Phylloicus paprockii , new species

Figs. 82 , 83 , 112

This species is similar to P. amazonas , fenestratus , and obliquus . Phylloicus paprockii is distinguished by forewing color and pattern ( Fig. 112 ), the deep rounded notch of tergum X ( Fig. 82B ), the shape of the harpago, which is sharply tapered ( Fig. 82A, B ), and the morphology of the phallic endotheca and phallotremal sclerites ( Fig. 82D, E ).

Adult. Forewing length 10.1­11.4 mm, n = 3.

Head chestnut brown. Maxillary palps dark brown, covered with golden setae. Antenna twice forewing length; chestnut brown, with narrow patches of pale sensilla on anteromesal surface of each flagellomere. Dorsal pterothorax chestnut brown, lateral margins dark; ventrolateral thorax golden. Femora golden; foretibiae golden; mesotibiae golden; metatibiae dark brown; foretarsi golden; mesotarsi golden; metatarsi dark brown. Metathoracic leg of male without posterior fringe. Tibial spur formula 2,4,4. Forewing flat; dark brown; with two transverse bands; proximal band ivory, reaching posterior wing margin, at least 1/2 width of wing; distal band ivory, not reaching either wing margin, 1/2 width of wing or less, oval; with single basal stripe, white; basal cells clear ( Fig. 112 ). Hind wing basal brush present in female.

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 short mesal ridge extending from anterior notch; posterior margin smoothly rounded ( Fig. 82B ); lateral ridge absent; dorsal pleural setae approximately 10, ventral pleural setae approximately 8 ( Fig. 82A ); sternum IX without mesolateral ridges; sternum IX ( Fig. 82C ). Preanal appendage approximately length of tergum X, of uniform diameter throughout length, setae long, but not filamentous or longer than appendage ( Fig. 82A, 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; with short, rounded setose basolateral paired projections ( Fig. 82A, B ). Harpago long, curving mesally and tapering apically; peglike setae many, mesoventral ( Fig. 82A, C ). Phallic endotheca with single long apical lobe and paired basolateral lobes, basolateral lobes large and round and with digitate apical lobe; phallotremal sclerites very large, longest dimension twice diameter of phallobase; dorsal sclerite two­armed, in lateral view U­shaped ( Fig. 82D, 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. 83C ). Tergum IX with very short mesal ridge ( Fig. 83B ). Sternum IX anterior and posterior lobes darkly sclerotized and striate, punctate, with shallow pockets anterolateral to vaginal opening ( Fig. 83A ). Tergum X appendage longer than mesal lobe, base marked by faint suture line, apex triangular; mesal lobe lightly sclerotized; digitate lateral processes absent ( Fig. 83B ). Sternum X with patches of short fine setae posterolaterally to anal opening ( Fig. 83A ). Vaginal apparatus posterior sclerite elongate; anterior sclerite rounded anteriorly, posterolateral projections absent; posterior sclerite ovoid; posterior end of spermatheca a tiny sclerotized sphere ( Fig. 83A ).

Holotype male: BRAZIL: Minas Gerais: Aldeia de Cachoeira das Pedras, 20°06'49”S, 44°01'25"W, 925 m, 9.x.2000, Paprocki & Isaac ( MZUSP).

Paratypes: BRAZIL: Bahia: Camacá , 400­700 m, 21 Sep­ 30.ix.1991, Becker — 1 male ( NMNH) ; Minas Gerais: Aldeia de Cachoeira das Pedras, 20°06'49”S, 44°01'25"W, 925 m, 9.x.2000, Paprocki & Isaac — 1 female ( UMSP) .

Distribution. Brazil.

Etymology. It is with great pleasure that I name this species for Henrique Paprocki, who collected the type specimen on his family’s land in Minas Gerais.
