Author's comments:
Presenta 3 triángulos de color claro que se dibujan en el centro de su abdomen rojizo.
Tanto el prosoma como las patas, son de color marrón. En la parte delantera del opistosoma se dibuja una media circunferencia.
Este adulto mide aproximadamente 7 mm, siendo las hembras de mayor tamaño.
Esta araña es una buena depredadora de la cucaracha alemana (Blattella germanica) y de otras arañas. Se instalan cerca de los anidamientos de esta cucaracha, donde van extendiendo sus hilos.
