Leonardiella machadoi sp. n.

( Figs 8–13 View Figs 8–13 )

Diagnosis: Characteristic idiosoma with several strong setiform setae on marginal shield and on central and caudal part of dorsal shield. Ventral and dorsal side without ornamentation. Marginal part of dorsal shield with a wide and wellsclerotised line. Genital shield of females without ornamentation and scutiform.

Description: Female. Length of idiosoma 910 µm, width (in the middle of idiosoma) 630 µm (n = 1). Shape characteristic, posterior margin rounded, anterior margin with vertex.

Dorsal side ( Fig. 8 View Figs 8–13 ): Dorsal shield with two types of setae. Central and caudal part with strong, smooth and spiniform setae, while anteromarginal part with T-shaped setae. Ornamentation of dorsal and marginal shields lacking, marginal setae similar to dorsal ones.

Ventral side ( Fig. 9 View Figs 8–13 ): Ventral shield without ornamentation. All ventral setae not clearly visible. Several short T-shaped setae on caudal part of ventral shield. Marginal setae short, thin and spiniform. Sternal setae not clearly visible. One pair of spiniform setae under coxae 4 near metapodal lines. Genital shield between anterior margin of sternal shield and coxae 4, large, scutiform and without ornamentation.

Gnathosoma ( Fig. 10 View Figs 8–13 ): Corniculi short, horn-like, laciniae with four thicker branches and bearing many thinner branches.Gnathosomal setae are the following: h1 and h3 short, smooth and setiform, h2 long, smooth and setiform, h4 long, apically serrated. Tritosternum with four branches, carrying many thinner branches ( Fig. 11 View Figs 8–13 ). Base of epistome not clearly visible, anterior part with long hairs ( Fig. 12 View Figs 8–13 ). Chelicerae not clearly visible, apical part as shown in Fig. 13 View Figs 8–13 .

Male, deuteronymph, protonymph and larva unknown.

Material examined: holotype: female, Angola, Dundo , foret R . Casulo May 1980, leg. SZABÓ .

Etymology: The species is dedicated Dr. A. DE BARROS MACHADO, who collected various materials in Angola.

Remarks: The most important differentiating characters of the new species are the strong setiform setae in dorsum and the characteristic shape of the idiosoma.
