Galendromimus multipoculi  n. sp.

( Fig. 1View FIGURE 1)

DIAGNOSIS: This new species differs from other species in the genus by having seta Z 1 at about the same level or slightly posterior to the level of setae J 2 and by its "pits" on the central region of the dorsal shield. It further differs from Galendromimus alveolaris (DeLeon, 1957)  by the long peritreme, from Galendromimus paulista Zacarias & Moraes, 2001  by the presence of J 2 and from Galendromimus borinquensis DeLeon, 1965  by the presence of J 2 and JV 3, by the absence of JV 4 and ZV 3 and by the shape of the spermatheca.

FEMALE (8 specimens).

With two pairs of metapodal shields. Ventrianal shield with 4 pairs of preanal setae and a pair of pores; length of shield 86 (79­92), width at level of ZV 2 48 (39­51), width at level of anus 53 (49­56). Setae JV 5 and ZV 1 on the integument surrounding ventrianal shield; JV 5 smooth.

Chelicera ­ Movable digit 21 (21­22), with 1 tooth; fixed digit 19 (18­21), with 2 teeth.

Spermatheca ­ Calyx tubular­saccular 20 (18­22) long, well or slightly sclerotized in different specimens. Major duct broad “bladder­like” on most specimens.

Legs ­ Macrosetae absent.

Peritreme ­ Extending anteriorly almost to j 1.

Venter ­ Ventral shields smooth, except for a few diagonal striae laterally and posteriorly on the ventrianal shield. Distances between St 1 ­St 3 57 (54­59), St 2 ­St 2 44 (43­ 45) and St 5 ­St 5 27 (25­28). Ventrianal shield with 5 pairs of setae in addition to perianals and a pair of pores; length of shield 91 (79­114), width at level of anterior angles 91 (71­ 112).

Legs ­ Macrosetae absent.

TYPE MATERIAL: Holotype female, allotype male, 4 paratype females and 2 paratype males, along Ribeira de Iguape River, Iguape, State of São Paulo, Brazil, from Inga uruguensis Hook & Arn.  ( Mimosaceae  ), M.S. Zacarias, deposited at Universidade de São Paulo, Escola Superior de Agricultura Luiz de Queiroz, Departamento de Entomologia, Fitopatologia e Zoologia Agrícola, Piracicaba­SP, Brazil. Three paratype females and 1 paratype male, same collection data as holotype, deposited at United States National Museum of Natural History, in the Florida State Collection of Arthropods, Entomology Section, Division of Plant Industry, Gainesville, Florida, USA.

ETYMOLOGY ­ The epithet multipoculi  refers to the presence of several "pits" on the central region of the dorsal shield of adult males and females.

REMARKS: The seta laterad to J 2 is identified as Z 1 despite its somewhat posterior position because of its position anterior to lyrifissure idS 1; concurrently, this interpretation is consistent with that for other species of Galendromimus  .

Chant & McMurtry (1994) characterized the mites in the genus Galendromimus  by a combination of the following characteristics: presence of setae s 6 and Z 1; absence of setae z 3, S 2, S 4 and R 1; setae Z 4 and Z 5 elongate, thick and strongly serrated. Additional characteristics of the known members of this genus are the absence of leg macrosetae and the presence or absence of setae J 2 and S 5. Two subgenera are recognized in this genus ( Chant & McMurtry, 1994), Galendromimus Muma  and Nothoseius DeLeon  , the former with 5 (including the new species here described) and the second with 1 species. The species here described fits the description of the former subgenus.

Galendromimus paulista  and G. borinquensis  are the only Typhlodrominae  known to lack seta J 2. G. paulista  and G. sanctus DeLeon, 1967  are the most hypotrichous species in this subfamily, with 16 pairs of dorsal setae (setal pattern 11 D: 5 B/JV­ 4;ZV­ 3).

Species of Galendromimus  . have been found on cultivated and wild low growing plants, vines and trees. They seem to be relatively rare. Nothing is known about the biology of those species.

A key is subsequently provided to help the separation of the species of Galendromimus  known to date. G. paulista  does not conform to either of the subgenera or species groups defined by Chant & McMurtry (1994); therefore, the proposed key omits those taxonomic groupings.
