description: Toechorychus abactus (Cresson, 1874)   
(Not illustrated)  
 Mesostenus abactus Cresson, 1874: 151, 160 (Key, description).   
 Mesostenus abactus Cresson 1916: 13. Lectotype designation. Lectotype ♀ (ANSP, not examined), Type locality: Mexico, Mirador.   
 Toechorychus abactus: Townes 1946: 30, 49 (Host); Townes & Townes 1966: 96 (Synonymic list); Yu & Horstmann 1997: 290 (Listed); Kasparyan & Ruíz 2008 (Host); Yu et al. 2005 (Listed).   
 Original description. FEMALE. Black, with the following white marks: face, mouth, orbits, scape ventrally, broad annulus at flagellum, collar, tegula, median stripe at mesopleuron, scutellum, axillary carinae, subalar ridge, upper division of metapleuron, two lateral longitudinal marks at posterior portion of propodeum, mesopleuron except around hypoepimeron, all coxae, except hind coxa ventrally and dorsal stripe, anterior portion of T1, posterior margin of T1–8. Wings hyaline; legs pale honey-yellow; all t5 black. Opaque central lobe of mesoscutum finely transversally aciculated; propodeum rugose, tubercles transverse, very blunt; areolet very minute, open.   
 Male. Unknown.   
 Comments. The lectotype could not be examined, and none of the examined specimens seemed to fit convincingly the available characterization for this species (literature information). Since its identity could not be fully ascertained, T. abactus is here maintained as a valid species. The only known specimen for T. heredius sp. nov. was identified as T. abactus by Ian Gauld in 2001 (label data), but it can be safely differentiated from the new species by having transverse tubercles at the posterior portion of propodeum (vs. absent in T. heredius sp. nov.); mesopleuron without black marks except around hypoepimeron (vs. with rounded black spot just behind dorsal portion of epicnemial carina); sternaulus white (vs. posterior half black); legs entirely pale yellow, except for t5 of all legs black (vs. fore and mid tarsi dorsally brown); and anterior portion of T1 white (vs. dorsally black).   
 Distribution. Mexico and Guatemala. Recorded from four localities from Mexico (Nuevo León, Tamaulipas, Jalisco) (Kasparyan & Ruíz 2008) to Guatemala (Guatalón) (Townes 1946) (Fig. 200). These records comprise a range of 11°46’ in latitude.   
 Biology. Townes (1946) cites a short series of T. abactus deposited in the USNM that was reared from Mischocyttarus capixaba (Vespidae, Polistinae) at Mocá, Guatalón, Guatemala (14°40’N 89°24’W). Some specimens also emerged from Mischocyttarus pallidipectus (Smith) at Jalisco, Mexico (20°34’N 103°40’W) acc. to Kasparyan and Ruíz (2008).
