Alaxchelicera ordinaria Butler , 1932. New Synonymy.

The holotype male is mounted on a slide (Figs 1-3) and the somatic morphology is therefore not easily observed. The prosoma is compressed and cracked, and one leg and several leg articles are missing. The left pedipalp is also missing. However, the left postocular sulcus is clearly present (Fig. 2, arrow) and the male pedipalp has a morphology that agrees with Microctenonyx subitaneus (O.P.-Cambridge, 1875), including a long prolateral tibial apophysis, an S-shaped embolic division (radix and embolus) with a distal hook, a suprategulum ( SPT) with a long slender blunt distal suprategular apophysis ( DSA) as well as a small knob-shaped marginal suprategular apophysis ( MSA). For comparison see Wiehle (1960: figs 851, 852) and Miller (2007: figs 123 A-C).

Note on type material: The holotype male from Lorne , Victoria, Australia (catalogue number K-106 ) is deposited at the Museum Victoria (Melbourne). The slide has two labels: one with the text "Type - S. Butler Melbourne" and the other with the text "Male Alaxchelicera ordinaria K-106."
