1. Protosticta proboscis spec. nov.

( Figs. 1–5 View FIGURE 1 View FIGURE 2 View FIGURE 4 View FIGURE 5 )

Type specimens. Holotype Ƌ: Lagi Coco resort, Bao Loc, Lam Dong Province, southern Vietnam (11.641 N, 107.742 E), 18.V.2016, T. Kompier leg GoogleMaps . Paratype Ƌ same location, date and collector. Both in RMNH GoogleMaps .

Etymology. The specific name proboscis means a long nose and refers to the elongated and drooping shape of the apical lobe of the cerci. It is a noun in apposition.

Description of male holotype. Head. Anteclypeus and labrum bluish white with lower margin of labrum black. Genae bluish white adjacent to labrum, laterally black. Antennae blackish brown, first and second segments pale yellow; postclypeus, frons, vertex and occiput entirely black. Prothorax ( Fig. 1 View FIGURE 1 ). Pale yellow, but posterior lobe black. Synthorax ( Fig. 1 View FIGURE 1 ). Mesepisternum and mesepimeron black with greenish shine. Mesinfraepisternum almost completely black, but small pale yellow marking adjacent to coxae. Metepisternum and metepimeron pale yellow with broad black stripe over metapleural suture continuing over metinfraepisternum. Legs pale yellow with black stripe over flexor surface; spines and claws brown. Wings. Hyaline, 13 postnodal crossveins in forewing, 12 in hindwing. Pterostigma dark brown, covering one cell. Abdomen. Colored as follows: S1–2 dark brown dorsally and pale yellow ventrally; S3–7 dark brown with pale yellow anterior apical ring, pale yellow posterior subapical ring and posterior blackish-brown apical ring; S8 blackish brown with pale yellow ventral mark anteriorly; S9 almost entirely white; S10 blackish brown. Anal appendages ( Figs. 2 View FIGURE 2 –3) black; cerci first upcurved, then strongly curved downward from two-fifths, lacking dorsal tooth in lateral view, the curvature smooth; on the downward trajectory the lateral ridge continues to become the apical lobe, which is long and droops. Paraprocts with elongated tip, tapering, the distal part hollowed out to form a cup without a spine at its distal margin.

Measurements (mm). Hind wing 21; abdomen including appendages 36. Variation in paratype. Abdomen including appendages 35mm. Female. Unknown.

Diagnosis. This species is very similar in general appearance to P. linnaei van Tol, 2008 , and P. socculus Phan & Kompier, 2016 . It shares the same prothorax and synthorax pattern and like these two species has all white S9, but is best identified by the very different shape of the cerci, characterized by the drooping apical lobe.
