A new species of Acartia (Copepoda, Calanoida) from the Philippines, based on morphological and molecular analyses

A new species of Acartia (Odontacartia), A. (O.) edentatasp. n., was collected from Leyte Island in the Philippines. Morphologically, the new species resembles A. (O.) pacifica Steuer, 1915. The female of the new species differs from other species of the A. (O.) erythraea Giesbrecht, 1889 species group in the absence of a pair of sharp spines on the posterior border of the genital double-somite and absence of setules on the lateral margins of urosomites 1–3. Unlike other congeners of the species group, males of the new species lack fine setules along the posterior margin of the prosome. Comparison of the new species with A. (O.) pacifica by pairwise distance data for the 16S (282 bp) gene indicates that these species differ by 20–21%, while the COI gene (636 bp) indicates a difference of 16–17%. The new species seems to be a coastal, occurring in warm waters having a salinity of 33.5.

A new species of the snapping shrimp genus Alpheus Fabricius, 1798 is described based on material from Galicia Bank, an offshore seamount off northwestern Spain. The type series of Alpheus gallicus n. sp. was collected at a depth of 768–785 m, making it one of the deepest occurring snapping shrimps. The new species belongs to the Alpheus macrocheles species group and is morphologically most similar to several deep-water members of this group, viz. A. lentiginosus Anker & Nizinski, 2011, A. platydactylus Coutière, 1897, A. romensky Burukovsky, 1990, as well as to the shallow-water A. macrocheles (Hailstone, 1835). The new species can be distinguished from all of them by some features on the minor cheliped and dactyli of the third to fifth pereiopods. In addition to morphology, DNA barcoding of the COI gene distinguished A. gallicus n. sp. from all related species with available barcode sequences.

Chaetostoma formosae sp. nov. is described from piedmont tributaries of the upper río Meta on the Cordillera Oriental in Colombia. The new species is distinguished from its congeners by the presence of an elongate unbranched anal-fin ray with two posterior dermal ridges in mature males, the presence of strongly recurved cheek odontodes, the presence of a parieto-supraoccipital dermal keel, the posterior margin of the pelvic-fin strongly projected and angulate in shape in mature males, and by details of coloration. The new species belongs to an informal monophyletic group herein called the Chaetostoma anale species group, along with two additional species, C. anale and C. jegui, from Colombia and Brazil respectively, based on an apomorphic modification of the anal fin in mature males.

A New Species

Examination of unidentified Phylliidae specimens revealed a number of undescribed species from the island of Luzon, Philippines. Morphological and molecular study of specimens from the obscure phasmid genus Microphyllium Zompro, 2001, revealed a new species, which we describe as Microphyllium haskelli Cumming sp. nov.. It is here described and differentiated from the two other species in the genus, both currently only known from adults of a single sex. Pseudomicrophyllium Cumming gen. nov. is described as a new genus within Phylliidae with the type species Pseudomicrophyllium faulkneri Cumming gen. et sp. nov. as the sole known species in the genus. As is unfortunately often the case in the leaf-mimicking family Phylliidae, this new genus and species is only known from a single specimen. In addition to the new genus, two new Phyllium (Phyllium) species from the siccifolium species-group are named and described as Ph. (Ph.) antonkozlovi Cumming sp. nov. and Ph. (Ph.) bourquei Cumming & Le Tirant sp. nov.. In addition to the newly described species, Phyllium (Phyllium) geryon Gray, 1843 is redescribed from a nearly perfect specimen, completing some of the morphological knowledge gaps currently missing because of the severely damaged holotype specimen. A key to all known species of Phylliidae from Luzon is included. Holotype specimens for all four new species will be deposited in the National Museum of the Philippines type collection and paratype specimens will be deposited into the San Diego Natural History Museum collection or retained within the first author’s collection.

Augustinus tuberculatus Huang, Yoshitake & Zhang, sp. n., is described from Guizhou Province, southwestern China. The species is readily distinguishable from its congeners by the prothorax having five pairs of tubercles in addition to paired median prominences. We classify the species into a new species group, the A. tuberculatus group, based mainly on the basally convex rostrum, elytral interval 1 with a velvety black scaly patch in the basal 1/3, interval 3 with a large obtuse tubercle in the middle (with 1–3 rows of setiferous granules), the posterior margin of ventrite 2 angularly produced in the middle and the anterior and posterior margins of ventrite 4 equidistant along their entire length. A key to the species groups of Augustinus is provided.

A New Species

The Western Balkans are an important hotspot of caddisfly diversity in Europe, with several microscale endemics, many of which were discovered during the recent years. The genus Potamophylax Wallengren, 1891 likely originated and diversified in Europe, with the Balkan Peninsula being one of the most important diversity hotspots. In this paper, we describe the new species Potamophylax coronavirus sp. n. from Bjeshkët e Nemuna National Park in the Republic of Kosovo. The new species belongs to the Potamophylax winneguthi species group and is morphologically most similar to Potamophylax juliani Kumanski, 1999, currently known only from Bulgaria and Potamophylax winneguthi Klapalek, 1902, known from Bosnia and Herzegovina and Serbia. The male of the new species differs from its most similar congeners mainly in exhibiting: (1) elongated subrectangular superior appendages in lateral view; (2) hardly acuminate, almost rounded apex of intermediate appendages; (3) differently shaped, irregular and higher inferior appendages; (4) narrow spinate area, roughly rectangular in dorsal view, slightly wider at the base and (5) different paramere shape and/or spine pattern. The new species also differs by its considerably smaller size and association with open, high altitude eucrenal zones. The uncorrected interspecific pairwise distance between P. coronavirus and other species of the P. winneguthi species group is on par with those amongst other recognised species in the group, as well as with the yet ambiguously identified taxa from the Sharr, Rila and Bajgorë Mountains. The new species is most probably a microendemic of Bjeshkët e Nemuna, thus highlighting further this area as an important hotspot of caddisfly biodiversity in Europe.

During a DNA barcoding campaign of leaf-mining Gracillariidae from the Asian part of Russia, a new species ofPhyllonorycterHübner, feeding on the Siberian pea shrub,CaraganaarborescensLam. (Fabaceae) was discovered in Siberia. Here, this taxon is described asPhyllonorycterivanisp. n.Among Fabaceae-feedingPhyllonorycter, so far onlyP.caraganella(Ermolaev) has been known to develop onCaragana.PhyllonorycterivaniandP.caraganellashow a large divergence in morphology (external and male genitalia) and barcode region of the mtDNA-COI gene (8.6%). They feed on different host plants species and have different ranges in Russia. We show that DNA barcode data weakly supports the Fabaceae-feeding species groups. In addition, we show that morphologically (strongly) and genetically (weakly),P.ivanihas affinity to thehaasispecies group, a West Palearctic group with asymmetrical male genitalia.
