Thosea medialis sp. n.
The facies is as in rotundata but with the dark diffuse medial band from
the dorsum to the discal spot more intense. In the male genitalia the aedeagus
lacks a small apical lobe, the furca arms are slender, longer than in borneensis
and gently, evenly curved. The valve apex is simply acute and relatively
symmetrical, slightly constricted just distal to the sacculus. The female
tentatively assigned to the species has the eighth segment well developed as in borneensis.
