“…The specimens were collected in 2014 in a small patch of tropical humid forest in the Puntarenas-Chiriquí biogeographical province. Morphology and DNA fragments (for the following markers: 18S rRNA, 16S rRNA, and cytochrome c oxidase subunit I) were examined, following Costa et al (2018Costa et al ( , 2021. The sequence data for three specimens were generated in previous phylogenetic studies (Costa et al, 2021;Giribet et al, 2018).…”

“…The standards for euthanizing, fixation, SEM protocols, and live specimen photography follow Monge-Nájera and Morera (1994) and Costa et al (2018); morphological descriptive nomenclature follows Read (1988a) and Oliveira et al (2010). Coloration was described from the photographs of the living specimens, following the standard names of the 267 Color Centroids of the NBS/ ISCC Color System (see Centore, 2016;Kelly, 1958).…”

“…Another important issue evidenced by these studies is the large number of undescribed species existent in the Neotropics. For example, in Brazil alone, 10 species have been described within the past decade (Brito et al, 2010;Costa et al, 2018;Oliveira et al, 2011Oliveira et al, , 2015, and many undescribed species are still known (Costa et al, 2021;Lacorte et al, 2011;Sampaio-Costa et al, 2009). Likewise, the onychophoran fauna of Costa Rica, another emblematic country for the study of Neotropical diversity, has been studied in detail and includes eight described species (Barquero-González et al, 2016, none of which extend to South America.…”

Among the least studied clade of velvet worms (Onychophora) is a clade of Neotropical Peripatidae (=Neopatida). Neopatida has been traditionally divided into an Andicoles group and a Caraïbes group, which now correspond to Oroperipatus and the remaining genera, respectively. Panama is located in a unique position bridging the faunas of both clades and of two large continents, both of which host an important diversity of velvet worms, yet taxonomic study of the Panamanian onychophorans has been largely neglected. In this study we critically evaluate the onychophoran diversity of Panama, redescribe a species from the former Canal Zone and describe a new species from the Pacific side, close to Costa Rica, as Epiperipatus bernali sp. nov., with a unique combination of characters visible under the SEM. We further discuss the existence of multiple lineages of Onychophora in Panama, both from the Andicoles and Caraïbes groups, and within the latter, with connections to different lineages, both from South and Central America.

“…In this decade, onychophorans were found in unexpected places, like Vietnam (Bai & Anh, 2012), lava tubes (Espinasa et al, 2015) and urban vegetation (Barrett, 2013), and the first model to explain and predict their survival in highly disturbed habitats, based on their size and habits, was published (Monge-Nájera, 2018). The only tropical African species was collected again after more than a century (Costa & Giribet, 2016), and the period was also marked by advances in the study of onychophoran genetics and conservation in Brazil (Lacorte, De Sena Oliveira, and Da Fonseca, 2011;Costa, 2016;Cunha et al, 2017;Costa et al, 2018).…”

Velvet worms, also known as peripatus or onychophorans, are a phylum of evolutionary importance that has survived all mass extinctions since the Cambrian period. They capture prey with an adhesive net that is formed in a fraction of a second. The first naturalist to formally describe them was Lansdown Guilding (1797-1831), a British priest from the Caribbean island of Saint Vincent. His life is as little known as the history of the field he initiated, Onychophorology. This is the first general history of Onychophorology, which has been divided into half-century periods. The beginning, 1826-1879, was characterized by studies from former students of famous naturalists like Cuvier and von Baer. This generation included Milne-Edwards and Blanchard, and studies were done mostly in France, Britain, and Germany. In the 1880-1929 period, research was concentrated on anatomy, behavior, biogeography, and ecology; and it is in this period when Bouvier published his mammoth monograph. The next half-century, 1930-1979, was important for the discovery of Cambrian species; Vachon’s explanation of how ancient distribution defined the existence of two families; DNA and electron microscopy from Brazil; and primitive attempts at systematics using embryology or isolated anatomical characteristics. Finally, the 1980-2020 period, with research centered in Australia, Brazil, Costa Rica, and Germany, is marked by an evolutionary approach: from body and behavior to geographic distribution; the discovery of how they form their adhesive net; the reconstruction of Cambrian onychophoran communities, the first experimental taphonomy; the first country-wide map of conservation status (in Costa Rica); the first model of why they survive in cities; the discovery of new phenomena like food hiding, parental feeding investment, and ontogenetic diet shift; and the birth of a new research branch, onychophoran ethnobiology. While a few names often appear in the literature, most knowledge was produced by a mass of researchers who entered the field only briefly.

Velvet worms, or onychophorans, include placental species and, as a phylum, have survived all mass extinctions since the Cambrian. They capture prey with an extraordinary adhesive net that appears in an instant. The first naturalist to formally mention them was Lansdown Guilding (1797-1831), a British priest from the Caribbean island of Saint Vincent. His life is as little known as the history of the field he initiated, onychophorology. This is the first general history of onychophorology, and I have divided it into half century periods. The beginning, 1826-1879, was defined by former students of great names in the history of biology, like Cuvier and von Baer. This generation included Milne-Edwars and Blanchard, and the greatest advances came from France, with smaller but still important contributions from England and Germany. In the 1880-1929 period, work concentrated in anatomy, behavior, biogeography and ecology, but of course the most important work was Bouvier’s mammoth monograph. The next half century, 1930-1979, was important for the discovery of Cambrian species; Vachon’s explanation of how ancient distribution defined the existence of two families; Pioneer DNA and electron microscopy from Brazil; and primitive attempts at systematics using embryology or isolated anatomical characteristics. Finally, the 1980-2020 period, with research centered in Australia, Brazil, Costa Rica and Germany, is marked by an evolutionary approach to everything, from body and behavior to distribution; for the solution of the old problem of how they form their adhesive net and how the glue works; the reconstruction of Cambrian onychophoran communities, the first experimental taphonomy; the first country-wide map of conservation status (from Costa Rica); the first model of why they survive in cities; the discovery of new phenomena like food hiding, parental feeding investment and ontogenetic diet shift; and for the birth of a new research branch, Onychophoran Ethnobiology, founded in 2015. While a few names appear often in the literature, most knowledge was produced by a mass of researchers who entered the field only briefly.
