With 16 (right) and 17 articles (left) ( Fig. 2 ); three basal articles with some long setae; subsequent articles densely hairy. Cephalic plate. Longer than wider ( Fig. 2 ) and with short paramedian sutures near the posterior margin ( Figs 2 and 3 ). FIGURES 1–4. Newportia ( Newportia ) florezi sp. nov. Holotype (ICN.MCh-0809). 1.

FIGURE 13. Habitat of Newportia ( Newportia ) florezi sp. nov. Rainforests of the biogeographic Chocó, Rio Ñambi Nature Reserve. 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 ). 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 ). 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 ). 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 ). Tergite 23 longer than wide, without sutures, but marginated laterally ( Fig. 7 ). Sternites. Sternites 2–22 with incomplete longitudinal median sulcus. Sternites 2–21 with incomplete longitudinal lateral sulci ( Fig. 8 ). Sternite 22 laterally marginated. Sternite 23 trapeziform, larger than wide, with a concave posterior margin ( Fig. 9 ). 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 ). Ultimate legs. Prefemur ( 1.3mm ), triangular in transverse section, with a row of four large ventral spinous processes ( Figs 9 and 11 ), with a series of six small dorsomedial spinous processes ( Fig. 12 ), each with a subapical seta ( Fig. 11 ); apical spinous process bifurcate, each with a subapical seta ( Fig. 11.1 ). Femur ( 1.1mm ) cylindrical, with two large spinous processes, one lateral and one ventral ( Figs 9–12 ). Tibia ( 1mm ) cylindrical, without spines, and shorter than femur ( Fig. 12 ). Tarsus 1 ( 0.5mm ), clearly separated from tarsus 2. Tarsus 2 ( 1.8mm ), with seven articles, clearly divided ( Fig. 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 ) 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 ).
