Figs. 45, 46
The forewings of P. elektoros are a golden ochre color, with stripes of pale tan setae between the wing veins. This species is most similar to P. auratus and brevior; P. elektoros differs from the first two in wing coloring, the lack of coremata or tergal modifications, and in the long digitate dorsal process of the phallic endotheca. Tergum X is entire, posteriorly (Fig. 45B)
Adult. Forewing length 9.6­10.5 mm, n = 32.
Head golden, darker anteriorly, setae on warts golden. Maxillary palps golden, covered with dark brown setae. Antenna twice forewing length; anterior surface chestnut brown, posterior surface golden, with narrow patches of pale sensilla on anteromesal surface of each flagellomere. Dorsal pterothorax golden brown, lateral margins darker; ventrolateral thorax golden. Femora golden; foretibiae golden; mesotibiae chestnut brown; metatibiae chestnut brown; foretarsi golden; mesotarsi chestnut brown; metatarsi chestnut brown. Metathoracic leg of male with posterior fringe of long setae. Tibial spur formula 2,4,4. Forewing flat; golden ochre; with longitudinal stripes; stripes pale tan. 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 enclosing base of elongate sternum IX; posteromesal process absent and posterior margin irregular (Fig. 45A, C). Tergum IX without mesal ridge; posterior margin smoothly rounded; thinly sclerotized anteromesally, anterior ridge obsolete mesally (Fig. 45B); lateral ridge present; dorsal pleural setae approximately 10, ventral pleural setae approximately 5 (Fig. 45A). Preanal appendage less than 2/3 length of tergum X, of uniform diameter throughout length, setae long, but not filamentous or longer than appendage (Fig. 45A, B). Tergum X without basal lobes; basodorsal process absent; basolateral processes absent; apex, in lateral view, truncate, in dorsal view, entire; covered with short setae dorsally (Fig. 45A, B). Harpago slightly tapered; peglike setae few, apical (Fig. 45A, C). Phallic endotheca with single long apical lobe and paired basolateral lobes, basolateral lobes multilobed; phallotremal sclerites average size, longest dimension less than diameter of phallobase; dorsal sclerite rectangular, width greater than height (Fig. 45D, E).
Female. Preterminal abdominal terga with anteromesal notch. Sternum VII with short pointed anteromesal process. Tergum VIII without posterolateral brush; sternum VIII with shallow posteromesal notch, or posterior margin entire; sternum VIII (Fig. 46C). Tergum IX without mesal ridge (Fig. 46B). Sternum IX anterior and posterior lobes darkly sclerotized and striate, with patch of lightly sclerotized cuticle laterally (Fig. 46A). Tergum X appendage shorter than mesal lobe, base indistinct, apex oblique; mesal lobe lightly sclerotized; digitate lateral processes absent (Fig. 46B). Sternum X with patches of short fine setae posterolaterally to anal opening (Fig. 46A). Vaginal apparatus anterior and posterior sclerites equal in length; anterior sclerite truncate anteriorly, posterolateral projections absent; posterior sclerite triangular; posterior end of spermatheca a sclerotized cone (Fig. 46A).
