Girault (1913b, p. 166), as Signiphora reticulata (original description).

Dahms (1986, p. 474): notes on type material; note on placement as Matritia (Girault unpublished notes).

Type material. Holotype female, QM Hy 1281 (T4408) , on a slide that also contains a coverslip fragment with the type of Australaphycus albioviductus Gir. , labelled ‘Queensland Museum. TYPE | Hy/1281 | ♀ || Australaphycus albioviductus Gir. , Type ♀ || Signiphora reticulata Girault , ♀ type. Sweeping, forest, Ayr, Q., 6 Apr., 1912 | 4408 ’.” The specimen had the head removed, broken in many pieces, but the remainder of the body is preserved, one fore leg missing. Dahms (1986) describes three slides located at QM, one with the holotype and two with multiple individuals from Mackay [Queensland], labelled as Signiphora Matritia reticulata (Girault) (not type material) and all with heads and other parts dissected; he also states that the number T4408 was a duplicate QM accession number for the holotype and had been cancelled.
