Nephotettix cincticeps (Uhler 1896a: 292 )

Membracoidea : Cicadellidae
Diseases Transmitted
Rice tungro bacilliform virus Tungrovirus Virus
Rice yellow dwarf 16SrXI-A Phytoplasma

Described as Selenocephalus cincticeps Uhler.

N. cincticeps was first described as Selenocephalus cincticeps by Uhler (1896). Alternative names included Nephotettix bipunctatus and a form of N. apicalis, until Linnavuori named it N. cincticeps. Ghauri (1971) revised the genus and segregated nine species, most of which had previously been confused with N. cincticeps.

It is an important rice pest being a vector of rice tungro virus and rice yellow dwarf phytoplasma.

Distribution Map
(simplified continental distribution)
Geographical Distribution:
Asia

Recorded Distribution(s):
N. cincticeps is a more northerly distributed species in Asia than any other Nephotettix species. Known from Japan, China and Taiwan (Ghauri, 1971). Russian Far East (Anufriev & Emeljanov, 1988).

This species is common in Japan. It has been reported from Korea, Manchuria, Okinawa (Esaki and Ito 1954 [234]) and Formosa and Ryukyu Islands (Ishihara 1964 [390]). Records of oc¬currence in other parts of the Oriental region, Middle East, and Africa probably referred to apicalis. (Nielson, 1968)

Species Description

Length:
Length of male 4.30—4.50 mm., female 5.00—5.60 mm.

Colour:
General colour green to grey with brown or black band on tip of elytra in male. Crown light green with distinct black transverse line near anterior margin; pronotum with anterior half green, posterior half brown; scutellum green; elytra light green, broad brown or black band on apex in males; markings absent in females; green turns gray in old specimen.Males — head with black submarginal band between eyes, apical third of forewing black. Females — similar in coloration to many nigropictus females; submarginal band of vertex often not touching inner margins of eyes, forewings without dark markings.

Genitalia:
Pygofer with distoventral corner pointed, with one long spine and a group of 3-5 mm small spines below (Fig. B). Parameres with internal process curved and short in comparison with base of paramere (Fig. E). Aedeagus with shaft in ventral view constricted; apex in lateral view swollen (Fig. D); dorsal longitudinal carinae convex in lateral aspect with 5 pairs of spines located in middle of aedeagal shaft.

Species Diagnosis

The rounded head and markings in the males resemble those in nigropictus but may be easily separated from this species by the male genitalia, particularly the spine number (5 pairs) and the shape of the parameres. In coloration females may be confused with some N. nigropictus but the submarginal band is not fully extended between eyes and the inner margin of the clavus is never black. Males may sometimes resemble N. nigropictus but never have the inner margin of the clavus black.

The black markings of N. cincticeps are similar to those of N. parvus, a tropical Asian species, but the head is broadly rounded instead of pointed as in N. parvus. In cases where male N. cincticeps cannot be distinguished from other Nephotettix species by external morphological characteristics, they can be separated by examination of the genitalia. The aedeagus in males of N. cincticeps has five pairs of spines located in the middle of the aedeagal shaft, as opposed to eight in N. nigripictus and one in N. parvus. The shape of the paramere is also diagnostic, with the internal process curved.
