Hepatic Clostridium Perfringens Abscess Enhancement right after Radiofrequency Ablation Treatment regarding Hepatocellular Carcinoma: Document of a Rare Circumstance.
A new species of deepwater gurnard, Pterygotrigla (Otohime) madagascarensis sp. nov. is described, based on two specimens collected on the upper continental slope south of Madagascar, in the southwestern Indian Ocean. The new species belongs to the tropical Indo-Pacific subgenus Otohime in having a short rostral projection, short posttemporal spine, long opercular spine and no cleithral spine. It is most similar to P. (O.) multipunctata, and P. (O.) urashimai, in having no large blotch on the first dorsal fin, a jet-black blotch and no white ocellus on the inner pectoral-fin surface, with no scales on the breast and front of the pectoral-fin base. However, the new species differs from the latter two species by the combination of the following characters first dorsal-fin spines 7, second dorsal-fin rays 12, dusky rays on the inner pectoral-fin surface, one row of blackish botches on second dorsal fin, and no papillae on the dorsal surface of oral cavity. A key is provided for the twelve Pterygotrigla species now in the subgenus Otohime.Findings of a new representative of the Laophontodinae Lang, 1944 (Copepoda, Harpacticoida) from the Napoleon Reef (Gulf of Aqaba, Red Sea, Egypt) provided new insights into the systematics of the type genus Laophontodes T. Scott, 1894. Bicorniphontodes clarae gen. et sp. nov., which is described in the present contribution, shares exclusively six derived characters with Laophontodes bicornis A. Scott, 1896, L. horstgeorgei George Gheerardyn, 2015, and partly with L. hamatus (Thomson, 1883), and L. ornatus Krishnaswamy, 1957 (1) cephalothorax medio-laterally with triangular extensions and (2) postero-laterally with paired cuticular processes, (3) free body somites except telson dorsally with hyaline frills ending in rounded lappets, (4) furcal setae I and II displaced subapically, (5) antennar allobasis lacking abexopodal seta on endopodal half, (6) outer spines of the last segment of swimming legs 2 and 3 unipinnate and comb-like, with the pinnae being extremely long and set widely apart. Thus, the named species are excluded from Laophontodes and united together with B. clarae gen. et sp. nov. in Bicorniphontodes gen. nov. as Bicorniphontodes bicornis comb. nov., B. hamatus comb. nov., B. horstgeorgei comb. nov., and B. ornatus comb. nov.. Beside the description of B. clarae gen. et sp. nov., a detailed phylogenetic discussion regarding the systematic relationships of the named species and the justification of the erection of Bicorniphontodes gen. nov. is given, including its distribution in the world's oceans. A key to species is also provided.The scorpion-tailed orb-weaving spiders in the genus Arachnura Vinson, 1863 (Araneidae Clerck, 1757) are revised for Australia and New Zealand. Arachnura higginsii (L. Koch, 1872) only occurs in Australia and A. feredayi (L. Koch, 1872) only in New Zealand. A single female collected in south-eastern Queensland (Australia) is here tentatively identified as A. Selleckchem PCI-32765 melanura Simon, 1867, but it is doubtful that this species has established in Australia. Two juveniles from northern Queensland do not conform to the diagnoses of any of the above species and are illustrated pending a more thorough revision of the genus in South-East Asia and the Pacific region. An unidentified female from Westport (New Zealand) does not conform to the diagnoses of A. feredayi and A. higginsii, but is not described due to its poor preservation status. Arachnura caudatella Roewer, 1942 (replacement name for Epeira caudata Bradley, 1876), originally described from Hall Sound (Papua New Guinea) and repeatedly catalogued for Australia, is considered a nomen dubium.Plumachaetas Salmon is a genus of Entomobryoidea with 11 valid species, all from Oceania. The genus is characterised by the presence of lanceolate scales, the subapical chaeta of the maxillary outer lobe thick and blunt, dental spines absent and a short mucro. In this paper we describe four new species of Plumachaetas from Oceania P. belae sp. nov., P. loriensis sp. nov., P. mamuensis sp. nov. and P. wanangensis sp. nov. Plumachaetas belae sp. nov. and P. mamuensis sp. nov. are similar to each other, and to P. queenslandica (Schött) and P. yoshii Zhang Deharveng, but are unique in the combination of dorsal and labial chaetotaxy. Plumachaetas loriensis sp. nov. resembles P. halmaherae (Yoshii Suhardjono) and P. sunae Zhang Deharveng but differs in labial, dorsal chaetotaxy and unguiculus shape. Plumachaetas wanangensis sp. nov. is similar to other taxa bearing a mucro with four teeth, but presents a unique combination of macrochaetae on thoracic and abdominal segments. All species are arboreal and were collected in Malaise traps set in humid rainforests. A map of the geographic distribution and ecological remarks on the genus are provided and a key to species with a table summarising the main morphological features of all described taxa in the genus.Four new species of Corethrella are described from Brazil. Corethrella xokleng sp. n. and C. cambirela sp. n. are described from males and females, and Corethrella yanomami sp. n. and C. munteantaroku sp. n. are described from a female and male, respectively. Fourteen Corethrella species have new distributional records, with five of these being first records for Brazil. The number of valid species of Corethrellidae known from Brazil is increased from 37 to 46.Identification keys are provided for the final (4th) instar larvae of genera of Chironomidae (Diptera), from aquatic habitats in Australia and New Zealand. Morphological features of taxonomic utility are discussed and illustrated by line drawings. Summaries of described species for each genus and their distribution is provided, with reference to means of further identification where available. In the subfamily Podonominae, 5 genera are keyed of which 3 are recorded from New Zealand; the 4 genera of Aphroteniinae are from Australia (absent from New Zealand); in Diamesinae 1 genus is Australian, 2 are from New Zealand; in the Tanypodinae 21 genera are found in Australia and 4 are from New Zealand; in Orthocladiinae 31 genera are reported from Australia, 14 from New Zealand; and in Chironominae 43 genera are keyed from Australia, 9 from New Zealand. Larvae of Axarus Roback, Chernovskiia Sæther and Omisus Townes (Chironomini) are recognised in Australia for the first time. The undescribed larva of Paucispinigera Freeman, endemic to New Zealand, is keyed and several other New Zealand taxa are included based on unpublished records.
