description: Macrolygistopterus subparallelus Pic, 1930
(Figs. 7, 15, 25, 32, 45)
Macrolygistopterus subparallelus Pic, 1930a: 84 (original description); Kleine, 1933: 104 (catalogue); Blackwelder, 1945: 351 (catalogue); Costa & Vanin, 2012:55 (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). 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).
Redescription. Head black, prolonged in rostrum as long as sum of antennomeres I+II+III (Fig. 15); 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). Scutellum black, transverse (Figs. 7, 32).
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).
Width at humeri> 2.6mm. Elytral length—10.4mm.
Distribution. Paraguay, only known by the lectotype (Fig. 45).
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.
