The orb-weaving spider genus Novakiella Court & Forster, 1993 (family Araneidae Clerck, 1757) is reviewed to include two species, N. trituberculosa (Roewer, 1942) (type species, Australia and New Zealand) and N. boletussp. nov. (Australia). Novakiella belongs to the informal, largely Australian ‘backobourkiine’ clade and shares with the other genera of the clade a single macroseta on the male pedipalp patella and a median apophysis of the male pedipalp that forms an arch over the radix. The proposed genus synapomorphies are the presence of a large basal conductor lobe expanding apically over the radix and the shape of the median apophysis, which extends into a basally directed, pointy projection. Males have an apico-prolateral spur on the tibia of the second leg that carries a distinct spine. Females have an epigyne with triangular base plate bearing transverse ridges and an elongate triangular scape, which is almost always broken off. The humeral humps of the abdomen are distinct. Novakiella trituberculosa build characteristic dome-shaped webs; however, the foraging behaviour and web-shape of N. boletussp. nov., currently only known from museum specimens, are not known.

澳大利亚和新西兰圆蛛属 Novakiella(Araneae,Araneidae)的回顾

圆织蜘蛛属 Novakiella Court & Forster,1993 年(Araneidae Clerck,1757 年)被审查为包括两个物种,三绦虫(Roewer,1942)(模式物种,澳大利亚和新西兰)和牛肝菌。十一月 (澳大利亚)。Novakiella 属于非正式的,主要是澳大利亚的“backobourkiine”进化枝,与该进化枝的其他属共享雄性触须髌骨上的单个巨齿和雄性触须的正中隆起,在基部上方形成拱形。拟议的属突触是存在一个大的基底导体叶在基部和正中骨突的形状上扩展,它延伸到一个基部定向的尖状投影。雄性在第二条腿的胫骨上有一个顶端前外侧骨刺,带有明显的脊柱。雌性有一个带有带有横向脊的三角形底板和一个细长的三角形花盆,几乎总是折断的。腹部的肱骨隆起明显。Novakiella trituberculosa 构建特征性的圆顶形网;然而,牛肝菌的觅食行为和网状结构。11月,目前仅从博物馆标本中得知,未知。
