Abstract

This paper presents the first record of Luticola vanheurckii Van de Vijver & Levkov, outside of the type locality (second record in the Europe). Authors present habitat characteristic of the species, with LM and SEM micrographs. Luticola vanheurckii was found in a small outflow of water from storm sewers in Stalowa Wola (SE Poland). Luticola vanheurckii occurred only rarely (0–5 valves per slide), in a small, shallow puddle which was supplied by the water from the outflow. This species was recorded in sediments and on plants submerged in water with a wide range of conductivity (347–22,100 μS cm−1), chloride content (64.56–6195.0 mg l−1) and sodium ions (43.04–3789.1 mg l−1). The cells observed in the examined material were slightly longer and wider than those from type locality.

Highlights

Luticola is a large, widespread genus with around 200 different species
Species of the genus Luticola were included in the genus Navicula, but due to differences in nearly every aspect of the morphology and cell organization, they were displaced into a new genus, with the type species is Luticola mutica D.G
The habitat of Luticola vanheurckii in the city of Stalowa Wola was characterized by a very high electrolyte content (13250–22,100 μS cm−1), especially during the period when water stopped flowing

Summary

Introduction

Widespread genus with around 200 different species. Species of the genus Luticola were included in the genus Navicula, but due to differences in nearly every aspect of the morphology and cell organization, they were displaced into a new genus, with the type species is Luticola mutica D.G. Mann. Several occurrences of Luticola species came from territory of Poland 2003; Wojtal 2009; Bąk et al 2012). Thirteen taxa of this genus have been identified so far within the Subcarpathian province (Noga et al 2014; Noga et al 2017)
