Dziriblatta nigriventris Chopard, 1936b: 156 .

Lobolampra nigriventris: Chopard 1943: 33 .

Phyllodromica (Lobolampra) nigriventris: Morales Agacino 1948: 345 ; Princis 1971: 1115.

Diagnosis. In the male sex distinguished from Sculptoblatta prisca and other species by the different structure of T7; female distinguishable from S. prisca by the shape of the dorsal basivalvular sclerites, but hardly distinguishable from other species of the subgenus.

Description. Size. Length of pronotum in male 1.73–2.14 (1.98 mean) mm, in female 1.76–2.24 (mean 2.08) mm.

Male structures. For the description of T7 and its gland see under characters of the subgenus ( Figs. 9D , 10 A– C). Glandular pores present on T2–10, sparse on T2,3, numerous and dense on the remaining tergites ( Figs. 10A, B, E ).

Female structures. For the description of the genital sclerites see under characters of the subgenus ( Figs. 9O, P ).

Colouration. Similar in both sexes; ground colour yellowish, thoracal nota with variously sized and shaped dark spots, often fused to larger elongated markings, on the pronotum to a kind of a lyrate pattern, on meso- and metanotum to irregularly shaped longitudinal stripes; abdomen relatively dark, tergites anteriorly of the transversal ridge usually completely dark, dark area extending at up to seven positions into the posterior field as more or less broadly triangular patches, remaining surface with similar spots as on the thoracal nota; sternites mostly dark, with yellowish lateral margins ( Figs. 9 A–I, L–N).

Distribution. Northern end of the Middle Atlas mountain chain: Jbel Bou Iblane and surroundings (Fig. 29).
