Eusphalerum

***Eusphalerum*** er en gruppe (slekt) av biller som hører til underfamilien punktøyekortvinger (Omaliinae) i den store familien kortvinger (Staphylinidae). Disse små billene er vanlige å finne i blomster.

## Utseende
Små (gjerne 1,5-2,5 millimeter), mer eller mindre brunlige eller rødlige, brede, litt flate kortvinger. Disse billene er forholdsvis tynn-skallede (lite sklerotiserte), litt myke og skjøre. Antennene er tydelig tykkere mot spissen. Pronotum er mye bredere enn langt, omtrent trapesformet. Dekkvingene er lange til kortvinger å være, hos noen arter dekker de så godt som hele bakkroppen. Beina er ganske korte. Ved første øyekast kan disse artene minne om glansbiller (Nitidulidae), særlig fordi de som mange av disse lever på blomster.

## Levevis
*Eusphalerum*-artene finnes ofte tallrikt på blomster, særlig åpne, hvite blomsterklaser som rogn og mjødurt, der de spiser pollen.

## Systematisk oversikt

Navnet *Anthobium* har av og til blitt brukt på denne slekten, men det bør brukes om en annen slekt i Omaliinae.
