Genus: Chinavia

Name

Chinavia runaspis (Dallas, 1851)Wikispecies linkPensoft Profile

Remarks

Adults of Chinavia runaspis havegeneral body color light green to dark green, with reddish orange color on the margins of mandibular plates, pronotum, basal third of hemelytra and connexivum (Schwertner and Grazia 2007[1]). Chinavia runaspis is recorded for Venezuela, Suriname, Colombia, Brazil (Amapá, Pará, Minas Gerais, Rio de Janeiro, São Paulo, Santa Catarina, Rio Grande do Sul), Peru, Paraguay and Argentina (Schwertner and Grazia 2007[1]). The morphometric parameters of nymphal instars are shown in Table 5.

First instar

(Fig. 20). Body round and convex, surface without punctuation. General coloration dark brown to black. Head conical and strongly declivent. Clypeus with apex obtuse, length subequal to that of mandibular plates, these subtriangular shaped. Ocelli absent. Diameter at eyes smaller than the base of clypeus. Antennae black, intersegmental areas light brown; antennal segments covered by few hairs sparsely distributed. Antennal segment I shortest and antennal segment IV longest. Antennal segments III and IV subequal in size. Rostrum black, slightly surpassing the mesocoxae. Thorax predominantly dark brown, with a large, rounded,orange macula, which extends from middle of the head to the posterior margin of mesonotum. Legs black, denser hairs on tibiae and tarsus; tarsi two-segmented with a pair of claws and pulvili. Tibiae dorsally flattened. Abdomen dark brown, with three pairs (3+3) of white maculae, located between lateral and median plates, which are black. Median dorsal plates black; ostioles on median dorsal plates I-III. Lateral plates semicircular, black, without punctuation, adjacent to lateral margin of each segment. Spiracles near anterior margin of lateral plates, on urosternites II to VIII. From urosternites III to VII, 1+1 trichobothria placed medially of an imaginary line across spiracles and near posterior margin of each segment.

Second instar

(Fig. 21). Body oval and less convex than in first instar. Head less declivent than previous instar, predominantly black, coarsely punctured in the dorsum. Clypeus obtuse at apex, subequal in size to the mandibular plates, which are broader than in previous instar. Eyes almost as wide as base of clypeus. Rostrum black, reaching the metacoxae. Thorax with 1+1 orange maculae along the margins of pronotum; lateral margins of pro- and mesonotum slightly deflected. Legs black, dense hairs on tibiae and tarsus. Abdomen predominantly dark brown, maculae distributed as follows: one pair (1+1) of orange, rounded and large maculae, and two pairs (2+2) of white and rounded maculae. Median and lateral dorsal plates black punctured. Urosternites III to VII with 2+2 trichobothria, one trichobothrium medially of the spiracular line and the other along that line. Other characteristics as described for the first instar.

Third instar

(Fig. 22). Mandibular plates and clypeus subequal in length. Thorax predominantly black, coarsely punctured, with a pair (2+2) of orange maculae along anterolateral margins, which are depressed, slightly deflected and not serrate. Abdomen predominantly black, with maculae distributed as follows: a white small, round macula, anteriad of first median plate; one pair (1+1) of large, orange, semicircular, located between first median and lateral plates; five pairs (5+5) of white and round maculae, located between lateral and median plates; and two pairs (2+2) of white, small maculae located near second and third median plates. All median and lateral plates predominantly black and coarsely punctured; lateral plates semicircular. Other characteristics as described in the previous instars.

Fourth instar

(Fig. 23). Body oval, less convex than in previous instars, predominantly black. Head less declivent than in third instar, clypeus black. Thorax predominantly black, except for shapeless, light orange maculae, on dorsum and margins. Maculae on the dorsum of the thorax light orange. Pronotum trapezoidal; mesonotum rectangular, posterior margin wide, V-shaped, denoting the formation of scutellum. Wing pads slightly developed, reaching posterior margin of metanotum. Lateral plates orange with black margin, with few punctures. Maculae on abdominal dorsum with the same coloration and distribution as in previous instar, but larger. Other characteristics as described in the previous instars.

Fifth instar

(Fig. 24). Body oval to pyriform. Head flat, slightly punctured; mandibular plates wide, each a longitudinal orange band. Thorax predominantly black with a pair (1+1) of orange maculae on pronotum along anterolateral margins and laterally on mesonotum. In some individuals, additional orange maculae are dispersed on the dorsum of the thorax. Pronotum wider, anterolateral margins slightly convex; mesonotum more developed, scutellum well delimited. Wing pads well developed, surpassing the middle of abdominal segment III. Legs black, hairs more abundant ventrally. Abdomen predominantly black, densely dotted, with maculae distributed as follows: one white macula anteriad of the first median plate; one pair (1+1) of orange maculae between lateral and first median plates; four pairs (4+4) white maculae lon segments IV-VII. Lateral plates semicircular, orange with black margins, with few punctures. Median plates predominantly black, coarsely punctured, with orange maculae in the center of the plate. Urosternite VIII split longitudinally in females and entire in males. Other characteristics as described in the previous instars.
