Tsinilla
Heinrich, 1931
Species Guides
1Tsinilla is a of tortricid moths in the Olethreutinae, established by Heinrich in 1931. The genus contains seven described , most of which were described by Razowski and Wojtusiak between 2008 and 2011. Species are known from the Neotropical region, including Peru and Colombia. The genus is part of the diverse tortricid fauna of the Americas but remains poorly known in terms of and .

Identification
Tsinilla can be distinguished from other Olethreutinae by genitalic characters, particularly in the male valva and female sterigma, as detailed in the original descriptions by Razowski and Wojtusiak. External alone is insufficient for reliable identification; dissection and examination of genitalia are required. The genus lacks the prominent forewing pattern elements seen in some related genera such as Cydia or Grapholita.
Distribution
Neotropical region. Documented from Peru and Colombia based on recent taxonomic revisions. The type Tsinilla lineana was described from the United States (North Carolina), suggesting a broader distribution that may include the Nearctic region, though this requires verification.
Similar Taxa
- CydiaBoth are Olethreutinae with somewhat similar forewing shapes, but Cydia typically show more distinct forewing markings and different genitalic structures.
- GrapholitaSimilar overall size and wing shape, but Grapholita usually have more contrasting wing patterns and different male genitalia with distinct valva shape.

Taxonomic history
The was established by Heinrich in 1931 with Tsinilla lineana as the type . Most species were described much later by Razowski and Wojtusiak during their extensive work on Neotropical Tortricidae, with six of seven species described between 2008 and 2011. This pattern reflects the historically poor knowledge of Olethreutinae diversity in South America.
Research needs
Basic biological information including larval plants, stages, and precise geographic ranges are unknown for all . The larval of the type species Tsinilla lineana has never been documented despite being described over a century ago.
