Phylloicus plaumanniis similar to P. bidigitatusand obliquus. The forewings of P. plaumanniare 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).
