( Figs 38–40 View Figs 38–40 )

Diagnosis: Dorsal and marginal shield with several long, smooth and setiform setae. Ventral setae strong, long and spiniform. Three pairs of ventral setae on the postcoxal region near to metapodal lines. Peritreme U-shaped. Genital shield of female linguliform with alveolar ornamentation.

Description: Female. Length of idiosoma 390 µm, width (in the middle of idiosoma) 330 µm (n = 1). Shape oval, posterior margin rounded.

Male, deuteronymph, protonymph and larva unknown.

Dorsal side ( Fig. 38 View Figs 38–40 ): Dorsal and marginal shield fused, without pattern, all dorsal and marginal setae long, smooth and setiform.

Ventral side ( Fig. 39 View Figs 38–40 ): Ornamentation of sternal shield lacking. Sternal setae short, strong, smooth and setiform. Ventral setae long, strong, smooth and spiniform. Three pairs of ventral setae on the postcoxal region near to metapodal lines. Ventral shield without alveolar ornamentation. Peritreme U-shaped.

Genital shield of female linguliform and with alveolar ornamentation. The anterior part of the genital shield situated between coxae 2.

Gnathosoma ( Fig. 40 View Figs 38–40 ): Corniculi horn-like, laciniae long, apical part plumose. Ventral side of gnathosoma with 4 pairs of coxal setae. h1 long, smooth and setiform, h2, h3 and h4 short, smooth and setiform, with three strong branches, central branch longer than the other two.

Material examined: holotype: female, Angola, Lovula, foret R. Camamga May 1980. leg   .


Etymology: This species is dedicated to Dr. SÁNDOR MAHUNKA, head of the Systematic Zoology Research Group of the HAS, who helped the author extensively with the work and study of acarology.

Remarks: The new species is similar to Rotundabaloghia   humicola HIRSCH- MANN, 1992, but sternal setae of the new species are short, while Rotundabaloghia   humicola has long sternal setae.
