Zarcosia deharvengi n. sp.

( Figures 1 View FIGURE 1 ; 3f View FIGURE 3 ; 4e View FIGURE 4 ; 5l View FIGURE 5 ; 6e View FIGURE 6 )

Etymology. The species is named after Louis Deharveng in recognition of his efforts to collect material for others.

Type locality. Republic of Indonesia: Sumatera Barat, Baso, Ngalau Simarasop [00°14’ S 100°28’ E] GoogleMaps .

Distribution. Republic of Indonesia: Sumatra ( Figure 1 View FIGURE 1 ).

Description. ( Figure 3f View FIGURE 3 ). Female unknown. Body length. ♂: 2.43± 0.19 mm (n=3). Dark brown, darker anteriorly, gracile, covered with very short, pulverulent pubescence. Appendages orange-brown.

Head. Small, dark, barely wider than pronotum. Palpi yellow, last article securiform. Integument, finely and densely punctuated, grainy, looking like velvet. Occiput lined with a fringe of dense and short silver hairs posteriorly.

Antennae. 1.5 the length of elytra, orange-brown, regularly filiform with antenommeres 3–10 cylindrical.

Pronotum ( Figure 6e View FIGURE 6 ). Round and convex, as long as wide, sides regularly curved. Base sinuated. Surface mat, rugose, covered with dense, velvety pubescence. Punctation undistinguishable.

Elytra. Length: 1.72± 0.13 mm (n=3). Punctation fine and shallow, dense (space between points as wide as the points themselves). Disc depressed. Pubescence dense and short, whitish, comprised of very short hairs borne from the points and interspersed pulverulent hairs.

Legs. Particularly elongated. Foretibia thickened in a smooth tooth on their inner side ( Figure 5l View FIGURE 5 ).

Aedeagus ( Figure 4e View FIGURE 4 ). Sides weakly and progressively convergent in dorsal view, apex rounded. Long, extremely bent in lateral view, apex with a brief downward deflection. Appendages visible near apex.

Type material. Holotype (♂, MNHN). Republic of Indonesia: Sumatra, West Sumatra, Baso, Ngalau Simarasop , (740 m) cave, 00°14’ S 100°28’ E (L. Deharveng & A. Bedos leg.) 10.VII.2000 GoogleMaps . Paratypes. Republic of Indonesia: Sumatra, Aceh, Aceh Besar Regency, Lhok’Nga, P. T. Semen Andalas, 05°27’ N 95°14’ E, Limestone Quarry, Jungle Quarry Cave , 2nd cavern, twilight zone, on sand near guano (I. Davis) 26.VII.1984 (1 ♂ paratype, NGPC) GoogleMaps ; Sumatra, North Sumatra, Penen, Rampah Cave, 1 km E. of Kota Tinggi , 03°19’33” N 98°37’57” E (C. Covill) 26.VII.1984 (1 ♂ paratype, BMNH) GoogleMaps .

Note. The extremely thin and elongated appendages of species likely represent adaptations to life in caves.
