Szeptyckiella sinelloides View in CoL sp. nov.

Types

Holotype. Female on slide, New Caledonia: Province Sud: Rivière Bleue , 10 December 1995, lowland forest, litter, Berlese extraction, L. Deharveng and A. Bedos leg. (NC95-194) . Paratypes. Three females on slide and eight in alcohol, same data as holotype. Holotype and eight paratypes (two on slide and six in alcohol) in MNHN, three paratypes (one on slide and two in alcohol) in NAU .

Description

Body length 1.42 mm. Ground colour pale yellow in alcohol ( Figure 4A View Figure 4 ). No eyes. Most scales coarsely striate and leaf-like with tip pointed; present on Ant. I, head ( Figure 4D View Figure 4 ), tergites and ventral side of manubrium; scales of manubrium narrower.

Antenna 2.1–2.3 times as long as cephalic diagonal. Antennal segments ratio as I: II: III: IV = 1: 2.44: 2.22: 3.00. Antennal chaetae mainly with seven types similar to S. boulouparica , sp. nov.; smooth straight mic at base of antennal segments, three dorsal ( Figure 4B View Figure 4 ), three ventral and one external on Ant. I and one internal, one external and one ventral on Ant. II; swollen S-chaetae absent on Ant. I, and two dorsal present on Ant. II; dagger-shaped chaetae three, four and at least six ventrally on Ant. II, III and IV respectively. Ant. III organ with chaetae 2 and 3 rod-like and feebly swollen, chaeta 5 shorter than chaeta 4 ( Figure 5A View Figure 5 ). Distal labral papillae absent. Lateral process of labial palp slightly thicker than normal chaetae, with tip reaching beyond apex of closest labial papilla ( Figure 5B View Figure 5 ). Labial base as mrel 1 l 2, all smooth; r 0.65 as long as chaeta m; chaetae X 2 and X 3 absent, X and X 4 ciliate ( Figure 5C View Figure 5 ). Dorsal cephalic chaetotaxy same as S. boulouparica , sp. nov.

Abd. IV 3.6 times as long as Abd. III along dorsal midline. Trochanteral organ with 17 smooth spiny chaetae ( Figure 5D View Figure 5 ). Ungual unpaired inner tooth absent. Unguiculus with a large outer tooth ( Figure 5E View Figure 5 ). Ventral tube anteriorly with two or three small and one large ciliate chaeta on each side ( Figure 5F View Figure 5 ); posteriorly with four distal and four proximal smooth chaetae ( Figure 5G View Figure 5 ); each lateral flap with five smooth chaetae. Manubrial plaque with one or two pseudopores and three ciliate chaetae. Distal smooth part of dens 0.7–1.0 times as long as mucro ( Figure 4C View Figure 4 ).

Chaetotaxy. Th. II with two media-medial (m1, m1i), one medio-lateral (m4), 15 posterior mac and three lateral S-chaetae; p4–6 not mac. Th. III with 17 mac and two lateral S-chaetae; a6, a6i, p6, m6, m6e and m6ai2 as mac ( Figure 5H View Figure 5 ). Abd. I with two mac (m4, m4p) and two lateral S-chaetae. 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 6A View Figure 6 ). Abd. IV with four central, five lateral (F1, E2–3, E2p, D3) mac, four short and about nine long S-chaetae ( Figure 6B View Figure 6 ). Abd.

V with four S-chaetae (as, acc.p3, 4, 5, Figure 6C View Figure 6 ). Accessory mic of bothriotricha on Abd. II–III strongly modified, some scaly; those on Abd. IV nearly as normal mic.

Ecology

In litter of lowland forest on ultramafic rocks.

Etymology

Named after the similarity to species of Sinella .

Remarks

This species differs from S. boulouparica sp. nov. in having longer antennae, no labral papillae, longer lateral process of labial palp, ciliate X on ventral side of head, mac present on a1–3, p1, a6i and p6 on Th. III, m4p and a second S-chaeta on Abd. I, more chaetae on ventral tube and shorter distal smooth part of dens ( Table 1).
