description: Aconurella Ribaut
Remarks. Although this genus was not previously recorded from Pakistan, one species (indica) described from Pakistan and India in Cicadula by Pruthi (1930) and two other species described from Pakistan (karachiensis and lobata) in Chiasmus by Ahmed et al (1988), belong in the genus and are considered to be junior synonyms of the widespread A. prolixa (Lethierry), previously recorded from Europe and Africa (Nast, 1972). Despite the poor original figures of the latter two species their ocelli are shown as marginal (as in Aconurella) whereas they are dorsal in Chiasmus (compare Figs 9 a and 10a), and the original figure of the aedeagus is as in Aconurella species (Figs 9 k-m). Therefore these species were not compared to Aconurella species but to other Chiasmus species and distinguished from them based on the male pygofer. Also, for A. lobata a continuous pygofer comb is figured, as found in Aconurella prolixa and although in A. karachiensis this comb is not described or figured the pygofer figure appears to us to be incorrectly drawn in its posterior part. The aedeagal figures of both species also match A. prolixa. The head markings in A. prolixa are variable (see Figs 9 a–d) and we have seen examples of this species with vertex markings similar to the original figures of lobata and karachiensis. Therefore taking the above similarities into consideration we conclude that the latter species are junior synonyms of A. prolixa. After examination of paratypes of A. neosolana Rao & Ramakrishnan (BMNH), described from India, we also consider this species a synonym of A. prolixa (see below). In addition to indica, dealt with above, three other species of Aconurella occur in India, i.e., A. solana Ghauri, A. montana (Distant) and A. erebus (Distant) (= A. montanus macropterous (Pruthi), synonymised by Ghauri, 1974: 555). Of these, at least one (A. erebus) appears distinct from A. prolixa based on its discontinuous pygofer comb.

Cicadula indica Pruthi. Syn. nov.

Material examined. Pakistan: holotype 3 (genitalia only), paratype 3 of Chiasmus karachiensis, no data; 53, 23Ƥ, Mithi, 7.viii.07. India: 13, 2Ƥ, Raghubendra, Nagar (A P), 13.v.1987 (paratypes of A. neosolana) (BMNH).
Remarks. Specimens were compared to the figures given by Ribaut (1952, figs 99–105). A specimen from Uzbekistan, Tashkent (BMNH) is also figured (Fig. 9 l) to show the similarity of the aedeagus from both regions. See also generic remarks.
Cicadula indica was described from Murree and Dalhousie Hills, Punjab and throughout India. The original figures and those of Pruthi’s material by Datta (1972) are good enough to place this species as a synonym of prolixa.
Chiasmus lobata was described from a holotype male and one paratype, from: Karachi, grass, 10.xi.1985 (ZMUK); no type specimens could be found.
Chiasmus karachiensis was described from the holotype male and paratype from: Karachi, grass, 1.xi.85, Qadeer (ZMUK). Paratypes are also present in the BMNH (see Material examined).
