Identification
Members of Lycostomus can be distinguished from other lycid by genitalic and antennal characters. The specific epithet "sagittatus" (arrow-shaped) likely refers to a distinctive morphological feature, though the exact diagnostic characters for this remain undocumented in available sources. Net-winged beetles in general are recognized by their soft, flexible with prominent reticulate venation that creates a net-like appearance, and many species exhibit orange, red, or yellow coloration warning of chemical defenses.
Distribution
Known from only two iNaturalist observations; specific locality data not provided in available sources. The Lycostomus has representatives in various regions, but precise geographic range for this cannot be determined from current documentation.
Similar Taxa
- Other Lycidae generaAll net-winged beetles share the characteristic reticulate elytral venation and soft-bodied form, requiring careful examination of antennal structure and male genitalia for definitive generic identification.

Taxonomic note
The Lycostomus is part of the diverse net-winged beetle Lycidae, which contains over 4,600 described globally. Many lycid species remain poorly known due to their secretive habits and the need for specialized dissection techniques for accurate identification.
Data limitations
This is represented by minimal occurrence data. The two iNaturalist observations constitute the only documented records located, and no published species description or revision was found in available sources. The name suggests formal description exists in primary taxonomic literature not accessed here.
