Previous authors recognized the genus using the combination of the following homoplasious characters: preoccipital carina present, paraocular angle obtuse (absent), anterior border of mesoscutum often narrowed, and inner metatibial spur pectinate. The genus as understood herein, includes species that do not agree with this combination of characters, some of which have the preoccipital carina absent/faint to strongly carinate/ lamellate, paraocular angle variable from obtuse (absent) to forming a right angle, and inner metatibial spur pectinate but variable in shape and number of teeth.
Diagnosis
The genus
Neocorynura
in the present sense is well supported by the following putative synapomorphies and by the combination of some additional characters.
The synapomorphies for the genus include: a labral process on anterior margin, metabasitibial plate elongated, sometimes covered with setae; and the pores on the surface of the galea uniformly distributed.
Some other characters that in combination help in recognizing the genus include, in the females: integument of interantennal area imbricate and punctate, second submarginal cell wider than long, mandible mostly dark, sometimes with clear apex, mesotibial spur almost straight, first labial palpomere as long as the combined lengths of the following two, and glossa elongate and narrowly pointed. In males: dorsal surface of volsella acute or with hump, pores on S5 uniformly distributed across entire surface, and the posterior margin of T6 rounded.

diversity will be presented in a forthcoming contribution (SmithPardo, in prep.).
The unification of these genera requires some minor modifications to the generic keys provided by
Engel (2000)
and
Michener (2000)
. These alterations are as follows: In Engels (2000) key to females the first half of couplet 24 should read
Neocorynura
(changed from
Andinaugochlora
), couplet 26 can be removed entirely, and the second half of couplet 30 should read
Neocorynura
(changed from
Neocorynurella
). In Engels (2000) key to males the first half of couplet 27 should read
Neocorynura
(changed from
Andinaugochlora
and
Neocorynurella
), and couplet 28 can be removed entirely. In Micheners (2000) key to females the first half of couplet 23 should read
Neocorynura
(
N. joannisi
species group), and the second half of couplet 27 should read
Neocorynura
(
N. seeleyi
species group). In Micheners (2000) key to males the second half of couplet 21 should read
Neocorynura
(
N. seeleyi
species group), and the first part of couplet 25 should read
Neocorynura
(
N. joannisi
species group).
