I made an Index to the Systematic Entomology paper.

New species of Trigonalyidae (Hymenoptera) from NW China.
ZooKeys 698: 17-58 (18 Sep 2017) |
Four new species of Trigonalyidae are described and illustrated from Qinling Mts (Shaanxi, NW China): Bareogonalos xibeidai Tan & van Achterberg, sp. n., Jezonogonalos mandibularis sp. n., J. shaanxiensis sp. n., and Taeniogonalos paraclypeata sp. n. Orthogonalys hirasana Teranishi, 1929, is re-instated and reported from China. The female of Taeniogonalos alticola (Tsuneki, 1991) is described for the first time. In total, 18 species are known from Shaanxi province, 20 species for NW China, and eight described species are newly recorded for Shaanxi: Jezonogonalos luteata Chen et al., 2014, Orthogonalys hirasana Teranishi, 1929, O. elongata Teranishi, 1929, Pseudogonalos hahnii (Spinola, 1840), Taeniogonalos alticola (Tsuneki, 1991), T. formosana (Bischoff, 1913), T. taihorina (Bischoff, 1914), and Teranishia glabrata Chen et al., 2014. Poecilogonalos maga Teranishi, 1929, syn. n. and Taiwanogonalos claripennis Tsuneki, 1991, syn. n. are new synonyms of Taeniogonalos taihorina (Bischoff, 1914) and Taiwanogonalos alishana Tsuneki, 1991, syn. n. of Taeniogonalos alticola (Tsuneki, 1991). Revised keys to species of the genera Bareogonalos, Jezonogonalos, and Orthogonalys are included.

Chinese Trigonalidae are revised, keyed and fully illustrated. Eight genera (Bakeronymus Rohwer, 1922, Bareogonalos Schulz, 1907, Jezonogonalos Tsuneki, 1991, re-instated, Lycogaster Shuckard, 1841, Orthogonalys Schulz, 1905, Pseudogonalos Schulz, 1906, Taeniogonalos Schulz, 1906 and Teranishia Tsuneki, 1991) are recorded from China. The genus Ischnogonalos Schulz, 1907, is synonymized with Taeniogonalos Schulz, 1906. Forty valid species are recognized, 20 are new for science.

Available online: doi: 10.3897/jhr.29.3233
Five species of Trigonalidae, hyperparasitoids of Ichneumonidae (Hymenoptera) and Tachinidae (Diptera) that parasitize caterpillars (Lepidoptera), have been reared during the ongoing caterpillar inventory of Area de Conservación Guanacaste (ACG), Guanacaste Province, northwestern Costa Rica: Lycogaster apicipennis (Cameron), Taeniogonalos woodorum Smith, sp. n., Taeniogonalos fasciatipennis (Cameron), Trigonalys championi Cameron, and Trigonalys maculifrons Sharp. Morphological and DNA barcoding data support species separation of these generalist hyperparasitoids. Taeniogonalos gundlachii (Cresson) is not a widespread, color-variable species as previously treated and is probably confined to eastern North America. The species previously considered as T. gundlachii in Costa Rica is regarded as Taeniogonalos fasciatipennis, a species found only in ACG dry forest. Taeniogonalos woodorum is a similar species but found only in the ACG rain forest. Habitat and host records are given for these five species of trigonalids.
My Comment: Sounds like T. costalis is a valid species for North America, distinct from the Cuban T. gundlachii. If so (and I believe it is based on this paper), I created a mess when I synonymised them!

|Abstract: A survey of Trigonalidae from cacao (Theobroma cacao L.) agroforestry systems in southern Bahia, northeastern Brazil, is conducted. A total of 65 specimens were studied, and three species are recognized. Trigonalys melanoleuca Westwood is diagnosed and illustrated. Two new species are described and illustrated. Trigonalys erythrocephala sp. n. has most of head reddish brown; metasomal armature in sternum III conspicuous, Y-shaped; supra-antennal elevation conspicuous; hind coxa with sharp lateral angles, its dorso-mesal portion strigate; legs entirely dark brown; and fore wing lightly infuscate, darker towards anterior margin. Trigonalys gotica sp. n. with body blackish or dark brown and with pale yellow marks; mesopleuron with an oblique mark; female armature absent; frons and vertex punctate-areolate; supra-antennal elevation subtle; propodeal foramen V-shaped; and fore wing vein M arising distinctly basad to 1cu-a.

"The monophyly of Trigonaloidea is strongly supported, putative autapomorphies being: (1) having a row of small foveolae impressed posteriorly on the mesoscutellum (character 80 : 1); (2) presence of a supramesopleural sclerite (character 101 : 1); (3) presence of an oblique mesopleural ridge (character 114 : 1); (4 + 5) absence of the anterior paracoxal sulcus and presence of the posterior paracoxal sulcus ventrally on the metapleuron (characters 156 : 0; 157 : 1); (6) presence of tarsal plantulae (character 177 : 1; this is a reversal); (7) presence of a cuticular ﬂap lateral to the propodeal spiracle (character 190 : 1)."

Fossil Trigonalidae and Vespidae (Hymenoptera) in Baltic amber
PROCEEDINGS OF THE ENTOMOLOGICAL SOCIETY OF WASHINGTON 107 (1): 55-63 JAN 2005 |
A fossil trigonalid (Trigonalidae: Hymenoptera), Eotrigonalis balticus Poinar, n. gen., n. sp., and a fossil vespid, Palaeovespa socialis Poinar. n. sp., are described from Eocene Baltic amber. Eotrigonalis balticus is a large. robust. heavily armored species, which could have parasitized members of the Vespidae. It can be separated from ail other members of the family by the presence of large scutellar horns. Palaeovespa socialis has the diagnostic characters of members of the subfamily Vespinae and was probably eusocial. It differs from extant vespines by the shape of the clypeus, the presence of interparapsidal furrows and venational characters.

|Guyotemaimetsha enigmatica, a new genus and species of evaniomorphan wasp, is described from the French Albian amber. Its phylogenetic affinities are discussed. It has strong similarities with the genera Maimetsha and Cretogonalys, which are attributed to the Maimetshidae and Trigonalidae, respectively. The exact relationships of these Cretaceous taxa remain enigmatic.|
