Type material examined. Specimen not sexed, Holotype from COLOMBIA: Reserva Natural Río Ñambi , Altaquer , Barbacoas , Nariño (1.28455, -78.08840, 1255 m), 2–6.vii.2017, leg. W. Galvis ( ICN.MCh-0809) GoogleMaps ; Paratypes: same data as holotype, 3 specimens not sexed ( ICN.MCh-0810—1 ind., ICN.MCh-1140—2 ind.) .

Diagnosis. Posterior margin of the cephalic plate with short paramedian sutures. Tergite 2 with an anterior transverse suture. Sternite 23 with lateral margins. Legs 1–20 with a lateral tibial spur. Prefemur of ultimate legs with four large ventral spinous processes: a series of 5–6 dorsomedial spinous processes each accompanied by a subapical seta; the apical spinous process is bifurcated and in each end with a subapical seta ( Fig. 11.1 View FIGURES 9–12 ). Femur of ultimate legs with two large spinous processes, one ventral and one lateral. Tibia shorter than femur. Tarsus 1 clearly separated tarsus 2. Tarsus 2, with seven clearly divided articles.

Etymology. The specific name is dedicated to Professor Eduardo Flórez Daza, the great supporter, and enthusiast of myriapods studies in Colombia.

Description of holotype.

Body length. 22.5 mm; ultimate leg length: 5.7 mm.

Color in alcohol. Cephalic plate, tergites 1, 2, and 23 dark yellow, remaining segments lighter ( Fig. 1 View FIGURES 1–4 ).

Antennae. With 16 (right) and 17 articles (left) ( Fig. 2 View FIGURES 1–4 ); three basal articles with some long setae; subsequent articles densely hairy.

Cephalic plate. Longer than wider ( Fig. 2 View FIGURES 1–4 ) and with short paramedian sutures near the posterior margin ( Figs 2 and 3 View FIGURES 1–4 ).

Forcipular segment. Coxosternite without transverse sutures, only chitinous lines. Anterior margin of coxosternite convex, with two chitinous lobes separated by a medium diastema, each accompanied by a bristle. Trochanteral suture present ( Fig. 4 View FIGURES 1–4 ).

Walking legs. All podomeres covered with long setae. Legs 1–21 with a lateral tibial spur, without tarsal spurs. Tarsi is not divided into tarsus 1 and 2 (unarticulated). Pretarsi long and with two small accessories spurs.

Tergites. Tergite 1 with an anterior transverse suture; paramedian sutures ending at the anterior transverse suture ( Fig. 3 View FIGURES 1–4 ). Tergite 2 with a short anterior transverse semicircular suture, a complete paramedian suture crossing the semicircular suture and ending at the anterior margin; below the semicircular sulcus, a straight transverse sulcus is observed, interrupted by the paramedian sutures ( Fig. 3 View FIGURES 1–4 ). Tergites 2–22 with complete paramedian sutures. Tergites 3–20 with oblique sutures. Tergites 15–19 with longitudinal lateral sutures. Tergites 5–20 with a median keel. Pretergites visible from tergites 2–9 and tergites 15–20 ( Figs 5 and 6 View FIGURES 5–8 ). Tergite 23 longer than wide, without sutures, but marginated laterally ( Fig. 7 View FIGURES 5–8 ).

Sternites. Sternites 2–22 with incomplete longitudinal median sulcus. Sternites 2–21 with incomplete longitudinal lateral sulci ( Fig. 8 View FIGURES 5–8 ). Sternite 22 laterally marginated. Sternite 23 trapeziform, larger than wide, with a concave posterior margin ( Fig. 9 View FIGURES 9–12 ).

Coxopleuron. Partially covered by pores of different sizes, separated from each other. Only the coxopleural process and a narrow band surround the superior and posterior margins of the coxopleura, without pores. Coxopleural surface without setae. The coxopleural process is long, sharp, and ends in a thorn ( Fig. 10 View FIGURES 9–12 ).

Ultimate legs. Prefemur (1.3mm), triangular in transverse section, with a row of four large ventral spinous processes ( Figs 9 and 11 View FIGURES 9–12 ), with a series of six small dorsomedial spinous processes ( Fig. 12 View FIGURES 9–12 ), each with a subapical seta ( Fig. 11 View FIGURES 9–12 ); apical spinous process bifurcate, each with a subapical seta ( Fig. 11.1 View FIGURES 9–12 ). Femur (1.1mm) cylindrical, with two large spinous processes, one lateral and one ventral ( Figs 9–12 View FIGURES 9–12 ). Tibia (1mm) cylindrical, without spines, and shorter than femur ( Fig. 12 View FIGURES 9–12 ). Tarsus 1 (0.5mm), clearly separated from tarsus 2. Tarsus 2 (1.8mm), with seven articles, clearly divided ( Fig. 12 View FIGURES 9–12 ). Ultimate leg without pretarsus.

Variation in paratypes. The number of antennal segments varies compared to the holotype; in the paratypes, the number of antennomeres (17) is the same for both antennae. Furthermore, the number of dorsomedial spinous processes of the prefemur also varies; while there are six in the holotype, it can vary from five to six in the paratypes, in both legs (there are no differences between the right and left legs).

Habitat and sympatric species. The type locality of this species is in the biogeographical Colombian province of Chocó. This region is characterized by high precipitation, reaching up to 7100 mm of annual precipitation, with an average temperature of 19 °C ( Gutiérrez et al. 2004). The vegetation cover comprises several species of trees, shrubs, lianas, and epiphytes, primarily of the Rubiaceae , Araceae , and Melastomataceae families ( Gutiérrez et al. 2004). All the above results reveal the typical characteristics of a rainforest with dense vegetation ( Fig. 13 View FIGURE 13 ) and a canopy up to 30 m high. Other Newportia species have been registered in the same locality, including N. fuhrmanni Ribaut, 1912 ; N. simoni Brölemann, 1898 ; and N. adisi Schileyko & Minelli, 1999 ( Chagas-Jr et al. 2014; Galvis et al. 2015).

Distribution. Known only from the type locality, in the extreme south of the country, at the foot of the Cordillera, almost on the border with Ecuador ( Fig. 41 View FIGURE 41 ).
