The genus Monstera is represented in Colombia by 20 species, 12 of them from the Pacific slope of the Andes. Fieldwork between 2017 and 2019 in this region and a thorough revision of the main Colombian herbaria allowed us to discover two undescribed species belonging to Monstera section Monstera. The two new species are described and illustrated using color photographs of vegetative and reproductive features from living material, and compared to Monstera oreophila, M. epipremnoides and M. dissecta from Central America.

Pacific Species

The genus Platyrhina from the northwestern Pacific was reviewed, including a redescription and neotype proposal for Platyrhina sinensis (Bloch and Schneider 1801), and the description of two new species. Platyrhina limboonkengi Tang 1933 is relegated to the synonymy of P. sinensis, both species having two rows of hooked thorns on the mid-dorsum of the tail. Specimens previously widely identified as P. sinensis, but characterized by one row of such hooked thorns, represented an undescribed species, herein named Platyrhina tangi Iwatsuki, Zhang and Nakaya sp. nov. Platyrhina hyugaensis Iwatsuki, Miyamoto and Nakaya sp. nov., known from specimens limited primarily to the Hyuga Nada Sea, off Miyazaki, the Pacific coast of southern Japan, is similar to P. tangi in having one row of hooked thorns on the mid-dorsum of the trunk and tail, but differs in having larger hooked thorns, not encircled by light yellow or white pigment on the orbital, nape and scapular regions, and a pair of hooked thorns (absent in P. tangi) anteriorly on the scapular region. Nominal species are discussed and key to northwestern Pacific species of Platyrhina is provided.

During analysis of the benthic pycnogonid fauna of the Irish Sea collected by the HABMAP project, a specimen representing an hitherto undescribed species of the genus Sericosura was discovered, representing the shallowest record for the genus, and the first Atlantic record away from oceanic ridges. The new species, Sericosura conta, is more compact than the seven species previously described, and has a much shorter chelifore scape. It is the only species of Sericosura outside the Pacific Ocean to have a nine-articled palp. Three specimens of a second new species, Sericosura hedgpethi, were collected by NIWA from a cold-seep site on the Hikurangi Margin. This New Zealand species has a seven-articled palp, and, uniquely for the genus, is entirely without chelifora. The genus is reviewed, Ammothea verenae is reassigned to Sericosura, and an identification key to males and females of the nine known species is given.

Two New Species

Examination of a limited number of specimens of Leptoconops occurring in America indicates that at least several undescribed species exist in North and Central America and the West Indies. Paucity of material, however, prevents any detailed study of the group for the regions mentioned. Two members of the genus have, through their biting tendencies, made themselves decidedly obnoxious in the sections where they occur.

Aristolochia longissima and Aristolochia ornithorhyncha, two new species from the lowland moist forest from the Pacific watershed of southern Costa Rica and western Panama, are described and illustrated. Both species can be distinguished from most other species of Aristolochia series Thyrsicae, because of their leaves with pellucid gland dots, which are here documented in Aristolochiaceae for the first time. Comments about their distribution, habitat, phenology, conservation status and distinction from related species are provided. The circumscription of Aristolochia belizensis, A. chapmaniana, A. fragrantissima, A. ovalifolia, A. schmidtiana and A. tonduzii is discussed.

Two New Species

Thirty-eight species of Nepticulidae are known from the Yucatán Peninsula and adjacent areas (mainland Mexico and Be-lize). This paper describes two new species: Stigmella maya Remeikis & Stonis, sp. nov. (a leaf-miner of Karwinskia hum-boldtiana, Rhamnaceae), and Acalyptris yucatani Remeikis & Stonis, sp. nov. (a leaf-miner of Schinus sp., Anacardiaceae). S. maya is among the smallest Lepidoptera in the world. In its male genitalia S. maya resembles a sizeable group of undescribed species occurring in the Andes (Patagonia: Argentina). The adults of both new species are illustrated with photographs of adults, genitalia and leaf-mines.

Central Cordillera

Frequent biodiversity sampling and monitoring programs often lead to relevant taxonomic findings. Here, as a product of different field expeditions to two places in the northern Andes, we discover and describe two new species of rain frogs of the genus Pristimantis from the cloud forests of the Central Cordillera of Colombia. Pristimantis chocolatebari sp. nov. is diagnosed by having the following character states: dentigerous process of vomer triangular, snout large and protruding, dorsum smooth, vocal slits and vocal sac present, groin and hidden part of the thighs yellow. Pristimantis carylae sp. nov. is diagnosed by having iris copper red, dentigerous process of vomer oval, snout short and rounded, dorsum finely shagreen with scattered tubercles, double nuptial pad in males, groin and hidden part of thighs pink. We also infer, for the first time, the phylogenetic position of P. permixtus, P. platychilus, and two candidate new species. In addition, we emphasize not to use genetic distance as the only source of evidence for species delimitation, considering the high intraspecific diversity found in one of the species described here. Finally, we highlight the relevance of different habitat and ecosystem conservation strategies to promote amphibian diversity studies in the Andes.

Land Planarian

The Brazilian land planarians Cratera crioula, C. joia, Geoplana hina, and G. taxiarcha (Platyhelminthes, Tricladida, Geoplanidae) are revised taxonomically from type material and additional specimens. Geoplana hina sensu Carbayo et al. (2013) was found to be an undescribed species and therefore is described and named as Cratera picuia sp. n. A new species of the genus is also described and named as Cratera arucuia sp. n. G. hina and G. taxiarcha are transferred to Cratera. The most remarkable morphological feature of Cratera—a dilated terminal portion of the ejaculatory duct—is either absent, inconspicuous, or variable in C. hina, C. joia, C. picuia sp. n., and C. arucuia sp. n. Based on the monophyletic status of Cratera inferred elsewhere, an emendation of the genus is here proposed to encompass the morphological variation observed in the genus.

A New Species

The taxonomy and distribution of Pacific Annonaceae are reviewed in light of recent changes in generic delimitations. A new species of the genus Monoon from the Solomon Archipelago is described, Monoon salomonicum I.M.Turner & Utteridge sp. nov., together with an apparently related new species from New Guinea, Monoon pachypetalum I.M.Turner & Utteridge sp. nov. The confirmed presence of the genus in the Solomon Islands extends the generic range eastward beyond New Guinea. Two new species of Huberantha are described, Huberantha asymmetrica I.M.Turner & Utteridge sp. nov. and Huberantha whistleri I.M.Turner & Utteridge sp. nov., from the Solomon Islands and Samoa respectively. New combinations are proposed: Drepananthus novoguineensis (Baker f.) I.M.Turner & Utteridge comb. nov., Meiogyne punctulata (Baill.) I.M.Turner & Utteridge comb. nov. and Monoon merrillii (Kaneh.) I.M.Turner & Utteridge comb. nov. One neotype and four lectotypes are designated. The geographic patterns exhibited by nine native Annonaceae genera, that range in the Pacific beyond New Guinea, are discussed.
