Hymenoptera, Stephanidae, Megischus brunneus, Hispaniola, primer registro.IntroductionThe only moderately diverse family Stephanidae (Hymenoptera) contains species of solitary idiobiontectoparasitoids of wood boring insect larvae (332 species worldwide; see Aguiar and Johnson 2003; Aguiar2006a, b, c). Stephanid wasps are remarkable insects, with a slender and richly sculptured body, highlymodified hind legs, and a somewhat spherical head - set out on a long neck - which bears a crown oftubercles around the median ocellum (Aguiar 2006a, b).Megischus Brullé is a cosmopolitan genus (Aguiar 2004; Hong et al. 2011). Aguiar and Johnson(2003) provided data on geographical distribution, biology and a key to the North American species ofMegischus, including the Antilles.  Aguiar (2006c) subsequently also revised the Mexican species. Aguiar(2006c) revised the Mexican species, describing new ones and offering a key.Megischus brunneus Cresson can be recognize by having a pronotum with four sharp transversecarinae, and mesopleuron and prosternum with dense foveolae, each separated by less than their diam-eter (Aguiar and Johnson 2003). The species was previously known from the United States (SouthernFlorida) and Cuba (Townes 1949; Alayo 1972, 1973; Aguiar and Johnson 2003; Aguiar 2004). This studyprovides the first record of the occurrence of M. brunneus for Hispaniola, the Antilles.Codens for collections mentioned here are as follows: Department of Biology, University of PuertoRico at Mayagüez (UPRM) (located in Mayagüez); personal collection of the author (JAGA).ResultsIn November of 2003 evidence was gathered on the occurrence of this species in the DominicanRepublic. This was possible because of a direct sighting and capture of a single female in the town ofOviedo, Pedernales, in the backyard of the Jaragua Group facilities. Unfortunately the material wassubsequently stolen. Nevertheless, further collecting in Jaragua yielded another female and anotherfemale was found in the UPRM collection, which validates this new record.The specimen collected at Oviedo lake was resting on a mangrove’s trunk (Fig. 1). The habitat (Fig.2) is characterized by the following mangrove species: Rhizophora mangle (L.) Rhizophoraceae, Avicenniagerminans (L.) L. Avicenniaceae, Conocarpus erectus L. Combretaceae and Laguncularia racemosa (L.)Gaertn. f. Combretaceae. Similar habitats have been reported elsewhere for this species (Aguiar and2 • INSECTA MUNDI 0216, March 2012 GENAROJohnson 2003). The distributional records (Fig. 3) show that M. brunneus is present in dry areas of thesouthwestern Dominican Republic.Material examined.

Portions of Cuba and Hispaniolawere connected during Latest Eocene-Early Oligocene (35-33 Ma), a time of general uplift and a maxi-mum area of subaerial land (Iturralde-Vinent 2006). This offered favorable conditions for sharing biota.After the Late Oligocene (29-27 Ma) isolation of land areas resulting in the subdivision and separation ofblock-terraces previously acting as continuous landmasses (Iturralde-Vinent 2006). Perhaps vicariancehas isolated populations of M. brunneus creating the present-day distribution patterns.AcknowledgmentsI am grateful to Victor González who encouraged the study of insects and generously provided logis-tic support for field trips during several years. I thank the personnel of Jaragua group for logisticalsupport of expeditions and especially Ivonne Arias and Héctor Andujar also for facilitation of collectingpermits and use of Jaragua National Park infrastructure. I thank to my colleagues G. Alayón, E. Gutiérrezand A. Peréz-Asso for collaboration during several years of expeditions. Thanks to Nico Franz for facili-tating the access to the UPRM insect collection to study the specimen. Cooperation of Secretaría deEstado de Medio Ambiente y Recursos Naturales for obtaining field work permits is greatly appreciated.Fabiola Areces (University of Puerto Rico at Río Piedras) provided identifications and information aboutvegetation. Carlos Suriel and Celeste Mir (Museo Nacional de Historia Natural de Santo Domingo)always supported with pleasure our research in the island and permitted the use of museum installa-tions. I extend special thanks to James Carpenter, Nico Franz and José L. Fernández for reviewing themanuscript and offering valuable suggestions.Figures 1-2.
