Mahunka, S.: Some oribatid mites from Yemen (Acari: Oribatida) (Acarologica Genavensia LXXXVIII)

Yemenobodes gen. n. Diagnosis - Family Carabodidae. Whole body surface and legs, excepting tarsus and tibia covered by peculiarly thick, unremovable, cerotegument layer. Prodorsum with a strong transversal elevation, notogaster with a protruding, rounded median part. Sensillus falciform, with thick, serrate, velum-like lateral part. Ten pairs of minute notogastral setae present. Epimeral setal formula: 3 - 1 3-3. Anogenital setal formula: 4-1-2-3. Gnathosoma and legs typical for the family, setae u on tarsi II-IV thickened, blunt at tip. Type species - Yemenobodes improvisus sp. n. Remarks - The single specimen was difficult to study, but it could not be placed in any of the heretofore known taxa (cf. MAHUNKA 1986). Other important feature: the position of setae Ci (near to shoulder) and the five setae (da - hi) on the median elevation of the notogaster. Etymology-The new genus is named after the country where the type species has been found. Yemenobodes improvisus sp. n. (Figs 7-9) Materied examined - Holotype: Yemen 543: MHNG. Description - Measurements: Length of body: 251 pm, width of body: 138 pm. Integument: The cerotegument layer is partly thin (e.g. on prodorsum or leg joints, partly consisting of small granules (e.g. on the coxisternal region) and the small granules also compose larger pustules, which cover the notogaster and the main part of the ventral plate. Prodorsum: Rostral apex and the lamellae typical for the family. A short, weak and simple tutorium also normal in size. Lamellar and rostral setae thin, simple, the preceding ones arising on the lamellar surface, latter ones (their alveoli) clearly in front of them. (Neither their shape nor their size could not been observed in detail). The elevated median part higher laterally and slightly lower medially, it appears as a well-sclerotised translamella. Basal part of prodorsum without any peculiar sculpture. Sensillus long, directed out- and downwards. Its shape well observable only in anterior or lateral (Fig. 9) aspect. It is likely that the asymmetrical, unilateral "velum" consists of very long, thick cilia, stuck together by the cerotegument layer. Notogaster: Dorsosejugal suture deep, its position hardly observable. Median protruding part well separated from the lateral "margin". Shoulder large, well protruding laterally. Ten pairs of minute, slightly dilated notogastral setae present hardly reaching over the cerotegument pustules (Fig. 7). One pair (c:) arising on the inner margin of the shoulders. On the elevated median part 5 pairs are present, further 4 pairs of setae are in posteromarginal position. Ventral regions (Fig. 8): Anterior third of mentum clearly foveolate. Apodemes and epimeral borders hardly visible. Epimeral setae minute or represented only by their alveoli. Genital plates also with some irregular foveolae, surface of anal plates smooth. Setae in the anogenital region also minute. Setae ad, and adi slightly thickened. Lyrifissures iad hardly observable.
