General color brownish with adpressed fine silvery and yellowish hairs on the integument (Fig. 27), with head, pleural, and ventral portions of thorax, scutellum base, and sternites darkened. Head with adpressed fine short silvery hairs, with short and narrow median Vshaped glabrous stripe running from transversal sulcus to level of antennal insertion. Rostrum brownish, with fine sparse erect yellowish hairs; spines of first two segments brownish. Antennal segment I with ciliate, erect, long, sparse yellowish hairs (Fig. 29); other segments with fine, short, recumbent, and more numerous yellowish hairs. Antennal segments I and II yellowish with large sub-basal and subapical blackish rings, sub-basal ring on segment I larger; antennal segments III and IV brownish, antennal segment III with faint sub-basal yellow ring. Clypeal spine absent (Figs. 27–28). Thorax: dorsal portion of pronotum brighter; hind lobe of pronotum with two pairs of faint brownish stripes in middle and lateral positions; hind margin brownish. Integument with fine yellowish hairs, these short and decumbent on dorsal portion of prothorax and erect and long on mesopleura, mesosternum, scutellum base, metapleura, and metasternum; disc of fore lobe of pronotum glabrous with longitudinal furrow and pair of stripes between spines of fore lobe covered by short adpressed silvery hairs. Spines of fore and hind lobe of pronotum and scutellum yellowish; base of scutellum brownish. Lateral ridge from tubercles of anterolateral angles more developed on fore lobe of pronotum, this covered with short, fine, yellowish hairs and complete in hind lobe of pronotum, reaching spines of humeral angles, where it is brighter, glabrous, a little larger, shallower. Tubercle of post-scutellum and spine of metanotum brownish, latter with apex brighter. Coxae brownish with apical portion yellowish. Procoxa with poorly defined median brighter ring (Fig. 30) and five spines at inner face, laid out longitudinally; two of them subapical and forming a pair together. Legs yellowish with yellowish fine long and short hairs, much denser and longer on the foreleg. Femur with subapical large brownish rings with median portion a little brighter, fore femur also with well-defined basal darkened rings (Figs. 27, 31–33). Armature of ventral face of fore femur with one thin spine on basal portion; four spines more developed, intermixed with less developed ones, totaling ten on right leg and eleven on left leg; on inner face there are seven spines: apical ones more developed and basal ones showing different arrangements between two legs (Figs. 31–33). Hind femora with pair of apical short spines (Figs. 37–38). Tibiae with sub-basal rings, and apices darkened (Fig. 34). Markings of femora and tibiae more intense on fore legs and very faint on hind ones. Fore tarsi as darkened as tibial apex, mid and hind tarsi faintly darkened. Forewings surpassing tip of abdomen; brownish with yellowish irregular spots, resulting in variegated appearance; veins yellowish; pterostigma with a large reddish spot (Fig. 39); two closed cells (Figs. 39–40). Abdomen: sternites brownish and little brighter and keeled medially. Connexivum with basal half of each segment yellowish. Male genitalia (Figs. 41–46): medial process of pygophore long, curved, with an acute apex; when “in situ,” only the paramere apices evident (Figs. 41–43). Parameres symmetrical, thin, curved on the apex, with long hairs on internal, apical, and external face, with elongate apical teeth with blunt apex; adjoining seta almost as long as apical teeth and with acute apex (Fig. 44). Phallus with articulatory apparatus short; struts fused, enlarged at base; endosome with long and numerous projections (Fig. 45); apical pair more developed and conspicuous (Figs.45– 46).

Remarks. P. z i k a n i sp. nov. can be separated from P. spinosus mainly by the following characters: 1— greater length; 2—clypeal spine absent (Figs. 27–28); 3—absence of spines at the apices of fore and mid femora (Figs. 31–33, 35–36); 4—spines at hind femoral apices smaller (Figs. 13–14, 37–38); 5—distal black spots on femora in a subapical position (Figs. 27, 31–33, 35–38); 6—forewings longer than abdomen; 7— pterostigma with a large reddish spot (Fig. 27, 39); 8—medial process of pygophore more developed and curved (Figs. 19–21, 41–43); 9—parameres thinner in basal portion, and more curved in apical portion (Figs. 22, 44); 10—apical tooth of paramere thinner and straighter (Figs. 22, 44); 11—adjoining seta of apical tooth of paramere much more developed, almost of the same dimensions as the apical tooth (Figs. 22, 44); 12— endosome with much longer spinelike projections, including a more developed apical pair (Figs. 23–24, 45– 46).

Etymology. The new species is named for the late Mr. José Francisco Zikán (1881–1949), an amateur entomologist whose huge collections of insects have helped generations of entomologists in Brazil.
