Type locality

Brasil, Rio de Janeiro, Teresópolis municipality, Parque Nacional da Serra dos Órgãos (ICMBio), 22°27'38"S, 43°1'45"W, leaf litter and soil of “campos de altitude”, 2,100 m a.s.l.

Description

Habitus typical of the genus. Body length of holotype: 0.62 mm; body length range of paratypes: 0.40–0.75 mm. Color in ethanol: white, no pigmentation.
Ratio head diagonal: antenna = 1:0,.66. Ant I with 7 chaetae. Ant II with 11 chaetae. Ant III and IV fused dorsally, ventral separation marked. Sensory organ of Ant III with two cloverleaf-shaped sensilla partially covered by a fold of the integument; two longer and subcylindrical guard sensilla, the dorsal one is shorter but greatly enlarged in its width, in relation to the ventral one; ventral microsensillum present (Figs 15–18). Ant IV with simple apical bulb and four sensilla; dorsolateral microsensillum present; subapical organite round; with about 30 ventral chaetae (Fig. 16). Without eyes. PAO bearing 12–13 vesicles disposed as a rosette. Maxillae quadrangular with 6–7 teeth (Fig. 19). Labral formula: 2/2334. Labium typical of Brachystomella, with one papillated chaeta (L) and four proximal chaetae (Fig. 20).
Head chaetotaxy as in Fig. 21. Chaetae a0 present; Oc chaetae 3+3, sometimes asymmetric of 2+3. Dorsal chaetotaxy composed of smooth ordinary chaetae (10–25μm) and long sensilla (25–50μm), that becomes longer towards distal segments of the body. Ratio body ordinary chaetae: sensilla = 1:2. Th I with 2+2 chaetae; sensillar formula by half tergum: 022/211110 (Fig. 22).
Chaetotaxy of legs I–III as follows: Scx I– 1, 2, 2; Scx II– 0, 2, 2; Cx– 3, 6, 7; Tr– 5, 5, 4; Fe– 12, 11, 10; Tita– 19, 19, 18. Tenent hair on tibiotarsi acuminate; unguis without tooth (Fig. 23). Ventral tube with 3+3 chaetae. Without tenaculum. Furca completely absent, but with a well-defined furcal area with six chaetae (Figs 24–25).Each anal valve with 11–12 chaetae and 2 hr chaetae; Abd VI with 3+3 chaetae on ventral side, 4+4 chaetae on dorsal side and one unpaired chaetae (Figs 26–27). Female genital plate as in Fig. 28.

Etymology

In a reference to the size of the sensilla in relation to ordinary chaetae on body of the new species.

Discussion

The new species, Micronella longisensilla sp. n., is well characterized in the genus (see Table 1). It differs from its congeners in relation to the ratio of ordinary chaetae: sensilla, that is 1:2, only four sensilla on Ant IV, a PAO with 12–13 vesicles, the Ant III organ with two cloverleaf-shaped sensilla under a fold of the tegument and the dorsal guard sensilla which is greatly enlarged in its width, in relation to the ventral one.
