Geographical Distribution. Colombia, Ecuador.

Female. It differs from male as follows: antennae 1.3 times body length, reaching elytral apex at about midlength of antennomere VIII; antennal formula based on length of antennomere III: scape = 0.95; pedicel = 0.11; IV= 0.82; V= 0.62; VI = 0.57; VII = 0.53; VIII = 0.52; IX= 0.52; X= 0.51; XI = 0.39. Apex of abdominal ventrite V emarginate.

Remarks. Monné (2009) proposed Parabaryssinus for P. lineaticollis (Gounelle, 1910) previously allocated in Baryssinus Bates, 1864. The genus is characterized especially by the prothorax with median lateral tubercle; sides anterior and posterior to the tubercle subparallel and by the elytra with remarkable dorsal and lateral carinae (Monné 2009).

Although the prothorax sides have been mentioned as a diagnostic feature, the prothorax is clearly widened posteriorly, toward the tubercle, similar in some species of Baryssinus and Neobaryssinus Monné & Martins 1976. In transferring the name, Monné (2009) referred P. lineaticollis to the figure 6 (p. 325) of his work. However, the figure 6 corresponds to Tropidocoleus bicarinatus Monné, 2009, described in the same work. Through photographs of the holotype of P. lineaticollis (Figs 16–19) it was possible to confirm that the true P. lineaticollis corresponds to the figures 1–2 (p. 323). Monné (2009) reported the specimen of P. lineaticollis illustrated by him (p. 323) as a male. However, apparently it is a female, since the length of the antennomeres differs from the holotype (male) and corresponds to the female examined by us (Figs 20–22). Additionally it was possible to verify variation in the postmedial dorsal spots of the elytra, which may or may not be interspersed posteriorly by yellowish pubescence (Figs 16, 20).
