Definition
Acalyptris rotundus is a species of moth in the family Nepticulidae, a group of very small lepidopterans known primarily for their leaf‑mining larval habits.
Overview
The species was formally described in 2002 by entomologists Rimantas Puplesis and Arūnas Diškus. As a member of the genus Acalyptris, it is part of a worldwide assemblage of micro‑moths that typically have a wingspan of only a few millimetres and exhibit intricate wing patterns. The precise geographic distribution of A. rotundus is limited in the published literature; available records indicate it occurs in the region where it was originally collected, but comprehensive range data are not readily accessible.
Etymology / Origin
The generic name Acalyptris derives from Greek roots: “a‑” (without) and “kalyptē” (cover or veil), referencing the absence of a particular wing covering structure present in related taxa. The specific epithet rotundus is Latin for “round” or “circular,” likely alluding to a morphological feature observed by the describers, such as the shape of a genital structure or wing pattern element.
Characteristics
- Taxonomic placement: Order Lepidoptera, family Nepticulidae, genus Acalyptris.
- Size: As typical for Nepticulidae, adult moths are minute, with an estimated wingspan of 3–5 mm.
- Morphology: Detailed morphological description, including wing coloration, patterning, and genitalia structure, is provided in the original species description (Puplesis & Diškus, 2002). Accurate information on these characteristics is not confirmed here without direct citation of that work.
- Life history: Larvae of Acalyptris species are leaf miners, creating characteristic tunnels within the leaf tissue of their host plants. The specific host plant(s) for A. rotundus have not been documented in widely available sources.
