Phylloicus amazonas, new speciesFigs. 17, 18, 106The male genitalia of P. amazonas are most similar to those of P. chalybeus, but these two species differ in the distinctive wing pattern of P. amazonas. The wing pattern (Fig. 106) is similar to P. paprockii (Fig. 112), but differs in the black border of the large white patch.Adult. Forewing length 8.2 9 mm, n = 9.Head golden brown. Maxillary palps golden brown, covered with dark brown setae. Antenna twice forewing length; golden brown. Dorsal pterothorax golden brown; ventrolateral thorax golden brown. Legs golden brown. Metathoracic leg of male without posterior fringe. Tibial spur formula 2,4,2. Forewing flat; dark brown; with single transverse band; distal band white, not reaching either wing margin, 1/2 width of wing or less, oval, bordered with black; with single basal stripe, golden; sparse patches of white or ivory setae in basal cells; large dark patch and sparse white setae at location of proximal band (Fig. 106). Hind wing basal brush present in female.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 similar to anterior sterna, sternum IX not elongate. Tergum IX without mesal ridge; posterior margin smoothly rounded (Fig. 17B); lateral ridge absent; dorsal pleural setae approximately 4, ventral pleural setae approximately 2 (Fig. 17A); sternum IX without mesolateral ridges; sternum IX (Fig. 17C). Preanal appendage approximately length of tergum X, of uniform diameter throughout length, setae long, but not filamentous or longer than appendage (Fig. 17A, B). Tergum X without basal lobes; basodorsal process long and digitate; basolateral processes long, length at least twice diameter; apex, in lateral view, rounded, in dorsal view, notched, notch round; apicodorsal and dorsolateral margins bearing single row of short fine setae (Fig. 17A, B). Harpago long, curving mesally and tapering apically; peglike setae absent (Fig. 17A, C). Phallic endotheca with single long apical lobe and paired basolateral lobes, basolateral lobes multilobed; phallotremal sclerites very large, longest dimension twice diameter of phallobase; dorsal sclerite twoarmed, in lateral view Ushaped (Fig. 17D, E).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. 18C). Tergum IX without mesal ridge (Fig. 18B). Sternum IX anterior and posterior lobes darkly sclerotized and striate, with deep sublateral invaginations (Fig. 18A). Tergum X appendage shorter than mesal lobe, base indistinct, apex triangular; mesal lobe lightly sclerotized; digitate lateral processes absent (Fig. 18B). Sternum X with patches of short fine setae posterolaterally to anal opening (Fig. 18A). Vaginal apparatus anterior and posterior sclerites equal in length; anterior sclerite truncate anteriorly, posterolateral projections acute; posterior sclerite ovoid; posterior end of spermatheca a sclerotized ovoid (Fig. 18A).Holotype male: VENEZUELA: Amazonas: Cerro de la Neblina, Basecamp, 00°51'N 66°10'W, 140 m, 1020.ii.1985, Spangler, Faitoute, & Steiner (NMNH).Paratypes: BRAZIL: Amazonas: Manaus, Ponta Negra, 19.xi.1976, Penny — 1 male (INPA); Res.
