Newportia (Newportia) tequendama sp. nov.

Figs 29–41

Type material examined. Specimen not sexed, holotype from COLOMBIA: Reserva Natural Los Tunos, San Antonio del Tequendama, Cundinamarca (2225 m), 22.05.2012, leg. A. Chagas-Jr., S. Galvis, D. Triana and E. Chaparro (ICN.MCh-0277). Paratype: same data as holotype, specimen not sexed (ICN.MCh-1271).

Diagnosis. Cephalic plate without paramedian sutures. Anterior margin of forcipular coxosternite straight. Tergite 1 with an anterior transverse suture and incomplete paramedian sutures, only evident in the posterior margin of tergite 1 and immediately behind the anterior transverse suture. Legs 2–20 with only a lateral tibial spur and without tarsal spurs. Tarsi 1–22 clearly biarticulated. Prefemur of terminal legs with a series of four ventral spinous processes. Femur with small medial spinous process. Tibia with distal narrowing to a diameter similar to that of tarsus 1. Tarsi without a clear division between tarsus 1 and 2. Tarsus 2 not divided into different articles.

Etymology. The name of this species refers to the type locality, Tequendama. A noun in apposition.

Description of holotype.

Body length. 28.5mm; length of the ultimate legs: 8.8mm.

Color in alcohol. uniform dark yellow (Fig. 29).

Antennae. right with 17 articles and left with 16 (Fig. 30); three basal articles with some long setae, subsequent articles densely hairy. The first basal article is ventrally depigmented.

Cephalic plate. smooth, longer than wide, with a median sulcus below the anterior margin, and without paramedian sutures (Figs 30 and 31).

Forcipular segment. forcipular coxosternite surface without sutures and sulci with only subcondylic chitinous lines (Fig. 32). Anterior margin of the forcipular coxosternite straight, with two long chitinous lobes reaching the lateral margin of the trochanteroprefemur, separated by a median diastema (Fig. 32).

Locomotory legs. podomere surface with setae of different sizes. Legs 2–20 with only a lateral tibial spur. Without tarsal spurs. Tarsi 1–22 clearly biarticulated. Tarsus 1 and 2 longer than the tibia. Pretarsi long, with accessory spines.

Tergites. Tergite 1 partially overlapped by the posterior margin of the cephalic plate (Figs 30 and 31). Tergite 1 with complete anterior transverse sutures and incomplete paramedian sutures; transverse sutures in the posterior margin of tergite 1 interrupted by very short incomplete paramedian sutures (Fig. 31). Tergites 2–22 with complete paramedian sutures. Tergites 3–18 bearing oblique sutures. Tergites 2–21 with lateral longitudinal sutures (Figs 33 and 34). Tergite 23 longer than wide. Metatergites only visible at tergite 18.

Sternites. trapeziform. Sternites 2–22 and two incomplete lateral sutures. Sternites 2–21 with an incomplete median sulcus (Fig. 35). Sternite 23 longer than wide, trapeziform, with posterior margin concave (Fig. 36). Endosternites absent.

Coxopleuron. partially covered by pores of different sizes. Only a narrow band without pores observed near the superior margin. Coxopleural surface with few setae. Coxopleural process short. Posterior dorsal margin triangular (Figs 36 and 37).

Ultimate legs. prefemur (1.6mm) sub-triangular in transverse section, with a row of four ventral spinous processes, three proximal ones close to each other, and distal one more separate (Figs 38 and 40). Femur (1.7mm) cylindrical, with basal medial spinous process longer than ventral spinous processes of prefemur (Figs 38 and 40). Tibia (1.4mm) cylindrical, without a spinous process, shorter than the femur, with a distal narrowing that generates a diameter similar to tarsus 1 (Figs 38–40). Tarsi (4.1mm) divided uniformly, without a clear distinction between tarsus 1 and the beginning of tarsus 2. Tarsus 2 not clearly divided into different segments (Figs 38–40). Ultimate legs without pretarsus.

Variation in paratypes. The individual analyzed (ICN.Mch 1271) showed variation in the number of antennal segments compared to the holotype, in this case the individual has the same number of segments (17) in each antenna.

Habitat and sympatric species. The ecosystem where the species was found have the same characteristics in terms of vegetation, humidity, and precipitation as the type locality of N. anopla sp. nov. Only N. monticola Pocock, 1890, has been recorded in the same locality (Chagas-Jr et al. 2014).

Distribution. Known only from the type locality, in the central region of the country in the eastern Cordillera (Fig. 41).
