Abstract: Burmese amber provides a unique window to the Cretaceous entomofauna, being the most prolific source of fossil insects for the period. Presently, about 61% of the Hymenoptera described from amber deposits in Myanmar are stinging wasps (Aculeata), including eight families known solely from Burmese amber. In the present work we describe the aculeate family †Trifionychidae fam. nov., as well as three new genera: †Prionaspidion gen. nov., including †Prionaspidion brevidens sp. nov. and †P. nanus sp. nov.; †Trifionyx gen. nov., including †Trifionyx pilosus sp. nov.; and †Trifionyximus gen. nov., including †Trifionyximus cracens sp. nov. We also reinterpret the fossil genus †Mirabythus, described based on rock impressions from the Yixian formation in China and originally attributed to Scolebythidae. †Mirabythus is moved to the new family, based mainly on the characteristic mandible; the large clypeus with a series of small denticles on the apical margin; the frons protruding over lateral portions of clypeus, directing the antennal sockets downwards below ocular level; and the presence of nine flagellomeres. Based on resemblances with fossil impressions attributed to †Bethylonymidae, we tentatively include the new family within the superfamily †Bethylonymoidea. Discovery of †Trifionychidae fam. nov. adds a novel lineage to the pool of aculeate families from the Cretaceous which did not survive to the present day.

First records of the genus Gnathochorisis Förster (Hymenoptera, Ichneumonidae, Orthocentrinae) in the Oriental region https://jhr.pensoft.net/article/68700/ Journal of Hymenoptera Research 84: 103-113

DOI: 10.3897/jhr.84.68700

Authors: Andrei E. Humala

Abstract: Oriental members of the genus Gnathochorisis Förster, 1869 (Ichneumonidae: Orthocentrinae) are reviewed, two species: G. leleji sp. nov. from Malaysia and G. malaisei sp. nov. from Myanmar, are described and illustrated. The genus Gnathochorisis is recorded from the Oriental region for the first time.

Studies on the Asian sawflies of Formosempria Takeuchi (Hymenoptera, Tenthredinidae), with notes on the suitability of F. varipes Takeuchi as a biological control agent for skunk vine, Paederia foetida L. (Rubiaceae) in Florida https://jhr.pensoft.net/article/4104/ Journal of Hymenoptera Research 39: 1-15

DOI: 10.3897/JHR.39.8096

Authors: David R. Smith, Paul D. Pratt, Jeff Makinson

Abstract: Formosempria Takeuchi, 1929, is distributed in southeastern Asia from Taiwan and China to Vietnam, Myanmar, and possibly northern India. Three species are included: F. crassicornis Wei & Nie, 2002, F. shanensis Malaise, 1961, and F. varipes Takeuchi, 1929 (= F. annamensis Malaise, 1961, syn. n.; = F. metallica Wei, 2003, syn. n.). Formosempria varipes was reared from larvae feeding on Paederia foetida L. (Rubiaceae) in Hong Kong and was a potential biological agent for the invasive P. foetida in Florida. Larval feeding tests indicate more than one species of Paederia are suitable hosts for F. varipes and further study for use as a biological control agent in Florida is unwarranted. Descriptions and illustration of the species are given, and life history notes on F. varipes are presented.
