Labial palp with segment I 0.8 × length of segments II and III combined; segment II dorsally with oblique row of 6–7 setae; segment III with distal margin slightly truncate; inner margin subequal to outer margin; ventrally covered with around 30 apically pointed setae; setae on inner margin serrate.

Fore leg ( Fig. 9 View FIGURE 9 d). Ratio 1.8:1(0.6mm):1.2:0.3. Femur. Length about 4 × maximum width; outer margin with row of 14 clavate setae (length of setae about 0.1 × maximum width of femur) ( Fig. 9 View FIGURE 9 e); submarginal setae absent; anterior surface and inner margin with around 35 simple, spine-like tiny setae; posterior surface with around 40 scattered setae near inner margin; distal projection exceeding apex of femur ( Fig. 9 View FIGURE 9 a), 0.2 × width of femur, apically with 2 clavate setae ( Fig. 9 View FIGURE 9 a). Tibia. Outer margin with many simple setae; inner margin with two serrate setae on apex; subtending bristle blunt, clavate, extending apex of tibia ( Fig. 9 View FIGURE 9 f).

Female imago. Unknown.

Etymology. From the tupi language words amana (rain) and tykyra (drop). An allusion to the type-locality of the new species, Serra da Mantiqueira, whose name is also derived from these two words.

Distribution ( Fig. 30 View FIGURE 30 ). Southeastern Brazil, São Paulo State, Serra da Mantiqueira, Parque Estadual de Campos do Jordão.

Ontogenetic stage association. Rearing.
