Greatest variations observed on the shape of the markings on the postclypeus where the T-shaped structure could be reduced to two isolated spots. Dorsal carina along the posterior edge of prothorax not interrupted in two specimens. Dark elongated spots on the mesinfraepisternum diffused in most specimens and missing in one paratype. Two paratypes with pale markings on the dorsum of S9 close to the posterior end of the segment. Ovipositor surpassing S10 in one specimen.

<paragraph pageId="0" pageNumber="129">This species is only known from female specimens as no males were able to be associated. One female was excluded from the type material as it generally resembles the paratypes, but has the following differences: (1) posterior edge of the middle lobe of prothorax with incision having bilobed shape, (2) elongated spot on mesinfraepisternum darker than other paratypes, (3) dorsum of S10 with a diffused longitudinal bar joining the posterior end of the segment enclosing two pale spots, (4) smaller size than paratypes: total length 30.5, abdomen 25.2, HW length 19.5.</paragraph>
