Diagnosis.
Body predominantly yellow non-metallic, gastral tergites 1 and 4–7 yellow, tergites 2–3 brown; frons without cross-bands; mesoscutum and scutellum with very weak and small meshed reticulation (
Fig. 10
).
Description
(female). Length of body 0.9–1.0 mm. Scape and pedicel pale yellow, flagellum yellowishbrown. Frons, vertex and occiput yellow. Pronotum with anterior half white, posterior half yellow.

a. Frons reticulate with a sharp ridge in the interscrobal area. Frontal suture straight, bifurcating laterally, ventral arm slightly downcurved. Vertex reticulate with a strong oblique furrow between the anterior ocellus and each posterior ocelli (
Fig. 4
c). Occipital margin rounded. Ratios: HE/MS/W = 3.1/1.0/ 2.2; POL/OOL/POO = 3.0/2.2/1.0; WH/WT = 1.1.
Mesoscutum and scutellum with very weak and small meshed reticulation. Notauli visible in anterior fourth (

Biology remarks.
The parasitoid complex reared from the galls on
Machaerium milleflorum
is composed of three species;
Ablerus
sp. (
Aphelinidae
:
Azotinae
), an unidentified species of
Tetrastichinae
and
C. machaeriae
.
C. machaeriae
parasitized 34.5% of the collected galls.
Distribution.
Canopy of the Parque Natural Metropolitano, Provincia de
Panama
,
República de Panama
.
Identification.
This species belongs to the
C. auripunctata
-group (sensu
Hansson 2004
). With the key in
Hansson (2004)
, the female runs to couplet 60. To include
C. machaeriae
the key should be modified as follows:
Couplet 59, second alternative leads to 60a, not 60.
60a. Gaster yellow with tergites 2–3 yellowish-brown to pale brown...............
