Structure and Evolution of the Antennal Sensory Surface in Endemic Caddisfly Tribes Baicalinini and Thamastini (Trichoptera: Apataniidae) from Lake Baikal

Diversity and distribution patterns of antennal sensilla in Hydropsychidae (Insecta, Trichoptera)

“…Thirdly, coronary sensilla have a wide variety of distribution pattern, which usually has no similarities even in closely related species from the same subfamily. Other types of sensilla, which have non-specific or specific distribution, display the same patterns in their localization as in other studied caddisfly families (Ivanov and Melnitsky, 2011;Melnitsky and Ivanov, 2016;Melnitsky et al, 2018;Valuyskiy et al, 2017Valuyskiy et al, , 2019Valuyskiy et al, , 2020aValuyskiy et al, , 2020b.…”

“…6C). Reduction of sensory fields was also found in two endemic tribes of Apataniidae (Valuyskiy et al, 2020b), where the number of curved trichoid sensilla is low on all segments. The great diversity of sensory fields' shape and their quantitative parameters in closely related species of Hydropsychinae and Macronematinae may indicate fast function-dependent evolution of antennal sensory surface in these groups.…”

“…Other sensilla types also show structural modifications: long trichoid, chaetoid, coronary, and styloconic sensilla. Coronary sensilla in Arctopsychinae, D. robus ta, D. gombak and D. hermione have unevenly deve loped microtrichia as in Rhyacophilidae (Valuyskiy et al, 2017), Ecnomidae (Valuyskiy et al, 2019), Glossosomatidae (Valuyskiy et al, 2020a) and Apataniidae (Valuyskiy et al, 2020b). D. gombak has two different subtypes of styloconic sensilla, as was noted in Philopotamidae (Melnitsky et al, 2018) and Plutellidae (Lepidoptera) (Yan et al, 2017).…”

“…At the same time, the diversity of sen-silla is much higher in basal Integripalpia: 13 types of sensilla were found in Rhyacophilidae, mostly based on mushroom-like pseudoplacoid sensilla modifications (Valuyskiy et al, 2017). The distribution and number of sensilla show a significant variety in more advanced families of Plenitentoria, as found in the family Apataniidae (Valuyskiy et al, 2020b). The data available for two previously studied species of Hydropsychidae, Hydropsyche newae and H. contubernalis, are quite scarce (Melnitsky and Ivanov, 2011;Ivanov and Melnitsky, 2016).…”

A unified dataset of colocated sewage pollution, periphyton, and benthic macroinvertebrate community and food web structure from Lake Baikal (Siberia)

“…Leeches were enumerated at the subclass level, but were likely all from the family Glossiphoniidae based on size, depth of sampling locations, and invertebrate communities sampled (Kaygorodova 2012). Like mollusks, caddisflies were also enumerated at the order level, although Baikal does contain over 14 species of caddisfly (Valuyskiy et al 2020). Flatworms were enumerated at the phylum level.…”
