Isoforma goryi (LAPORTE)

( Figs 16-23, 27-30 , 71 , 156 , 175 )

Enoplium goryi LAPORTE, 1836: 54 .

Holotype: Gender not known. Cayenne ( French Guiana) ( MIZT).

KLUG 1842: 395 (Enoplium). SPINOLA 1844: 65 ( Platynoptera ). DESMAREST 1852: 270 ( Platynoptera ) SCHENKLING 1906: 311 ( Platynoptera ). CORPORAAL 1950: 273 ( Platynoptera ). EKIS 1975: 52 ( Platynoptera ).

Diagnosis: There are 17 spines on the anterior margin of the protibia; among congeners, only in specimens of this species are there more than ten.

Description: Size: Length 15.0 mm; width 8.0 mm. Form: As in Fig. 156 . Color: Cranium mostly black, with flavotestaceous line behind eyes; pronotum mostly black, upper sides flavotestaceous; elytral disc mostly black, with midelytral flavotestaceous fascia, the humeral angle may be flavotestaceous. Head: Antennal capitulum very long ( Fig. 71 ), each capitular antennomere as long as funicle; antennal carina very prominent; EW/FW 22/35. Thorax: Pronotal anterior margin linear, not projected at middle; side margins of disc rounded at middle; PW/PL 100/80; elytra conspicuously flared; disc with 4 discal carinae; EL/EW 200/140. Abdomen: Female pygidium not incised at distal margin.

Natural history: One specimen was collected in August.

Variation: Size: length 10.0-15.0 mm; width 4.0-8.0 mm. The flavotestaceous macula on the humeral angle varies in expression.

Distribution ( Fig. 175 ): In addition to the type, I examined 2 specimens from: French Guiana, Region de Petit-Saut fleuve Sinnamary, 4.VIII.1994, ex. Larva, G. Tavakilian. Specimens are deposited in MNHN and WOPC.
