The specific name refers to Little Miss Spider, a very popular spider around the world and the main character of the children’s books by David Kirk.


Ochyrocera misspider   is the smallest among the species from Floresta Nacional de Carajás and resembles O. caeruleoamethystina   Lopez & Lopez and O. thibaudi   Emerit & Lopez by the small projection in the cymbium (see Lopez and Lopez 1997, fig. 8; Emerit and Lopez 1985, fig. 1A). It can be distinguished by the male palp with an elongated tibia, twice as long as the cymbium, and by the bifid embolus (Figs 13 C–D, 14 A–B). Females are distinguished from other species of the genus by the genitalia with a very long and narrow medial columnar uterus externus, internally with approximately 12 chambers, and an elongated, erect and sinuous spermathecae (Fig. 13 F–G).


Male (holotype). Total length 1.8. Carapace length 0.6, ovoid; narrowing gradually anteriorly; with purplish pattern pars cephalica flat; fovea not visible (Fig. 13A). Clypeus length 0.7, curved forward. Eyes: PME elongated oval; ALE and PLE rounded. Chelicerae light yellow; promargin with seven teeth, attached to long lamina (Fig. 16A), retromargin without teeth. Sternum light yellow. Endites white yellow suffused. Legs: light purple, formula 1423, total length: I 7.0; II 5.9; III 4.1; IV 6.5. Male palp: palpal femur length 0.4; palpal tibia twice as long as cymbium (Fig. 13 C–D); cymbial apophysis long and slightly curved with elongated cuspule at tip, two retrolateral long hairs on projected base, one tarsal organ and three basal setae (Figs 13C, 14B, E–F, 15A); cymbial prolateral extension rounded (Fig. 14A); bulb oval; embolus elongated, flattened at base and with distal area bifid, with short branch notched (Figs 14 A–B, 15 B–D). Abdomen length 1.3, oval; evenly purplish-green color (Fig. 13A). Six epiandrous spigots, with short base (Fig. 16C).

Female (paratype IBSP 176870). Total length 1.9; carapace length 0.74, as in male (Fig. 13B). Pedipalp without claw with conical tip, subdistal trichobothrium and tarsal organ (Figs 16 E–F). Clypeus 0.68 diameter. Eyes, chelicerae, sternum, endites (Fig. 16D) and labium as in male. Legs as in male, formula 4123, total length I 6.3; II 4.7; III 3.6 IV4.3. Abdomen length 0.96, globular (Fig. 13B). Colulus triangular, with 9 bristles (Fig. 16B). Internal genitalia with elongated and sinuous spermathecae; long medial columnar uterus externus, longer than spermathecae, with visible chambers. Narrow neck in the columnar uterus externus. Small oval pore-plates on the spermathecae base, with approximately 8-10 glandular ducts (Fig. 13 E–F).


Recorded exclusively from caves in the Carajás region, state of Pará, northern Brazil (Fig. 19B).
