Morphology and Anatomy:

photomicrographs by Howard Ferris and Sam Woo, UC Davis	Lip region with projecting probolae which are morphologically different among the species. Stoma wall often appears distinctly separated into thickened component regions called rhabdions. Cheilostom wide, by a funnel-shaped or narrow posterior part.
Acrobeloides male tail; spicules and gubernaculum

Distribution:

Widely distributed, world-wide.

Feeding:

Bacteria.  Populations of Acrobeloides sp. were successfully established on several bacteria species (Wood, 1973).

Biology and Ecology:

 Bhat et al (2023) reviewed reports of the association of some Acrobeloides species with insects. They noted that several species have been isolated from soil samples using the Galleria soil baiting technique (Bedding & Akhurst, 1975). Other arthropods, molluscs and annelids have been reported infested with Acrobeloides spp. Some associations with invertebrates are reported to be phoretic and necronemic ( Hao et al., 2010).

 The contributions of Acrobeloides spp. to soil nutrient cycling and mineralizationof organic forms of nitrogen are well documented (Anderson et al., 1981; Ferris et al., 1995 1997)
