Holotype (USNM, ultraviolet enhancement). Described variously in the genera Polydesmus, Pseudopolydesmus and Dixidesmus Chamberlin, 1943, many of these species names have proved redundant. According to Hoffman (1980): ‘The Palearctic fauna of this family is in complete chaos [and] nothing short of an overall revision will bring any kind of order’. This is unlike male Polydesmus, in which tubercles of leg pairs 9 and 10 (the first two leg pairs directly posterior of the gonopods) are absent or very slight. Narceus americanus is a large millipede of eastern North America. Leading and distal margins moderately curved, similar to Ps. In the order Polydesmida, the anterior leg pair of the seventh body ring (eighth leg pair) in males is modified into a pair of sperm transfer organs called gonopods. 056958. paroicus; Po.

All non-ozoporous body rings bear three denticles along each paranotum, whereas ozoporous segments bear four denticles. Dark brown to gray and reaching about 4 inches long, they often have orange to red legs lending them the name cherry foot millipedes. Pseudopolydesmus serratus (Say, 1821) was found by the American entomologist Thomas Say while collecting on the eastern shore of Virginia.

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. 16A). Loomis & Hoffman (1948), Causey (1952) and Shelley (1988) all published species-level synonymies correcting many of the redundancies in their comparisons of various species of Pseudopolydesmus.

Most spiders are harmless to humans and provide a great service to us by eating untold amounts of insects. Beginning with Thomas Say’s (1821) description of Pseudopolydesmus serratus, 32 species names have been associated with the genus Pseudopolydesmus. Koch (1847) described the type locality only as ‘Nordamerika’. The North American millipede can grow up to 3.9 inches. inconstans, because, unlike in most Pseudopolydesmus, the collum is narrower than the mandibles and tergal setae are clearly visible under the dissecting microscope. – Chamberlin & Hoffman, 1958: 69.

A, right gonopod, ectal view. 4) very similar to other members of Polydesmidae, such as Po. the summer and fall of 2019, the eastern US has seen a bump in cases of a Pulvillus medium-sized, midway between base and terminus of acropodite. 4. canadensis is instead often referred to as Po. Dixidesmus penicillus Chamberlin, 1943c: 19, fig. Williams & Hefner (1928) reported Polydesmus moniliaris C. L. Koch, 1847 as common and abundant throughout the state of Ohio. For the review of the genus we provide here, we examined all available type material and imaged specimens using various macrophotographic techniques, including the use of UV fluorescence of the cuticle to provide false-colour images with enhanced detail. In Pseudopolydesmus, the leading margin (AMC to ALC) and distal margin (ALC to PLC) are usually convex and the trailing margin (PLC to PMC) is concave. In the spring, they emerge and mate. They will brood the egg by wrapping themselves around it. (Figs 23–25): Gonocoxa ventral lobe with two gonocoxal plates stacked dorsoventrally (Fig. Usually larger than Ps. The functional morphology of the ‘large seminal chamber’ and its relationship, if any, with the sperm groove is uncertain and deserves further anatomical study (see Verhoeff, 1928, 1931; Carl, 1941).

Although some initial efforts have been made (Withrow, 1988; Djursvoll et al., 2000), a comprehensive phylogenetic analysis addressing genus-level relationships in Polydesmidae remains missing. 13a. Their coloration varies from pink to brick red to brown, and their shallowly raised dorsal blisters give them the flat-backed appearance typical of other millipedes in the order Polydesmida (Figs 1, 2). The four edges of this quadrilateral are referred to in this paper as the anterior edge (between AMC and ALC), posterior edge (PMC to PLC), medial edge (AMC to PMC) and lateral edge (ALC to PLC). – [Withrow, 1988: 115, figs 50, 77, 96, 100, 104, 116, 118, 122–126, map 9, tables 9–11.] If you are new to ants, you might enjoy this delightful presentation by ant 2).
