3DD4137E3EEE749861D58DC0C7326D1A.taxon	discussion	While there have been at least 37 male specimens collected in Europe (Fig. 32), we were unable to associate any of them with the females of any of the four described European species (P. albina, P. pilosator, P. lucida, and P. punctulata). This difficulty appears to result from two factors: strong sexual dimorphism between males and females and the morphological similarity among male specimens. Sexual dimorphism complicates these associations. Piogaster males and females of the same species vary in colour and sculpture (see P. daisetsuzana female and male specimens in Figs 7, 8, 9, 10), with males tending have darker bodies and legs lacking the stripes that are typical of females, as one example. A similar pattern appears to occur in European species. Although at least 31 female P. pilosator are known from collections, and additional photos of female specimens exist online, to our knowledge there are no male specimens that have similar morphology to these females. In addition to sexual dimorphism, European males appear to be morphologically cryptic. Male Piogaster have been collected from a wide geographic distribution in Europe (Fig. 32), yet we found very little morphological variation between these specimens. The few characters that do vary (e. g., colour of the face and coxae, strength of metasomal grooves, and presence of a short epomia) may represent intraspecific variation rather than species-level differences. In addition, much of the variation that exists between male specimens is likely not species level variation, as highlighted in the comments detailing variation between six males collected at the same locality in Italy on 25 – 28 May 1990. Consequently, we were unable to identify diagnostic characters that would allow reliable differentiation of European males or their association with known females. Molecular data have so far not resolved these associations. Two European male specimens have been DNA barcoded (Figs 1, 2, Suppl. material 2), but neither could be confidently linked to females. One specimen collected in Norway showed unstable (rogue-like) placement in both COI phylogenies (Figs 1, 2) with low bootstrap support and did not cluster within a species clade in either case. A portion of this specimens COI sequence was removed prior to phylogenetic analysis due to frame shift mutations in the alignment. Chromatograms were not available, but the unstable placement of this specimen may reflect lower-quality sequencing or base-calling errors. Another specimen collected in Germany clustered within the P. albina + P. pilosator mixed clade, but morphological examination could not link it definitively to either species. We examined 16 European male specimens, and the description of those specimens is included below. This description is provided to detail the similarity of these male specimens, highlight the differences between males and females, and provide characters to distinguish these males from the Nearctic male specimen and the two P. daisetsuzana males.	en	Bass, Amber, Bennett, Andrew M.

3DD4137E3EEE749861D58DC0C7326D1A.taxon	discussion	Comments. The male Piogaster from Italy represent the first record of the genus for Italy. Fourteen male specimens were collected at the same locality between May 25 and 31, 1990, and therefore likely represent the same species. However, the six specimens of these fourteen examined as part of this study vary in the colour of the clypeus, malar space, and face (compare Fig. 24 C with uniform colour to Fig. 24 D with the maximal yellow markings found in these specimens), colour of the fore and middle coxae (primarily yellow-white versus entirely medium brown), strength of metasomal grooves (weak versus strong on T 2 and T 3), and presence or absence of a short epomia. If these specimens are conspecific, this indicates that the variable characters listed above are not reliable for diagnosing species based on males. We attempted to sequence the COI barcoding region of three of these specimens but were unsuccessful. Two historical male-female associations have been suggested based on collection data but lack morphological support. First, Perkins (1958) described a male as possibly being P. punctulata based on superficial resemblance to the female. Male Piogaster specimens are commonly identified as P. punctulata as they are most similar morphologically to the female holotype of P. punctulata (Figs 16, 17), particularly the polished, sparsely punctate mesopleuron. We were unable to locate this male to examine it as part of this study. Second, Aubert (1963) described a male Piogaster from southern France (Fos-sur-Mer) as P. albina based on its collection alongside multiple females of that species (Aubert 1965). Our examination found no morphological evidence supporting (or refuting) this identification and P. pilosator has also been collected in close proximity (Fig. 30), including a syntype collected at Èze (Aubert 1958) and three specimens collected in St. Tropez (Suppl. material 1: Specimen data). This specimen is old and would be unlikely to result in an extraction with a high enough concentration to successfully amplify the COI barcoding gene using a standard PCR protocol, so we did not attempt this. In addition to these historical published associations, we examined two male specimens collected in Lot-et-Garrone, France (May 27 – 31, 1991) that were likely associated with a female P. pilosator collected at the same site a month later. While these males are likely P. pilosator, we could not find anything morphological in our examination of these males that connects them to the P. pilosator female.	en	Bass, Amber, Bennett, Andrew M.

3159D046214EA9F8BA1EA59D90CC45B2.taxon	discussion	There is one male specimen collected in 1938 in British Columbia. This male could not be associated with a female or unequivocally determined to be a new species. Geographically, this male is more supported as P. variegata as it was collected ~ 380 km from the type locality of this species in contrast to ~ 1700 km from P. maculata. However, given how little we know about the distribution of North American species, this alone is not evidence enough to associate it. Identification utilizing molecular data was not possible due to the age of the specimen and the lack of DNA of the two other North American Piogaster species which are known only from the holotype. To confidently associate this male with either P. variegata or P. maculata, multiple shared morphological characters are required and were not observed in this study and thus it remains identified only to genus. Nevertheless, we provide a diagnosis and description of this specimen to aid future researchers should additional material be found that will allow clarification with respect to its status. This is the specimen mentioned in Gauld and Dubois (2006) as Piogaster sp. 1. It was reared from Habronattus, providing a new generic host record for Piogaster and, to our knowledge, is the only specimen with associated host remains (Figs 23 E, 23 F).	en	Bass, Amber, Bennett, Andrew M.

3159D046214EA9F8BA1EA59D90CC45B2.taxon	diagnosis	Diagnosis. This specimen can be distinguished from congeners by possession of the combination of the following: 1) Metasoma with T 1 – T 5 weakly granulate (Fig. 23 C), 2) HW 2 / Cu absent with no apparent bend in 1 / Cu & cu-a (Fig. 23 A); 3) T 6 – T 8 smooth, subpolished (Fig. 23 C); 4) FW vein 2 rs-m short, ratio of 2 rs-m to M between 2 rs-m and 2 m-cu 0.3 (Fig. 23 A). This specimen is most similar to P. variegata and P. maculata with respect to the granulate metasoma and the unbent HW vein 1 / Cu & cu-a, but differs in T 6 – T 8 being smooth and subpolished rather than granulate and matte, and the 2 rs-m vein being short.	en	Bass, Amber, Bennett, Andrew M.

This specimen was collected as part of the Forest Insect Survey, a project that ran from 1936 – 1961 (and continued until 1995 as the Forest Insect and Disease Survey) with the goal of documenting Canadian forest insect fauna (van Sickle et al. 2001). The specimen locality is listed as Goat River, BC. According to the Canadian Geographical Names Database there are three Goat Rivers in British Columbia (Natural Resources Canada 2021). In 1938, 345 of the 442 insect samples collected in British Columbia as part of the Forest Insect Survey were collected by the BC Forest Service (Dominion Forest Service 1939). By accessing archival records of BC Forest Service staff, we determined that the collector of the specimen, H. Webb, was an assistant ranger stationed at Goat River in the Prince George Forest District from April 30 until September 30 in 1938 (British Columbia Forest Service 1920 – 1964). Therefore, the specimen was almost certainly collected at the Goat River that drains into the Fraser River near McBride, British Columbia, as it is the only Goat River in the Prince George Forest District (Fig. 29). An attempt was made to slide mount the exuvia; however, the resulting preparation appears to be from a sub-mature instar (D. Wahl, pers. comm.). Therefore, the last larval cephalic sclerites of Piogaster remain unknown.	en	Bass, Amber, Bennett, Andrew M.
