Ruicănescu, Adrian, Dumbravă, Amalia-Raluca & Drăghici, Andreea-Cătălina, 2022, Capnodis cariosa (Pallas, 1776) found in a new Romanian location at the northern limit of its distribution range (Coleoptera: Buprestidae), Fragmenta entomologica 54 (1), pp. 155-158 : 155-156

Capnodis cariosa cariosa (Pallas, 1776)

Diagnosis. Length, 18–35 mm. The body colour is black. The pronotum is covered with white wax, except the smooth impressions. Elytra are black with white, waxy spots.

Biology & ecology. Capnodis cariosa develops in Anacardiaceae , such as the Pistachio tree ( Pistacia vera ), in southern Europe its main host plants being usually represented by Pistacia lentiscus and P. terebinthus .

In Romania, it develops in the roots and necks of the smoke tree, Cotinus coggygria ( Fig. 1 ). The larval stage lasts about 1-2 years, depending on the food quality and the climatic conditions. The adults live about one year, sometimes surviving until the next year. They can be found on the host plants ( Fig. 2 ). Capnodis cariosa prefers xero-thermophilic woods, plantations or shrubs, mostly on sunny slopes.

Distribution. The species (thus including the nominate subspecies and C. cariosa hauseri Obenberger, 1928 from the Near East) is distributed in Northern-Mediterranean and Irano-Anatolian areas, from Sardinia westwards to the Near East eastwards (GBIF.org 2021; Löbl & Löbl 2016; Fig. 4 ) 1. The northernmost known location is in the Krasnodar Region (SW Russia) ( Volkovitsh 2018). In Romania, Capnodis cariosa were previously recorded only from the southern Dobrudja (Oltina, Canaraua Fetii, CărpiniȘ-Băneasa-Adamclisi, Constanța County) ( Negru et RoȘca 1967; Ruicănescu 2013; Panin et al. 2015).
