Andotypus Spangler, 1979

Known distribution. The genus contains two species – the widespread Andotypus ashworthi Spangler, 1979 , and Andotypus sp. nov. (to be described by FIKÁýEK et al. 2014) known from a single female from Parque Nacional Nahuelbuta (La Araucanía Region). The complete list of known specimens and localities was provided by FIKÁýEK et al. (2014) and these data were used here for estimating the potential distribution of the genus.

Results of the model of the potential distribution. Number of occurrence points analyzed: 44. Training AUC: 0.980. Treshhold for equal training sensitivity and speci¿city: 0.086. Treshhold for maximum sensitivity and speci¿city: 0.063. Most contributing climatic layers: bio19 – precipitation in coldest quarter of the year (58 %), bio15 – precipitation seasonality (18.5 %), bio17 – precipitation of driest quarter of the year (17.3 %). The maximum sensitivity/speci¿city treshhold was used for the prediction, as the area of potential distribution predicted using equal sensitivity/speci¿city did not cover all actual records of the genus.

Potential distribution. Four isolated regions were predicted as potential distribution for the genus: the coastal area in sourthern Bío-Bío and northern Araucanía Regions (ca. between Concepción and Carahue), a large area ranging from southernmost Bío-Bío in the Andes Mts. (ca. Reserva Nacional Ralco and volcan Callaqui) through the whole width of Chile south to ca. 46°S, coastal areas south of Golfo de Penas between ca. 47.5– 51°S, and a small coastal area between ca. 52– 54°S. The species was actually recorded in all these regions except the southernmost one.

Biology. Usually collected using meat/cheese-baited pitfall traps in forested areas, also found by sifting leaf-litter and accumulations of decaying plant matter, probably including beach drift ( SPANGLER 1979c, FIKÁýEK et al. 2014).
