Ochrolitus
Sharp, 1889
Species Guides
1Ochrolitus is a of minute beetles in the Phalacridae, first described by Sharp in 1889. Members of this genus belong to the Phalacrinae, a group of small, often inconspicuous beetles associated with fungal . The genus is rarely encountered and poorly documented in the literature, with extremely limited observational records.

Identification
Ochrolitus can be distinguished from other Phalacridae by the combination of: small body size (likely under 3 mm based on norms); pale yellowish to ochreous coloration (suggested by the genus name, from Greek 'ochros' meaning pale yellow and 'litos' meaning smooth or plain); and presumably the compact, rounded body form characteristic of Phalacrinae. Definitive identification requires examination of male genitalia and detailed microsculpture patterns on the . Separation from the closely related genus Phalacrus depends on subtle differences in antennal club structure and pronotal shape.
Habitat
Inferred from -level associations: in Phalacridae are consistently found in with fungal growth, including decaying plant matter, moldy vegetation, and sporocarps of basidiomycete fungi. Specific microhabitat preferences for Ochrolitus remain undocumented.
Distribution
The has been documented from the Palearctic region based on original description material. Precise geographic range is unknown due to scarcity of records and potential misidentification with related genera.
Similar Taxa
- PhalacrusMost similar within Phalacrinae; shares compact body form and fungal associations. Ochrolitus differs in reportedly paler coloration and subtle structural features of the pronotum and , though these distinctions require microscopic verification.
- OlibrusAnother Phalacridae with overlapping size range. Olibrus generally exhibit more pronounced in antennal structure and darker coloration compared to the pale, relatively uniform appearance attributed to Ochrolitus.

Taxonomic obscurity
Ochrolitus represents one of the most poorly known within Phalacridae. The original description by Sharp (1889) has not been comprehensively revised, and modern taxonomic treatments rarely mention the genus. The single iNaturalist observation suggests contemporary detection is extremely rare, possibly due to genuine rarity, cryptic habits, or persistent confusion with Phalacrus and other genera.
Etymology
The name derives from Greek 'ochros' (pale yellow, ochre) and 'litos' (plain, smooth, or simple), presumably referencing the coloration and unadorned appearance of the type .
