Especies descubiertas en Chucantí

This was the first Strophaeus species and only the second from the family Barychelidae known from Panama. Due to limited information, direct comparisons between S. sebastiani and related species were difficult. However, this group is known to have high rates of endemism. The wide geographic separations among S. sebastiani and its relatives was enough to consider it a new species (other Strophaeus species occur in Brazil and Peru). It was named in honor of Sebastián Miranda, son of the first author of the describing paper for this species.

This species builds "trap-door" shelters similar to those of related species. The original specimens were found in open areas ~800 m above sea level. This species is currently only known from Cerro Chucantí, where it may be endemic.

A long (~9.3 mm) cerambycid with completely divided eyes. Distinguished from other species in its genus by its orange pronotum with a dark central line and orange-tipped antennae. The first Tessaropa species described from Central America, this species was named in honor of Elizabeth Anne Bezark, daughter of the first author of the describing paper, who “has been known to collect a cerambycid or two from time to time”.

Known to occur at 875 m above sea level at Cerro Chucantí, where it may be endemic. The original specimens were collected after being attracted to white light.

A long salamander with completely webbed feet, B. chucantiensis belongs to the most diverse genus of salamanders worldwide. Its top color varies from dark brown to reddish (Figure 1), sometimes with patches of gold speckling.

Lives in understory foliage in eastern Panamanian montane forest ~1,400 m above sea level. It has been found active at night on leaves a few meters above the ground, usually shortly after rain. This species is currently only known from Cerro Chucantí, where it was found (thus the specific name, chucantiensis) and is considered endemic.

B. chucantiensis has been listed as Critically Endangered [CR] by the International Union for the Conservation of Nature (IUCN) since 2019 due to its small known distribution (~2 square kilometers) and local threats from agriculture and logging.

Although not yet evaluated by the International Union for Conservation of Nature (IUCN), the authors of the describing paper for this species have suggested it should be considered Critically Endangered [CR] due to its small geographic distribution. When it was described, T. berguidoi was determined to have the highest environmental vulnerability score of any species of Tantilla.

Identification

The coloration of this species (having pale lateral and mediodorsal stripes on a dark background and a head with a pale neck collar) places it in the reticulata section of the taeniata group.

The following describes the male, female not yet described.

A small, thin snake (~40.8 cm long) with a head slightly broader than its body. The dark cap on its head is separated from the rest of the body by a faint pale collar. Body striping is important for identification:

• Pale brown mediodorsal stripe restricted to the middle half of the mediodorsal scale row, bordered on either side by a dark dorsolateral stripe ~2.5 scales wide.
• Dark ventrolateral stripe 2.5 scales wide present in scale rows 1, 2, and the first portion of row 3.
• Dark dorsolateral and ventrolateral stripes are separated by a pale brown stripe 2 scales wide.

Habitat and distribution

Eastern Panamanian montane forest > 1,000 m above sea level. This species is currently only known from Cerro Chucantí, where it is considered endemic.

Biology and natural history

Apparently active year-round in leaf litter on the forest floor. A secretive and rarely encountered species, T. berguidoi may be primarily nocturnal (most individuals observed to date were found at night).

Etymology

This species received its name in honor of Guido Berguido, founder of ADOPTA and the Cerro Chucantí Private Nature Reserve.

Due to its restricted range and threats from local agriculture and logging, the authors of the describing paper for this species have suggested A. annularum should be considered Critically Endangered [CR].

Identification

A hemiepiphytic climbing herb with stems to 1 m long. The swollen, ring-shaped structures at the internodes are a defining characteristic.

Foliage is lance-shaped, green and semi-glossy. Flowering structure has a reddish stem 1.5 - 3.5 cm long; small, green or whitish green spathe; and erect, yellowish green spadix up to 1.9 cm long. Flowers have whitish anthers, 3 - 4 visible on main spiral and 2 - 3 on the alternate spiral. Fruiting structure hanging, with a spathe that tends to fall off; spadix larger than when flowering; flowers turning reddish-purple. Berries round, light green to greenish white, a portion eventually turning translucent, containing 1 - 2 seeds.

Habitat and distribution

Canopy of premontane wet forest/tropical wet forest ~1,325 m above sea level, in habitats dominated by Quercus, Sloana, Oreomunnea, and Magnolia species. This species is currently only known from Cerro Chucantí, where it is considered endemic.

Biology and natural history

Notable for growing 25 - 30 m above the ground in the canopy, together with various species of orchids.

Etymology

Specific name is from the Latin "annularis", meaning ring-like, in reference to the ring-shaped swellings at the nodes of this plant.

A large herb resembling a banana plant, but with a long (to 220 cm) hanging flowering structure. The specific coloration of the flowering structure – red with golden hairs, containing pink flowers – is unique to this species. It was named in honor of Guido Berguido, founder of ADOPTA and the Cerro Chucantí Private Nature Reserve.

Grows in mature and regenerating secondary premontane forest around 800 - 900 m above sea level. This species is currently only known from Cerro Chucantí, where it is considered endemic. The authors of the describing paper for this species have suggested it should be considered Critically Endangered [CR] because of its small distribution (estimated at 4 km2) and threats from local agriculture and logging practices.
