Diagnosis
Posterior mesoscutal width 1.29 × (1.29) mesoscutellum width. Male genitalia: harpe finger-shaped apicoventrally and slightly broadened at apex in ventral, lateral and dorsal view; harpe/gvc index 0.28; ventromedial margins of harpes not touching at distoventral margin of gvc, ventromedial margin of harpe concave in basal two thirds, straight and diverging distolaterally in apical third; ventral margin of harpe straight, dorsal margin indistinct in basal part, concave in apical three quarters, lateral margin convex and oriented distomedially in basal two thirds, straight in apical third; genital length 1.57–1.71× (1.71) gvc width; Weber length 2.82–3.08 × (3.08) genital length.
Etymology
The species is named out of love for Maria Salden, the first author’s mother.

Female
Unknown.
Variation
ZFMK-HYM-00034461 is distinctly smaller and lighter.
Biology
Host unknown, specimens collected from leaf litter.
Distribution
Afrotropical: Kenya.
Remarks
Comparison with similar species The male genitalia of A. mariae sp. nov. are somewhat similar to those of A. sp. 1 and A. sp. 2 as all share apicoventrally finger-shaped harpes with a broadened apex in ventral, lateral and dorsal view. However, apart from this, A. mariae differs strongly in body and male genitalia characters from A. sp. 1 and A. sp. 2.
Condition of type material
Holotype is immaculate.
