The Genitalia of the Auchenorhynchous Homoptera

Postembryonic development of reproductive systems in Empoasca fabae (Harris) (Homoptera:Cicadellidae)

“…The development of the external genitalia of E. fabae mainly corresponds with that described by Snodgrass (1957) and prominent papers dealing with the development of Homoptera-Auchenorrhyncha by Kershaw and Muir (1922), Pruthi (1925), George (1929), Metcalf (l932), Dupuis (19^9) and Qadri (194$). The proximal one-third of the male genital plate rudiments is covered by a common cuticle and the distal two-thirds of each rudiment is a free lobe.…”

“…These extend posteriorly to the distal end of the ninth segment and completely cover the phallic rudiments. Kershaw and Muir (1922) observed in P. spumarius that the sexes of second-instar nymphs could be differentiated and that by careful exami nation of prepared specimens they could, be separated in first-instar nymphs. Pollard (1962) reported distinguishing characteristics similar to those of E. fabae for the fifth-instar nymphs of the cicadellids, Oncometopia undata (F.) and 0. nigricans (Walker).…”

The morphology of the male genitalia of Abricta ferruginosa (Stål) (Homoptera: Cicadidae)

“…In life, whole aedeagus exposed, lodged in a groove on ventral surface of tenth sternite and held in position by a pair of ventrolateral toothed sclerotised lobes. It will be seen from the above that the male genitalia of the Cicadidae have not been described in sufficient detail by workers like Crampton (1920, 1922), Pruthi (1925, Myers (1928), Kershaw and Muir (1922) and by recent authors. Although Apgar (1887) included drawings of both the extended and retracted aedeagus, he failed to interpret correctly the various parts.…”

“…in both the contracted and the extended condition but his interpretation of the various parts is inadequate, and unfortunately later hemipterists did not study cicadid genitalia to a degree comparable to this. Thus Kershaw and Muir (1922) simply emphasised that the male genitalia "were very distinct" from those of other Homoptera and pointed out that "in some Cicadidae the aedeagus was complex and trilobed". Similarly Pruthi (1925) examined the aedeagus of Abricta curvicosta Germ.…”
