Pseudopolydesmus serratus, metatergite and paranota of body ring 9. Integrative Research Center, Field Museum of Natural History. For example, in step 1a of his key to species, Withrow identified the Ps. serratus, denticles always distinct. This one was photographed in Sutton Massachusetts walking across my back deck. One type lot found, from the Saline locality: labelled ‘= pinetorum’ by Withrow, contains genitalia vial with two intact male gonopods and three or four fragmented male and female specimens, including one female with vulvae everted. 34, ♂ HT (USNM, vidi). We thank Kal Ivanov and staff at the VMNH for the loan of Pseudopolydesmus specimens and support during visits by D.A.H. – Chamberlin & Hoffman, 1958: 69. High-pass filters were used to adjust white balance: 2.0–3.0 high pass for visible light and 5.0–6.0 high pass for UV.

Several Pseudopolydesmus species can be distinguished easily by the shape and size of the paranota. nov.). canadensis species group (see next paragraph). Small, with body length ranging from 8.8 to 12.7 mm and an average body length of 10.5 mm (N = 31; Withrow, 1988: 124, 199). We found one jar at VMNH labelled ‘PARATYPE’, containing two vials. Type lot 1 (probably the four specimens described by Chamberlin): contains one male with a single gonopod in situ, one intact female, and two small vials; first small vial labelled ‘MALE HT’ by Withrow, contains one male with a single gonopod in situ and two dissected gonopods (one damaged); second vial labelled ‘Lectoallotype’ by Withrow, contains one fragmented female. For example, a medial process between m2 and m4 must be labelled m3 based on position, whereas m4 is recognized by a tuft of special bristles that do not arise from sockets as setae, but project continuously from the cuticle. Like other millipedes in Central America, this species sticks to dark, humid nooks within the forest, favoring rotting trees, piles of leaf litter and soil, caves, and other concealed places. caddo and Ps. In particular, the translucent cuticle of Pseudopolydesmus gonopods makes some processes and flanges difficult to distinguish using white light. Unlike true setae, these bristles are not socketed at the base; instead, they project continuously from the cuticle of the telopodite. The North American Millipede (Narceus americanus) is common east of the Mississippi as well as nine other states – Arkansas, Iowa, Kansas, Louisiana, Minnesota, Missouri, Nebraska, Oklahoma and Texas. Trailing margin concave, strongly curved. The camera was set to ISO 100 with a shutter speed of 1/200 and auto white balance. 51. Clearly smaller than all other congeneric species.

Pseudopolydesmus paludicolus Hoffman, 1950: 222, fig. 4, ♂ HT (USNM, vidi). Polydesmus canadensis Newport, 1844. The diversity of gonopodal structures (copulatory organs in males) and the lack of a standardized terminology based on explicit homology hypotheses among members of Polydesmidae hampers the comparison of taxa in it. Although millipedes are often called "thousandleggers," they actually have far fewer legs, but each body segment has two pairs of very short legs. again king ... With the proliferation of nighttime security cameras, homeowners are seeing Anterior blister row thicker than median blister row along its entire breadth, and MB row thicker than PB row.

We are grateful to Jonathan Coddington and Dana De Roche for the loan of the type specimens of Pseudopolydesmus from the USNM. millipede families are not clearly defined on the basis of apomorphic (or at least on a unique combination of plesiomorphic) characters. If you'd like your blog added to his line-up just visit the link here (click the image) and send him a request. Usually larger than Ps. Tergal blister pattern in Pseudopolydesmus less distinct than the strongly impressed pattern of Polydesmus.

We currently track 186 animals in North-America and are adding more every day! Pseudopolydesmus serratus (Say, 1821) was found by the American entomologist Thomas Say while collecting on the eastern shore of Virginia. Trailing margin moderately concave, less so than Ps. Dixidesmus nitidus – Chamberlin & Hoffman, 1958: 67. The bright coloration is a warning to predators. 3, after Hoffman, 1974).

Here, we synonymize four of the remaining five. These synonymies often addressed species names originally based on minute variations in gonopod morphology. Pseudopolydesmus Attems, 1898: 270, 479. serratus), from which he described both an unusually large seminal chamber and a well-developed pulvillus. With such a wide distribution, a variety of regional names have developed, including American giant millipede, cherry foot millipede, iron worm and worm millipede. B, right gonopod, medial view. (♂ HT and 13 ♂ PT, USNM, vidi): Chamberlin (1943a) described ♂ HT, ♀ allotype, and approximately ten additional ♂/♀ PT from University City, St. Louis Co., MO, USA, collected 29 March 1936 by L. Hubricht. – Chamberlin & Hoffman, 1958: 71. ... segment. Likewise, a very slight transverse furrow may sometimes separate the two setae of the CB, suggesting that the CBs represent a merging of blisters from the anterior and median rows. Non-type lot 2: labelled ‘Paratypes’, collected 8 March 1936, from Creve Coeur Lake Park, St. Louis Co., MO, USA, containing seven specimens belonging to three species: two males of Ps. collinus. 25A); e4 medium-sized, unusually prominent, basal to terminal bristles. I feel honored to be included in the list of best blogs for 2010. Some have flatter bodies, while others are very tubular. Adult body coloration is dark brown to gray with reddish-orange banding. I recently wrote a childrens book about Butterflies and Moths. 3). 17): Corners of paranota forming a broad rectangle, nearer to a square than any other Pseudopolydesmus species. Anterior, median and posterior blister rows subequal in thickness. Holotype, Polydesmus natchitoches, from genitalia vial (USNM).

We found two type lots, both labelled ‘Types’ by Chamberlin and with older labels erroneously identifying the specimens as Ps. Hoffman (1999), in his checklist of North American millipedes, recognized 12 Pseudopolydesmus species and introduced a number of new synonymies, differing partly from those by Withrow. Processes e1, e3 and m4 absent. Strongly flanged medial surface bearing m2 and m3 (Figs 30–31) …………………………Ps. Posterior margin of gonocoxa divided into ventral and dorsal plate-like lobes that partly surround the telopodite basally. Oxford University Press is a department of the University of Oxford. The Pseudopolydesmus gonopod consists of a moveable telopodite with a single distal branch (acropodite) subtended by a large coxa and cannula typical of Polydesmida. Click the picture above, to visit their website and locate their contact info. A black card was used for the background to contrast with the colour of the specimens. Absent from Georgia and peninsular Florida. Also note the characteristic silhouette of the gonopods of Ps. Medium, with body length ranging from 13.6 to 25.6 mm and an average body length of 18.6 mm (N = 212; Withrow, 1988: 76, 199). Lateral blisters aligned with longitudinal axis. Connecting these four points allows overall paranota dimensions to be described as a square, rectangular, trapezoidal, parallelogram shaped or rhomboid. The putative associations of leg podomeres with parts of the male gonopod have shifted over time owing to the difficulty in assigning homology to the podomeres distal from the coxa, resulting in several terms that have multiple precise definitions. For both UV and visible light photographs, the preferred rendering method was Method C (pyramid) at full resolution [for the images of Ps. C. spinigerus and N. americanus [CREDIT: Univ.

Polydesmus echinogon Chamberlin, 1942b: 10, fig. Minnesota east to southern Quebec, south to northern South Carolina, west to east Texas. They're not insects—they’re actually more closely related to lobsters, shrimp, and crayfish. Trigoniulus corallinus is also sometimes called the rusty, red, or rusty-red millipede. There are two type lots. I believe they're Narceus annularis - one of the largest North American millipede species and I'm guessing they're out and about this fine spring day because they're looking for love. and P.E.M. Notes are provided on the disposition of type material for each nominal species. Spotted by SeanCorcoran. Pseudopolydesmus paroicus – Chamberlin, 1943c: 18. 9): Corners of paranota forming a trapezoid, with the anterior (AMC to ALC) edge longer than the posterior (PMC to PLC) edge. Process m3 absent.

Type lot: contains two ♂ PT, ♂ HT with gonopods removed, distal extremities of one broken gonopod (without pulvillus). Moreover, gonopod terminology varies in the family Polydesmidae between genera and among different authors (as discussed by Hoffman, 1974). Xystodesmid Millipede. Anterior blister row medially much thicker than median blister row, narrowing laterally to become much narrower than median blister row. (Figs 8, 33): Gonocoxa ventral lobe with two gonocoxal plates stacked dorsoventrally (Fig. Highlighted words throughout the book encourage children to learn scientific terminology by using our vocabulary section. Full color photographs, and fun facts help children learn about these amazing creatures. Learn More » North American millipede. Since its first description, the genus has accrued ~480 specific names, of which > 250 remain placed in that genus. Vial contains one male and one dissected gonopod, tip of gonopod damaged. The specimen is crystal clear, indestructible and transparent. UV-induced fluorescent imaging of Pseudopolydesmus paludicolus (gonopod images) and Pseudopolydesmus collinus (gonopod and tergite images) was carried out according to methods already described by Marek (2017). 5B).

We emphasize caution when using these terms, because they imply false homologies with podomeres of the walking legs (Petit, 1976). in scanning electron microscope work. Summary of telopodite processes in Pseudopolydesmus, Telopodite processes of Pseudopolydesmus species in key order. canadensis and that the intermediate medial process in Ps. minor and Ps. This is not the world's largest millipede, though. Verhoeff noted the close similarity of the tergal sculpture pattern (‘Rückenskulptur’, Verhoeff, 1931: 308) between Polydesmus and Pseudopolydesmus. At USNM, we found an additional type lot from Greenbrier Cove, Sevier Co., TN, USA: labelled ‘Paratype’, contains at least one female, several males, one dissected gonopod in genitalia vial and one small vial labelled ‘Lectoallotype’; the small vial contains one female with one dislodged vulva. Many early authors (as late as Attems, 1940) published descriptions and gonopod illustrations of Ps. paludicolus. Anterior blister row thicker medially than MB row, MB row thicker than PB row. Owing to its unique position, offset ectad from the edge of the telopodite, we hypothesize that m3 is present only in Ps. North American Millipede The North American Millipede, or as it is sometimes called American Giant Millipede, and Iron Worm (Narceus americanus) is found throughout the Eastern United States and can reach lengths up to 3 inches or more.

Dana De Roche generously supported work on the specimens during the visit from P.S. Induced fluorescence of the cuticle or integument has also been documented in numerous orders of centipedes, arachnids, insects and crustaceans (Lawrence, 1954; Rubin et al., 2017; Welch et al., 2012). UV illumination was from three Convoy S2+ Nichia 365 nm LED flashlights (Shenzhen Convoy Electronics Co., Ltd., China) that contain a Nichia NCSU276A U365 UV LED emitter (Nichia Corporation, Tokushima, Japan), with a peak emission spectrum of 365 nm.
