Gryonoides Dodd, 1920

Gryonoides Dodd, 1920: 360 (original description. Type: Gryonoides pulchellus Dodd, by original designation), Dodd, 1930: 42 (keyed); Fouts, 1948: 92 (keyed); Muesebeck & Walkley, 1956: 356 (citation of type species); Masner, 1976: 70, 74 (description, keyed); Johnson, 1992: 513 (cataloged, catalog of world species); Austin & Field, 1997: 46, 68 (structure of ovipositor system, discussion of phylogenetic relationships); Talamas, Mikó and Copeland 2016: 7 (keyed).


Gryonoides was diagnosed from two other taxa with lateral mesoscutellar spines, Dvivarnus Rajmohana and Veenakumari and a species in the Trimorus carus group, by Talamas et al. (2016). The elongate clypeus and torular triangle of Gryonoides are shared with the undescribed species in the T. carus group, whereas the presence of the proximal projections of cercal plates (pac: Fig. 2A View Figure 2 ) is shared with Dvivarnus (Fig. 3A View Figure 3 ). Additional diagnostic characters can be found in the ovipositor assembly: Gryonoides differs from Dvivarnus and the T. carus species group in the presence of a resilin rich sclerotized bridge (based on its blue autofluorescence in response to 405 nm excitation wavelength and strong red fluorescence in response to 488 nm laser) connecting the lateral arms of T7+8 (brg, la: Figs 2A View Figure 2 , 2B View Figure 2 ). Gryonoides males and females exhibit a unique sexual dimorphism in the ratio of the length of the radicle and the scape. Whereas in other scelionid species, the ratio is the same in males and females, in Gryonoides , the female radicle is longer than that of the male relative to the length of the scape (Figs 1A, B View Figure 1 ). It should also be noted that Gryonoides has a strictly Neotropical distribution whereas other teleasines with lateral mesoscutellar spines are not known from this region.
