Aedeagus (general view as in Namyatova et al., in press: fig. 22M) conjunctiva membranous; vesica with single small claw-shaped spicule; apical half of ductus seminis sclerotized, secondary gonopore placed near phallotheca mouth in repose; ductus seminis hooked apically (fig. 10P).

Genitalia: Dorsal labiate plate very small and transparent, as wide as distance between apodemes of second valvulae, without striations or membranous ridge medially; semicircular sclerite and sclerotized rings absent; lateral oviducts placed in posterior part; spermathecal gland attached near anterior margin (as in fig. 16G); dorsal labiate plate without distinct tubercles, without membranous lobe posteriorly (as in fig. 16B).

DISTRIBUTION: Borneo ( Sarawak), Philippines (Mindanao Is.) (fig. 21).

HOST PLANTS: Unknown.

ETYMOLOGY: The species is named after Robert Zuparko, curatorial assistant at the California Academy of Sciences, for loaning material of Felisacus .

DISCUSSION: Antennal segment IV is lost in both males and females. Felisacus zuparkoi is similar to F. longiceps and F. magnificus externally. Both those species differ from F. zuparkoi in the absence of the vesical spicules (fig. 10H, J) and the narrow outgrowth on the left paramere (fig. 12R, X). Felisacus longiceps also can be separated by the antennal segment II often yellow, and F. magnificus differs in the shape of the left paramere, with the apical part flattened (fig. 12X).

Felisacus zuparkoi is also similar to Felisacus ceylonicus and F. lindbergae in coloration (figs. 4, 5). F. ceylonicus differs from F. zuparkoi in having a swollen vertex behind the eyes and the narrow outgrowth on the left paramere (fig. 11S). Felisacus lindbergae can be separated by the labium reaching the posterior margin of the prosternum or slightly surpassing it and the outgrowth on the left paramere is short (fig. 12N).
