Abstract: A new fossil species of Dryinidae (Hymenoptera, Chrysidoidea) from upper Eocene Rovno amber (Ukraine) is described: Bocchus rex sp. nov. It is compared with two other species of Bocchus known from European amber: B. primaevus Martins & Melo from Baltic amber and B. schmalhauseni Perkovsky, Olmi, Vasilenko, Capradossi & Guglielmino from Rovno amber. A new key to the Cretaceous and Paleogene species of Bocchus is presented. The Dryininae are the most common representatives in all the amber dryinid faunas since the mid-Cretaceous. The Rovno amber fauna is an exception; possible explanations for the abundance of Bocchus species within this amber are presented.

New species of Hybristodryinus Engel (Hymenoptera, Dryinidae) from mid-Cretaceous amber of northern Myanmar, with notes on their possible hosts https://jhr.pensoft.net/article/57792/ Journal of Hymenoptera Research 81: 43-55

DOI: 10.3897/jhr.81.57792

Authors: Massimo Olmi, Hua-Yan Chen, Chungkun Shih, Patrick Müller, Leonardo Capradossi, Dong Ren, Evgeny E. Perkovsky, Adalgisa Guglielmino

Abstract: Two new species of Hybristodryinus Engel, 2005, are described from mid-Cretaceous amber of northern Myanmar: H. castaneus sp. nov. (based on one male) and H. zaifui sp. nov. (based on one female). Keys to the females and males of Hybristodryinus species are modified to include the two new taxa. A syninclusion, a nymph of Cixitettiginae (Perforissidae), present in the same amber piece containing H. zaifui, is studied. This syninclusion, together with the presence of Antennal Dorsal Organs (ADOs) in Hybristodryinus, suggests that Perforissidae are possible hosts of Hybristodryinus.

Revision of the fossil species of Thaumatodryinus Perkins from Dominican amber, with a new combination and description of a new species (Hymenoptera, Dryinidae) https://jhr.pensoft.net/article/57686/ Journal of Hymenoptera Research 79: 77-88

DOI: 10.3897/jhr.79.57686

Authors: André L. Martins, Gabriel A. R. Melo

Abstract: The fossil species of Thaumatodryinus from Dominican amber are studied, and the first revision is presented with a key to the known taxa. We recognize three species, T. miocenicus Olmi, 1995, T. priscus (Olmi, 1998), comb. nov. and T. fuscescens sp. nov. The current classification of the genus and relationships between fossil and living species are discussed. Comments on the host records for Thaumatodryinus are presented.

Description of Aphelopus fuscoflavus, a new species of Dryinidae from Thailand (Hymenoptera, Chrysidoidea) https://jhr.pensoft.net/article/12462/ Journal of Hymenoptera Research 57: 115-121

DOI: 10.3897/jhr.57.12462

Authors: Adalgisa Guglielmino, Massimo Olmi, Alessandro Marletta, Zai-fu Xu

Abstract: A new species of Aphelopus Dalman is described from Thailand, Sakon Nakhon: A. fuscoflavus sp. n. Morphologically the new species is similar to A. zonalis Xu, Olmi & He, 2013, known from China, Hainan, but it is clearly different in having the basivolsella fused with the paramere, while the basivolsella is not fused with the paramere in A. zonalis. Published identification keys to the Oriental species of Aphelopus are modified to include the new species.

First record of the parasitoid Gonatopus flavipes Olmi, 1984 (Hymenoptera, Dryinidae) in Brazil’s Amazon forest https://jhr.pensoft.net/article/8897/ Journal of Hymenoptera Research 50: 191-196

DOI: 10.3897/JHR.50.8897

Authors: André Luis Martins, Diones Krinski

Abstract: This study reports for the first time the occurrence of Gonatopus flavipes Olmi, 1984 in Pará State, Brazil. Specimes were collected on upland rice crops of Cambará variety in Novo Progresso (7°07'45.71"S 55°23'21.13"W). A sampling of insects with pitfall traps was conducted between November 2010 and March 2011. Specimens of G. flavipes were identified, illustrated and deposited in the Entomological Collection of the Department of Zoology, Federal University of Paraná, Curitiba, Brazil (DZUP/UFPR). This record indicates that rice crops may represent important habitats for this species.

Phylogenetic relationships among the subfamilies of Dryinidae (Hymenoptera, Chrysidoidea) as reconstructed by molecular sequencing https://jhr.pensoft.net/article/5010/ Journal of Hymenoptera Research 45: 15-29

DOI: 10.3897/JHR.45.5010

Authors: Carly Tribull

Abstract: Previously, the only published phylogenetic analysis of Dryinidae was a morphological analysis of just 32 characters. Herein, I present the first analysis of molecular sequence data examining the relationships among several of the major subfamilies of Dryinidae. A total of 77 specimens of Dryinidae from seven subfamilies, two specimens of Chrysis (Chrysididae), one specimen of Cleptes (Chrysididae), and one specimen of Sclerogibba (Sclerogibbidae) were examined utilizing molecular sequence data from nuclear 18S and 28S genes and mitochondrial Cytochrome Oxidase Subunit I (COI) and Cytochrome b (Cytb) genes. Dryininae were rendered nonmonophyletic due to the placement of Thaumatodryinus, which was sister to the remainder of Dryininae and Gonatopodinae. To establish monophyly of Dryininae, Thaumatodryininae were resurrected for Thaumatodryinus.
