Phthorima picta ( Habermehl 1925, Phthorimus )

Phthorima gaullei Seyrig 1928

Diagnosis. Fore wing length 3.8–4.4 mm. Antenna in females with 16 to 17 flagellomeres, in males with 17 flagellomeres and with narrow, long tyloids on flagellomeres 7 to 10/11. Face with a deep sulcus between compound eye and base of mandible. Clypeus with a subbasal impression, rendering the apical three-quarters concave. Propodeum with carination complete, but some carinae often partly replaced by strong rugae. Second metasomal tergite 1.45–1.55 times longer than wide, with irregular sculpture and punctures, third tergite smooth with inconspicuous background sculpture.

Colouration of females. Antenna black. Head and mesosoma black, face with a large yellow central face patch which is often confluent with yellow clypeus, yellow on mouthparts, hind corner of pronotum, tegula, large shoulder mark and supper mesepimeron; scutellum with a yellow margin or entirely yellow. Legs orange, coxae orange, fore and sometimes mid coxae yellow; femora orange; hind tibia whitish with a brown apex and subbasal marking, hind tarsus dark, first tarsomere white basally. Metasoma black.

Colouration of males. As in females but with yellow ventrally on antenna, entire face, propleuron, large shoulder mark with the inner corner extended over part of mesoscutum, subtegular ridge, varying proportion of epicnemium and mesosternum, and a broad stripe on lower mesopleuron. Fore, mid and sometimes hind coxae largely yellow.
