Phylloicus "n. sp. 3" Flint, 1996:425

This species can be recognized by the uniform golden color of the forewings. Phylloicus adamsae is distinguished by the very short and wide (often nearly circular) preanal appendages ( Fig. 13A, B View FIGURE 13 ).

Adult. Forewing length 9­11 mm, n = 18.

Head golden brown. Maxillary palps golden brown, covered with dark brown setae. Antennae twice forewing length; chestnut brown. Prothorax golden brown; dorsal pterothorax golden brown; ventrolateral thorax pale tan. Legs pale tan. Metathoracic leg of male with posterior fringe of long setae, setae pale. Tibial spur formula 2,4,4. Forewing flat; golden brown; without colored markings; distal fringe slightly darkened. Hind wing basal brush absent.

Male. Preterminalic abdominal terga without anteromesal notches. Corematic structures absent, terga III­V unmodified, without membranous lobes or sclerotized processes. Sternum VII with short, acute anteromesal process. Sternum VIII enclosing base of elongate sternum IX; posteromesal process notched ( Fig. 13A, C View FIGURE 13 ). Tergum IX without mesal ridge; posterior margin with round narrow mesal projection; thinly sclerotized mesally ( Fig. 13B View FIGURE 13 ); lateral ridge absent; dorsal pleural setae approximately 10, ventral pleural setae approximately 6 ( Fig. 13A View FIGURE 13 ). Preanal appendage less than 2/3 length of tergum X, as long as wide, rounded apically, setae long, but not filamentous or longer than appendage ( Fig. 13A, B View FIGURE 13 ). Tergum X without basal lobes; basodorsal process absent; basolateral processes absent; apex, in lateral view, rounded, in dorsal view, notched, notch shallow and triangular ( Fig. 13A, B View FIGURE 13 ). Harpago short, rounded; peglike setae few, apical ( Fig. 13A, C View FIGURE 13 ). Phallic endotheca with paired basolateral lobes, basolateral lobes tapered apically; phallotremal sclerites average size, longest dimension less than diameter of phallobase; dorsal sclerite ovoid, in dorsal view horseshoe­shaped ( Fig. 13D, E View FIGURE 13 ).

Female. Preterminal abdominal terga without anteromesal notches. Sternum VII with short pointed anteromesal process. Tergum VIII without posterolateral brush; sternum VIII cleft posteromesally to anterior ridge; sternum VIII ( Fig. 14C View FIGURE 14 ). Tergum IX without mesal ridge ( Fig. 14B View FIGURE 14 ). Sternum IX anterior lobes darkly sclerotized and striate, posterior lobes smooth, with patch of lightly sclerotized cuticle lateral to vaginal opening ( Fig. 14A View FIGURE 14 ). Tergum X appendage shorter than mesal lobe, base indistinct, apex oblique; mesal lobe lightly sclerotized; digitate lateral processes absent ( Fig. 14B View FIGURE 14 ). Sternum X with patches of short fine setae posterolaterally to anal opening ( Fig. 14A View FIGURE 14 ). Vaginal apparatus anterior and posterior sclerites equal in length; anterior sclerite truncate anteriorly, posterolateral projections absent; posterior sclerite triangular; posterior end of spermatheca a sclerotized sphere with wide anterior ridge ( Fig. 14A View FIGURE 14 ).

Distribution. Peru.

Etymology. I am pleased to name this species for its collector, Nancy E. Adams, in recognition of her contributions to Neotropical caddisfly research and her assistance during my visits to the Smithsonian Institution.
