Phylloicus monticolus Flint, 1968a:74 [Type locality: Dominica, 1.6 miles west of Pont Casse; NMNH; male; female, larva, pupa, case]. — Botosaneanu 1994:51 [distribution].
This species is most similar to P. lituratus. It is distinguished by the short preanal appendages, the shape of tergum X, and the wing pattern. Flint (1968a, describing very fresh specimens) gives the color as “blue black marked with orange…forewings with two pale pinkish bands.”
Adult. Forewing length 8.6­ 11 mm, n = 13.
Head chestnut brown. Maxillary palps chestnut brown. Antenna twice forewing length; chestnut brown, with narrow patches of pale sensilla on anteromesal surface of each flagellomere. Prothorax golden brown; 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 with posterior fringe of long setae, setae dark. Tibial spur formula 2,4,4. Forewing flat; chestnut brown; with two transverse bands; proximal band pinkish white, not reaching either wing margin, 1/2 width of wing or less; distal band pinkish­white, not reaching either wing margin, 1/2 width of wing or less; with two basal stripes, ivory. Hind wing basal brush present in male, short and light brown.
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 enclosing base of elongate sternum IX; posteromesal process notched, notch deep and round (Fig. 72A, C). Tergum IX deeply notched anteriorly, margins of notch ridged; posterior margin smoothly rounded (Fig. 72B); lateral ridge absent; dorsal pleural setae approximately 3, ventral pleural setae absent (Fig. 72A). Preanal appendage approximately length of tergum X, narrowly elliptic, setae long, but not filamentous or longer than appendage (Fig. 72A, B). Tergum X without basal lobes; basodorsal process short and digitate; basolateral processes absent; apex, in lateral view, truncate, in dorsal view, notched, notch shallow (Fig. 72A, B). Harpago short, rounded; peglike setae many, apical (Fig. 72A, C). Phallic endotheca with paired basolateral lobes, basolateral lobes large and round; phallotremal sclerites average size, longest dimension less than diameter of phallobase; dorsal sclerite ovoid, in dorsal view horseshoe­shaped (Fig. 72D, E).
Female. Preterminal abdominal terga with anteromesal notch. Sternum VII without anteromesal process. Tergum VIII without posterolateral brush; sternum VIII cleft posteromesally to anterior ridge; sternum VIII (Fig. 73C). Tergum IX with very short mesal ridge (Fig. 73B). Sternum IX anterior and posterior lobes darkly sclerotized and striate, with patch of lightly sclerotized cuticle lateral to vaginal opening (Fig. 73A). Tergum X appendage shorter than mesal lobe, base indistinct, apex oblique; mesal lobe lightly sclerotized; digitate lateral processes absent (Fig. 73B). Sternum X with patches of short fine setae posterolaterally to anal opening (Fig. 73A). 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 ring (Fig. 73A).
