description: Machiloides banksi Silvestri, 1911
The very short urosternites and lack of scalges on basal antennal segments place these specimens in the family Meinertellidae, and the presence of styli on the coxae of both the meso- and metathoracic legs places them in the genus Machiloides Silvestri. The only other known Nearctic species of this genus is M. petauristes Wygodzinsky and Schmidt, from which M. banksi is separated by the pigmentation pattern of the clypeus, maxillary palpi, and legs, and the longer maxillary palp segment 4 (Wygodzinsky and Schmidt 1980). Machiloides petauristes is known from New Jersey; 31 other species of the genus live in temperate South America, central and southern Africa, Madagascar, southeastern Australia and Tasmania, and Spain (Wygodzinsky and Schmidt 1980, Mendes 1981b, Notario-Muñoz et al. 2013). Wygodzinsky and Schmidt (1980) also reported members of Machiloides from Tennessee but did not indicate which species, while Notario-Muñoz et al. (2013) portrayed the Nearctic distribution of the genus Machiloides in a rough map as extending in the eastern United States from the Mississippi River to the Florida peninsula, north to Lake Erie and New England.
Machiloides banksi was previously known in the primary, peer-reviewed literature from Virginia, Maryland, North Carolina, and Arkansas (Silvestri 1911; Wygodzinsky and Schmidt 1980; Mendes 1981b). Online records from GBIF (Bartlett and Sellers 2018a, 2018b, 2018c; Bowser 2019b, 2019c; retrieved 21 August 2019) of observations of M. banksi include the following: Alabama: Tuscaloosa County: Tuscaloosa, 14 February 2016, J. Abbott; Arkansas: Prairie County: Wattensaw State Game Area, I-40 pulloff between Fredonia and Hazen, 12 May 2009, J.Cossey; Georgia: Dekalb County: Stone Mountain, 15 July 2011, Matt Edmonds; Missouri: Stone County: Nixa. James River off of Covered Bridge Road just upstream of Bowser Residence, 10 April 2013, Matt Bowser and Ethan Bowser; North Carolina: Durham County: Durham, Burden′s Creek Beech Slope, between highway 55 and Alston, 19 March 2011, “Cotinus”; Virginia: no additional locality data, 7 March 2009, Scott Justis. Despite the online records, the records from Alabama and Mississippi in the MEM represent new state records for this species, genus, and family in the published, peer-reviewed literature.
The BOLD Barcode Index Number for M. banksi, based on specimens from Arkansas, is AAM7560 (Ratnasingham and Hebert 2007). This was the only species represented in the MEM by occasional large numbers per sample, with up to 60 individuals in one vial.
