Dorymetaecus is a monotypic genus of Australian araneomorph spiders in the family Phrurolithidae, containing the single species, Dorymetaecus spinnipes. It was first described by William Joseph Rainbow in 1920,^[2] and has only been found on Lord Howe Island.^[1] Rainbow died in November 1919, shortly before publication of the work this species is described in.

Description[]

The holotype was found on Kentia palms, and only the female of this species is known. Its cephalothorax is 1.5 millimetres (0.059 in) long and 1 millimetre (0.039 in) wide. The opisthosoma is 2.1 millimetres (0.083 in) long and 4 millimetres (0.16 in) wide.^[2]

Cephalothorax obovate, broad, well arched, yellow, with two dark-brown wavy lines behind the eyes, and with black lateral margins, close to which are smoky-brown patches. Pars cephalica not raised, sloping gently forward, narrow in front, truncated, segmental groove faintly distinct; clypeus narrow. Pars thoracica sloping rearwards, radial grooves moderately defined; median stria short, distinct, lateral margins slightly reflexed; marginal band narrow. Eyes in two recurved rows of four each, close together, rear median ones widest apart; front row shorter, close to edge of clypeus; posterior eyes larger. Legs yellow, long, robust, bespined; first and second pairs longest and strongest; tibia i and ii armed with seven pairs of long, strong yellow spines, and meta-tarsi of same with four pairs; bases of spines large, black; spines on legs iii and iv short and weak. Relative lengths, 4, 1, 2, 3. Palpi concolorous, moderately long, armed with a few rather long spines. Falces yellow, short, arched, not strong; inferior ridge of each falx armed with two very small teeth, and the superior with two even smaller ones; fang short, weak. Maxillae short, robust, arched, yellow, apices inclined inwards, constricted near base. Labium concolorous, arched, short, broad, about as long as width of base; apex rounded. Sternum cordate, broad, yellow, arched, terminating obtusely between fourth pair of coxae. Abdomen ovate, arched, slightly overhanging base of cephalothorax, yellow; superior surface ornamented with smoky-brown markings. Epigynum a moderately large plaque, the margin of which is dark brown and raised. Spinnerets yellow, short; superior pair cylindrical, biarticulate, terminal segment shortest; inferior pair rather stout; coniform, biarticulate, apical segment minute, dome-shaped.^[2]
