Diagnosis. Labium reaching between metacoxae. Hemelytral membrane not reaching apex of body. Genital cup occupying half the length of pygophore. Dorsal rim of pygophore entire medially. Gonocoxites IX elongated, triangular. Chitinellipsen oval, at least twice the size of each sclerotised area of gonapophyses VIII. Laterotergites IX triangular. Distal ductus receptaculi short.

Description. General colour light brown dorsally and brown ventrally. Antennomeres brownish, apex of antennomere III, IV and V dark brown. Coxae with dark brown blotches; femora and tibiae light brown with dark brown punctures; tarsi light brown. Prosterno and mesosternal carina, evaporatorium and abdominal sternites III–IV medially dark brown. Sternites III–VII light brown laterally and with deep punctures; anterolateral angles of sternites dark brown. Trichobothria yellowish. Body small and elongated, convex ventrally ( Figure 4 (a ‒ c)). Proportions of antennomeres I> II <III> IV <V. Labium reaching between the metacoxae; proportions of labial segments I <II> III> IV ( Figure 4 (b)). Anterolateral margins of pronotum serrated along anterior half ( Figure 4 (a)). Hemelytral membrane not reaching apex of body. Surface of evaporatorium with circumvolutions; metathoracic spiracle narrow, with filter system smooth and provided with lateral connections ( Figure 5 (a ‒ c)). Connexivum exposed ( Figure 4 (a)). Measurements in Table 1 .

Male genitalia. Pygophore subquadrangular ( Figure 6a ‒ f); posterolateral angles rounded ( Figure 12 (c ‒ d)). Genital cup occupying half the length of pygophore. Dorsal rim (dr) of pygophore entire medially with 1 + 1 dorsal process; extension of dorsal rim obsolete over segment X. Superior layer of ventral rim (slvr) without processes; median excavation of superior layer of ventral rim (me) concave ( Figure 12 (a ‒ c)); lateral margin of projection of superior layer of ventral rim entire ( Figure 6 (a ‒ b,d)). Inferior layer of ventral rim (ilvr) without process ( Figure 6 (d,f)). Segment X (x) ogival ( Figure 6 (a ‒ b)). Phallus ( Figure 7 (a ‒ c)): dorsal connectives (dc) short, shorter than half the length of phallotheca. Processus capitati (pc) short, not reaching distal margin of phallotheca. Phallotheca (ph) piriform, longer than its width apically. Phallotheca with 1 + 1 dorsal process of phallotheca (dpph) uniformly wide, and three pairs of projections: 1 + 1 ventrobasal (vbpph); 1 + 1 in posterodorsal (pdpph) margin, shorter than dorsal processes of phallotheca; and 1 + 1 small in posterolateral (plpph) margin, rounded. Conjunctiva (cj) with two pairs of processes and two pairs of lobes: median (mlcj) and ventral lobes (vlcj) entirely membranous. Process of vesica (pve) long. Ductus seminis distalis (dsd) long.

Female genitalia. Gonocoxites VIII convex, at least twice as long as laterotergites IX, partially covering gonocoxites IX; posterior margin sinuous. Laterotergites VIII with posterior margin obtusely projected ( Figure 8 (a ‒ b)). Gonocoxites IX swollen, elongated, triangular, with anterior margin concave and posterior margin convex ( Figure 8 (c ‒ d)). Gonapophyses IX with 1 + 1 lateral sclerotised areas placed along with chitinellipsen. Chitinellipsen oval, at least twice the size of each sclerotised area. Laterotergites IX triangular, obtusely projected apically. Ectodermal ductus ( Figure 8 (e ‒ f)): anterior part of thickening of vaginal intima as long as posterior portion of tvi. Proximal ductus receptaculi straight, shorter than the length of vesicular area; diameter of proximal ductus receptaculi larger than internal wall of vesicular area. Median wall of vesicular area enlarged sub-proximally. Distal ductus receptaculi straight, short, diameter equal to diameter of median wall of vesicular area. Vesicular area (va) long, occupying more than half the length of the ductus receptaculi. Anterior annular flange developed. Posterior annular flange thinner than capsula seminalis. Pars intermedialis enlarged. Capsula seminalis globose and larger than pars intermedialis.

Etymology. occultata , from Latin, nominative feminine singular of occultātus, which means hidden, because it was found in the additional series of P. sinuata .

Distribution. Brazil (Rio Grande do Sul) ( Figure 18).

Remarks. The interpretation of the dorsal and ventral views of the phallus of P. sinuata by Grazia and Fernandes (1996) was misconceived. The mobile processes of the phallotheca are dorsal and the processes of the vesica are ventral. We also updated the terminology used for the processes and projections of the phallus, as follows: ′processo 1 da phallotheca, processo 2 da phallotheca, processo 1 da conjunctiva, processo 1 da vesica̍ ( Grazia and Fernandes 1996, p. 353–354) correspond respectively to: posterodorsal projection of phallotheca, ventrobasal projection of phallotheca, dorsal process of phallotheca, and median lobe of conjunctiva.
