The Trichoptera of Panama XXII. Sixteen new microcaddisfly species (Trichoptera, Hydroptilidae).

ABSTRACT: Sixteen new species of microcaddisflies (Trichoptera, Hydroptilidae) from Panama are herein described and illustrated. The majority of these were collected during surveys of Panama's national parks and protected areas during 2017 and 2018, employing both UV and Malaise traps. The new species include: Alisotrichiaeisbergaesp. nov., Angrisanoiabokotasp. nov., Brediniaparaespinosasp. nov., Cerasmatrichiagarfiozasp. nov., Cerasmatrichiaveraguasensissp. nov., Costatrichiacaloveborasp. nov., Metrichiacaloveborasp. nov., Metrichiacascadasp. nov., Metrichiachiriquiensissp. nov., Metrichiaescobillasp. nov., Metrichialeahaesp. nov., Metrichiatatianaesp. nov., Ochrotrichiaconejorejasp. nov., Ochrotrichiaparaflagellatasp. nov., Oxyethirapehrssonaesp. nov., and Zumatrichiaculebrasp. nov. In total, 506 Trichoptera species are now recorded for the Republic of Panama, distributed among 15 families and 56 genera.

Project description:Metrichia is assigned to the Ochrotrichiinae, a group of almost exclusively Neotropical microcaddisflies. Metrichia comprises over 100 described species and, despite its diversity, only one species has been described from Brazil so far. In this paper, we provide descriptions for 20 new species from 8 Brazilian states: M. acuminata sp. nov., M. azul sp. nov., M. bonita sp. nov., M. bracui sp. nov., M. caraca sp. nov., M. circuliforme sp. nov., M. curta sp. nov., M. farofa sp. nov., M. forceps sp. nov., M. formosinha sp. nov., M. goiana sp. nov., M. itabaiana sp. nov., M. longissima sp. nov., M. peluda sp. nov., M. rafaeli sp. nov., M. simples sp. nov., M. talhada sp. nov., M. tere sp. nov., M. ubajara sp. nov., and M. vulgaris sp. nov. DNA barcode sequences (577 bp of the mitochondrial gene COI) were generated for 13 of the new species and two previously known species of Metrichia resulting in 64 sequences. In addition, COI sequences were obtained for other genera of Ochrotrichiinae (Angrisanoia, Nothotrichia, Ochrotrichia, Ragatrichia, and Rhyacopsyche). DNA sequences and morphological data were integrated to evaluate species delimitations. K2P pairwise distances were calculated to generate a neighbor-joining tree. COI sequences also were submitted to ABGD and GMYC methods to assess 'potential species' delimitation. Analyses showed a conspicuous barcoding gap among Metrichia sequences (highest intraspecific divergence: 4.8%; lowest interspecific divergence: 12.6%). Molecular analyses also allowed the association of larvae and adults of Metrichia bonita sp. nov. from Mato Grosso do Sul, representing the first record of microcaddisfly larvae occurring in calcareous tufa (or travertine). ABGD results agreed with the morphological delimitation of Metrichia species, while GMYC estimated a slightly higher number of species, suggesting the division of two morphological species, each one into two potential species. Because this could be due to unbalanced sampling and the lack of morphological diagnostic characters, we have maintained these two species as undivided.
