Uma nova espécie de Tanycarpa Förster (1862) (Hymenoptera: Braconidae: Alysiinae) do Parque Nacional do Itatiaia, Rio de Janeiro, Brasil

Abstract

This is the first description of a species of the genus Tanycarpa Förster (1862) for Brazil. Forty-eight specimens were collected in High Montane Dense Ombrophilous Forest area at National Park of Itatiaia, RJ, using four Malaise traps installed, respectively, at four different altitudes. This study is based on a description of two species of Tanycarpa from Colombia, Tanycarpa edithae and Tanycarpa sarmientoi, which are the only species of this genus recognized for the neotropics.

1 Introduction

The Braconidae are the second largest family of Hymenoptera, within the superfamily Ichneumonoidea, with approximately 19,439 described species included in 46 recognized subfamilies (Yu et al., 2012Yu, D.S., Achterberg, C.V. and Horstmann, K., 2012. World Ichneumonoidea 2011: taxonomy, biology, morphology and distribution. Vancouver: Taxapad. CD version.); among these subfamilies, the Alysiinae are an easily distinguishable group by having exodont mandibles (Dix-Luna, 2009Dix-Luna, O.J., 2009. Sinopsis de las especies de la subfamilia Alysiinae (Hymenoptera: Braconidae) em Colombia. Bogotá: Science College, Department of Biology, Universidad Nacional de Colombia, 248 p. Masters Dissertation.).

Alysiinae are a cosmopolitan subfamily, with more than 2,300 worldwide described species grouped in 104 genera (Yu et al., 2012Yu, D.S., Achterberg, C.V. and Horstmann, K., 2012. World Ichneumonoidea 2011: taxonomy, biology, morphology and distribution. Vancouver: Taxapad. CD version.), of which 41 were recorded in the New World (Wharton, 1994Wharton, R.A., 1994. New genera, species, and records of New World Alysiinae (Hymenoptera: Braconidae). Proceedings of the Entomological Society of Washington, vol. 96, pp. 630-664.). The group is divided into two tribes, Dacnusini and Alysiini, which are separated by the absence (Dacnusini) or presence (Alysiini) of r-m vein in the forewing (Wharton, 1980Wharton, R.A., 1980. Review of the Nearctic Alysiini (Hymenoptera: Braconidae) with discussion of generic relationships within the Tribe. 104 p. Berkeley: University of California Press. University of California Publications in Entomology, no. 88.); both have approximately the same number of species, however Alysiini contains 31 of the 41 genera occurring in the New World (Wharton, 1994Wharton, R.A., 1994. New genera, species, and records of New World Alysiinae (Hymenoptera: Braconidae). Proceedings of the Entomological Society of Washington, vol. 96, pp. 630-664.).

All Alysiinae are endoparasitoids cenobionts of ciclorraphous dipterous larvae (Griffiths, 1964GRIFFITHS, G.C.D., 1964. The Alysiinae (Hymenoptera: Braconidae) parasites of Agromyzidae (Diptera). I. General questions of taxonomy, biology and evolution. Beiträge zur Entomologie, vol. 14, pp. 823-914.; Wharton, 1997Wharton, R.A., 1997. Alysiinae. In: R.A. WHARTON, P.M. MARSH and M.J. SHARKEY, eds. Manual of the New World Genera of the Family Braconidae (Hymenoptera). Washington: International Society of Hymenopterists, pp. 85-118.) and have as hosts specially species of Phoridae, Drosophilidae and Tephritidae (Ovruski et al., 2000Ovruski, S., Aluja, M., Sivinski, J. and Wharton, R., 2000. Hymenopteran parasitoids on fruit-infesting Tephritidae (Diptera) in Latin America and the southern United States: diversity, distribution, taxonomic status and their use in fruit fly biological control Integrated Pest. Management Review, vol. 5, pp. 81-107.), Agromyzidae, Calliphoridae, Chloropidae, Muscidae and Ephydridae (Dix-Luna, 2009Dix-Luna, O.J., 2009. Sinopsis de las especies de la subfamilia Alysiinae (Hymenoptera: Braconidae) em Colombia. Bogotá: Science College, Department of Biology, Universidad Nacional de Colombia, 248 p. Masters Dissertation.). The ciclorraphous flies can cause damage to certain crops; therefore the Alysiinae have been increasingly used in the biological control of pests in crops (Hendrikse et al., 1980Hendrikse, A., Zucchi, R., LENTEREN, J.C.V. and WOETS, J., 1980. Dacnusa sibirica Telenga y Opius pallipes Wesmael (Hym., Braconidae) in the control of the tomato leafminer Liriomyza bryoniae Kalt. Zurich: IOBC-WPRS, pp. 83-98. Bulletin IOBC/WPRS, no. 3.), thus it is necessary to contribute to the knowledge of taxonomy and biology of this subfamily.

According to Dix-Luna (2009)Dix-Luna, O.J., 2009. Sinopsis de las especies de la subfamilia Alysiinae (Hymenoptera: Braconidae) em Colombia. Bogotá: Science College, Department of Biology, Universidad Nacional de Colombia, 248 p. Masters Dissertation., the Alysiinae are still poorly studied in the Neotropical region. In Brazil, Arouca and Penteado-Dias (2004)Arouca, R.G. and Penteado-Dias, A.M., 2004. First record of Foerster (Hymenoptera: Braconidae: Alysiinae) from Brazilian Atlantic Forest. PhaenocarpaEntomotropica, vol. 19, no. 3, pp. 44-46. and Arouca et al. (2004)AROUCA, R.G., PENTEADO-DIAS, A.M. and ACHTERBERG, C.V., 2004. A new species of Foerster (Hymenoptera: Braconidae: Alysiinae) from Brazil. PhaenocarpaZoologische Medelingen Leiden, vol. 78, no. 5, pp. 123-130. reported the occurrence of several genera that already had been described occurring in other New World places as well as undescribed species (Arouca, 2005Arouca, R.G., 2005. Taxonomia e diversidade dos Alysiinae (Hymenoptera: Braconidae) Neotropicais, com ênfase na fauna da Mata Atlântica, Brasil. São Carlos: Universidade Federal de São Carlos, 111 p. Masters Dissertation.).

Tanycarpa Förster (1862) belongs to Alysiini tribe; it is a cosmopolitan group, where the major number of species (11 species) is found in East Palaearctic (Yu et al., 2012Yu, D.S., Achterberg, C.V. and Horstmann, K., 2012. World Ichneumonoidea 2011: taxonomy, biology, morphology and distribution. Vancouver: Taxapad. CD version.). It has 20 recognized species worldwide, of which four are distributed in Nearctic and only two occur in the Neotropics (Yu et al., 2012Yu, D.S., Achterberg, C.V. and Horstmann, K., 2012. World Ichneumonoidea 2011: taxonomy, biology, morphology and distribution. Vancouver: Taxapad. CD version.). Their hosts are ciclorraphous Diptera of the genus Drosophila, Mycetophila, Liriomyza and Scaptomyza (Yu et al., 2012Yu, D.S., Achterberg, C.V. and Horstmann, K., 2012. World Ichneumonoidea 2011: taxonomy, biology, morphology and distribution. Vancouver: Taxapad. CD version.).

Dix (2010)Dix, O., 2010. Cuatro especies nuevas de Alysiinae (Hymenoptera: Braconidae) y registro nuevo para Colombia. Revista Colombiana de Entomologia, vol. 36, no. 2, pp. 304-314. described the only two recognized species in the Neotropical Region, both from Colombia: Tanycarpa sarmientoi, collected between 2,100 and 2,905 meters of altitude, and Tanycarpa edithae, collected between 650 and 2,220 meters of altitude.

Wharton (1980Wharton, R.A., 1980. Review of the Nearctic Alysiini (Hymenoptera: Braconidae) with discussion of generic relationships within the Tribe. 104 p. Berkeley: University of California Press. University of California Publications in Entomology, no. 88., 1997Wharton, R.A., 1997. Alysiinae. In: R.A. WHARTON, P.M. MARSH and M.J. SHARKEY, eds. Manual of the New World Genera of the Family Braconidae (Hymenoptera). Washington: International Society of Hymenopterists, pp. 85-118.) cited the occurrence of this genus in Brazil, but did not elaborate any description related to this record; therefore, this paper presents the first description of a new species of Tanycarpa from Brazil and aims to contribute to the knowledge of the Brazilian fauna of Alysiinae.

2 Material and Methods

The material was collected at Itatiaia National Park (S 22° 30’ and 22° 33’; W 42° 15’ and 42° 19’), a protected area of natural ecosystems situated within the Massif of Itatiaia, Serra da Mantiqueira; it is located between the States of Rio de Janeiro and Minas Gerais, comprising the following cities: Resende and Itatiaia, in Rio de Janeiro State, and Itamonte and Bocaina de Minas, in Minas Gerais State.

Samples were collected with the trap model proposed by Townes (1972)Townes, H.A., 1972. A light-weight Malaise trap. Entomological News, vol. 83, pp. 239-247. model and installed at different altitudes: 987 meters (S 22° 26’ 16.8” W 44° 36’ 41.8”), 1,763 meters (S 22° 22’ 22.5” W 44° 45’ 19.7”), 2,176 meters (S 22° 21’ 50.6” W 44° 44’ 38.4”) and 2,206 meters (S 22° 21’ 36.9” W 44° 43’ 56”); the Malaise at 987 meters of altitude is located in the city of Itatiaia, Rio de Janeiro State, and the traps installed above 1,000 meters of altitude are located in the city of Itamonte, Minas Gerais State. Samples were collected from July 2011 to June 2012, and at each altitude were obtained one sample per month.

In areas with altitude from 1,100 to 2,200 meters to North, the predominant type of vegetation is the Dense Ombrophilous High-Montane Forest (Santos, 1998Santos, R.F., 1998. Mapeamentos temáticos do Parque Nacional do Itatiaia. Brasília: IBAMA/FBDS, pp. 40-48.), a variation of formation of the Atlantic Forest. The climate in the high mountain areas above 1,600 meters, according to Köppen standards is Cwb (mesothermal, with mild summer and rainy season in summer); the cold and dry period corresponds to months between May and August, with very common intense frosts and high rate of insolation and evaporation. Annual rainfall is about 2,400 mm, and January has the greater intensity; the absolute maximum humidity occurs in December, with 83%, and the minimum is in June, with 62% (Santos, 1998Santos, R.F., 1998. Mapeamentos temáticos do Parque Nacional do Itatiaia. Brasília: IBAMA/FBDS, pp. 40-48.).

All the material were preserved in absolute alcohol (100%); subsequently, the specimens were dried and mounted on entomological pins to be identified on genus level, based on Wharton (1997)Wharton, R.A., 1997. Alysiinae. In: R.A. WHARTON, P.M. MARSH and M.J. SHARKEY, eds. Manual of the New World Genera of the Family Braconidae (Hymenoptera). Washington: International Society of Hymenopterists, pp. 85-118.. The studied material is deposited in the Collection of the Department of Ecology and Evolutionary Biology at the Federal University of São Carlos (DCBU), SP, Brazil.

The description of this new species followed Dix (2010)Dix, O., 2010. Cuatro especies nuevas de Alysiinae (Hymenoptera: Braconidae) y registro nuevo para Colombia. Revista Colombiana de Entomologia, vol. 36, no. 2, pp. 304-314.; the nomenclature of sculpture followed Harris (1979)Harris, R.A., 1979. A glossary of surface sculpturing. Occasional Papers in Entomology, vol. 28, pp. 1-31.; the nomenclature of the veins and of the body morphology followed Sharkey and Wharton (1997)Sharkey, M.J. and Wharton, R.A., 1997. Morphology and terminology. In: R.A. WHARTON, P.M. MARSH and M.J. SHARKEY, eds. Manual of the New World Genera of the Family Braconidae (Hymenoptera). Washington: International Society of Hymenopterists, pp. 85-118.; the measures of the specimens followed Goulet and Mason (2006)Goulet, H. and Mason, P.G., 2006. Review of the Nearctic species of Leiphron and Peristenus (Hymenoptera: Braconidae: Euphorinae) parasitizing (Hemiptera: Miridae: Mirini). LygusZootaxa, vol. 1323, pp. 1-118..

The images were obtained in a scanning electron microscope FEI Quanta 250 in low vacuum with uncoated material, and with a digital camera Leica DFC295 attached to a stereomicroscope Leica M205_C using auto-montage software Leica Application Suite.

Similar to T. sarmientoi (Dix, 2010Dix, O., 2010. Cuatro especies nuevas de Alysiinae (Hymenoptera: Braconidae) y registro nuevo para Colombia. Revista Colombiana de Entomologia, vol. 36, no. 2, pp. 304-314.) by the proportion width/length of the face, the densely setose median area and laterally with dispersed setae, the hind wing m-cu vein is weakly impressed and the proportion of the ovipositor/mesosoma length. It differs from both species by having disperse setae on scutellum and the dark yellow color of clypeus (in T. edithae and T. sarmientoi the scutellum is densely setose and the clypeus is brown).
