03D6BB11CE628567FE74FC667242F96F.taxon	biology_ecology	Hosts / Substrates — On moss, litter under Juniperus spp. (Cupressaceae), Thymus spp. (Lamiaceae), Achillea spp. (Asteraceae), Androsace spp. (Primulaceae), Poaceae, Senecio spp. (Asteraceae), unidentified plant (Papadoulis et al. 2009), humus, soil, Hyparrhenia hirta (L.) Stapf. (Poaceae) (Demite et al. 2022). Previously, in Romania A. meridionalis was reported from moss samples (bark moss, rock moss and soil moss) taken from mature (over 80 years) natural forests located between 378 and 1445 m a. s. l. (Manu et al. 2018 a).	en	CălugărK, Adina, StathakisK, Theodoros, Papadoulis, Georgios Th.

03D6BB11CE628567FE74FC667242F96F.taxon	discussion	Remarks — Although A. meridionalis is mentioned as resistant to dry habitats such as agro-ecosystems, dunes or inland meadows (Manu et al. 2018 b), in our study it was found only in forest ecosystems. Morphological characters of the examined specimens fit well with those of the redescription of Döker et al. (2020). At Romanian specimens of A. meridionalis fixed digit have four teeth (three of them are minute, and one bigger next pilus to dentilis), movable digit edentate. The length of setae is smaller than that of Turkish individuals and closer to that of Amblyseius meridionalis sensu Livshitz & Kuznetsov (1972) (Döker et al. 2020).	en	CălugărK, Adina, StathakisK, Theodoros, Papadoulis, Georgios Th.

03D6BB11CE628560FE74F8A174A4FCD9.taxon	biology_ecology	Hosts / Substrates — The neotype was found on rotten palm leaves, but A. obtusus is mostly present on herbaceous – Achillea spp. and Senecio spp. (Asteraceae) (Papadoulis et al. 2009) and shrub plants. It was rarely observed on Vitis vinifera L. (Vitaceae) (Tixier et al. 2013). Previously, in Romania A. obtusus was reported from moss samples (bark and soil moss) taken from mature (over 80 years) natural forests located between 378 and 1445 m asl (Manu et al. 2018 a).	en	CălugărK, Adina, StathakisK, Theodoros, Papadoulis, Georgios Th.

03D6BB11CE628560FE74F8A174A4FCD9.taxon	discussion	Remarks — Amblyseius obtusus is a cosmopolitan species, reported in more than 30 countries (Demite et al. 2022). Also, its ubiquity character is showed by the fact that it was found in Greece at 2300 m asl (Papadoulis et al. 2009), in Romania in two parks of Bucharest (75 m asl) (Manu and Honciuc 2010), as well as at 378 – 1445 m asl (Manu et al. 2018 a) and with the occasion of our study at 11 m asl. However, in our study it was found in only meadow. Morphological characters and measurements of the Romanian specimens are very close to those described by Döker et al. (2020).	en	CălugărK, Adina, StathakisK, Theodoros, Papadoulis, Georgios Th. (2023): Predatory mites of the family Phytoseiidae (Acari: Mesostigmata) in Danube Delta Biosphere Reserve (Romania).

03D6BB11CE658560FE74FCF77205F999.taxon	discussion	Remarks — Our findings recommend this species as being a preferential praticolous one, in DDBR being found only in meadows, never in the samples from forests. Amblyseius terreus was described from Crimea and until now no other reports of this species are available. Therefore, this new record is also significant from zoogeographical point of view. With 70 specimens in total, in four stands, this species was one of the most abundant species within this survey. Morphological characters are very close to the original description.	en	CălugărK, Adina, StathakisK, Theodoros, Papadoulis, Georgios Th.

Morphological characters of the examined specimens generally fit with those of the original description.	en	CălugărK, Adina, StathakisK, Theodoros, Papadoulis, Georgios Th.

03D6BB11CE678562FE74FA94726FF8F5.taxon	discussion	Remarks — Proprioseiopsis messor is a cosmopolitan species reported in many countries and a common one, being found on many plants. However, only one specimen of P. messor was found in our study. The single collected specimen from Romania has morphological characters like the redescription provided by Ostovan et al. (2012). However, the dorsal setae z 4 and z 5 of the Romanian specimens are not serrate and have longer lengths than those from Iran, being comparable with populations of P. messor found in Ukraine (Ostovan et al. 2012).	en	CălugărK, Adina, StathakisK, Theodoros, Papadoulis, Georgios Th.
