Calohypsibius ornatus (Richters, 1900) - No Common Name



SEM by Diane Nelson
Taxonomy
Class: EutardigradaOrder: Parachela Family: Calohypsibiidae Checklist Number: 1080.0 Synonym: Hypsibius (Calohypsibius) armatus Bartos, 1938, Hypsibius (Calohypsibius) intermedius Mihelcic, 1939,
Taxonomic Comments: This species is extremely variable morphologically (see Bartos 1940). Some DNA data is available for C. ornatus but not for N.Am. populations.
Species Notes: Terrestrial. Often reported from high elevation sights throughout Europe and beyond. Appears cosmopolitan but might be cryptic species cluster. Arguably the most beautiful of all eutardigrades.
Identification
Online resources:Online Photographs: Google, GBIF                                                                                 
Species Description: Eye spots absent: in the position which they occupy, there are instead two papillae. On the dorsum and on a good portion of the lateral surface are 8 transverse rows of cuticular spines or thorns (from 8 to 12 per row); the first transverse row is situated with the fourth pair and has particularly long spines. The cephalic region bears rounded papillae, similar to small knobs, and these papillae are also found dorsally and laterally, between the rows of spines. Buccal tube very narrow, pharynx oval with apophyses and 2 macroplacoids (rounded granules); lacking microplacoid; doubleclaws of each leg of about equal size and Calohypsibius type appearance.
Ramazzotti & Maucci 1983
Body Length: Up to 180 microns.
Key Characters: In Calophybius the primary claws are rigidly attached to the secondaries and the buccal tube is very thin with no ventral lamina. In this species dorsal cuticle beautifully sculptured with 8 rows of long spines.
Key Character Images
ID Requirements: Identifiable only by close inspection of key characters or by DNA analysis.
