Nilaparvata bakeri Stål

Described as Delphacodes bakeri Muir.

(Wilson & Claridge 1991)

Description & Identification

Macropterous male 3.7-4.2 mm, female 4.4-4.6 mm. Brachypterous male 2.5-2.8 mm, female 2.8-3.4 mm. (Nielson, 1968)

Male pygofer with spined process (Figs 3.13, 3.20) arising medially from ventral margin. Parameres bifurcate apically as in Fig. 3.15. Aedeagus as in Fig. 3.19. In the female valvifer VIII (lateral lobes in Mochida and Okada, 1979) is diagnostic in N. bakeri, being distinctly hook-like at the basal portion (Fig. 3.21). Some authors (e.g. Mochida and Okada, 1979) have used the character of an excavation of the median carina of the frons as being diagnostic. However, we consider this character to be rather variable and the genitalia of both male and female to be much more reliable.
