Investigationof the species diversity of Coleoptera in Alborz Province (Coleoptera: Carabidae)

Abstract

Introduction: The aim of this study was to investigate species diversity of the ground beetles,
Carabidae Latreille, 1802 family in Alborz Province in three regions, including Karaj,
Eshtehard and Taleghan.
Materials & Methods: For this purpose, during 2016 and 2017, a total of 27 stations were
sampled using pitfall traps. The Shannon-Wiener index was calculated as an index of species
diversity.
Results: According to the results, a total of 329 ground beetles, including 36 species belonging
to 20 genera and 9 subfamilies were identified in the studied areas, which included 15 new
records for Alborz Province. The most dominant species in Karaj were Harpalus
(Pseudoophonus) griseus (Panzer, 1796), Harpalus (Pseudoophonus) rufipes (Degeer, 1774),
Harpalus (Harpalus) distinguendus distinguendus (Duftschmid, 1812) and Calathus
(Neocalathus) cinctus (Motschulsky, 1850). Zabrus (Zabrus) morio morio (Ménétriés, 1832)
and Grammognatha euphratica (Dejean, 1822) in Eshtehard and Ditomus calydonius oriens
(Dvořák, 1993), Calathus (Calathus) syriacus (Chaudoir, 1863) and Harpalus (Harpalus)
oblitus oblitus (Dejean, 1829) in Taleghan were dominant.
Conclusion: The results of the nonparametric biodiversity indices (Shannon-Wiener) showed
that Karaj had the highest species diversity.
