Pyrochlora majorcula Dyar, 1925: 7   . Type locality: French Guiana: Cayenne.

Measurements: Wing span 25.0–28.0 mm in males (n= 21), 33.0 mm in females (n= 2). Length of antennal pectinations in males 0.51–0.52 mm (n= 10) (Form A), or 0.52–0.56 mm (n= 5) (Form B), 0.45 mm in female.

Description: The species is characterized by the sack-shaped aedeagus similar to but longer than that of P. rhanis   , with a short apical spine; sternite A 8 sclerotized and distally straight-edged, not emarginated posteriorly. There are differences between the populations from Kaw Mts. and NE Brazil (male antennae shorter pectinated; the dorsobasal appendix from valve costa pollex-like, straight, and valve ventral margin less angulate at its basal third; Fig. 25 View FIGURES 22 – 30 ), and from Ecuador (antennal pectinations longer; the costobasal appendix of valve rounded and valve ventral margin angulate at sacculus: Fig. 28 View FIGURES 22 – 30 ). The entire male armature is relatively more massive in moths from Ecuador and thinner in the Fr. Guyana population ( Figs. 25–30 View FIGURES 22 – 30 ). Moths from SE Brazil differ in wings shape, relatively shorter and broader, sharing genital characters of the Form A (except a slightly more slender saccus).

Biology: Confined to tropical rain forests on lowland and low mountains.

Distribution: Fr. Guiana, N. Brazil, Ecuador ( IZBE, ZSM, CAL, CAS).

Remarks: The specimens in the British Museum collection were identified by Prout (1932) and recently rechecked by Pitkin (1996). The type specimen no. 27500 was selected and designated as lectotype for Pyrochlora majorcula Dyar   by L. Pitkin in the collection of Smithsonian Institution, Washington, USA. ( Fig. 1 View FIGURE 1 ).
