Diagnosis.

( Condé 1993, 1996; Sendra et al. 2020 b): Elongated body. Epicuticle smooth under optical microscope. Antennae with 23-25 antennomeres; four simple olfactory chemoreceptors in cupuliform organ; slightly protruding frontal process with some slightly tubercular setae. Pronotum with 1 + 1 ma, 3 + 3 la, 2 + 2 lp macrosetae; mesonotum with 1 + 1 ma, 3 + 3 la, 2 + 2 lp macrosetae; metanotum with 1 + 1 ma, 1 + 1 (2 + 1) la, 2 + 2 lp macrosetae; long, thin, barbed notal macrosetae; short, smooth clothing setae. Two ventral tibial macrosetae; unequal claws (1.3) with large lateral crests, posterior claw with a backward overhang; pretarsal processes short, with a few sparse barbs. Urotergites I – II with 1 + 1 post macrosetae; urotergite III with 2 + 2 post macrosetae; urotergites IV – V with 1 + 1 la, 5 + 5 post macrosetae; urotergites VI – VII with 2 + 2 la, 5 + 5 post macrosetae; urotergite VIII with 6 + 6 post macrosetae; abdominal segment IX with 8 + 8 post macrosetae; urosternite I with 7 + 7, urosternites II – VII with 5 + 5, urosternite VIII with 2 + 2 macrosetae; first urosternite of male with a large field of up to 302 glandular g 1 setae on the posterior portion and supporting subcylindrical large appendages bearing a field of up to 43 glandular a 1 setae (Fig. 10 View Figure 10 ); first urosternite in female with subcylindrical female appendages bearing glandular a 1 setae.

Habitat and distribution.

Non-troglomorphic species. Until now, the species was known only from Peştera Movile in Southern Dobruja, Romania. Here, we report it for the first time from Bulgaria, based on specimens found in two caves on the Shumen Plateau and one in the Strandzha Mountains. Additionally, Sendra et al. (2020) reported seven specimens of Plusiocampa ( Plusiocampa) aff. isterina found in Ledenjača Cave, Bosnia and Herzegovina. These specimens were distinguished from the typical form by a higher number of antennomeres (25–28), the presence of six olfactory chemoreceptors in a relatively large cupuliform organ (occupying one-third of a short antennomere), and a more prominent frontal process bearing distinctive tuberculate setae.

It is interesting that two species of Diplura are recorded in the Zandana cave – P. arbanisiensis and P. isterina . Future research will show whether these are indeed different species or whether the material is misidentified (Fig. 21 View Figure 21 ).
