(1987) , and, judging from the original figures, also to D. antennalis ( Kapoor et al. , 1987 ) comb. nov. from southern India . Being morphologically hardly distinguishable from each other, the D. holosericeus species group is a good example of how challenging pipunculid taxonomy can be. The males of D. zardouei sp. nov. differ from those of the other species by a different sclerotization pattern of the gonopods and by the length of the phallus. The females can be separated by the shorter length of tergite 9 (piercer of ovipositor). Etymology The species is named in honour of Maryam Zardouei who collected the type series material. The surname is to be used as a noun in apposition.

Pulvilli longer than distitarsi. ABDOMEN. Ground colour dark. Tergite 1 with four to five strong lateral bristles, arranged in one row. Tergites1–5 with brown setae.Tergites1–2 gray pollinose laterally and dorsally, tergites 3–5gray pollinose laterally, extending onto dorsal surface along posterior margin. Tergite 5 symmetrical. LT35:WT5=1.5, WT5:LT5 =1.3 and T5R:T5L=1.0. Syntergosternite 8 dark, brown pollinose, without dorsal depression on side of right surstylus. LT35:WS8=2.5.

Genital capsule in dorsal view: epandrium dark, brown pollinose and wider than long (MLE:MWE =0.8). Surstyli brown, narrowly pale at apices, brown pollinose and rather symmetrical. Both surstyli with a blocky base and a broad finger-like projection at its apical inner corner, bent outward distally by 90°; base of right surstylus slightly wider than left surstylus ( Fig. 5G ). Genital capsule in ventral view: gonopods minute and symmetrical, with elongated regions of distinctly stronger sclerotization ( Fig. 5A ); phallus trifid, straight and short (almost reaches apex of surstyli), with a membranous nose at base ( Fig. 5B ); phallic guide narrow and straight, with two dorsolateral spines at the end of basal half on either side ( Fig. 5C ). Genital capsule in lateral view: epandrium without projecting lobe on either side. Both surstyli in basal half broad, in apical half narrowed to form a finger-like process which is bent towards the sternites by 90° ( Fig. 5 F–G).
