Chimarra (Chimarrita) camella Blahnik Fig. 18 A–B

Description.

The female of this species was not previously illustrated. It is included here, since it is the only species of the subgenus for which the female is not illustrated. The female can be distinguished from other species by the nearly linear anterior margin of segment VIII and, especially, by the distinctive, subquadrate invagination of the posteroventral margin of the same segment. The mesal margin of the invagination has a lightly sclerotized, tab-like projection.

Female genitalia. Sternum VII with ventral process; process projecting, subacute, located near middle of segment, as viewed laterally. Segment VIII synsclerous, short dorsally, anterolateral margin nearly straight, indented and narrowed dorsally and ventrally; segment sclerously connected ventrally to sternum IX; anteroventral margin of segment, as viewed ventrally, with subquadrate mesal emargination, extending about ½ length of segment, margins of emargination very distinctly sclerotized, sclerotization extending somewhat posteriorly, mesal margin of emargination with lightly sclerotized tab-like projection. Sternum IX elongate, with paired, angular projections, projections continuous posteriorly with elongate, narrow ventral sclerites; sternum membranous ventrally between paired sclerites, and membranous also laterally from acute basal projection to apex. Tergum IX elongate, narrow, distinctly curved, moderately setose, anteroventrally with apodemes only suggestively developed. Segment X with elongate basal portion, furrowed dorsally, with mesal tract of setae in furrow; apically with pair of small, rounded, setose lobes, each with short apical cercus. Vaginal apparatus largely membranous, sclerites (if present) indistinct.
