ABSTRACT
The genus Leptodrepana Shaw was described in 1983, but prior to the current study only one Neotropical species had been described from Mexico and none were named from Costa Rica. In this paper twenty-four new species are described and named from Costa Rica: L. alexisae Dadelahi & Shaw, sp. n., L. atalanta Dadelahi & Shaw, sp. n., L. conda Dadelahi & Shaw, sp. n., L. conleyae Dadelahi & Shaw, sp. n., L. demeter Dadelahi & Shaw, sp. n., L. eckerti Dadelahi & Shaw, sp. n., L. gauldilox Dadelahi & Shaw, sp. n., L. hansoni Dadelahi & Shaw, sp. n., L. kimbrellae Dadelahi & Shaw, sp. n., L. lorenae Dadelahi & Shaw, sp. n., L. munjuanae Dadelahi & Shaw, sp. n., L. ninae Dadelahi & Shaw, sp. n., L. pamelabbas Dadelahi & Shaw, sp. n., L. ronnae Dadelahi & Shaw, sp. n., L. rosanadana Dadelahi & Shaw, sp. n., L. schuttei Dadelahi & Shaw, sp. n., L. scottshawi Dadelahi, sp. n., L. shriekae Dadelahi & Shaw, sp. n., L. sohailae Dadelahi & Shaw, sp. n., L. sorayae Dadelahi & Shaw, sp. n., L. soussanae Dadelahi & Shaw, sp. n., L. stasia Dadelahi & Shaw, sp. n., L. strategeri Dadelahi & Shaw, sp. n., and L. thema Dadelahi & Shaw, sp. n. A key to Costa Rican species of Leptodrepana is provided. The flagellum of all female Leptodrepana described in this work is reduced to only 17 flagellomeres. This character state is also found in two North American species described by Shaw (1983), L. opuntiae Shaw and L. oriens Shaw. It is hypothesized that a female antenna with 17 flagellomeres is a synapomorphy for a species-group comprising all the Costa Rican Leptodrepana species as well as two of the Mexican and North American species, L. opuntiae and L. oriens.
ABSTRACT
This paper provides the first taxonomic revision for the euphorine genus Centistes from a Neotropical country. Twenty-three new species are described: C. achterbergi sp. n., C. acuticaudatus sp. n., C. auricephalus sp. n., C. auristigma sp. n., C. bicaudatus sp. n., C. cabecares sp. n., C. cartagoensis sp. n., C. chorotegus sp. n., C. compactus sp. n., C. curvicaudatus sp. n., C. gauldi sp. n., C. hansoni sp. n., C. hirsutus sp. n., C. janzeni sp. n., C. laticaudatus sp. n., C. longicaudatus sp. n., C. marshi sp. n., C. muertensis sp. n., C. ornamentum sp. n., C. pilosus sp. n., C. puntarenensis sp. n., C. sergeyi sp. n., C. zurquiensis sp. n. A taxonomic key, including the two previously described species, C. epicaeri Muesebeck and C. gasseni Shaw, is presented. As a whole, the Centistes exhibit their highest diversity in the premontane cloud forests.

A comprehensive key for 75 species of Meteorus distributed across 15 Neotropical countries is presented. Eleven new species from Bolivia, Costa Rica and Ecuador are described: Meteorusalbistigma, Meteoruscarolae, Meteoruseurysaccavorus, Meteorusfallacavus, Meteorusflavistigma, Meteorushaimowitzi, Meteorusmagnoculus, Meteorusmartinezi, Meteorusmicrocavus, Meteorusnoctuivorus and Meteorusorion. Expanded range distributions are recorded for Meteorusandreae, Meteorusfarallonensis, Meteorusguineverae, Meteorusjerodi, Meteoruskraussi, Meteoruspapiliovorus and Meteorusquimbayensis. The host of Meteorusjerodi is reported for the first time: a noctuid larva feeding on Asteraceae. Meteoruspapiliovorus is recorded attacking Papilionidae larvae in Ecuador, therefore displaying a similar host family preference as formerly documented from Costa Rica and Colombia.
ABSTRACT
Three new species of Meteorus parasitoids of Arctiinae are described: Meteorus anuae n. sp., M. juliae n. sp. and M. mirandae n. sp. The first biological record for M. cecavorum Aguirre & Shaw as well as its cocoon description is reported. A comprehensive key for the Neotropical Meteorus attacking Arctiinae is provided. A total of nine Meteorus species have been reared from Arctiinae in the Neotropical Region. Six of them are gregarious and three solitary. The biological information about host and food plants concurs with the hypothesis of specialist parasitoids preferring "nasty" caterpillars.
