………………….. …………………………….Apanteles juanapui Fern dez-Triana, sp. n. (N=1)?javierobandoi BMS-5 biological activity species-group This BMS-5 web comprises two species, characterized by glossa elongate (Figs 130 e, 131 e), tegula and humeral complex of same color (dark brown), and ovipositor about the same width from base to apex. Although the molecular data does not support the grouping of these species, and host information is only available for one of them, we have decided to consider them as a group because the combination of morphological characters detailed above is unique among Mesoamerican Apanteles. However, this group should be considered as preliminary and further study may change its status in the future. Hosts: Choreutidae. All described species are from ACG. Key to species of the javierobandoi group 1 Antenna shorter than body, at most extending to half of metasoma; body length and fore wing length 2.4 mm; T1 length 2.4 ?its width at posterior margin; T2 mostly sculptured …………………………………………………………….. ……………………………Apanteles juangazoi Fern dez-Triana, sp. n.

(N=4)?Review of Apanteles sensu stricto (Hymenoptera, Braconidae, Microgastrinae)…joserasi species-group This group comprises one described species, although we have seen another undescribed species from the same area (with the interim name Apanteles Rodriguez79) which is only known from a male in poor condition and cannot be described in this paper. It is characterized by glossa elongate; ovipositor relatively thick and strong (with basal width more than 3.0 ?its apical width posterior to constriction); maximum height of mesoscutellum lunules 0.7 ?maximum height of lateral face of mesoscutellum; and propodeum with strong sculpture limited to anterior half, with posterior half mostly smooth and shiny, and with transverse carinae complete and strongly raised. All morphological traits mentioned above are similar to the leucostigmus species-group, and it might be that in the future this group is sunk within the much larger and widespread leucostigmus. However, molecular data (Fig. 1) as well as biological data (species are solitary and parasitize Venada in the joserasi group, whereas all known species in the leucostigmus group are gregarious and parasitize many genera of Eudaminae but not Venada) suggest that joserasi is better considered as a disctinct group for the time being. Hosts: Hesperiidae. The described species is from ACG.keineraragoni species-group This group includes two species, characterized by ovipositor sheaths half the length of metatibia, relatively short inner metatibial spur (at most 0.4 ?as long as first segment of metatarsus), and body extensively dark brown to black (including full meso- and metasoma, and all coxae). All other known species of Mesoamerican Apanteles with relatively short ovipositor sheats (i.e., 0.6 ?or shorter than metatibia) have a rather extensive yellow-orange coloration. The molecular data does not support this group (Fig. 1), nor does it biology (one species is solitary on crambids, and the other is gregarious on riodinids), but we have decided to keep i…………………… …………………………….Apanteles juanapui Fern dez-Triana, sp. n.
