Macrolygistopterus subparallelus Pic, 1930a: 84 (original description); Kleine, 1933: 104 (catalogue); Blackwelder, 1945: 351 (catalogue); Costa & Vanin, 2012:55 View Cited Treatment (immature stages).

Type material. Macrolygistopterus subparallelus : syntype, male, Paraguay, no other data, hereby designated as lectotype, deposited at MNHN.

Diagnosis. Pronotum rectangular, with angles slightly directed backwards and strongly sculptured ( Fig. 25 View FIGURES 19 – 26 ). Elytral costa arrangement: costa I and II fused subapically, apex of costa I apically obliterated; costa III subapically obliterated and fused to the outer margin of II; costa IV reaching elytral apex, with an oblique obliterated line linking costa II and IV ( Fig. 32 View FIGURES 27 – 35 ).

Redescription. Head black, prolonged in rostrum as long as sum of antennomeres I+II+III ( Fig. 15 View FIGURES 10 – 18 ); coronal suture reduced, hardly visible. Median interocular distance of 2x width of eye. Mandibles curved, connates to labrum, testaceous. Maxillary palp with palpomere I short; palpomere II twice the length of I; palpomere III slightly shorter than the precedent; palpomere IV securiform. Antennae with scape conic; pedicel 1/3 of scape length; antennomere III subequal to I in length; antennomere IV slightly longer than precedent; antennomeres V to VII gradually shorter.

Pronotum subtrapezoidal, wider than longer (6:9), with anterior margin pronounced, and lateral and posterior margins not pronounced, testaceous, with a wide longitudinal black strip, strongly sculptured; a pair of shallow longitudinal elevations parallels, constricted in 2/5 and 4/5; a pair of oblique elevations starting from close to the anterior angles and reaching but not touching the median enlarged region ( Fig. 25 View FIGURES 19 – 26 ). Scutellum black, transverse ( Figs. 7 View FIGURES 1 – 9 , 32 View FIGURES 27 – 35 ).

Elytra subparallels, lateral margins stout, testaceous with apical third bluish black. Arrangement of elytral costae: Costa I and II fused subapically, apex of costa I apically obliterated; costa III subapically obliterated and fused to outer margin of II; costa IV reaching elytral apex, with an oblique obliterated line linking costa II and IV ( Fig. 32 View FIGURES 27 – 35 ).

Width at humeri> 2.6mm. Elytral length—10.4mm.

Distribution. Paraguay, only known by the lectotype ( Fig. 45 View FIGURES 45 – 46 ).

Examined material. Paraguay, 1 ♂ (lectotype) ( MNHN).

Female unknown.

Comments. Costa & Vanin (2012) described the immatures stages of a Macrolygistopterus species that at the moment of the publication was tentatively identified as M. subparallelus , however, after the comparison of the specimen with the lectotype of M. subparallelus I was able to recognize that the specimen was from another species.
