    https://doi.org/10.31396/Biodiv.Jour.2023.14.3.395.404

    ABSTRACT
    In this paper I present records of 105 species of grasshoppers and (bush) crickets observed in July-August 2022 at 69 localities throughout the country of Montenegro. With this a contribution to the biogeographical knowledge of the Orthoptera in Montenegro is aimed. Derived from the large dataset, species-richness is discussed based on the amount of species found at each locality and remarks are made on biodiversity hotspots. Commonness is treated and measured by the amount of localities each species is found. The most common species I order of presence are Pseudochorthippus parallellus, Euthystira brachyptera, Oedipoda caerulescens, Pachytrachis gracilis and Stenobothrus lineatus. Micropodisma salamandra is recorded for the first time in Montenegro and an undescribed species of Miramella was detected.
