03D7878AFF822019FF3ABC00FB7BFE5E.taxon	etymology	Etymology. The specific name “ hypergranulosa ” refers to heavy integumentary granulation present on the whole body.	en	Palacios-Vargas, José G., Villagomez, Fernando (2017): Three new species of Pergalumna (Acari: Oribatida: Galumnidae) from the tropical rainforest of Veracruz, Mexico.

03D7878AFF822019FF3ABC00FB7BFE5E.taxon	discussion	Remarks. Due to cerotegumentary granulation, P. hypergranulosa sp. nov. resembles Pergalumna granulatus Balogh & Mahunka, 1967 (Vietnam), from which it differs by only unilaterally barbed bothridial setae and a more heaver granulation. Pergalumna elongatiporosa Ermilov et al. 2014 (Costa Rica), has elongated and folded porose areas A 1, giving a horseshoe aspect, while in this new species they are straight. It is also similar to Pergalumna paralongisetosa Ermilov & Kalúz, 2012 (from Ecuador), which shows a granulated cerotegument only on the prodorsum, while the notogaster is smooth; also bothridial setae (bs) are shorter than interlamellar setae (in), adanal setae are extremely long, and there is also a considerable difference in the size of the body (L = 1062 – 1261, W = 713 – 863 vs. L = 470 – 490, W = 350 – 390). Finally, Pergalumna silvatica Hammer, 1961 (Peru) also shows a granulated anterior region of the prodorsum, but interlamellar setae in are minute, and there are four pairs of round notogastric porose areas while P. hypergranulosa sp. nov. has only three pairs and all are elongated.	en	Palacios-Vargas, José G., Villagomez, Fernando (2017): Three new species of Pergalumna (Acari: Oribatida: Galumnidae) from the tropical rainforest of Veracruz, Mexico.

03D7878AFF872016FF3AB8A0FCE3FCA9.taxon	discussion	Remarks. Pergalumna obsidiana sp. nov. has a strong resemblance to P. hypergranulosa sp. nov. by integumentary granulation, shape and position of porose areas and bothridial setae bs, however it may be easily differentiated by the shape and ornamentation of genital plates, interlamellar setae (in) inserted in L margin, presence of a rostral sclerotic extension, subcapitulum with anterior apex bilobed and more intense and shiny dark coloration. Furthermore, it differs from P. granulatus by barbulate bs in only one side and protuberances in genital plates, from P. elongatiporosa by the shape of A 1, from P. paralongisetosa by having heavier granulation on the notogaster and from P. silvatica by four notogastric porose areas.	en	Palacios-Vargas, José G., Villagomez, Fernando (2017): Three new species of Pergalumna (Acari: Oribatida: Galumnidae) from the tropical rainforest of Veracruz, Mexico.

The specific name “ dactylaris ” describes the similarity of the integumentary ornamentation with human fingerprints.	en	Palacios-Vargas, José G., Villagomez, Fernando (2017): Three new species of Pergalumna (Acari: Oribatida: Galumnidae) from the tropical rainforest of Veracruz, Mexico.

03D7878AFF882013FF3ABDF7FCB2FD7E.taxon	discussion	Remarks. The ornamentation on the prodorsum and notogaster of P. dactylaris sp. nov. resembles Pergalumna striata (Pérez-Íñigo & Baggio, 1980), from Brazil, but can be distinguished by the presence of only three notogastric porosea areas instead of four, and being almost twice as long as in P. striata (400 – 440). The shape of bothridial setae bs is similar to Pergalumna decorata Balogh & Mahunka, 1977 (Bolivia), which has Aa closer to lm than la, whereas in P. dactylaris sp. nov. Aa is located exactly in the middle between them; besides interlamellar setae in are short, but not minute, and the Bolivian species is much smaller (L = 637 – 653, W = 469 – 494) than the Mexican (L = 838 – 986, W = 720 – 789). New species is also similar to Pergalumna decoratissima Pérez-Íñigo & Baggio, 1986 (Ecuador) which has a granulated prodorsum and the rest of the body ornamented with longitudinal striae or grooves, however, lamellar setae (le) in this species is more than twice as long as rostral setae (ro), and the anal and genital plates are ornamented in the same manner, while in P. dactylaris sp. nov. prodorsal setae le and ro are subequal in size, also genital and anal plates are ornamented with different patterns, with less ornamentations on genital plate. Finally Pergalumna paradecoratissima Ermilov & Kalúz, 2012 (Ecuador) differs by having a tooth-shaped projection on each side of prodorsum, anal plate smooth and the presence of one small and oval porose area postanalis. In addition, P. dactylaris sp. nov. seems to be the only species with a clear and well delimitated lenticular region between prodorsum and the base of notogaster. Sympatric speciation. The three species come from Los Tuxtlas, Veracruz, and as they live in the same locality and biotope, it seems that a sympatric speciation has occurred. We have analyzed the chelicerae, but we have not found any important difference, but we think that each of them is using a new niche, which had reduced gene flow with individuals exploiting another niche. Unpublished data support this, Villagomez (2015) performed techniques of extraction and amplification of ribosomal 18 S rRNA and mitochondrial Cytochrome Oxidase c 1 (Cox 1) for molecular characterization of these species and to delimit the relationship between genetic distance and morphological characters. The results show that genetic distance between species with molecular marker Cox 1 observed in the three species varies from 0.3, 2.46 or 6.02 %.	en	Palacios-Vargas, José G., Villagomez, Fernando (2017): Three new species of Pergalumna (Acari: Oribatida: Galumnidae) from the tropical rainforest of Veracruz, Mexico.
