In the new species, striae are predominantly biseriate except for the central part of the valve, where they become uniseriate. Cymbella alexandrovichii sp. nov. is compared to 8 similar species of Cymbella that possess biseriate striae throughout the valve or only near the apices. Another species with biseriate striae— Gomphocymbellopsis guijiangensis — was included in the comparison based on the similar morphology. In addition, 3 species of Cymbella are compared to Cymbella alexandrovichii sp. nov. herein, despite lacking biseriate striation. The new species can be distinguished from similar taxa by a combination of features: asymmetric lanceolate outline with convex dorsal margin, not protracted cuneate to bluntly rounded valve ends, predominantly biseriate striae and 2–3 ventral stigmata.

title: Neststandort und Nestarchitektur der in leeren Schneckengehäusen nistenden Mauerbiene Osmia andrenoides (Hymenoptera, Megachilidae)

Entomo Helvetica 12: 57-68, DOI: 10.5169/seals-985861Abstract: Nesting site and nest architecture of the snail shell-nesting osmiine bee Osmia andrenoides (Hymenoptera, Megachilidae). − Osmia andrenoides Spinola, 1808 is a rare bee that nests in empty snail shells. To clarify aspects of its breeding biology, a dry rocky slope in the Domleschg (Grisons, Switzerland) was searched for nests of O. andrenoides in the fall of 2018. All 19 nests discovered were invariably hidden in (semi-)shady places under rock outcroppings or under large flat stones. They were built in shells of Zebrina detrita and contained 1–3 brood cells, which were separated from each other by thin walls built from chewed leaves («leaf pulp»). Nests were barricaded towards the opening with densely packed bits of earth, small stones and other particles. The nest closure at the shell opening consisted of two walls of leaf pulp, which enclosed a narrow interspace usually filled with a few bits of earth or small stones. Osmia andrenoides overwinters as a fully developed imago in a self-spun cocoon within the snail shells.Zusammenfassung: Osmia andrenoides Spinola, 1808 ist eine seltene Bienenart, die in leeren Schneckengehäusen nistet. Um offene Fragen ihrer Nistbiologie zu klären, wurde im Herbst 2018 an einem steinigen Trockenhang im Domleschg (Graubünden, Schweiz) nach Nestern von O. andrenoides gesucht. Die 19 entdeckten Nester lagen ausnahmslos gut geschützt an (halb)schattigen Stellen unter Stein- und Felsvorsprüngen oder unter Steinplatten. Sie befanden sich alle in Gehäusen von Zebrina detrita und enthielten 1–3 Brutzellen, die durch dünne Wände aus zerkautem Blattmaterial («Pflanzenmörtel») voneinander getrennt und gegen die Gehäusemündung zu mit angehäuften Erdbröckchen, Steinchen und anderen Fremdpartikeln verbarrikadiert waren. Der Nestverschluss an der Gehäusemündung bestand aus zwei dicht hintereinanderliegenden Abschlusswänden, die einen schmalen Zwischenraum einschlossen, der in der Regel mit wenigen Steinchen oder Erdbröckchen gefüllt war. Osmia andrenoides überwintert als voll entwickelte und ausgefärbte Imago in einem selbst gesponnenen Kokon im Innern der Schneckengehäuse.
