Distribution: Colombia, Brazil.

Etymology: This species is dedicated to the biologist Andrés Sánchez also known as “Origami”, which collected the first exemplar of this species in Colombia. Besides being an excellent entomologist, and friend, he is a virtuous in the art of origami, to which he owes his pseudonym.

Diagnosis. Heterophrynus origamii sp. nov. can be differentiated from other species by present the following characters together: three teeth in the ectal portion of the basal segment of the chelicerae. Five long spines in the ventral femur, spine FII is smaller than FIII and FI, FIII longer than FV, FIV is absent. Female genitalia with a sclerite of the gonopod elongated with a medial portion wider, a constriction between the medial and distal portion, apex rounded and wider than the basal portion. Seminal receptacles are rounded, with a sclerotized area that covers only the basal part ( Fig. 19D View FIGURE 19 ).

Similar species: This species is similar to H. batesii , H. caribensis and H. longicornis , this three species, together with H. origamii sp. nov., present almost the same pattern of spines in the pedipalp; however, the female genital has visible differences, in H. batesii and H. caribensis the sclerite of the gonopod is laminar and uniform, without a wider medial portion, or constrictions near to the apex. Almost in all adult specimens of H. batesii and H. caribensis , the sclerite is completely red without white regions, in contrast with H. origamii sp. nov. Seminal receptacles are more rectangular and elongated in H. batesii and H. caribensis , as well as the sclerites, are longer ( Fig. 20D View FIGURE 20 ). Heterophrynus longicornis has a sclerite of the female gonopod with a base more than two times wider than the medial and distal portion and presents a very strong curvature at the medial portion ( Fig. 21D View FIGURE 21 ), this sclerite is completely different with the one of H. origamii sp. nov.

The male genital of H. batesii , H. caribensis , H. longicornis and H. origami sp. nov. are characterized by having a Pi thin and elongated, but smaller than the LaM; the LaM has a similar length with the of LoL 1 and 2 together ( Fig. 19A, B, C View FIGURE 19 ; 20A, B, C View FIGURE 20 ; 21A, B, C View FIGURE 21 ); it differs from the other evaluated species, however, male genital of this four species is almost equal.

Description. Female (MZUSP 68451): Total length 18.5 mm. Carapace, opisthosoma, pedipalps, and legs have a brown coloration, with red tonalities. Measures of the female are provided in Table 6. Posterior margin of carapace with a concave medial region. Lateral and anteromedial eyes clearly visible, anteromedial ocular tubercle with black coloration ( Fig. 17A View FIGURE 17 ).

Sternum. Tri-segmented, segments are well sclerotized, the area around segments is also sclerotized. Tritosternum projected anteriorly, elongated, conical, with 24 setae in the basal region, two in the medial region, two in distal region and two more in the apex.

The second segment (tetrasternum) rounded and with four setae, two in the basal region and two in the medial 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. 17B View FIGURE 17 ).

Abdomen. Oblong, color brown with red tonalities, with soft punctuations. Carapace wider than the Abdomen ( Fig. 17C View FIGURE 17 ).

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, followed by one tooth shorter in the medial portion, and the third bigger than others placed in the distal region ( Fig. 17D View FIGURE 17 ). The ectal row of the basal segment of the chelicerae have three conspicuous teeth, two with acuminated apex placed in the proximal and medial portions (tooth 1 and 2), and one with acuminated apex placed on the medial portion (tooth 3) ( Fig. 17F View FIGURE 17 ). Mobile finger of the chelicerae with four teeth.

Pedipalp. Trochanter: Prolateral face with four spines; spines Tr1 and Tr3 placed in the medial region, Tr2 placed near to ventral margin. Spines lengths: Tr2>Tr4>Tr3≥Tr1. Dorsal oblique series of seven setal tubercles. The dorsomedial area without spines but with one tubercle ( Fig. 17E View FIGURE 17 ). Femur: Ventral face with five major spines, spine FIV is absent, there are three tubercles between FI–FII, four between FII–FIII, five between FIII–FV, eight tubercles between FV–FVI, and six tubercles more distally than FVI. Spine lengths: FI>FIII>FII>FV>FVI ( Fig. 18A View FIGURE 18 ). Dorsal face with six major spines, there are three tubercles between F2–F3 and F3–F4, five between F4–F5 and F5–F6, and six more distally than F6, F1 and F2 are joined at the base, F3 clearly separated from F2. Spine lengths: F3>F4>F1=F2>F5>F6 ( Fig. 18B View FIGURE 18 ). Patella: Ventral face with six major spines, there are two tubercles more proximally than PVI, three between PVI–PV, five between PV–PIV, four between PIV–PIII, three between PIII–PII, and three between PII–PI, PI wider than the other spines. Spine lengths: PIII>PIV>PII>PV>PI>PVI ( Fig. 18C View FIGURE 18 ). Dorsal face with seven major spines, four tubercles more proximally than P7, six between P7–P6, five between P6–P5, four between P5–P4, and P4–P3. Spine lengths: P3=P4>P5>P6>P1>P2>P7 ( Fig. 18D View FIGURE 18 ). Tibia: Ventral face with two major spines, with one tubercle between TI–TII. Spine lengths: TII>TI ( Fig. 18E View FIGURE 18 ). Dorsal face with two major spines. Spine lengths: T2>T1 ( Fig. 18F View FIGURE 18 ). 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>II>III>IV ( Table 6). Leg I: Tibia with 39 segments and tarsus with 89 segments in the right leg; in left leg ha 39 segments in the tibia and 88 segments in the tarsus. Leg IV: Basitibia with three segments.

Basitibia-distitibia lengths: BT1>DT>BT3=BT2. Basitarsus as long as the telotarsus. Tarsus tetramerous.

Female genitalia. Genital operculum pentagonal, reaching the second segment of the opisthosoma, seminal receptacles with a rounded shape, completely touching to each other at the medial portion, dorsal surface sclerotized only at the proximal portion, with orange coloration, medial and distal portion white. Sclerites elongated with a medial and distal portion wide, present a constriction between medial and distal portion, distal portion wider than the basal portion, with rounded apex, sclerites placed opposite to each other, shorter than the width of the seminal receptacle, the sclerite of the gonopod cover the half of the length of the seminal receptacle, present a brown-orange coloration with a white area at the base ( Fig. 19D View FIGURE 19 ).

Variation. Variation in measures and segments of the basitibia IV, Tibia I and tarsus I, are provided in Table 6. Sternum. The number of setae over all segments of the sternum was variable. Pedipalp. Trochanter: line of setal tubercles vary between six and eight. Femur: Ventral face: more distally than FVI can be present one or two spines so much smaller than the others are. Dorsal face: spine F6 can be more conspicuous. Patella . Dorsal face: P7 can be as long as P2. Female genital. in the sclerites of the gonopod, the brown coloration and white coloration is variable, in some cases brown coloration can cover a bigger or smaller portion of the sclerite. Chelicerae. Mobile segment: the number of teeth can be variable.

Male. Observed Males are as big as females ( Table 6). Spination pattern same as females. Genital operculum has an oval posterior margin, expanded to the third segment of the opisthosoma.

Male genitalia. (MZUSP 54589): 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 winkled and does not present projections. In dorsal view, the LoD are rounded very long and covering LoL1 and LoL 2 ( Fig. 19A, B, C View FIGURE 19 ).
