- A re-evaluation of the milliped genus Motyxia Chamberlin, with a re-diagnosis of the tribe Xystocheirini and remarks on the bioluminescence (Polydesmida: Xystodesmidae) (1997)
- Motyxia Chamberlin is comprised of eight species of bioluminescent xystocheirine millipeds in which the gonopodal solenomere arises at different positions, from basally and subbasally on the acropodite to being fused with the companion acropodal branch and detaching proximad or near midlength. Previous synonymies ofAmplocheir Chamberlin and LuminodeslnllS Loomis and Davenport under Motyxia are confirmed as is its assignment to the tribe Xystocheirini, which is redefined. Component species are 111. Iwnw Chamberlin, the type species, monica Chamberlin, sequoiae (Loomis and Davenport), tularea (Chamberlin), sequoia (Chamberlin), pior Chamberlin, porrecta Causey and Tiemann, and tiemanni Causey. Motyxia sequoia is comprised oftwo races, the nominate and sequoia alia Causey and Tiemann; sequoia ollae Causey and Tiemann is properly a subspecies of tularea.1I1otyxiapiorform secea is an invalid name without standing in nomenclature, and M. tejona Chamberlin, andM. expansa and exilis, both by Loomis, are placed in synonymy under M. monica, the oldest name for the southernmost species, as Polydesllws dissectus Wood is referrable to Xystocheir Cook. The bioluminescence is a continuous, neon-white glow of the entire dorsal surface including the antennae and legs.Its visibility at night suggests a warning function analogous to aposematic coloration. The phenomenon may observe a circadian rhythm, and controlled photoperiod experimentation may be productive.
- Distribution of the American milliped genus Boraria Chamberlin, 1943: Introductions of B. stricta (Brölemann, 1896) in New York and B. infesta (Chamberlin, 1918) in Connecticut; indigenous occurrence of B. profuga (Causey, 1955) in Louisiana (Diplopoda: Polydesmida: Xystodesmidae). (2011)
- The southern Appalachian millipeds Boraria stricta (Brölemann, 1896) and B. infesta (Chamberlin, 1918) (Diplopoda: Polydesmida: Xystodesmidae) have become established in Westchester Co., New York, and Hartford Co., Connecticut, respectively. Only three individuals are available for the latter, but B. stricta has established a reproducing population in southern New York state. This species is also recorded from Bland Co., Virginia, in the Ridge and Valley Physiographic Province. Boraria profuga (Causey, 1955) comprises two allopatric populations, one in Montgomery Co., Arkansas, and the other in Ouachita Parish, Louisiana. Distributional records and gonopod drawings are presented for these species plus B. deturkiana (Causey, 1942).
- The Milliped order Glomeridesmida (Diplopoda: Pentazonia: Limacomorpha) in Oceania, the East Indies, and southeastern Asia; first records from Palau, the Philippines, Vanuatu, New Britain, the Island of New Guinea, Cambodia, Thailand, and Borneo and Sulawesi, Indonesia (2011)
- The taxonomically neglected milliped order Glomeridesmida and family Glomeridesmidae (infraclass Pentazonia, superorder Limacomorpha) inhabit 21, rather than seven, regions of the world, being newly recorded from Thailand; Cambodia; the Republics of Palau, the Philippines, and Vanuatu; New Britain, Bismarck Archipelago; the Island of New Guinea (both West Papua [formerly Irian Jaya], Indonesia, and Papua New Guinea); and Sulawesi and Borneo, Indonesia. Occurrence in Fiji is confirmed with two additional samples, and discovery is predicted in southern China, Myanmar, and perhaps Madagascar. Coupled with published localities, these records suggest subcontinuous (super)ordinal and familial ranges extending some 12,480 km (7,800 mi) southeastward from northwestern Thailand to Fiji. Though infrequently encountered, the taxa may actually be diverse and abundant within this area, which encompasses all of the Indochina and Malay peninsulas, the Philippines, Palau, the Island of Borneo and Indonesia, Papua New Guinea, the Solomon and Santa Cruz Islands, Vanuatu, and Fiji; it excludes Taiwan, Australia, New Caledonia, and the Loyalty Islands. The paucity of preserved individuals probably results from their dark pigmentations and minute sizes, adults being <6.5 mm long; Berlese extractions and sieved litter techniques are recommended over hand collecting. Glomeridesmida are much more continuous, widespread, and abundant in the “east” than previously believed and clearly do not comprise a minor, insignificant taxon. The first glomeridesmidan photos are published.
- The first vouchered milliped records for Prince Edward Island and additional new records from the Maritime Provinces of Canada (Arthropoda: Diplopoda) (2011)
- Four milliped species, substantiated by preserved voucher samples, are reported from Prince Edward Island, Canada. All are introduced European species that now occur widely in both Canada and the United States, and the panglobal Asian paradoxosomatid, Oxidus gracilis (C. L. Koch, 1847), is listed as probable. Choneiulus palmatus (Némec, 1895) (Julida: Blaniulidae) is newly recorded from New Brunswick, and four representatives of the Julidae are cited from Nova Scotia. Discovery of Cylindroiulus punctatus (Leach, 1815) (Julidae) in this province constitutes the second record from both Canada and North America, the other being in Newfoundland.
- Annotated checklist of the millipeds of Florida (Arthropoda: Diplopoda) (2000)
- The milliped fauna of Florida consists of 8 orders, 18 families, 34 genera, and 51 species and subspecies; it comprises six elements: widespread species occurring widely in Florida, northern species reaching their southern limits in north Florida, neotropical species occurring naturally in Florida or adventive there, oriental adventives, Florida endemics, and southeastern endemics. A complete listing of these taxa is provided, with published and new records from the state, synonyms, and type localities. Georgiulus paynei Hoffman, Cleidogona alata Causey, and Pseudopolydesmus serratus (Say) are newly recorded from the state, and Eurymerodesmus serratus Shelley is deleted; Pseudojulus obtectus (Bollman) is recorded from Alabama.

- Narceus woodruffi Causey, a forgotten milliped species (Spirobolida: Spirobolidae) (2002)
- Previous treatments ofthe east-Nearctic spirobolid genus Narceus Rafinesque have overlooked the name, N. woodruffi Causey. The holotype is lost, but examinations of a non-typical male and two paratype and three non-typical females show it to be a valid species, perhaps endemic to north Florida, distinguished by its small size and the configurations of the gonopods and coxal lobes of legs 3-6 in males. Supplemental anatomical notes are presented on the non-typical male along with comparative drawings of the lobes and gonopods of N. woodruffi, N. american us (Beauvois), and N. annularis (Rafinesque); distributions of species of Narceus in Florida are depicted on a map. Substantial size differences between ostensibly conspecific males of N. american us in Texas and Arkansas suggest that Narceus may be more complex than the current concept of four species.
- Parajulid milliped studies V. The genera Pseudojulus Bollman and Arvechambus Causey (Parajulinae: Aniulini) (2002)
- The parajulid milliped genus Pseudojulus Bollman comprises four species: P. obtectus (Bollman), P.paynei (Hoffman), n. comb., andP. carolinensis andP. coastalis, new species; Arvechambus Causey comprises two species, A. hummi and A. weemsi, both by Causey. Georgiulus Hoffman is placed in synonymy under Fseudojulus; G. hubrichti Hoffman is placed under P. pay/wi; andA. australis Causey is placed under A. hummi. The genera are sympatric in north Florida and southern Georgia, but Pseudojulus extends northward to coastal South Carolina and southcentral North Carolina, and westward to Alabama west of Mobile Bay. Both genera belong to the Aniulini and possess unique features; in Pseudojulus the anterior gonopod coxae are fused into a "shelf' on the dorsal surface ofthe complex that extends ventrad along the caudal margin and possesses a pair of posterior median syncoxallobes or laminas of varying lengths and configurations. Arvechambus exhibits a suite of apomorphies and is sister to the rest of the tribe collectively: the 8th sternum possesses elevated lateral lobes that overhang the sides ofthe gonopodal aperture; the 7th pleurotergite possesses lobes that also overlie the sides of the aperture; the anterior gonopods lack lateral syncoxal processes, the coxal lobes, much larger than in other tribal genera, arise laterad and obscure part of the telopodite in anterior view, and the telopodite is elongate rather than clavate; and the 2nd pleurotergite in females possesses lobes that overhang and effectively close the cyphopodal aperture.
- The milliped genus Euryurus Koch, 1847 (Polydesmida: Euryuridae) west of the Mississippi River; occurrence of E. leachii (Gray, 1832) on Crowley’s Ridge, Arkansas (2012)
- The milliped genus Euryurus Koch, 1847, and the species, E. leachii (Gray, 1832) (Polydesmida: Euryuridae), are recorded from three sites on the northern part of Crowley’s Ridge (Cross, Lee, and Poinsett counties), Arkansas, where the only prior familial records are of Auturus evides (Bollman, 1887). Coupled with the published locality of E. leachii in Phillips Co., at the southern extremity of the Ridge, the only known occurrences of both the genus and species in Arkansas and west of the Mississippi River are in this physiographic feature. The Arkansas population is geographically peripheral but anatomically intermediate between the two recognized subspecies, E. l. leachii and E. l. fraternus Hoffman, 1978, and we do not assign it to a race. Molecular investigations seem necessary to resolve relationships in the “E. leachii complex.”
- Centipedes and Millipeds (Arthropoda: Diplopoda, Chilopoda) from Saba Island, Lesser Antilles, and a Consolidation of Major References on the Myriapod Fauna of “Lesser” Caribbean Islands (2012)
- The chilopod, Cryptops hortensis (Donovan, 1810) (Scolopendromorpha: Cryptopidae), and the diplopods, Pseudospirobolellus avernus (Butler, 1876) (Spirobolida: Pseudospirobolellidae) and Oxidus gracilis (C. L. Koch, 1847) (Polydesmida: Paradoxosomatidae), are newly recorded from Saba Island, Lesser Antilles, which also harbors one additional scolopendromorph and four more chilognath millipeds. Except for the plausibly native scolopendrid centipede, Scolopendra alternans Leach, 1813, all are human introductions. Concentrated sampling is needed in the cloud/elfin forest atop Mt. Scenery, where indigenous millipeds may reside, and with extraction techniques throughout the island, to potentially document the diplopod subclass Penicillata. Nine small Caribbean islands in addition to Saba have been incorrectly reported as lacking diplopod records because publications citing them were overlooked by past authors. Works documenting myriapods from small Caribbean islands are consolidated.
