Trichotylenchus gorganiensis n. sp. is described and illustrated based on morphological and morphometric data. The new species is characterized by its 760–1073 µm long body, conoid-rounded lip region continuous with the body contour and bearing 5–7 fine striae, 22.0–24.5 µm long stylet, basal pharyngeal bulb offset or slightly overlapping intestine, post-anal sac extending 50–73 % of the tail region, and cylindrical or subclavate tail with a striated terminus. Differences of the new species from the closely related species T. astriatus, T. astriatoides, T. changlingensis and T. papyrus are discussed. Photomicrographs and several taxonomic notes on 13 other species of Telotylenchinae, collected from Iran, are provided.

The present paper deals with a description of two new species of crickets of the subfamily Podoscirtinae (Orthoptera: Gryllidae), Trelleora khasiana sp. nov. and Indotrella maculata sp. nov., from India; besides, some additional morphological characteristics of the already reported species, Indotrella angusta Gorochov, 2003 is also presented. The morphological characterization of these two new species is supported with suitable line diagrams and plates. A checklist of crickets of Podoscirtinae for the Asia-tropical region is included.

AbstractMolecular and morphological characterization of two species of Cucullanidae from freshwater fish in Brazil are provided, one of which represented an undescribed taxon. Cucullanus opisthoporus n. sp. was collected in Cichla melaniae from River Xingu, State of Pará, and in C. pinima from River Jamarí, State of Rondônia. Nematodes referable to Cucullanus grandistomis were collected in Oxydoras niger from River Xingu. The new species has an appendage in the tail tip, ventrally covered by small spines, which is an exclusive feature of Cucullanus tucunarensis. However, C. tucunarensis differs from C. opisthoporus n. sp. based upon the relative position of deirids and the excretory pore, which are more posterior from the oesophageal end in the new species. Observations of C. tucunarensis type specimens also revealed features that were wrongly or not reported in the original description. Type specimens of C. grandistomis were observed, although they were poorly preserved. After evaluation of newly collected specimens of C. grandistomis, features unreported in the original description were observed for the first time, including the presence of an intestinal caecum. Thus, C. grandistomis was transferred to Dichelyne. Sequences of the 18S and 28S rRNA genes revealed high genetic similarity between the specimens of C. opisthoporus n. sp. from the two different hosts as well as their genetic distance from Dichelyne grandistomis n. comb. Phylogenetic reconstructions using representatives of Cucullanidae suggested the artificiality of the current morphological system adopted to separate the genera, since most genera were not monophyletic, although the availability of genetic data is still fragmented.

The circumscription and morphological characterization of the deltocephaline tribe Acostemmini is revised based on dis-coveries of new and poorly known taxa from recent collections in Madagascar and from examination of the type speci-mens of Alocoelidia fulva Evans, Iturnoria insulana Evans, and Protonesis delegorguei Spinola. Alocoelidia Evans 1954,Caelidioides Signoret 1880, Iturnoria Evans 1954, and Protonesis Spinola 1850 were previously placed in Coelidiinaebut were later removed from the subfamily and until now have been unplaced to subfamily are placed here in Deltocepha-linae: Acostemmini, new placement. A new genus and species, Ikelibeloha cristata gen. n., sp. n., are described that havean unusually modified structure of the head and a large, crested pronotum. Molecular data (28S, Histone H3 genes) wereobtained for Ikelibeloha and Iturnoria, and analyzed with other members of Deltocephalinae. Results of the phylogeneticanalyses show strong support for the monophyletic clade ((Acostemma, Eryapus), (Ikelibeloha, Iturnoria)) and thus a re-lationship between previously described Acostemmini, Ikelibeloha, and Iturnoria has strong statistical support, and aclose relationship is inferred between these and the morphologically similar Alocoelidia, Caelidioides, and Protonesis.Two new species of Alocoelidia, A. maurae sp. n. and A. chasei sp. n. are described, and the genus is redescribed. Themale genitalia of Caelidioides tristis (Signoret), Iturnoria insulana, Alocoelidia fulva, and Acostemella rubra Evans areillustrated and described for the first time. The female genitalia of A. fulva, C. tristis and I. insulana are described and thefirst and second valvulae of C. tristis are illustrated. The habitus and face of Protonesis delegorguei are illustrated and thegenus is redescribed. The characters traditionally used to define Acostemmini are reviewed with notes on their known de-grees of variation, and characters that differentiate Acostemmini from the closely related tribe Stegelytrini are discussed.The type of Malagasiella minima Evans was also examined, and Malagasiella Evans, 1954 is considered a junior syn-onym of Doratulina Melichar, 1903 (Deltocephalinae: Stenometopiini), syn. n. giving the new combination Doratulina minima (Evans) comb. n.

The new species Diabrotica wartensis Cabrera & Sosa-Gómez was found feeding on roots and leaves of sunflower and soybean in the north of the state of Paraná. A set of characters of diagnostic value: mouthparts, hind wing venation, binding patch, metendosternite, and details of male and female genitalia previously overlooked in the genus was provided. In addition to the morphological characterization, the molecular analyses of the COI mitochondrial gene and the ITS-1 rDNA nuclear region were included. The analysis of the ITS-1 nuclear region alone suggests proximity of D. wartensis to the Diabrotica fucata group, whereas molecular evidence based on combined analysis of COI and ITS-1 region suggest that this new species is distantly related to the Diabroticina with known sequences deposited in the GenBank.

A new species of gymnostome, Urotricha vitrea n. sp., is proposed. The morphological characterization of this new freshwater ciliate is as follows: 46–27 μm × 43–26 μm in size; a spherical macronucleus; 20–23 somatic kineties; a caudal cilium; brosse with 4, 3, 2 rows of pairs of kinetosomes; and circumoral infraciliature with 13–16 pairs of kinetosomes. In addition, the conjugation process of this species is reported. It includes three maturation divisions and three synkaryon divisions.

The genus Colaconema, containing endophytic algae associated with economically important macroalgae, is common around the world, but has rarely been reported in Taiwan. A new species, C. formosanum, was found attached to an economically important local macroalga, Sarcodia suae, in southern Taiwan. The new species was confirmed based on morphological observations and molecular analysis. Both the large subunit of ribulose-1,5-bisphosphate carboxylase/oxygenase (rbcL) and cytochrome c oxidase subunit I (COI-5P) genes showed high genetic variation between our sample and related species. Anatomical observations indicated that the new species presents asexual reproduction by monospores, cylindrical cells, irregularly branched filaments, a single pyrenoid, and single parietal plastids. Our research supports the taxonomic placement of C. formosanum within the genus Colaconema. This study presents the third record of the Colaconema genus in Taiwan.

This study contributes to the morphological characterization of Ombrophytum villamariensis, a new species of Neotropical Balanophoraceae recently described for Colombia. The study revealed the presence of diagnostic characters in the pollen grain such as small size and a circular endoaperture. Unlike other species, only tricolporate pollen grains were observed.
