Etymology.

The name is an adjective referring to the pale coloration of the body in both males and females of this species.

Diagnosis.

Misionella pallida can be distinguished from other Misionella species by the pale coloration of the body. Males are further distinguished by the large and flattened paraembolic lamina (Figs 5 G–H, 6 A–E: PL, 11 G–H). Females can be recognized by the long, distally incrassate, and largely separated distal area of the spermathecae (Fig. 11I).

Description.

Male (MPEG 22756). Carapace orange with thoracic groove, lateral stripes and border black. Ocular area black. Chelicerae and labium orange. Endites and sternum cream. Legs and palps orange. Abdomen dorsally greyish, with grey stripes in the anterior border, and ventrally cream (Fig. 5A). Total length 3.0. Carapace 1.3 long, 1.0 wide. Sternum with small and shallow sulcus, without sigillae. Eye diameters: PME 0.4, separated by about four diameters. Pedipalp: femur length 0.9, patella 0.3, tibia 0.5 long, 0.3 wide. Leg measurements: I: femur 2.5, patella 1.0, tibia 3.0, metatarsus 2.3, tarsus 1.1, total 9.9; II: 1.8, 0.5, 2.0, 1.2, 0.5, 6.0; III: 1.3, 0.4, 1.0, 1.1, 0.4, 4.2; IV: 1.9, 1.0, 2.0, 1.7, 0.6, 7.2. Metatarsus II with a pair of hirsute macrosetae (Figs 5 D–F, 7 A–D). Abdomen 1.7 long, epiandrous area with at least 15 fusules (Fig. 9A). Cribellum divided and smooth (Fig. 9B). Spinnerets: ALS with one major ampullate gland spigot and at least 20 piriform gland spigots, PMS with one minor ampullate gland spigot, two aciniform gland spigots and one elongated paracribellar gland spigot, PLS with one paracribellar gland spigot and two aciniform gland spigots (Fig. 9B, D–F). Palp: tibia elongated, short cimbyum, bulb globose, with large and flattened paraembolic lamina (Figs 5 G–H, 6 A–E, 7 A–E, 11 G–H).

Female (MPEG 22748). Coloration as in male, except pedipalp red brown and abdomen greenish gray with anterior dorsal border black (Fig. 5 B–C). Total length 4.0. Carapace 1.7 long, 1.2 wide. Sternum as in male. Eye diameters: PME 0.4, separated by about 2 diameters. Pedipalp: femur length 1.1, patella 0.5, tibia 0.7, tarsus 0.3. Leg measurements: I: femur 1.8, patella 0.5, tibia 2.1, metatarsus 1.4, tarsus 1.0, total 6.8; II: 1.4, 0.5, 1.2, 1.0, 0.6, 4.7; III: 1.2, 0.4, 0.9, 1.0, 0.5, 4.0; IV: 1.7, 0.5, 1.5, 1.3, 0.6, 5.6. Abdomen 2.4 long. Cribellum as in male, but more numerous spigots (Fig. 10 B–C). Spinnerets: ALS as in male, PMS with one minor ampullate gland spigot, at least one aciniform gland spigots and one elongated paracribellar gland spigot, PLS with one paracribellar gland spigot and four aciniform gland spigots (Fig. 10A, D–F). Spermathecae curved at tip with elongated ducts (Figs 8 A–D, 11I).

Variation.

10♂: total length 1.9‒2.8; carapace 1‒1.3; femur I 1.4‒2.6; 10♀: total length 3.8‒4.2; carapace 1.6‒1.8; femur I 1.8‒2.1.

Natural history.

This species has been collected several times in both natural and synanthropic habitats in northeastern Brazil. The species seems to naturally occur in Caatinga vegetation, a type of seasonally dry tropical forest. In synanthropic conditions, females can be found in their webs in the corners and cracks of windows and doors (L.S. Carvalho, pers. comm.). Males have been collected in pitfall traps in Caxias, in the state of Maranhão.
