Diagnosis: All members of Asthenocorini have an anteromedial tooth of the prosternum ( Fig. 17 ), except Indonaucoris gen. nov.

Comments: This predominantly Philippine clade is represented by the three former members of Sagocorini that were transferred to Naucorinae by Zettel (2007) and a tiny (5 mm length) Naucoris -like species from India at its root. For this strongly supported group (pp = 1.0, bs = 100), I propose the new tribe Asthenocorini and the small Naucoris -like species at the root is described here as Indonaucoris minutus sp. nov. (see description below).

Included taxa: This tribe contains three genera endemic to the Philippines: Asthenocoris , Philippinocoris and Stalocoris . Also included is Indonaucoris from Maharashtra, India.
