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 ).

Material examined. Ecuador, Napo (Sierra Azul, Valle Hermoso , 2200m, 0º40’S, 77º 55”W), 1 female, 26.I.1996, T. Erwin et al. Col. ( MZSP) ; Cosanga , 2100m, 2015-VII-27 J. 1 male, McClarin Leg. ( QCAZ) .
