Abstract Six new species of microcaddisflies (Trichoptera: Hydroptilidae) are herein described and illustrated: Cerasmatrichia armitagei sp. n., Metrichia hocica sp. n., Neotrichia majagua sp. n., N. solapa sp. n., Ochrotrichia latigiza sp. n., and O. ngabebuglea sp. n. These species were collected in western Panama from the Río Majagua watershed descending from Volcán Barú and Quebrada Martínez, a first-order stream in the Río Guabo watershed of the Bosque Protector Palo Seco. Metrichia quadrata (Flint, 1972) and Ochrotrichia filiforma Flint, 1972 are recorded for the first time from Panama. Two recently described species, Metrichia trebeki Harris and Armitage, 2019 and Ochrotrichia alma Thomson and Armitage, 2021 are reported for the second time from the country. The Republic of Panama now has 487 species of caddisflies distributed among 15 families and 56 genera. http://www.zoobank.org/urn:lsid:zoobank.org:pub:C98A88C2-2626-41E5-B294-0DBA6135AF67

Abstract We found significantly different percentages of malformed nymphs in two contiguous populations of Serratella ignita (Poda, 1761) in a stream in the northwestern Italy. We suggest that this may be due to a marked difference in the environmental conditions and especially to the effect of pollution on the functional structure of the insect community.

Abstract The embryonic development of Pantala flavescens (Fabricius, 1798) is documented for the first time. In contrast to previously reported insect embryonic development, we describe the embryological development of P. flavescens in living conditions by focusing on its externally recognisable features, i.e., we conducted the study in a purely non-destructive manner. The entire embryonic development was completed within six to seven days. We pictured the eggs at successive embryonic developmental stages: embryogenesis starts, germband formation, segmentation, blastokinesis, appendage formation, and dorsal closure. These findings can be helpful in future studies regarding the impacts of pollutants and climate change on the early embryonic development of dragonflies.

Abstract Climate change is increasing mean winter temperatures and the frequency of short-term high temperatures. Winter-emerging aquatic insects require an extended cold period to develop and may be negatively impacted by high winter air temperatures. Diamesa mendotae Muttkowski, 1915 is a cold-adapted, winter-emerging chironomid common in groundwater-dominated streams in Minnesota. Previous studies have found constant exposure to high air temperatures reduced adult D. mendotae survivorship, but not how short-term high temperature exposure may affect D. mendotae survivorship and reproduction. We found short-term exposure (24 or 48h) to 22 °C decreased adult D. mendotae longevity and reduced egg laying and larval hatch success, which may reduce future D. mendotae population sizes. Disruptions in D. mendotae and other cold-adapted insect populations may have broad ramifications for groundwater-fed stream ecosystems. Our study highlights the need for further research on cold-adapted insect survivorship after short-term winter temperature spikes to understand impacts of climate change beyond mean annual temperature increases.

Abstract Caenis limai sp. n. is described from the Veerapandi River in Theni, South India based on the larva, adult, and egg stages. The total number of Caenis species in India thereby is being augmented to eleven. The most closely related species to Caenis limai sp. n. is Caenis ulmeriana Malzacher, 2015 and the comparisons between both species are discussed herewith. The most important male subimaginal characters of Caenis americani Srinivasan et al., 2021 is described for the first time. http://www.zoobank.org/urn:lsid:zoobank.org:pub:8D25BB94-4B03-4360-9F67-E1CB58F2F982

Abstract The third-instar larva of Suphisellus curtus (Sharp, 1882) is described and illustrated for the first time, including morphometric and chaetotaxic analyses of the cephalic capsule, head appendages, legs, last abdominal segment, and urogomphus. This is the second detailed larval description for the genus Suphisellus Crotch, 1873. Larvae of this genus can be readily separated from other known noterid larvae by the strongly developed galea, subequal in length to maxillary palpus. Suphisellus curtus differs from S. rufipes (Sharp, 1882) in the dorsal colour pattern, S. rufipes being entirely testaceous and S. curtus testaceous with transverse brown bands between body segments.

Abstract A new species Acentrella (A.) isacki sp. n. is described based on the larvae collected from the Neeru stream of Jammu and Kashmir, India. It is the first record of the nominotypical subgenus Acentrella Bengtsson, 1912 from India. The new species does not belong to any Palearctic subgenus group proposed by Kluge and Novikova (2011). It is distinguished from closely related Acentrella (A.) lata (Müller-Liebenau, 1985) by the apico-internal projection on the labial palp segment II, sub-marginal arc of setae in labrum, and by the presence of spines on the inner margin of paraproct. http://www.zoobank.org/urn:lsid:zoobank.org:pub:992D271C-3327-4706-8625-7662CA4E2EF4

Abstract The population size of the diving beetle Cybister sugillatus Erichson 1834 (Coleoptera: Dytiscidae) has been declining in Japan; therefore, there is a need to understand their fundamental ecology for conservation purpose. Understanding the feeding habits in the larval stage will contribute to habitat restoration and ex situ conservation. In this study, we investigated the effects of the availability of different kinds of prey, such as Odonata nymphs and tadpoles, on larval growth of C. sugillatus. The results showed that Odonata nymphs were the preferred prey for larval growth because C. sugillatus larvae did not show significant growth on tadpoles alone. This trend was also observed in other Cybister species. Our results suggest that habitat restoration requires the development of an environment rich in a variety of aquatic invertebrates, including Odonata nymphs. In ex situ conservation, stable rearing and breeding of C. sugillatus can be made possible by providing them with Odonata nymphs as food.

Abstract The SDS–PAGE analysis of prey animals (fly larvae) during external digestion by aquatic predators, the larvae of selected species in dytiscid genera, showed a major component of protein with a molecular weight of ca. 20 kDa. In addition, the analysis of third instar larvae of Cybister brevis Aubé, 1838, by nanoLC–ESI–Q-TOF/MS/MS revealed that the digested body fluid includes a polypeptide with a sequence of 97 amino acids corresponding to hemocyanin N (51% matched by Mascot and BLAST searches) and hemocyanin M (12% matched) derived from flies. We also found evidence indicating that beetle larvae repeatedly release digestive enzymes at least twice while consuming the fly bodies. These results suggest that the digested polypeptides were derived from ubiquitous high molecular substances such as arylphorin subunit C223 precursor included in the body fluid of the fly (Calliphora vicina Robineau-Desvoidy, 1830) that were produced during external digestion by diving beetle larvae.

Abstract The vibrational duets of Nemoura lacustris Pictet, 1865 and N. flexuosa Aubert, 1949 are described from France. Nemoura lacustris communicates with a two-way duet having an ancestral signal pattern in which both male and female exhibit monophasic signals. Nemoura lexuosa has a more complex signal in which the male grouped call is composed by 2–4 repeated groups characterised by an increasing mean number of beats within successive groups and decreasing intergroup intervals. The female answer is composed of a variable repetition of beats usually with the three first intervals and the last one longer than others. An uncommon characteristic of the N. flexuosa call is the existence of a second male signal (reply or response) in the absence of the female answer. This reply is similar to the female answer, probably mimicking it and acting as a mate guarding tactic as previously proposed for the replies in other stoneflies by Boumans and Johnsen in 2015, or it could act stimulating the answer of potential female mates, but this should be confirmed.
