Type material. female holotype, 5 female and 2 male paratypes, from Mauritia flexuosa L. ( Arecaceae ), Manaus, Amazonas, Brazil, 2º57’S 59º57’W, 29 September 2003, collected by D. Navia and R. B. Querino, on 2 microscopic preparations, in the collection of Laboratório de Quarentena Vegetal, Embrapa Recursos Genéticos e Biotecnologia, Brasilia, DF, Brazil and paratypes in the collection of Departamento de Entomologia, Fitopatologia e Zoologia Agrícola, Universidade de São Paulo, ESALQ, Piracicaba, São Paulo, Brazil.

Relation to host. Vagrants on inner surface of leaves causing no apparent damage.

Etymology. The specific designation spinula , from the Latin, feminine, diminutive spina, thorn, refers to the short, spinelike scapular seta.

Remarks. Notostrix spinula n. sp. is similar to N. jamaicae Keifer 1970 in the general aspect of the prodorsal shield including scapular seta but differs in the number of opisthosomal dorsal annuli (26 in the N. spinula n. sp., 36 in N. jamaicae ) and in the genitalia (as wide as long in N. spinula n. sp., wider than long in N. jamaicae ). It shares the general aspect of the epigynum with N. vasquezae Navia & Flechtmann 2003 , but differs in the frontal lobe of the prodorsal shield (acuminate in N. spinula n. sp., rounded in N. vasquezae ), in the scapular seta (very short, spinelike in N. spinula n. sp.; long, setiform in N. vasquezae ) and in the number of dorso­opisthosomal annuli (26 in N. spinula n. sp., 48 in N. vasquezae ).

Type material. female holotype, 5 female and 2 male paratypes, from Astrocaryum acaule Mart. (Arecaceae) , Manaus, Amazonas, Brazil, 2º57’S 59º57’W, 29 September 2003, collected by D. Navia and R. B. Querino, on 2 microscopic preparations, in the collection of Laboratório de Quarentena Vegetal, Embrapa Recursos Genéticos e Biotecnologia, Brasilia, DF, Brazil and paratypes in the collection of Departamento de Entomologia, Fitopatologia e Zoologia Agrícola, Universidade de São Paulo, ESALQ, Piracicaba, São Paulo, Brazil.

Relation to host. Mites are vagrants on inner surface of leaves causing no apparent damage. Colonies were observed protected under a dense layer of loose trichomes along the midrib.

Etymology. This species is named after Ranyse Querino Barbosa, Entomologist at Unimontes, Montes Claros, Minas Gerais, Brazil, in appreciation of her inestimable help in collecting this material.

Remarks. Palmiphytoptus barbosae n. sp. is the second species described in this genus. It differs from the type species, P. oculatus Navia & Flechtmann 2002 , in the fusiform body shape (elongate, vermiform in the type species), in presenting median and admedian lines on the prodorsal shield (central shield area not ornamented in P. oculatus ); in the absence of eye­like structures (present in P. oculatus ) and in smooth dorsoopisthosomal annuli (microtuberculated in P. oculatus ). Inadvertently Amrine et al. (2003, p.18) included the eye like structures, a specific character of the type species, as a generic character for Palmiphytoptus , in the key to genera.

Type material. female holotype, 4 female and 1 male paratypes, from Mauritia flexuosa L. ( Arecaceae ), Manaus, Amazonas, Brazil, 2º57’S 59º57’W, 29 September 2003, collected by D. Navia and R. Q. Barbosa, on 2 microscopic preparations, in the collection of Laboratório de Quarentena Vegetal, Embrapa Recursos Genéticos e Biotecnologia, Brasilia, DF, Brazil and paratypes in the collection of Departamento de Entomologia, Fitopatologia e Zoologia Agrícola, Universidade de São Paulo, ESALQ, Piracicaba, São Paulo, Brazil.

Relation to host. Mites are vagrants on inner surface of leaves, along midribs, causing no apparent damage.

Etymology. The specific designation alternatus , from the Latin, alternating, refers to the alternating shorter and longer lateral expansions of the dorsal opisthosomal annuli.

Remarks. Propilus alternatus n. sp. is distinct in presenting alternating short and long lateral projections on the dorso opisthosoma annuli. In other described species these projections are of uniform size, either with or without prominent spines.
