) Pseudepiphallus rectangular, stouter, and shorter than in congeners, very wide laterally at base of rami, its basal anterior margin almost straight, lateral margin generally parallel, apex truncated, forming a short posterior plate, slightly concave dorsally, with a small median nodule. Rami short, but longer than half of pseudepiphallus length. Pseudepiphallic parameres strongly bent 90° in the middle, apex strongly sclerotized and forming two stout lobules. Ectophallic apodemes surpassing anterior margin of pseudepiphallic sclerite. Endophallic sclerite short, barely reaching anterior margin of pseudepiphallus, with thin posterior lateral arms and a very small medio-posterior expansion.
