Pararrhopalites papaveroi n.comb.

Syn.: Arrhopalites papaveroi Zeppelini & Palacios­Vargas, 1999: 78 –81, figs. 1–14.

Material examined: Holotype Ψ and 5 paratype ΨΨ, 03­vii­1998. BRAZIL, Mato Grosso do Sul, Bonito. Joao de Arruda cave. Zeppelini leg., MZUSP. 1 paratype Ψ, 19­VII­1991. BRAZIL, Mato Grosso do Sul, Bonito, Lago Azul cave. Zeppelini leg., MZUSP.

Fig. 3 , A–K. Body setae as shown in figure D. Antennae of holotype 1.8X as long as the cephalic diagonal. Ant. IV with ten subsegments (Fig. A), apex with a capitate sense rod (Fig. B). Ant. III without basal swelling; sense organ (Fig. C) with enlarged sense rods in separate pits; seta Aai, curved and blunt; Ape and Api long, slender and acuminate, a supplementary Ape is present; other setae normal. 0+0 eyes, pigments absent. Dorsal cephalic setae spinelike, chaetotaxy as figure J. Metatrochanteral organ absent, seta D2 normal, trochanteral spine present with a membranous wing (Fig. G). First unguis without inner tooth, no tunica. First and second unguiculi with apical filament exceeding unguis tip, all unguiculi with a small corner tooth (Figs. K, a–c). Corpus tenaculum with two setae (Fig. H). Dens 3,2,2,1,1 ventral setae, chaetotaxy as in figure E and table 3. Mucro narrow, gutter­like, one edge serrated and other almost smooth (Fig. F). Anal valve without cuticular spines; anal valve chaetotaxy as in figure I and table 2. Female subanal appendage acuminate, pointing to anal opening.

Biogeographic zone 27.

Remarks: This species is the fourth of the group and shares with P. hennigii n. comb., P. w a l l a c e i n. comb., and P. christianseni n. comb. the same distinctive features. P. papaveroi n. comb. can be easely differentiated from other species in its group by the absence of eyes, the number of subsegments in Ant. IV and by the apical sensory organ of Ant. III.
