REVSYS: SYSTEMATICS OF THE
SCORPION FAMILY VAEJOVIDAE

Southern México (Chiapas): 2.5 weeks (21 May–7 June, 2005), mostly funded by the Instituto de Ecología and the Instituto de Biología, UNAM, augmented with funds from the REVSYS Vaejovidae grant.  REVSYS Collaborator Dr Oscar Francke undertook a three-part trip during these dates.  The first week, Francke was accompanied by three undergraduate students, Milagros Córdova and Abigail Jaimes (both from Universidad Autónoma de Morelos), and Jesús Ballesteros (Instituto Politecnico Nacional), spending several days at the El Ocote Biosphere Reserve collecting arachnids, and in particular a new Vaejovis, a rare Diplocentrus and some Centruroides species.  The second part of the trip included other graduate and undergraduate students in arachnology involved in the Lacandona Forest survey, who met in Tapachula to attend the Mexican Entomological Society Congress, and presented papers and posters on the results obtained thus far.  The final part of the trip returned to the Lacandona Forest to continue collecting arachnids and service pit fall traps set on the previous trip.  Griselda Montiel Parra (Technician, National Acarology Collection), Gabriel Villegas (Ph.D. student, IBUNAM), and Susana Rubio (undergraduate student, Instituto Politécnico Nacional) accompanied Dr. Francke on this trip, and collected numerous arachnids including four different species of scorpion.
