Phylloicus pulchrus Flint, 1964:65 [Type locality: Puerto Rico, Maricao Forest ; NMNH; male].

Phylloicus pulchrus is most similar to the other Antillean species P. cubanus , iridescens , and superbus . In P. pulchrus the orange bands of the forewing are wider ( Fig. 114 View FIGURES 113-116. — 113 ) than in the other three species. The preanal appendage of P. pulchrus is shorter and the harpago is rounded apically ( Fig. 94A, B, C View FIGURE 94 ).

Adult. Forewing length 7­7.9 mm, n = 38.

Head dark brown. Maxillary palps dark brown. Antenna twice forewing length; dark brown, with narrow patches of pale sensilla on anteromesal surface of each flagellomere. Dorsal pterothorax chestnut brown; ventrolateral thorax pale tan. Legs pale tan. Metathoracic leg of male without posterior fringe. Tibial spur formula 2,4,2. Forewing flat; dark brown; with two transverse bands; proximal band orange, extending from anterior to posterior wing margin, wide, at least 1/6 wing length; distal band orange, extending from anterior to posterior wing margins, wide, at least 1/6 wing length, with orange setae along distal wing margin ( Fig. 114 View FIGURES 113-116. — 113 ); basal cells alternating orange setae and iridescent membrane ( Fig. 114 View FIGURES 113-116. — 113 ). Hind wing basal brush absent.

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 2/3 length of segment; posterior margin smoothly rounded ( Fig. 94B View FIGURE 94 ); lateral ridge absent; dorsal pleural setae approximately 7, ventral pleural setae absent ( Fig. 94A View FIGURE 94 ); sternum IX with paired mesolateral ridges; sternum IX ( Fig. 94C View FIGURE 94 ). 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. 94A, B View FIGURE 94 ). Tergum X without basal lobes; basodorsal process long and digitate; basolateral processes absent; apex, in lateral view, acute, in dorsal view, notched, notch shallow ( Fig. 94A, B View FIGURE 94 ). Harpago large, rounded; peglike setae many, mesoventral ( Fig. 94A, C View FIGURE 94 ). Phallic endotheca with paired basolateral lobes, basolateral lobes tapered apically; phallotremal sclerites very large, longest dimension twice diameter of phallobase; dorsal sclerite two­armed, in lateral view U­shaped ( Fig. 94D, E View FIGURE 94 ).

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. 95C View FIGURE 95 ). Tergum IX with mesal ridge extending length of segment (as in Fig. 41B View FIGURE 41 ). Sternum IX anterior lobes smooth and indistinct, posterior lobes striate, with shallow pockets lateral to vaginal opening ( Fig. 95A View FIGURE 95 ). Tergum X appendage shorter than mesal lobe, base distinct, apex rounded; mesal lobe lightly sclerotized; digitate lateral processes absent (as in Fig. 41B View FIGURE 41 ). Sternum X with patches of short fine setae posterolaterally to anal opening ( Fig. 95A View FIGURE 95 ). 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 sphere with wide anterior ridge ( Fig. 95A View FIGURE 95 ).
