Figures 14–16, 22 (in part). Table 5.  
 Type locality: Colombia, Nariño.   
 Type material: Holotype (male): COLOMBIA: Nariño: Barbacoas: km 95 via Tumaco-Pasto, Reserva Natural Biotopo (1°23´00´´ N; 78°15´00´´W): Rain Forest, 500 masl, 14 September 2009, D, Martinez, H. Herreño, manual collection, male (ICN-Am-108). Paratypes (1 female, 1 male): COLOMBIA: Nariño: Barbacoas: km 95 via Tumaco-Pasto, Reserva Natural Biotopo (1°23´00´´ N; 78°15´00´´W): Rain Forest, 500 masl, 14 September 2009, D, Martinez, H. Herreño, manual collection, male (ICN-Am-108); Vereda Altaquer (1°14´45.60´´ N, 78°06´55.12´´W): on the ground, April 15 of 2010, 1270masl, manual collection, female (ICN-Am-75).   
 Distribution: Colombia, Nariño.   
 Etymology: This species is dedicated to the Colombian native community Awá (Kwaiker or Awa-Kwaiker), which inhabit between the boundaries of Colombia and Ecuador, and some they settle in the type locality (Nariño). We consider that this species deserves to be considered as part of his natural richness. Name in apposition.   
 Diagnosis. Heterophrynus awa sp. nov. can be differentiated from other species by present the following characters together: four teeth in the ectal portion of the basal segment of the chelicerae. Five long spines in the ventral femur, spine FIII is smaller than FII and FV, FIV is small, presents a small spine PVI.   
Female genitalia with gonopod sclerites elongated and with laminar shape, a medial portion wider than the basal and distal portion, distal portion thick and with a rounded apex. Seminal receptacles oval with a sclerotized area at the base (Fig. 16D).  
 Similar species: This species is similar to H. alces but it presents a small spine TIII and T3, which is absent in H. awa sp. nov. and the female genitalia is completely different, presenting the sclerites of the gonopods with a rounded shape. The species H. armiger is very similar, however, it presents female genitalia with sclerites not widened at the medial portion, and with an acuminated apex (Fig. 6D).   
 The male genital of H. armiger and H. awa sp. nov, presents Pi rounded and so smaller than the LaM, the LoL 1 has a similar length with the LaM. Both species differ because H. armiger presents a spine on LOL 1 which is absent in H. awa sp. nov (Fig. 6A, B, C; 7; 16A, B, C).   
 Description. Male (ICN-Am-108): Total length 20.9 mm. Carapace, opisthosoma, and legs have a brown coloration, with red tonalities, pedipalps brown. Measures of the male are provided in Table 5.   
 Carapace. Anterior margin straight without lobes, carapace surface with a widely spaced granulation, posterior margin with a concave area in the medial region. Lateral and anteromedial eyes clearly visible, anteromedial ocular tubercle with black coloration (Fig. 14A).   
 Sternum. Tri-segmented, segments are well sclerotized, the area around segments is also sclerotized. Tritosternum projected anteriorly, elongated, conical, with more than 10 setae in the basal region, five in the medial region three in distal region and two more in the apex.   
The second segment (tetrasternum) rounded and with four setae; two on the medial region and two on the apical region. The third segment (pentasternum) rounded, smaller than the second segment, has two setae on medial region. Metasternum longitudinally divided with two setae in each segment (Fig. 14B).  
 Abdomen. Oblong, color brown, with soft punctuations, and darker areas in the medial area of the sclerites. Carapace wider than the Abdomen (Fig. 14C).   
 Chelicera. Presents a mesal row of three teeth on the basal segment of the chelicerae with the first in the proximal region, with two cuspids, follow by one tooth shorter in the medial portion, and the third bigger than others placed in the distal region (Fig. 14D). The ectal row of the basal segment of the chelicerae have four conspicuous teeth, two with acuminated apex placed in the proximal and medial portions (tooth 1 and 2), and two with acuminated apex placed on the medial portion (tooth 3 and 4) (Fig. 14F). Mobile finger of the chelicerae with five teeth.   
 Pedipalp. Trochanter: Prolateral face with four spines; spines Tr1 and Tr3 placed in the medial region, Tr2 placed near to ventral margin. Tr3 and Tr4 with subequal lengths. Spines lengths: Tr2>Tr1>Tr4≥Tr3. Dorsal oblique series of six setal tubercles. The dorsomedial area without spines but with one tubercle (Fig. 14E). Femur: Ventral face with five major spines, there are three tubercles between FII–FIII, one small spine FIV with two tubercles at each side between FIII–FV, a small spine with three tubercles at each side between FV–FVI, ten tubercles more distally than FVI, FIV has almost the size of a tubercle. Spine lengths: FI>FII>FV>FVI>FIII>FIV (Fig. 15A). Dorsal face with five major spines, there are three tubercles between F2–F3, a very small spine and four tubercles between F3–F4, two very small spines and three tubercles between F4–F5, and eight tubercles more distally than F5, F1 and F2 are joined at the base, F3 clearly separated from F2. Spine lengths: F3>F4>F1=F2>F5 (Fig. 15B). Patella: Ventral face with six major spines, presents a small PVI, there are three tubercles more proximally than PVI, one small spine and three tubercles between PVI–PV, four tubercles between PV–PIV, and PIV–PIII, three tubercles between PIII–PII and five between PII–PI, PI wider than the other spines. Spine lengths: PIV>PII>PV>PI>PIII>PVI (Fig. 15C). Dorsal face with six major spines, seven tubercles between P6–P5, P7 is absent. Spine lengths: P3=P4≥P5>P6>P1>P2 (Fig. 15D). Tibia: Ventral face with two major spines. Spine lengths: TII>TI (Fig. 15E). Dorsal face with two major spines. Spine lengths: T2>T1 (Fig. 15F). Tarsus-metatarsus: Internal face with the secondary line of dorsomedial bristles complete, the suture between the tarsus and the apotele is not visible. Legs. Femora brown. Femora lengths: I>III>II>IV (Table 5). Leg I: Tibia with 31 segments and tarsus with 70 segments in the right and left leg. Leg IV: Basitibia with three segments.   
Basitibia-distitibia lengths: BT1>DT>BT3>BT2. Basitarsus as long as the telotarsus. Tarsus tetramerous.  
  Female genitalia (ICN-Am-75):  Genital operculum pentagonal, reaching the second segment of the opisthosoma, seminal receptacles with an oval shape, completely separated at the medial portion, dorsal surface sclerotized at the proximal region, with brown coloration, medial and distal portion white. Sclerites with laminar shape, the medial region is wider than the basal and distal region, distal portion a little curved and thinner than the basal portion, with rounded apex, sclerites placed parallel, longer than the width of the seminal receptacle, sclerites longer than the total length of the seminal receptacle (Fig. 16D).   
 Variation. Variation in measures and segments of the basitibia IV, Tibia I and tarsus I, are provided in Table 5.   
  Sternum.  The number of setae over all segments of the sternum was variable. Pedipalp. Trochanter: line of setal tubercles vary between five and six. Femur: Ventral face: FIV can be present as a spine or tubercle, number of tubercles between spines is variable, and can be more conspicuous. Dorsal face: number of tubercles between spines is variable, tubercles can be more conspicuous. Patella. Ventral face: relative size between PI and PIII is variable, number and size of small spines and tubercles between major spines are variable. Dorsal face: number of tubercles are variable. Legs. Leg I: Number of segments of tibia vary between 31 and 33 and in the tarsus between 66 and 76, the relative size of femora is variable (Table 5).   
 Male. Observed Males were bigger than females (Table 5). Spination pattern same as females. Genital operculum has an oval posterior margin, expanded to the third segment of the opisthosoma.   
  Male genitalia.  (ICN-Am-108): LaM longer than Pi. LoL 1 longer than LoL 2, LoL 1 is wider, densely covered with minute projections, placed close together with the base not visible; LoL 2 is wrinkled and does not present projections. In dorsal view, the LoD are, long, rounded and do not cover LoL1 and LoL 2 (Fig. 16A, B, C).
