The genus Poecilimon includes 142 species divided into 18 groups. It is distributed throughout the Palaearctic area. One of the groups is the Poecilimon ornatus group, in which many closely related taxa have been identified (13 species). Although several searches have been carried out, the phylogeny and systematics of P. ornatus are only partly resolved. The most dispersed taxon within the group is Poecilimon affinis, having numerous subspecies. Species from the P. ornatus group have been described mainly based on morphological characteristics, as well as type of song. The aim of this study is to clarify the relationships between species from the P. ornatus group by comparing partial sequences of the cytochrome c oxidase subunit I (COI) mitochondrial gene. The analyses were carried out on 84 specimens from 23 taxa. Bush-crickets from the P. ornatus group are monophyletic, in contrast to taxa within the P. affinis complex. Not all of the previously described divisions of the group based on morphology, bioacoustics, distribution, and ecology were confirmed.

Isostenosmylus Krüger, 1913 is the richest genus of Osmylidae of the Neotropical region, with 17 described species so far, which are distributed mainly in the Andean region and in the South of Brazil and Paraguay. A new remarkable Colombian species of Isostenosmylus—I. ammirabilis sp. nov.—is herein described and illustrated. DNA barcode of mitochondrial gene cytochrome c oxidase subunit I (COI) for this species is also provided. Taxonomic keys for the genus are updated.

Living representatives of the Neotropical genus Choeradoplana Graff, 1896 (Geoplaninae, Tricladida, Platyhelminthes) are easily recognized by the typical shape of the head which is laterally expanded, rolled-up, and ventrally provided with two glandular cushions. In this study, the morphology and phylogeny (cytochrome C oxidase subunit I gene) of several species of land planarians are taxonomically investigated. Four of the six species studied are new to science, namely: Ch. eudoxiae Silva & Carbayo, sp. nov., Ch. claudioi Lago-Barcia & Carbayo, sp. nov., Ch. onae Lago-Barcia & Carbayo, sp. nov., and Ch. riutortae Lago-Barcia & Carbayo, sp. nov. The species Choeradoplana albonigra and Ch. eudoxiae deviate from the usual body shape pattern in that the head does not present lateral expansions nor glandular cushions, becoming indistinguishable from its sister genus Cephaloflexa. Pseudogeoplana tristriata (Schultze & Müller, 1857) is also redescribed from a newly collected specimen and was discovered to be a member of Choeradoplana. Graff (1899) also studied another specimen that was considered to be conspecific with P. tristriata; however, in this new it is concluded that it is not conspecific but rather a new species. The name Pseudogeoplana aevipandemiae Lago-Barcia & Carbayo, sp. nov. is suggested for Graff’s specimen.

Abstract Background: In microscopical examinations of stool samples, S. stercoralis may be miss-diagnosed with other nematodes infecting human digestive system, especially Rhabditis species that release larvae in stool samples. The aim of this study was molecular characterization and differentiation of human derived isolates of S. stercoralis and Rhabditis species based on the mitochondrial gene of cytochrome c oxidase subunit 1 (cox1) amplification. Methods: Using parasitological methods, ten isolates of S. stercoralis and three isolates of Rhabditis spp. were obtained from fresh stool samples of patients and the genomic DNA of the samples were extracted. PCR amplification of cox1 gene was carried out for all the isolates and the products were sequenced. Results: The phylogenetic analysis illustrated that S. stercoralis and Rhabditis spp. isolates were placed in two distinguishable separate clades. Inter-species genetic variation between isolates of S. stercoralis and Rhabditis spp. were ranged from 13.5 to 14.5%. Conclusions: Cox1 gene was a suitable marker for discrimination of S. stercoralis from Rhabditis spp. retrieved from human in the current study.

Decamyia Dyar is a subgenus of Wyeomyia Theobald with three valid species. Wyeomyia rorotai Senevet, Chabelard & Abonnenc, a species originally described rather briefly in the subgenus Dendromyia, is without subgeneric position in the genus. In the present work, we redescribe Wy. rorotai in all life stages and formally define its taxonomic placement in the subgenus Decamyia by combining morphological and molecular analyses based on the mitochondrial cytochrome c oxidase subunit I gene. We also show that Decamyia is a rather homogeneous group of four species, i.e. Wy. ulocoma (Theobald), Wy. pseudopecten Dyar & Knab, Wy. felicia Dyar & Núñez Tovar and Wy. rorotai, the immature stages of which almost exclusively inhabit the flower bracts of Heliconiaceae.
