Phylloicus trichothylax , new species
Fig. 103 View FIGURE 103
Phylloicus trichothylax is known only from a single teneral male, and thus details of coloration are difficult to identify and the forewings are too twisted for accurate measurement. It is distinguished by the abdominal coremata, which consist of a pair of invaginated membranous pouches containing long setae and a single, eversible, digitate membranous lobe ( Fig. 103F View FIGURE 103 ), and by the long digitate basodorsal process of tergum X ( Fig. 103A, B View FIGURE 103 ).
Adult. Head golden brown, with dorsomesal crest of golden brown setae. Maxillary palps dark brown. Antenna golden brown. Dorsal pterothorax golden brown; ventrolateral thorax golden brown. Legs golden brown. Metathoracic leg of male with posterior fringe of long setae. Tibial spur formula 2,4,4. Forewing flat. Hind wing basal brush present in male.
Male. Preterminalic abdominal terga with anteromesal notch. Corematic structures present. Tergum IV with expanded lateral flanges, mesal coremata; mesal coremata an invaginated setose pouch, enclosing small, digitate eversible lobe. Tergum V without sclerotized modifications ( Fig. 103F View FIGURE 103 ). Sternum VII without anteromesal process. Sternum VIII similar to anterior sterna, sternum IX not elongate. Tergum IX with paired mesal ridges extending length of segment; posterior margin smoothly rounded; thinly sclerotized anteromesally ( Fig. 103B View FIGURE 103 ); lateral ridge present; dorsal pleural setae approximately 8, ventral pleural setae approximately 6 ( Fig. 103A View FIGURE 103 ); sternum IX without mesolateral ridges; sternum IX ( Fig. 103C View FIGURE 103 ). Preanal appendage shorter than tergum X, but greater than 2/3 length, narrowly elliptic, setae long, but not filamentous or longer than appendage ( Fig. 103A, B View FIGURE 103 ). Tergum X without basal lobes; basodorsal process long and digitate; basolateral processes absent; apex, in lateral view, truncate, in dorsal view, entire ( Fig. 103A, B View FIGURE 103 ). Harpago slightly tapered; peglike setae few, apical ( Fig. 103A, C View FIGURE 103 ). Phallotremal sclerites average size, longest dimension less than diameter of phallobase; dorsal sclerite ovoid, in dorsal view horseshoeshaped ( Fig. 103D, E View FIGURE 103 ).
Female. Unknown.
Holotype male: ECUADOR: Cotopaxi: Latacunga , 13 km W, 1372 m, 1.vii.1975, Langley & Cohen ( NMNH).
Distribution. Ecuador.
Etymology. Trichothylax, from the Greek trichos, “hair” and thylax, “pouch,” for the setaeenclosing membranous pouch of tergum IV.
