Nola ezagutu

Females have red markings on both the top and underside of the abdomen, which no other African Latrodectus species has.1
Males have white markings on the underside of the abdomen, which darken with age.1
Egg sacs are large and smooth, bright purple when freshly laid, fading to shiny grey as they dry.1
Webs are not usually found outside the tree hollow. When present, they are typical hackle webs spreading out from the hollow.1

Askotan honekin nahasten da: Other African button spiders do not have the red markings on both the top and underside of the female abdomen, which is the main feature that sets this species apart.1

Kosk egiten badu

Garbitu koska eta jarri izotz-poltsa bat gainean minerako. Lortu mediku-laguntza mina handia bada, zabaltzen bada edo pertsona gaizki sentitzen bada.

Egon seguru

Ez ukitu, ez harrapatu eta ez zirikatu inoiz animalia basati bat, txikia izan arren, eta lo edo hilda dagoela badirudi ere.
Utzi tartea. Bat aurkitzen baduzu, egon lasai, egin atzera poliki eta utzi bere bidetik joaten.
Batek kosk egiten badizu: egon lasai, egon geldi, deitu zure larrialdi-zenbakira (112, 000, 911) edo joan ospitalera azkar. Gogoratu nolakoa zen, argazki batek laguntzen du.

Ez dabil zure atzetik. Pozoia janaria harrapatzeko edo bere burua babesteko erabiltzen du, eta askoz nahiago du ezkutatu. Seguru egoteari buruz gehiago

Datuak

It is believed to be the largest member of the button spider genus, Latrodectus.1

Its discovery was the first new addition to the genus in 28 years. Before this, 31 button or widow spiders were known, eight of them from Africa.1

Females nest in tree hollows and stumps higher above the ground than most other members of the genus.1

It was first found in 2014 in Tembe Elephant Park, but was only confirmed as a new species in 2019, after live specimens were collected from Phinda reserve.1

One female kept in a laboratory lived for two years until her natural death, and her offspring were also studied.1
