“…It is possible that the sinuate ovipositor tip in all known species of Promicrogaster is an adaptation allowing the ovipositor to be steered through fissures in harder/more woody structures than mere leaf rolls (e.g., Quicke 2015). Muesebeck (1958) described Promicrogaster polyporicola as reared from unidentified Lepidoptera larvae infesting a bracket fungus (Fomes sp.)…”

“…First, all other Promicrogaster specimens that we have seen in collections (from either described or undescribed species) are restricted to the New World, and all published evidence (e.g., Mason 1981, Whitfield 1997 does not support this genus to be present in India. Second, Promicrogaster saraswatti was described by Sathe and Bhoje (1998) as a parasitoid of Phytomyza atricornis Meigen (Diptera: Agromyzidae), which is very suspicious, as all authenticated records of Microgastrinae are from Lepidoptera (e.g., Shaw and Huddleston 1991, Whitfield 1997, Quicke, 2015. Third, Sathe and Bhoje (1998) recorded in their paper the body size of the parasitoid wasp to be 4.64 mm and the wasp cocoon to be 4.5 mm; this is in strong contrast to a much smaller size for its supposed host: larvae of Phytomyza atricornis are only known to reach a maximum length of 3.5 mm and their puparia are even smaller at 2.1-2.5 mm (Cohen 1936).…”

The genus Promicrogaster (Hymenoptera, Braconidae, Microgastrinae) from Area de Conservación Guanacaste (ACG), Costa Rica, is revised. A key is provided to all new species as well as those previously described from Mesoamerica. A total of 21 species, all authored by Fernandez-Triana & Boudreault, are described as species nova : alexmartinezi, andreyvallejosi, brandondinartei, daniellopezi, daretrizoi, eddycastroi, eimyobandoae, fabiancastroi, fabriciocambroneroi, hillaryvillafuerteae, kevinmartinezi, kiralycastilloae, leilycastilloae, liagrantae, luismendezi, monteverdensis, naomiduarteae, pablouzagai, ronycastilloi, sebastiancambroneroi, tracyvindasae. A species previously described from India is considered as incertae sedis. Promicrogaster is considered to be restricted to the New World, with the vast majority of the species found in the Neotropics and a few extending north to the Nearctic. Almost 60% of the known species in ACG are found in cloud forests at over 1,000 m altitude. All of the verified and authenticated host records for Promicrogaster are from caterpillars living more deeply inside plant tissue than simply in rolled leaf structures -although no host data from ACG is available.

“…In taxonomic studies, most morphological descriptions of Braconidae are concentrated in the adult stage, while the biology and morphology of immature stages still lack information (Quicke 2015).

Morphological characterization of immature stages of Habrobracon hebetor (Hymenoptera, Braconidae) ectoparasitoid of Ephestia kuehniella (Lepidoptera, Pyralidae)

Habrobracon hebetor (Say) is a cosmopolitan idiobiont braconid which parasitizes Pyralidae larvae, a pest of stored products, such as Ephestia kuehniella (Zeller). The objective was to describe the morphology of immature forms of H. hebetor and morphological changes throughout its development. Mated females of H. hebetor were individualized in Petri dishes containing larvae of E. kuehniella for parasitism for six hours. Then, the females were removed, leaving only the eggs placed on the host. The development was evaluated every 12 hours, recording all stages and changes until the emergence of adults. Using stereoscopic optical and scanning electron microscopy, photographs of immature individuals were taken. The results showed that this parasitoid completes its development between 10-12 days. There were stages overlaps during egg to adult development. Eggs are hymenopteriform, with a smooth surface. According to cephalic capsule and larval length measurements of H. hebetor, it was possible to determine four instars. In general, the instars are similar to each other, differing mainly in the size and shape of segments. Larvae present a gradual loss of transparency, becoming opaquer at each successive instar. Last instar larvae distanced from the host to form the cocoon and to pupate. This study was relevant for a better understanding of the physiological interactions between E. kuehniella and H. hebetor.

The pteromalid parasitoid Lariophagus distinguendus (Foerster) belongs to the Hymenoptera, a megadiverse insect order with high cryptic diversity. It attacks stored product pest beetles in human storage facilities. Recently, it has been shown to consist of two separate species. To further study its cryptic diversity, strains were collected to compare their relatedness using barcoding and nuclear genes. Nuclear genes identified two clusters which agree with the known two species, whereas the barcode fragment determined an additional third Clade. Total reproductive isolation (RI) according to the biological species concept (BSC) was investigated in crossing experiments within and between clusters using representative strains. Sexual isolation exists between all studied pairs, increasing from slight to strong with genetic distance. Postzygotic barriers mostly affected hybrid males, pointing to Haldane's rule. Hybrid females were only affected by unidirectional Spiroplasma‐induced cytoplasmic incompatibility and behavioural sterility, each in one specific strain combination. RI was virtually absent between strains separated by up to 2.8% COI difference, but strong or complete in three pairs from one Clade each, separated by at least 7.2%. Apparently, each of these clusters represents one separate species according to the BSC, highlighting cryptic diversity in direct vicinity to humans. In addition, these results challenge the recent ‘turbo‐taxonomy’ practice of using 2% COI differences to delimitate species, especially within parasitic Hymenoptera. The gradual increase in number and strength of reproductive barriers between strains with increasing genetic distance also sheds light on the emergence of barriers during the speciation process in L. distinguendus.
