Definition: Cyatholaiminae. Very close to Cyatholaimus. Cuticle with transverse striae bearing rows of punctations. Amphids spiral, situated just behind level of base of stoma. Head not offset, rather rounded in front, with 6 indistinct lips each with a small apical papilla. At base of lips a circlet of 10 cephalic setae,2 lateral, 4 subdorsal and 4 subventral. Stoma rather funnel-shaped, with a prominent dorsal tooth medially placed and 1 or 2 smaller subventral teeth situated futher back. Oesophagus cylindrical for the most part but slightly swollen and rounded terminally forming a pseudo-bulb. Tail tapering to end, caudal glands and terminal duct present. Vulva equatorial; gonads paired, opposed, reflexed. The male of A. granulata (Cobb) with paired spicules and a large gubernaculum about 2/3 as long as spicules and bearing large lateral expansions.

Species List:

TOP Notes: Cobb (1913) mentions the species A. minima = A. ruricola, is probably found in all parts of the world. He says he knows of species from Australia, Fiji, and various parts of the United States. Nannonchus granulatus = A. granulata was found about the roots of aquatic plants by the Potomac River, Arlington, Virginia. He mentions another species found in Long Key, Florida.

We have recovered Achromadora spp. in low numbers from soils of Nine-mile Prairie and Konza Prairie.
