Phylloicus cubanus Banks, 1924:445 [Type locality: Cuba; MCZ; male]. — Flint 1967:18 [male]. — Botosaneanu & Sykora 1973:399 [male, larva, pupa]. — Botosaneanu 1994:468 [larva].

This species is most similar to P. iridescens , pulchrus , and superbus , all of which have a similar pattern of orange bands across brown wings. Phylloicus cubanus and P. superbus are very similar (see discussion under P. superbus ), with an apically expanded harpago ( Fig. 41A, C ), but P. cubanus is the smaller of the two species.

Adult. Forewing length 7.7­9.9 mm, n = 28.

Head golden brown. Maxillary palps dark brown, covered with dark brown setae. Antenna twice forewing length; chestnut brown, with narrow patches of pale sensilla on anteromesal surface of each flagellomere. Dorsal pterothorax golden brown; ventrolateral thorax golden. Femora golden; foretibiae golden; mesotibiae golden; metatibiae dark brown; tarsi golden. 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, wide, at least 1/6 wing length; distal band orange, extending from anterior to posterior wing margins, wide, at least 1/6 wing length ( Fig. 108 ). 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 deeply notched anteriorly, margins of notch ridged; posterior margin continuous with basodorsal process of tergum X ( Fig. 41B ); lateral ridge absent; dorsal pleural setae approximately 15, ventral pleural setae absent ( Fig. 41A ); sternum IX with paired mesolateral ridges; sternum IX ( Fig. 41C ). Preanal appendage less than 2/3 length of tergum X, narrowly elliptic, setae long, but not filamentous or longer than appendage ( Fig. 41A, 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; with paired short longitudinal ridges at mid­length ( Fig. 41A, B ). Harpago rounded; peglike setae many, apical ( Fig. 41A, C ). Phallic endotheca with paired apicolateral lobes and paired basolateral lobes, basolateral lobes tapered apically, apicolateral lobes large and rounded; phallotremal sclerites very large, longest dimension twice diameter of phallobase; dorsal sclerite two­armed, in lateral view U­shaped ( Fig. 41D, 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. 42C ). Tergum IX with mesal ridge extending length of segment ( Fig. 42B ). Sternum IX anterior lobes smooth and indistinct, posterior lobes striate, with shallow pockets anterolateral to vaginal opening ( Fig. 42A ). Tergum X appendage length equal to mesal lobe, base distinct, apex rounded; mesal lobe lightly sclerotized; digitate lateral processes absent ( Fig. 42B ). Sternum X with patches of short fine setae posterolaterally to anal opening ( Fig. 42A ). Vaginal apparatus anterior and posterior sclerites equal in length; anterior sclerite rounded anteriorly, posterolateral projections acute; posterior sclerite ovoid; posterior end of spermatheca a sclerotized ring ( Fig. 42A ).
