Pronotum light brown with black pile, longer than on head, posterior margin of internal area with two punctiform marks united or separated; suprahumeral lobes reduced. Mesonotum chestnut brown covered with black bristles; median black marks comma shaped; lateral marks only blackened at the base; scutal depression black. Cruciform elevation wide, flattened, with posterior apices not prominent and separate from one another to level of mesoscutellar expansions (fig. 1 B). Male operculum brown, covered with golden bristles; short, posterior-lateral angle slightly obtuse, posterior margin sinuate (fig. 2 A). Meracanthus vestigial.

Male sternite VIII with concavity on posterior margin. Genitalia as in figs. 2 B and C. Wings. Fore wing hyaline with basal cell, proximal clavus and basal membrane blackened (fig. 1 E). Hind wing wide and as long as half of the fore wing; blackened at base (fig. 1 F). Male measurements (in mm). N = 15 males, average (range). Body length: 26.9 (26.1–27.8); fore wing length: 35.2 (34.2–37.4); fore wing width: 10.7 (10.0– 11.5); hind wing length: 18.2 (17.4–19.4); hind wing width: 8.1 (7.2–8.7); head width: 12.1 (11.6–12.5); mesonotum width: 9.9 (9.4–10.6); ocellus–ocellus distance: 1.6 (1.5–1.7); ocellus-eye distance: 3.5 (3.45–3.65). Female measurements (in mm). N = 15 females, average (range). Body length: 27.7 (25.5 –32.0); fore wing length: 38.4 (35.1–42.1); fore wing width: 11.0 (10.1–12.2); hind wing length: 19.3 (16.8–22.1); hind wing width: 8.6 (8.8–9.1); head width: 12.8 (11.0–14.0); mesonotum width: 10.0 (9.0–11.0); ocellus-ocellus distance: 1.6 (1.4–1.8); ocellus-eye distance: 3.5 (3.1 –4.0). Note. Analysis of the distribution of the nymphs and exuviae of F. sarutaiensis in coffee crops was presented by Ribeiro et al. (2006). Diagnosis. The genitalia of F. sarutaiensis are unique among known species of Fidicinoides. Fidicinoides sarutaiensis sp. n. can be differentiated from F. rosabasalae Santos & Martinelli, F. brunnea Boulard & Martinelli, F. besti Boulard & Martinelli, F. sucinalae Boulard & Martinelli, F. saccifera Boulard & Martinelli, F. jauffreti Boulard & Martinelli, F. dolosa Santos & Martinelli, F. pseudethelae Boulard & Martinelli, F. duckensis Boulard & Martinelli, and F. poulaini Boulard & Martin elli by the lack of infuscation of the transverse nerves of the apical fore wing cells as found in all of these species. The nonsmoky apical fore wings of F. sarutaiensis sp. n. differentiate it from F. opalina (Germar) and F. sericans (Stål). Fidicinoides pauliensis Boulard & Martinelli, F. picea (Wallker), F. pronoe (Walker), F. roberti (Distant), F. lacteipennis (Distant), F. determinata (Walker) and F. steindachneri (Kuhlgatz & Melichar) all have lateral mesonotal markings exceeding half the length of the mesonotum which are lacking in F. sarutaiensis sp. n. The mesonotal markings differentiate F. sarutaiensis sp. n. from F. spinicosta (Walker) and F. passerculus (Walker). The medial mesonotal marking of F. carmenae Santos & Martinelli and F. brisa (Walker) are roughly triangular rather than comma shaped as in F. sarutaiensis sp. n. Finally, the mesonotal marking of F. sarutaiensis sp. n. extends onto the submedian sigilla but is restricted to the parasidal suture in F. distanti (Goding) and whose abdomen possesses two arching transverse black marks.Published as part of Santos, Rodrigo Souza, Martinelli, Nilza Maria, Maccagnan, Douglas Henrique Bottura, Sanborn, Allen F. & Ribeiro, Renato, 2010, Description of new cicada species associated with the coffee plant and an identification key for the species of Fidicinoides (Hemiptera: Cicadidae) from Brazil, pp. 48-56 in Zootaxa 2602 on pages 50-52, DOI: 10.11646/zootaxa.2602.1.2, http://zenodo.org/record/19762

Suppression of ferromagnetic order by Ag-doping: a neutron scattering investigation on Ce<sub>2</sub>(Pd<sub>1−<i>x</i> </sub>Ag<sub> <i>x</i> </sub>)<sub>2</sub>In (<i>x</i> = 0.20, 0.50)
No full textThe ground state magnetic behaviour of Ce2(Pd0.8Ag0.2)2In and Ce2(Pd0.5Ag0.5)2In, found in the ferromagnetic branch of Ce2Pd2In, has been investigated by neutron powder diffraction at low temperature. Ce2(Pd0.8Ag0.2)2In is characterized by a ferromagnetic structure with the Ce moments aligned along the c-axis and values of 0.96(2) μB. The compound retains the P4/mbm throughout the magnetic transition, although the magnetic ordering is accompanied by a significant decrease of the lattice strain along [0 0 l], suggesting a magnetostructural contribution. The magnetic behaviour of Ce2(Pd0.5Ag0.5)2In is very different; this compound exhibits an extremely reduced magnetic scattering contribution in the diffraction pattern, that can be ascribed to a different kind of ferromagnetic ordering, with extremely reduced magnetic moments (∼0.1 μB) aligned along [0 l 0]. These results point to a competition between different types of magnetic correlations induced by Ag-substitution, giving rise to a magnetically frustrated scenario in Ce2(Pd0.5Ag0.5)2In.Fil: Martinelli, A..
