During a study of some collembolan material collected in the last six years from Romania, two new species of
Samples of leaf litter and soil were collected between 2013 and 2017 and extracted with Berlese funnels. The specimens were cleared in lactic acid and KOH and subsequently mounted on slides using Marc Andre II or Swan’s medium.
Collections are referred to the following acronyms:
The taxonomic analysis was conducted using an Axio Scope A1 Zeiss microscope. Series of photographs were taken at different focal planes using an AxioCam ERC 5s camera mounted on microscope and processed with Adobe Photoshop CS3. Slide-mounted springtails were drawn using a Leica DM2500 compound microscope equipped with a camera lucida as well as phase-contrast and differential interference contrast (

This species is found in litter samples in mixed fir and beech forest.
The name of the new species is inspired by the name of the ski slope: Kalinderu, Bușteni town, Prahova county, Romania.

As we mentioned in the Introduction, 46 species and the two species newly described here belong to the genus
Six species are insufficiently described:
We express our gratitude to Lazăr Dumitru, the driver from
H. sibirica ‒ there is a discrepancy in the number of macrosetae on Abd. V given for this species. Pomorski (2001) has given 1+1 macroseta, while Weiner and Fjellberg (1994) in their redescription of H. sibirica have given 6 macrosetae on Abd. V.
H. polonica ‒ in the description Pomorski (1990) mentioned 1+1 poorly developed macroseta on Abd. V, while specimens from the type locality and other places have 3+3 macrosetae.
