Pilosirus versus OPITZ, nov.sp.

(Figs. 86, 142, 162, 175)

Holotype: ♀. Serra de Baturite, Ceara (Brazil), Gounelle, 1. 1895 (MNHN).

Diagnosis: Distinguishable from superficially similar specimens of Pilosirus amazonicus by having much narrower flavotestaceous lines on the pronotal disc. Also, the pronotal tubercle is more acute than it is in amazonicus specimens (compare Figs. 141, 142).

Description: Size: Length 7.0 mm; width 2.0 mm. Form: As in Fig. 162. Color: Cranium mostly black, clypeus and cranial venter flavotestaceous; pronotum mostly black, upper sides narrowly flavotestaceous; mesoscutellum black; elytra black. Head: Antennal capitulum long (Fig. 86), each capitular antennomere not as long as combined length of funicular antennomeres; antennal carina very prominent; EW/FW 12/15. Thorax: Pronotal anterior margin not projected at middle, side margin of disc with subacute tubercle; PW/PL 45/45; elytral disc not strongly deflexed at sides, carina not present; EL/EW 160/30. Abdomen: Female pygidium not incised at distal margin.

Distribution (Fig. 175): Known only from the type locality.

Etymology: The trivial name, versus (= line), is a Latin noun. I refer to the narrow flavotestaceous line on the pronotal disc.
