Key to Species of GLYPTAPIS

1. Mesoscutum with punctures approximately one­third ocellar diameter or less and well spaced (not nearly contiguous) (fig. 38); precoxal triangle bordered anteriorly by narrow, glabrous margin many times less than width of areolae............... 2

– Mesoscutum with punctures large, approximately one­half ocellar diameter, and nearly contiguous (fig. 31); precoxal triangle bordered anteriorly by wide glabrous margin at least 1.5 times width of areolae......... G. mirabilis Cockerell

2. Precoxal triangle containing distinct transverse ridges or striae to form a single, dorsoventral row of areolae............ 3

– Precoxal triangle without areolae (fig. 33)................... G. disareolata , n. sp.

3. Deep, crater­like punctures of scutellum not restricted to posterior two­thirds; metanotum with minute punctures separated by 2– 3 times puncture width................................ G. fuscula Cockerell

– Deep, crater­like punctures of scutellum restricted to posterior two­thirds; metanotum with small punctures densely packed, separated by puncture width or less.................... G. densopunctata , n. sp.
