However, E. antoniae sp. nov. differs from these in the chaetotaxy of Abd IV and head, as well as in legs and antennal characters.</p><p>Considering only the “ true ” Mc, a single species, E. barbata Siqueira &amp; Bellini, 2020 (in Santos et al. 2020), shares the same Th II and Abd II – III chaetotaxy (0-1 / 0 - 1 / 0 - 0 - 1) but differs in head and Abd IV chaetotaxy and in empodium shape.

Slight humidity and localized fungal growth created favourable conditions, providing both moisture and nutritional resources (fungal hyphae, bacteria, and decaying plant material).</p><p>Willowsia solanella sp. nov. appears to be a synanthropic species inhabiting indoor environments where moisture, organic particles, and fungal growth are present. Like other members of the genus Willowsia, it is fungivorous – detritivorous, feeding primarily on superficial molds and fine organic debris. Its presence is not associated with damage to stored products and should be considered ecologically harmless, likely contributing to the decomposition of organic matter in human-modified microhabitats.</p><p>Remarks.</p><p>The genus Willowsia Shoebotham, 1917 ( Collembola, Entomobryidae) is characterized by the presence of scales and resembles Entomobrya in most other morphological traits. Species of Willowsia are widely distributed and occupy diverse habitats, including forest litter, bark surfaces, and anthropogenic environments. Several species are strongly synanthropic, frequently occurring in buildings, warehouses, and storage facilities where humidity and organic debris are present (Cipola and Katz 2021).</p><p>In Europe, including Romania, the genus is represented by relatively few species, with only three currently known: W. buski (Lubbock, 1870), W. nigromaculata (Lubbock, 1873), and W. platani (Nicolet, 1842) . Despite their wide distribution, taxonomy within the genus remains challenging due to pigmentation variability, incomplete historical descriptions, and limited modern chaetotaxic studies. Recent revisions have clarified species boundaries within the group, however, several undescribed taxa — particularly those from synanthropic environments — remain to be documented.</p><p>Among known species, W. samarkandica Martynova, 1972, W. yiningensis Zhang, Chen &amp; Deharveng, 2011, and W. zhaotongensis Chai &amp; Ma, 2017 share the same chaetotaxy in Abd II – III (2-3 / 0 - 2 - 1). However, these species differ in Th II chaetotaxy: four medial Mc and three lateral Mc in W. samarkandica, two medial and three lateral in W. yiningensis, and three medial and five lateral in W. zhaotongensis . Additionally, the number of central abdominal chaetae between trichobothria T 2 – T 4 on Abd IV differs: 32 in W. samarkandica, 22 in W. zhaotongensis, 14 in W. yiningensis, and 16 in W. solanella sp. nov. Differences between these species and the new taxon are summarized in Table 3.</p></div>	https://treatment.plazi.org/id/8514C9F3706553B4AB85FC8527576B70	Public Domain	No known copyright restrictions apply.
