Glandulariini

Diagnostic features include the presence of glandular pores on abdominal tergites (particularly tergites III–V), a compact body form with the pronotum narrower than the elytra at their base, and the characteristic pselaphine antennal structure with a loose, 3-segmented club. Distinguished from related tribes (e.g., Pselaphini, Tmesisternini) by the specific arrangement and structure of abdominal glands, which appear as distinct circular or oval pores. Male genitalia often asymmetrical and species-diagnostic. Examination typically requires high magnification (40–100×).

Primarily found in forest leaf litter, particularly in moist, shaded environments. Also occurs in moss, decaying wood, fungal fruiting bodies, and soil horizons rich in organic matter. Some species associated with ant nests (myrmecophily) or termite colonies. Habitat specificity varies by genus; many show preference for undisturbed, mature forest ecosystems.

Cosmopolitan distribution with highest diversity in tropical and subtropical regions. Well-represented in the Oriental, Neotropical, and Afrotropical realms. Present but less diverse in the Palearctic and Nearctic regions, where they extend into temperate forests. Some genera exhibit disjunct distributions suggesting ancient vicariance patterns.

Activity patterns poorly documented for most species. Adults likely present year-round in stable tropical habitats. In temperate regions, probably most active during spring and summer when moisture and decomposition rates are favorable. No confirmed mass emergence patterns or strong seasonal flight activity documented.

Complete metamorphosis (egg, larva, pupa, adult). Larvae poorly known and rarely collected; likely inhabit same microhabitats as adults. Developmental duration unknown for most species. No evidence of parental care. Multiple generations per year probable in tropical species; single or overlapping generations likely in temperate species.

Slow-moving, cryptic beetles that remain concealed in microhabitats. When disturbed, often feign death or retreat into crevices. Some species produce defensive secretions from abdominal glands. Ant-associated species may exhibit reduced locomotion and chemical integration with host colonies. No confirmed aggregative or social behaviors beyond potential mating aggregations.

Members contribute to decomposition processes in forest floor ecosystems. As micro-predators or scavengers, they likely feed on fungal hyphae, spores, or minute invertebrates in soil and litter, though specific dietary roles remain undocumented. Some species participate in complex ecological networks through associations with ants or termites.

No direct economic importance. Occasionally collected in ecological surveys and biodiversity assessments. Presence may serve as an indicator of intact forest floor communities and habitat continuity due to sensitivity to disturbance and microhabitat specificity. No known pest status or beneficial applications in agriculture or biocontrol.

• PselaphiniShares compact body form and antennal structure; distinguished by lacking prominent abdominal glandular pores and by different pronotal-elytral junction morphology.
• TmesisterniniSimilar size and habitat; separated by antennal club structure and absence of the characteristic glandular tergal pores of Glandulariini.
• BatrisiniOverlaps in size and distribution; Batrisini typically have more elongated bodies and different abdominal gland arrangements, often with modified tergite VIII in males.
