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.
