Diagnostic description.

Length: 1.81-2.01 mm (avg. 1.89 mm); width: 1.42-1.81 mm (avg. 1.57 mm). This species is very similar to several others in this group, especially P. blairi and to P. erwini , but is unique in a few characters: body elongate (Fig. 7G ), almost parallel-sided, with sides weakly rounded, dark rufescent, with conspicuous ground punctation; frons and epistoma deeply depressed along midline, sparsely but doubly punctate; pronotal gland openings just under halfway back on pronotal disk; pronotal disk with conspicuous secondary punctures throughout, sparser but distinct in middle third; marginal pronotal stria broken with inner ends recurved briefly behind eyes; submarginal pronotal stria short and weakly impressed, in anterior corners only; both propygidium and pygidium with dense secondary punctures; prosternal lobe very short, rounded. Male: basal piece ~ 1/3 length of tegmen; tegmen with sides weakly rounded, apices subacute, weakly separated; tegmen weakly curved, flatter toward apex, in lateral view; weak medioventral process present in basal 1/3; median lobe ~ 1/2 tegmen length, basal apodemes abruptly thinner near bases.

Etymology.

We name this species for the state of its primary occurrence, Paraná, Brazil.

Distribution.

This species is only known from a relatively small area in coastal southeastern Brazil.

Remarks.

The description presents all of this species’ distinguishing characters.
