The male of Lasioseius jorgeamadoi Santos and Argolo, 2018 is described based on specimens collected from buds of Theobroma cacao L. (Malvaceae) in Ilhéus, Bahia state, Brazil, representing the first characterization of males of this species.

Agricultural pests can cause direct damage to crops, including chlorosis, loss of vigor, defoliation, and wilting. In addition, they can also indirectly damage plants, such as by transmitting pathogenic micro-organisms while feeding on plant tissues, affecting the productivity and quality of crops and interfering with agricultural production. Among...

Background Members of the Acari order, commonly known as mites, play a significant role as agricultural pests. Among these, the Tetranychidae family stands out due to its remarkable diversity, surrounding approximately 1200 species capable of infesting over 4000 plant species. By feeding on plant tissues, these mites directly harm crops and can als...

The flat mite Tenuipalpus uvae De Leon, 1962 (Acari: Tenuipalpidae) is restricted to the Americas. The only available descriptions of this mite are based on the holotype and 12 paratype females and nymphs from Mexico. This paper focuses on redescribing the species based on the paratypes and new material from Florida (USA) and Brazil. Additionally,...

Two new diptilomiopid mite species of the genus Davisella Amrine, Stasny et Flechtmann are described from arboreal Meliaceae of economic potential from Bahia state, Northeastern Brazil—Davisella toonae sp. nov. from the exotic tree Toona ciliata M. Roem., and Davisella cedrelae sp. nov. from the native tree Cedrela odorata L. The two new species ar...

Tenuipalpidae (Trombidiformes: Tetranychoidea) is an economically important family of plant-feeding mites. The family has approximately 1,100 described species in 41 genera with worldwide distribution. Currently, 40 species of Tenuipalpidae have been recorded from Brazil, and prior to this study only 11 were known from Bahia state. Five new species...

Until now, Serraseius Moraes, Barbosa and Castro was a monotypic genus represented by Serraseius caicara Moraes, Barbosa and Castro, found in a fragment of the Atlantic Forest of the state of São Paulo, southeastern Brazil. This paper describes the second species of the genus, Serraseius nordestinus Araújo and Oliveira sp. nov., found in a fragment...

The cacao bud mite, Aceria reyesi (Nuzzaci), has been identified as the causal agent of the ‘engurruñadera del cacao’, characterized by the apparent accumulation of stipules on the buds, followed by die-back, with premature fall of leaves, shortening of internodes and proliferation of lateral branches, or witches’-broom, resulting in production los...

Tenuipalpus panici De Leon was originally described from female specimens collected on Panicum maximum Jacq. (Poaceae) from South of Baranquetas, Puerto Rico. In this paper, we redescribe the female of T. panici based on the holotype and on specimens newly collected in Brazil. It is the first record of the species in South America. Females, nymphs...

Predictive models based on diagrammatic scales of damage have been developed to estimate the population density of Aceria guerreronis, an important coconut pest. Steneotarsonemus concavuscutum colonizes the same habitat as A. guerreronis and causes similar lesions on fruits. The present study aims to evaluate the possibility of using predictive mod...

Fifteen species of Agistemus Summers were previously reported from Brazil. Herein, Agistemus bahiensis sp. nov. is described and illustrated from specimens collected on Annona muricata L. (Annonaceae), Euterpe oleracea Mart. and Polyandrococos caudescens (Mart.) Barb. Rodr. (Arecaceae) at the Southern Coastal Region of the state of Bahia, Brazil, b...

Many mite species disperse via the air. However, most methods described for the study of aerial dispersal have some limitations in the collection and/or recovery of mites that could be improved. The aim of this study was to describe a rotatory funnel-shaped collector that directs the wind to adhesive surfaces covered with a glycerin-based solution....

Of the 35 species of Premicrodispus described, only P. adjacens (Mahunka, 1969a) was recorded in the Neotropical region, specifically from Brazil. In the present paper, we describe a new species of Premicrodispus (P.) Cross, 1965 (Acari: Heterostigmatina: Microdispidae) from Brazil. An identification key to the subgenera and species of Premicrodisp...

The female, male and larva of a new species of Scutacarus Gros, 1845 (Acari: Heterostigmatina: Scutacaridae) and male and larva of Petalomium megasolenidiatum Silva, Khaustov & Oliveira, 2018a (Neopygmephoridae) are described. These mites were found associated with Camponotus cingulatus Mayr, 1862 (Hymenoptera: Formicidae) in the state of Bahia, No...

A new species of Tenuipalpus Donnadieu (Acari: Tenuipalpidae), Tenuipalpus odoratus Souza, Castro & Oliveira sp. nov., is described from females, males, deutonymphs, protonymphs and larvae collected on Cedrela odorata L. (Meliaceae) from Ilhéus, Bahia, Brazil. A proposed ontogeny of leg chaetotaxy is also included.

The present work describes the male of Cocoseius elsalvador Denmark and Andrews based on specimens collected in Brazil, representing the first characterization of a male of this genus.

Two new species of myrmecophilous mites of the superfamily Pygmephoroidea (Acari: Heterostigmatina) are described from ants collected in dry cacao fruits in a plantation in Ilhéus, Bahia, Brazil. Petalomium braziliensis sp.nov. (Neopygmephoridae) from workers of Odontomachus haematodus (Linnaeus, 1758), and Caesarodispus delabiei sp.nov. (Microdisp...

Mites of the family Tarsonemidae (Acari: Prostigmata) exhibit a great diversity of feeding habits including fungivorous, algivorous, plant feeders, and predatory of other mites, as parasitoids and parasites are kinds of symbionts of other insects. They also have a considerable diversity of morphological structures, including the shape and structure...

Neopilizetes is a genus of the oribatid mite family Galumnidae that was first characterized by having well-developed setae, a dorsosejugal suture, and raised striae on the prodorsum and notogaster. It was proposed to accommodate Pilizetes neotropicus Balogh & Mahunka 1978 from Brazil—the only supposed Pilizetes species known outside the Ethiopian R...

A new species of Petalomium Cross 1965 (Acari: Heterostigmatina: Neopygmephoridae) with a very large palpal solenidion is described. It was found attached to workers of an ant, Camponotus cingulatus Mayr 1862 (Hymenoptera: Formicidae) in the state of Bahia, Northeastern Brazil. The inclusion of the new species in Petalomium is discussed. A key to a...

Until now the mite genus Cosmolaelps Berlese was represented in Brazil by eleven species. A new species, based on adults collected exclusively from the brood of the ponerine ant Neoponera inversa (Smith) (Hymenoptera: Formicidae) is described. Colonies of this ant were found in dried cocoa pods fallen on the floor of a cocoa tree plantation in sout...

The cultivation of cocoa is an activity of great importance in the world, in Brazil and in the State of Bahia, the main national producer. The cocoa cultivation is usually planted in the Atlantic rainforest, biome which is the index of high temperature and precipitation. This biome is considered to be plant inhabiting taxa, apparently with preferen...

Licneremaeus braziliensis sp.nov. is described and illustrated based on female specimens collected from palm leaflets (Arecaceae) in Ilhéus, state of Bahia, northeastern Brazil. This is the first species of the genus described from this country. A dichotomous key for identification of all known species of Licneremaeus is proposed.

A new species of Petalomium Cross 1965 (Acari: Heterostigmatina: Neopygmephoridae) is described. This mite was found associated (phoresy) with workers of an ant, Neoponera verenae (Forel 1922) (Hymenoptera: Formicidae), in several localities in the state of Bahia, Northeastern Brazil. This is the first record of the genus in South America. A closel...

Two new cunaxid mite species, namely Scutopalus acaraje Rocha & Argolo n. sp. and Armascirus raulzito Rocha & Argolo n. sp., are described and illustrated from leaves of different plants of economic and ornamental importance of Bahia state, Northeastern Brazil. This is the first record of Scutopalus for that state.

Due to the expansion of the tropical flower agribusiness in the southern coastal region of Bahia State, Brazil, and the lack of studies on mites associated to these cultures in the region, mite surveys were conducted from September 2006 to June 2007 in 34 species/cultivars of ornamental plants of the families Costaceae, Heliconiaceae, Musaceae and...
