Phylloicus distans Navás, 1918:226 [ Type locality: Chile , Marga­Marga, Los Perales; MZB; male]. — Flint 1974a:84 [to synonymy]. Phylloicus aculeatus is easily recognized. It is the only calamoceratid known from the Chilean subregion. The long, paired digitate processes of tergum X ( Fig. 11A, B ) are plainly visible even in uncleared specimens. The inferior appendages appear one­segmented, with the harpago large, not distinct from the coxopodite, and with numerous peglike setae on the mesoventral surface. Adult. Forewing length 10.3­12.5 mm, n = 147. Head dark brown. Maxillary palps dark brown. Antenna twice forewing length; chestnut brown. Dorsal pterothorax dark brown; ventrolateral thorax golden brown. Legs golden brown. Metathoracic leg of male with posterior fringe of long setae. Tibial spur formula — 2,4,4. Forewing flat; chestnut brown; without colored markings. Male. Preterminalic abdominal terga without anteromesal notches. Corematic structures absent, terga III­V unmodified, without membranous lobes or sclerotized processes. Sternum VII without anteromesal process. Sternum VIII similar to anterior sterna, sternum IX not elongate. Tergum IX without mesal ridge; posterior margin with irregular mesal projection; dorsomesal lobe covered with fine ridged sculpturing ( Fig. 11B ); lateral ridge absent; dorsal pleural setae approximately 15, ventral pleural setae absent ( Fig. 11A ); sternum IX without mesolateral ridges; sternum IX ( Fig. 11C ). Preanal appendage less than 2/ 3 length of tergum X, widest near base, setae long, but not filamentous or longer than appendage ( Fig. 11A, B ). Tergum X without basal lobes; basodorsal process absent; basolateral processes long, length at least twice diameter; apex, in lateral view, with ventral projection, in dorsal view, notched, notch deep and triangular; with small setose mesal lobe at mid­length; with longitudinal row of short setae sublaterally; lateral margins extending over bases of paired, truncate apical processes ( Fig. 11A, B ). Harpago large, nearly equal to coxopodite and with base indistinct from coxopodite; peglike setae many, mesoventral ( Fig. 11A, C ). Phallic endotheca with paired apicolateral lobes and paired basolateral lobes, basolateral lobes large and round, apicolateral lobes large and rounded; phallotremal sclerites average size, longest dimension less than diameter of phallobase; dorsal sclerite ovoid, in dorsal view horseshoe­shaped ( Fig. 11D, E ). Female. Preterminal abdominal terga without anteromesal notches. Sternum VII without anteromesal process. Tergum VIII without posterolateral brush; sternum VIII cleft posteromesally to anterior ridge; sternum VIII ( Fig. 12C ). Tergum IX without mesal ridge ( Fig. 12B ). Sternum IX anterior and posterior lobes darkly sclerotized and striate, without distinct area of thin cuticle or invagination ( Fig. 12A ). Tergum X appendage shorter than mesal lobe, base marked by faint suture line, apex rounded; mesal lobe lightly sclerotized; digitate lateral processes long, at least twice diameter, or absent ( Fig. 12B ). Sternum X without setae in membrane ( Fig. 12A ). Vaginal apparatus anterior and posterior sclerites equal in length; anterior sclerite truncate anteriorly, posterolateral projections rounded; posterior sclerite ovoid; posterior end of spermatheca membranous ( Fig. 12A ).
