Figures 53–55 .

Chrysomyza anaglypha Séguy, 1941: 114 ; Physiphora anaglypha: Steyskal, 1980: 576 .

Material. Type. Holotype ♀: Niger: “env. d’Agadès, Nov. 1938 [white label], “Muséum Paris 1938-1939 L. Chopard” [blue label] (MHNP).

Diagnosis. This species can be easily differentiated from all other species of Physiphora by having entirely yellow fore tarsi. It is similar to P. meyi sp. n., P. obscura and P. opalizana sp. n. in having λ-shaped microtrichose area on the facial carina and densely rugulose, matt scutum and scutellum, differing from them by entirely rugulose postpronotal lobe, anterior portion of anepisternum and epistome (polished black in all other species). It is similar to P. meyi sp. n. and P. opalizana in having matt frons, clearly differing from the first also by entirely hyaline wing (with dark apical spot in P. meyi sp. n.).

Description: Head ( Figs. 54–55 ). Frons as long as wide, yellow, matt, sparsely and uniformly microtrichose. Microtrichose parafrontal spots poorly visible, round. Vertical plates black, with green sheen. Face with yellow antennal grooves and facial carina and dark brown, green shining lunule and epistome; with gray microtrichose antennal grooves and λ-shaped narrow mark on carina. Parafacial and gena yellow; gena 1/3 times as high as eye; parafacial with narrow white microtrichose stripe along eye margin. Occiput black, with brown area posterior of ocellar triangle and postgena; orbit between posterodorsal eye margin and row of black postocular setae with narrow white microtrichose stripe. Antenna yellow; flagellomere 1 rounded apically; arista yellow in basal 1/3, brown in the rest.

Clypeus brown to black, with greenish sheen. Palp brown to black, microtrichose. Mouthparts brown.

Thorax. Scutum and scutellum ( Fig. 54 ) black, almost uniformly densely rugulose, including antepronotum, postpronotum, notopleural triangle and pleura, with matt green to cyan metallic sheen. Mesonotal scutum without visible rows of setulae. Setae as in P. allomma Scutellum without fine setulae, but with 2 pairs of black scutellar setae.

Wing. Entirely hyaline, with pale yellow veins; cell r4+5 very narrowly opened, with the distance between R4+5 and M apices 0.1 times as long as crossvein r-m; vein M slightly arcuate; postero-apical extension of cell cup 1.4 times as long as vein CuA2+A1, and 1.8 times as long as transverse section of vein CuA2. Length: 2.6 mm.

Legs. Yellow except frmora brownish, fore tarsus entirely yellow.

Abdomen strongly shriveled in the holotype; tergites 1 and 2 with black setulae. Female terminalia: oviscape reddish yellow; not dissected.

Biology unknown.

Distribution: Niger.
