Abstract A description is provided for Drechmeria coniospora. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. DISEASE: Endoparasitic in free-living nematodes. HOSTS: Rhabditis (DÜRSCHNER, 1983), Meloidogyne, Panagrellus (JANSSON et al., 1985b; TOWNSHEND et al., 1989; ZHANG, 1994), Aphelenchoides; on other nematodes conidia may adhere but do not penetrate (JANSSON et al., 1987; DIJKSTERHUIS et al., 1993). It also attacks adults and pre-infective stages of the entomopathogenic Neoaplectana spp. (POINAR & JANSSON, 1986) and Haemonchus contortus in ovine faecal pellets (SANTOS & CHARLES, 1995). GEOGRAPHIC DISTRIBUTION: NORTH AMERICA: Canada, USA. SOUTH AMERICA: Brazil. ANTARCTICA: Antarctic Is. ASIA: China, Japan. EUROPE. TRANSMISSION: By nematodes and soil water.

We clarify the diagnosis and geographic distribution of the widespread, variable eastern coastal species Languria taedataLeConte, 1854, in North America. After examining types and the range of variation and geographical distribution of thespecies, we propose synonymy of L. erythrocephalus Blatchley, 1924, with L. taedata, new synonymy. We report the dis-covery of an all-piceous form (“Form C”), the first of the genus, found primarily along the western Gulf Coast of the Unit-ed States. The recognition of this form requires a modification to the most recent key to North American genera ofLanguriinae. The larvae of L. taedata feed within the stems of Spartina alterniflora Loisel (Poaceae). We provide addi-tional notes on the occurrence of L. taedata in coastal marshes in Louisiana. The types of L. apicalis Motschulsky, L. ni-griceps Motschulsky, L. obscura Motschulsky, and L. rufiventris are reexamined. A revised synonymic checklist is provided for North American Languriini.

I wish to draw particular attention to this genus and its allies. I have, in 1865, drawn a parallel between the group and the Hawk Moths, from the young stages and the peculiar pupation, and in my pamphlet on “the Hawk Moths of North America,” I hae discussed the probabilities of their relationship. But I here wish to point out that the group is American; that in America we may except to find old types among that portion of the fauna which is indigenous, pre-tertiary, and to this Citrheronia belongs.

Within Astraea Klotzsch (1841: 194), Astraea lobata (Linnaeus 1753: 1005) Klotzsch (1841: 194) may be considered the most taxonomically complex species due to its wide geographical distribution and the several varieties that have been proposed for this species by Müller Argoviensis (1866, 1874). In his concept, Müller Argoviensis (1866) united under Croton lobatus Linnaeus (1753: 1005) plants with 3–5-partite leaves almost as long as the petioles, subulate stipules, the bracts not well developed and ovaries with varied indumentum. In De Candolles’s Prodromus, Müller Argoviensis (1866) recognized eight varieties, maintaining this concept in the Flora Brasiliensis (Müller Argoviensis 1874) with few modifications. Morphological characters and geographical distribution support the recognition of some of these varieties as species distinct from A. lobata. As part of an undergoing taxonomic revision of Astraea, these distinct taxa must be validly published for further studies on this genus. Therefore, in this note we propose these novelties with commentaries about morphology and geographic distribution, along with photos to illustrate them and lectotypifications when necessary.

Objective We report the impact of the coronavirus disease 2019 (COVID-19) pandemic on cardiac surgery trainee education in North America. Methods A survey was sent to participating academic adult cardiac surgery centers in North America. Data regarding the effect of COVID-19 on cardiac surgery training were analyzed. Results Responses were received from 53 academic institutions with diverse geographic distribution. Cardiac surgery trainee re-deployment to alternative clinical duties peaked at the height of the pandemic. We stratified institutions based on high ( n = 20) and low burden ( n = 33) of patients hospitalized with COVID-19. The majority of institutions have converted didactics (high burden 90% vs low burden 73%) and interviews for jobs/fellowships (high burden 75% vs low burden 73%) from in-person to virtual. Institutions were mixed in preference for administration of the licensing examination, with the most common preference for examinations to be held remotely on normal timeline (high burden 45% vs low burden 30%) or in person with more than 3-month delay (high burden 20% vs low burden 33%). Despite the challenges experienced during the COVID-19 pandemic on trainee clinical experience, re-deployment, and decreased operative volume, institutions expected their trainees to graduate on schedule (high burden 95% vs low burden 91%). Conclusions Our study demonstrates that actions taken during the COVID-19 pandemic has led to disruptions in cardiac surgery training with transition of didactics and interviews virtually and re-deployment to alternative duties. Despite this, institutions remain optimistic that their trainees will graduate on schedule.
