Ovatametra gualeguay Bachmann, 1966

Figs. 21 , 22

Diagnosis. Body length 2.7–3.0 mm; minimum interocular distance 1.75 times the width of an eye; black marks on apterous mesonotum not united posteriorly; female abdominal mediotergites VI and VII each with a posterior tuft of short setae ( Bachmann 1966).

Comments. There is a high degree of variation of the mesonotal marks ( Fig. 21 ), which are commonly used to distinguish species in this genus. A revision of this and other genera of Neotropical Trepobatinae is being conducted by the first author to ensure a proper specific delimitation.
