Following the original classification of Tamaricella Zachvatkin as a subgenus of Helionidia Zachvatkin some species of the former have been described as the latter by Russian authors and these species are omitted from the review. Helionidia notata Ahmed et Khokhar, 1971 and H. dumurae Ahmed et Samad, 1972 belong to other genera. Helionidiasobrina Dlabola is poorly illustrated (see Figs 104-107 in this paper) and it is impossible to figure out the genuine characters of this species; it could belong to the genus Tamaricella Zachvatkin as well. The following groups can be distinguished within the genus Helionidia Zachvatkin (basing mainly on paramere and penis structure). Group H. allaeri: allaeri, cicadulosa, dworakowskae, rubrata Group H. ahua: ahua, nasuta Group H. biplagiata: biplagiata, punctulata, talhouki Group H. karachiensis: karachiensis,rubra,viridula Group H. himyarita: himyarita, irina, kongica, laskowskii, nigra, ornata Group H. longifabű bomansi, longijdlx, quadrimaculata Group H. cornuta: cornuta,fujara,nigrella,ochrata Group H. acutivertex: acutivertex, jamtara, zelena Group H. fuscoviridis: fuscoviridis, hirsuta, kosa, lutea, uczka, ushae, wag a, zorba, xantha, xenia. The group of H. juscoviridis deserves special attention because of its distinctive characters and distribution. It can be characterized by the pale colouration on the upper side of the head and thorax, vertex produced in the midline and a white streak on the fore wing. The streak is parallel to the costal margin occupying part of m and part of r cell up to the distal end of the wax-field. Females in this group of species have vertex more produced and face much darker than males. In male genitalia the characteristics are the slim paramere with small apex, the often laterally compressed penis stem and the pygofer process usually of a fine shape. Pigmentation and shape of 7th abdominal sternite of the female show good distinguishing characters but the best way to examine these features is in a microscopic slide. Helionidia acutivertex (Ramakrishnan et Menon, 1974) (Figs 1-4) Zygina acutivertex Ramakrishnan et Menon, 1974 India: Delhi (Ramakrishnan and Menon 1974). The type-series has been examined in 1991 (Pusa Collection, IARI, New Delhi). The holotype, an intact male, is yellowish with a greenish tint and no dark markings on vertex, its anteclypeus is not infuscated either. The paratype male, the specimen which was dissected and illustrated at the original description, has dark markings on vertex and pale anteclypeus; the paratype female is coloured on its upper side as the holotype but its anteclypeus is blackish-brown at the tip and brown up to the half of its length; the allotype female is similar, with its whole anteclypeus blackish-brown and base of frontoclypeus brownish. Helionidia ahua Dworakowska, 1981 Niger: Tahoua - In Waggeur (Dworakowska 1981b)*. Helionidia allaeri Dworakowska, 1981 Zaire: Lulua, Kapanga (Dworakowska 1981b)*.
