 Macrogynoplax pulchra Ribeiro-Ferreira & Froehlich, 1999:134, figs. 7–13. Froehlich, 2003:133 (key).   
 Diagnosis. Body greenish yellow in life, but whitish in alcohol. Tergum ten of males without sensilla basiconica. The aedeagus lacks penial hooks and the apex of the tube is long and narrows distally. The paraproct has an acute tip with a well-developed subapical spine. The female subgenital plate is wide, covers sternum nine, and has a small transverse furrow along the posterior margin.   
 Redescription of male holotype. Body greenish yellow in life, whitish yellow in alcohol. Head light to dark yellow (similar to Fig. 4 of M. delicata), 1.1 mm long, 1.9 mm wide; frons light yellow with conspicuous M-shaped spots rather concolorous with the integument, spots located between the base of the antennae and anterior to the ocelli; ocelli separated by twice their width; maxillary and labial palpi dark to light yellow; scape, pedicel, and flagellum light yellow. Pronotum yellow to whitish (similar to Fig. 4 of M. delicata). Meso– and metanotum light yellow. Coxa and trochanter light yellow, femur and tibia light yellow, without spots. Fore– and hindwings completely hyaline (Fig. 7). Abdomen light yellow; cerci light yellow with large bristles pale brown. Sternum nine (Fig. 26) wider than long with large median lobe; hammer (Figs. 28–29) slightly rounded; paraproct (Fig. 30) wide at base, apex acute; subapical spine long and pointed. Tergum ten (Fig. 27) lacking sensilla basiconica. Penial armature (Figs. 31–33) lacking penial hooks and apex largely membranous and short.   
Female (Figs. 2). The original association is accepted; sternum eight wider than long covering sternum nine with small transverse, posterior groove (Fig. 34).  
 Variations. Length of male 7.1–9.6 mm; head 0.7–1.1 mm long, 1.4–1.7 mm wide; forewing 10.5–12.0 mm long, 3.4–4.1 wide; hindwing 9.4–10.3 mm long, 4.0– 4.4 mm wide.

 Condition of the holotype: Dissected abdomen in micro vial with glycerin, exuviae separate inside Eppendorf tube, rest of body separate in a glass vial, all inside a larger glass jar with alcohol.   
 Note. Original publication cites 25.iii.1987 as collection date, while specimen label reads 25.iii. 1988 in the handwriting of one of the authors (A.C. Ferreira-Ribeiro). The publication is most likely incorrect.
