Heterophrynus boterorum

Description of female (holotype): Carapace (Fig. 4 a): flattened, wider than long; prominent eyes, median eye tubercle dark-brown, without apical setae, lateral eye tubercle smaller, with around half its size. Margin of carapace entirely with sinuous lines and coarse granules, anterior margin in a very smooth, practically straight curve. Overall densely covered by small granules mostly anteriorly, bundles of bigger and more sparse granules departing from the fovea towards the border. Frontal process well-developed, with greatly widened base and abruptly getting thin in distal half, ending in a very acute hook, not exceeding front line of carapace, this way not visible in dorsal view. Sternum (Fig. 4 b): Tri-segmented, typical of Phrynidae. Tritosternum extremely long projecting between pedipalp coxae, reaching almost half of their length. Covered with bristles on its entire length, from apex to base, with an increase in the density at base. Mesosternum convex, reduced to a small tubercle, ranging from slightly oblong to sharply oblong, with six to eight bristles. Metasternum is a small convex mound with two bristles Abdomen (Figs. 4 a – b): oblong, with almost indistinguishable punctuations, thinner than in the carapace. Chelicera: Cheliceral furrow (Figs. 6 a – b) with 3 internal teeth, the distal one bifid, the first cusp bigger than the second one II IIIb. The third tooth (middle) much smaller than the others. With 3 external teeth, the distal one bifid, the first cusp bigger than the second one II> I = IIIa> IIIb. Claw with five denticles, with the two distalmost much reduced, the second smaller than first and third. Pedipalp: Trochanter (Figs. 4 c – d): with well-developed retro-ventral apophysis, armed with four spines, the one adjoining the retro-ventral apophysis is the largest, but not more than twice the size of others, which are subequal. The biggest spine is of comparable size to the fourth ventral spine of pedipalpal femur. Femur (Figs. 4 c – d): three dorsal spines in the main series (1> 2> 3), the first one three times bigger than the last one; prominent geminate spines before the first spine, the dorsalmost subequal to spine 2 and the other subequal to spine 3; four ventral spines (1> 2> 3> 4) of approximately the same length of the dorsal ones; one spine placed proximally to the first one, which is located more interiorly than the main series of spines, with a similar length of the third one, but less robust; last spine ½ the length of the first one. Tibia (Figs. 4 c – d): six spines, main series with four spines (I = II = III> IV); two accessory spine anterior to spine I, with its length similar to spine IV; five ventral spines (III> IV> II> I> V), Basitarsus (Figs. 4 c – d): two dorsal spines and two ventral spines dorsal distal> dorsal basal = ventral distal> ventral basal. The distal dorsal spine subequal to the claw. Claw (Figs. 4 c – d): long, with an acute, curved tip. The males do not exhibit considerable secondary sexual dimorphic features, and the pedipalps of males and females are of comparable size. Legs: All densely setose. Ventral corner of the prolateral face of femora II – IV projecting in a distinct spiniform process. Femur length I> III> IV> II. Tibia I with 35 pseudoarticles and tarsus (basitarsus + distitarsus) I with 79 - 80 pseudoarticles in both legs. Leg IV: (Fig. 6 c): Basitibia: 4 pseudoarticles, one trichobothrium at the first and one at the last pseudoarticle. Distitibia: 16 trichobothria. Basitibia-distitibia length BT 1> DT> BT 3 = BT 4> BT 2. Distitarsus: with 3 pseudoarticles. Measurements. Females (n = 1): Total body length: 23.0, Cephalothorax: Length: 8.0 mm, Width: 10,5 mm. Abdomen: 13.0 mm. Pedipalp: Femur 9.0 mm, Tibia 10.0 mm, Tarsus 5.0 mm, Tarsal claw 3.5 mm. Males (n = 1): Total body length: 24.2, Cephalothorax: Length: 10.0 mm, Width: 11,0 mm. Abdomen: 17.0 mm. Pedipalp: Femur 11.0 mm, Tibia 14.5 mm, Tarsus 5.1 mm, Tarsal claw 4.0 mm. Color pattern (in alcohol): Chelicerae, pedipalps, legs and carapace reddish-brown. Coxae and ventral surface of abdomen lighter colored. Genitalia: Male (Figs. 5 a – f). PI longer than LaM. LoL 1 and LoL 2 subequal in length, both densely covered with minute denticles (but larger than in H. silviae). In dorsal view the LoD is subequal in size to LoL 1. Female. (Fig. 6 d) Gonopod claws bifid. Inner branch probably arising from basal third of claw complex. Natural history. The specimens described were collected on rocks and ravines in a fragment of Andean montane secondary forest in a very disturbed area surrounded by coffee plantations and rural residential areas.
