Diagnosis. Teulisna hreblayi is externally reminiscent of T. thomasi and T. quadrisignata but can be readily distinguished by the submarginal area of the forewing much less suffused with fuscous in both sexes. The male genital capsule of T. hreblayi differs from T. thomasi and T. quadrisignata in the broader dorsal section of the valva with a somewhat more convex dorsal margin, the lamella centralis bearing a robust spike-like process directed dorsally (it is thinner and directed more anteriorly in T. quadrisignata and vestigial in T. thomasi ), and the markedly shorter ventral lobe of the distal saccular process. The phallus of T. hreblayi is considerably longer and broader (in proportion to the genital capsule) than in similar congeners. In the vesica structure, the new species is most similar to T. quadrisignata but distinguished by the longer and broader main chamber, the larger, sack-like and more heavily granulose 1st proximal diverticulum directed anteriorly (it is rather utricular and directed ventrally in the congener), the 2nd proximal diverticulum lacking graniculi, the longer, broader and more heavily granulose 1st medial diverticulum, the lack of the 2nd medial diverticulum, the longer and broader distal diverticulum bearing a markedly longer cornutus, and the larger apical diverticulum. The female genitalia of T. hreblayi are most similar to T. thomasi , from which the former species differs clearly in the shorter ductus bursae with convex lateral margins, the shorter and rugose posterior section of the corpus bursae with a gelatinous ventral diverticulum posteriorly (it is absent in the congener), the somewhat broader and globular anterior section of the corpus bursae displaced laterally on the left side (it is sack-like and situated anteriorly in T. thomasi ), the longer signum, and the configuration of the appendix bursae, which in the new species is heavily sclerotised with a membranous apex, strongly elongate (longer than the corpus bursae), and has a dilated, semiglobular proximal section and a narrow, cylindrical and straight distal section whereas the appendix bursae of T. thomasi is sack-like and markedly shorter than the corpus bursae.

Distribution. The new species is currently known from eastern Nepal ( Huang et al. 2024).
