Geopsammodius
tiny sand-loving scarabs
Geopsammodius is a genus of aphodiine dung beetles comprising approximately nine described species, all described or revised by Skelley in 2006. The genus was established by Gordon & Pittino in 1992. Species are found in sandy habitats in North America, with several bearing common names referencing their small size and sand-dwelling habits.
Geopsammodius morrisi
Geopsammodius morrisi is a small scarab beetle in the subfamily Aphodiinae, described by Paul Skelley in 2006. It belongs to a genus of psammophilic (sand-dwelling) beetles within the tribe Psammodiini. The species is known from a limited number of records in Florida, USA. Like other members of its genus, it is likely associated with sandy habitats, though specific ecological details remain poorly documented.
Geopsammodius relictillus
relictual tiny sand-loving scarab
Geopsammodius relictillus is a small aphodiine dung beetle in the family Scarabaeidae, described from Florida in 1991. The species epithet "relictillus" refers to its relictual status, suggesting it may represent a remnant population of a formerly more widespread group. It belongs to the tribe Psammodiini, whose members are commonly known as sand-loving scarabs due to their association with sandy habitats.
Geopsammodius unsidensis
Geopsammodius unsidensis is a species of aphodiine dung beetle in the family Scarabaeidae. It was described by Skelley in 2006. The species is known from North America, with records from Texas. As a member of the tribe Psammodiini, it is associated with sandy habitats.
Leiopsammodius
Leiopsammodius is a genus of aphodiine dung beetles in the family Scarabaeidae, established by Rakovič in 1981. The genus contains more than 40 described species. Members of this genus belong to the tribe Psammodiini, which are often associated with sandy substrates. As with other aphodiine dung beetles, species in this genus are likely involved in the decomposition of organic matter.
Neopsammodius interruptus
Neopsammodius interruptus is an aphodiine dung beetle in the family Scarabaeidae. The species was first described by Thomas Say in 1835. It is known from multiple states across the United States.
Neopsammodius quinqueplicatus
Neopsammodius quinqueplicatus is a species of aphodiine dung beetle described by Horn in 1871. It belongs to the family Scarabaeidae and is part of the Psammodiini tribe, which comprises beetles often associated with sandy habitats. The species occurs in both Nearctic and Neotropical regions.
Neopsammodius werneri
Neopsammodius werneri is a species of aphodiine dung beetle in the family Scarabaeidae. It was described by Cartwright in 1955. The species occurs in both Central America and North America, with records from the southern United States (Texas) and several Mexican states including Chiapas, Oaxaca, and Veracruz, as well as Honduras. As a member of the tribe Psammodiini, it is associated with sandy habitats.
Odontopsammodius
Odontopsammodius is a genus of aphodiine dung beetles in the family Scarabaeidae, established by Gordon and Pittino in 1992. The genus comprises approximately 12 described species. These beetles belong to the tribe Psammodiini, a group associated with sandy habitats. The genus is distributed in the Neotropical region.
Odontopsammodius cruentus
Odontopsammodius cruentus is a small aphodiine dung beetle in the family Scarabaeidae. It is distributed across parts of North America and South America, with records from the southeastern United States and Argentina. As a member of the tribe Psammodiini, it is associated with sandy substrates. The species was described by Harold in 1867.
Parapsammodius bidens
Parapsammodius bidens is a small aphodiine dung beetle in the family Scarabaeidae. It belongs to the tribe Psammodiini, which includes many sand-dwelling species. The species was described by Horn in 1871 and is known from scattered records across the southeastern United States, Caribbean islands, and Puerto Rico. Like other members of its tribe, it is likely associated with sandy substrates and decomposing organic matter.
Platytomus longulus
Platytomus longulus is a small aphodiine dung beetle described by Cartwright in 1948. It belongs to the tribe Psammodiini, a group often associated with sandy or loose substrates rather than dense dung. The species occurs across a broad geographic range spanning the southeastern United States and much of South America.
Platytomus notialis
Platytomus notialis is a small scarab beetle in the family Scarabaeidae, subfamily Aphodiinae. The species was described by Cartwright in 1948 and is native to the Nearctic region of North America. It belongs to the tribe Psammodiini, a group commonly associated with sandy habitats. Records indicate presence across multiple U.S. states in the central and eastern regions.
Pleurophorus caesus
Pleurophorus caesus is a small aphodiine dung beetle in the family Scarabaeidae. It has been recorded across a remarkably broad geographic range spanning the Palearctic, Nearctic, Neotropical, Afrotropical, and Madagascan regions. The species belongs to the tribe Psammodiini, which are often associated with sandy or loose substrates. Its widespread distribution suggests either human-mediated dispersal or an underappreciated native range, though this remains unresolved.
Psammodius pierottii
A small scarab beetle in the subfamily Aphodiinae, described from the Mediterranean region in 1979. The species belongs to a genus of sand-dwelling beetles typically associated with sandy substrates. It has been introduced to North America, with established populations in Quebec, Canada.
Rhyssemus puncticollis
Rhyssemus puncticollis is a small dung beetle species in the family Scarabaeidae, first described by Brown in 1929. The species has been recorded from both the Palaearctic region (central and eastern Europe) and the Nearctic region (Ontario, Canada), indicating a transatlantic distribution. It belongs to the tribe Psammodiini, which typically includes species associated with sandy or psammophilous habitats. The specific epithet 'puncticollis' refers to punctation on the pronotum.
Tesarius oregonensis
Tesarius oregonensis is a species of aphodiine dung beetle in the family Scarabaeidae. It was described by Cartwright in 1955. The species is found in western North America, ranging from British Columbia, Canada southward through Oregon to California. As a member of the subfamily Aphodiinae, it is associated with dung and decaying organic matter. Very little specific information has been published regarding its biology or ecology.
Trichiorhyssemus riparius
Trichiorhyssemus riparius is a small aphodiine dung beetle in the family Scarabaeidae, first described by Horn in 1871. It belongs to the tribe Psammodiini, a group commonly associated with sandy habitats. The species is known from the southwestern United States.
