  • Phalaenopsis Mite, Tenuipalpus Pacificus Baker (Arachnida: Acari: Tenuipalpidae)1 H
    EENY377 Phalaenopsis Mite, Tenuipalpus pacificus Baker (Arachnida: Acari: Tenuipalpidae)1 H. A. Denmark2 Introduction Pritchard (1949) refers to Tenuipalpus pacificus Baker as the phalaenopsis mite. This flat, red mite is one of the most destructive found on orchids under Florida greenhouse conditions. It feeds on the leaves of orchids but does not spin a web. Apparently it is an introduced species on orchids from the tropics. It can also be a pest of ferns. Distribution Tenuipalpus pacificus was described from specimens intercepted at Hoboken, New Jersey, from the Canal Zone on Phalaenopsis stuartiana in 1943 (Baker). The known distribution is Australia (New South Wales) (CSIRO 2004), Brazil (De Moraes and Freire 2001), Eng- land, Germany, Holland, Java, Panama, Philippines, Siam, South Africa, and the United States. In the United States, it has been recorded in California, Hawaii (Anonymous 2002), and Florida. It is probably Figure 1. Adult female Tenuipalpus pacificus Baker. found wherever orchids have been imported directly from South and Central America. Description The length of the adult female, including the rostrum, is 312 microns and 190 microns wide. The third terminal, palpal segment is small with one short, straight seta and one longer, slightly curved seta. These characters cannot be seen on unmounted specimens. The hysterosoma has four pairs of non-flagellate setae and one pair of flagellate 1.

Several researchers have recorded a high abundance of Tenuipalpus heveae Baker, 1945 (Acari, Tenuipalpidae) in rubber tree plantations from different regions of Brazil. Currently this species is considered a mite pest for this crop. Tenuipalpus heveae was described only from female specimens collected on rubber tree from Belterra, State of Pará, Brazil. Recently, male and immatures were described. However, the original description of the female does not provide essential information (e.g. drawings of the dorsal ornamentation, venter, leg chaetotaxy and setal measurements), and thus, it may be difficult to correctly identify the species. In this paper, we re- describe the female of T. heveae in a standardized form, based on the study of the type specimens deposited at the Smithsonian Institution - USNM Insect & Mite Collection, at the Collection of Acari DZSJRP, and specimens collected in rubber tree plantations from different regions of Brazil.

ABSTRACT — Tenuipalpus heveae Baker, 1945 was originally described from only female specimens collected on rubber trees from Belterra, State of Pará, Brazil. The original description does not provide enough key information essential for accurate and consistent species identification, and thus, it is difficult to correctly identify this species. In this paper, we redescribe the female, male and immatures of T. heveae, from type and newly collected material, and include additional novel data (e.g. dorsal and ventral ornamentation, leg chaetotaxy and setal measurements) in a standardized form. In addition, we describe Tenuipalpus vieirae n.

A new species, Acaricis urigersoni sp. nov., is here described and illustrated from leaves of Gahnia lacera (Cyperaceae) in Auckland, New Zealand. In this paper, we presented the ontogenetic changes in idiosomal and leg chaetotaxy from larva to adult. A key to the world species of Acaricis is also proposed. Key words: Flat mite, false spider mite, new species, Cyperaceae, Gahnia lacera, ontogenetic changes Introduction The Tenuipalpidae, commonly known as false spider mites or flat mites, has been considered as an under-explored family of plant-feeding mites of great economic importance (Gerson 2008). Recent increase in the interest in these mites was attributed to their biosecurity importance (as invasive species as well as vectors of virus diseases) and their use as model organisms to explore basic evolutionary questions such as sex determination and microorganism-mite interactions (Zhang 2010).

The genus Brevipalpus has over 300 species worldwide. The three most impor- tant agricultural pest species in the genus, Brevipalpus californicus (Banks), B. obovatus Donnadieu, and B. phoenicis (Geijskes), have been consistently confused and misidentified for more than 50 years. The present study provides a discussion of the characters and character states used to separate these mites. Low-temperature scanning electron microscopy and tradi- tional light microscopy techniques were used to illustrate the subtle morphological differences between these three species. Morphology of the dorsal propodosoma, opisthosoma, and leg chaetotaxy of all three species was examined and compared. The number of dorsal setae, the number of solenidia (omega) on tarsus II, and dorsal cuticular patterns were the most important characters in the identification of Brevipalpus species. B. phoenicis is similar to B. californicus in having two omega on tarsus leg II and different from B. obovatus which has only one omega on tarsus leg II and similar to B. obovatus in having only one pair of F setae (f3), but differing from B.
