Wings entirely lightly infuscate, stigma dark brown but centrally pale.

Male. Unknown.

Etymology.

Named in honor of Joseph Lee Burrow, the world-class college football quarterback for the LSU Tigers and the 2019 Heisman Trophy winner.

Host(s).

Unknown.

Distribution.

Orientocardiochiles joeburrowi sp. nov., is known from only one female specimen collected from Wang Kelian, Malaysia, which is near the Thailand-Malaysia border (Fig. 4A, B ).

Notes.

Orientocardiochiles joeburrowi sp. nov., can be distinguished from O. nigrofasciatus sp. nov. due to the following diagnostic characters of the genus: i) forewing entirely lightly infuscate; ii) propodeum without short longitudinal carina anteriorly; iii) propodeal areola quadrate (kite-shaped); iv) hind tarsal claw pectinate with 10 teeth; v) hypopygium entirely sclerotized and without median enfold; vi) scapus entirely brown.
