Taxonomy 
Maddisonia gen. nov. 
Etymology. The name is proposed for Prof. Wayne 
Maddison (University of British Columbia, Vancouver), 
the world authority in salticid taxonomy, biogeography and 
evolution. The name is feminine in gender. 
Type species: Maddisonia richardsoni sp. nov. 
Diagnosis. Small/tiny spiders. Embolus large, cork-screw¬ 
like. In some species a projection at the embolus’ base 
present. Seminal reservoir not meandering, tibial apophysis 
long, single or bifurcate, sometimes with a ventral protrusion. 
First legs stout, 4th legs longer than 3rd ones. 
Description. Spiders below 3 mm long. Cephalothorax 
pear-shaped, widest at the fovea level, rather low, elongate, 
posterior thoracic slope starts at 2 A of thorax’s length. Fovea 
well behind PFE, in the middle of cephalothorax. Clypeus 
very narrow. Abdomen ovoid, spinnerets not distinctive. 
Chelicerae with single or two-cuspidate teeth on the posterior 
margin. First legs stout, with 3 and 2 pairs of ventrolateral 
spines on tibiae and metatarsi, respectively. Other legs 
rather delicate, not distinctive, legs 4 longer than legs 3. All 
legs, especially 2-4 with dark and light bands on particular 
segments. Palpal organ’s embolus large, cork-screw-like, 
sometimes with a small projection (p) at its base. Sperm duct 
(sd) not meandering, tegulum ovoid or with lobe (tl). Palpal 
tibial apophysis long, sometimes bifurcate, with or without 
additional protrusion. Females not known. 
Relationships and distribution. Due to the unique male 
genitalic structure, the taxonomic position of this enigmatic 
genus is unclear—at least as long as females are known. The 
particular species are recorded from single localities (Fig. 
5), thus the predictions of their potential distribution are not 
possible at this stage. 
Maddisonia richardsoni sp. nov.

Etymology. The species’ name is proposed for Prof. Barry 
Richardson (Australian National Insect Collection, Canberra) 
in recognition of his research on salticid taxonomy.

Robert Whyte, Australian naturalist, arachnologist and 
photographer.

Diagnosis. Tibial apophysis bifurcate with additional ventral 
protrusion (see arrow at Fig. 4C). Tegular lobe pointed, 
embolus’ base with projection (see arrow, Fig. 4C).

Maddisonia berbekai sp. nov. 
Figs 3, 4E,F

late Mr Maciej Berbeka, distinguished Polish mountaineer, 
who died during a pioneering winter ascent of Broad Peak 
in Karakoram on 6 March 2013.
