Anchistioides compressus and A. willeyi, can be clearly identified by specific form of scaphocerite, the presence of a well marked blunt postorbital tubercle in A. willeyi which is absent in A. compressus (e.g., Bruce, 1971) and the number of ventral rostral teeth (3-4 large ventral rostral teeth present in A. willeyi while up to 8 small ventral rostral teeth in A. compressus (Paulson, 1875; Gordon, 1935)). Anchistioides antiguensis is clearly separated geographically being known only from the tropical Western Atlantic and Caribbean region (Schmitt, 1924; Holthuis, 1951; Wheeler & Brown, 1968; Martinez-Iglesias, 1986; Markham et al, 1990; Ramos-Porto et al, 1998; Cardoso, 2006).

AbstractThe type species of the genus Butlerius, viz., B. butleri Goodey, 1929, is redescribed and illustrated from specimens collected in South Korea. Additional information is provided for the cuticle, stoma structure, female reproductive system and the male caudal region. The Korean population is 1336-1857 μm long, a = 33.9-43.5, b = 5.41-6.34, c = 3.38-4.20, c′ = 14.13-19.0 and V = 40-45%. Males have spicules 39-49 μm long and a gubernaculum 25-33 μm long. There are nine pairs of genital papillae, three pairs precloacal and six pairs postcloacal. The v5,6,7 clusters are widely separated, one group situated just posterior to the phasmids and the other group at level of pd. Although there are some differences in morphometrics as compared with the type population, the species is easily identified by the similarities in the structure of the stoma, pharynx, spicules and gubernaculum. Butlerius singularis and B. filicaudatus are proposed as synonyms of the type species.

The chirostyloidean squat lobster genus Gastroptychus Caullery, 1896 is revised and is split into two genera: Gastroptychus sensu stricto (type species, Ptychogaster spinifer A. Milne-Edwards, 1880) and Sternostylus new genus (type species, Ptychogaster formosus Filhol, 1884). Gastroptychus sensu stricto, is restricted to nine species with a sternal plastron, at sternite 3, abruptly demarcated from the preceding sternites (excavated sternum) by a distinct step forming a well-defined transverse or concave anterior margin at the articulation with maxillipeds 3, the maxillipeds 3 widely separated, with the distal parts accommodated in the excavated sternum between the left and right maxillipeds 3 when folded, and the P2–4 dactyli with the terminal spine demarcated by a suture. Sternostylus new genus, represented by 12 species, has the sternite 3 anteriorly bluntly produced medially and steeply sloping anterodorsally to the anterior sternite, with a pair of spines directly behind the anterior margin, the left and right maxillipeds 3 adjacent, and the P2–4 dactyli ending in an indistinctly demarcated corneous spine. The above-mentioned characters of Gastroptychus are consistent with Chirostylidae sensu stricto. Published molecular phylogenies indicate, however, that Sternostylus is the sister group to all the other Chirostylidae, and is designated the type genus of a new family, Sternostylidae.

A comparative taxonomic study of Spiribacter and Halopeptonella species was carried out using a phylogenomic approach based on comparison of the core genome, orthologous average nucleotide identity (OrthoANIu), Genome-to-Genome Distance Calculator (GGDC) and average amino acid identity (AAI). Phylogenomic analysis based on 976 core translated gene sequences obtained from their genomes showed that Spiribacter aquaticus SP30T, S. curvatus UAH-SP71T, S. roseus SSL50T, S. salinus M19-40T and Halopeptonella vilamensis DSM 21056T formed a robust cluster, clearly separated from the remaining species of closely related taxa. AAI between H. vilamensis DSM 21056T and the species of the genus Spiribacter was ≥73.1 %, confirming that all these species belong to the same single genus. On the other hand, S. roseus SSL50T and S. aquaticus SP30T showed percentages of OrthoANIu and digital DNA–DNA hybridization of 98.4 % and 85.3 %, respectively, while these values among those strains and the type strains of the other species of Spiribacter and H. vilamensis DSM 21056T were ≤80.8 and 67.8 %, respectively. Overall, these data show that S. roseus SSL50T and S. aquaticus SP30T constitute a single species and thus that S. aquaticus SP30T should be considered as a later, heterotypic synonym of S. roseus SSL50T based on the rules for priority of names. We propose an emended description of S. roseus , including the features of S. aquaticus . We also propose the reclassification of H. vilamensis as Spiribacter vilamensis comb. nov.

The new anchovy Stolephorus grandis n. sp., described on the basis of 10 specimens collected from Papua, Indonesia, and Australia, closely resembles Stolephorus mercurius Hata, Lavoué & Motomura, 2021, Stolephorus multibranchus Wongratana, 1987, and Stolephorus rex Jordan & Seale, 1926, all having double pigmented lines on the dorsum from the occiput to the dorsal-fin origin, a long maxilla (posterior tip just reaching or slightly beyond the posterior margin of preopercle), and lacking a predorsal scute. However, the new species clearly differs from the others in having fewer gill rakers (35–39 total gill rakers on the first gill arch in S. grandis vs. > 38 in the other species), a greater number of vertebrae (total vertebrae 42–43 vs. fewer than 41), longer caudal peduncle (21.9–23.7% SL vs. < 20.8%), and the depressed pelvic fin not reaching posteriorly to vertical through the dorsal fin-origin (vs. reaching beyond level of dorsal-fin origin).

Current Classification

During the last decade, the classification system of chytrids has dramatically changed based on zoospore ultrastructure and molecular phylogeny. In contrast to well-studied saprotrophic chytrids, most parasitic chytrids have thus far been only morphologically described by light microscopy, hence they hold great potential for filling some of the existing gaps in the current classification of chytrids. The genus Zygorhizidium is characterized by an operculate zoosporangium and a resting spore formed as a result of sexual reproduction in which a male thallus and female thallus fuse via a conjugation tube. All described species of Zygorhizidium are parasites of algae and their taxonomic positions remain to be resolved. Here, we examined morphology, zoospore ultrastructure, host specificity, and molecular phylogeny of seven cultures of Zygorhizidium spp. Based on thallus morphology and host specificity, one culture was identified as Z. willei parasitic on zygnematophycean green algae, whereas the others were identified as parasites of diatoms, Z. asterionellae on Asterionella, Z. melosirae on Aulacoseira, and Z. planktonicum on Ulnaria (formerly Synedra). According to phylogenetic analysis, Zygorhizidium was separated into two distinct order-level novel lineages; one lineage was composed singly of Z. willei, which is the type species of the genus, and the other included the three species of diatom parasites. Zoospore ultrastructural observation revealed that the two lineages can be distinguished from each other and both possess unique characters among the known orders within the Chytridiomycetes. Based on these results, we accommodate the three diatom parasites, Z. asterionellae, Z. melosirae, and Z. planktonicum in the distinct genus Zygophlyctis, and propose two new orders: Zygorhizidiales and Zygophlyctidales.
