234587BCFF86FFF052A026F4FBA6FB1D.taxon	etymology	Etymology. The name quetzalli is translated from Nahuatl as ‘ precious’ or ‘ beautiful’, and in turn gives its name to the astonishing quetzal (Pharomachrus mocinno), whose metallic green color and long tail feathers create an exceptional resemblance to the coloration and long adanal setae of this species of Ommatocepheus.	en	Tobar, Harol Revelo, Martínez, Pablo A., Palacios-Vargas, José G., Colina, Gabriel Otero- (2025): New species of oribatid mites (Acari, Oribatida) of the genera Ommatocepheus (Cepheusidae) and Eremella (Eremellidae) from Mexico.

234587BCFF86FFF052A026F4FBA6FB1D.taxon	discussion	Remarks: The new species resembles O. clavatus japonicus Aoki, 1974 by the shape of the notogastral setae and the size of the ad 1 – 2 setae; however, it differs in the shape of the interlamellar seta (claviform vs. rod-shaped) and in the size of the ad 3 seta (short vs. long). Also, it shows similarities with O. ocellatus (Michael, 1882) by the ornamentation of the notogaster and shape of notogastral setae, but differs in the size of the adanal setae (short vs long), shape of the interlamellar seta (lanceolate vs rod-shaped) and thickness of the lamellar protrusions (similar thickness to lamellar setae vs thicker than lamellar setae). Ommatocepheus quetzalli is, along with O. reticulatus, the largest known species, exceeding the others in length by 7 to 20 %.	en	Tobar, Harol Revelo, Martínez, Pablo A., Palacios-Vargas, José G., Colina, Gabriel Otero- (2025): New species of oribatid mites (Acari, Oribatida) of the genera Ommatocepheus (Cepheusidae) and Eremella (Eremellidae) from Mexico.

Smooth, microgranules of cerotegument arranged on body; ventral plate strongly striated. Dense accumulation of cerotegument and detritus on scalps, making difficult to observe setae from earlier stages of development. Prodorsum (Figure 21). Rostrum with slight rounded projection; rostral setae (27) (Figure 23) setiform, arising in apophyses; lamellar setae (118 × 100) (Figure 25) lamellate, leaf-shaped with slightly wavy margins, six or seven veins arising near seta insertion and divided distally; interlamellar seta (65) filiform, with lateral barbulations and arranged on small apophyses; bothridial seta (14) (Figure 22) small, setiform, with scattered spines and curved at the base; bothridium reduced to a bothridial scale, arranged inferior to bothridial seta; exobothridial seta (11) setiform, straight, smooth. A transverse costula arises from the bothridia and passes through the interlamellar setae, mediumdeep longitudinal depression is formed posterior to this and rises anteriorly, showing a short canal. Gastronotic region. Typically eupheredermous (Grandjean 1954; Woas 1990). Median region of the sejugal border with an apophysis (14 length, 13 diameter) (Figures 21, 24) projecting upward, covered with cerotegument granules (in dorsal view it has the appearance of a pollen granule).

Anal (19) and adanal (29) setae similar in shape to genital setae, adanal setae appear soladiate to small apophyses. Legs. Tarsi monodactylous.	en	Tobar, Harol Revelo, Martínez, Pablo A., Palacios-Vargas, José G., Colina, Gabriel Otero- (2025): New species of oribatid mites (Acari, Oribatida) of the genera Ommatocepheus (Cepheusidae) and Eremella (Eremellidae) from Mexico.

234587BCFF86FFF052A026F4FBA6FB1D.taxon	discussion	Remarks: The immatures of Ommatocepheus along with those of Conoppia palmicinctum (Michael, 1880) are distinguished from other species of the family by the widened shape of the notogastral setae of the nymphs (Colloff 2023; Michael 1880, 1882). Although with the caution of having studied only one tritonymph of O. quetzalli, it is important to compare it with the tritonymph of O. ocellatus: the immatures of the two species resemble each other in the shape of the bothridial and exobothridial setae, the size difference of the c 2 seta compared to the remaining notogastral setae, and the presence of a depression posterior to the interlamellar setae (see Travé 1963: Figure 24, 50). However, the tritonymph of O. quetzalli differs in the shape of the interlamellar setae (filiform vs claviform), c 1 setae (flabellate vs bacilliform), venation of the notogastral and lamellar setae (six or seven longitudinal veins vs multiple longitudinal veins interconnected like a spider web), presence of an apophysis in the sejugal region vs absence, and the shape of the rostral setae (setiform vs filiform). In figure 7 of Michael (1880) and figure 3 of Ritchers (1900) of O. ocellatus, a lamellate seta is shown inserted laterally on the prodorsum, almost at the level of the interlamellar setae, we assume this is an incorrect placement of the c 2 seta.	en	Tobar, Harol Revelo, Martínez, Pablo A., Palacios-Vargas, José G., Colina, Gabriel Otero- (2025): New species of oribatid mites (Acari, Oribatida) of the genera Ommatocepheus (Cepheusidae) and Eremella (Eremellidae) from Mexico.

234587BCFF8EFFF652A024EAFE5DFE75.taxon	discussion	Remarks: The new species resembles E. (Licnocepheus) matildebellae Mahunka & Palacios Vargas, 1995 by the presence of medially meeting costulae with a transcostula and notogaster divided by a longitudinal ridge and transverse ridges in several fields. However, it clearly differs by body size (344 – 387 × 190 – 228 vs. 213 – 258 × 110 – 132), shape of lamellar, interlamellar and notogastral setae (lamellar setiform, interlamellar and notogastral: phylliform vs all cymbiform), shape and size of the bothridial setae (long with flabellate head vs short with globose head) and ventral ornamentation of the integument (foveolate vs smooth). Eremella cochlearia is the longest species described so far, being 10 % longer than the next longer species (E. ryabinini) and 80 % longer than the smallest known species (E. reticulatus).	en	Tobar, Harol Revelo, Martínez, Pablo A., Palacios-Vargas, José G., Colina, Gabriel Otero- (2025): New species of oribatid mites (Acari, Oribatida) of the genera Ommatocepheus (Cepheusidae) and Eremella (Eremellidae) from Mexico.
