Three new species of caddisflies (Trichoptera, Hydroptilidae, Polycentropodidae, Leptoceridae) from Khon Phapheng Waterfall, the Mekong River, Laos.

ABSTRACT: The Mekong River is a hotspot area for freshwater biodiversity, but caddisfly diversity is largely understudied. Three new species of caddisflies from three different families are described and illustrated from Khon Phapheng Waterfall, the Mekong River, Laos; Orthotrichiachoengthongi Malicky & Laudee, sp. nov. (Hydroptilidae), Pseudoneureclipsiskhonphaphengensis Malicky & Thamsenanupap, sp. nov. (Polycentropodidae), and Setodeskarrilai Malicky & Laudee, sp. nov. Orthotrichiachoengthongi Malicky & Laudee, sp. nov. can be differentiated from the most similar OrthotrichiatritonMalicky 2008 by the specific shape of segment X which is long and tubular, pointed apically and curved inward then immediately upward in dorsal view. Pseudoneureclipsiskhonphaphengensis Malicky & Thamsenanupap, sp. nov. differs from the similar P.kaineus Malicky & Bunlue in Malicky et al. 2004 by the shape of the inferior appendages that are usually broad, almost circular in lateral view. Setodeskarrilai Malicky & Laudee, sp. nov. is mainly different to S.omphale Malicky & Changthong in Malicky et al. 2004 by the distal part of segment X which has a brush-like process.

New species of caddisflies (Trichoptera, Ecnomidae, Polycentropodidae, Psychomyiidae) from Mekong tributaries, Laos.

Project description:Four new species of caddisflies are added to the fauna of Mekong River, Laos. Described and illustrated are Ecnomus petchanaae sp. nov. and E. boonsawaengae sp. nov. (Ecnomidae), Polyplectropus proukaewi sp. nov. (Polycentropodidae), and Psychomyia srichanai sp. nov. (Psychomyiidae) from tributaries of the Mekong River, Laos. Ecnomus petchanaae sp. nov. can be distinguished by the characters of the superior appendages, which are slender and club-shaped in lateral view. In E. boonsawaengae sp. nov., the inferior appendages are tubular with a concave incision subapically and truncated apex. Polyplectropus proukaewi sp. nov. has the distal process of the dorsal branch of the inferior appendage close to the base of the inferior appendages and the length of the process is half of inferior appendages. Psychomyia srichanai sp. nov. can be distinguished by the structure of the dorsal branches of the harpagones and apical sclerite. The outer branches of the harpago in the latter species are bifurcated and bent 90° degrees outward, and the inner dorsal branches of harpago are curved outward. The apical sclerite is indiscernible.

New <i>Cernotina</i> caddisflies from the Ecuadorian Amazon (Trichoptera: Polycentropodidae).

Project description:Two new species of the caddisfly genus Cernotina Ross, 1938 (Polycentropodidae) are described from the lowland Amazon basin of Ecuador, Cernotina tiputini, new species, and Cernotina waorani, new species. These represent the first new species described from this region. We also record from Ecuador for the first time Cernotina hastilis Flint, previously known from Tobago, and present new Ecuadorian locality records for C. cygnea Flint, and C. lobisomem Santos & Nessimian. The homology of the intermediate appendage of the male genitalia of this genus is established. The region surveyed is under severe environmental threat from logging, mining, and crude oil extraction, making the description of the biodiversity of the region imperative.

A new classification of the long-horned caddisflies (Trichoptera: Leptoceridae) based on molecular data.

Project description:BackgroundLeptoceridae are among the three largest families of Trichoptera (caddisflies). The current classification is founded on a phylogenetic work from the 1980's, based on morphological characters from adult males, i.e. wing venation, tibial spur formula and genital morphology. In order to get a new opinion about the relationships within the family, we undertook a molecular study of the family based on sequences from five genes, mitochondrial COI and the four nuclear genes CAD, EF-1α, IDH and POL.ResultsThe resulting phylogenetic hypotheses are more or less congruent with the morphologically based classification, with most genera and tribes recovered as monophyletic, but with some major differences. For monophyly of the two subfamilies Triplectidinae and Leptocerinae, one tribe of each was removed and elevated to subfamily status; however monophyly of some genera and tribes is in question. All clades except Leptocerinae, were stable across different analysis methods.ConclusionsWe elevate the tribes Grumichellini and Leptorussini to subfamily status, Grumichellinae and Leptorussinae, respectively. We also propose the synonymies of Ptochoecetis with Oecetis and Condocerus with Hudsonema.

Distribution of two rare taxa of caddisflies (Trichoptera: Rhyacophilidae, Polycentropodidae) from the Republic of Kosovo.

Project description:Background:The knowledge about distribution, ecology and species composition of caddisflies of the Balkan Peninsula is still not complete. The ongoing investigations of the last years highlight this area as an important hotspot of caddisfly diversity. Polycentropus ierapetra slovenica has been considered a narrow range endemic of Slovenia and surrounding areas. Rhyacophila aurata, a species known from many parts of Europe, according to the current knowledge, is absent from a large part of the Balkan Peninsula. New information:In this paper, we present records of these two rare taxa of Trichoptera from the Republic of Kosovo with exact distribution data, based on sampling carried out randomly during 2014 and 2017. Polycentropus ierapetra slovenica was found in several streams in Bjeshkët e Nemuna Mountains and Karadak Mountains. Rhyacophila aurata was found during this investigation at a single locality in Bjeshkët e Nemuna Mountains.The unexpected finding of these two taxa in Kosovo greatly enlarges their known distribution area and makes a contribution towards the better knowledge of distributional patterns of these rare taxa of caddisflies in this part of Europe.

The larva of Oecetistripunctata (Fabricius, 1793) (Trichoptera, Leptoceridae).

Project description:Oecetistripunctata is a widely distributed leptocerid in Europe, ranging from the Iberian and Apennine peninsulas and the Central and Western European highlands to the plains of Eastern Europe. The long, single-bladed mandibles are indicative for a predacious lifestyle. This paper describes the previously unknown larva of Oecetistripunctata. Information on the morphology of the 5th larval instar is given, and the most important diagnostic features are illustrated. A synoptic key for the European species of Oecetis is also provided. In the context of existing identification keys the larva of Oecetistripunctata keys together with Oecetisintima and Oecetisnotata. Oecetistripunctata is separated from the other two species by the fact that a double row of long setal fringes is lacking at the hind tibiae and that several long setae are present on the protrochantinus.

Project description:Four new species of Atanatolica Mosely are described from Ecuador: A.andina sp. n., A.angulata sp. n., A.curvata sp. n., and A.decouxi sp. n. These species belong to the A.dominicana group and constitute new records of the genus from Chimborazo, Imbabura, and Napo Provinces. Additionally, A.andina sp. n. represents the highest elevation recorded for any species in the genus at 3900 m. Size class data are also presented suggesting continuous larval growth for the probable larva of A.decouxi sp. n., described and illustrated here. A new distribution record is provided for A.manabi from Carchi Province.
