Sugaentulus masumii Imadate 1978
No full textSugaentulus masumii Imadaté, 1978 (Figs. 34–39) The holotype of Sugaentulus masumii Imadaté, 1978 (NSMT –Ap 62), allotype (NSMT –Ap 62) and two paratypes (NSMT –Ap 70), deposited in National Science Museum of Natural History, Tokyo, Japan, were studied recently by Dr. Nakamura Osami, who kindly provided new illustrations of Imadaté’s species for comparison with S. andrzeji. These drawings along with Imadaté’s original description form the basis for a partial redescription of S. masumii and differentiation of the two species. Maxillary gland characterized by wide calyx with slightly granulated surface and with distinct extra appendix (Fig. 34). Basal sensilla on maxillary palps slender, near setiform (Figs. 35 A, B). Sensillum on labial palp very broad (Fig. 35 C). Accessory setae on meso- and metanotum and tergites I–VI sensilliform, blunt, not pointed (Figs. 36, 37), on VII longer and setiform (Fig. 38). Striate band on abdominal segment VIII distinct with parallel and regularly oriented striae (Fig. 39). Striae shorter than the band width. On ventral side, some striae between anterior line of band and cuticular area only in holotype, not observed in allotype and two paratypes.Published as part of Shrubovych, Julia & Rusek, Josef, 2010, Sugaentulus andrzeji sp. nov. from Siberia, Russia (Protura: Acerentomidae: Acerentominae) and key to Acerentominae genera, pp. 59-68 in Zootaxa 2720 on page 66, DOI: 10.5281/zenodo.19987
Sugaentulus andrzeji
No full textDifferentiation of S. andrzeji and S. masumii Sugaentulus andrzeji and S. masumii both possess 2 + 2 A -setae on meso- and metanotum, the abdominal legs bear two nearly equal setae, and the labial palps possess an apical tuft of setae. They also have in common a well developed striate band, anterior seta P 3 on tergites II–VI, and the foretarsus with a claviform t 1 but lacking sensillum b’. The new species differs from Sugaentulus masumii in having a slender maxillary calyx without appendices (in S. masumii calyx broader with extra appendix), in leaf-like sensilla on maxillary palps (slender and nearly setiform in S. masumii), in finger-like sensillum on labial palps (broad and leaf-like in former species), setiform foretarsal seta δ 4 (sensilliform and short in former species), and setiform shape of foretarsal sensilla d and f (in S. masumii they are parallel to the rounded tip).Published as part of Shrubovych, Julia & Rusek, Josef, 2010, Sugaentulus andrzeji sp. nov. from Siberia, Russia (Protura: Acerentomidae: Acerentominae) and key to Acerentominae genera, pp. 59-68 in Zootaxa 2720 on page 67, DOI: 10.5281/zenodo.19987
Stenaphorura lubbocki Bagnall 1935
No full textStenaphorura lubbocki Bagnall, 1935 Figs 11–18 Material. Lectotype, first label: type, Dames Dyke, EYks, n/s viii. 34 R.S. Bagnall Coll. Brit. Mus. 1959 – 591, second label: Stenaphorura quadrispina Börner Det. J.T.Salmon Oct. 1960. This specimen was designated as a lectotype, as recommended by P. N. Lawrence in a letter to me of 11 th October, 1976: ”Although the slide (of lubbocki) is marked “ TYPE ”, it is evident, from the original description, that it is one of two syntypes.” Redescription. Body elongated (Figs 11, 12), 1330 μm long and 280 μm wide, white. Granulation of integument unequally large, coarse, with areas of very large secondary granules, especially on head and last abdominal tergite (3 μm in diameter) (Figs 17, 18). Secondary granules on nota and abdominal tergites 1.5– 2 μm in diameter. Macrosetae well differentiated from the microsetae (Figs 11,12). Chaetotaxy of dorsal side of body as in following formula: 1) m 2, m 4 and m 5 present, 2) p 2 missing, 3) p 2 present, 4) m 2 and m 4 present, 5) p 2 missing, 6) m 2, m 3 and m 4 present, 7) a 1 missing (transferred into m-row as m 1 chaeta), 8) m 1, m 2 and m 4 present, 9) p 2, p 3, p 5 and one unpaired p x present, 10) only m 4 present. Lengths of some setae: metanotum—a 1 12 μm, m 2 38 μm, m 4 50 μm, p 3 15 μm, p 5 26 μm, s’ 3 μm; abdominal tergite IV––a 2 17 μm, m 1 15 μm, m 2 60 μm, m 4 60 μm, p x 11 μm, p 2 13 μm; abdominal tergite V––a 1 16 μm, a 2 71 μm, m 4 80 p 2 23 μm, p 3 16 μm, p 5 16 μm. Pseudocelli of oval shape 6–8 x 9 μm in size, with crescent, narrow opening, the lid with fine primary granulation and three, sometimes indistinct rips (Fig. 15). Number and arrangement of pseudocelli: 11 / 111 / 11111 (Figs 11, 2). Antennae (135 μm) shorter than head (270 μm). Lengths of antennal segments I: II: III: IV as 30: 30: 35: 40 μm. On antennal segment IV (Fig. 13) five thickened sensilla a–e and two short, thin sensory rods (microsensillum and subapical organite) in indistinct pits. Sensillum d does not reach insertion of sensillum a, and sensillum e reach clearly insertion of sensillum c. Apical vesicle small, globular with a shallow depression on top (Figs 13, 14). Antennal organ III with two small, thin sensory rods concealed behind integument folds, and three thick sensory clubs. Integumantal fold subdivided into three papillae (Fig. 13), not covering sensory clubs. One thick and bent sensory club present on ventral side of antennal segment III (Figs 13, 14). Postantennal organ (Fig. 17) 40 μm long, 6.3 times longer than frontal pseudocellus, in shallow depression with 75 simple, slim and narrow vesicles lying in two parallel rows. Legs without clavate tibiotarsal hairs. Claw without teeth, 30 μm long, empodial appendage small, 3 μm long. Each segment of all pairs of legs with areas or rings of coarse granulation on smooth integument. Setae p 2, p 3 and p 5 on abdominal tergite V as sensilla, slim, not as thickened as in Mesaphorura spp. Abdominal tergite VI with two pairs of anal spines on distinct papillae (Fig. 18), without crescent ridges in front and without wart-like tubercles. Anal spines 30 μm (anterior ones) and 48 μm (posterior pair) long. Dorsal transversal row between both pairs of anal spines with three mesochaetae. Ventral tube with 6 + 6 setae (including the basal ones). No trace of furca. Only one female examined: genital plate with 2 microchaetae on frontal lid. Affinity. Stenaphorura lubbocki is related to S. japygiformis. The differences between them are given in the Discussion of S. japygiformis.Published as part of Rusek, Josef, 2010, The enigma of the genus Stenaphorura Absolon, 1900 (Collembola, Tullbergiinae), pp. 43-53 in Zootaxa 2338 on pages 49-52, DOI: 10.5281/zenodo.19325
