ABSTRACT

The braconid wasp Rinamba platyfemur (Marsh) (Hymenoptera: Braconidae) is reported for first time for Mexico;Yucatan Peninsula its northernmost distribution record.

The subfamily Doryctinae is one of the most diverse group of the braconid wasps (Braet et al. 2003), principally in the tropics (Barbalho et al. 1999,Belokobylskij 2004a, Belokobylskij et al. 2011). Some genera are considerably species rich with wide geographical distributions (Nunes et al. 2012). In Mexico a small fraction of total species of Braconidae are known (Figueroa-De la Rosa et al. 2004), until now there are not a deeply systematics revision of Doryctinae, but new species and distribution data are constantly published.

Marsh (1993) established the genus Rhoptocentroides to include R. platyfemur Marsh from Costa Rica, Brazil and Trinidad (Marsh 1993, 2002); posteriorly Belokobylskij (1995) synonymized with Pseudorhoptrocentrus. Finally, Belokobylskij (2004b) established Rhoptrocentroides as a junior synonym of Rinamba, actually the valid genus.

Revision of material deposited in the Colección Entomológica Regional-Universidad Autónoma de Yucatán, Xmatkuil (CER-UADY) reveled the presence of two specimens of Rinamba platyfemur(Marsh), previously unknown for Mexico. Here we detail geographical distribution of this species into Mexico, its northernmost record.

For the identification to subfamily level we used van Achterberg (1990) and Wharton et al. (1997), for species determination the description of Marsh (1993) and the key of Belokobylskij (2004b) were used.

 

Rinamba platyfemur (Marsh)

Material examined. One female. Mexico, Yucatán, El Cuyo, Sacboh, 30/05-17/06/08, Tropical forest, Malaise trap, R. Cauich coll.One female, same data, but 26/06/09.

One specimen deposited in CER-UADY, other in Nationaal Natuurhistorisch Museum, Leiden (RMNH).

Distribution.Costa Rica, Brazil, Trinidad (Marsh, 1993, 2002), and Mexico.

Diagnosis.The scape longer than the first flagellomere, with expanded flange on anterior apical edge is the principal character for correct determination of R. platyfemur; additional characters are propodeum with carina and an apical areola; hind femur, short and broad.

Doryctinae have an incredible diversity at the generic level (Gomes and Penteado-Dias 2007), with high rate of genera and species described worldwide. The Yucatan Pensinsula is potentially rich in braconid wasps, recently 83 species and 29 genera of Agathidinae and Doryctinae were reported from one site intensively collected (Cauich-Kumul et al. 2012).Expand the range of distribution of a Neotropical braconid wasps is not uncommon, description of new taxa and distributional records from the Yucatan Peninsula will be common in the following years.
