Redescription of Isotominella geophila Delamare Deboutteville, 1948 from Algeria (Collembola, Entomobryomorpha, Isotomidae), a second world record for an Ivory Coast species

Isotominella geophila Delamare Deboutteville, 1948, from Massif Edough in Northeast Algeria, has been found for the second time and is redescribed. It is separated from all other genera of Isotomidae by the following combination of characters: absence of eyes and pigment, PAO oval, not subdivided, shorter than width of antennal base, dens partially crenulated, dental chaetotaxy with more than six setae (13+4), posterior central S-setae on thoracic tergite II to abdominal tergite IV in p-row, S-seta on abdominal tergite V not thickened and mucro bidentate. This species exhibits sexual dimorphism

A New species of Entomobrya from Northern Algeria (Collembola: Entomobryidae)

Two species of Entomobrya were found among 288 specimens of Collembola sampled in northern Algeria. The identification of the Entomobrya species requires some precautions and consideration of characters beyond color pattern. Preliminary identifications suggested the presence of E. mauretanica Handschin, 1925 (new status) and E. clitellaria Guthrie, 1903, but a detailed examination of the specimens assigned to E. clitellaria showed that a new species was involved which is described here. Entomobrya mauretanica has only been collected once before, was described inadequately, and is redescribed here

Global fine-resolution data on springtail abundance and community structure

Springtails (Collembola) inhabit soils from the Arctic to the Antarctic and comprise an estimated ~32% of all terrestrial arthropods on Earth. Here, we present a global, spatially-explicit database on springtail communities that includes 249,912 occurrences from 44,999 samples and 2,990 sites. These data are mainly raw sample-level records at the species level collected predominantly from private archives of the authors that were quality-controlled and taxonomically-standardised. Despite covering all continents, most of the sample-level data come from the European continent (82.5% of all samples) and represent four habitats: woodlands (57.4%), grasslands (14.0%), agrosystems (13.7%) and scrublands (9.0%). We included sampling by soil layers, and across seasons and years, representing temporal and spatial within-site variation in springtail communities. We also provided data use and sharing guidelines and R code to facilitate the use of the database by other researchers. This data paper describes a static version of the database at the publication date, but the database will be further expanded to include underrepresented regions and linked with trait data.</p

Edoughnura Deharveng, Kroua & Bedos, 2007, gen. nov.

Edoughnura gen. nov. Type species. Edoughnura rara sp. nov. Description. Small size. Light grey-blue pigment present on the body. Two pigmented ocelli on each side of the head. Ordinary dorsal chaetae bent, rather short, moderatly thick, not or hardly sheathed. S 7 not enlarged on Ant.IV. Tertiary granules present on the body. Reticulations inconspicuous or absent. Buccal cone short but not truncated. Labrum formula 2 / 2,4, the 2 + 2 distal chaetae subequal. Maxilla with two thin appressed lamellae, one distally bidentate and one unidentate. Mandible as a long, rather thin lamella ciliated in its distal part, with two very thin basal teeth, cilia-like. All dorsal tubercles developed. Eleven tubercles on head: (Af+CL), 2 Oc, 2 Di, 2 De, 2 DL and 2 (L+So). Tubercles Di fused on the axis from Abd.III to Abd.V. Chaetotaxy of the tubercle (Af + CL) on head with 4 or 5 supernumerary chaetae. Anus as a more or less transversal furrow. Tibiotarsal chaetotaxy 18,18, 17 (chaeta M absent). Claw untoothed. Etymology. The name of the genus refers to the region where it has been collected. Gender: feminine. Discussion. The genus Edoughnura differs from other Neanurini by a number of peculiar features: the morphology of dorsal chaetae, the external shift of chaeta F on the labium (as in Protanura papillata, Deharveng 1983: 17), the strongly modified mandible with long ciliated lamella, the presence of supernumerary chaetae on the central area of head (unique among Neanurini), the linear arrangement of Di chaetae on Th. II- III, the fusion of Di tubercles on Abd. III (as in Monobella cassagnaui Deharveng, 1981) and the anus as a more or less transversal furrow. With this combination of unusual characters, Edoughnura appears very isolated in the tribe Neanurini, with possible remote affinities with Endonura (fusion of tubercles Di on Abd. V combined with separation of tubercles Di and De on head). Its mandible recalls that of Crossodonthina, a genus from eastern Asia, which belongs to the tribe Lobellini and has no close relationships with Edoughnura. It suggests special feeding habits.Published as part of Deharveng, Louis, Kroua, Salah Hamra & Bedos, Anne, 2007, Edoughnura rara n. gen., n. sp., an enigmatic genus of Neanurinae Collembola from the Edough Massif (Algeria), pp. 57-61 in Zootaxa 1652 on page 58, DOI: 10.5281/zenodo.17978

Dorsal ordinary chaetae rather thin, bent, inconspicuously or weakly sheathed, pointed or finely blunt, smooth, sometimes bifurcate; some longer and thicker, laterally and on Abd.V-VI. On Abd.V, Di 2 and Di 3 three times shorter than Di 1. S-chaetae very thin, shorter than the closest macrochaetae. Slight plurichaetosis on head, no plurichaetosis on tergites. S-chaetae formula on half tergites from Th.I to Abd.V: 0, 2 +ms, 2 / 1, 1, 1, 1, 1. Head. S-chaetae of Ant.IV of medium length, thick, slightly bent, with S 1 and S 2 slightly shorter and thinner than others; apical vesicle trilobed. Buccal cone short but not truncated (Fig. 2). Cardo strongly bent in its externo-distal part. Maxilla with two thin appressed lamellae, one distally bidentate and one unidentate, mandible as a long, rather thin, ciliated lamella, with two very thin, cilia-like basal teeth (Fig. 3), turned back into the head. Labium with 4 basal (E,F,G,f), 3 distal (A,C,D) and 2-3 lateral (c,d, and sometimes e) chaetae, with chaetae A as long as C and macrochaeta F shift antero-externally (Fig. 2); x-papillae not seen. Labrum truncated-rounded, with ventral sclerifications narrow; its 2 + 2 distal chaetae long and subequal; 1 + 1 lateral prelabral chaetae present, the two inner ones apparently absent (Fig. 4). Eleven tubercles on head (Fig. 1). Af fused to CL with an area devoid of tertiary granules between C and F. Chaeta E absent. Supernumerary chaetae on the tubercle (Af+CL): two at the level of A, two at the level of O, one uneven at the level of C (sometimes absent), and several on the tubercle (L+So) (Fig. 1). Chaetae Di 1 about 1.5 times longer than Di 2, and De 1 about 2 times longer than De 2. Body and appendages chaetotaxy and tubercles (as in Fig. 1 and Tab. 1). Di tubercles fused on Abd.V, Abd.IV and on Abd.III, separated on Abd.II (not always clearly) and forward. Di 1, Di 2 and Di 3 subequal and arranged in an oblique line on Th.II–III. S-chaetae at level of De 2 on Th.II–III and at level of De 1 on Abd.I– III (Fig. 1). On Abd.V, Di 2 and Di 3 short, subequal, at same level, slightly posterior to the edge of the tubercle. Furcal rest as a weak integument swelling, with 6 chaetae and no distinct microchaetae. Anus as a more or less transversal furrow. Tibiotarsal chaetotaxy 18, 18, 17 (chaeta M absent). Claw untoothed. Etymology. The name of the species refers to its rarity compared to other Neanurinae of the Edough massif, and the uniqueness its morphological characteristics.Published as part of Deharveng, Louis, Kroua, Salah Hamra & Bedos, Anne, 2007, Edoughnura rara n. gen., n. sp., an enigmatic genus of Neanurinae Collembola from the Edough Massif (Algeria), pp. 57-61 in Zootaxa 1652 on pages 58-61, DOI: 10.5281/zenodo.17978
