Pešić: 27 September 2017 │ Published online: 29 September 2017. The insects from the order Psocoptera are poorly studied in Bulgaria (Lienhard & Smithers 2002). In this note I report of nineteen species of Psocoptera which were little known or were not recorded in this country. The study was carried out between 22.9.2016 and 27.8.2017 from seven geographic regions of Bulgaria (Fig. 1): Upper Thracian Lowland, Black Sea Coast, and the mountains of Sakar, Strandzha, Rhodopes, Pirin and Sarnena Gora. All specimens were collected and identified by the author. The barklice were searched by following methods: 1. Actively searched under tree bark and collected by hand; 2. Sieving with 1 mm mesh width sieve of detritus or crushed tree bark particles above white cloth; 3. Beating the vegetation above a sieve; 4. Checking for dead individuals in paddles, beneath windows and in spider webs; 5. Sweep netting of vegetation. Specimens were then over narcotized by diethyl ether, stored in ethanol or glycerin (when prepared on microscope slides), and after processing deposited in the collection of the author. Species identifications and taxonomy followed mainly Lienhard (1998). As supporting sources for some of the species also Saville (2008), Kučerová et al. (2014) and Yang et al. (2015) were used.
