insecto de color negro con franja blanca, con cuatro pares de patas largas y un cuerpo ovalado
En pared del edificio VI de la Zona Arqueológica Oxtankah. Eran visibles varias telas de L. yucatana y otras que probablemente pertenezcan a una Filistatidae de buen tamaño
Se encontraron dos ejemplares juntos, en una recámara, mientras se realizaba la limpieza.
Especie sin importancia médica.
Macho subadulto saliendo por la noche a cazar alrededor de su árbol a unos 3m de altura.
Una de las pocas especies del género que habita dentro de cuevas y tiene adaptaciones troglomórficas.
Solifugid Sun Spiders mating. The male puts the female into a trance by massaging her with his pedipalps, then flips over her abdomen to insert a spermatophore (or droplet of sperm). The female gonopore is located just below the Prosoma on the upper part of the Abdomen (underside) See: http://www.solpugid.com/Courtship%20and%... and http://lanwebs.lander.edu/faculty/rsfox/... for Solifugid anatomy. The male is on the left with his head under her body and not visible. The female is on the right, her head is visible and her abdomen is full of eggs, which can be seen through the integument. They are both about 2 cm in length, although the female is more robust. Family Ammotrechidae. Pictures 4-7 are of the same species from the same place taken in October 2016 to show the entire body. The underside is visible in picture 7. Notice the prominent Racket Organs or Malleoli under the last pair of legs, used for sensory detection. The female gonopore is under 2 genital opercula just below the 4th pair of legs.
Pictures 8 & 9 are of a first instar baby only 2 mm in length.
I found the mating pair hanging upside-down from the overhanging eve of the tool house. I have seen them both frequently in this area and it is probably their preferred territory. Semi-rural residential area, San Cristobal de Las Casas, Chiapas, Mexico, 2,200 meters. This species is described from San Cristobal de Las Casas, with the type specimens in the California Academy of Sciences in San Francisco. The pale white ring at the base of the last segment of the pedipalp (visible on the female) is characteristic of this species. See http://www.solpugid.com/Ammotrecha%20chi.... This is supposed to be a rare species known only from Museum specimens, but I see them frequently and definitely more are on the way!
