(Received 5 January 2014; accepted 6 March 2014; published online 10 April 2014) Four new species of eriophyoid mites associated with native palm trees (Arecaceae) from the Amazon and Pantanal, Brazil, and from Cocora Andean Valley, Colombia, are described and illustrated. They include three new species in the Eriophyidae, all in Notostrix Keifer – Notostrix speciosa sp. nov., from Attalea speciosa Mart. ex. Spreng; Notostrix juma sp. nov., from Bactris glaucescens Drude; and Notostrix colombiana sp. nov., from Ceroxylon quindiuense H. Karst; and one new species in the Phytoptidae, Propilus flechtmanni sp. nov., from Astrocaryum murumuru Mart. ex. Spreng. Morphological differences between Notostrix and Propilus species, including the new taxa herein described, are summarized. http://zoobank.org/urn:lsid:zoobank.org:pub:802465BF-BA15-4915-83CA-C8847A878723 Keywords: Eriophyidae; Phytoptidae; taxonomy; Neotropical; Brazil; Colombia

Introduction Palm trees in the Arecaceae family represent a plant group of great socio-economic importance for their products and also one of those most used as ornamentals in tropical and subtropical areas (Henderson et al. 1995; Lorenzi et al. 1996). Sixty-seven eriophyoid species from 33 genera, associated with 54 palm tree species from 26 genera, have been described (Navia et al. 2007; Reis et al. 2012; Flechtmann and Moraes 2013). However considering the high diversity of this group of plants, just a small fraction has been studied related to its acarofauna, and numerous palms from some biomes have not yet been surveyed, especially endemic palm trees in Neotropical areas. Eriophyoid mites have been reported as pests on cultivated palm trees, e.g. coconut, oil palm and queen palm, or causing no apparent damage on native or introduced ornamental palms. Some Eriophyoidea genera are known to occur exclusively on palm trees; for example, Notostrix Keifer and Amrineus Flechtmann in the Eriophyidae and Acathrix Keifer, Propilus Keifer and Mackiella Keifer in the Phytoptidae show a strict and interesting relationship that deserves further study. In this paper, we described four new species from Eriophyoidea mites associated with palm trees in different South American biomes – Amazon rainforest and Pantanal wetlands in Brazil, and Cocora Andean Valley in Colombia. In the Amazon rainforest, Rondonia State, Attalea speciosa Mart. ex. Spreng and Astrocaryum murumuru Mart. were surveyed. In the Pantanal wetlands, Mato Grosso State, eriophyoid mites were collected from A. speciosa and Bactris glaucescens Drude.

mites associated with the endemic “Quindío wax palm”, Ceroxylon quindiuense (Karst.) H. Wendl, the national tree of Colombia that is also the world´s tallest palm and monocot (Madriñan and Schultes 1995), were collected. The new taxa include three new Eriophyidae species in the Phyllocoptinae, Notostrix genus, namely Notostrix speciosa sp. nov. from A. speciosa, Notostrix juma sp. nov. from B. glaucescens and Notostrix colombiana sp. nov. from C. quindiuense. Currently 14 Notostrix species are known (Keifer 1963; Mohanasundaram 1982; Flechtmann 1998; Gondim et al. 2000; Navia and Flechtmann 2003, 2005; Flechtmann and Moraes 2013). The fourth taxon belongs to the genus Propilus in the Phytoptidae, Sierraphytoptinae, Mackiellini, namely Propilus flechtmanni sp. nov., collected from A. murumuru. This new species represents the eighth species to be described in the genus. Morphological differences between Notostrix species and also between Propilus species, including the new species herein described, are summarized. Remarks on morphological traits of Notostrix nasutiformes Gondim, Flechtmann & Moraes, 2000 specimens collected from Pantanal are included. Materials and methods Mites were collected from leaf samples by direct examination under a dissecting stereomicroscope and mounted in modified Berlese medium (Amrine and Manson 1996). Slide-mounted specimens were studied using a research phase and differential interference contrast microscope (Eclipse 80i Nikon, Tokyo).


International Journal of Acarology Terminology follows that of Lindquist (1996) and classification is based on Amrine et al. (2003). Measurements are given in micrometres (µm) and, unless stated otherwise, refer to the length of the structure. In the description of the female, each measurement of the holotype precedes the corresponding range for the paratypes. Some measurements of the holotype or paratypes could not be taken because of the position in which the specimens were mounted. The count of ventral opisthosomal semiannuli starts from the first full semiannulus behind the genitalia. Dorsal opisthosomal semiannuli were counted from the first full semiannulus behind the middle of the prodorsal shield rear margin. When the length of cheliceral stylets is not given, it means that it was not possible to measure this character, since they were in a bundle that was immersed with other gnathosomal structures. Measurements were conducted according to de Lillo et al. (2010) except for the following: (1) the body length, which was measured from the tip of the frontal lobe to the rear end of the anal lobe, not considering pedipalps; (2) the sc tubercles space measurement (distance between the tubercles), not the sc setae distance; (3) empodium length, which includes its basal portion inserted into the tarsus. It was not possible to produce lateral drawings since all specimens were mounted in dorsoventral position. Similarly juveniles were collected only for N. colombiana, for which drawings and some measurements are presented. Micrographs were obtained using a digital system consisting of the phase and differential interference contrast microscope (Nikon Eclipse 80i) connected to a digital camera (Nikon DS-Ri 1, 12.7 mega pixels) which was in turn connected to a computer with NIS Elements software (Nikon). In addition to the new species descriptions, host plants, type localities and main morphological traits for all Notostrix and Propilus species were summarized in Tables 1 and 2, respectively. Information was based on original descriptions (text and drawings). Taxonomy Family Eriophyidae Nalepa, 1898 Genus Notostrix Keifer, 1963 Notostrix speciosa Reis & Navia sp. nov. (Figures 1–2) Differential diagnosis The new species is close to N. spinula Navia & Flechtmann, 2005 in the undivided 7-rayed empodia, in the coverflap with basal area granulated and distal area with longitudinal lines and in the general aspect of opisthosoma. However, it differs from N. spinula in the apically rounded frontal lobe (acuminate in N. spinula), in the prodorsal shield ornamentation with admedian lines (no lines in N. spinula), in the subtriangular female genital coverflap (subquadrangular in N. spinula), in the granulated coxal ornamentation (curved lines in N. spinula), in

the sc seta 5–6 µm long (2–3 µm long in N. spinula) and in the elongated microtubercles on ventral semiannuli (small rounded microtubercles in N. spinula). The new taxon is also similar to Notostrix longiseta Navia & Flechtmann, 2003 and to N. nasutiformes Gondim, Flechtmann & Moraes, 2000 in the number of empodial rays (7 rays), in the apically rounded frontal lobe, in the coverflap and coxal ornamentation basally granulated and with longitudinal lines in the distal area; however, it differs from both species in the prodorsal shield ornamentation (admedian lines and elongated cells in N. longiseta and only submarginal lines in N. nasutiformes) and from N. longiseta in the sc seta length (5–6 µm long in the new species, 20 µm long in N. longiseta).

Differential diagnosis Notostrix juma sp. nov. differs from all known species of this genus by the unique prodorsal shield ornamentation. This new species is similar to N. longiseta Navia & Flechtmann, 2003 and N. spinula Navia & Flechtmann, 2005 in the undivided 6–7-rayed empodia and in the female genital coverflap with basal area granulated or with dashes and distally with longitudinal radial lines. However, in addition to the prodorsal shield ornamentation N. juma differs from these species in the sc seta 5 µm long (17–20 µm in N. longiseta and 2–3 µm long in N. spinula). The new species is also similar to N. trifida Navia & Flechtmann, 2003 in the apically rounded frontal lobe and presence of admedian lines in the prodorsal shield, being

distinguished from this species by the tripartite empodium (undivided in the new species).

Description Female (n = 10). Body slender, elongate, 191 (174–200), 52 (51–65) wide; colour in life white-yellowish, with wax flakes along idiosoma.

Etymology The specific designation “juma” refers to the main and beautiful character of a famous Brazilian soap opera played in Pantanal, since the new species is also of a special beauty. Family Eriophyidae Nalepa, 1898 Genus Notostrix Keifer, 1963 Notostrix colombiana Reis and Navia sp. nov. (Figures 5–6)

Differential diagnosis The new species is close to Notostrix exigua Flechtmann, 1998 in the female genital coverflap with two rows of longitudinal lines or ribs. However it differs from this species in the sc seta 10 µm long (3–4 µm in N. exigua); in the empodium simple (tripartite in N. exigua), in the frontal lobe slightly pointed (more acute in N. exigua), in the higher number of dorso-opisthosomal semiannuli (45 in N. colombiana, 28 in N. exigua) and in the presence of microtubercles in the last opisthosoma dorsal semiannuli (absent in N. exigua). This species is the largest Notostrix so far known (N. colombiana 285 µm long; Notostrix butiae 256 µm long; Notostrix attenuate Keifer, 1963 250 µm long; Notostrix macrothrix Flechtmann & Moraes, 2013 234 µm long; N. spinula 230 µm long; N. miniseta Navia & Flechtmann, 2003 227 µm long; N. exigua 214 µm long).

Etymology

Family Phytoptidae Murray, 1877 Genus Propilus Keifer, 1975 Propilus flechtmanni Reis and Navia sp. nov. (Figures 7–8)

Differential diagnosis Propilus flechtmanni sp. nov. is distinctive in the smooth prodorsal shield and in the presence of a remarkable middorsal ridge on the opisthosoma. The new species is similar to Propilus bactris Reis & Navia, 2012, in shape and position of vertical external seta (ve). However, in the new species, vertical external seta is smaller (4 µm in


The specific designation “colombiana” refers to the country Colombia on which the species was found and also to its emblematic host plant, which is considered the national tree.

Remarks Type material Female holotype, 9 female and 10 male paratypes, from A. murumuru Mart., Guajará Mirim, Rondônia, Brazil, 10° 48′ 01.47″ S, 65° 18′ 28.83″ W, 9 September 2012, collected by D. Navia and F. Ferragut, on 6 microscope slides. Holotype and paratypes (11 specimens, 5 females and 6 males, on 3 microscope slides) deposited in the plant mite collection at “Embrapa Recursos Genéticos e Biotecnologia”, Brasília, DF, Brazil. Paratypes (8 specimens, 4 females and 4 males, on 2 microscope slides) also deposited in the collection at “Laboratório de Acarologia, Departamento de Agronomia, Universidade Federal Rural de Pernambuco”, Recife, Pernambuco, Brazil. Relation to host plant No damage symptoms were observed.

During this study, N. nasutiformes was collected from a new host plant, Syagrus flexuosa (Mart.) Becc., and a new locality, Pantanal Norte, Mato Grosso, Brazil, 16º 30′ 23″ S, 56º 40′ 34″ N, 16 June 2012, by D. Navia and F. Ferragut. Some morphological differences from original description were observed on studied specimens (41 females and 10 males on 17 microscopic slides): presence of slightly sinuous admedian lines on prodorsal shield; minute microtubercles on the last dorsal opisthosomal semiannuli. In the studied specimens, the presence of the palpal apical seta was observed.
