Calima nutabe sp. nov.

( Figures 6–8 , Table 1)

Type material

Holotype: COLOMBIA: Antioquia department: One adult male from Angelopolis municipality, El Romeral Reserve , 6°7’30.00“N, 75°41’58.47“W, 2022 m asl, manual capture under

plant debris, 20 December 2011, A. Pérez ( ICN Asc-056, #1). Paratypes: one adult male ( ICN Asc-056, #2), same data as the holotype .

Etymology

Named after the Nutabe (in Spanish) a native tribe that prevails in the geographic valley of the Cauca river, in the Antioquia department, Colombia .

Diagnosis

The males of this species, share with C. valenciorum and C. embera , a flagellum with a single dorsomedian swelling (Dms) before the seta Dm4 ( Figure 7 (f)), but it differs from them by having a sub-oval flagellum ( Figure 7 (a,b,d,e), whereas C. valenciorum and C. embera have sub-rhomboidal flagella ( Moreno-González and Villarreal 2012: figs 23–24; Figure 3 (a,b,d,e)).

Description

Male holotype (ICN-Asc-056, #1) ( Figure 6 (a, b)). Coloration (in ethanol 70%): general pattern dark greenish-brown. Chelicerae reddish and flagellum light brownish. Pedipalps: all segments dark reddish-brown. Anterior and posterior sterna light greenish-brown. Legs: coxae and trochanters I–IV, light greenish-brown; femora and patellae I–IV, dark greenish-brown; tibiae II–IV dark greenish-brown, except for tibia I that is light reddish-brown; tarsus II–IV light greenish-brown, except for tarsus I that is light reddishbrown. All body setation dark reddish-brown.

Prosoma ( Figure 6 (a)). Anterior process of propeltidium with two setae (one behind the other) followed by three pairs of dorsosubmedian setae; eyespot sub-oval; metapeltidium entire. Anterior sternum with 4 + 8 setae and posterior sternum with six setae. Measurements ( Table 1).

Chelicerae ( Figure 7 (i, j)). Movable finger ( Figure 7 (i)) sharp and curved distally, serrula, composed of 19 hyaline teeth, increasing in size towards distal region, guard tooth and lamella present. Fixed finger ( Figure 7 (j)) with six similarly sized teeth between two large outer ones. Setation: G1 (setae group 1) with three spatulate setae, one (most dorsal) with basal surface almost smooth, two remaining with basal surface covered with almost four longitudinal rows of spinose spicules; G2 composed of five feathered setae, all subequal in length and longer than movable finger length; G3 with four setae subequal in length, each one consisting of dorsal feathered and ventral serrated surfaces; G4 consisting of two smooth, short and thick setae with thin apex; G5A with nine setae subequal in length, feathered apically and longer than the movable finger length; G5B with 10 setae, feathered apically and longer than G5A setae length; G6 with one smooth seta longer than half of movable finger length; G7 with six setae feathered from the middle to its apex, decreasing in size from proximal to distal. Setal group formula (G1:G2: G3:G4:G5A:G5B:G6:G7): 3-5-4-2-9-10-1-6.

Pedipalp ( Figure 7 (g)). All segments smooth, without armature, two times longer than propeltidium length. Trochanter: with mesal spur, two times longer than high, with an apical process rounded and not projected; with one ventral row of large setae, with an intermediate row of small setae over the external face; internal face with a row of three setae over the ventral edge, and two setae over the dorsal edge. Femur: subcylindrical, 1.8 times longer than high, dorsal edge two times longer than ventral edge, thinner at base and wider at apex; ventral edge on external surface with setae Fv1 and Fv2 well developed and near each other, external surface more laterally with Fe1 and Fe2, not near each other ( Figure 7 (g)); internal surface with a row of ventral setae Fvr1–3 and with two dorsal setae Fd1 and Fd2 ( Figure 7 (h)). Patella: cylindrical, 2.2 times longer than higher, distal edge 1.3 times longer than basal edge of segment, ventral region with setae Pe3, Pe4 and Pe5, Pe4 small located medially at the same level of Pe5, also with setae Pm 1–5 in a row except for Pm3, which was located medially, all feathered distally and not spiniform (same setation pattern as for C. embera ). Tibia: Cylindrical, three times longer than high, base as high as patella; thin and longer than patella, ventral region with setae Ter4–6, not feathered distally and not spiniform, with a small Tm seta, and with setae Tmr3–5 and Tir2–5, all feathered distally and not spiniform (same setation pattern as for C. embera ). Tarsus: 2.8 times longer than high, approximately half the length of tibia; tarsal claw sharp and curved, length subequal to the length of tarsus; tarsal spurs asymmetrical.

Opisthosoma ( Figure 6 (a, b)). Setae: Tergite I with two pairs of microsetae; Tergite II with three pairs of microsetae. Tergites I–IX each with one pair of large Dm setae; tergites VIII–IX each with one pair of Dl2 setae. Sternites I–III each with a row of scattered microsetae; sternite IV with seta Vm1 and setae Vm2, Vl1A, Vl1B and Vl2; sternites V–VIII with setae Vm2, Vl1 and Vl2; sternite IX the same setae as for sternites V–VIII but with seta Vm1. Segment X with seta Vm1 and setae Vm2, Vl1 and Vl2; segment XI with seta Vm1 and setae Vm2, Vl1 and Dl1; segment XII with setae Dm, Dl1, Dl2, Vm2, Vl2, Vl1A and Vl1B. Segment XII without posterodorsal process. Respiratory spiracles large and oval, slightly sclerotized and darker than sternites.

Flagellum ( Figure 7 (a–f)). Dorsoventrally flattened, sub-oval and short, with lateral margins of the bulb sub-parallel in dorsal view; 1.6 times longer than wide and 4.1 times longer than pedicel length. With one pair of shallow, wide and not marked dorsosubmedian depressions between Dl2 and Dm4; without any dorsal swelling, except for a single dorsomedian swelling (Dms) before the setae Dm4. Setation: Vm1 at same level as Dm1; pair Vm2 absent; pair Vm3 distal to Vm1 level; Dl2 positioned proximal to Vl1; Vm5 proximal to Dm4; Vl2 proximal to Dl3 level. With one irregular patch composed of six or seven microsetae from the level of Vm5 to same level of Dl3. With one pair of dorsosubmedian microsetae between Dm1 and Dl2, and one pair of lateral microsetae over the pedicel (see Discussion for details on male flagellum microsetae).

Female

Unknown.
