Euphaedra eberti eberti Aurivillius, 1898

Description of males.

Wingspan: 6.0-7.2 cm (n = 16, x- = 6.51 cm, SD = 0.31). The dorsal side appears metallic green (Figure 1a ). Subapical band in clearly “S” shape (Figure 1b ), pale green or yellow green (never white). Ventral side is generally brown with green, ochre or orange shades. A basal reddish area is nearly always observed in the FWV cell and space 8 of HWV (Figure 1c ), the pale yellow subapical band of FWV being also “S” shaped (Figure 1d ). The HWV submarginal band is well developed and clearly visible (Figure 1e ). The inner part of the space 6 of the HWV is always darker (gray green) than the outer side (creamy yellow) (Figure 1f ). The cells 3-5 are similarly divided into the two colored parts (inner darker and outer lighter) (Figure 1g ). Spots in discal cell on HWV are scarce, only 1 or 2 (rarely 3) are present (Figure 1h ).

Male genitalia (Figure 6a, b ). The E. eberti eberti male genitalia copy the pattern for the genus Euphaedra , e.g., E. eshu , E. wojtusiaki , resp. E. cyparissa and E. sarcoptera ( Pyrcz et al. 2011, 2013). Tegumen has the same length as uncus that is wide on base, slightly arched in distal third, with a sharp tip pointing to valvae in lateral view. Gnathos is straight and long, about the same length as uncus, saccus narrowed and with a spiny tip, slightly curved in lateral view. Valvae with simple sacculus in the middle of the valvae are smooth, oblong, slightly narrowing to the distal end, which is simple and round. At the distal end of aedeagus is a tip with semi-circularly arranged short cornuti on its base.

Description of females.

Wingspan: 7.6-9.0 (n = 16, x- = 8.19 cm, SD = 0.33). FWD dorsal ground color black with a gray-blue-green (Figure 2a ) basal area covering spaces 1a, 1b and basal portion of space 2; white (never yellow) subapical band, “S” shaped and highly variable in size (Figure 2b ). Ventral side generally brown with green, ochre or orange shades. A bit red almost always on the basal cells of both wings (Figure 2c ). Subapical band on FWV in “S” shape (Figure 2d ), pale yellow. HWV with submarginal spots forming clearly visible band (Figure 2e ). Females show the same characteristic mark observed in males - darker inner part and lighter other side of the space 6 (Figure 2f ). The spaces 3-5 show the same characteristics - inner part darker (gray-green) and outer one lighter (creamy yellow) (Figure 2g ). Spots in HWV discal cell weak, in most cases being present only 1 or 2 (rarely 3) (Figure 2h ).

Female genitalia (Figure 6c ). Papillae anales are long and narrow, ductus bursae as long as corpus bursae oval shaped. Corpus bursae, which is longitudinally finely curled, no signum. Bursa copulatrix is broad, apophyses posteriores shorter than papili annales and extended antrum sclerotized.
