Damages produced by eriophyid mites to Olea europaea subsp. europaea cv. arauco have been known for many years. In a previous publication, the presence of Aceria oleae (Nalepa) and Oxycenus maxwelli, (Keifer) in Argentina was reported, but the species was not definitively identified. In the past five years, damage caused by this mite to leaves, flowers and fruits in many production areas was very high, leading to the need for further investigations about this mite, the most numerous mite species on this plant in Argentina. The present paper is divided in three parts: a) a morphological characterization of A. oleae based on specimens collected in Argentina, with the use of SEM; b) a study of its life cycle; and c) an illustration of its damage to leaves and fruits. The morphological study led to the confirmation of the identity of the species and to the determination of morphological aspects not previously mentioned in the literature. Life cycle and damage were observed to be similar to what has been previously mentioned in the literature for the same mite in other countries.

Xenotarsonemus spiniphorus Lofego, Moraes & Ochoa Xenotarsonemus spiniphorus Lofego, Moraes & Ochoa, 2007: 11. Specimens examined: Cananéia (SP): Gomidesia sp., VII-2012 (19 ♀, 1 ♂); Blefarocalix salicifolium, I-2013 (2 ♀). Previous reports: São Paulo —Natural ecosystems (Cerrado): Campomanesia pubescens and Myrcia venulosa (Lofego et al. 2007); Natural ecosystems (Atlantic Forest): Trichillia casaretti (Demite et al. 2013) and on plant not mentioned (Demite et al. 2012). Among the 14 species nominally determined in this study, seven of these (F. pulvirosus, M, megassolenidii, T. bilobatus, T. confusus, X. brachytegula, X. cerrado and X. spniphorus) were also found in the Cerrado biome (Lofego & Moraes, 2006; Demite et al. 2009; Rezende et al. 2014). This similarity between the tarsonemids fauna in these two biomes is an unexpected fact, since they are structurally quite different biomes; the Atlantic Forest is a tropical forest, and the Cerrado is a savanna (IBGE 2012). The remaining vegetation of the Atlantic Forest shelters a great diversity of tarsonemids, many still new to science. In the present study, the sampling was only a small portion of the entire diversity of the Atlantic Forest (eight sampling areas, with only five plant species from the same family were sampled at each area) and a considerable richness of tarsonemids species was found. In this study, of the identified species, six (40%) were unknown until recently to science (D. esalqi, K. ochoai, M. caissara, O. dux, X. quiriri, X. scorpius) (Lofego et al. 2015, 2016, 2018, 2019, Rezende et al. 2015b), in addition to the one described here (Tarsonemus conduru Lofego & Cavalcante sp. nov.). A great richness of tarsonemid was also recorded in the Atlantic Forest biome by Demite et al. (2012), in a more restricted area in the interior of the São Paulo state, but with a larger sampling, where 100 plant species from several botanical families were collected in 18 areas. In that study, Tarsonemidae was the second family with the highest richness (47 species). The data from the present study reveal the impressive richness of the family Tarsonemidae in the Atlantic Forest; and indicate how much further efforts are needed to better understand the diversity in this hotspot., Published as part of Demite, Peterson R., Cavalcante, Ana C.

Differential diagnosis: The new species resembles Tarsonemus stammeri Schaarschmidt in having median lobes on the posterior margin of the prodorsal shield and short setae on shields C, D, EF and H (less than 20 µm). However, that species differs from the new species here described by the elongate pharynx, sejugal apodeme well sclerotized throughout, prosternal apodema sclerotized only anteriad of apodeme 2, and dorsal seta d about 20 μm long. Remarks: Nothing is known about the biology or ecology of this new species. Larva and Male: Unknown Etymology: The specific designation refers to the type locality “Serra do Conduru” (Conduru ridge)., Published as part of Demite, Peterson R., Cavalcante, Ana C.

All specimens collected by C.A. Ortega-Ojeda. Supplementary description. Adult female (n = 12) (Figs 17���18). Gnathosoma. Measurements of the specimens collected for the cheliceral digits, corniculi, hypostomal and subcapitular setae are within the respective ranges mentioned in the original description. Dorsal idiosoma. Dorsal shield about 20% shorter and narrower than reported in the original description of the species. Setal measurements were always within the respective ranges mentioned in the original description. Ventral idiosoma. Measurements of tritosternum, ventral shields and setae compatible with measurements given in the original description, overlapping the corresponding ranges. Spermatheca. Phytoseiid-type, clearly distinguishable as a sclerotised, elongated cup-shaped structure projecting from the posterior external margin of the base of the coxa IV, ending in a membranous saccular structure. Legs. Lengths and setation very similar to what were reported in the original description. Leg IV with six macrosetae: three on genu [ad1 63 (60-65), ad2 41 (36-44) and pd1 55 (52-57)]; two on tibia [ad1 41 (34-44) and pd1 54 (52-57)] and on one on basitarsus [pd3 64 (62-65)]. Remarks. This is the first record of this species outside of Brazil. The specimens collected from Ecuador fit well the description provided by Castilho et al. (2012b), based on females from Brazil. Given the very satisfactory original description of this species, new illustrations are not presented in this paper, except for the spermatheca and leg IV macrosetae. The presence of macrosetae on leg IV is not shown in the original description, but an examination of the type specimens showed that they are similar to what is shown herein for the Ecuadorian specimens., Published as part of Melo-Molina, Elsa L., Santos, Jandir C., De Moraes, Gilberto J. & Castilho, Raphael C., 2021, Gamasiphis species (Acari: Mesostigmata: Ologamasidae) from Ecuador, with description of a new species and new records, pp. 410-418 in Zootaxa 5068 (3) on pages 416-417, DOI: 10.11646/zootaxa.5068.3.5, http://zenodo.org/record/5707004, {"references":["Castilho, R.

Spermatheca (Fig. 7). Phytoseiid-type. Spermathecal apparatus distinguishable as a membranous tubular structure, extending medially from base of coxa IV. Legs. Lengths: I: 352 (330–364); II: 277 (250–296); III: 242 (230–247); IV: 339 (320–351). Numbers of setae on segments of legs I–IV: coxa: 2, 2, 2, 1; trochanter: 6, 5, 5, 5; femur: 13, 11, 6, 6; genu: 13, 11, 9, 8; tibia: 14, 10, 8, 9; tarsus II–IV: 18, 18, 17.

All legs with pretarsi, with elongate ambulacral stalk and a pair of strongly sclerotised claws. Etymology. The species is named in honor of the daughter of the first author, Victoria Eugenia Martinez (Vikki). Remarks. Gamasiphis vikkiae Melo-Molina & Santos n. sp. is most similar to G. adanalis Karg, 1990, but the latter has 20 pairs of setae on the podonotal region (s1 absent and only three pairs of r setae); 12 pairs of setae on the opisthonotal region; the dorsal setae ranging between 15-20 long; setae j2, j3, j4, j5, z3 and Z1 at most 0.6 times as long as distance to the base of the respective subsequent setae. In the key to Gamasiphis species provided by Castilho et al. (2012b), couplet 52 (page 1993) would require the following adjustment for inclusion of this new species: 52.
