Mahunka, S.; Mejia-Recamier, B. E.: Two new protoplophorid oribatids from Mexico (Acari: Oribatida)

Notogaster (Fig. 1): On the surface some weak polygonal areolae visible, the pygidial part distinctly punctate. Setae c and p simple, fine and smooth, setae e,fand h much stronger and longer, but without median thickening, true setiform. Their surface slightly roughened. Ventral regions: Epimeral setal formula: 3-2-3-3 (Fig. 4). Genital plates with the large posterior tectum, covering the ano-adanal plates. Their anterior part elongated, narrowing, well sclerotised. Nine pairs of genital setae present, all simple, thin, their length gradually become longer posteriorly. Anoadanal plates brick shaped, on their surface some foveolae also visible. The characteristic pouches are shallow. The position of the ano-adanal setae as shown in Fig. 3. Legs: Legs tridactylous, median claws thicker than the lateral ones, but all claws gradually getting longer from leg I to leg IV. All solenidia , first of all CÛ J conspicuously long, reaching to the distal end of the tarsus. Both solenidia on tarsus II also very long. Material examined: Holotype: Mexico, Chamela, forest near the seashore, collected 24th, X. 1995. Berlese sample from litter and soil in a dry forest "bosque espinoso seco" with Xanthoxylon and Pachycereus trees. 6 paratypes found from the same sample. Leg. Mahunka S. and A. Borhidi. No. 317. Holotype (1599-HO-98) and 3 paratypes (1599-PO98) (with identification numbers of the specimens in the Collection of Arachnida) deposited in the Hungarian Natural History Museum, Budapest, 2 paratypes in the Laboratorio de Ecologia y Sistemática de Microartrópodos, Depto. Biológia, Fac. Ciencias, UNAM, Mexico and 1 paratype in the Muséum d'Histoire naturelle, Genève. Remarks: The species of the Bursoplophora Subias & Pérez-Inigo, 1978 genus can be easily divided into species groups on the basis of the of the following distinctive characters: whether the body surface is smooth or strongly punctate, and by the numbers of the anal setae. The type species, (B. iberica Subias & Pérez-Inigo, 1978) is not punctate, and has 6 pairs of ano-adanal setae. Among the species known till today only B. meridionalis Bernini, 1983 has less then 6 pairs of ano-adanal setae (4), and its body surface is smooth. B. tyrrhenica Bernini, 1983, is also smooth, but similarly to the type species it also has 6 pairs of setae. B. bivaginata Grandjean, 1932 is punctate, and possesses 6 pairs of anoadanal setae, similarly B. ethiopica Mahunka, 1982 is punctate, possesses 6 pairs of anoadanal setae, B. insularis Kahwash, Subias & Ruiz, 1989 is punctate, possesses 6 pairs of ano-adanal setae, B. madegassica Mahunka, 1994 is punctate and possesses 6 pairs of anoadanal setae. The new species is strongly punctate and possesses 4 pairs of ano-adanal setae, and hence represents a new, unknown type. Based on these characters this species is markedly different from the formerly known species. It is also clear, that these features are not applicable for the separation of supraspecific taxa. Etymology: We dedicate the new species to Dr. Eva Murai-Kovács, the outstanding parasitologist of the Hungarian Natural History Museum, who founded and edited several scientific periodicals. We would like to commemorate her 70th birthday. Prototritia palaciosi sp. n. Measurements: Length of aspis: 165-176 pm, width of aspis: 130-138 pm, length of notogaster: 265-280 m, height of notogaster: 170-195 pm. Aspis: A small, rounded rostral apex observable, slightly flattened in lateral view, rounded in dorsal view. Lateral carinae well discernible, but not reaching to the small bothridia. Notogastral setae conspicuously thick, well ciliated. Rostral setae with extraordinary long
