Other immature stages
Unknown.
Etymology
The epithet obtecta derives from the Latin obtegere (to cover up), alluding to the dorsum being completely covered with reticulate patterns.
Remarks
The new species resembles Mediolata pini (Canestrini) in having two setae on palp femur, genu I with two setae and aggenital shield bearing three pairs of setae. However, it can be distinguished from the latter by dorsal shields fused except the suranal shield, and dorsum differently ornamented. This species further resembles Mediolata oleariae Wood, 1971 in general appearance; however, it can be distinguished from the latter by trochanter IV with one seta (lacking in M. oleariae ), setal formula of femora: 4–4–2–1 (5–4–3– 1 in M. oleariae ), and setal formula of genua: 1+1 Κ –1–1–1 (3+1 Κ –3–1– 1 in M. oleariae ).
