Figs. 59 View FIGURE 59 , 60 View FIGURE 60 , 111 View FIGURES 109-112. — 109

Phylloicus iridescens Banks, 1941:397 View in CoL [Type locality: Dominican Republic, Constanza to V. Nuevo; MCZ; male]. — Flint 1967:18 [lectotype male].

This species is most similar to P. cubanus View in CoL , pulchrus View in CoL , and superbus View in CoL . In P. iridescens View in CoL the orange bands of the forewing are narrower ( Fig. 111 View FIGURES 109-112. — 109 ) than in the other three species, and the male genitalia are distinguished by a tapering harpago.

Adult. Forewing length 8.1­9.5 mm, n = 12.

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 dark brown; ventrolateral thorax chestnut brown. Femora golden; foretibiae dark brown; mesotibiae dark brown; metatibiae dark brown; foretarsi dark brown; mesotarsi white; metatarsi dark brown. Metathoracic leg of male without posterior fringe. Tibial spur formula 2,4,2. Forewing flat; dark brown; with two transverse bands; proximal band orange, reaching posterior wing margin, at least 1/2 width of wing; distal band orange, beginning at anterior wing margin, at least 1/2 width of wing; basal cells without setae, membrane iridescent ( Fig. 111 View FIGURES 109-112. — 109 ). 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 full length of segment; posterior margin continuous with basodorsal process of tergum X ( Fig. 59B View FIGURE 59 ); lateral ridge present; dorsal pleural setae approximately 15, ventral pleural setae absent ( Fig. 59A View FIGURE 59 ); sternum IX with paired mesolateral ridges; sternum IX ( Fig. 59C View FIGURE 59 ). Preanal appendage less than 2/3 length of tergum X, narrowly elliptic, setae long, but not filamentous or longer than appendage ( Fig. 59A, B View FIGURE 59 ). Tergum X without basal lobes; basodorsal process short and digitate; basolateral processes absent; apex, in lateral view, rounded, in dorsal view, notched, notch shallow ( Fig. 59A, B View FIGURE 59 ). Harpago rounded; peglike setae few, apical ( Fig. 59A, C View FIGURE 59 ). Phallic endotheca with paired apicolateral lobes, apicolateral lobes rounded and with digitate apical lobe; phallotremal sclerites very large, longest dimension twice diameter of phallobase; dorsal sclerite two­armed, in lateral view U­shaped ( Fig. 59D, E View FIGURE 59 ).

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. 60C View FIGURE 60 ). Tergum IX with mesal ridge extending 1/3 length of segment ( Fig. 60B View FIGURE 60 ). Sternum IX anterior lobes smooth and indistinct, posterior lobes striate, without distinct area of thin cuticle or invagination ( Fig. 60A View FIGURE 60 ). Tergum X appendage longer than mesal lobe, base distinct, apex rounded; mesal lobe lightly sclerotized; digitate lateral processes absent ( Fig. 60B View FIGURE 60 ). Sternum X without setae in membrane ( Fig. 60A View FIGURE 60 ). Vaginal apparatus posterior sclerite elongate; anterior sclerite rounded anteriorly, posterolateral projections absent; posterior sclerite triangular; posterior end of spermatheca a sclerotized cone ( Fig. 60A View FIGURE 60 ).
