Chileria colla Carvalho and Carpintero, 1991: 33 [n. sp.]; Schuh, 1995: 97 [catalog].

DIAGNOSIS (fig. 7): Recognized by the erect, spinelike anterior process on the right margin of the aperture of the genital capsule; posterior process of the right margin of the aperture directed medially, with small spines; left margin of aperture with anterior process simple, directed laterally, and posterior process slightly denticulate, directed laterally and longer than anterior process; vesica with apical ramus with the two portions apically expanded, dorsal portion long, slightly longer than ventral portion; anteriorly directed ramus of vesica with shorter (lateral) portion from strongly serrate to nearly bifurcate.

Chileria colla is very similar in dorsal coloration (fig. 1) and vesica structure (fig. 7) to the new species Ch. andina . Chileria colla can be distinguished from Ch. andina by the shape of the anterior right tergal process of the aperture of the genital capsule, which is a simple, erect spine (fig. 7), whereas in Ch. andina this tergal process is transversely elongate and serrate (fig. 6). The tergal processes of the left margin are similar, but in Ch. colla the anterior process is directed laterally (fig. 7), whereas in Ch. andina this process is directed dorsally (fig. 6). The structure of the vesica is also similar in the two species but in Ch. colla the dorsal portion of the apical rami is much longer (fig. 7) than in Ch. andina (fig. 6).

DISTRIBUTION: Chileria colla is distributed from Bolivia to northern Argentina (Salta) (fig. 9). Bolivia is a new country record for this species.

HOSTS: Not known for this species.

DISCUSSION: The examined paratype is topotypic with the holotype ( Carvalho and Carpintero, 1991). This paratype has the longer (medial) portion of the anteriorly directed ramus (fig. 7, black arrow) slightly turned caudad. Another one of the male paratypes from the same locality has its genitalia dissected and glued to a card, in which the same portion of the ramus is directed cephalad (fig. 7, dotted line). The Bolivian specimens examined also have this ramus directed cephalad, but the right portion of the posteriorly directed rami is serrate, not bifurcate as in the Argentinean paratype examined (fig. 7, gray arrow). I consider these differences intraspecific variations because of the same structure of the tergal processes on the genital capsule (fig. 7).

The gray arrow on C. colla indicates where variation in serration on the short (lateral) portion of the anteriorly directed ramus occurs. Black arrow indicates position of longer (medial) portion of ramus in paratype, and dotted line indicates usual position of this portion of the ramus in other specimens.
