The Trichoptera of Panama XXIV. Fifteen new species and two new country records of the caddisfly genus Neotrichia (Trichoptera, Hydroptilidae), with a key to all known Panamanian species.

In this paper, 15 new species of microcaddisflies in the genus Neotrichia Morton, 1905 (Trichoptera, Hydroptilidae) from Panama are described and illustrated: Neotrichiaabrebotellasp. nov.; Neotrichiacandelasp. nov.; Neotrichiacodazasp. nov.; Neotrichiaemberasp. nov.; Neotrichiaflennikenisp. nov.; Neotrichiahondasp. nov.; Neotrichialandisaesp. nov.; Neotrichialenatisp. nov.; Neotrichiamindyaesp. nov.; Neotrichiapanamensissp. nov.; Neotrichiaparajarochitasp. nov.; Neotrichiaparaxicanasp. nov.; Neotrichiasnixaesp. nov.; Neotrichiaspanglerisp. nov.; Neotrichiaveraguasensissp. nov. In addition, two new country records are presented: Neotrichiaminutisimella (Chambers, 1873) and Neotrichiavibrans Ross, 1944. Finally, the male of N.vibrans is re-illustrated, the female is illustrated and descriptive information given, and a key is provided to the males of all current Neotrichia species in Panama. There are now 45 species of Neotrichia and a total of 525 Trichoptera species recorded from Panama.

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

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.

The Trichoptera of Panama. XIX. Additions to and a review of the genus Leucotrichia (Trichoptera, Hydroptilidae) in Panama.

Prior to 2016, three species of caddisflies in the genus Leucotrichia (Trichoptera: Hydroptilidae) were known from Panama. Subsequently, one new species and four new country records were added to Panama's fauna. Herein, four new species are described (Leucotrichiacortadera sp. nov., L.holzenthali sp. nov., L.luma sp. nov., L.ruiteri sp. nov.) and two new country records added for Panama (L.botosaneanui Flint, 1996, L.hispida Thomson & Holzenthal, 2015). The resulting total of 14 species makes Panama the most species-rich country for this genus. Panama's species assemblage is most similar to Costa Rica and Mexico. However, the similarities among faunas in all these countries is very low (< 35%). Thus, more new country records are possible with additional collecting. Recent collections (2015-2021) of new caddisfly species and country records in this genus were effected primarily by use of Malaise traps. Our collections also evidenced multiple species from the same collecting site, with seven species each found in both lowland and mid-altitude sites. Investigation of the distribution of Leucotrichia species with altitude reveals a preference by several species for higher altitude locations. Additional Malaise trap collections over extended time periods are needed to verify the validity of all observations and preliminary conclusions made to date.

Larva of Nothotrichia shasta Harris & Armitage (Trichoptera: Hydroptilidae) from California, USA, with its phylogenetic and taxonomic implications.

Nothotrichia Flint 1967 is a small genus of infrequently collected microcaddisflies known from Chile and Brazil in South America, Costa Rica in Central America, and the United States in North America. Previously known only from adult specimens, we provide the first description and illustration of a larva in the genus, the larva of N. shasta from California, USA. We provide characters to separate Nothotrichia from other similar genera and an updated key to larval Hydroptilidae modified from that of Wiggins (1996). Larval characters provide additional evidence for the phylogeny and classification of the genus, which we now place tentatively in tribe Ochrotrichiini (subfamily Hydroptilinae).

First report of bluetongue virus serotype 1 isolated from a white-tailed deer in the United States.

In November 2004, tissues were collected from a hunter-killed white-tailed deer in St. Mary Parish, Louisiana. Bluetongue virus (BTV) was isolated from the tissues; however, the isolate could not be identified as any of the US domestic serotypes. Subsequent testing by virus neutralization using serotype-specific antiserum tentatively identified the isolate as BTV serotype 1 (BTV-1), which had not previously been found in the United States. Primers were designed based on the sequence of an outer capsid protein gene of a South African BTV-1 strain. Reverse transcription-polymerase chain reaction testing with the BTV-1 primers and product sequencing confirmed the Louisiana isolate as BTV-1. This is the first report of BTV-1 in the United States.
