Micrathena sanctispiritus is a species from the genus Micrathena . [1] [2]
Orb-weaver spiders are members of the spider family Araneidae. They are the most common group of builders of spiral wheel-shaped webs often found in gardens, fields, and forests. The English word "orb" can mean "circular", hence the English name of the group. Araneids have eight similar eyes, hairy or spiny legs, and no stridulating organs.
Gasteracantha is a genus of orb-weaver spiders first named by Carl Jakob Sundevall in 1833. Species of the genus are known as spiny-backed orb-weavers, spiny orb-weavers, or spiny spiders. The females of most species are brightly colored with six prominent spines on their broad, hardened, shell-like abdomens. The name Gasteracantha is derived from the Greek gaster (γαστήρ), meaning "belly, abdomen", and akantha (άκανθα), meaning "thorn, spine". Spiny-backed orb-weavers are sometimes colloquially called "crab spiders" because of their shape, but they are not closely related to the true crab spiders. Other colloquial names for certain species include thorn spider, star spider, kite spider, or jewel spider.
Micrathena gracilis is a spider in the family Araneidae (orb-weavers), commonly known as the spined micrathena or castleback orbweaver. This spider spins a moderately large and very tightly coiled web. The spiders themselves are small and can be found to be anywhere from 4.2 mm to 10.8 mm long. Its venom is harmless to humans. M. gracilis is unique in appearance due to its large spiky abdomen and black and white bodies. Certain spiders of this species can also display a yellow color on the sides of their bodies. These spiders can be seen most active during the end of the summer and beginning of fall. M. gracilis is diurnal and are rarely ever seen active at night.
Micrathena, known as spiny orbweavers, is a genus of orb-weaver spiders first described by Carl Jakob Sundevall in 1833. Micrathena contains more than a hundred species, most of them Neotropical woodland-dwelling species. The name is derived from the Greek "micro", meaning "small", and the goddess Athena.
Argiope protensa, commonly known as the tailed grass spider or teardrop spider, is a species of spider in the orb weaver family, Araneidae. This species is fairly common and widespread in Australasia, but like many spider species, little is known of its ecology, biology, or life history.
Micrathena sagittata, also known as the arrow-shaped micrathena, is a species of spider belonging to the family Araneidae. It is found in the eastern United States and throughout Central America.

Triviella is a genus of small sea snails, marine gastropod molluscs in the family Triviidae, the trivias.
Micrathena mitrata, the white micrathena, is a species of orb weaver in the spider family Araneidae. It is found in a range from the United States to Brazil. The spider has a distinctive appearance with a shiny, black abdomen and spiky, yellowish-brown legs. Its body length ranges from 4 to 9 mm in females and 3 to 4 mm in males. The species is known for its elaborate web, which it uses to capture insects for food. Despite its fearsome appearance, Micrathena mitrata is not considered dangerous to humans and is generally regarded as a harmless spider.
Micrathena funebris is a species of orb weaver in the spider family Araneidae. It is found in a range from the United States to Costa Rica.
Micrathena lucasi is a spider in the orb-weaver spider family, Araneidae. The species belongs to genus Micrathena and was first named in 1864 by Eugen von Keyserling.
Pasilobus bufoninus is a species of spider in the orb-weaver spider family Araneidae, found in Taiwan and Indonesia.
Micrathena lepidoptera a species of orb weaver in the family Araneidae. This species has been found in Costa Rica and Colombia and is endemic to Sierras Nevadas of northern Colombia. Not much is known about this species, including its diet, life cycle, and reproduction. A study by Ivan F. Magalhaes and Alberto J. Santos saw members of the Micrathena group genetically tested to better organize the Micrathena and Chaetacis phylogenetic trees. This paper includes four synapomorphies for this species. These include: wrinkled booklung covers, epigynum with a pair of anterior apodemes, small copulatory openings that are concealed beneath lateral plates, and terminal apophysis that is fused to the embolus. The females of this species are distinct by having three compound spines on the each side of the abdomen, with a thoracic depression and dimples in the carapace and blunt spines on either side of the spinnerets.
Micrathena yanomami is a species of orb-weaver spider described in 2011. Its distribution includes French Guiana, Brazil, and Peru. The species was first described by arachnologists Ivan Magalhães and Adalberto Santos.
