The Moluccan net-winged beetle fauna remains poorly studied and here, new species of Schizotrichalus Kleine, 1926 and Eniclases Waterhouse, 1879 are reported from Halmahera. Using morphological traits and cox1 mitochondrial DNA sequences, we propose two new species, Eniclases kusyi sp. nov. and Schizotrichalus halmaherensis sp. nov., and redescribe E. moluccanus Kleine, 1930. New molecular data confirm morphology-based sister relationships between Schizotrichalus and Eniclases and the analysis identifies the combined area of the present-day Halmahera and New Guinea as an ancestral area of these genera. Now, Halmahera and New Guinea are quite similar in respect of the number of trichaline genera. Concerning the size of islands and the recent origin of the nowadays northern Moluccas, these results are unexpected and thus the general validity of this distribution pattern should be confirmed with other groups of beetles.

Left-eyed flounders of the genus Chascanopsetta Alcock 1894 (Bothidae) occur in the Indian, Pacific, and Atlantic oceans at depths ranging from 120 to 1500 meters. They possess some unique features in bothid fishes including a strongly compressed and elongated body and a tremendously large mouth. Currently, nine species of Chascanopsetta are recognized, and three of them (C. micrognatha Amaoka & Yamamoto 1984, C. lugubris Alcock 1894 and C. prognatha Norman 1939) are distributed in the West Pacific. We collected 25 specimens of Chascanopsetta during 11 biodiversity expeditions carried out mainly in the West Pacific. Among them, eight specimens taken off Papua New Guinea present morphological features that differ from those of the three nominal species known in the West Pacific. In this study, we examined these eight specimens of unknown affinity and compared their morphology to that of specimens of other congeneric species. Results of these comparisons showed that these specimens represent an undescribed species of Chascanopsetta, named herein, C. novaeguineae sp. nov.. The new species resembles C. elski Foroshchuk 1991, which is known only from the Saya de Malha Bank in the western Indian Ocean, in having a high number of gill rakers (> 13). However, the combination of the following characters further distinguishes C. novaeguineae sp. nov. from C. elski: longer jaws, narrower interorbital width, and number of pseudobranches (21–25 vs. 26–27). The DNA sequences from the mitochondrial cytochrome oxidase subunit I (COI) gene from C. novaeguineae sp. nov. and other species were obtained and compared to confirm its taxonomic status and to infer its tentative phylogenetic position within the Chascanopsetta.

Broad Concept

Recent studies on the fungal families Lophiostomataceae and Lophiotremataceae (Pleosporales) have provided varying phylogenetic and taxonomic results concerning constituent genera and species. By adding DNA sequences of 24 new strains of Lophiostomataceae and nine new strains of Lophiotremataceae to a sequence data matrix from international databases, we provide a new understanding of the relationships within these families. Multigene analysis of the four molecular markers ITS, LSU, TEF1-α, and RPB2 reveals that the genera within Lophiotremataceae are phylogenetically well supported. Lophiostoma myriocarpum is recognised as a species of Lophiotrema in contrast to earlier concepts. In Lophiostomataceae, we resurrect a broad generic concept of the genus Lophiostoma and reduce 14 genera to synonymy: Alpestrisphaeria, Biappendiculispora, Capulatispora, Coelodictyosporium, Guttulispora, Lophiohelichrysum, Lophiopoacea, Neopaucispora, Neotrematosphaeria, Platystomum, Pseudocapulatispora, Pseudolophiostoma, Pseudoplatystomum, and Sigarispora. Nine new species are described based on molecular data and in most cases supported by morphological characters: Antealophiotrema populicola, Atrocalyx nordicus, Lophiostoma carpini, Lophiostoma dictyosporium, Lophiostoma erumpens, Lophiostoma fusisporum, Lophiostoma jotunheimenense, Lophiostoma plantaginis, and Lophiostoma submuriforme. Lophiostoma caespitosum and Lophiotrema myriocarpum are lecto- and epitypified to stabilise their species concepts. High intraspecific variability of several morphological traits is common within Lophiostomataceae.

Common Group

The nematode diversity in soil and litter was investigated on Mount Hamiguitan, the Philippines, along four eco-habitats from elevations of 75-1600 m a.s.l. A total of 155 and 467 nematodes were identified to 39 and 62 genera from litter and soil, respectively. The nematode assemblages and diversity did not show any relation to eco-habitat or elevation. Bacterivorous nematodes were the most common group (37.5%). Acrobeloides was most abundant from the soil and Aphelenchoides from the litter. Bicirronema hamiguitanense n. sp. is herein described based on morphology, morphometrics and molecular data. The new species has the following diagnostic features: a wide lateral field one-fifth of its body diam. with four incisures forming two ornamented ridges; gubernaculum with proximal thickening; spicules (35-38 μm) and gubernaculum (18-20 μm) longer than B. caledoniense; and with 37 molecular autapomorphies supporting its new species status. The phylogenetic position of the new species within Cephalobomorpha is discussed.

Morphological And Molecular Data

The genus Onychelmis Hinton, 1941 was for a long time regarded as a small taxon with only three known species distributed in the Andes. A study of new material from Ecuador, using morphological and molecular data, has resulted in the discovery of five new species: Onychelmis lenkae sp. nov., O. lobata sp. nov., O. minor sp. nov., O. onorei sp. nov. and O. splendida sp. nov. We also revised the entire genus and redescribed the three known species, O. longicollis (Sharp, 1882), O. leleupi Delève, 1968 and O. whiteheadi Spangler & Santiago, 1991. Habitus photographs of adults are provided, together with line drawings of male and female genitalia, and schematic illustrations of the distribution of femoral tomentum for each species. DNA sequences for barcoding the COI mtDNA fragment were used to support species delimitation and to suggest possible relationships among species. The revision includes a key to adults of all species of Onychelmis and notes on the biogeography of the genus, with an updated distribution map.

A New Species

A new species of the genus Caecilia (Caeciliidae) from the western foothills of the Serranía de los Yariguíes in Colombia is described. Caecilia pulchraserranasp. nov. is similar to C. degenerata and C. corpulenta but differs from these species in having fewer primary annular grooves and a shorter body length. With this new species, the currently recognized species in the genus are increased to 35. Mitochondrial DNA sequences, including newly sequenced terminals representing two additional, previously unanalyzed species, corroborate the phylogenetic position of the new species within Caecilia and the monophyly of the genus. This analysis also included newly sequenced terminals of Epicrionops aff. parkeri (Rhinatrematidae) and trans-Andean Microcaecilia nicefori (Siphonopidae). Evidence was found for the non-monophyly of the family Siphonopidae and the siphonopid genera Microcaecilia and Siphonops. The implications of these results for caecilian systematics are discussed and the status of the trans-Andean populations of Caecilia degenerata is commented upon.

The taxonomy of Old World Trigonidiinae (sword-tailed crickets) is in need of major revision. This includes its type genus Trigonidium. Various authors have different opinions on what constitutes the subgenera and species of Trigonidium s. l. and this has led to considerable confusion and inconsistencies. Recent use of molecular data has helped make some progress in resolving some of these problems, but there are still limitations. In this paper, we aim to provide a baseline to resolve the confusion in the taxonomy of Trigonidium s. l. Firstly, we provide a literature review of the contentious taxa related to Trigonidium and also provide some recommendations on future work for Trigonidium s. l. Secondly, we reanalysed the gene tree (sensu Lu et al., 2018) using more DNA sequences from GenBank to test whether Trigonidium s. str. and Paratrigonidium should be considered separate genera or subgenera of Trigonidium s. l. However, the gene tree based on current data was not conclusive. Lastly, we describe a new species of Trigonidium s. str. from Siargao Island, Mindanao (Philippines): Trigonidium solis sp. nov.

Morphological And Molecular Data

The Neotropical frog genus Cryptobatrachus includes six currently recognized species distributed throughout the northern Andes in Colombia and Venezuela. Cryptobatrachus conditus, C. pedroruizi, and C. remotus were described from the Colombian and Venezuelan slopes of the Serranía del Perijá. Due to the great morphological similarity among these species, we re-assess their taxonomic status based on morphological and molecular data from types, topotypes, and specimens from localities referred to in the original descriptions of these species. Morphometric comparisons showed that all these species are virtually indistinguishable, although some subtle qualitative differences in morphological traits distinguish C. conditus from the other species. Phylogenetic analyses of DNA sequences found that C. remotus and C. pedroruizi are not reciprocally monophyletic and exhibit low genetic divergence (< 1 %). Therefore, C. remotus should be considered a junior synonym of C. pedroruizi. This work stresses the importance of comprehensive taxon sampling in poorly explored areas, especially between neighbouring countries.

A New Species

A new species, Anurophorus hallaensis sp. nov. was collected from the withered leaves of Korean fir (Abies koreana Wilson), which is distributed at higher than 1,300 m in altitude on Mt. Hallasan (Jeju Island, South Korea). The morphology and two partial gene regions of this species are described herein. Anurophorus hallaensis sp. nov. showed the same formulas of macrochaetae and sensilla on thoracic segment II to abdominal segment IV as those exhibited by A. laricis Nicolet and A. palearcticus Potapov; however, this new species can be distinguished from them by the number of knobbed hairs on ventral side of legs. Partial DNA sequences of the mitochondrial Cytochrome c Oxidase subunit I (COI) gene and ribosomal DNA (28S rDNA) were used as DNA barcodes to distinguish between A. hallaensis sp. nov. and closely related congeners. The results of the present study indicate that the COI and rDNA are useful for species discrimination within the genus Anurophorus. An identification key to the Korean species of Anurophorus is provided.
