Amblypalpus
Mitrofanov and Strunkova, 1978
Type
species:
Amblypalpus narsikulovi
Mitrofanov and Strunkova, 1978: 1097
, by monotypy.
Note.
The
type
specimen is not in the collection of Nikita Botanical Gardens and is likely inaccessible in the collection of Strunkova (A. Khaustov, pers. comm.).
Diagnosis.
Palps 3-segmented; palp tarsus with 1–2 terminal phaneres; anterior margin of prodorsum with broad flat projection extending medially and laterally over base of coxa I, or projection absent; opisthosoma with 7–8 pairs of setae (
c2, d2, e2, f2,
absent;
c1, f3
present or absent); dorsal setae fine; leg cuticle not heavily sculptured; genital and ventral shield weakly developed, or not at all defined; metapodal shields absent; 2 pairs of
ps
setae, anal plate poorly defined, setae
ps1
not on tubercle,
ps1
–
2
inserted longitudinally on anal plates; tibia I–II with 5 setae; tarsal claws uncinate, empodia pad-like. Spermatheca with at least 1 subterminal bulb.
Remarks.
Our expanded concept of
Amblypalpus
is tentative as no single synapomorphy defines the genus, but instead is defined by a combination of features. Phylogenetic work is necessary to examine broader relationships, but we note that many features (e.g., reduced palpal segments, loss of setae) are regressive. Therefore these mites may represent simplified forms of other brevipalpine and, perhaps, also tenuipalpine genera. Among the brevipalpine genera, they resemble
Terminalichus
most in having a three-segmented palp and weakly developed ventral and genital shields (Beard
et al.
2013). Of the tenuipalpine-like genera, they resemble the
Ultratenuipalpus quadrisetosus
group by sharing the oval body shape and two pairs of
ps
setae (Beard
et al.
2013), but differ by having weakly developed ventral and genital plates, fine dorsal setae and three palpal segments instead of four (although
U. aberrans
may have just three).
