# Triploid female Helophorusbrevipalpis Bedel, 1881 in Provence, France, with additional data on C-banding in both triploid and diploid material, and discussion of chromosomal variation in H.brevipalpis

## TL;DR

This paper reports triploid female Helophorus brevipalpis in France and compares their karyotypes with those from Spain and Italy.

## Contribution

The study provides new karyotype data for triploid H. brevipalpis in France and compares chromosomal variation across regions.

## Key findings

- Triploid H. brevipalpis in France have karyotypes similar to Spanish samples but with minor differences from Italian ones.
- C-banding patterns in English H. brevipalpis are documented for the first time.
- Chromosomal variation in H. brevipalpis is discussed based on comparative data.

## Abstract

Triploid female Helophorusbrevipalpis Bedel, 1881 are recorded from two localities in Provence, France. Their karyotypes are analysed using both chromosome morphology and C-banding. Their karyotypes appear to be identical with those of Spanish material recorded by Angus (1992) but show minor differences from Italian triploid material described by Angus, Jia (2020). Data on C-banding in English H.brevipalpis are given and chromosomal variation in H.brevipalpis is discussed.
