On certain weaker forms of the Scheepers property
No full textWe introduce the weaker forms of the Scheepers property, namely almost
Scheepers (), weakly Scheepers in the sense of Sakai () and
weakly Scheepers in the sense of Ko\v{c}inac (). We explore many
topological properties of the weaker forms of the Scheepers property and
present few illustrative examples to make distinction between these spaces.
Certain situations are considered when all the weaker forms are equivalent. We
also make investigations on the weak variations as considered in this paper
concerning cardinalities. In particular we observe that
1. If every finite power of a space is (respectively, ), then is (respectively, ).
2. Every almost Lindel\"{o}f space of cardinality less than is
.
3. Let be Lindel\"{o}f and . If is a union of
many (respectively, , ) spaces, then
is (respectively, , ).
4. The Alexandroff duplicate of a space has the Scheepers
property if and only if has the property.
5. If is (respectively, ), then is also
(respectively, ).
Besides, few observations on productively , productively
and productively spaces are presented. Some open problems are also
given.Comment: arXiv admin note: text overlap with arXiv:2207.0859

Setanodosa jacquesi sp. nov. is only know from a single location in the Cape region. It has been collected floating on water in a rock pool. Etymology. We dedicate this species to its collector, Jacques Scheepers. Barcoding results. The mitochondrial genome of Brachystomella parvula has been recently published by Jiang et al. (2019). We give here the first COI sequences published for different genera, species and populations of the family, including two Setanodosa and two Brachystomella Agren, 1903 species (Fig. 8). Between-species divergences are high, ranging from 22 to 26 %, i.e. similar to or even higher than between-species divergences observed in other families according to available literature (Porco et al. 2012, Sun et al. 2018). Divergences within species are low (0-1.8 %). As expected, S. jacquesi sp. nov. is well separated from the sub-Antarctic species S. steineni, the only other species of the genus which has been barcoded so far.Published as part of Janion-Scheepers, Charlene & Deharveng, Louis, 2022, A shocking-red new species of Setanodosa Salmon, 1942 (Collembola: Brachystomellidae) from South Africa, pp. 483-495 in Zootaxa 5154 (4) on pages 484-488, DOI: 10.11646/zootaxa.5154.4.6, http://zenodo.org/record/665128

Aug. 2010, 33.981402°S, 20.826202°E, C. Janion-Scheepers. Holotype and 3 paratypes in SAMC, 3 paratypes in MNHN; 4 paratypes in MSPU.</p> <p> <b>Description.</b> Body length up to 1.0 mm. Grey, eye spot black (Fig. 5). Ant.I with 4 s-chaetae ventro-laterally of which 2 long chaeta-like and 2 short (set together in distal part or separately, Fig. 6), 3 basal microchaetae, 2 dorsal and 1 ventral. Inner s-chaetae of AO III small. Based on cornea, two ocelli on each side of head, set apart, a large anterior one and a smaller, often hardly visible, posterior one (Fig. 4). Eye spot undivided, the pigmentation often concealing the real number of ocelli in dark specimens (Fig. 5). PAO wide, ca 1.4 as long as internal crest of Claw III. Labral formula 4/554, apical folds sharp. Maxillary outer lobe with 4 sublobal hairs and trifurcate apical palp. Labial palp with 5 papillae (A–E) and incomplete set of guards (15, e7 absent), lateral process normal. Labium with 4 basomedian, 5 basolateral, and 4 proximal chaetae. Number of postlabial chaetae 3+3. Inner mouthparts as usual for the genus, maxillary head unmodified: both lamellae 1 and 6 with two rows of filaments (Fig. 10). Lower subcoxa of leg I with one outer chaeta. Tibiotarsi of all legs with only 7 chaetae in apical whorl. Claw without clear internal teeth, with two minute lateral teeth. Empodial appendage with broad lamella. Ventral tube with 2+2 latero-distal, 3+3 anterior, and 4 posterior chaetae (Fig. 3). Retinaculum with 4+4 teeth and 3 chaetae. Furcal subcoxa with 24–31 chaetae. Manubrial thickening simple. Anterior side of manubrium with numerous chaetae of which 2+2 shorter medial ones in its apical part, as common for the genus. Dens with numerous chaetae on anterior side and 7 chaetae on posterior side (2 basal, 2 median and 3 lateral) (Figs 8, 9). Mucro with 3 teeth.</p> <p>Ordinary chaetae slightly thickened, as usual for the genus. Axial chaetotaxy for Th.II, III, Abd.I, II with 12– 13+12–13, 10+10, 4–5+4–5, 3–4+3–4 chaetae, respectively. Macrochaetae differentiated, ciliate, on last abdominal segments with about 10 cilia (Fig. 7), on Abd.V 1.2–1.4 times longer than length of tergite. On Th.II–Abd.V, s-chaetae thin, well different from common chaetae, sensillary chaetotaxy (Figs 1, 2) as: 2al+4accp, 1al+4accp / 4 accp, 4 accp, 4 accp, 1 am+4 accp, 2 am+5 accp. From Th.II to Abd.III, s-chaetae accp4 and accp5 missing on each side of segment, and 2 s-chaetae (accp4 and accp6) missing on Abd.IV. On Th.II–Abd.III, ms-chaetae as 1,1/1,0,1. On Abd.III, ms-chaetae large, as long as s-chaeta (Fig. 1). Number of common chaetae in p-row between s-chaetae and ms-chaetae: 2s1s1s3s (Abd.I), 2– 2.5s 1s1s3s (Abd.II), 2–3s1s1s2ms1s (Abd.III), 1– 0.5s 1s1s2(s) (Abd.IV) (Figs 1, 2). Males not seen.</p> <p> <b>Distribution.</b> The new species is currently known only from the type locality, which is in the faunistically specific inner area of Western Cape.</p> <p> <b>Remarks.</b> The strongly reduced s-chaetae chaetotaxy is shared with only <i>P. sexsetosa</i> Potapov, Janion & Deharveng, 2011 from which the new species differs by 7 (vs 6) posterior chaetae on dens and s6 on Abd.IV and e 7 in labial palp missing. The absence of s6 on Abd.IV was previously unknown in the genus. Chaetae of posterior side of dens (“2 median + 3 lateral”) are as in Holarctic species. The “2 + 3” chaetae on the dens and the absence of lateral s6-chaetae on Abd.IV sharply define this new species in South Africa. Formally, <i>P. ruseki</i> <b>sp. nov</b>. can be compared with <i>P. trichaetosa</i> (Martynova in Martynova <i>et al</i>. 1977) (Palaearctic) which has nearly the same number of s-chaetae on body. <i>Parisotoma trichaetosa</i> differs by four teeth on the mucro, the presence of ms on Abd.II and other essential characters.</p> <p> <b>Name derivation.</b> The species is dedicated to our Czech colleague Josef Rusek (1938–2022), who contributed immensely to the taxonomy of the genus <i>Parisotoma</i>.</p>Published as part of <i>Janion-Scheepers, Charlene, Potapov, Mikhail & Deharveng, Louis, 2023, New and little-known Isotominae (Collembola, Isotomidae) from South Africa, pp. 337-347 in Zootaxa 5346 (3)</i> on pages 338-339, DOI: 10.11646/zootaxa.5346.3.8, <a href="http://zenodo.org/record/8390313">http://zenodo.org/record/8390313</a>
