Figs 14–28, 41
Type material examined. Specimen not sexed, Holotype from COLOMBIA: Vereda Catalamonte, Reserva Natural Tenasucá, Tena, Cundinamarca (4.69255, -74.38910, 2150 m), 22.vi.2019, leg. S. Galvis, W. Galvis and D. Martínez (ICN.MCh-1207). Paratypes: same data as holotype, 2 specimens not sexed (ICN.MCh-1208, ICN.MCh-1209).
Diagnosis. Forcipular coxosternite reduced, giving the appearance of short forceps relative to the length of the cephalic plate. Tarsungula flattened dorsoventrally. T1 overlaps the posterior border of the cephalic plate, without an anterior transverse suture and with four short sutures near the anterior margin. Coxopleural processes are absent. Ultimate legs densely covered with setae. Prefemur with two small ventral spinous processes. Femur and tibia without spinous process. Tarsus divided uniformly without distinction between tarsus 1 and the beginning of tarsus 2. Tarsus 2 with 11 articles being clearly divided.
Etymology. This species name ‘ anopla ’ Greek anoplos, ‘without armor’, ‘unarmed’ alludes to the absence of the coxopleural process.
Description of holotype.
Body length. 18.5mm; length of the ultimate legs: 7.4mm.
Color in alcohol. Cephalic plate, Tergites 1–2 and T22–23 dark yellow, tergites, pleurites and sternites 3–22 uniform light yellow (Fig. 14).
Antennae. Right antennae with 12 articles and left with 17 (Fig. 15); two basal articles with long setae, subsequent articles densely hairy. The first basal article ventrally depigmented.
Cephalic plate. Smooth, longer than wide. Anterior margin near the base of each antenna with a whitish spot in the form of a small suture directed posteriad (Fig. 16).
Forcipular segment. Coxosternite reduced to three times wider than long (Fig. 17). Anterior margin convex, with two chitinous lobes separated by a median diastema and two small depressions just below each lobe (Fig. 17). Trochanteroprefemur with small distal process. Tarsungula of the usual size and proportion (Fig. 18), flattened dorsoventrally (Fig. 19).
Locomotory legs. Surface of all podomeres with numerous setae of different lengths. Legs 2–20 with a lateral tibial spur. Without tarsal spurs. The tarsi of legs 1–21 clearly not distinct from tarsi 1 and 2 (unarticulated), which are longer than the tibia. Pretarsi long and without accessory spur. Leg 22densely covered by setae, with a biarticulated tarsus.
Tergites. Tergite 1 overlapping the posterior margin of the cephalic plate, without anterior transverse suture, and with four short sutures near the anterior margin (Fig. 20). Tergites 2–3 with short paramedian sutures at the anterior margin (Fig. 16). Tergites 4 and 21 with incomplete paramedian sutures. Tergites 5–20 with complete paramedian sutures; these sutures were thin in front of the tergite and widened in the back. Tergites 5–20 with oblique sutures (Fig. 21). Tergites 5–21 with lateral longitudinal sutures (Fig. 22). Tergites 22 with paramedian sutures shortened at the posterior margin. Tergites 23 wider than long, pentagonal, with median longitudinal depression, and bearing several setae (Fig. 23). Pretergites are visible in tergite 3 and tergites 5–22, all with paramedian sutures (Figs 21 and 22).
Sternites. Sternites 1–2 wider than long; Sternites 3–21 longer than wide; Sternites 22–23 as wide as long. Sternites 1–22 with two incomplete lateral sutures (Fig. 24). Endosternites present, with anterior margin convex; visible in segments 4–21 (Fig. 24); not visible in segments 1–3 and 10–22. Sternite 23 was noticeably smaller than sternite 22, a square shape, with a straight posterior margin and some long setae on its surface (Fig. 25).
Coxopleuron. Partially covered by pores of different sizes and well separated from each other. Only a narrow band without pores observed near the superior margin. The number of pores was reduced. Coxopleural surface with some setae, but distal inferior portion more densely setose. Coxopleural processes absent (Fig. 25).
Ultimate legs. Podomeres densely covered by short setae. Prefemur (0.9 mm) sub-triangular in transverse section, with only a row of two very small ventral spinous processes (Figs. 25, 26). Femur (1mm) cylindrical, without spinous processes, longer than the prefemur (Fig. 26). Tibia (1mm) cylindrical, without spinous processes, and shorter than the femur (Fig. 26). Tarsi divided uniformly without a clear distinction between tarsus 1 (0.6 mm) and the beginning of tarsus 2 (Fig. 26). Tarsus 2 (3.9 mm) with 11 articles, clearly divided (Fig. 26). Posterior half of tarsi 1 and 2 depigmented and lighter in color than the rest of the body. Ultimate leg without pretarsus.
Variation in paratypes. In one of the paratypes a variation in the number of antennal segments was observed (right with 17 segments, left with 14). As for the ultimate legs, the prefemur of the left leg has the same shape, however, it has three ventral spinous processes (one more than in the holotype), the right leg has two, the same as the holotype.
Habitat and sympatric species. The type locality has secondary cloud forest vegetation (Fig. 28) on an undulating relief with some steep areas (CAR 2013). Due to its altitude, atmospheric pressure is low. The winds are moderate. Therefore, humidity is high in these forests, while the light and temperature regimes are low (Naranjo & Rivera 1992; García et al. 2014). Therefore, it is possible to observe soils that are rich in organic matter, not very compact and contain abundant leaf litter. The forest has a heterogeneous composition: a mixed forest with a predominance of the families Fagaceae, Lecythidaceae, Solanaceae, Meliaceae, Lauraceae, and Moraceae, and an oak forest (Quercus humboldtii), in addition to elements of the sub-Andean and Andean forests in important proportions, constituting it in ecotones between these life zones (Cobaleda 1991; CAR 2013).
According to the data from the catalogue of the collection where the specimens of N. anopla sp. nov. are deposited, other species of the same genus can be found in the same locality, such as: Newportia stolli (Pocock 1896) (ICN M.Ch 1150, ICN M.Ch 1215, ICN M.Ch 1216), Newportia monticola Pocock 1890 (ICN M.Ch 1198) and Newportia adisi Schileyko & Minelli 1999 (ICN M.Ch 1202).
Distribution: Known only from the type locality, in the central region of the country in the eastern Cordillera (Fig. 41).
