Discovery of the diving beetle Laccornis oblongus (Stephens, 1835) in Bavaria, southern Germany (Coleoptera, Dytiscidae, Hydroporinae, Laccornini)

The diving beetle Laccornis oblongus (Stephens, 1835) is recorded for the first time from Bavaria, southern Germany, which marks the most south-westerly record of the species known to date. Three specimens were collected in the Murnauer Moos nature reserve in Upper Bavaria. We summarize what is known about the species habitat in Germany and provide photographs of the sampling site and habitus, median lobe of aedeagus, and paramere of the species. We provide a checklist of the 20 other diving beetle species we found syntopic with L. oblongus. 

New records of fungal pathogens of invertebrates from endemic pine forests in Mexico

We report fungal pathogens of invertebrates (FPI) (Entomophthorales, Hypocreales, and Orbiliales) from roots of an endemic Mexican pine, Pinus greggii Engelm. ex Parl., at four primary montane forests using next-generation sequencing. We found twenty-nine OTUs from 18 genera of FPI associated to the roots of P. greggii. New records for Mexico are: Beauveria felina (DC.) J.W.Carmich., Dactylella mammillata S.M. Dixon, Dactylella ramosa Matsushima, Drechslerella brochopaga (Drechsler) M. Scholler, Hagedorn & A. Rubner, Hirsutella minnesotensis Chen, Liu & Chen, Leptobacillium leptobactrum (W.Gams) Zare & W.Gams, Metapochonia variabilis Z.F.Zhang, F.Liu & L.Cai, Monacrosporium leptosporum (Drechsler) A. Rubner, and Simplicillium aogashimaense Nonaka, Kaifuchi & Masuma. A largely unknown array of fungal pathogens of invertebrates are likely to be found in Mexican forests.  This work facilitates future analyses of fungal diversity in these primary forests, as well as basic and applied research in biological control.

First records and range extension of Bristle-spined Porcupine, Chaetomys subspinosus (Olfers, 1818) (Rodentia, Erethizontidae), in Minas Gerais state, Brazil

We report from three localities four new records of the threatened Brazilian Atlantic Forest endemic Chaetomys subspinosus (Olfers, 1818). These are the first records of this porcupine species from the state of Minas Gerais, and these new data extend the distribution of this species by approximately 220 km to the southwest. As C. subspinosus was observed in areas of transitional vegetation, this species may be found in a much broader spectrum of habitat types than previously thought. We recommend further surveys focusing on documenting this species.

Bird species inventory in secondary tropical montane cloud forest at Cloudbridge Nature Reserve, Talamanca Mountains, Costa Rica

The tropical montane cloud forests (TMCF) of the Talamanca Mountains of Costa Rica are a unique and understudied habitat that is home to a high number of endemic bird species. Cloudbridge Nature Reserve is a TMCF reforestation reserve lying on the Pacific slope of Cerro Chirripó in the cantón of Pérez Zeledón. Here, we synthesize data collected at Cloudbridge between March 2016 and May 2020 from multi-year point count, walking, call-playback, and camera trap surveys along with photographs collected from February 2007 to April 2021 to present a bird species inventory of the reserve. In total, 204 bird species from 40 families, including 40 endemic species, were identified, and monthly presence summarized for each species. We discuss the implications of our findings for understanding TMCF avian communities, as well as the importance of year-round surveys using a variety of techniques to better capture overall avian diversity.

New record of Hypselodoris infucata (Rüppell & Leuckart, 1830) (Mollusca, Gastropoda, Chromodorididae) in the Republic of Mauritius

To date, 179 species belonging to the gastropod infraclass Euthyneura are known from Mauritius. We report for the first time from Mauritius the chromodorid nudibranch, Hypselodoris infucata (Rüppell & Leuckart, 1830), based on 47 sites surveyed over 17 months. This species was previously known from the eastern Mediterranean Sea, Indo-Pacific Ocean, and Western Indian Ocean. We observed it in Mauritius at Bain des Dames near a shipwreck under coral rubble. Considering the small size and camouflage behavior of some nudibranch species, additional fieldwork will likely add others species unknown from the islands.

Phaeosphaeria deschampsii J. Putzke & A.B.Pereira (Ascomycota, Fungi) causing whitening in Deschampsia antarctica Desv. (Poaceae) in the South Shetland Islands

Phaeosphaeria deschampsii was described from dead leaves of Deschampsia antarctica (Antarctic Grass). We surveyed other islands of the South Shetland archipelago, Antarctica, and also found Arctic Grass whitening, the disease associated with this fungus, indicating that is disease is widespread.

Bat diversity from an area of coastal Atlantic Forest in southeastern Brazil

We characterize the bat fauna of forested sites in the municipality of Domingos Martins, Espírito Santo state, southeastern Brazil, and update the list of bat species of the state. We conducted a rapid inventory using ground-level mist nets (27,000 m²·h effort) and occasional roost searching, which resulted in a list of 23 species belonging to Phyllostomidae (18 species), Vespertilionidae (3), and Molossidae (2). We report the first record of Molossops neglectus Williams & Genoways, 1980 and Myotis lavali Moratelli, Peracchi, Dias & Oliveira, 2011 from Espírito Santo, bringing the total number of confirmed species in the state to 86. The molossid Nyctinomops laticaudatus (É. Geoffroy, 1805) was exclusively recorded in its diurnal roost in rocky outcrops. Our study fills knowledge gaps in the distribution of bat species in southeastern Brazil, and more specifically in the highly diverse coastal Atlantic Forest of Espírito Santo. These data reinforce the importance of continuously inventorying and documenting bats in the Neotropics.

A new locality for the rare Guerreran Centipede Snake, Tantilla coronadoi Hartweg, 1944 (Squamata, Colubridae), with comments on morphological variation

We record the third known specimen of Tantilla coronadoi Hartweg, 1944 from Guerrero, Mexico. Our new record extends this species’ distribution by 90 km and to a new Mexican biogeographic province (Balsas Basin). The morphological similarity between this and the two previously known specimens supports the validity of the taxon, and otherwise points to the possible presence of an undescribed taxon on the coast of Guerrero. Additional fieldwork yielding a larger series of this and other infrequently encountered species may enable a better understanding of their distribution, natural history, ecology, and conservation.

An annotated checklist of vascular plants in and around two major high-altitude wetlands of Lahaul-Spiti, Himachal Pradesh, India

We document for the first time the diversity of vascular plants of Chandra Tal and Suraj Tal, two high-altitude wetlands (HAWs) spanning the cold desert region of Lahaul-Spiti, showing the occurrence of 188 species and one variety distributed among 97 genera and 29 families. Only one species, Ephedra intermedia Schrenk & C.A. Mey. is a gymnosperm, and the other 187 species are angiosperms. Of the angiosperms, Asteraceae is the dominant family, consisting of 27 species and one variety in 17 genera. Among the species, six are classified as threatened, 17 species are native, and two species (Eritrichium nanum (L.) Gaudin and Ranunculus trivedii Aswal & Mehrotra) are endemic to the Himalayan region. We provide baseline data for future research on the floristic diversity of two major HAWs of Lahaul-Spiti. We also highlight the importance of HAWs for the conservation of species.

Fishes of the Mfimi River in the central Congo basin of the Democratic Republic of Congo. Kasai ecoregion or part of the Cuvette Centrale?

Despite the cultural and economic importance of fisheries to communities in the region, the Mfimi is one of the least well-documented river systems in the central Congo basin. Here we present a preliminary listing of species collected during two surveys sampling 35 sites along the main channel, in major tributaries, and in some marginal habitats. A total of 2195 specimens representing 141 species were collected and archived at the American Museum of Natural History, New York, and in the teaching collections of the University of Kinshasa. Five species are considered as potentially new to science, and range extensions of numerous species into the Mfimi are recorded. Based on the data presented we conclude that the fish communities in the Mfimi share affinities with those of the Cuvette Centrale to the north, rather than the Kasai basin with which the river is currently connected via an inflow at the Kwa-Kasai junction.
