Santa Catarina , Seara ( 27°09'S , 52°15'W ); NMNH; male]. Phylloicus plaumanni is similar to P. bidigitatus and obliquus . The forewings of P. plaumanni are a uniform dark brown. Adult. Forewing length 8.6­10.9 mm, n = 30. Head dark brown or black. Maxillary palps dark brown. Antenna twice forewing length; chestnut brown, with narrow patches of pale sensilla on anteromesal surface of each flagellomere. Dorsal pterothorax dark brown; ventrolateral thorax dark brown. Femora dark brown; tibiae dark brown; foretarsi dark brown; mesotarsi golden brown; metatarsi dark brown. Metathoracic leg of male without posterior fringe. Tibial spur formula 2,4,4. Forewing flat; dark brown; without colored markings. Hind wing basal brush present in male. 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 paired mesal ridges extending 1/2 length of segment; posterior margin not distinct from base of tergum X; thinly sclerotized anteromesally ( Fig. 92B ); lateral ridge present; dorsal pleural setae approximately 10, ventral pleural setae absent ( Fig. 92A ); sternum IX with paired mesolateral ridges; sternum IX ( Fig. 92C ). Preanal appendage approximately length of tergum X, narrowly elliptic, setae long, but not filamentous or longer than appendage ( Fig. 92A, B ). Tergum X without basal lobes; basodorsal process absent; basolateral processes absent; apex, in lateral view, acute, in dorsal view, notched, notch deep and round; setose dorsally ( Fig. 92A, B ). Harpago sharply tapered; peglike setae few, apical ( Fig. 92A, C ). Phallic endotheca with paired apicolateral lobes and paired basolateral lobes, basolateral lobes multilobed, apicolateral lobes small and rounded; phallotremal sclerites average size, longest dimension less than diameter of phallobase; dorsal sclerite narrow, width less than height ( Fig. 92D, 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. 93C ). Tergum IX without mesal ridge; covered with short fine pilosity ( Fig. 93B ). Sternum IX anterior lobes smooth and indistinct, posterior lobes striate, with shallow pockets lateral to vaginal opening ( Fig. 93A ). Tergum X appendage longer than mesal lobe, base marked by faint suture line, apex triangular; mesal lobe lightly sclerotized; digitate lateral processes absent ( Fig. 93B ). Sternum X without setae in membrane ( Fig. 93A ). Vaginal apparatus posterior sclerite elongate; anterior sclerite tapered anteriorly, posterolateral projections rounded; posterior sclerite triangular; posterior end of spermatheca a sclerotized ovoid ( Fig. 93A ).
