Type material. Holotype: COLOMBIA, Quindio: adult male from Bosque de Bremen (Bremen Forest), Filandia municipality, 1908 m.a.l.s., 04°41’03.9”N 75°37’34.1”W, daylight manual capture, under rotten log, 30. VI.2011, J.A. Moreno-González (MUSENUV- 23527). Paratypes: one adult female (MUSENUV- 23528) and one juvenile (MUSENUV- 23529) same data as holotype; one adult female (spermathecae damaged during dissection) same locality data as holotype, 1991 m.a.l.s, 04°41’15.8”N 75°37’31.2”W, Winkler Trap, 2.VII.2011, J. A. Moreno- González (ICN-ASc-046).
Etymology. The name is an adjective based on the type locality Bosque de Bremen (Bremen Forest) (Filandia municipality, Quindío department, Colombia) where the species was collected.
Diagnosis. Total length 3.31–3.86 mm (flagellum not included). Male flagellum 1.3 times longer than wide and 4 times longer than pedicel length, with setae Vl2 proximal to Dl3 level. Spermathecae with one pair of lobes whose bases are separated; with rounded receptacula of subequal thickness than stalk; sclerotized “duct” absent.
Description. Male holotype (Figs 1–2). Coloration: general pattern dark greenish-brown. Chelicerae reddish and flagellum light brownish. Pedipalps: trochanter light reddish-brown; femur and patella dark greenish-brown; tibia almost reddish, dark reddish-brown distally and light greenish-brown basally; tarsus reddish-brown. Legs: coxae I–IV, anterior and posterior sterna light reddish; trochanters I–IV light greenish-brown; femora I–IV dark greenish-brown; patellae I–IV light greenish-brown; tibiae II–IV light greenish-brown, except for tibia I that is reddish-brown; all tarsus light reddish-brown.. All body setation dark reddish-brown.
Prosoma (Fig. 1). Anterior process of propeltidium with 2 setae (one behind the other) follow by 3 pairs of dorsosubmedian setae; eyespot suboval; metapeltidium entire. Anterior sternum with 3+8 setae and posterior sternum with 6 setae.
Opisthosoma (Figs 1–2) 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.
TABLE I. Measurements (mm) of Calima bremensis gen. and sp. nov. and C. valenciorum gen. and sp. nov. Flagellum (Figs 3 – 8) Dorsoventrally flattened, sub-rhomboidal shaped and short, 1.3 times longer than wide and 4 times longer than pedicel length. Setation: Vm1 at same level as Dm1; pair Vm2 absent; pair Vm4 proximal to Dl1 level; Dl1 positioned proximal to V l1; Vm 5 proximal to Dm4; Vl2 proximal to Dl3 level. One pair of lateral microsetae at Vm1 level; 1 pair between Dm1 and Dl1, and 1 irregular “patch” composed of 6–9 microsetae since level Vm 5 to V l2. With one pair of dorsosubmedian depressions between Dl1 and Vm5; without any dorsal swelling.
Chelicerae (Figs 9 – 10). Movable finger (Fig. 9) sharp and curved distally, serrula, composed of 21 hyaline teeth (2 small and 19 large), increasing in size towards distal region, guard tooth elongated. Lamella bicuspid and small. Fixed finger (Fig. 10) with 6 similar sized teeth between 2 large outer teeth. Setation: G1 (setae group 1) with 3 spatulate setae, 1 (most dorsal) with basal surface almost smooth, other 2 with basal surface covered 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 8 similar sized feathered setae and G6 with 1 smooth setae longer than half of movable finger length. Setal group formula: 3-5-4-2-8-1.
Pedipalp (Fig. 11). 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, 1.6 times longer than high, dorsal edge 5 times longer than ventral edge, thinner at base and wider at apex, lateral external surface with 2 large setae and 2 small setae. Patella: cylindrical, 2.2 times longer than high, distal edge 1.3 times longer than basal edge of segment, with at least 2 rows of dorsal setae, 1 row on lateral and 2 rows on ventral. Tibia: cylindrical, 3 times longer than high, base as high as patella; thin and longer than patella, with at least 2 ventral, 1 lateral, 2 dorsal, and 3 ventral rows of setae. Tarsus: conical, 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- 23528). Coloration (Figs 12 – 13) and setation same as male, only differing in sternites I–II setae which have 4 rows of microsetae.
Flagellum (Figs 14–19). With 4 segments, 6 times longer than wide. Segment II with Dm1 and Vm1 present, Vm2 absent. Segment III with Vm4 and with Vm4 and 1 lateral pair of microsetae. Segment IV with Vl1 proximal to Vm5 and Dl1; Dl1 between level of Vl1 and Vm5; Dm4 between Dl1 and Dl3; Vl2 proximal to Dl3 and distal to Dm4, 1 pair of distolateral microsetae present above Vl2.
Chelicerae (Fig. 20). Similar to male, serrula composed of 19 hyaline teeth (1 small and 18 large) increasing in size towards distal region. Guard tooth elongated. Lamella small with one cusp present; setation similar to male, except for setal group formula 3-5-4-2-10 -1.
Pedipalp (Fig. 21). Simple, similar to male.
Spermathecae (Fig. 22). Consists of 1 pair of lobes, with thick stalks “C”-like curved, whose bases are separated; with apex directed to median region; stalks with distinct terminal large rounded sclerotized bulbs (receptacula) of subequal thickness than stalk with a basal membranous rounded eminence pronounced dorsally; sclerotized “duct” absent; ventral region of receptacula cover with numerous duct openings; chitinized arch barely evident and slightly developed, only with their lateral triangular points strongly sclerotized; gonopod absent.
Distribution (Fig. 42). This species is only known from the type locality, located in the central Colombian Andes.
Natural History. In four field trip days, only four individuals (three adults and one juvenile) were collected, all inside and under rotten logs or humus. A juvenile (presumably of the same species), was found near several galleries of an indeterminate species of Rhinotermitidae inside of a rotten log. The Bosque de Bremen (Bremen Forest) is a restored forest (Figs 43–44), comprising a biological corridor connected to Bosque del Cañon del río Barbas (Forest of Barbas river canyon), with a highway crossing through it.
