Sigalphinae Haliday, 1833

Subfamily Sigalphinae Haliday, 1833

This subfamily is not large and includes only eight known genera with about 50 described species ( Yu et al. 2016; Sharkey et al. 2019). The tribal composition of this subfamily is not settled. Van Achterberg & Austin (1992) suggested here four tribes, Acampsini, Minangini, Sigalphini and Afrocampsini . Later the tribe Afrocampsini was transferred to the subfamily Acampsohelconinae ( van Achterberg 2002) , and the tribe Pselaphinini (former subfamily Pselaphininae ) was added to the subfamily Sigalphinae ( Quicke et al. 2008) . However, Quicke et al. (2008), based on providing molecular phylogenetic and morphological analysis, suggested already retaining in Sigalphinae only two tribes, Sigalphini and Pselaphinini .

The genus Malasigalphus van Achterberg & Austin was included together with Afrocampsis van Achterberg & Quicke in the tribe Afrocampsini . However, after transferring the latter genus to the subfamily Acampsohelconinae , based on molecular and morphological data, Malasigalphus was preserved in Sigalphinae-Sigalphini ( Quicke et al. 2008; Sharkey et al. 2019).
