Ichnea gregata Opitz , new species

( Figs. 52, 3 , 168 , 186 ; Map 4 )

Holotype. Male. Utcuyacu, Tarma Junín, Peru, III-15-1948. A second label-F. Woytkowski, Coll. - Donor Wm. Procter ( AMNH). (Specimen point mounted, antenna and gender label affixed to paper point; mount card; locality label; collector label; AMNH acronymic label; holotype label; plastic vial with aedeagus.)

Diagnosis. The transverse configuration of the eighth antennomere ( Fig. 168 ) will distinguish the members of this species from congeners.

Description. Size: Length 6.8 mm; width 2.0 mm. Form: Narrowly triangular. Integumental color ( Fig. 52): Cranium light brown at front, epicranium black; pronotum lower sides and middle of disc black, remainder yellow; elytra mostly yellow, with dark markings at sutural margin where dark marking unites with broad, black, oblique fascia, latter narrowly conjoined with narrow dark epipleural line that ends just behind humeral angle. Head: HW/PW 1.0; frons indented; EW/ VW 2.1; antenna as in Fig. 168 , funicle compressed. Thorax: PL/PW 1.3; elytra strongly flared to posterior two-thirds, EL/PL 5.5; EL/EW 2.8; anterior margin of protibia with 9 spines. Male genitalia: Aedeagus as in Fig. 186 .

Natural History. The holotype was collected in March.

Distribution. Known only from the type locality ( Map 4 ).

Etymology. The specific epithet stems from the Latin grego (= assemble) that refers to the compressed nature of the funicle.
