Macrolygistopterus succinctus var. scutellaris Pic, 1930a: 84 . syn. nov.
Type material. Lycus succinctus Latreille, 1811 : male, syntype (labbeled as a female), hereby designated lectotype. " Colombia, Fusagasuga", no other details, deposited at ( MNHN).
Diagnosis. This species can be distinguished from other Macrolygistopterus by having the pronotum subtrapezoidal, black, its disc is glabrous and of shiny aspect, strongly sculptured (some specimens have the pronotum testaceous with a slender black stripe), by elytra testaceous or reddish and by the relatively longer rostrum ( Fig. 10 View FIGURES 10 – 18 ).
Redescription. Head black, with a thin yellow pubescence, with rostrum as long as the sum of antennomeres I+II ( Fig. 10 View FIGURES 10 – 18 ); coronal suture deep; median interocular distance of 3x the width of eyes. Mandibles not curved, with basal portion blackened and apical portion testaceous. Maxillary palp with palpomere I small, about 1/4 the length of II; palpomere II long, as long as sum of III+IV; palpomere IV slighty longer than III, securiform, truncate. Antennae finely pubescent with scape subconic, pedicel with 1/4 the length of scape; antennomere III 1 /4 longer than I+II; antennomere IV subequal to III in length and shape; antennomeres IV to XI gradually decreasing in length.
Pronotum subtrapezoidal, wider than longer (9:11), margins stout, black, with a pair of median elevations, divergent from anterior margin to the middle and converging towards posterior margin, with oblique carinae separating each side of pronotum in two sides ( Fig. 19 View FIGURES 19 – 26 ). If testaceous with a slender black stripe restricted to the region between the median elevations.
Elytra parallel, margins not pronounced, basal third testaceous, some specimens with the inner margins of elytra bluish black, with the rest of elytra bluish black. Arrangement of elytral costae: costa I following alone not touching the apex, obliterated in apical third; costa II and IV subapically fused, forming an arch; costa III fused with the inner margin of the arch formed by costae II+IV, obliterated in the apical half, with transverse lines hardly visible, obliterated ( Figs. 1 View FIGURES 1 – 9 , 27 View FIGURES 27 – 35 ). Scutellum black, transverse.
Female VII ventrite triangularly, as long as wide, apical region of ventrite VII of females notched, forming two acuminated apices ( Fig. 36 View FIGURES 36 – 40 ).
Male genitalia with parameres longer than aedeagus, fused in the basal half; aedeagus with acuminated apex ( Fig. 44 View FIGURES 41 – 44 ). Female genitalia with styli prominent, subapically positioned. Coxites slender, approximated in the apex, with setae in the surface. Valvifers long, 6x longer than coxites ( Fig. 42 View FIGURES 41 – 44 ).
Width (across humerous)—4.2–6.0 mm. Elytral length—13.8–19.8 mm.
Distribution. Colombia, Ecuador, Venezuela and Guatemala ( Fig. 46 View FIGURES 45 – 46 ).

Comments. In 1930a Pic described the variation M. succinctus var. scutelaris , which differs from the M. succinctus only in the coloration of elytra, which is reddish instead of testaceous, and by the bluish-blackened inner elytral margins. Despite color differences, I was not able to find any morphological character to separate the form and the type form and I propose to consider M. succinctus var. scutelaris as a new junior synonym of M. succinctus .
