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).
