Type material
Holotype: ad. 9 (female), Zijin Mountain , 12 August 2006, leg. H. Shen et al . Paratypes: one ad. 9 (female), Laoshan Mountain , 13 September 2006, leg. H. Shen et al; one ad. 9 (male), Laoshan Mountain, 2 October 2006, leg. H. Shen et al .
Diagnosis
Allopauropus nanjingensis is well-defined in having proportionately long-stalk antennal globulus, an unusual differentiation of the pygidial setae, and in having an unusually large distance between the b 3 and two types of pubescence on the anal plate. Its relationships are impossible to trace at present.
Etymology
A latinization of the name Nanjing, China.
Description
Length. 0.89(–0.95) mm. Head. Tergal setae thin, tapering, of medium length to fairly long, densely annulate. Relative lengths of setae: 1st row: a 1510, a 258; 2nd row: a 1511, a 2520 (–23), a 35 16(–18); 3rd row: a 158, a 2512; 4th row: a 1512, a 25 (16–)18, a 35 (14–)16, a 4517 (–20). Ratio a 1 / a 1 – a 1 in 1st row 1.1, in 2nd row 0.4(–0.5), in 3rd row 0.5(–0.7), in 4th row (0.8–)0.9. Head cuticle glabrous.
Antennae. Segment 4 with four setae, all thin, tapering, densely annulate. Relative lengths of setae: p 5100, p 9563(–65), p 05(35–)37(–39), r 5(30–)33. Tergal branch t (2.9–)3.0 times longer than greatest diameter and 1.8(–2.0) times as long as sternal branch s, the latter 1.4(–1.6) times as long as greatest diameter. Seta q 1.8 times as long as s. Relative lengths of flagella (base segment included) and base segments alone: F 15100, bs 1510; F 2554 (–58), bs 25 (5–)6; F 3594 (–96), bs 359. F 1 2.4(–2.5) times as long as t, F 2 and F 3 2.2(–2.3) and 3.7(–3.9) times as long as s, respectively. Globulus g 1.4(–1.5) times as long as greatest diameter; width of g 0.7 of greatest diameter of t .
Trunk. 4+4 setae on tergite I, 6+6 on II–IV, 6+4 on V, 4+2 on VI. Submedian setae somewhat clavate; lateral ones cylindrical, blunt. Genital papillae conical, 2.6 times as long as wide.
Bothriotricha. Relative lengths: T 15100, T 2583 (–90), T 35 (110–)120, T 45140, T 55160 (– 167). All with simple straight axes and sparse pubescence proximally, denser distally.
Legs. Coxa and trochanter of leg 9 with furcate setae; branches subcylindrical, striate; secondary branch somewhat longer than primary one. Setae on legs 1–8 with rudimentary secondary branches.
Tarsus of leg 9 3.9(–4.0) times as long as greatest diameter. Setae thin, pubescent, pointed, proximal one 0.5 length of tarsus, (2.2–)2.4 times as long as distal seta.
Pygidium. Tergum: posterior margin rounded with obtuse-angled triangular lobe projecting backwards posterior of a 1. Relative lengths of setae: a 15100, a 2548 (–50), a 35 (110–)113, st 524(–28). a 1 and a 3 thick, straight and tapering, with a few thick pubescence hairs; a 2 with sparse, long, thin pubescence; st cylindrical, diverging, with short pubescence. Distance a 1 – a 1 0.3(–0.4) length of a 1, distance a 1 – a 2 0.6(–0.8) of distance a 2 – a 3; distance st–st 0.4(–0.6) length of st and 0.3(–0.4) of distance a 1 – a 1.
Sternum: posterior margin rounded. Relative lengths of setae (a 15100): b 15 (93–)95, b 25 (59–)62(–63), b 35 (74–)79. b 1 subcylindrical, with dense pubescence, b 2 and b 3 tapering, with more sparse pubescence. Distance b 1 – b 1 0.7(–0.8) length of b 1, b 1 – b 2 0.6(– 0.7) length of b 2, b 3 0.8(–0.9) of interdistance.
Anal plate: broadest anteriorly, subtriangular, posteriorly rounded, directed backwards-downwards; as long as broad, with short pubescence, and on tergal side also some long hairs arranged irregularly. Two long cylindrical appendages protruding backwards from sternal side, which is curved inwards, cylindrical, pubescent, 0.7 length of plate.
