Telebasis rojinegra sp. nov. was recorded from ponds at La Selva Biological Station and three other sites in the Caribbean lowlands of Costa Rica. The new species appears closely related to T. boomsmae Garrison, 1994 recorded from Mexico, Belize and Costa Rica, T. collopistes Calvert, 1902 ranging from Mexico to Honduras, and T. garrisoni Bick & Bick, 1995 from South America, but differs in having straighter and more elongate paraprocts and a half black pattern on the rear of the head. The female mesostigmal plates are also distinct from the above species. Telebasis rojinegra was active on the water primarily during afternoon hours.

Many conservation organizations have attempted to reduce local threats to protected areas (PAs) by providing environmental education programmes in neighbouring communities. There is a great need to understand the effectiveness of these programmes in promoting support for PAs and ultimately reducing threats to biodiversity. La Selva Biological Station, a private PA in Costa Rica, has become increasingly threatened by illegal hunting in the PA and deforestation and land degradation in surrounding areas. The Station has responded with several outreach projects including an annual free visiting day. This study used a survey instrument to evaluate the benefits of local residents visiting La Selva. Specifically, three questions were asked: (1) is there a difference in ecological knowledge of local residents among residents who have visited the Station and those that have not; (2) does an increase in knowledge relate to a perceived benefit from the PA; and (3) does recognition of a perceived benefit among local people result in fewer residents admitting to hunting or desiring to hunt in the PA? This study showed that those residents who had visited the station had a greater understanding of ecological concepts than those residents that had never been to the station, suggesting that such visits provided educational opportunities. Men also had greater ecological knowledge than women. Additionally, residents were more likely to value the PA if they had a greater knowledge of local ecology and conservation. Increased knowledge and recognition of perceived benefit however, do not necessarily translate into lifestyle changes that benefit conservation; no relationship was detected between residents who stated they benefited from the PA and those who said they did not have a desire to hunt, but younger respondents were more likely to express an interest in hunting than older respondents. The results presented here suggest that protected areas generally may benefit from visitation by local residents. However, further study is needed to determine if such outreach activities actually decrease local threats to conservation efforts, such as hunting.

Colony Survival

In the Epiponini, queen number declines through colony cycle, becausesome queens are expelled from colonies. Here we demonstratethat Epiponini wasps may accept expelled queens in situations ofqueenlessness. One colony of Protopolybia exigua was observed at theUniversity of São Paulo in Brazil; and another of Metapolybia docilis wasobserved at La Selva Biological Station in Costa Rica. Queen removaltests were performed to study workers’ acceptance of expelled queensand queens from other colonies. In P. exigua, the experimental queenelimination caused a change in the workers’ behavior, ranging fromaggressive expulsion of non-selected queens to re-acceptance. In M.docilis workers were willing to accept queens from other colonies afterqueen elimination. Our results indicate that because of a decrease inworkers aggressiveness during the colony cycle, workers may acceptexpelled queens (even foreign ones, in experimental situations) in orderto ensure colony survival.
