Monatractides stadleri

Monatractides stadleri (Walter, 1921) – complex (Fig. 8A) Published records: Montenegro: Pešić et al. (2021a), Zawal et al. (2020); Greece: Pešić et al. (2021b). Distribution: Western Palaearctic. New barcode sequences: Montenegro: BOLD:AED3802 (HYDMN403-24, HYDMN404-24, HYDMN413- 24, HYDMN050-24, HYDMN051-24, HYDMN068-24, HYDMN345-24, HYDMN346-24, HYDMN347-24, HYDMN357-24, HYDMN279-24, HYDMN191-24, HYDMN165-24, HYDMN215-24, HYDMN216-24). Greece: BOLD:AED3802 (BSNTN1956-24), BOLD:AGC6044 (BSNTN1921-24). BINs: BOLD:AED3802, BOLD:AGC6044. BIN distribution: BOLD:AED3802 (Montenegro, North Macedonia, Greece, Poland); BOLD:AGC6044 (Greece, Türkiye). Remarks. As emphasized Pešić & Smit (2023), genetic data revealed that European populations assigned to M. stadleri includes several distinct clusters, indicating the need for molecular and morphological re-definition of this species.
