ALLANAGRUS Noyes & Valentine, 1989

( Figs 10–20 )

Allanagrus Noyes & Valentine, 1989: 22 . Type species: Allanagrus magniclava Noyes & Valentine, 1989 , by original designation.

Diagnosis. Face with faint, partly incomplete subantennal sulcus extending from each torulus towards mouth margin ( Fig. 10 ); ocelli not delimited by stemmaticum; mandible with ventral tooth separated by deep notch from wide, apically serrate upper tooth (in one described species) ( Fig. 10 ) or, apparently, with 3 equal teeth (in another species); female antenna with clava 3-segmented or possibly 2-segmented (not clear so genus is keyed using both features) ( Figs 11 , 17 ); scutellum with campaniform sensilla abutting anterior margin of scutellum in one species ( Fig. 14 ) or well separated from it in another species ( Fig. 19 ); frenum entire; ovipositor and sheaths not extending forward under the mesosoma.

Discussion. Allanagrus belongs to the Anagrus group of genera, as previously classified by Noyes & Valentine (1989) and Lin et al. (2007). In the Afrotropical region the Anagrus group also includes Anagrus , Dorya , Omyomymar , Paranaphoidea and Schizophragma . Among these, Allanagrus and Paranaphoidea both have the clava 3-segmented though a species of Allanagrus with clava apparently 2-segmented ( Fig. 11 ) is tentatively included in the genus. If correctly placed the corresponding male would be the first recorded for Allanagrus . The single known male in the Afrotropical region has the flagellum 10-segmented. Afrotropical Allanagrus species have the scutellum with a minute scutellar seta at its posterolateral angle, midway between the anterior and posterior margins. This seta is in addition to the axillar seta and occurs in several other genera inside the group, e.g., Dorya or outside the group, e.g., Platystethynium .

Afrotropical hosts. Unknown.
