Body with smooth and ciliated chaetae of different sizes, oval scales hyaline, trichobothria long and ciliated. Ratio head: antenna 1: 2.5, ratio antenna: body length 1: 1.9. Ant. I-II with scales. Ratio of Ant. I-IV as 1: 2.6; 2.5; 3.7. Apex of Ant. II with three candle-shaped sensilla, two close to each other and a third laterally displaced (Fig. 2). Apical sensory organ of Ant. III with two candle-shaped sensilla, apical guard chaetae thicker than others. Ant. IV undivided, with rows of chaetae and sensilla or finely ciliated microchaetae, without apical bulb. Eyes and pigment absent, head with two pairs of trichobothria (Fig. 3 A), chaetae Ps 5 and Pa 5 ciliated. Pre-labral and labral chaetae formula 4 / 5, 5,4; all chaetae smooth. Labial triangle with anterior row (A 1 - 5) smooth. All labial triangle chaetae smooth, labial seta R well developed, L 2 absent (Fig. 4). Legs with ciliated setae. Coxa of leg I with one chaeta. Metatrochanteral organ with 21 chaetae forming a " V " and 13 additional short chaetae (Fig. 5). Tenent hairs acuminate, shorter than ventral lamella of unguis (Fig. 6 - 8); ratio unguis: tenent hair = 1: 0.65. All unguis with two inner basal winged teeth of different sizes; one median inner tooth and one very small tooth at the base of the outer lamella. All unguiculi with well-developed outer lamella and normal sized inner lamella (Figs 6 - 8). Abd II with two trichobothria, Abd III-IV with three trichobothria each; Abd. IV with 4 + 4 lenticular organs on posterior margin (Fig. 9). Posterior surface of ventral tube with 2 long macrochaetae, scales on proximal end, 10 proximal pairs of ciliated chaetae and 11 distal pairs of small smooth chaetae; anterior face with only 2 pairs of ciliated macrochaeta (Fig. 10). Furcula with scales and ciliated chaetae; mucro, dens and manubrium ratio 1.0: 3.8; 4.2. The distal end of dens with a pair of large scales, about the same size of mucro (Fig. 11). Dens without spines, normal scales on anterior side, internal row of posterior face with 21 fringed scales (Fig. 12 A), median row with one fringed scale (Fig. 13 A). Other rows with finely ciliated chaetae in irregular pattern. Mucro elongated, bearing 10 - 15 teeth on outer lamella, inner lamella smooth with one tooth at the tip.	en	Zeppelini, Douglas, Silva, Diego Dias da, Palacios-Vargas, Jose G.

D5A482BBE923692D748F26B34A6D383B.taxon	etymology	Etymology. The name of the new species Troglobius ferroicus sp. n. comes from Latin ferrum (iron) and Greek oikos (house). This makes allusion to the iron caves where the new species was found.	en	Zeppelini, Douglas, Silva, Diego Dias da, Palacios-Vargas, Jose G.

EC45B7475B4FB2DEF57F17A222B7FD5B.taxon	diagnosis	Diagnosis. Habitus as Entomobryomorpha, eyeless, without pigment. Body with ciliated chaetae and hyaline ovoid scales. Mesothorax and metathorax not humped or bent. Ant. IV not subdivided. Labial chaetotaxy with chaetae: M 1, M 2, R, E and L 1 present, L 2 absent. Head bearing two pairs of trichobothria. Mucro elongate, four times as long, or more, than its greatest width, with many serrations along one or both dorsal lamellae. Dens without spines, anterior side covered with scales. A couple of large scale, about the same size as mucro, present on apex of anterior surface of dens. Posterior side of dens with, at least, three rows of chaetae and scales. Some (or most) scales, or thick chaetae, of internal row deeply fringed. In other rows only some distal chaetae modified. Unguis and unguiculus with winged teeth.	en	Zeppelini, Douglas, Silva, Diego Dias da, Palacios-Vargas, Jose G.
