Periglischrus paravargasi n. sp., protonymph. (68) venter; (69) dorsum, scale ---^ 200 of subtenninal adanal setae; first pair posterior to sternal plate minute, all others small. Dor- sum: Peritreme dorsal, short, lying over III. Posterior quarter of dorsal plate superficial- ly divided from anterior portion by narrow transverse band of lightlv sclerotized integu- ment; dorsal plate slightly ornamented with small light and dark areas of inegular shapes and small circular pores or setal bases. Dorsal podosoma with five pairs of rather large setae lateral to dorsal plate; first two pairs antero- lateral to dorsal plate at level over coxa I; middle two pairs anterior to peritremes and lat- eral to dorsal plate at level over coxa II; fifth pair posterior to stigmata. Legs: Coxa I with both proximal and distal setae small; coxa II with anterolateral seta medium sized, but pos- terolateral seta rather large; anterolateral seta of coxa III small, spinelike, and posterolateral seta more slender and somewhat longer; median seta of coxa IV small. Ventral leg setae small, some spinclike. Antero- and posterolateral setae of legs small to medium sized, larger setae often slightly recurved. One or two distal dorsal setae of trochanters II-IV; femora, patella, and tibiae I-IV relativelv large; most other leg setae small to medium sized, except certain proximal setae of some femora, patella and tibiae minute. Gnathosoma: Gnathosomal and one pair of hypo- stomal setae small, slender; other hypostomal setae absent or inapparent. Palpal setae small, some spinelike; two pairs of laterodistal setae of palpal tibia short, peglike. Mediodistal lobe of papal tibia absent. Measurements: Idiosoma length, 422 /i; greatest width, 329 fx. Sternal plate length, 147 /i; greatest width, 121 /t. Ster- nal setae length, 14-2
