Antennoseius pannonicus Willmann, 1951: 109 .

Diagnosis Podonotal and opisthonotal shields with 19 and 15 pairs of setae, respectively; seta j1 simple, short; j2-j5 short, robust; other podonotal and opisthonotal setae needle-like, usually slightly thickened near the base, sometimes with short barbs. Sternal shield with two pairs of setae; with a prominent brownish crown-shaped sclerotized structure behind st1 level; setae st3 off sternal shield on soft cuticle. Anal shield pear-shaped. Peritremes reaching to anterior level of coxae I. Anterior margin of epistome with three short dentate projections. Deutosternal groove with seven multidentate rows. Coxal setae on legs I-IV simple.

Measurements of the Iranian specimen (in μm) – Idiosoma 706 long, 345 wide at the level of setae j6. Podonotal and opisthonotal shields 359 and 288 long and 291 and 294 wide at the widest level, respectively. Sternal shield 150 long and 107 wide at st2 level. Genital shield 167 long and 82 wide at the level of st5. Anal shield 127 long and 91 wide at broadest level (length of the shields were measured from anterior to poster margins along the mid-line).

Note – Size of the collected specimen in this research is considerably larger than that of the original description [idiosoma length 540, width 285] and also re-description of the species by Faraji et al. (2017) [idiosoma length 565 (530–590)]. However, all diagnostic features of the Iranian specimen conform to those presented in the original description and re-description of the species.

World distribution – This species has been found in association with different species of carabid beetles, including Amara consularis (Duftschmid) from Eastern Ukrain ( Trach 2013); Calathus fuscipes (Goeze) from France ( Faraji et al. 2017); Harpalus calceatus (Duftschmid) from Eastern Ukrain and France ( Trach 2013; Faraji et al. 2017); Harpalus distinguendus (Duftschmid) from France ( Faraji et al. 2017); Harpalus rufipes (De Geer) from France ( Faraji et al. 2017); Nebria salina Fairmair & Laboulbène from France ( Faraji et al. 2017); Ophonus diffinis (Dejean) from Eastern Ukrain ( Trach 2013); Poecilus cupreus (L.) from France ( Faraji et al. 2017); Pterostichus madidus (Fabricius) from France ( Faraji et al. 2017); Pterostichus melanarius (Illiger) from France ( Faraji et al. 2017); Scybalicus oblongiusculus (Dejean) from France ( Faraji et al. 2017) and Harpalus sp. in this paper. Also, the species has been collected in litter ( Evans 1958) and soil ( Willmann 1951; Ryke 1962; Kontschán et al. 2016).
