New records of Pauropoda (Myriapoda) with descriptions of new taxa Scheller, Ulf Zootaxa 2014 3866 3 301 332 9B86X [151,432,667,690] Pauropoda Pauropodidae Decapauropus Animalia Tetramerocerata 14 315 Arthropoda species extremus sp. nov.    Typespecimen. Holotype: ad. 9 (♀), Mexico, Yucatan, ca. 100 kmS from Merida, between Lol-Tun and Labna, ca. 20°12′N, 89°32′W; 50 ma. s. l, tropical forest, in leaf litter, September 11, 2002, W. Niedbała leg. Typespecimen deposited in the Zoological Museum, University of Lund, Sweden.   Diagnosis.In most pauropods the seta qon the lower side of the sternal antennal branch shas its insertion point in the middle. In a few cases, however, in the genera  Pauropus, Decapauropus, Propepauropus, Hemipauropusand  Brachypauropusthe insertion point is distinctly displaced into the anterior half of the branch but such an extremely distal position as in  D. extremus  n. sp.has not been observed before. Thereby and together with the circular shape of the anal plate and the unusually long a-setae of the pygidium the new species is well defined.  Derivation of name.From the Latin  extremus= outermost, referring to the subdistal insertion of the seta qof the sternal antennal branch.   Description. Length: 0.96 mm.  Head(Fig. 11). Tergal setae long thin blunt, striate densely. Relative lengths of setae, 1st row: a1 = a2 = 10; 2nd row: a1 = a3 = 12, a2 = 13; 3rd row: a1 = 11, a2 = 13; 4th row: a1 = 11, a2 = 26, a3 = 17, a4 = 13, lateral group setae thin pointed, l1 = 22, l2 = 21, l3 = 20. Ratio a1 /a1– a 1 in1st row 1.5, 2nd 0.9, 3rd 1.6 and 4th row 1.3. Temporal organs in tergal view longish, length 0.5 of shortest interdistance. Head cuticle glabrous.  Antennae(Fig. 12). Segment 4 with 5 thin cylindrical striate setae, rthinnest, their relative lengths: p= 10, p'= 5, p''rudimentary, r =6. Tergal seta p0.7 of the length of tergal branch t. The latter 5.1 times as long as its greatest diameter and 1.3 times as long as sternal branch s, that branch 2.6 times as long as its greatest diameter; anterodistal corner of sdistinctly truncate, particularly inside flagella F2. Seta qas pand p´of 4th segment, 0.7 of the length of s, insertion point just below the base of F2. Relative lengths of flagella (basal segments included) and basal segments: F1 = 100, bs1 = 8; F2 = 49, bs2 = 5; F3 = 80, bs3 = 5. The F1 2.1 times as long as t, F2 and F3 1.6 and 3.1 times as long as srespectively. Distal calyces very small, conical, distal part of flagella axes not widened below calyces. Globulus galmost cylindrical, 1.1 times as wide as long, ≈10 bracts, capsule with flattened bottom, width of gas long as greatest width of t. Antennae glabrous.  Trunk(Figs 13–14). Setae of collum segment (Figure 13) similar, furcate, main branch cylindrical, blunt, annulated, striate, secondary branch cylindrical too and shorter but not studied in detail, sternite process small, narrow anteriorly, appendages with flattened caps, process and appendages pubescent. Setae on anterior tergites similar to submedian setae of head and lengthening posteriorly, on posterior tergites long pointed; 4+4 setae on tergite I, 6+6 on II-V, 4+2 on VI. Submedian posterior setae on tergite VI (Figure 14) long, thin, pointed, somewhat curved inwards, length 1.1 times as long as interdistance and 1.3 times as long as the length of pygidial setae a1. Tergites glabrous.  Bothriotricha(Figs 15–16): relative lengths: T1 = T2 = 100, T3 = 82, T4 = 65, T5 = 129; axes simple, T1 (Fig. 15) and T2 very thin, proximal halves glabrous, distal halves with long sparse, partly branched hairs; T3 and T5 thicker, the former (Fig. 16) with oblique simple pubescence hairs, the latter with very delicate pubescence.  Legs(Figs 17–18). Setae on coxa and trochanter (Fig. 17) of leg 9 furcate, branches cylindrical, blunt, striate, secondary branch somewhat shorter than primary branch. Tarsus of leg 9 (Fig. 18 )distinctly tapering, 4.7 times as long as its greatest diameter; setae cylindrical, proximal seta long, tapering, very thin distally, glabrous, distal seta short, cylindrical, blunt, with short pubescence, proximal seta 0.6 of the length of tarsus and 5.8 times as long as distal seta. Cuticle of tarsus glabrous.  FIGURES 11–19.  Decapauropus extremus  n. sp., holotypead. 9 (♀). 11. Head, right half. 12. Right antenna, sternal view. 13.

Pygidium, median and left part, sternal view. Scale: a: 11, 14, 13, 15; b: 12, 16–19.  Pygidium(Fig. 19): Tergum: Posterior margin evenly rounded. Relative lengths of setae: a1 = 10, a2 = 13, a3 = 24 and 25; all setae directed posteriorly, a-setae long, thin, tapering, pointed glabrous, a1 almost straight, a2 and a3 somewhat curved inwards, stcylindrical. blunt, with distinct but short pubescence. Distance a1– a1 0.6 of the length of a1; distance a1– a2 1.4 times as long as distance a2– a3; distance st–sttwice longer than stand 0.4 of the length of distance a1– a1. Cuticle glabrous.  Sternum: Posterior margin between b1 indented shallowly and with low broad lobe below anal plate. Relative lengths of setae (pygidial a1 = 10): b1≈11, b2 = 5; setae tapering pointed, striate weakly distally, b2 curved inward and converging; b1 about as long as interdistance, b2 as long as distance b1– b2. Anal plate circular, glabrous, two short setiform appendages protruding backwards from distal part of sternal side, these cylindrical blunt, length half of the length of the plate.
