They are closely related to the sexually reproducing slough crayfish, Procambarus fallax, which is native to the southeastern United States. Previous studies have shown that marbled crayfish are morphologically very similar to P. fallax. However, different fitness traits, reproductive incompatibility and substantial genetic differences suggest that the marbled crayfish should be considered an independent species. This article provides its formal description and scientific name, Procambarus virgin- alis sp. nov. Key words: parthenogenesis, annulus ventralis, genetic analysis, mitochondrial DNA Introduction Marbled crayfish were first described in 2001 as the only known obligatory parthenogen among the approximately 15,000 decapod crustaceans (Scholtz et al., 2003). The animals were first described in the German aquarium trade in the late 1990s (Scholtz et al., 2003) and became widely distributed in subsequent years under their German name "Marmorkrebs". Stable populations have developed from anthropogenic releases in various countries including Madagascar, Germany, Czech Republic, Hungary, Croatia and Ukraine (Chucholl et al., 2012; Jones et al., 2009; Kawai et al., 2009; Liptak et al., 2016; Lokkos et al., 2016; Novitsky & Son, 2016; Patoka et al., 2016).

Marbled Crayfish (Marmokrebs) Control in Ohio
OHIO DIVISION OF WILDLIFE Marbled Crayfish (Marmokrebs) Control in Ohio Injurious Aquatic Invasive Species (IAIS) are animals that cause or are likely to cause damage or harm to native ecosystems or to commercial, agricultural, or recreational activities that are dependent on these ecosystems. The Ohio Department of Natural Resources, Division of Wildlife has the authority to establish an active list of Ohio IAIS high-risk species through a risk-analysis process to evaluate non-native candidate species via Ohio Administrative Code 1501:31-19-01. Listed species are unlawful to possess, import, or sell unless dead and/or preserved. Prevention: Risk Reduction State and federal partners are working to eliminate the risk of invasive Marbled Crayfish (also known as Marmokrebs) by preventing this Ohio-listed IAIS from public possession and sales in Ohio and to prevent their introduction and spread in Ohio waters and fish culture facilities. Background Marbled Crayfish (Marmokrebs) • Adult size – 10 to 13 cm (4 to 6 inches). Procambarus fallax f. virginalis • Grow and mature rapidly in captivity. • Not native to Ohio, Great Lakes or Ohio River watersheds. • Not known to occur in the wild, except through accidental or purposeful release. • Mostly a cultured species in the North American and European pet trade. “Marmokrebs” is its European common name. An all-female species, it reproduces asexually through parthenogenesis. • Closely related to the slough crayfish, Procambarus fallax, native to Florida and southern Georgia. Current Status, Management, Control and Exclusion in Ohio • Marbled crayfish have been defined as a high-risk IAIS in Ohio as they are non-native, adult females have a high reproductive capacity, and they can displace native crayfish.

SQUIRREL CHIMNEY CAVE SHRIMP Palaemonetes Cummingi
SQUIRREL CHIMNEY CAVE SHRIMP Palaemonetes cummingi (Photo unavailable) FAMILY: Palaemonidae STATUS: Threatened (Federal Register, June 21, 1990) DESCRIPTION: The Squirrel Chimney Cave shrimp, also known as the Florida cave shrimp, is approximately 1.2 inches (3O millimeters) long. Its body and eyes are unpigmented; the eyes are smaller than those of related surface-dwelling species of Palaemonetes. RANGE AND POPULATION LEVEL: This cave shrimp is known only from a single sinkhole (Squirrel Chimney) in Alachua County, Florida. No more than a dozen individuals have been seen near the surface of the sinkhole water table, but more individuals may exist at greater depths. HABITAT: Squirrel Chimney is a small, deep sinkhole that leads to a flooded cave system of unknown size. The sinkhole is known to support one of the richest cave invertebrate faunas in the nation. Other cave invertebrates found in this sinkhole include McLane's cave crayfish (Troglocambarus maclanei); the light-fleeing cave crayfish (Troglocambarus lucifugus); the pallid cave crayfish (Procambarus pallidus); and Hobb's cave amphipod (Crangonyx hobbsi). These species are found in the shallower portions of a pool in the fissure leading off the sinkhole. They usually cling bottom-side-up to limestone just beneath the water table. These species are adapted for survival in a nutrient-poor, detritus-based ecosystem. REASONS FOR CURRENT STATUS: The Squirrel Chimney Cave shrimp is endemic to a single sinkhole. Any changes in the sinkhole or cave system could eliminate the species. The site is privately owned and the owners are currently protecting the site from trespassers. Urban development associated with the growth of Gainesville, Florida are expected to continue and will most likely alter land use practices in the vicinity of Squirrel Chimney Cave.

This of the Class Malacostraca (such as crayﬁsh) share a set of molecular analysis allows us to verify the homology of homologous neurons. However, expression of molecular previously identiﬁed malacostracan neurons and to identify markers in these neurons has not been investigated, and the additional homologous neurons in malacostracans, homology of insect and malacostracan neuroblasts, the collembolans and branchiopods. Engrailed expression in neural stem cells that produce these neurons, has been the neural stem cells of a number of crustaceans was also questioned. Furthermore, it is not known whether found to be conserved. We conclude that despite their crustaceans of the Class Branchiopoda (such as brine distant phylogenetic relationships and divergent shrimp) or arthropods of the Order Collembola mechanisms of neurogenesis, insects, malacostracans, (springtails) possess neurons that are homologous to those branchiopods and collembolans share many common CNS of other arthropods. Assaying expression of molecular components. markers in the developing nervous systems of various arthropods could resolve some of these issues.

From the Waccamaw River Basin, North and South Carolina
6 April 1998 PROCEEDINGS OF THE BIOLOGICAL SOCIETY OF WASHINGTON 111(1):81-91. 1998. A new species of crayfish of the genus Procambarus, subgenus Ortmannicus (Decapoda: Cambaridae), from the Waccamaw River basin, North and South Carolina John E. Cooper North Carolina State Museum of Natural Sciences, P. O. Box 29555, Raleigh, North Carolina 27626, U.S.A. Abstract.—Procambarus (Ortmannicus) braswelli is a new species of cray- fish from the Waccamaw River basin in North and South Carolina. A primitive member of the Pictus Group, P. braswelli has its closest affinities with P. (0.) chacei, P. (O.) enoplosternum, and P. (O.) pictus. The new species is less closely related to P. (O.) epicyrtus, and distantly related to its geographically nearest relative, P. (O.) lepidodactylus, with which it has been confounded. The occurrence of P. lepidodactylus in North Carolina is currently uncon- firmed. Procambarus braswelli may be distinguished from the other members of the Pictus Group by its combination on the form I male gonopod (first pleopod) of a prominent, truncated, distally directed caudal knob; a large, somewhat bulbous adventitious process; and a long, caudodistally directed me- sial process; and by a long acumen.

White River Crayfish Procambarusprocambarus Acutus Aacutushemimysis Acutus Acutus Anomala
White River Crayfish www.seagrant.psu.edu ProcambarusProcambarus acutus aacutusHemimysis acutus acutus anomala The white river crayfish, also called the white river crawfish and the eastern white river crayfish, is often confused with its southern counterpart, the southern white river crayfish (Procambarus zonangulus). The eastern white river crayfish occurs naturally in the United States and is cultured eastwards from Lousiana to the Atlantic coast northward to Maine, Photo courtesy of Tony Palacios, but has established select non-native populations in locations throughout the East Coast iNaturalist.org, EOL. and in California. Species Description Adult white river crayfish are usually a dark burgundy red but can range in color from pinkish tan to brownish olive with a black “V-shaped” stripe on the abdomen. The carapace is rough and granular and is separated in the middle by a narrow space called the areola. Juveniles are gray with dark spots scattered over the carapace. The claws are long and narrow, delicate in appearance, and have small dark tubercles. This species reaches about 6-13 cm (2.5-5 in) in length. The white river crayfish is nearly impossible to distinguish from the southern white river crayfish without looking at the reproductive structures of a breeding male. It is also confused with the red swamp crayfish (P. clarkii), which have an areola that is straight, or often invisible, and a black “V-shaped” stripe on the abdomen. The juveniles are also typically plain or striped on the carapace instead of spotted. White river crayfish can also be found in streams and ditches with a stronger flow than what is preferred by the red swamp crayfish.

WISCONSIN CRAYFISH IDENTIFICATION GUIDE April 2019 Version
WISCONSIN CRAYFISH IDENTIFICATION GUIDE April 2019 version Craig Roesler Wisconsin DNR – Spooner There are eight species of crayfish that have been found in Wisconsin in recent years. They are: Devil crayfish (Cambarus diogenes) (p.4) Calico crayfish (Orconectes immunis) (p.6) Northern Clearwater crayfish (Orconectes propinquus) (p.8) Rusty crayfish (Orconectes rusticus) (p.10) (non-native) Virile crayfish (Orconectes virilis) (p.12) White River crayfish (Procambarus acutus) (p.14) Red Swamp crayfish (Procambarus clarkii) (p.16) (non-native) Prairie crayfish (Procambarus gracilis) (p.17) The Red Swamp crayfish has only been found in three stormwater ponds in southeastern Wisconsin in recent years where efforts have been made to eradicate it. The Prairie crayfish has only been found in far southeastern Wisconsin (Milwaukee, Waukesha, Racine, Kenosha, and Walworth Counties). This leaves only six species likely to be present in the remainder of the state. The three most commonly found species are the Virile crayfish, the Northern Clearwater crayfish, and the Rusty crayfish. These three species typically comprise more than 90% of specimens in crayfish collections. There are historical reports of Digger crayfish (Fallicambarus fodiens) being found in Wisconsin. This crayfish may have recently been found in the Milwaukee area, but the recent reports have not yet been substantiated. This guide is an attempt to allow simplified identification of Wisconsin crayfish. Technical terms have been avoided*. “Lobster dinner” terms have been used (tail, claws, shell). Color photos depicting useful identification characteristics are provided. A simplified key is included on page 3. A crayfish species can be fairly variable in appearance. All identification characteristics will not be apparent in every specimen.

Cambarus (Depressicambarus) Striatus Hay 1902 Ambiguous Crayfish
Cambarus (Depressicambarus) striatus Hay 1902 Ambiguous crayfish Photo by C. Lukhaup. Distribution, Habitat, and Behavior Cambarus striatus is a widely distributed species, ranging from South Carolina to Florida, west to Mississippi and north through Tennessee into part of Kentucky (Bouchard 1978, Hobbs 1989). It occurs throughout most of Mississippi, except in the Mississippi Alluvial Plain ecoregion (USEPA 2007). Cambarus striatus may be primary, secondary, or tertiary burrowers, depending on the population (Bouchard 1978). Burrowing versus stream-dwelling habits by C. striatus appears to depend, at least in part, on the species with which it is syntopic (Bouchard 1978, Hobbs 1981). Hobbs (1989) noted that the species tends to burrow more in the southern portion of its range, and in Kentucky, Taylor and Schuster (2004) collected the species from “creeks and rivers of all sizes” but not from burrows. In Mississippi, small juveniles are common in streams from fall through spring, especially streams that dry seasonally, and it is not uncommon to find a few mature individuals in streams, particularly during spring and fall. Life Colors and Distinctive Characters Cambarus striatus of two color morphs typically coexist in Mississippi streams (personal observations). One morph has a uniform or very lightly mottled tan, brown, olive or sometimes bluish-gray coloration over its entire body. The other morph has similar background coloration but has two dark stripes that begin on either side of the carapace and extend the length of the abdomen (see also Hay 1902, Bouchard 1978, Hobbs 1981). We raised juveniles of both color morphs in the laboratory and found that the color differences are maintained for at least 1.5 years (the longest we held them), although the dark stripes fade somewhat with age.
