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) than in the other three species. The preanal appendage of P. pulchrus is shorter and the harpago is rounded apically ( Fig. 94A, B, C).

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); basal cells alternating orange setae and iridescent membrane ( Fig. 114). 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); lateral ridge absent; dorsal pleural setae approximately 7, ventral pleural setae absent ( Fig. 94A); sternum IX with paired mesolateral ridges; sternum IX ( Fig. 94C). 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). 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). Harpago large, rounded; peglike setae many, mesoventral ( Fig. 94A, C). 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).

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