Types

Holotype. Female on slide: New Caledonia: Province Sud: Bouloupari: Mont Do , soil under Araucaria, Berlese extraction, 12 December 1995, L. Deharveng and A. Bedos leg. (NC95-206) . Paratypes. Two probably females on slide, same data as holotype (NC95-206); two females on slide, ibid, Araucaria litter (NC95-205). Holotype and two paratypes in MNHN ( NC95-205 About MNHN and NC95-206), two paratypes in NAU (NC95-205 and NC95-206) .

Description

Body length up to 1.00 mm, male smaller than female. Ground colour pale yellow in alcohol ( Figure 1A View Figure 1 ). No eyes. Body scales coarsely striate, leaf-like with tip pointed ( Figures 1D View Figure 1 , 2P View Figure 2 ); present on Ant. I, head, tergites and ventral side of manubrium; scales of manubrium narrower ( Figures 1F View Figure 1 , 2Q View Figure 2 ).

Antenna about 1.7–1.9 times as long as cephalic diagonal. Antennal segments ratio as I: II: III: IV = 1: 1.73–1.83: 1.40–1.67: 2.91–3.40. Antennal chaetae with seven main types: (1) ciliate, long or short; apically pointed ( Figure 2 View Figure 2 , A 1 View Figure 1 ) or blunt (few on Ant. II, Figure 2, A2 View Figure 2 ); (2) smooth straight mic at base of antennal segments ( Figure 2 View Figure 2 , A 3 View Figure 3 ), three dorsal, three ventral and one external on Ant. I and one internal, one external and one ventral on Ant. II; (3) numerous short smooth straight chaetae present on Ant. IV laterally ( Figure 2 View Figure 2 , A 4 View Figure 4 ); (4) curved, subcylindrical, thin (on Ant. II–IV, Figure 2 View Figure 2 , A 5 View Figure 5 ) or thick (on Ant. IV, Figure 2 View Figure 2 , A 6 View Figure 6 ), blunt S-chaetae ( Figure 1B View Figure 1 ); (5) short, ordinary or thin S-chaetae on Ant. I– IV ( Figure 2 View Figure 2 , A 7 View Figure 7 ); (6) swollen S-chaetae ( Figure 2 View Figure 2 , A 8 View Figure 8 ) absent on Ant. I, and 1 dorsodistal on Ant. II; (7) short dagger-shaped chaetae ventrally on Ant. II–IV ( Figure 2 View Figure 2 , A 9 View Figure 9 ). Ant. III organ with chaetae 2 and 3 swollen, chaeta 5 shorter than chaeta 4; chaeta 6 absent ( Figures 1C View Figure 1 , 2B View Figure 2 ). Labral margin with two strong conical papillae. Prelabral and labral chaetae 4/5, 5, 4, all smooth ( Figure 2C View Figure 2 ). Lateral process of labial palp as thick as normal chaetae, with tip just reaching apex of closest labial papilla ( Figure 2D View Figure 2 ). Maxillary outer lobe shown in Figure 2E View Figure 2 . Labial base as mrel 1 l 2, all smooth; r 0.6 as long as chaeta m; chaetae X 2 and X 3 absent, X 4 ciliate; smooth chaeta X rarely present ( Figure 2F View Figure 2 ). Cephalic dorsal chaetotaxy with four sutural mac and one mac in Gr. II ( Figure 2G View Figure 2 ). Clypeal chaetae smooth .

Abd. IV 2.3–3.5 times as long as Abd. III along dorsal midline. Trochanteral organ with eight or nine smooth spiny chaetae ( Figure 2H View Figure 2 ). Inner outstanding mac located at about 0.4 distance from base, ciliate, thick and tapered ( Figure 2I View Figure 2 ). Ungual unpaired inner tooth extremely tiny. Unguiculus with a large outer tooth ( Figure 2J View Figure 2 ). Ventral tube anteriorly with one small and one large ciliate chaeta on each side ( Figure 2K View Figure 2 ); posteriorly with four apical smooth and two weakly ciliate proximal chaetae ( Figure 2L View Figure 2 ); each lateral flap with four smooth chaetae ( Figure 2M View Figure 2 ). Manubrial plaque with one pseudopore and two ciliate chaetae ( Figure 2N View Figure 2 ). Distal smooth part of dens 1.7 times as long as mucro ( Figure 2O View Figure 2 ). Male genital plate papillate and details not seen clearly.

Chaetotaxy. Th. II with two medio-medial (m1, m1i), one medio-lateral (m4), 10 posterior mac and three lateral S-chaetae. Th. III with 10 mac and two lateral S-chaetae; a6, m6, m6e as mac ( Figure 2R View Figure 2 ). Abd. I with one mac (m4) and one lateral S-chaeta. Abd. II with two central (m3, m3e), one lateral (m5) mac and two S-chaetae. Abd. III with one central (m3), two lateral (pm6, p6) mac and three S-chaetae ( Figure 3A View Figure 3 ). Abd. IV with four central, five lateral (F1a, F1, E2, E3, D3) mac, six short and at least 10 long S-chaetae ( Figure 3B View Figure 3 ). Abd. V with four S-chaetae (as, acc.p3, 4, 5); m2, m3 and m5 mac always much larger than others ( Figure 3C View Figure 3 ). Accessory mic of bothriotricha on Abd. II–III strongly modified; those on Abd. IV nearly as normal chaetae ( Figure 1E View Figure 1 ).

Ecology

In litter and soil of a stand of Araucaria , in a thalweg.

Etymology

Named after the type locality.

Remarks

This species is characterized by relatively short antennae (less than twice as long as head), absence of X 2 on ventral side of head, four cephalic sutural mac, modified accessory mic of bothriotricha, reduced number of mac on Th. II, one mac (m4) and one S-chaeta on Abd. I, six short S-chaetae on Abd. IV, and four S-chaetae on Abd. V. Differences with other species of the genus are summarized in Table 1.
