Aysenia araucana Ramírez

Fig. 5

Aysenia araucana Ramírez 2003: 65 (male holotype and female paratype from Chile, Biobío Region (VIII), Biobío Province, El Manzano, nr. Contulmo, ca. S38°01’, W73°20’, 3–5.III.1986, L. Peña; deposited in AMNH, re-examined). González & Ramírez 2012: 10.

Updated diagnosis. It is similar to Aysenia paposo new species by having moderately wrapped copulatory ducts, long embolus and relatively small primary conductor, but can be distinguished by the short extension of the primary conductor in retrolateral view, and the angle of the margin of tegulum and cymbium of about 120° (compare fig. 1d and Ramírez 2003: fig. 25B), and the left-right copulatory ducts in the female vulva contiguous and clearly coiled (compare fig. 2c and Ramírez 2003: fig. 25E).

Variability. In addition of the variations recorded in Ramírez (2003) and González & Ramírez (2012), we founded that some specimens have a more elongate carapace and abdomen than in the type series (compare Fig. 5 with illustrations on those references).

Distribution. Widely distributed through northern, central and southern Chile, from Atacama Region (II) to Osorno Province in Los Lagos Region (X).
