Taxonomic notes.

This dark-brown species has brown-banded yellowish legs and hyaline wings (Fig. 18A, B ). It resembles A. taylori and A. pallipes , but can be distinguished from the former based on the longer, stronger hind tibial spur and presutural acrostichal setae, and from the latter based on characters described in the taxonomic notes for A. pallipes . This species does not have any immediately distinctive diagnosable character sets based on existing descriptions but can be identified based on the provided key. Chaetotaxy as observed: 2 vibrissae; 3 strong decussate interfrontal setae; 2 postpronotal setae; 2 scapular setae; 1+1 notopleural setae; short weak reclinate biseriate acrostichal row; 1+3 dorsocentral setae; 1+1 supra-alar setae; postalar and intrapostalar setae present; missing/indistinct prescutellar setae; scutellum with 1 discal setula; katepisternal seta missing/indistinct. Original description and subsequent taxonomic note in Suppl. material 1.
