Description.
Male. Habitus as shown in Figs 3 A – C View Figure 3 , 4 A – G, L View Figure 4 , 5 A, B View Figure 5 , 6 C, D View Figure 6 , 7 F View Figure 7 ). Measurements ( MHBU - ARA- 00025193): carapace 3.27 long, 2.65 wide, abdomen 4.19 long, 2.39 wide; measurements of eyes: AME 0.55, ALE 0.31, PME 0.09, PLE 0.34; measurements of legs: I 10.52 (3.42, 1.30, 2.91, 1.80, 1.09), II 6.92 (2.20, 0.97, 1.67, 1.19, 0.89), III 7.54 (2.18, 0.90, 1.60, 1.72, 1.14), IV 10.07 (3.07, 1.03, 2.36, 2.47, 1.14); leg formula 1432. Body black and pale yellow except for blue carapace edge, covered with dense scales (Figs 3 A – C View Figure 3 , 4 A – G, L View Figure 4 , 5 A, B View Figure 5 , 6 C, D View Figure 6 , 7 F View Figure 7 ). Chelicerae claybank color, with sparse blue scales (alive) and relatively dense setae on front surface, with two promarginal and one retromarginal tooth (Figs 5 M, P – R View Figure 5 , 6 F View Figure 6 , 7 E View Figure 7 ). Femur I covered with short setae (Figs 4 B, E, F View Figure 4 , 5 O View Figure 5 ). Number of teeth in each tarsal claw varied (Fig. 5 E – L View Figure 5 ).
Palp (Figs 8 A – F View Figure 8 , 10 A, B View Figure 10 , 11 E View Figure 11 , 12 C – E View Figure 12 ): embolus short; cymbium yellow, longer than wide; retrolateral tibia apophysis around one-third of bulb length; palpal bulb like wax apple, with tegular bump at lower right corner.
Female. Habitus as shown in Figs 1 A View Figure 1 , 4 H – K View Figure 4 , 5 C, D View Figure 5 , 6 A, B View Figure 6 , 7 B, D View Figure 7 . Measurements ( MHBU - ARA- 00025194): carapace 3.45 long, 2.81 wide; abdomen 4.70 long, 3.04 wide; measurements of eyes: AME 0.58, ALE 0.35, PME 0.10, PLE 0.30; measurements of legs: I 8.11 (2.54, 0.96, 2.15, 1.47, 0.99), II 6.72 (2.18, 0.84, 1.62, 1.20, 0.88), III 7.71 (2.27, 0.94, 1.67, 1.87, 0.96), IV 10.5 (3.15, 0.91, 2.52, 2.87, 1.05); leg formula 4132. Body form and color pattern same as male, but without short setae on femur I. Chelicerae lacking blue scales, with slightly different shapes of teeth from males (Figs 1 C, D View Figure 1 , 4 H View Figure 4 , 5 S – U View Figure 5 , 6 E View Figure 6 , 7 A, C View Figure 7 ).
Epigyne (Figs 1 E, F View Figure 1 , 9 A – G View Figure 9 , 10 C, D View Figure 10 , 11 A – D View Figure 11 , 12 A, B View Figure 12 ): copulatory openings elongate like curved butterfly antennae; copulatory ducts short; fertilization ducts at anterior of spermathecae; accessory glands small, located close to the junction between spermathecae and copulatory ducts.
Variation.
The transition from the base of the embolus to the tegulum is smoother in some specimens (Figs 8 B View Figure 8 , 11 E View Figure 11 ), but has an obvious junction in others (Figs 8 C View Figure 8 , 10 A View Figure 10 ). For the females, differences in the size of accessory glands, the shape of spermathecae, copulatory openings and middle rim of epigyne are observed among different individuals (Figs 1 E, F View Figure 1 , 9 A – E View Figure 9 , 10 C, D View Figure 10 , 11 A – D View Figure 11 , 12 A, B View Figure 12 ).
Natural history.
Specimens were discovered on the surface of leaf litter or in shrubs within tropical forests (Fig. 2 A – D View Figure 2 ), moving actively and quickly. These specimens were collected during relatively dry seasons, and the subsequent lab observations showed that they may not prefer highly humid environments. While the original description of O. mutilla suggested that the species mimics Mutilla Linnaeus, 1758 , a genus of parasitoid wasps ( Peckham and Peckham 1907), our field observations indicated that O. mutilla possibly mimics large sympatric ants, similar to the imperfect ant-mimicry phenomenon reported in some species of Siler ( Zeng et al. 2023) .
