Paratropis papilligera FO Pickard-Cambridge, 1896 Figure 4

Type material.

Holotype male and paratype female from Santarem, Pará, Brazil, deposited in NHM, only male examined.

Additional material examined.

Colombia, Amazonas, Leticia, km 11 road to Tarapacá, 100 m, 25-iv-2002, it was collected manually in the day on leaf litter, col. G Amat and Estudiantes Introducción Sistemática Animal - Universidad Nacional de Colombia, 1 male (ICN-Ar 2315).

Emended diagnosis.

Males of P. papilligera differ from those of other Paratropis species by the morphology of the palpal bulb with very thin and long embolus, distally curved (Figure 4F, G), and by the tibia I with a basal retrolateral conic process with spiniform setae (Figure 4D, E).

Redescription.

Male (ICN-Ar 2315) (Figure 4): total length 12.3; carapace length 6.1, width 6.8; abdomen length 5.4, width 3.3; chelicerae length 2.7. Color (in alcohol): body with soil particles encrusted; carapace and chelicerae dark reddish brown, legs and abdomen brown (Figure 4A). Carapace slightly setose, striae conspicuous, lateral margins with single line of curved setae mixed with disperse clubbed setae; caput arched, separated from thoracic region by transverse shallow fovea, straight, width 1.0 (Figure 4A). Eyes and ocular tubercle: tubercle length 1.10, width 1.40, very elevated (height 0.9) and forwardly directed, with few stout setae. Clypeus absent. Anterior eye row slightly procurved, posterior recurved. Ocular sizes and interdistances: AME 0.45, ALE 0.35, PME 0.23, PLE 0.33, AME-AME 0.10, AME-ALE 0.08, PME-PME 0.63, PME-PLE 0.05, ALE-PLE 0.08, AME-PME 0.05, ALE-ALE 0.93, PLE-PLE 0.80. Chelicerae: short sparse bristles on dorsal and lateral areas, long fine bristles on ventral and anterior area. Rastellum absent. Cheliceral furrow with two rows of teeth well developed, 10/10 and 9/10 teeth on promargin and retromargin, respectively. Fang long. Labium: length 0.8, width 1.4, with 105 cuspules on anterior edge (Figure 4C). Labio-sternal groove narrower in the middle than laterally. Maxillae longer than wide, with the anterior prolateral lobe very elongated, conical (Figure 4C); with 73/72 rounded cuspules spaced, largely spread over prolatero-ventral border from the inner edge to anterior lobe. Lyra absent. Sternum: length 2.7, width 3.4; three pairs of sigillae, anterior subcircular, median and posterior sigillae oval; anterior and median sigillae marginal, posterior submarginal. Anterior edge of sternum with a semicircular area slightly elevated (joined to labio-sternal groove) (Figure 4C).

Legs: cuticle with soil particles encrusted. Leg and palpal segments measurements provided in Table 4. Leg I clearly thicker than the others. Bristles, plumose and thorn-like setae and spines evident. Tibia I with a basal retrolateral conic process with spiniform setae (Figure 4D, E). Trichobothria: filiform, on central 2/3 of tarsi, palp 6, leg I 9, II 8, III 7, IV 8; on distal 1/4 of metatarsi, leg I 5, II 4, III 4, IV 4; on proximal 1/3 of tibiae, palp two rows of 4 each, leg I two groups of 5 each, II-III two groups of 4 each, IV 2r-5p-1d (proximal/distal). Scopulae absent. Pseudoscopula weak and divided by conical longer setae, only present on distal tarsi I and II; tarsi III and IV with few sparse pseudoscopula setae. Claw tufts absent. Tarsal claws: ITC only present on leg I; STC with one tooth on all legs. Spination: principally thorn-like setae on all segments. Spines: palp 0; leg I 0; leg II 0; leg III, fe 0, pa 0, ti 0, me 1p 1v, ta 1p; leg IV, fe 0, pa 0, ti 0, me 1p, ta 1p.

Palp: cymbium with two unequal lobes separated by a sclerotized groove; tibia with shallow distoventral groove. Palpal bulb elongated; embolus very thin and long (longer than tibia), distally curved, tapering to the apex (Figure 4F, G).

Abdomen: with four longitudinal dorsal rows of seven small tubercles, each emitting from its summit a plumose, bacilliform seta; lateral area finely tuberculate, with smaller plumose setae. Book lung apertures projected, oval, sclerotized (Figure 4B). Spinnerets: PMS length 0.50; PLS length 3.00, apical segment digitiform. Basal segment of PLS divided in two unequal cuticle plates (Figure 4B).
