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 ); 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 ). 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.

Elytral length— 15 mm . Distribution. Brazil , São Paulo, only known by the lectotype ( Fig. 45 ). Examined material . São Paulo, Brasil , 1♀ ( lectotype ) ( MNHN ). Male unknown.
