New species and records of Cloeodes Traver, 1938 (Ephemeroptera, Baetidae) from Costa Rica.

ABSTRACT: The nymph of Cloeodes danta sp. nov. is described from male and female nymphs collected from highland streams in the Caribbean Slope of the Costa Rica Central Volcanic Mountain Range. Adults are unknown. In addition, C. excogitatus and C. redactus are recorded for the first time in the country. Cloeodes danta sp. nov. can be differentiated from all described species by the predominantly brownish coloration on females and a similar coloration on males but with segments VII-IX light yellow and light brown, with no conspicuous marks or patterns; abundant scale-bases throughout most parts of the body; hindwings pads absent; the presence of three spines in the corners of the posterior margin of sternum III, and the posterior margin of tergum III with 28-30 spines on each side of the middle line (spine with a base width up to 0.5× spine length).

Distribution patterns include (1) species known only locally in Costa Rica or Colombia, (2) distributions connecting Central America to west Andes lowlands, and (3) north-west Neotropical components, extending from Central America to Brazilian Amazonia. The possible biogeographical and taxonomical context of Manota species with a widespread distribution is considered.

New species of Labiobaetis Novikova & Kluge from Southeast Asia and New Guinea (Ephemeroptera, Baetidae).

Project description:Material collected between 2006 and 2016 in Borneo, Sulawesi, and New Guinea further increased our knowledge of Labiobaetis Novikova & Kluge in these regions. Five species were previously reported from Borneo, two from Sulawesi, and 33 from New Guinea. Six new species have been identified using a combination of morphology and genetic distance (COI, Kimura 2-parameter), one species from Borneo (Brunei), one from Sulawesi, and four from New Guinea. They are described and illustrated based on their larvae and keys to the species of the relevant groups are provided. Additionally, new reports, a complementary description, and the COI sequence for L.dendrisetis Kaltenbach & Gattolliat are presented. The distribution of Labiobaetis in the Wallacea region is discussed based on the new findings. The total number of Labiobaetis species worldwide is augmented to 153.

Project description:The genus Symmerista Hübner (Notodontidae, Nystaleinae) is reviewed for Costa Rica, based on 49 wild-caught specimens. Four species are newly described: Symmerista luisdiegogomezi Chacón, Symmerista inbioi Chacón, Symmerista minaei Chacón and Symmerista aura Chacón. All are from the cloud forests of the Talamanca moutain range, southern Costa Rica. Photographs of the adults, male and female genitalia, and barcodes are also provided. The species Symmerista tlotzin Schaus (1892) is removed from Symmerista and assigned to the genus Elymiotis Walker as a new combination.

Initial commented checklist of Iranian mayflies, with new area records and description of Procloeon caspicum sp. n. (Insecta, Ephemeroptera, Baetidae).

Project description:An initial checklist of mayflies (Ephemeroptera) of Iran is compiled based on critical review of available literature data, complemented with new data from 38 localities of Gilan and Ardabil provinces. At present, altogether only 46 species and 25 genera are known from Iran, 18 species are reported as new to Iran in this study. Some previously published data are critically evaluated and doubtful taxa are excluded from the list. Basic analysis of the distribution and biogeography of recorded species is given. Procloeon (Pseudocentroptilum) caspicum Sroka, sp. n. is described based on mature larva and egg. Critical differential diagnostic characters distinguishing the species from related taxa are discussed in detail.

Two new species of the Hagnagora anicata complex (Geometridae, Larentiinae) from Costa Rica.

Project description:Examination of the lectotype (here designated) reveals that Hagnagora anicata (Felder & Rogenhofer) does not occur in Costa Rica. Instead two new species are described, Hagnagora eliannesp. n. and Hagnagora unniasp. n., and their distribution is discussed. The previous treatment of Hagnagora anicata as a single widespread species ranging from Jamaica and Mexico to Bolivia needs to be critically evaluated.

Rainforest and cloud forest Scolytodes (Curculionidae, Scolytinae, Hexacolini) from the Arthropods of La Selva inventory in Costa Rica: new species, new synonymy, new records.

Project description:Quantitative collecting efforts over the last several decades in Costa Rica have resulted in many new species of insects. The Arthropods of La Selva projects included collecting from a typical lowland Neotropical forest and up an altitudinal transect, and has provided many valuable samples of insects, spiders and mites potentially new to science. We describe 18 new species in the bark beetle genus Scolytodes Ferrari, 1867, 14 of which were collected during this project: S.angulus Jordal & Kirkendall, sp. nov., S.sufflatus Jordal & Kirkendall, sp. nov., S.squamatifrons Jordal & Kirkendall, sp. nov., S.comosus Jordal & Kirkendall, sp. nov., S.spatulatus Jordal & Kirkendall, sp. nov., S.seriatus Jordal & Kirkendall, sp. nov., S.profundus Jordal & Kirkendall, sp. nov., S.catinus Jordal & Kirkendall, sp. nov., S.fimbriatus Jordal & Kirkendall, sp. nov., S.sulcifrons Jordal & Kirkendall, sp. nov., S.planifrons Jordal & Kirkendall, sp. nov., S.porosus Jordal & Kirkendall, sp. nov., S.mundus Jordal & Kirkendall, sp. nov., S.callosus Jordal & Kirkendall, sp. nov., S.parvipilus Jordal & Kirkendall, sp. nov., S.plenus Jordal & Kirkendall, sp. nov., S.niger Jordal & Kirkendall, sp. nov., and S.simplex Jordal & Kirkendall, sp. nov. One species, Scolytodesminutissimus Schedl, 1952, is redescribed to match the holotype. We give new Costa Rica records for S.costabilis Wood, 1974, which is the correct name for S.obesus Wood, 1975 (syn. nov.). We report Costa Rica as a new country record for six species: Scolytodesclusiacolens Wood, 1967, S.crinalis Wood, 1978, S.culcitatus (Blandford, 1897), S.libidus Wood, 1978, S.reticulatus (Wood, 1961), and S.spadix (Blackman, 1943). From a closely related genus, we provide the first record for Central America (and only the second collection) of Pycnarthrumfulgidum Wood, 1977.
