- Szeptyckiella boulouparica sp. nov. 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 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). No eyes. Body scales coarsely striate, leaf-like with tip pointed (Figures 1D, 2P); present on Ant. I, head, tergites and ventral side of manubrium; scales of manubrium narrower (Figures 1F, 2Q). 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, A 1) or blunt (few on Ant. II, Figure 2, A2); (2) smooth straight mic at base of antennal segments (Figure 2, A 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, A 4); (4) curved, subcylindrical, thin (on Ant. II–IV, Figure 2, A 5) or thick (on Ant. IV, Figure 2, A 6), blunt S-chaetae (Figure 1B); (5) short, ordinary or thin S-chaetae on Ant. I– IV (Figure 2, A 7); (6) swollen S-chaetae (Figure 2, A 8) absent on Ant. I, and 1 dorsodistal on Ant. II; (7) short dagger-shaped chaetae ventrally on Ant. II–IV (Figure 2, A 9). Ant. III organ with chaetae 2 and 3 swollen, chaeta 5 shorter than chaeta 4; chaeta 6 absent (Figures 1C, 2B). Labral margin with two strong conical papillae. Prelabral and labral chaetae 4/5, 5, 4, all smooth (Figure 2C). Lateral process of labial palp as thick as normal chaetae, with tip just reaching apex of closest labial papilla (Figure 2D). Maxillary outer lobe shown in Figure 2E. 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). Cephalic dorsal chaetotaxy with four sutural mac and one mac in Gr. II (Figure 2G). 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). Inner outstanding mac located at about 0.4 distance from base, ciliate, thick and tapered (Figure 2I). Ungual unpaired inner tooth extremely tiny. Unguiculus with a large outer tooth (Figure 2J). Ventral tube anteriorly with one small and one large ciliate chaeta on each side (Figure 2K); posteriorly with four apical smooth and two weakly ciliate proximal chaetae (Figure 2L); each lateral flap with four smooth chaetae (Figure 2M). Manubrial plaque with one pseudopore and two ciliate chaetae (Figure 2N). Distal smooth part of dens 1.7 times as long as mucro (Figure 2O). 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). 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). Abd. IV with four central, five lateral (F1a, F1, E2, E3, D3) mac, six short and at least 10 long S-chaetae (Figure 3B). Abd. V with four S-chaetae (as, acc.p3, 4, 5); m2, m3 and m5 mac always much larger than others (Figure 3C). Accessory mic of bothriotricha on Abd. II–III strongly modified; those on Abd. IV nearly as normal chaetae (Figure 1E). 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.
