Diagnosis. – A medium sized species; face entirely shining black; postpronotal lobes and notopleura yellow; scutum shining black; medium width lateral and narrow medial postsutural vittae present; a yellow spot anterior to mesonotal suture; mesopleural stripe reaching midway between anterior margin of notopleuron and anterior npl. seta dorsally; scutellum yellow; wing with a narrow dark fuscous costal band expanding slightly across apex of R 4+5 and broad dark fuscous cubital streak; cells bc and c colourless; microtrichia in outer corner of cell c only; abdominal terga almost entirely dark fuscous to black with, in some specimens, small redbrown to dark red-brown spots posterocentrally on terga III and IV and with bright orange-brown to fulvous shining spots on tergum V.

Attractant. – Cue lure.

Distribution. – China, Malaysia. New record for Bhutan.

Hosts. – No known record.

Remarks. – Bactrocera (Zeugodacus) atrifacies (Perkins) belongs to the scutellaris complex and particularly the group with 4 sc. setae. It differs from other species in this group in possessing an entirely black face. In facial colour, general leg colour patterns and terga III-V mostly dark fuscous to black, it is similar to Bactrocera (Zeugodacus) diaphora (Hendel) but the latter possesses two sc. setae.

One specimen in UQIC with the following labels is not the type of B. atrifacies – “ Pahang FMS, Kuala Teku 500’, Dec 6 th 1921, H.M. Pendlebury”, “ TYPE ”, “ Zeugodacus maculipennis Dol. det. F.A. Perkins”, “ Dacus (Zeugodacus) atrifacies (Perkins) , poss. as limbipennis Macq. From Bukit Kuta, Selangor ”. This is a specimen of Bactrocera (Zeugodacus) caudata (Fabricius) and the label data are not in agreement with those recorded by Perkins (1938) for B. atrifacies . It is not a pest species.
