The Quebrada Rambala drainage is found immediately south and south-southeast of the town of Chiriqui Grande and east of Rambala on the Caribbean coast. It is one of two tributaries of the Rio Margarita watershed, a small, lowland drainage with elevations up to 180 m. During the 2014-2017 period, collections of caddisflies (Insecta: Trichoptera), employing both UV-light and Malaise traps, were made at two locations on Quebrada Rambala proper, and four locations on its unnamed tributary, all on a land area of approximately 1 ha. As a result, 127 species of caddisflies were identified, including 59 species of microcaddisflies. A non-parametric estimator of true, or potential, species richness based on rare species present for this watershed is 211 species. Previously, 19 new country records were published from this location. In this paper, we record three additional country records (Hydrobiosidae: Atopsyche minimajada Blahnik and Gottschalk; Hydroptilidae: Leucotrichia rhomba Thomson and Holzenthal and Oxyethira (Oxytrichia) apinolada Holzenthal and Harris) and describe and illustrate 19 new species of microcaddisflies (Alistotrichia bernali, Cerasmatrichia blahniki, Costatrichia santosi, Metrichia macdonaldi, M. thomsonae, M. thurmani, M. trebeki, Neotrichia carlsoni, N. rambala, N. serrata, N. starki, Ochrotrichia birdae, O. dewalti, O. kondratieffi, Oxyethira buenoi, Rhyacopsyche holzenthali, Tizatetrichia panamensis, Zumatrichia flinti, and Z. hazelae). Combined, this one small portion of the Quebrada Rambala has increased Panama’s caddisfly fauna by 41 species of microcaddisflies. Additionally, several new species of macrocaddisflies await description. Finally, we add one new genus to Panama’s fauna (Hydroptilidae: Tizatetrichia Harris, Flint, and Holzenthal). With the publication of these new taxa, Panama’s caddisfly fauna now includes 403 species in 15 families and 53 genera. We also suggest that multiple collections over time for all stream orders, employing several collection methods, are required in order to better estimate species richness within a drainage.
Description of three new species of Caledomina (Insecta, Trichoptera, Ecnomidae) from New Caledonia
(2017)
Three new species of Caledomina Johanson, 2011 are described and illustrated for the first time: C. paniensis sp. nov., C. dorsospina sp. nov. and C. kohensis sp. nov. A key to the males of the four known species in the genus is given, as well as a map indicating their geographical distribution. When examining a phylogenetic hypothesis comprising the four species, we see an increased complexity in younger species compared to older species.
The Chimarra lehibemavo species-group, new and endemic to Madagascar (Trichoptera, Philopotamidae)
(2017)
The Chimarra lehibemavo group is described to include thirteen new species: Chimarra lehibemavo sp. nov., C. cebegepi sp. nov., C. fenoevo sp. nov., C. forcellinii sp. nov., C. fotobohitra sp. nov., C. gattolliati sp. nov., C. gensonae sp. nov., C. jejyorum sp. nov., C. hamatra sp. nov., C. makiorum sp. nov., C. moramanga sp. nov., C. saha sp. nov. and C. tamara sp. nov. The adults are easily recognizable by their large size, yellow colour and the structure of the male genitalia. The membranous tergum IX and the absence of the mesal lobe of tergum X are observed in other lineages, but the strong asymmetrical deformation of the phallotheca is apomorphic. The group is monophyletic with unknown affinities, but a preliminary phylogenetic placement is suggested following genetic analysis of two specimens. With one exception, the species have restricted geographical distributions in Madagascar and inhabit rivers in eastern pristine rainforests.
