Collaria guaraniana Carvalho & Fontes, 1981 View in CoL

( Figs. 4 View FIGURES 1 – 8 , 27 View FIGURES 25 – 37 , 40 View FIGURES 38 – 50 , 84 View FIGURES 82 – 93 , 96 View FIGURES 94 – 105 )

Collaria guaraniana Carvalho & Fontes, 1981: 16 View in CoL , [n.sp.]; Schwartz 2008: 1179 [diag., morph.]; Schuh 2002–2014 [catalog].

Diagnosis. Distinguished from cogeners by the head with a black bifurcate (Y-shaped) spot on frons ( Fig. 4 View FIGURES 1 – 8 ), hemelytra with a dark spot on clavus and irregular dark patches on corium ( Fig. 4 View FIGURES 1 – 8 ); endosoma with large sclerite extending distad to the dorsal margin of the secondary gonopore ( Fig. 40 View FIGURES 38 – 50 ) and long sclerite strongly tapered towards apex ( Fig. 40 View FIGURES 38 – 50 ).

Redescription. Male. COLORATION: Brown with pale-yellow and black areas. Head: Brown with Y-shaped black mark extending from longitudinal sulcus to frons, a black transversal line between eyes and two black spots on neck; eye dark brown; mandibular plate, maxillary plate, and apex of buccula, black; labium brown with black apex; clypeus with a black longitudinal spot; antennal segments brownish, segment I pale brown. Thorax: Pronotum brown, calli and anterior lateral margins of pronotum, black; inner region of calli, pale brown and two rounded black spots on humeral angles; collar pale; proepisternum black, with pale line in margin; scutellum brown with a longitudinal pale yellow. Hemelytra dark-brown with a dark spot on clavus and irregular dark patches on corium; median region of embolium and external region of cuneus, pale; internal and median margin of cuneus and hemelytral membrane, brownish; ostiolar peritreme with pale brown margins; abdomen with brown median spots and a black spot at apex of pygophore. VESTITURE AND STRUCTURE: Head: Antenna pilose; segment I (Table 1), twice width of II; segment II, 3 times longer than I (Table 1). Pronotum: Anterior lobe abruptly narrowed ( Fig. 4 View FIGURES 1 – 8 ), with golden pilosity, long, sparse and erect. MEASUREMENTS: See Table 1. GENITALIA: Parameres: Left paramere sickle-shape with dorsal and ventral margins of basal sensory lobe almost straight, right paramere with basal sensory lobe bulbous and apex of hypophysis, small ( Fig. 27 View FIGURES 25 – 37 ). Endosoma: With large sclerite on secondary gonopore ( Fig. 40 View FIGURES 38 – 50 ); ribbon like sclerite with short lobe or area beneath secondary gonopore covered with microtrichia ( Fig. 40 View FIGURES 38 – 50 ), long sclerite strongly tapered towards apex with an area with microtrichia on basal region ( Fig. 40 View FIGURES 38 – 50 ).

Female: Similar to male in color and size. MEASUREMENTS: Table 1. GENITALIA: Dorsal labiate plate as in Fig. 84 View FIGURES 82 – 93 . Posterior wall with triangular interramal lobes ( Fig. 96 View FIGURES 94 – 105 ). Dorsal structure, covering half of medial process ( Fig. 96 View FIGURES 94 – 105 ). Medial process strongly sclerotized and shaped as an inverted Y ( Fig. 96 View FIGURES 94 – 105 ).

Geographic distribution. Collaria guaraniana was described from southern Brazil ( Carvalho & Fontes 1981).

Plant associations. Grasses, without specific data ( Carvalho & Fontes 1981).

Discussion. Collaria guaraniana is similar to C. capixaba in general coloration, antennal and leg pubescence, but C. guaraniana is longer than C. capixaba , the endosoma has a long sclerite with spicules below one third of the bulbous region and female with posterior wall with sub quadrate interramal lobes and medial process shaped as an inverted Y.

Collaria guaraniana is known only from the type series. These specimens lack precise locality data. For this reason, more fieldwork in search for this species is necessary to produce larger series with accurate host-plant data.

Examined material. Type material: Holotype: 1 ³ BRAZIL: Paraná, 1950, Staurinauski ( MNRJ). Paratypes: 2 ³ 1 ♀, BRAZIL: Paraná, 1950, Staurinauski ( MNRJ).
