Hyalospectra dierli sp. n.
Hyalospectra dierli  (holotype) |
 |
9-10mm.
The facies is typical of the western members of the genus, though the darker
markings are pale grey rather than fawn, and darker areas are brown-grey. The
fasciae are slightly more regular, transverse. The dark brown-grey marks are
few, diagnostically along the forewing costa and just distal to the hyaline
patch between M3 and M2, being an enlarged component of a postmedial row of
darker spots in the spaces. This row of marks is present on the hindwing, though
that between M3 and M2 is only slightly larger than the rest. The male genitalia
have the structures on the tegumen broad, rather rectangular, without long socii.
The valves are rather rounded, their interior processes consisting of two spurs
not seen in labi or altipustularia: in pustularia they
consist of long, slender spines, the left one twice the length of the right. The
saccus is broader, rounder than in these two species.
