Notes. Euphaea hirta was originally described based on male specimens from Lam Dong Prov., Vietnam ( Hämäläinen & Karube 2001), and is characterized by the paraproct being invisible in lateral view (a character unique within the genus) and by the abundant setae on the abdomen (notably on S4–5, S8–10 and cerci) ( Fig. 15c View FIGURE15 ) of the male in comparison to E. guerini ( Fig. 15b View FIGURE15 ) and E. masoni ( Fig. 15d View FIGURE15 ); E. guerini also differs from both hirta and masoni by wholly opaque hind wings ( Fig. 14a–c View FIGURE 14 ). The female of Euphaea hirta has not been reported earlier and is described in this paper for the first time. It can be distinguished from female Euphaea masoni by the lateral corners of posterior lobe of prothorax rounded ( Fig. 18i View FIGURE 18 ), not angular as in E. masoni ( Fig. 18j View FIGURE 18 ). In addition, it has narrow thoracic stripes and reduced abdominal markings compared to Euphaea masoni ( Fig. 16a, c View FIGURE 16 ) and its frons lacks yellowish markings ( Fig. 16b View FIGURE 16 ). Female of Euphaea hirta resembles female E. guerini and E. saola sp. nov., but these two species have narrower yellowish markings on thorax ( Figs 16d–e View FIGURE 16 ), although to some extent these characters are age-dependant and must be treated with care.

Description of female. Head ( Fig. 16a–b View FIGURE 16 ). Anteclypeus, postclypeus, frons, and all upper parts of head are black, but for two oval yellowish spots between the antennae and the lateral ocelli. Genae and area between clypeus and eye border broadly yellow, with a black oval spot inside. Base of mandibles yellow, but anterior margin black. Labrum, with large yellow spot, split almost in two parts, but connected along ventral border. Antennae black.

Thorax ( Fig. 16a View FIGURE 16 ). Prothorax is black with a yellow spot on the propleuron. Anterior lobe is entirely black, the middle lobe is black with a pair of large triangular yellow spots. The posterior lobe is black with a small yellow spot at the center and the lateral corners extensively yellow ( Fig. 18i View FIGURE 18 ). Synthorax black with yellow stripes along sutures as shown in Fig. 16a View FIGURE 16 .

Legs. Entirely black.

Wings. Hyaline with black venation.

Abdomen ( Fig. 16a View FIGURE 16 ). Black with yellow marking laterally as follows: S1 has a broad marking. S2–6 have long and thin stripes becoming indistinct distally on each segment. S7 with small anterolateral spot. S8–10 wholly black. Ovipositor black, shown in Figure 16a View FIGURE 16 .

Measurement (in mm). HW 28; abdomen (incl. appendages) 26.
