									  | Adineta sp. 21,  lateral view, optical longitudinal transect, focus plane on the right side protrusion of the rostrum lamella. The arrowhead marks the   anterior rostrum lamella (aRL); the arrow marks the posterior rostrum lamella (pRL). CiF: ciliary field; HyC: hypodermis cells; LL: lower lip; Ra: rake blade; UL: upper lip. |

									  | Adineta sp. 21,  dorsoventral view, two aspects of the head. | 
									
									  | Left image: focus plane on the rake apparatus with NoUH: 4/4. Another morphotype with NoUH 4/4 is Adineta sp.8. The arrowheads point to two bundles of ?sensory? cilia. | 
									
									  | Right image: focus plane on the rostrum lamella with short sensory bristles. Anterior rostrum lamella width (aRLW, marked by double arrow) equals posterior rostrum lamella width (pRLW; delimited by arrowheads). This is different from other morphotypes; example see here: |

									  | Adineta sp. 21, two images of the foot and spurs. | 
									
									  | Left:  focus plane on the "triangular" spurs with interspace. (ratio IW : SBW≈ 1). The morphology (dimensions) of these spurs is different from the morphotype Adineta sp.8, which has the same NoUH. | 
									
									  | Right: focus plane on a slight notch between foot pseudosegment and bulbous spur-bearing pseudosegmment |
