Abstract: Life history of benthic faunas of tropical high-altitude cold environments are poorly studied. Here, monthly larval and adult data are presented for Anomalocosmoecus illiesi at Saltana Stream in Ecuador. In cold conditions throughout the year (6 °C), this species showed an asynchronous and continuous production. Larval density showed two peaks in August and April. All five larval instars were present in most months. Using the size-frequency method an annual rate of secondary production per biomass of 4.8 was calculated. The measured biomass was 785 mg/m2.

The larva of Drusus dudor Oláh, 2017, including an updated key to larval Drusinae Banks, 1916 (Insecta, Trichoptera, Limnephilidae) https://zookeys.pensoft.net/article/47032/ ZooKeys 908: 137-155

DOI: 10.3897/zookeys.908.47032

Authors: Simon Vitecek, Jan Martini, Carina Zittra, Hendrik Kuhlmann, Ariane Vieira, Johann Waringer

Abstract: The caddisfly Drusus dudor Oláh, 2017 (Limephilidae: Drusinae) was described from the Northwestern Italian Alps. We provide a detailed description of the larva, based on material from the Italian Province of Piemonte. Information on the morphology of the 5th larval instar is given, and the most important diagnostic features are illustrated. The larva is included in an updated key to larval Drusinae where D. dudor keys together with Drusus aprutiensis Moretti, 1981, D. camerinus Moretti, 1981, D. croaticus Marinkovic-Gospodnetic, 1971, D. mixtus (Pictet, 1834), and D. nigrescens Meyer-Duer, 1875. The species can be reliably separated by the morphology of the pronotum, the shape of the metanotal sclerites, and by morphological details of abdominal sternum I.

The larvae of the European species of genus Apataniana Mosely, 1936 (Trichoptera, Apataniidae): descriptions, key and ecology https://zookeys.pensoft.net/article/7758/ ZooKeys 586: 121-134

DOI: 10.3897/zookeys.586.7758

Authors: Johann Waringer, Hans Malicky

Abstract: This paper describes the previously unknown or insufficiently known larvae of Apataniana hellenica, Apataniana stropones and Apataniana vardusia. Species association was enabled by the fact that the three micro-endemic Apataniana larvae are restricted to Greece and the only Apataniidae species recorded in European ecoregion 6 (Hellenic Western Balkan; Graf et al. 2008), and that the endemic status of the three species clearly defined their non-overlapping sampling ranges. Information on the morphology of the larvae is given, and the most important diagnostic features are illustrated.

Description of two new filtering carnivore Drusus species (Limnephilidae, Drusinae) from the Western Balkans https://zookeys.pensoft.net/article/5689/ ZooKeys 513: 79-104

DOI: 10.3897/zookeys.513.9908

Authors: Simon Vitecek, Mladen Kučinić, János Oláh, Ana Previšić, Miklós Bálint, Lujza Keresztes, Johann Waringer, Steffen Pauls, Wolfram Graf

Abstract: Two new species of the genus Drusus (Trichoptera, Limnephilidae, Drusinae) from the Western Balkans are described. Additionally, observations on the biodiversity and threats to the region’s endemic aquatic fauna are discussed. Drusus krpachi sp. n. is a micro-endemic of the Korab Mountains, Macedonia, and D. malickyi sp. n. is a micro-endemic of the Prokletije Mountains, Albania. Both new species are most similar to D. macedonicus but differ from the latter in the shape of segment IX, the shape of the tips of the intermediate appendages in lateral view, the shape of the inferior appendages, and the form and shape of the parameres. In addition, males of the European species of filtering carnivore Drusinae are diagnosed and illustrated, including Cryptothrix nebulicola McLachlan, Drusus chrysotus Rambur, D. discolor Rambur, D. macedonicus Schmid, D. meridionalis Kumanski, D. muelleri McLachlan, D. romanicus Murgoci and Botosaneanu, and D. siveci Malicky. These additions to the Western Balkan fauna demonstrate the significance of this region for European biodiversity and further highlight the importance of faunistic studies in Europe.

Description of a new species of Wormaldia from Sardinia and a new Drusus species from the Western Balkans (Trichoptera, Philopotamidae, Limnephilidae) https://zookeys.pensoft.net/article/5113/ ZooKeys 496: 85-103

DOI: 10.3897/zookeys.496.9169

Authors: Simon Vitecek, Ana Previšić, Mladen Kučinić, Miklós Bálint, Lujza Keresztes, Johann Waringer, Steffen Pauls, Hans Malicky, Wolfram Graf

Abstract: New species are described in the genera Wormaldia (Trichoptera, Philopotamidae) and Drusus (Trichoptera, Limnephilidae, Drusinae). Additionally, the larva of the new species Drusus crenophylax sp. n. is described, and a key provided to larval Drusus species of the bosnicus-group, in which the new species belongs. Observations on the threats to regional freshwater biodiversity and caddisfly endemism are discussed. The new species Wormaldia sarda sp. n. is an endemic of the Tyrrhenian island of Sardinia and differs most conspicuously from its congeners in the shape of segment X, which is trilobate in lateral view. The new species Drusus crenophylax sp. n. is a micro-endemic of the Western Balkans, and increases the endemism rate of Balkan Drusinae to 79% of 39 species. Compared to other Western Balkan Drusus, males of the new species are morphologically most similar to D. discophorus Radovanovic and D. vernonensis Malicky, but differ in the shape of superior and intermediate appendages. The females of D. crenophylax sp. n. are most similar to those of D. vernonensis, but differ distinctly in the outline of segment X. Larvae of D. crenophylax sp. n. exhibit toothless mandibles, indicating a scraping grazing-feeding ecology.

Chaetopteryx bucari sp. n., a new species from the Chaetopteryx rugulosa group from Croatia (Insecta, Trichoptera, Limnephilidae) with molecular, taxonomic and ecological notes on the group https://zookeys.pensoft.net/article/3482/ ZooKeys 320: 1-28

DOI: 10.3897/zookeys.320.4565

Authors: Mladen Kučinić, Ildiko Szivak, Steffen Pauls, Miklos Balint, Antun Delić, Ivan Vučković

Abstract: We describe a new autumnal caddisfly species Chaetopteryx bucari sp. n. from 8 localities in the Banovina region of Croatia. We also present molecular, taxonomic and ecological notes (emergence, sex ratio and seasonal dynamics) on the new species and discuss the distribution of Chaetopteryx species in general and the C. rugulosa group in particular. Based on Bayesian phylogenetic analysis C. rugulosa schmidi was separated from the clade containing the other subspecies of C. rugulosa. Thus the subspecies C. r. schmidi is here raised to species level, C. schmidi, as it was described originally. We further present distribution data on rare species in the genus Chaetopteryx in Croatia.

The larva of Drusus vinconi Sipahiler, 1992 (Trichoptera, Limnephilidae, Drusinae) https://zookeys.pensoft.net/article/3358/ ZooKeys 317: 69-80

DOI: 10.3897/zookeys.317.5749

Authors: Johann Waringer, Wolfram Graf, Miklós Bálint, Mladen Kučinić, Steffen Pauls, Ana Previšić, Lujza Ujvárosi, Simon Vitecek

Abstract: This paper describes the previously unknown larva of Drusus vinconi Sipahiler, 1992. Information on the morphology of the 5th larval instar is given, and the most important diagnostic features are illustrated. In the context of existing identification keys the larva of D. vinconi keys together with D. annulatus (Stephens, 1837), D. biguttatus (Pictet, 1834), D. ingridae Sipahiler, 1993, Hadimina torosensis Sipahiler, 2002 and Leptodrusus budtzi (Ulmer, 1913). These species differ in the contours of the pronotum in lateral view, the presence/absence of the pronotal transverse groove, the shape of the median notch of the pronotum (in anterior view), pronotal sculpturing, presence/absence of the lateral carina of the head capsule, the number of proximo-dorsal setae on the mid-and hind femora, where the lateral fringe starts on the abdomen, and in geographic distribution. With respect to zoogeography, Drusus vinconi is a (micro-)endemic of the Western Pyrenees. The species prefers stony substratum in springs and springbrooks of the montane and subalpine region (Graf et al. 2008; Sipahiler 1992, 1993). As a grazer, the larvae of D. vinconi feed on biofilm and epilithic algae.
