Scanning electron microscopy images of an adult male Psoroptes natalensis mite (A), showing the propodosomal and hysteronotal shields (B) as well as an adult female mite (C), showing the opisthosomal region (D).
Fig 2.
Illustration of a male Psoroptes natalensis mite showing body configuration and distribution of body appendages and setae.
A: dorsal surface showing the propodosomal and hysteronotal shields and propodosomal (si and se), metapodosomal (c1 and c2) and hysteronotal setae (d1, d2, e1, e2 and ps1). Outer opisthosomal setae (h2) and the inner one (h3) were spatulated. B: ventral surface showing the aedeagus located in the metapodosomal region, along with a pair of lateral cuticular pits, followed posteriorly with a pair of adanal suckers, propodosomal setae (1a), and metapodosomal setae (c3, cp, 4b, 3a and 4a).
Fig 3.
Illustration of a female Psoroptes natalensis mite showing body configuration and distribution of body appendages and setae.
A: dorsal surface showing the propodosomal plate and propodosomal (si and se), metapodosomal (c1, c2, cp, d1 and d2) and opisthosomal setae (e1, e2 and ps1). B: ventral surface showing the vulva as a transverse slit with two lateral limbs and supported with three pairs of setae; two lateral pairs (4b and g) and one pair behind the vulvar flap (4a), propodosomal setae (1a), metapodosomal setae (3a and 3c) and five pairs of perianal setae (ps2, ps3, h2, h3 and f2) around the subterminal anus.

Phylogenetic relationship of Psoroptes spp. based on partial sequences of the ITS2.
Evolutionary relationships of 22 taxa were inferred using the Neighbor-Joining method and Saitou and Nei distances, with the Otodectes cynotis (HQ728005) as the outgroup. Numbers at the internodes correspond to percent bootstrap values from 5,000 replicates.
