Original type series
Holotype ♀, by monotypy (ANSP). Cresson (1868, p. 92) clearly stated that the description was based on only ‘ one ♀ specimen’ from New York. This specimen can be referred to as the holotype designated by monotypy (ICZN 1999, Article 73.1.2).
Type locality
United States of America, New York.
Type specimens examined (Figures 38a, 40a–c)
Holotype: ‘[White label] N. Y. // [White label] ornatus /Cres. // [Red label] TYPE No./ 1244 – ’ (specimen examined).

Updated distribution (Figure 6)
MEXICO (Berthoumieu 1904); UNITED STATES OF AMERICA: Florida (Heinrich 1977), Georgia (new state record), Iowa (Heinrich 1962b, wrongly mentioned as Idaho, see Comments), Illinois (Nason 1905), Maryland (Townes and Townes 1951), Massachusetts (Carlson 2011), New York (Cresson 1868), North Carolina (Heinrich 1962b).
Host
Unknown.
Male
The first description of a male was provided by Heinrich (1962b, p. 790), who referred to the specimen as the neallotype and stated that the specimen was tentatively placed under Ambloplisus ornatus because of the colour variation between the two sexes. The association was later confirmed by Heinrich (1977, p. 277), who collected on the ‘same small bush’ first the female and subsequently thereafter the male.
Comments
Townes and Townes (1951, p. 281) reported the species for Maryland (not recorded by Yu et al. 2016), New York, and New Jersey. However, the New Jersey record belongs to Tropicolabus foxi (Davis, 1898), a species that was synonymised under Ambloplisus ornatus by Townes (1944, p. 314) (as Platylabus foxi), and later resurrected by Heinrich (1959, p. 216), who placed it under the newly described genus Tropicolabus Heinrich (see below). Therefore, Ambloplisus ornatus is not known for New Jersey.
The records from Massachusetts and Ohio are from BugGuide and identified by Carlson (2011) as Ambloplisus ornatus. However, these have not been recorded in any paper or catalogue (see Yu et al. 2016). Another record missing from Yu et al. (2016) is the one from Illinois by Nason (1905, p. 149) whose specimens were identified by the Ichneumonid expert G.C. Davis.
Heinrich (1962b, p. 790) reported a specimen in the USNM from Idaho, but as noted by Carlson (1979, p. 547), who analysed the same specimen, the actual locality is in Iowa. Unfortunately, Yu et al. (2016) listed Idaho as a locality for the species, without mentioning Iowa.
Berthoumieu (1904, p. 30) reported the species ‘ Hoplismenus ovatus Cress’. for Mexico. We are not aware of Cresson having used the name ovatus for a species in this insect group, and all other circumstances suggest that Berthomieu must have had H. ornatus in mind. Therefore, and in agreement with Townes (1944, p. 314), we regard H. ovatus as an incorrect subsequent spelling of Hoplismenus ornatus Cresson, 1868 (ICZN 1999, Article 33.3). Yu et al. (2016) failed to report Berthoumieu (1904) and Mexico was not included in the distribution of the species.
