Integument.
Colour white-Yellow. Surface of bodY covered with fine punctation.
Prodorsum
(
Figs 9, 10
). Distinct lateral carinae and sigillar fields. Sensilli short with thin pedicel and swollen head, rounded in lateral aspect and fusiform in dorsal aspect. Prodorsal setae short, fine, attenuate, interlamellar setae distinctlY longer than lamellar and rostral setae.

Remarks: The new species is distinguishable from congeners by the presence of smooth, attenuate setae on its body. It is similar to the Brazilian species
Hoplophthiracarus tryssos
Niedbała,
2004
in size of bodY, length of lateral carinae on the prodorsum, and size and length of notogastral setae, but is distinguishable by the differences in length of the interlamellar and lamellar setae, longer setae on the anoadanal plates, and especially by the unusual position of vestigial setae
f
2
and the different arrangement of genital setae 4+2:3 (three setae in progenital position), versus 4:5 (five setae in progenital position in
H. tryssos
) (
Niedbała 2004
).
