Macrolygistopterus testaceirostris Pic, 1930a: 84 (original description); Kleine, 1933: 104 (catalogue); Blackwelder, 1945: 351 (catalogue); Nascimento, 2013: 324 (checklist of species).

Type material. Macrolygistopterus testaceirostris : syntype, female, São Paulo, Brazil, no other data, hereby designated as lectotype, deposited at MNHN.

Diagnosis. Dorsal rostrum and profemora testaceous, apex of ventrite VII of females acuminated, elytral costa strongly demarcated.

Redescription. Head black, with rostrum dorsally testaceous, as long as antennomeres I+II ( Fig.16 View FIGURES 10 – 18 ); coronal suture shallow, hardly visible; median interocular distance of 2x the width of eyes. Mandibles short, slightly arched, testaceous, connates to labrum. Maxillary palp with palpomere I small, ca. 1/3 the length of II; palpomere II elongate, subconic; palpomeres III+IV as long as II, the last broadened, securiform. Antennae finely pubescent, scape subconic, constrict basally; pedicel small, 1/4 the length of scape; antennomere III as long as the sum of I+II; III to V subequal; antennomeres V to XI gradually decreasing in length.

Pronotum subtrapezoidal, wider than longer (9:12), with margins stout and rounded, angles rounded, testaceous, with a median longitudinal black stripe; a pair of longitudinal elevations parallels, broadened in middle third and less prominent in anterior and posterior region; a pair of oblique elevations in basal third region starting from 3/4 portion and reaching but not touching the broadened region in middle third of pronotum; a pair of curved longitudinal elevations parallel to median longitudinal elevations ( Fig. 26 View FIGURES 19 – 26 ).

Elytra subparallel, broadened apically, with lateral margins stout, testaceous, apical third black, not reticulated. Arrangement of elytral costae: costa I and IV not fused to any other, both free; costae II and III subapically fused, this fusion continuing into a single costa (II+III); elytral costae not reaching elytral apex. Scutellum black, transverse ( Figs. 8 View FIGURES 1 – 9 , 33 View FIGURES 27 – 35 ).

Female ventrite VII transverse, densely pubescent, with apical region deeply notched, forming two acuminated apices ( Fig. 40 View FIGURES 36 – 40 ).

Width at humeri> 3.4 mm. Elytral length— 15 mm.
