Phylloicus fenestratus Flint, 1974b:139   [Type locality: Surinam, Nickerie River, Stondansi ; RNH; male]; 1996:425 [distribution].

Phylloicus fenestratus   is distinguished by the forewing pattern, which consists of a chestnut brown wing with narrow proximal and distal bands of white, a patch of white in the proximal half of cell Cu 2, and cells R 1, R, thyridial and 1 st M cells clear proximally. The male abdomen is distinguished by the absence of — coremata or tergal modifications, and tergum X is fusiform ( Fig. 51A, B View FIGURE 51 ). The phallus is sharply curved basally, although the curvature varies in degree ( Fig. 51D View FIGURE 51 ).

Adult. Forewing length 7.3­9.2 mm, n = 53.

Head chestnut brown, with dorsomesal crest of chestnut brown setae. Maxillary palps dark brown. Antenna twice forewing length; chestnut brown, with narrow patches of pale sensilla on anteromesal surface of each flagellomere. Dorsal pterothorax chestnut brown; ventrolateral thorax golden brown. Femora golden brown; foretibiae golden brown; mesotibiae dark brown; metatibiae dark brown; foretarsi golden brown; mesotarsi white; metatarsi dark brown. Metathoracic leg of male without posterior fringe. Tibial spur formula 2,4,4. Forewing flat; chestnut brown; with two transverse bands; proximal band white, reaching posterior wing margin, at least 1/2 width of wing, narrow, less than 10 setae wide; distal band white, beginning at anterior wing margin, at least 1/2 width of wing, narrow, less than 10 setae wide; with single basal stripe, white; proximal half of basal cells clear. Hind wing basal brush present in male and female, dark brown; female brush short.

Male. Preterminalic abdominal terga with anteromesal notch. 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 with mesal ridge extending full length of segment; posterior margin notched ( Fig. 51B View FIGURE 51 ); lateral ridge present; dorsal pleural setae approximately 15, ventral pleural setae approximately 2 ( Fig. 51A View FIGURE 51 ); sternum IX with paired mesolateral ridges; sternum IX ( Fig. 51C View FIGURE 51 ). Preanal appendage shorter than tergum X, but greater than 2/3 length, of uniform diameter throughout length, setae long, but not filamentous or longer than appendage ( Fig. 51A, B View FIGURE 51 ). Tergum X without basal lobes; basodorsal process absent; basolateral processes absent; apex, in lateral view, acute, in dorsal view, entire; covered with short setae basodorsally ( Fig. 51A, B View FIGURE 51 ). Harpago slightly tapered; peglike setae tiny, mesal ( Fig. 51A, C View FIGURE 51 ). Phallic endotheca with paired apicolateral lobes and paired basolateral lobes, basolateral lobes digitate, apicolateral lobes rounded and setose; phallotremal sclerites average size, longest dimension less than diameter of phallobase; dorsal sclerite ovoid, in dorsal view horseshoe­shaped ( Fig. 51D, E View FIGURE 51 ).

Female. Preterminal abdominal terga with anteromesal notch. Sternum VII with short pointed anteromesal process. Tergum VIII without posterolateral brush; sternum VIII cleft posteromesally to anterior ridge; sternum VIII ( Fig. 52C View FIGURE 52 ). Tergum IX without mesal ridge ( Fig. 52B View FIGURE 52 ). Sternum IX anterior and posterior lobes darkly sclerotized and striate, with deep sublateral invaginations ( Fig. 52A View FIGURE 52 ). Tergum X appendage longer than mesal lobe, base distinct, apex rounded; mesal lobe lightly sclerotized; digitate lateral processes absent ( Fig. 52B View FIGURE 52 ). Sternum X with single pair of fine setae in membrane lateral to anal opening ( Fig. 52A View FIGURE 52 ). 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 cone ( Fig. 52A View FIGURE 52 ).
