Genus Synurella Wrześniowski, 1877 Synurella Wrześniowski, 1877: 403. Goplana Wrześniowski, 1879: 299. Boruta Wrześniowski, 1888: 44. Eosynurella Martynov, 1931: 531. Diasynurella Behning, 1940: 43. Type species Gammarus ambulans F. Müller, 1846 (= Synurella ambulans (F. Müller, 1846) designated by Wrześniowski (1877)). Revised diagnosis (related to sub-family group 1 sensu Bousfield 1977: 302) Closely allied with Stygobromus Cope, 1872, but with the following characteristic features: head, lateral cephalic lobe broadly rounded without inferior sinus (except Synurella osellai ); antenna 2 of male with paddle-shaped calceoli; gnathopod 1 propodi sub-quadrate; gnathopod 2 propodi with well-developed posterior margins, propodi always larger than the same of gnathopod 1; coxal plates 1–3 deep, much longer than broad; coxal plate 4 deep, with excavation; urosomites partially or entirely fused; telson apical margin distinctly notched or lobate; oöstegites 2–5 large, ovoid. Remarks In our opinion, the Crimean form Synurella ambulans taurica Martynov, 1931, with a slightly extended basipodite of pereopod 7, is related to the southern species complex of S. intermedia and S. tenebrarum rather than to the nominative species. However, owing to the poor description it is difficult to reach a definite conclusion. : Published as part of Sidorov, Dmitry, Palatov, Dmitry & Ras, Institute of Biology and Soil Science Feb, 2012, Taxonomy of the spring dwelling amphipod Synurella ambulans (Crustacea: Crangonyctidae) in West Russia: with notes on its distribution and ecology, pp. 1-19 in European Journal of Taxonomy 23 on pages 4-5, DOI: 10.5852/ejt.2012.23, http://zenodo.org/record/3858323 : {"references": ["Martynov A. 1931.
