Type locality : Parque Forestal Embalse del Neusa, Tausa, Cundinamarca , Eastern Andes Mountains, Colombia . Diagnosis : As for subgenus. Description of holotype : Body length 12.70 mm , maximum width of cephalic plate 1.32 mm , length of cephalic plate 1.60 mm . Color of cephalic plate and antenna orange, trunk brown-reddish, legs yellowish ( Fig. 1-A ). Setae : Cephalic plate and ventral surface of forcipular segment sparsely covered by short thick setae (when these setae are lost, their round sockets are well visible); tergites and sternites 1–23 with sparse short thick setae; ultimate leg-bearing segment and penultimate sternite bearing more setae; legs 1–20 with lateral spurs. Antennae : 17 articles, slightly 2 times longer than cephalic plate, barely reaching anterior margin of tergite 3 when flexed; articles 1–3 with evidently longer and thicker setae (less numerous in article 3), articles 4–17 bearing a circlet of longer setae on its basal part, medial and distal part of articles 4–17 densely covered with small setae; ultimate article longest, ca. 1 ½ times as long as previous article. Cephalic plate : slightly longer than wide (1.2:1), anterior sides slightly rounded, with short paramedian sutures close to margin ( Fig. 1-B ). Maxillae 2 : Article 3 with well-developed dorsal brush ( Figs 1-D, E ). Pretarsus pectinated and long (slightly longer than half of telopodite article 3), consisting of two well-distinguishable halves: a dark brown basal and a semi-transparent apical one. Basal half short, apical part hyaline and thinner. Forcipules : coxosternite without any sutures but with well-developed dark chitin-lines and coxosternal condyles; forcipular trochanteroprefemur without process or toothplates.( Fig 1-C ). Tergites : Anterior margin of T1 covered by cephalic plate. T1 with an anterior transverse suture ( Fig. 1-B ) forming a very obtuse angle, and with paramedian sutures forked anteriorly, thus forming a “W”; paramedian sutures at T1 not exceeding transverse suture ( Fig. 1-B ). Sides of TT3-9 slightly curved anteriorly covering a small portion of pleura; TT 2–22 with complete paramedian sutures, TT3–20 with lateral longitudinal sutures, TT17-23 with lateral margination. Sternites : From SS8-21 with lateral sutures extending to the insertion of legs. S23 as long as wide at the base, strongly narrowed towards the definitely concave posterior margin ( Fig. 2-B ). Coxopleuron : with 41 coxal pores 18 of them small; coxopleural process 1/3 longer than S23. A small lateral portion of the pore-field is covered by S23. Posterior margin of ultimate pleuron forming an obtuse angle, its tip rounded. Coxopleural spines with 2 large setae at the basal and distal part ( Figs 2 C, D ). Legs : ( Fig. 2-E ) prefemur and femur slightly flattened dorsoventrally, with setae of different lengths; prefemur, femur and tibia with large seta at the ventral areas, these setae being twice longer and thicker than the rest of the leg setae; tibia 1–20 with lateral spur ( tls ), tarsus bipartite, tarsal spurs absent, pretarsus 1–22 with one accessory spine pretarsus claw-shaped ( Fig. 2-F ). Ultimate legs : prefemur triangular in cross section, with 3 ventral spinous processes, one basal and two ones closer to each other at distal end, with two rows of spine-like setae ventolaterally ( Fig. 3-A , ps ). Femur: with 2 short ventrolateral spinous processes on right leg and 1 short spinous ventral and 2 ventrolateral processes on left leg ( Fig. 3-B ,), with a porous area ventrally. Tibia: cylindrical, densely porous, with an uncinate distomedial lobe, ( Fig. 3-c 2 , Fig. 4-D ). Tarsus 1 cylindrical, slightly clavated, densely porous and with a “spinning-spur” (see below, Fig. 3-D ); tarsus 2 very short and thin, cylindrical, not segmented (continuous), setose, with various setae apically and without pretarsus ( Fig. 3-D ). Variability. Body length ranging between 5 and 13 mm . Color : larger individuals are brown-reddish, juveniles light yellow and very small juvenile of yellow-hyaline coloration, some specimens present 3 spinous process in one leg and 2 in the other. Ultimate legs : length / ratio of the ultimate article varies with developmental stage, juveniles with shorter prefemur, femur, tibia and T1, also the ultimate T2 and the “spinning-spur” on ultimate tarsus 1 breaks very easily if not handled gently, also when broken it’s not easily perceived under light microscopy.

Habitat : All specimens were collected at 3100 m .a.s.l, 16 ones during rainy season (June–January). 15 specimens were collected at 0-10 cm soil deep, and 3 at the 10-20 cm (Soil temperatures ranged from 9.6 C° to 10.4 C°, acidic soil (Ph = 3.5), low soil bulk and real density ( 0.3g /cm3 and 0.36 g /cm3), these soils has high aluminium content (25.10 cmol/kg) as well as soil organic carbón (29%), and nitrogen (1.30%), the dominant humus form of the organic litter was moder type ( Zanella, 2017 ) ( Figure 4 ). FIGURE 4. Habitat of Newportia (A.) shelleyi sp. n. ,—tropical mountain forest, 3100 m.a.s.l. Accompanied flora : All the individuals were collected inside a remnant of tropical montane forest, the dominant plant species in this forest was Weinnmania tomentosa L.F 1782, at the specific point of extraction, we identified leaf litter from Chusquea scandens , Kunth 1822 , Clusia multiflora Kunth 1822 , and Myrsine guianesis (Aubl.) Kuntze 1891 . Accompanied fauna : Newportia stolli Pocock, 1896 , N. monticola Pocock, 1890 , Taeniolinum neusicus Tulande-M, Prado & Triana, 2018. Schendylops sp. ( Chilopoda ), Chauliognathus sp. Carabidae , Ptilidae, Elateridae (Coleoptera) , Oonopidae, Opiliones (Chelicerata) , Cryptodesmus sp., Phaneromerium sp. ( Diplopoda ). Also, Enchytraeid earthworms and different kinds of Diptera larvae (mainly Sciaridae and Phoridae ) were identified as the potential prey items.
