A New Species

We describe a brackish-water calanoid copepod Acartia (Acanthacartia) cagayanensis sp. nov. collected from river estuaries in the northernmost Luzon, the Philippines. The new species has several characteristic features that are typical to the A. plumosa group (A. (A.) plumosa Scott T., 1894, A. (A.) sinjiensis Mori, 1940 and A. (A.) tropica Ueda & Hiromi, 1987); specifically, a short apical spine on the long terminal segment of male left leg 5, which is unique to the group. The morphological features of A. cagayanensis sp. nov. different from those of the A. plumosa group are the barrel-shaped genital double somite and the cylindrical basal part of the terminal segment of female leg 5. Among the species in the group, A. cagayanensis sp. nov. is closest to A. sinjiensis in terms of the spinule patterns on the female antennule, the posterior corner of the prosome, and the male second urosomite. The genetic analysis using DNA sequences of mitochondrial gene cytochrome oxidase subunit I (COI) revealed that A. sinjiensis from Japan and A. cagayanensis sp. nov. differed by 16.5–16.9%, in contrast to a small variation (0.0–0.5%) within each population. We confirmed that previous records of A. sinjiensis from the Philippines were not A. cagayanensis sp. nov., and therefore, A. cagayanensis sp. nov. is the third species of the subgenus Acanthacartia Steuer, 1925, after A. sinjiensis and A. (A.) tsuensis Ito, 1956.

The adult, larva, and pupa of Strepsicrates gattii Vargas-Ortiz & Vargas, sp. n. (Lepidoptera: Tortricidae: Olethreutinae: Eucosmini), are described and illustrated from the Atacama Desert of northern Chile. The larvae are leaf-tiers on the vulnerable native tree Morella pavonis (Myricaceae). As S. gattii was previously misidentified as S. smithiana Walsingham, morphological differences that enable the separation of the two species are highlighted. Sequences of the DNA barcode fragment of the cytochrome oxidase subunit I mitochondrial gene of the new species are provided and used in a Bayesian analysis with congeneric representatives to assess their relationships preliminarily. The divergence (K2P) with S. smithiana was 6.4–7.4%, providing additional support for separating the two species.

A New Species

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.

Marphysa Sanguinea

A new species of the Marphysa sanguinea group, M. iloiloensis n. sp. (Annelida: Eunicida: Eunicidae), is described from the Marine Annelids Hatchery of the Southeast Asian Fisheries Development Center, Aquaculture Department (SEAFDEC- AQD), Iloilo Province, Philippines. It represents the first record of this group in the Philippines. The new species is most similar morphologically to M. hongkongensa Wang, Zhang & Qiu, 2018, but can be distinguished from it by having fewer branchial filaments, a pair of faint eyes (absent in M. hongkongensa), and in slight differences in jaw morphology and chaetation. The embryos of the new species develop inside a jelly cocoon attached to the entrance of the adult burrow; this is the first time that egg-containing cocoons have been found in any species of the sanguinea-group. Phylogenetic analysis based on the mitochondrial gene cytochrome c oxidase subunit I (COI) revealed that Marphysa iloiloensis n. sp. is genetically distinct from all other analysed Marphysa species and forms a sister group to M. hongkongensa. A revised identification key to members of the sanguinea-group in Southeast Asia is provided.

A New Species

A new species of freshwater crab of the genus Geothelphusa, G. siasiat sp. nov., is described from Hsinchu and Miaoli counties, northwestern Taiwan. The new species can be distinguished morphologically from similar and geographically close species from western Taiwan by a suite of characters of the carapace, ambulatory legs, thoracic sternum, male abdomen, and male first pleopods. Comparisons of the DNA sequences encoding parts of the mitochondrial large subunit (16S) rRNA and cytochrome oxidase subunit I (COI) genes of specimens from western Taiwan further corroborate this finding. The opportunity is taken here to discuss the taxonomy of the poorly known species, Geothelphusa candidiensis Bott, 1967, based on a re-examination of the holotype, and the distribution of Geothelphusa species from western Taiwan. The report of G. siasiat sp. nov. brings the total number of species of Geothelphusa species known to 52.

AbstractMembers of the genusUvuliferare distributed worldwide and infect aquatic snails and freshwater fishes as first and second intermediate hosts, respectively, and fish-eating birds (kingfishers) as definitive hosts. Metacercariae ofUvuliferspp. were collected from the fins and skin of 20 species of freshwater fishes in Mexico, Guatemala, Honduras, Nicaragua and Costa Rica, and the adults were recovered from the intestine of kingfishers in four localities of Mexico. The genetic divergence among 76 samples (64 metacercariae and 12 adults) was estimated by sequencing the 28S and 5.8S nuclear genes, as well as the internal transcribed spacers ITS1 and ITS2, and one mitochondrial gene (cox1). Maximum likelihood and Bayesian inference analyses inferred with each dataset showed a high genetic diversity within the genusUvuliferacross Middle America, revealing the existence of four genetic lineages that exhibit some level of host specificity to their second intermediate hosts. The metacercariae of lineage 1 were associated with characids and cyprinids in central and northern Mexico. Metacercariae of lineages 2 and 3 were associated with cichlids distributed widely across Middle America. The lack of adults of these lineages in kingfishers, in lineages 2 and 3, or the fact that just a few adult specimens were recovered, as in lineage 1, prevented a formal description of these species. The metacercariae of lineage 4 were found in poeciliids, across a distribution range comprising Mexico, Guatemala, Honduras and Nicaragua, and the adult was found in the green kingfisher in Mexico. The number of specimens sampled for lineage 4, for both gravid adults and metacercariae, allowed us to describe a new species,Uvulifer spinatusn. sp. We describe the new species herein and we discuss briefly the genetic diversity inUvuliferspp. and the importance of using DNA sequences to properly characterize parasite diversity.

A New Species

A new species of the calanoid copepod, Pseudodiaptomus nansei sp. nov., which has formerly been identified as P. inopinus Burckhardt, 1913, is described from estuaries of the Nansei Islands, southernmost Japan. This new species was compared with a population of the closely related P. inopinus from the neighboring Kyushu Island, western Japan, which is redescribed here. The new species is readily distinguishable from P. inopinus by the absence of dorsal spiniform processes on the fifth pediger in both sexes, short posterior projections of the genital operculum, and thin caudal setae of the female instead of swollen seta in P. inopinus. The mitochondrial gene cytochrome oxidase subunit I (mtCOI) sequences of P. nansei differed by 21–26% from the examined population of P. inopinus, in contrast to a 0–3% difference within the population of each species. The absence of descriptions identifiable to P. nansei in previous studies outside the Nansei Islands, coupled with no occurrence of P. inopinus there, suggests that P. nansei is endemic to Nansei Islands and geographically segregated from P. inopinus.
