Cocoon.

Elongate, silk light tan externally and white internally, spun within the cocoon of its host (Fig. 2).

Host.

Caterpillars of Stenoma cathosiota ( Depressariidae) (Fig. 1A) on Roupala montana ( Proteaceae).

Etymology.

Heteropteron kidonoi is named in honor of Dr. Hiroshi Kidono (retired) of Japan International Collaboration Agency (JICA), who first came to ACG in 1992 and has since then, and hopefully many years more, been a major supporter of all aspects of ACG, ranging from financing to Hesperiidae taxonomy to female parataxonomists to international conservation biopolitics.

Diagnosis.

This new species differs from H. fasciipennis most obviously in having a yellowish orange (in older specimens occasionally somewhat brownish) mesosoma rather than mostly blackish. From H. hasegawai, described below, it can be distinguished by its slightly to significantly darker yellowish portions of the metasoma (Figs 3, 5A), more acutely pointed hypopygium tip (Fig. 5B), more numerous and differently arranged small spines on the mid tibia (Fig. 5C), and the dark tarsal arolia (Fig. 5D).
