Calima valenciorum sp. nov.

( Figs 23–42 , 45 , Table 1)

Type material. Holotype: COLOMBIA, Valle del Cauca: adult male (flagellum with a dorsal slight wound healed, Figs 24, 27 )from Bellavista farm, Arauca sidewalk, Andinápolis, Trujillo municipality, 1637 m.a.l.s., 04°10’09.8”N 76°24’04.8”W, night manual capture, under a rotten log 15.X.2011, J. A. Moreno-González (MUSENUV-23553). Paratypes: COLOMBIA, Valle del Cauca: 1 adult female (MUSENUV- 23554) and one juvenile (MUSENUV-23555) same data as holotype; 1 adult female (ICN-ASc-047) same data as holotype.

Etymology. Named honoring the Valencia family from Bellavista farm, whose hospitality and conservation practices allowed the collection of the specimens.

Diagnosis. Total length 3.37–3.44 mm (flagellum not included). Male flagellum 1.6 times longer than wide and 5.7 times longer than pedicel length, with setae Vl2 at same level of Dl3. Spermathecae with one pair of lobes whose bases are in contact; with semi-oval receptacula more thicker than stalk; with a sclerotized “duct” connecting receptacle and stalk.

Description. Male holotype. Coloration. General pattern dark greenish-brown, same of Calima bremensis , except for: Femur I dark reddish-brown, II–IV dark greenish-brown; Patella I dark reddish-brown, II–IV light greenish-brownish.

Prosoma. Anterior process of propeltidium with 2 setae (one behind the other) follow by 3+1 pairs of dorsosubmedian setae (females only have 3 pairs, is it possibly that this male has an additional pair); eyespot suboval; metapeltidium entire. Anterior sternum with 3+8 setae and posterior sternum with 5 setae.

Opisthosoma. Setae: Tergite II with 3 pairs of microsetae. Tergites I–VII each with 1 pair of large dorsosubmedian setae; VIII–IX each with one pair of dorsosubmedian setae and one pair of distolateral setae; segment X with 7 setae in a ventral row; segment XI with 7 setae, 2 lateral setae and 5 ventral setae; segment XII with 14 setae, 2 dorsal setae and 12 setae in a ventral row. Segment XII without posterodorsal process. Respiratory spiracles large and oval, slightly sclerotized and darker than sternites. Sternites I–II with approximately 7 rows of microsetae, III–IX each with 1 row of transverse microsetae.

Flagellum ( Figs 23–28 ). Dorsoventrally flattened, sub-rhomboidal shaped and short, 1.6 times longer than wide and 5.7 times longer than pedicel length. Setation: Vm1 at same level as Dm1; pair Vm2 absent; pair Vm4 proximal to Dl1 level; Dl1 positioned proximal respect to Vl1; Vm5 proximal to Dm4; Vl2 at same level of Dl3. One pair of lateral microsetae at Vm1 level; 1 pair between Dm1 and Dl1, and 1 irregular “patch” compost of 5-6 microsetae since level of Vm5 to Vl2. With one pair of dorsosubmedian depressions between Dl1 and Vm5; without any dorsal swelling.

Chelicerae ( Figs 29 – 30 ). Movable finger ( Fig. 29 ) sharp and curved distally, serrula, composed of 20 hyaline teeth (1 small and 19 large), increase in size toward distal region, guard tooth elongated. Lamella tricuspid and small. Fixed finger ( Fig. 30 ) with 5 similar sized teeth between 2 large outer teeth. Setation: G1 with 3 spatulate setae, 1 (most dorsal) with basal surface almost smooth, 2 remaining with basal surface cover with almost 4 longitudinal rows of spinose spicules. G2 composed of 5 feathered setae, all subequal longer than movable finger length; G3 with 4 setae, each one consisting of dorsal feathered and ventral serrated surfaces; G4 consisting of 2 setae, smooth, short and thick with thin apex; G5 with 7 similar sized feathered setae and G6 with 1 smooth setae longer than half of movable finger length. Setal group formula: 3-5-4-2-7-1.

Pedipalp ( Fig. 31 ). All segments smooth, without spinose setae. Trochanter: With mesal spur present, 1 ventral row of 5 large setae with an intermediate row of small setae, with a frontal process rounded, not projected. Femur: subcylindrical 1.7 times longer than high; dorsal edge 3.5 times longer than ventral edge, thinner at base and wider in apex, lateral external surface with 2 large setae and 2 small setae. Patella: cylindrical, 2.1 times longer than higher, distal edge 1.2 times longer than basal edge of segment, at least with 2 rows of dorsal setae, 1 row on lateral and 2 rows on ventral. Tibia cylindrical, 3.2 times longer than high, base as higher as patella; thin and longer than patella, with at least 2 ventral, 1 lateral, 2 dorsal, and 3 ventral rows of setae. Tarsus: approximately half length of tibia, with numerous setae; tarsal claw sharp and curved, slightly larger than half tibial length, tarsal spur present.

Female description. Paratype (MUSENUV-23554). Coloration and setation same as male, differs only in sternites I–II which have 4 rows of microsetae.

Flagellum ( Figs 32–37 ). With 4 segments, 5.8 times longer than wide; with same setal pattern as C. bremensis .

Chelicerae ( Figs 38–39 ). Similar to male, lamella is small with only 1 cusp present; setation similar to male, except for setal group formula 3-5-4-2-9-1.

Pedipalp ( Fig. 40 ). Simple, similar to male.

Spermathecae ( Fig. 41 ). Consists of 1 pair of lobes, with thick stalks “C”-like curved, whose bases are in contact; with apex directed to median region; stalks with distinct terminal large semi-oval sclerotized bulbs (receptacula) more thicker than stalk with a basal membranous and rounded eminence pronounced dorsally; with a sclerotized “duct” connecting receptacula to ventral region of stalks, ventral region of receptacula covered with numerous duct openings; chitinized arch barely evident and slight developed, only with their lateral triangular points strongly sclerotized; gonopod absent.

Distribution ( Fig. 42 ). Only know from it type locality, located in Western Colombian Andes.

Natural history. All individuals were collected at night under and inside of rotten logs in an Andean forest fragment of 4 ha in extension. This fragment was completely surrounded by coffee and banana plantations under intensive management, therefore probably will be destroyed ( Fig. 45 ). Juveniles were found inside a rotten log at daylight approximately to 30 cm of deep, not ant or termite were found nearby of any observed individual; one male and one female (holotype and paratype respectively) were captured together.

Comparisons. Calima valenciorum sp. nov. can be differentiated of C. bremensis sp. nov. by the following combination of characters: (1) male flagellum length/ width ratio of 1.6 vs. 1.3; (2) pair of setae Vl 2 in male flagellum at same level of Dl3 vs. Vl2 proximal to Dl3 level; (3) spermathecae with basal contact between their lobes, while in C. bremensis are separated; distal semi-oval receptacula more thicker than stalk vs. receptacula of subequal thickness than stalk, and presence of sclerotized “duct” connect receptacula to ventral region of stalks vs. absence of sclerotized “duct”.
