Etymology. The name grandiporus is a compound of Latin grandis "large" and porus "pores", referring to the hypertrophied pre-anal pores in this species. Comments. This species belongs to the nicola subgroup of the obtusus species group (Chant & McMurtry, 2004) and is similar to Amblyseius franzellus Athias-Henriot, A. aricae Karg and A. intermedius González & Schuster, all of them described from Chile and Argentina. The new species is easily distinguished by the hypertrophied pre-anal pores. In addition, A. franzellus has six–seven denticles on cheliceral fixed digit and six pairs of dorsal solenostomes; A. aricae has longer dorsal setae, especially s 4 (90 v. 48), Z 4 and Z 5 (110, 180 v. 60, 110) and noticeable longer macrosetae on leg IV; A. intermedius differs by having longer s 4, Z 4 and Z 5 (72, 90, 160, respectively), eight teeth on fixed digit of chelicera and the male has five instead of four pre-anal setae.Published as part of Ferragut, Francisco & Navia, Denise, 2015, Phytoseiid mites (Acari: Phytoseiidae) from Patagonia and Tierra del Fuego, pp. 525-550 in Zootaxa 3990 (4) on pages 538-540, DOI: 10.11646/zootaxa.3990.4.3, http://zenodo.org/record/24068

Near Ushuaia (Argentina); 54 º 50 ' 51 " S, 68 º 29 ' 19 " W; 18 m asl. 10 January 2013. Holotype and some paratypes were deposited at Museo Nacional de Ciencias Naturales, Madrid, Spain (MNCN). Reference number of holotype: MNCN 20.02 / 17377; 1 paratype female MNCN 20.02 / 17378. Etymology. The specific name australis means "southern" or "austral" and refers to the occurrence of the species in the southernmost part of the Earth with arboreal vegetation. Comments. Chileseius belongs to the tribe Neoseiulini and is the unique genus in the family Phytoseiidae containing three species with three different idiosomal setal patterns: Ch. camposi 11 B: 11 A/JV– 3:ZV with 36 pairs of setae, Ch. australis sp. nov. 11 B: 10 C/JV 3:ZV, with 35 pairs of setae and Ch. paracamposi 11 B: 9 B/JV 3:ZV, with 34 pairs of setae. Table 1 summarizes the main morphological features to distinguish species within the genus Chileseius. The new species appears to be most closely related to Ch. camposi on the basis of sharing the presence of J 4, a similar spermathecal apparatus, ratio Z 4 / Z 5 and wide distance between pores gv 3.Published as part of Ferragut, Francisco & Navia, Denise, 2015, Phytoseiid mites (Acari: Phytoseiidae) from Patagonia and Tierra del Fuego, pp. 525-550 in Zootaxa 3990 (4) on pages 527-530, DOI: 10.11646/zootaxa.3990.4.3, http://zenodo.org/record/24068

Reference number of holotype: MNCN 20.02 / 17385; 1 female paratype MNCN 20.02 / 17386; 1 male paratype MNCN 20.02 / 17387. Etymology. The species name valdivianus derives from the evergreen Valdivian rain forests in which the mites were collected. Comments. This species belongs to the ariri species group (Chant & McMurtry, 2005) in which a few taxa have ventrianal shield vase-shaped, seven setae on genu II and three macrosetae on leg IV. Typhlodromips hamiltoni Chant & Yoshida-Shaul differs by having a cup-shaped spermatheca, macroseta on tibia IV shorter than macrosetae on genu and tarsus IV and only five pairs of dorsal solenostomes. Furthermore, setae Z 4 and Z 5 are, respectively, 60 and 113 long in T. hamiltoni and 44 and 65 in T. valdivianus. Typhlodromips robusticalyx Moraes, Zannou & Oliveira and T. sinensis Denmark & Muma have funnel-shaped calyx and ten denticles on fixed digit in the chelicera, instead of saccular calyx and seven teeth. Typhlodromips fordycei (De Leon) and T. compressus (Wu & Li) also resemble the new species. Both species have dorsal shield striated to reticulated instead of smooth and two and one macrosetae on leg IV, respectively, instead of three longer macrosetae in T. valdivianus.Published as part of Ferragut, Francisco & Navia, Denise, 2015, Phytoseiid mites (Acari: Phytoseiidae) from Patagonia and Tierra del Fuego, pp. 525-550 in Zootaxa 3990 (4) on pages 533-535, DOI: 10.11646/zootaxa.3990.4.3, http://zenodo.org/record/24068

Puerto Blest, Bariloche (Argentina), near the Argentina-Chile border; 41 º 01' 10 " S, 71 º 09' 35 " W; 837 m asl. 3 January 2013. Holotype and some paratypes were deposited at Museo Nacional de Ciencias Naturales, Madrid, Spain (MNCN). Reference number of holotype: MNCN 20.02 / 17379; 3 female paratypes (MNCN 20.02 / 17380, MNCN 20.02 / 17381, MNCN 20.02 / 17382); 2 male paratypes (MNCN 20.02 / 17383, MNCN 20.02 / 17384). Etymology. The term mapuche refers to the original inhabitants of the territories in south-central Chile and southwestern Argentina, the most numerous group of Indians in South America. Comments. This species belongs to the cucumeris subgroup in the cucumeris species group according to Chant & McMurtry (2003). Only four species in the subgroup have calyx bell or cup-shaped, seven setae on genu II and seven pairs of dorsal solenostomes. Neoseiulus mapuche can be differentiated from N. arenarius Denmark & Edland and N. communis Denmark & Edland by having the dorsal shield mostly smooth, five to seven teeth in the cheliceral fixed digit and only one macroseta on tarsus IV. It differs from N. koyamanus Ehara & Yokogawa by having only one tooth on movable digit of chelicera. Finally, N. umbraticus (Chant) has three macrosetae on leg IV, peritreme to j 3 and the male six pairs of pre-anal setae. The wide ventrianal shield and short dorsal setae closely resembles this species with N. camarus (El-Badry), N. ellesmerei (Chant & Hansell), N. inabanus (Ehara) and N. paraibensis (Moraes & McMurtry). Neoseiulus camarus and N. ellesmerei differ from the new species by having a bell-shaped calyx with a distinct neck between calyx and atrium. Neoseiulus inabanus and N. paraibensis have the dorsal shield evenly or partially reticulated instead of mostly smooth and they have, respectively, two and three medium to long macrosetae on leg IV, instead of one short macroseta. In addition, the calyx in the spermatheca is different, being short cup or bell-shaped in N. paraibensis and N. inabanus, respectively, and saccular in N. mapuche.Published as part of Ferragut, Francisco & Navia, Denise, 2015, Phytoseiid mites (Acari: Phytoseiidae) from Patagonia and Tierra del Fuego, pp. 525-550 in Zootaxa 3990 (4) on pages 530-533, DOI: 10.11646/zootaxa.3990.4.3, http://zenodo.org/record/24068
Solution of linear systems from an optimal control problem arising in wind simulation
No full textSeveral solution strategies for a class of large, sparse linear systems with a block 2 × 2 structure arising from the finite element discretization of an optimal control problem in wind simulation are introduced and analyzed. Block preconditioners and a sparse direct solver on the original coupled system are compared with a preconditioned GMRES iteration applied to a reduced system (Schur complement). Theoretical and experimental results demonstrate the effectiveness of the reduced system approach. Copyright © 2009 John Wiley & Sons, Ltd

Reference number of holotype and one paratype male: MNCN 20.02/ 17149; two paratype males: MNCN 20.02/ 17150. Etymology. The name adventitius (Latin) refers to the fact that this new species has one additional seta (S 2) in relation to the usual complement presented by other species of Typhloseiopsis. Remarks. This species resembles Typhloseiopsis pritchardi (Chant & Baker, 1965) and Typhloseiopsis neopritchardi Moraes & Mesa, 1988 in having separate ventral and anal shields. It can be distinguished from these and other species in the genus by having seta S 2. It further differs from T. pritchardi and T. neopritchardi by the longer s 4 and Z 4, and by the shape of the calyx of the spermatheca (short-saccular in the former and funnel shaped in the latter). The following key is provided to help in the separation of species of this genus.Published as part of Ferragut, Francisco, Moraes, Gilberto Jose & Navia, Denise, 2011, Phytoseiid mites (Acari: Phytoseiidae) of the Dominican Republic, with a re-definition of the genus Typhloseiopsis De Leon, pp. 37-53 in Zootaxa 2997 on pages 48-50, DOI: 10.5281/zenodo.20169
