Hirschmanniella caudacrenaSher, 1968 intercepted in aquarium plants imported to Poland

Hirschmanniella caudacrena was detected in roots of aquarium plants imported from Thailand and Singapore to Poland. Morphology, morphometrics and diagnostic characters of the species are analyzed. It was shown that the ventral notch near the tail tip is a structure of two small symmetrical cuticular flaps. The significance of the tail tip structure to identify Hirschmanniella spp. pests is emphasized. Such detections indicate that aquarium plants imported from non‐European countries are an important pathway for entry to the EPPO region of the EU quarantine species of Hirschmanniella Luc & Goodey, 1963, other than H. gracilis (De Man, 1880), and deserve special attention from the plant quarantine services of EU member states.
