( Figs 16 , 17 , 50A , Appendix I)

Clistopyga fernandezi Gauld, 1991: 298 . Holotype: ♀, Costa Rica (MNCR).

Diagnosis. Clistopyga fernandezi may be distinguished from all other species of the C. calixtoi species group by the following combination of characters: female has genal orbits evenly wide and entirely white cream, almost reaching occipital carina ( Figs 16A, 16D ); mesosoma extensively dark brown and white with central part of lateral lobes of mesoscutum and mesosternum orange ( Fig. 16D–E ); tergite I of metasoma distinctively dark brow or black, laterally white cream, remaining tergites orange, without posterior defined white cream marks ( Figs 16A, 16H–I ); ovipositor 1.8–2.3× as long as hind tibia ( Figs 16A, 16G ); ovipositor sheath 1.6–2.0× as long as hind tibia. Male is characterized by having the mesosoma extensively marked with red or orange (17A, 17D–E); tergites black with white cream anterior lateral and posterior dorsal bands ( Figs 17F, 17H ); gena, in frontal view, with a conspicuously wide longitudinal concavity posterior to mandible ( Fig. 17B ) and submetapleural carina very weak, extended at most on anterior 0.3 of metapleuron ( Fig. 17D ).

Remarks. Additional characters to the description by Bordera et al. (2014) are as follow: female with hypostomal carina not lamelliform posteriorly to mandible; epomia as a very short carina or tubercle at the bottom of the submarginal depression of pronotum; anterior half of median lobe not conspicuously prominent, confluent with posterior half; propodeal spiracle about 0.11–0.13 the length to anterior end of pleural carina; hind leg with femur about 4.1–4.5× as long as high. Male with a very deep and conspicuous longitudinal wide concavity posterior to mandibular base. Metapleuron mostly reddish or orange. Tergite II 1.54× as long as wide.
