Baloghoizetes pluritrichosus sp. n.

( Figs 1–4 )

Diagnosis. Lamellae large, reaching over the rostral part, connected by a thin translamella. Rostrum very wide, with slightly protruding rostral apex and two longer horn-shaped formations. Interlamellar setae short, arising on the median border of the lamellae. Sensillus unilaterally spinose. Two transverse apodemes present: ap. sej. and ap. 4, sternal apodeme absent. Epimeral setal formula 4(5)–3–3–3. Anogenital setal formula typical for the genus.

Measurements – Length of body: 335 (with lamellae 383) µm, width of body: 238 µm.

Prodorsum: Lamellae very large, covering the whole prodorsum, excepting a smaller basal, a median, and the rostral part ( Fig. 1 ); they touch medially and are connected by a narrow translamellar band. Cusps are wide, approaching each other. Lamellar surface rugose laterally, dentate distally ( Fig. 4 ). Anterior part of prodorsum very wide, its median apex low, triangular, well visible in a hollow composed by lamellar cusps. Rostral setae bulbiform basally, with long cilia, their distal part long, filiform. Lamellar setae arising on the bottom surface of the lamellae, spiniform, not reaching the lamellar apex. Interlamellar setae very short, fine, arising on the inner margin of the basal part of the lamellae. Bothridium normal, cup-shaped; sensillus long, setiform, directed laterally and posteriorly, its distal end strongly curved and its margin unilaterally spinose, the spines dense basally, rarer distally.

Notogaster: Dorsosejugal part normal, without any indentation. Pteromorphae small, triangular, with short lateral spur. Their surface well rugose. Nine pairs of short, fine but well observable notogastral setae present.

Lateral view of podorsum: Rostral apex beak-shaped in lateral view. Lamellae widening anteriorly. Tutorium very large, with spiniform triangular anterior apex and a large, also sharply pointed median part ( Fig. 4 ). Pedotectum I very large, its surface well rugose. Circumpedal carina not reaching the lateral margin of the ventral plate.

Ventral parts ( Fig. 2 ): Apodemes, except the sternal one, well observable, both pairs (ap. sej. and ap. IV) compose transverse bands. Epimeral surface without distinguishable pattern. Epimeral neotrichous setal formula: 4(5)–3–3–3 ( Fig. 3 ). Setae on the 1st and 2nd epimeres are shorter than the same on the posterior ones. All setae finely pilose. Anogenital setal formula: 6–1–2–3. Anterior setae on the genital plates only slightly longer than the others. Aggenital, anal and adanal setae short, simple.

Legs: All legs monodactylous.

Material examined: Holotype: Kenya, Shimba Hills National Park , near the Lodge. 10 March, 2001. From litter and soil of montane rainforest. Leg. S. MAHUNKA and L. MAHUNKA- PAPP. Holotype (1662-HO-02) deposited in Soil Zoological Collection of the Hungarian Natural History Museum, Budapest .

Remarks: See the remarks after the generic diagnosis.

Derivatio nominis: The new species is named after the epimeral neotrichy.
