Locality — Malagasy Republic, Antananarivo Prov. Angavo Escarpment. Old Eucalyptus plantation replacing montane rainforest at the S side of main road between Ambatolaona and Mandraka 40 km E from the capital, at 1350-1400 m alt. 18'54.3-9'S, 47'53.6-7'E. Date: 27. August 1998. Leg. T. Pocs. No. 9891. Oribotritia paraspinosa sp. n. (Figs 1-5) Description — Measurements: Length of aspis: 297-320 pm, length of notogaster: 555-596 pm, height of notogaster: 426-440 pm. Aspis: Outline of the prodorsum gradually convex in lateral view (Fig. 4). Two pairs of very strong lateral carinae present, running anteriorly, slightly diverging and in the rostral region touching the well developed lateral rim. Bothridial squama large, straight at its free margin, situated above the bothridium. Prodorsal cuticle punctate. Three pairs of prodorsal setae, setae exa reduced, their alveoli absent. Rostral and interlamellar setae erect, thicker than setae le, which is fine, thin and much longer than the remaining ones, and addpressed to the surface. Sensillus distinctly dilated distally, with well observable velum. Notogaster (Fig. 1): Fourteen pairs of notogastral setae present. All - excepting setae c

3 andps

2-curved, aciculate, the latter two setae simple, setiform and fine. Four pairs of lyrifissures well observable. Anogenital region (Fig. 2): Median cleft trv large. Nine pairs of genital, two pairs of aggenital, one pair (setae a

x

) and three pairs of adanal setae present. Legs: Legs tridactylous, median claw much thicker than the lateral ones. Legs setal formulae are typical for the genus. Setae d of femur I (Fig. 5) reaching over the distal end of the femoral spur. Setae u " of tarsus IV dilated, curved, spiniform. Material examined — Hototype: Malagasy Republic, Antananarivo Prov. Angavo Escarpment. Old Eucalyptus plantation replacing montane rainforest at the S side of main road between Ambatolaona and Mandraka 40 km E from the capital, at 1350-1400 m alt. 18-54.3-9'S, 47'53.6-7'E. Date: 27. August 1998. Leg. T. Pócs. No. 9891, 4 paratypes from the same sample. Holotype (1636-HO-99) and 2 paratypes (1636-PO-99) deposited in the Hungarian Natural History Museum (HNHM), Budapest, with identification number of the specimens in the Collection of Arachnida, 1 paratype: in the Muséum d'Histoire naturelle, Genève (MHNG), 1 paratypes: in the collection of Dr. W. Niedbala. Remarks — The new species is closely related to Oribotritia spinosa (Mahunka, 1988). The new species is well distinguishing from it by the presence of two lateral carinae (one in spinosa), by the slightly dilated sensillus (thin, setiform in spinosa), the form of the bothridial squama and the presence of the setae a, (absent in spinosa). The occurrence of O. spinosa in Madagascar has been reported from several localities by Niedbala. The species was redescribed and the genus of Philotritia Mahunka, 1988 was synonymized. Owing to this new material and new species I examined the type specimens of deposited that they are identical with the original description, and the redescription of Niedbala. Furthermore, Niedbala was right in stating that the lateral carina is a single broad carina whose basal part (lower margin) is rather weakly developed. Niedbala also makes mention of specimens which bear on their anal plate one pair of anal setae. The other features separating the two species, as mentioned herewith [sensillus, shape of bothridial squama (Fig. 6), femur I (Fig.7)], however, he did not make reference to. Consequently, those specimens may also belong to this species.
