Etymology.
This species is named in reference to the Biota/FAPESP Program. The main aim of this program is to survey and characterize the biodiversity of the State of São Paulo,
Brazil
.
Remarks.
This new species belongs to the
obtusus
species group, characterized by
Chant & McMurtry (2004a)
by having setae z2, z4, Z1, S2, S4 and S5 short/minute, approximately subequal; setae s4, Z4 and Z5 are prominent, usually but not always very elongate, sometimes whip-like, and by having the ventrianal shield of female pentagonal in shape, widest at the level of setae ZV2. Within the
obtusus
species group,
A
.
biotafapesp
sp. nov.
belongs to the
andersoni
species subgroup, by having the spermatheca with calyx bell-shaped with the length/ width ratio at the mid-point of the calyx <3:1. Only three species of the
andersoni
subspecies group have setae Z4 <60 µm and Z5 100–150 µm:
Amblyseius bellatulus
Tseng, 1983
,
A
.
impeltatus
Denmark
& Muma, 1973
and
A
.
tsugawai
Ehara, 1959
.
Amblyseius biotafapesp
sp. nov.
differs from
A
.
bellatulus
by having St IV 1.26 times as long and dorsal shield fully smooth; from
A
.
impeltatus
by having Z4 1.30 times as long, and from
A
.
tsugawai
by having St IV 0.78 times as long. In addtion this new species differs these three species by having the pair of pores in the ventri-anal shield of females posterior to JV2.
Amblyseius biotafapesp
sp. nov.
also resembles
A
.
bahiensis
Lofego, Moraes & McMurtry, 2000
,
A
.
igarassuensis
Gondim Jr. & Moraes, 2001
and
A
.
paulofariensis
Demite, Lofego & Feres, 2007
. It differs from
A
.
bahiensis
by the localization of pair of pores in the ventri-anal shield of females and males (posterior to JV2), not having striae in the ventri-anal shield of females and macrosetae Sge IV and Sti IV about 1.4 times as long; differs from females of
A
.
igarassuensis
by ratios z2/z4 and s4/Z4, 1.62 and 0.8, respectively, and by spermatheca bell-shaped and of relatively smaller size; and differs from females of
A
.
paulofariensis
by having Z5 and spermatheca about 1.5 times as long.
