Phylloicus spectabilis Martynov, 1912:9 View in CoL [Type locality: Peru, Callanga ; ASL; male].

This species is known only from the badly rubbed lectotype male and one paralectotype male, which is missing an abdomen. The modifications of the male abdomen are extremely elaborate in this species. It is similar to a number of other species, but is distinguished by the shape of the lateral sclerite of tergum IV, the arrangement and number of lobes of the coremata ( Fig. 99F View FIGURE 99 ), and the shape of sternum VIII ( Fig. 99C View FIGURE 99 ). The description of color features is based on the paralectotype.

Adult. Forewing length 11.6 mm, n = 2.

Head chestnut brown. Maxillary palps chestnut brown. Antenna chestnut brown, with narrow patches of pale sensilla on anteromesal surface of each flagellomere. Dorsal pterothorax chestnut brown; ventrolateral thorax chestnut brown. Legs chestnut brown. Metathoracic leg of male with posterior fringe of long setae. Tibial spur formula 2,4,4. Forewing flat; chestnut brown; with two transverse bands; proximal band golden, reaching posterior wing margin, at least 1/2 width of wing; distal band golden, not reaching either wing margin, 1/2 width of wing or less; with two basal stripes, golden. Hind wing basal brush present in male, dark brown.

Male. Preterminalic abdominal terga with anteromesal notch. Corematic structures present. Tergum III with sclerotized setose processes of posterior pleural membrane. Tergum IV with paired posterior processes and paired lateral sclerites, mesal coremata and lateral coremata; posterior process truncate; lateral sclerite spatulate, directed laterally; lateral coremata with basal globose lobes and long tubular posterior lobe; mesal coremata bilobed, setose, posterior lobe three times length of anterior lobe. Tergum V without sclerotized modifications ( Fig. 99F View FIGURE 99 ). Sternum VII with short, acute anteromesal process. Sternum VIII enclosing base of elongate sternum IX; posteromesal process absent and posterior of segment semimembranous ( Fig. 99C View FIGURE 99 ). Tergum IX with paired mesal ridges extending length of segment; posterior margin continuous with basodorsal process of tergum X ( Fig. 99B View FIGURE 99 ); lateral ridge absent; dorsal pleural setae approximately 5, ventral pleural setae approximately 3 ( Fig. 99A View FIGURE 99 ). Preanal appendage at least 11/2 times length of tergum X, widest apically, setae filamentous, longer than appendage ( Fig. 99A, B View FIGURE 99 ). Tergum X without basal lobes; basodorsal process long and digitate; basolateral processes absent; apex, in lateral view, rounded, in dorsal view, entire ( Fig. 99A, B View FIGURE 99 ). Harpago rounded; peglike setae many, apical ( Fig. 99A, C View FIGURE 99 ). 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. 99D, E View FIGURE 99 ).

Female. Unknown.
