Trichouropoda caudata sp. n. (Figs 6-11) Diagnosis - Dorsal and marginal setae long and spiniform. Caudal part of dorsal shield with a lot of long, wide setae. All setae on marginal part of ventral side plumose. Ventral setae short and setiform. Ornamentation of latero-caudal part of ventral shield rugose. Genital shield of female large, wide without ornamentation and with process. Description - Female. Length of idiosoma 850-880 urn, width 640-680 urn. Shape oval, posterior margin rounded. Dorsal side (Fig. 6): dorsal shield with several long, smooth and spiniform setae. Caudal part of dorsal shield with a lot of wide, smooth spiniform setae. Two pairs of smooth setiform setae behind basis of wide spiniform setae. Foveolate ornamentation on dorsal shield. Scalloping between marginal and dorsal shields. Ventral side (Fig. 7): sternal setae not clearly visible. Sternal shield without ornamentation. All setae on marginal part of ventral side plumose (Fig. 8). Ventral setae short and setiform. Ornamentation of latero-caudal part of ventral shield rugose, the ornamentation of other part of ventral shield lacking. Anal setae short and setiform similar to ventral setae. Peritrema not clearly visible. Genital shield situated between coxae 1 and anterior part of metapodal line, large, wide and scutiform, without ornamentation and with thick process. Gnathosoma (Fig. 9): corniculae horn-like with a strong spine, laciniae not clearly visible. Ventral side of gnathosoma with 4 pairs of coxal setae. CI long, smooth and setiform, C2 short, smooth and bifurcate, C3 short, smooth and trifurcate, central branch longer than other two, C4 short, serrated distally. Base of tritosternum narrow, without spines, lacininae serrated distally, with two short branches (Fig. 10). Epistoma long, distally serrated. Chelicera is shown in the Fig. 11. Male, deuteronymph, protonymph and larva unknown. Material examined - Holotype: female, "Mauritius, Black River National Park, Upland climax forest on ridges NNE of Black River Gorges, from moss, at 640 m a.s.l., 17.03.1995. leg. T. PÓCS". Paratypes: 2 females, locality and date same as holotype. Other material: one femlae, Mauritius, He au cerf (offshore island at the E coast), from moss, 19.03.1995. leg. T. PÓCS. Etymology - This species is named after its setate caudal part. Remarks - The caudal part of the new species is very characteristic; it is unlike any other Trichouropoda species.
