Ichnea mimica Gorham, 1877: 412 . Lectotype ♂. Herein designated. Amazon , Para (Bates) (BMNH). (Specimen point mounted, gender label affixed to paper point; support card; locality label; round type label, rectangular type label; specimen number label; Gorham type label; Fry collection label; identification locality label; lectotype label; plastic vial with aedeagus.) Lohde 1900: 101; Schenkling 1903: 102, 1910: 123; Blackwelder 1945: 389; Corporaal 1950: 272.

Diagnosis. The strong constriction of the anterior half of the pronotum and the postmedial yellow elytral fascia will conveniently distinguish the members of this species from specimens of I. lycoides , the only other known species of Ichnea that exceeds 10 mm.

Description. Size: Length 12.0 mm; width 3.5 mm. Form ( Fig. 133 View Fig ): Narrowly triangular. Integumental color ( Figs. 106 View Figs , 133 View Fig ): Cranium mostly dark brown, epicranium narrowly yellow behind eyes, pronotum mostly dark brown, yellow at upper sides; elytra mostly dark brown, with short yellow line at humeral angles and broad yellow fascia behind middle. Head: HW/PW 1; frons indented; EW/VW 4.9; antenna as in Fig. 169 View Figs , funicle not compressed. Thorax: Pronotum considrably narrowed in anterior half; PL/PW 1; strongly flared to posterior two-thirds, EL/PL 5.4; EL/ EW 2.1; anterior margin of protibia with 13 spines.

Variation. Size: length 13.0– 13.5 mm; width 5.0– 5.2 mm. Other than small differences in size, the available specimens do not vary appreciably.

Distribution. Known only from Brazil ( Map 5 View Map 5 ).

Specimens Examined. In addition to the lectotype, I have examined two specimens from BRAZIL: Amapá: Pará. Specimens are deposited in CMNH and WOPC .
