Szeptyckiella lii View in CoL sp. nov.

Types

Holotype. Female on slide, China: Guangdong Province: Nanling National Natural Reserve (altitude 1026 m, 24°55 ʹ 42.6 ʺ N, 113°0 ʹ 58.3 ʺ E,), 22 July 2010, F. Zhang and Z.-H. Li leg. (C9640) GoogleMaps . Paratypes. Two females on slide and two in alcohol, same data as holotype. Holotype and three paratypes (one on slide, two in alcohol) in NAU, one paratype (on slide) in MNHN .

Description

Body length: up to 1.00 mm. Ground colour pale yellow in alcohol ( Figure 7A View Figure 7 ). No eyes. Most scales coarsely striate, and leaf-like with tip pointed ( Figure 7C View Figure 7 ); present on head, tergites and ventral side of manubrium, absent on Ant. I; scales on manubrium narrower ( Figure 7D View Figure 7 ).

Antenna 1.35–1.54 times as long as cephalic diagonal. Antennal segments ratio as I: II: III: IV = 1: 2.11: 1.89: 3.67. Antennal chaetae mainly with seven types similar to above two species; smooth straight mic at base of antennal segments (three dorsal and three ventral on Ant. I, and one internal, one external and one ventral on Ant. II); curved, thin or moderately thick (on Ant. II–IV), blunt S-chaetae (two internal and three external on Ant. II, not clear on Ant. III–IV); swollen S-chaetae absent on Ant. I, and one dorso-distal present on distal Ant. II; dagger-shaped chaetae present on ventral Ant. II–IV, one external on Ant. II and three ventral on Ant. III. Ant. III organ with chaetae 2 and 3 swollen ( Figure 8A View Figure 8 ). Labral margin without papillae. Lateral process of labial palp as thick as normal chaetae, with tip just reaching apex of closest labial papilla ( Figure 8B View Figure 8 ). Labial base as mRel 1 l 2, R ciliate and 0.6 as long as chaeta m; chaetae X 2 and X 3 absent, X and X 4 ciliate; G 1–4 and H 3 smooth ( Figure 8C View Figure 8 ). Cephalic dorsal chaetotaxy with five sutural mac and three mac in Gr. II. Clypeal chaetae ciliate ( Figure 8D View Figure 8 ) .

Abd. IV 3.1–3.6 times as long as Abd. III along dorsal midline. Trochanteral organ with 10–12 smooth spiny chaetae ( Figure 8E View Figure 8 ). Ungual unpaired inner tooth present. Unguiculus outer edge smooth ( Figure 8F View Figure 8 ). Ventral tube anteriorly with five or six small and two large ciliate chaetae on each side; posteriorly with four distal smooth and four proximal chaetae; each lateral flap with six smooth chaetae, and one smooth or weakly ciliate ( Figure 8G View Figure 8 ). Manubrial plaque with two pseudopores and three ciliate chaetae ( Figure 8H View Figure 8 ). Distal smooth part of dens 2.4 times as long as mucro ( Figure 7B View Figure 7 ).

Chaetotaxy. Th. II with three medio-medial (m1, m2, m2i), three medio-lateral (m4, m4i, m4p), 23–24 posterior mac and three lateral S-chaetae ( Figure 7E View Figure 7 ); mac p4i rarely present. Th. III with 25 macrochaetae and two lateral S-chaetae ( Figure 9A View Figure 9 ). Abd. I with four mac (m2–4, m4p) and two lateral S-chaetae. Abd. II with four central (a2, m3, m3e, m3ep), one lateral (m5) mac and two S-chaetae. Abd. III with one central (m3), two lateral (am6, pm6) mac and three S-chaetae ( Figure 9B View Figure 9 ). Abd. IV with four central and five lateral (F1, E2–4, E2p) mac ( Figure 9C View Figure 9 ); S-chaetae not clearly seen. Abd. V with three S-chaetae (as, acc.p4, 5, Figure 9D View Figure 9 ). Accessory mic of bothriotricha on Abd. II–IV scaly.

Ecology

In litter of forest.

Etymology

Named after the collector Zhao-Hui Li.

Remarks

This new species differs from other species of Szeptyckiella in having ciliate R and H 1, 2 and 4 on ventral side of head, smooth outer unguiculus edge and abundant tergal chaetotaxy ( Table 1). The arrangement of S-chaetae on Abd. V is similar to that of most entomobryids.
