Malkaridae
Malkara sp.
The Malkaridae are one consisting of 10 species spider family of the order of spiders. It was first described in 1980 by Davies. Its distribution area extends across Australia, Tasmania and New Zealand. It also occurs in Chile.
Features
In terms of color the Malkaridae species are characterized by an orange from red to dark body, centered sometimes a dark pattern can be seen. The oval abdomen ( tummy) has a epigastric furrow on which the openings of the anterior book lungs sitting. There also are the openings of the entelegynen genitals. The female reproductive organs consist of a simple Epigyne with one or two openings. Here are the two, located in the interior spermathecae, a large distance from each other. Are the six spinnerets at the rear underside of the abdomen. They are surrounded by a sclerotized ring. The Colulus is either missing, or is large and sclerotized. While the posterior spinnerets pair consists of two segments, the average very small. The front pair has a Stridulationsorgan in the middle. The connection between the abdomen and cephalothorax, the so-called pedicle is surrounded by a front serrated and notched Scutum. On the oval carapace is located at the front of the subfamily Sternodinae a small elevation on the eight eyes sit. The subfamily Malkarinae this area is flat. The slightly longer than wider sternum on the ventral side has the shape of a shield. The thin jaw claws ( chelicerae ) has no lateral condyle. While located on the rear edge of two to four teeth, it is on the front edge only a maximum of two.
System
The family consists of two subfamilies and four genera.
- Makarinae Malkara
- Carathea
- Chile nodes
- Most nodes
Phylogenetically the Malkaridae Mimetidae are compared as a sister taxon. This group, in turn, is seen as a sister group of Paurospinata. The complete cladogram to the level of true spiders is presented below:
