Zootaxa 5717 (3): 403-418, DOI: 10.11646/zootaxa.5717.3.6, URL: https://doi.org/10.11646/zootaxa.5717.3.6
FB3FE532FFF1FFC5668DFE83FED7FC3F.taxon	discussion	Discussion. There are two different published nomenclatures that code for postlabial chaetae in Entomobryidae, Chen & Christiansen (1993) and Soto-Adames (2010). According to Soto-Adames (2010), the short ciliated chaetae X and X’ that we have observed in L. divisus sp nov. correspond to O 1 and L 2 respectively, while in the scheme of Chen & Christiansen (1993,) the O 1 chaeta is X, and the L 2 chaeta has no equivalent and is named X’ in the present paper (Fig. 8). * pse always divided; + pse divided or not divided depending on the specimens; (#) group of pse in central position of the tergum. The new species belongs to the L. curvicollis - group by the following characters (Mateos & Petersen 2012): presence of scales on the antennae, legs and dorsal side of manubrium; mesothorax protruded over the head; labial chaeta M 1 shorter than M 2; presence of chaeta s on abd. IV; dorsal macrochaetae formula A 0 A 2 Pa 5 / 00 / 0101 + 3. The best diagnostic character of the Lepidocyrtus divisus sp. nov. is the presence of divided pseudopores in the dorsomedial position of some tergites. This character differentiates the new species from all other species of the L. curvicollis - group. Another three important diagnostic characters of the new species are: 1 — Presence of smooth chaetae at the base of the labium. Within the L. curvicollis - group the only species described so far with smooth labial chaetae is L. curvicollis, and it is differentiated from the new species by presenting many dorsal pseudopores in abd. IV and not presenting lateral or ventral pseudopores in this segment. 2 — Presence of pseudopores on abd. IV located externally to the lateral suture. Within the L. curvicollis - group, L. mariani Traser & Danyi, 2008 is the only species described so far with lateral pseudopores in abd. IV and it is differentiated from the new species by also having lateral pseudopores from th. III to abd. III, and for having all chaeta at base of labium ciliated (although not typical, occasionally also L. mariani can have smooth labial chaetae m 1, r, l 1 and l 2, see Winkler & Mateos 2018). 3 — Presence of ventral pseudopores in abd. IV located at the base of the inner edge of BP 4. The presence of ventral pseudopores in abd. IV is observed in four species of the L. curvicollis - group, but in different positions depending on the species. In L. flexicollis these pseudopores are distributed forming a line along the inner edge of BP 4 (see Mateos et al. 2021 Fig. S 3), while in the species L. divisus sp. nov, L. mariani and L. montseniensis these pseudopores are located grouped at the base of the inner edge of BP 4 (Fig. 21 B). Other characters that differentiate the new species from the rest of the species of the L. curvicollis - group are indicated in Table 2.	en	Mateos, Eduardo, Zhang, Bing (2025): New species of the European Lepidocyrtus curvicollis-group (Collembola: Entomobryidae).
