Etymology

The species name used in apposition is the contraction of “la princesse”, the original name of “Sleeping Beauty” in the classic 1697 fairytale by Charles Perrault. The name refers to the fact that the single known female has been sleeping in the collections of the MNHN for more than one century.

INDONESIA: 1 ♀: [Museum Paris, Sumatra, Benkollen, Marang-Liwa, Coll. Noualhier 1898] [Museum Paris, MNHN ( EH), 22030] ( Fig. 24 ). Coordinates of Marang-Liwa : 5°04’S 104°06’E ( Medler 1999).

Description

MEASUREMENTS AND RATIOS. TL: 31.6mm; LTg/BTg = 2.08; BV/LV = 3.12; LF/BF = 1.11.

HEAD ( Figs 22–23, 25 ). Entirely orange. Elongate with scimitar-shaped process projecting antero-dorsally and curved backwards apically; apex pointed; process broader than eye in lateral view and about as long as pro- and mesonotum together. Vertex before process broader than long and irregularly wrinkled; posterior and lateral margins carinate; lateral carinae extending to apex of process. Frons elongate with 2 smooth discal carinae extending to apex of process and getting more strongly marked from base to apex. Lateral margins of frons carinate, extending along sides of process and sub-parallel to anterior margin. Clypeus slightly narrower than frons and with sides sub-parallel on basal half. Postclypeus pointed. Labium reaching hind coxae ( Fig. 20 ). Antennae with scape cylindrical and pedicel reniform.

THORAX ( Figs 22–23 ). Orange. Pronotum nearly smooth, with obsolete longitudinal carina and transverse wrinkles; dorso-lateral carinae with edge black-brown. Mesonotum with smooth peridiscal carinae. Longitudinal carina of metathoracic pleura black-brown. Tegulae orange.

TEGMINA ( Figs 19– 21 ). Orange with irregular reddish spots, some of them with orange center. Sutural margin with 7 very small black-brown spots on edge. Costal and apical margins broadly rounded. Ventral surface slightly covered with white wax.

HIND WINGS ( Figs 19–20 ). Broad, orange with rosy-red large basal patch covering about half of total surface. Numerous cross-veinlets marked with milky white and forming dense net on entire wing. Anal area well developed.

LEGS ( Figs 19–20 ). Rosy orange with tarsi I and II yellow-brown. All tibiae slender. Tibiae III with 5 lateral and 7 apical spines.

ABDOMEN ( Figs 19–20 ). Rosy red dorsally, yellow-brown ventrally.

Note

It is possible that the colour of living specimens is more or less olivaceous or green and that it faded to orange after death, as has also been observed in E. brevirostris .

Distribution

Sumatra (see map Fig. 26 ).
