The genus Arrhopalites Börner, 1906 (Collembola, Appendiciphora, Arrhopalitidae) in the Neotropical Region, with description of four new cave species from Brazil Author Zeppelini, Douglas text Zootaxa 2006 1124 1 40 journal article 50757 10.5281/zenodo.171788 ef6107b2-b18b-42b2-ac42-60b992d8ae78 1175­5326 171788 Pararrhopalites wallacei n. comb. Syn.: Arrhopalites wallacei Palacios­Vargas & Zeppelini, 1995: 18 –20, figs. 41–48 Material examined: Holotype Ψ, 16­vi­1991 . BRAZIL , Sao Paulo, Iporanga. Morro Preto cave. Trajano leg., LESM . Body setae sparse, short and spinelike in the fore part of the body, as long as unguis and not spinelike at the hind part. Antennae of holotype more than twice as long as the cephalic diagonal. Ant. IV with eleven subsegments. Ant. III without basal swelling; sense organ with sense rods in a single pit; seta Aai club­shaped and acuminated, other setae normal. 1+1 eyes, pigments absent. Dorsal cephalic A2, A3, L2, and IL series spinelike. Metatrochanteral organ absent. All ungues without inner tooth and tunica. Unguiculi without corner tooth, apical filament in first and second unguiculi not exceeding unguis tip, absent in third. Dens 3,2,2,1,1 ventral setae. Mucro narrow, gutter­like one edge slightly serrated and other smooth. Anal valve without cuticular spines; anal valve without wingged or swollen setae, C6 lacking (Tab. II). Female subanal appendage acuminate pointing to anal opening. Biogeographic zone 27. Remarks: This species is similar to P. hennigii n. comb. and shares with it the subanal appendages pointing to anal opening, instead of pointing to genital pore, the metatrochanteral seta D2 not modfied into a sensory organ accommodated in an elongate, triangular socket, and the presence of a trochanteral spine. The dental E1 and L1 are not spinelike and the anal valve B2 and C6 absent. P. w a l l a c e i n. comb. differs from P. hennigii in the number of subsegments of the Ant. IV, number of eyes and chaetotaxy.
