Species identification of spiders in coastal rural areas of eastern Fujian

This paper is the type identification of some spiders photographed in my hometown in 2008, which was taken in the coastal countryside of eastern Fujian. According to the matching degree between the information on the Internet and the spider in the photo, the species with the highest matching degree is selected as the species type of the spider in the photo. Due to the lack of data, some species are only identified as genera or families. Each photo gives a reference for identification, for readers to consult)

Introduction: Salticidae is the largest family of Araneae, also known as "frog" (pronounced "gap"), with more than 5,000 species in the world. Most of them are less than 15mm in length. Short, rough and flat body, short and powerful footsteps, good at jumping, hence the name. Distributed all over the world, there are many kinds of tropics and subtropics. The life style of jumping spiders is generally to catch insects by jumping. Jumping spiders also spin silk, but they don't weave webs. Jumping spiders spit out spider silk as a "safety rope" when jumping or falling from a height. The most obvious features of jumping spiders are the four eyes at the front end of the head and chest. Of these four eyes, two are particularly big and the other two are relatively small. Jumping spiders have the best eyesight among invertebrates, so they often look around with their heads raised.

Chinese name: Brown-striped Flying Tiger

Latin scientific name: Plexippus Paykulli (Audouin, 1826)

Introduction: The spider in the picture below is about 9mm in size and is the female spider of the Brown Striped Flying Tiger. There is a great difference in appearance between the female and male spiders of the brown striped flying tiger, which is also the common feature of the jumping spider family. As shown in the following figure, the female spider of the brown-striped flying tiger is brown, with dark brown on both sides of the head and chest edge near the abdomen, light brown fluff on the abdomen edge, a light-colored wide longitudinal band in the middle of the abdomen, and two obvious white spots on both sides of the longitudinal band. The brown striped flying tiger is a common spider, which moves on the wall at home. For example, in the photo, it just leans against the clothes that are drying.

Chinese name: Flying Wolf.

Latin scientific name: Philaeus (Thorell, 1869)

Introduction: The body length of LEPIDOPTERA insects is 7- 12mm, and the appearance of male and female is quite different. The spider in the photo has the same head and shape as the black-footed spider (176 1), but the color is different, so it belongs to the genus black-footed spider. The spider's abdomen markings in the photo have not yet formed, and the proportion of head, chest and abdomen is also different from other jumping spiders. It is speculated that the spider in the photo may be a wild silkworm.

Introduction: Aedes includes 6 genera, 102 species, also translated as Aedes. It belongs to the order Araneae. The head and chest are round, densely covered with white hair and surrounded by two linear rings. Each eye grows on the back, and the abdomen is oval and dark grayish brown. Cynanchum auriculatum is very small, and it is woven into a flat spider web in the gap between walls and similar spaces. The biggest feature of Pulsatilla is the protrusion in the center of the head and chest (such as the black protrusion in the center of the spider's head in the photo), which is why it belongs to Arachnoidea.

English name: boat-shaped quasi-wall money

Latin scientific name: Oecobius Navus (Black Wall, 1859)

Introduction: This is a boat-shaped quasi-wall money taken in Fujian. Baidu Encyclopedia's picture of the boat-shaped quasi-wall money is wrong. The Latin scientific name can correspond to the spider in the photo, and the Chinese name of this Latin scientific name on Wikipedia is the boat-shaped quasi-wall money, which is subject to Wikipedia. Baidu Encyclopedia's ship-shaped quasi-wall money is distributed globally, and domestic distribution does not include Fujian, which is doubtful.

Chinese name: white-fronted spider

Latin scientific name: Heteropoda (Linnaeus, 1767)

Introduction: White-fronted Spider, Heteropoda Spider, commonly known as Tall Spider, Okumo, malone ride, Aralia elata, Aralia elata. The white-fronted spider is the biggest spider in the room. It can't weave a web. It usually likes to hide in the gap between the roof and the cupboard during the day and come out for food at night to catch cockroaches or flying insects. The body length is about 20 mm ~ 30 mm, and the total length (including feet) is about 100 mm ~ 130 mm, with yellow-gray hair all over the body and a white horizontal band in the forehead area, which is the origin of the name of the white-fronted spider. There is a big black V-shaped stripe on the carapace of the male spider, but the female spider is darker and bigger without this stripe. The white-fronted spider is Nocturnal Animals, and likes to haunt in a slightly dark place.

Introduction: Zoropsidae is a rare spider, a bit like a tarantula, so it is also called a false tarantula. The difference between escape spiders and tarantulas is that their eyes are arranged in two rows of equal size. Aphidae includes 25 species 18 genera. This photo is the closest to the genus Titiotus of Aphidae (the color, claws and overall appearance match, the eyes do not conflict within the recognizable range of the photo, and the hair on the body surface does not match the stab wound on the leg), but no highly matched species type is found. According to Wikipedia, Titiotus has 16 species, all in the United States, but this photo was taken in rural Fujian, and whether it belongs to Titiotus needs further confirmation. From the appearance, this spider is easy to be judged as a tarantula, but in the online materials (mainly Wikipedia and bugguide), the tarantula does not have this kind of red spider; Arachnida has this kind of red spider, but the head and chest of Arachnida are wide and flat, and the abdomen is relatively small, so it is also excluded; The only choice left is the runaway spider family. All of the above are based on the information I found on the Internet. If you have friends who know better, you can tell me. I would appreciate it.

Introduction: Echinoventral Spider is an animal belonging to the genus Echinoventral Spider of Arachnidae, which is distributed all over the world and is the slowest spider. The six spines in the hard abdomen of the Echinoventral Spider are usually brightly colored. The special pattern that looks like a human face is actually a "rib point" formed at the junction of spider muscles and shells.

Chinese name: Echinoventrus Kuhn.

Latin scientific name: gasteracatha kuhli(C. l. Koch, 1838)

Introduction: Echinococcus Et is called Echinococcus Guggenheim in Taiwan Province Province. A vertical circular net will be formed between branches, and the spider itself will always live in the center of the net. There is a net on the back of the spider below, which is just on the six spines of the Echinoventral Spider. Is this a web woven by the larvae of Echinoventral Spider, or is there another smaller spider weaving a web on its back? Please explain if you know.
