Bioacoustics of Anelosimus dude

Description Male ( holotype ): Total length 1.85. Prosoma 0.90 long, 0.70 wide, brown, cephalic area and a narrow rim around the edge slightly darker. Sternum 0.55 long, 0.45 wide, light brown with a narrow darker rim. Opisthosoma 1.00 long, 0.90 wide, with Anelosimus pattern, dull gray with a dorsal longitudinal notched fovea, bordered by bands of white. Colular setae are smaller than in most other Anelosimus and may be difficult to see under a dissecting microscope. Eyes subequal about 0.07 diameter. Clypeus height about 2.4 times AME diameter. Leg I femur 1.30, patella 0.25, tibia 0.95, metatarsus 0.70, tarsus 0.45. Legs pale yellow with distal half of femur I slightly darker. Femur I about 5 times longer than wide. 2–5 trichobothria dorsally on all tibia, 2–4 on tibia I–III, 4–5 on tibia IV. 2 prolateral and 1 retrolateral trichobothria on palpal tibia. Stridulatory pick row on opisthosoma nearly straight, consisting of approximately seven to eight modified setal bases ( Fig. 9E ). Epiandrous gland spigots in two clearly separate groups of 6–7 fusules ( Fig. 9B ). Palpal organ as in Figures 5D , 8A–F . Female ( paratype ): Total length 2.10. Prosoma 0.95 long, 0.70 wide, brown, cephalic area and a narrow rim slightly darker. Sternum 0.60 long, 0.50 wide, brown, slightly darker than male, with a narrow darker rim. Opisthosoma 1.25 long, 1.10 wide, pattern as in male. Colular setae are smaller than in most other Anelosimus and may be difficult to see under a dissecting microscope. Eyes subequal about 0.07 diameter. Clypeus height about 2.3 times AME diameter. Leg I femur 1.15, patella 0.30, tibia 0.95, metatarsus 0.85, tarsus 0.50. Legs brownish yellow with distal half of femur I darker and distal tip of femur IV and tibia I and IV also slightly darker. 2–5 trichobothria dorsally on all tibia, 2–4 on tibia I–III, 4–5 on tibia IV. 2 prolateral and 1 retrolateral trichobothria on palpal tibia. Epigynum as in Figures 5E–F , 9A . Va r i a t i o n Variation in coloration (in alcohol) of opisthosoma of both sexes is large and ranges from grayish with a dull folium to dark gray with a folium bordered with sharp white. The light gray coloration is more common. Leg coloration ranges from yellow to brownish. Male total length from 1.80–2.10, femur I from 1.15–1.40, female total length from 1.85–2.15, femur I from 0.95–1.20.
