Pieza parakake Mendes, Lamas, Evenhuis   & Limeira-de-Oliveira, sp. nov.

( Figs 27–34 View FIGURES 27–34 )

Diagnosis. Mesonotum pale yellow to yellow on the submedian antero-mesonotal triangular mark, submedian stripe projecting from antero-mesonotal triangular mark to prescutellar region (broadly connected posteriorly), and supra-alar area ( Fig. 28 View FIGURES 27–34 ). Gonocoxite with anterodorsal margin strongly concave, anteroventral margin with rounded bulge, setose, slightly depressed medially in anteroventral view ( Fig. 33 View FIGURES 27–34 ). Gonostylus trifurcate, small projections convergent in ventral view ( Fig. 31 View FIGURES 27–34 ).

Ocellar triangle light brown. Frons dorsal ¼ light brown, ventral ¾ yellow, brown medially on median depression; setae brown, small, lateral; face yellow. Proboscis dark yellow to light brown, almost same length as head; oral cavity yellow, light brown marginally. Postcranium brown to light brown, yellow band along posterior eye margin; setae brown. Antenna with second flagellomere subequal in length to first flagellomere. Thorax. Mesonotum with setae brown, proclinate and reclinate, sparse; mesonotum pale yellow to yellow on the submedian antero-mesonotal triangular mark, submedian stripe projecting from antero-mesonotal triangular mark to prescutellar region (broadly connected posteriorly), and supra-alar area ( Fig. 28 View FIGURES 27–34 ); prealar and notopleural setae lost. Scutellum dark yellow to light brown; setae brown, sparse. Pleura yellow on the proepimeron, dorsal and posterior margins of anepisternum, dorsal ¼ of katepisternum, posterior margin of anepimeron and about dorsal ½ of meron ( Fig. 29 View FIGURES 27–34 ); setae brown, sparse, restricted to margin of anepisternum. Legs ( Fig. 27 View FIGURES 27–34 ). Mid- and hindlegs lost. Coxae dark yellow to light brown. Femora dark yellow to light brown; distal ⅓ yellow. Tarsi yellow, tarsomeres II−V dark brown. Wing ( Fig. 30 View FIGURES 27–34 ). Infuscated dark yellow, except on cell r 1, light brown; costal vein ending at ½ distance between veins R 4+5 and M 1; vein R 2+3 arising from Rs at approximately 60° angle, crossvein m-m almost same length as crossvein r-m. Halter yellow, infuscated brown. Abdomen. Dark yellow to light brown, subshiny; tergites II−VII with plaques paler and shinier than surroundings, small, glabrous and dispersed; setae brown, uniform in length; tergites without yellow band on posterior margins. Sternites light brown, without yellow band on posterior margins. Terminalia. Epandrium bulging in ventral view ( Fig. 31 View FIGURES 27–34 ); subrectangular, ventral margin about 1.5X longer than dorsal margin, anterior margin straight; epandrium setose on posterior ⅔ in lateral view ( Fig. 32 View FIGURES 27–34 ); epandrium with outer and inner margins oval in posterior view ( Fig. 34 View FIGURES 27–34 ). Pseudo-surstylus pointed in ventral and posterior views ( Figs 31, 34 View FIGURES 27–34 ). Cercus triangular, sclerotized, setae concentrated on ⅔ of inner surface in posterior view ( Fig. 34 View FIGURES 27–34 ), projecting posteriorly ( Fig. 32 View FIGURES 27–34 ). Ejaculatory apodeme about ¾ length of anterior arm of parameral sheath, more heavily sclerotized on longitudinal axis; medial arms subquadrate, tapering proximally, with posterior margin rounded, almost as wide as long in ventral view ( Fig. 31 View FIGURES 27–34 ), anterior end oval, curved dorsally, ventromedial projection subquadrate, directed posteriorly, apex truncate in lateral view ( Fig. 32 View FIGURES 27–34 ). Lateral ejaculatory process strongly sclerotized basally, slightly sinuous in ventral view ( Fig. 31 View FIGURES 27–34 ), curved ventrally in lateral view ( Fig. 32 View FIGURES 27–34 ). Phallus funnel-shaped, anterior margin flat with median notch small in ventral view ( Fig. 31 View FIGURES 27–34 ); basiphallus about 2.0X longer than distiphallus in ventral view ( Fig. 31 View FIGURES 27–34 ), distiphallus simple with only one apical opening. Anterior arm of parameral sheath with distal ½ almost 3.0X wider than proximal ½ in ventral view ( Fig. 31 View FIGURES 27–34 ), more sclerotized on inner margin. Gonocoxite subquadrate, strongly sclerotized on anterior ½, anterior margin straight, posterior margin rounded, concave medially, setae small on posterior median ⅓ and anteromedian protu- berance in ventral view ( Fig. 31 View FIGURES 27–34 ); gonocoxite with anterodorsal margin strongly concave, anteroventral margin with rounded protuberance, setose, slightly depressed medially in anteroventral view ( Fig. 33 View FIGURES 27–34 ), anteroventral protuberance strongly produced ventrally in lateral view ( Fig. 32 View FIGURES 27–34 ). Gonostylus trifurcate, projections convergent in ventral view ( Fig. 31 View FIGURES 27–34 ). Female. Unknown.

Etymology. To highlight the proximity of this species to P. kake   , the Greek prefix para (= “near”) was added to the epithet kake   .

Comments. It was not possible to ascertain the presence and intensity of pruinosity (except for the abdomen), because the specimens were preserved in alcohol. Pieza parakake   sp. nov. is similar to P. kake   , but since there is no description of the male and female terminalia of the latter, it is difficult to compare the two species. The specimens captured directly from flowers, in Parque Nacional Serra das Confusões—Piauí, are associated with plants of the family Malvaceae   (Figs 72–73), and those captured in Riacho do Ouro, rural area of the municipality of Caxias— Maranhão, are associated with plants of the family Rubiaceae   (Fig. 71). The terminalia of the paratype is lost.

PARATYPE: MA[= Maranhão], Caxias, Zona Rural, Riacho do Ouro , 04°48′11″S, 43°20′30″W / Varredura , 24.vii.2012, JAR, FLO GoogleMaps   & J.S. Pinto Júnior (pinned: 1♂ CZMA)   .

Geographical record. This species is known only in the Brazilian states of Maranhão and Piauí ( Fig. 69 View FIGURE 69 ), where the type series was collected in the Cerrado and Caatinga biomes.

Remarks. Pieza parakake   sp. nov. is similar to P. bittencourti   sp. nov. in having gonostyli trifurcate in ventral view ( Figs 22 View FIGURES 18–26 , 31 View FIGURES 27–34 ). Pieza parakake   sp. nov. differs from P. bittencourti   sp. nov. in the ejaculatory apodeme with the ventro-medial projection subquadrate in lateral view ( Fig. 32 View FIGURES 27–34 ) (ejaculatory apodeme with ventro-medial projection sub-oval in P. bittencourti   sp. nov. in lateral view, Fig. 23 View FIGURES 18–26 ); gonocoxites with anteroventral margin protuberant in anteroventral view ( Fig. 33 View FIGURES 27–34 ) (gonocoxites with anteroventral margin not protuberant in P. bittencourti   sp. nov. in anteroventral view, Fig. 24 View FIGURES 18–26 ). Pieza parakake   sp. nov. is similar to P. kake   in having the thorax with a submedian stripe projecting from the antero-mesonotal triangular mark to the prescutellar region ( Fig. 28 View FIGURES 27–34 ) and cell r 1 infuscated yellow to light brown. Pieza parakake   sp. nov. differs from P. kake   in the dark to dark brown mesopleura with yellow areas on the proepimeron, anepisternum, katepisternum and meron ( Fig. 29 View FIGURES 27–34 ) (mesopleura entirely brown in P. kake   ).
