Comefulvius chingonus Carvalho & Carpintero

Comefulvius chingonus Carvalho & Carpintero, 1985: 510 (new species).

Comefulvius chingonus: Carvalho & Froeschner, 1990: 319 (list of Carvalho’s types); Carpintero & Carvalho 1993: 400 (list); Schuh, 1995: 21 (catalog), 2002–2013: (online catalog); Gorczyca, 2006: 27 (catalog).

Redescription. Coloration ( Figs. 1–2 ). Dorsum dark brown to black with developed brown, yellow and dark reddish areas. Head. Mostly dark brown to black; maxillary plate and buccula dark brownish anteriorly, dirty yellowish posteriorly; antenna dark brown; segment I varying from pale to dark brown with a pale brown annulation basally; labial segment I dark brown; segments II–IV dirty yellowish. Thorax. Pronotum. Varying from dark brown to black, except for yellowish humeral angles. Mesoscutum and scutellum. Blackish. Thoracic pleura. Proepisternum and proepimeron blackish; remaining pleura dark brownish. Hemelytron. Basal half fuscous, apical half dark reddish to brownish; corium with relatively large, yellow patch medially, contiguous with inner margin of embolium, corium also with smaller yellowish patch on apex of inner angle; rows of punctures blackish. Legs. Dark brown fuscous with yellowish areas; coxae contrastingly yellow.

Structure, texture, and vestiture. Same as generic description.

Measurements. Male (n=2; based on original Carvalho & Carpintero 1985 measurements and additional measurements of the holotype and the USNM specimen; *: holotype measurements; when measurements of holotype and USNM specimen are identical, value is not repeated). Body. Length: 4.2–4.7*, width 1.5–1.6*. Head. Length: 0.8*–0.9, width: 0.7*–0.8, interocular distance: 0.3. Antenna. Length of segment I: 0.4, II: 0.7*–1.2, III: 0.4*–0.5, IV: 0.4*–0.6. Labium (USNM specimen only, immeasurable in holotype; partially damaged and obscured by glue). Length of segment I: 0.2, II: 3.1, III: 0.2, IV: 0.2. Pronotum. Length: 0.6*–0.7, width of anterior margin: 0.5–0.6*, length of lateral margin: 0.8*, width of posterior margin: 1.3*.

Distribution. Argentina (Córdoba Province), Ecuador (Orellana Province).

Type material. Holotype ♂: Argentina, Cordoba, La Serranita (31º43'58.64''S., 64º27'08.64''O), xi.1981, D. L. Carpintero leg. (transferred from D. L. Carpintero collection to MACN).

Additional examined material. 1 ♂: Ecuador: Orellana Prov. (labeled Napo in error) Tiputini Biodiversity Stn., Tower 1, 0º 37’55” S, 76º08’39 W, 216 m, 3 February 2002, T.J. Henry & P.S.F. Ferreira, ex mercury vapor light ( USNM).

Discussion. The authors were not authorized to dissect the holotype of Comefulvius chingonus to compare its genital structures with those of the USNM specimen. However, the two specimens are very similar by measurements, external morphology and dorsal pattern ( Figs 1–2, 3–4, 6–7 ) and we are confident the minor differences of coloration are only intraspecific variability.

Comefulvius chingonus , previously known from Argentina (Córdoba province), is here mentioned from Ecuador (Orellana province) for the first time. At first glance, it may seem surprising to find a species described from Argentina in Ecuador. However, our knowledge on distribution of the New World cylapine, remains poorly known and the biology of C. chingonus is practically unknown. Similar distribution has been already noted for several New World cylapine. Fulvius bisbistillatus Stål, 1860 , widely distributed from Argentina to Mexico ( Gorczyca 2006; Carpintero & Chérot, under press), is recorded from dry ecosystems such as Chaco National Park in Argentina ( Melo et al. 2011) or Chiquitano forest in Bolivia (Wolski, unpublished) as well as tropical rainforest in Panama ( Carvalho & Costa 1994). Peritropis amphicyrta Wolski & Henry is known from Argentina (Misiones Province) and Ecuador (Orellana Province) ( Wolski & Henry 2012). It is also the case of different mirine and orthotyline such Calocorisca sticticollis (Stål, 1860) , Monalocorisca conspurcata Reuter, 1913 , Taedia incaica Carvalho & Gomes, 1971 (Mirini) , Chiloxionotus nigrofasciatus Reuter, 1907 , Prepops bachmanni Carvalho & Carpintero, 1990 , P. costalis (Stål, 1860) , P. flavoniger tucumanensis (Carvalho & Fontes, 1969) , P. nitidipennis (Reuter, 1910) P. persimilis (Reuter, 1907) (Restheniini) , Adxenetus petiolatus (Stål, 1860) , Lepidoxenetus amyioti (Stal, 1860) , Herdonius armatus Stål, 1860 and H. vittatus Carvalho & Ferreira, 1973 (Herdoniini) or Orthotylus (Melanotrichus) sumalaoensis (Carvalho & Carpintero, 1992) for example ( Carpintero & Carvalho, 1993).
