Ichnea divisa (Chevrolat, 1843)

( Figs. 60, 88 , 103 , 114, 115 , 153 , 161 , 183 ; Map 4 )

Enoplium divisa Chevrolat, 1843: 37 . Lectotype ♀. New status. Brazilia (D. Pomponio). (MNHN). (Specimen pin mounted; support card; identification/locality label; specimen number label-377; type label.) Comparisons involving the primary type of I. divisa and of I. opaca lead me to conclude that the two specimens are not conspecific as indicated by Corporaal (1950: 272). Lacordaire 1857: 477; Gemminger and Harold 1869: 1751; Lohde 1900: 100; Schenkling 1903: 102.

Ichnea enoplioides Spinola, 1844: 25 . Lectotype ♂. Here designated. Cayenne, French Guiana. The binomials Enoplium roseicolle , Enoplium crinipenne , Enoplium nigripenne , and Enoplium lymexylonoides listed as synonyms under this species in Corporaal (1950: 271) are considered nomen nuda. The justification for such an action is discussed by Ekis (1975). Furthermore, the illustration provided by Spinola (1844: Plate 37, Fig. 1 ) and study of the lectotype clearly indicate synonymy with E. divisa , not with E. marginella (Corporaal 1950) and not with I. opaca (Ekis 1975) , as comparisons of types now indicate. Lacordaire 1857:477; Lohde 1900:101; Schenkling 1903: 102; Blackwelder 1945: 389; Corporaal, 1950: 271; Ekis 1975: 49.

Paralectotypes. The original description is based on an unknown number of specimens. Except for the lectotype, no other specimens of this species have been found in the MNHN .

Diagnosis. The roseate pronotum and the more slender body form (compare Figs. 60 and 89) will easily separate the members of this species from superficially similar specimens of I. opaca .

Description. Size: Length 7.1 mm; width 2.4 mm. Form ( Fig. 153 ): Oblong subovoid. Integumental color ( Fig. 60): Cranium yellow brown; pronotum roseate; elytra dark brown; legs mostly brown, distal extremity yellow. Head: HW/PW 0.96; frons indented; EW/VW 1.8; antenna as in Fig. 161 , funicle not compressed. Thorax: Pronotum, PL/PW 1.0; elytra subovoid, EL/PL 4.6; EL/EW 2.3; anterior margin of protibia with 12 spines. Male genitalia: Aedeagus as in Fig. 183 . Male mesodermal internal reproductive organs: As in Fig. 114 ; testis comprised of 22 follicles. Female mesodermal internal reproductive organs: As in Fig. 115 .

Variation. Size: length 6.0– 8.1 mm; width 1.8– 4.6 mm. In some specimens, the femora are mostly yellow. In others, the elytral disc shows a faint, oblique fascia at the middle.

Natural History. Specimens have been collected throughout the year, some at altitudes ranging from 300 to 500 m.

Distribution. The known range of this species extends from central Costa Rica to southern Brazil ( Map 4 ).
