a) Measures: BODY: interantennal distance (IAD), interocular distance (IOD), anterior wing length (AWL); POSTOCULAR FLANGE: mesial width (MW), diagonal length (DL), and postocular spine length (SL). b) Landmarks in yellow.

PCA of the three Platyneuromus species.
Measurements of body and postocular flange are included for both sexes.
Fig 4.
Analysis of pairwise correlation.
Body measures are IAD, IOD, and AWL; postocular flange measures are MW, DL, and SL.

Allometric growth in P. honduranus.
The developmental strategies correspond to a divergent growth trajectory. Linear fit male MW = -0.528809 + 2.4817574*IAD; female MW = -0.219867 + 0.9724537* IAD.
Fig 8.
Allometric growth in P. soror.
The developmental strategies correspond to a divergent growth trajectory. Linear fit male MW = -0.729184 + 2.2514065* IAD; female MW = -0.014324 + 0.6217066* IAD.
Fig 9.
Allometric growth in P. reflexus.
The developmental strategies correspond to a nearly parallel growth trajectory. Linear fit male MW = -0.023069 + 0.8791506* IAD; female MW = -0.34204 + 1.3501466* IAD.

Rate of allometric growth in the species of the genus Platyneuromus.
Fig 10.
ANOVAs between all traits in each species with respect to sex.
In the measures of body size there is a generally female-biased pattern of sexual size dimorphism, while in the POF measures, males are generally larger.
Fig 11.
Geometric morphometric regression between centroid size and Procrustes coordinates.
The lines show the fit of each species and the thin plate splines represent the Procrustes deformation of the POF from the smallest females (open circles) to the biggest males (closed circles). The POF is represented by six landmark coordinates.
