Phylloicus farri Flint, 1968b:56 [Type locality: Jamaica, St. Andrew, Hope River near Newcastle at mile post 16.5; NMNH; male; female, larva, pupa, case]. — Denning et al. 1983:188 [type species of Murielia]. — Flint et al. 1999b:73 [returned to Phylloicus].
Phylloicus farri is easily recognized by the very long (at least twice length of genital capsule, narrow preanal appendages (Fig. 49A, B). The modifications of male tergum IV are also distinctive (Fig. 49F).
Adult. Forewing length 7.7­11.3 mm, n = 14.
Head golden brown. Maxillary palps golden brown. Antenna twice forewing length; dark brown, with narrow patches of pale sensilla on anteromesal surface of each flagellomere. Dorsal pterothorax golden brown; ventrolateral thorax golden. Legs golden. Metathoracic leg of male without posterior fringe. Tibial spur formula 2,4,4. Forewing flat; golden brown; with single transverse band; proximal band tan, reaching posterior wing margin, at least 1/2 width of wing; proximal half of basal cells clear. Hind wing basal brush present in male, pale.
Male. Preterminalic abdominal terga with anteromesal notch. Corematic structures present. Tergum IV with expanded lateral flanges, mesal coremata and lateral coremata; lateral coremata with basal globose lobes and long tubular posterior lobe; mesal coremata single­lobed, single­lobed, originating broadly from membrane of tergum IV­V. Tergum V without sclerotized modifications (Fig. 49F). Sternum VII with short, acute anteromesal process. Sternum VIII similar to anterior sterna, sternum IX not elongate. Tergum IX without mesal ridge; posterior margin not distinct from base of tergum X; notched anteromesally (Fig. 49B); lateral ridge absent; dorsal pleural setae approximately 6, ventral pleural setae absent (Fig. 49A); sternum IX with paired mesolateral ridges; sternum IX (Fig. 49C). Preanal appendage at least 11/2 times length of tergum X, of uniform diameter throughout length, setae long, but not filamentous or longer than appendage (Fig. 49A, B). Tergum X without basal lobes; basodorsal process absent; basolateral processes absent; apex, in lateral view, acute, in dorsal view, notched, notch triangular; with short setae basodorsally (Fig. 49A, B). Harpago slightly tapered; peglike setae tiny, mesal (Fig. 49A, C). Phallotremal sclerites average size, longest dimension less than diameter of phallobase; dorsal sclerite ovoid, in dorsal view horseshoe­shaped (Fig. 49D, E).
Female. Abdominal terga I­III dark brown laterally. 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. 50C). Tergum IX without mesal ridge (Fig. 50B). Sternum IX anterior lobes smooth and indistinct, posterior lobes striate, with shallow pockets anterolateral to vaginal opening (Fig. 50A). Tergum X appendage longer than mesal lobe, base indistinct, apex triangular; mesal lobe lightly sclerotized; digitate lateral processes absent (Fig. 50B). Sternum X with semisclerotized plates marking anal opening (Fig. 50A). Vaginal apparatus anterior and posterior sclerites equal in length; anterior sclerite rounded anteriorly, posterolateral projections acute; posterior sclerite triangular; posterior end of spermatheca a sclerotized ring (Fig. 50A).
