description: Apechoneura nigriventris Mocsáry, 1905 (Adapted from Flórez, 2012) (Figs 18-32, 61-80, 89 & 91)   Diagnosis  
Metasoma and most of hind legs black; areolet sessile to petiolate.  
Female: fore wing length 15.0– 16.4 mm.  
 Head   
Clypeus almost flat, with a weak transverse ridge near apex; malar space 0.6–0.8× as long as basal mandibular width (Fig. 24); lower face at narrowest point 0.9× as wide as height from clypeofacial suture to insertion of antenna; hypostomal carina joined to occipital carina far from base of mandible; posterior ocellus separated the eye by 1.3–1.5× its own maximum diameter (Fig. 27); antenna with first flagellomere about 0.9–1.0× as long as the second; subapical flagellomeres slightly elongated.  
 Mesosoma   
 Pronotum with upper hind margin swollen, forming a small conical projection; scutoscutellar groove broad and shallow; scutellum shallow, with a few weak transverse rugae posteriorly; epicnemial carina absent; sternal region of mesothorax smooth and polished; posterior transverse carina absent; metapleuron with a rather conspicuous sharp lateral projection near posterior end (Fig. 25); submetapleural carina narrow with a distinct low median denticle (Fig. 26); propodeum in profile more or less flat (Fig. 26); anterior transverse carina complete laterally, separating area spiracularis from area lateralis, mediodorsally incomplete so area basalis is not enclosed posteriorly (Fig. 25); area basalis slightly transverse; lateral longitudinal carina posteriorly absent (Fig. 25); lateromedian longitudinal carinae not present behind anterior transverse carina (Fig. 25); fore leg with tibia slightly inflated, tarsus with long hairs on inner surface; mid leg with tibia bearing several stout spines; fore wing with areolet large, from truncate (sessile) to strongly petiolate, with 2 m-cu joining it very slightly basal of middle (Figs 18, 20, 22, 28, 78 & 79); second distal cell short, with vein 1 m-cu about 0.5 of length of abscissa of Cu 1 between Rs&M and 1 m-cu (Figs 18, 20, 22, 28, 78 & 79); hind wing with the distal abscissa of Cu 1 joining cu-a clearly closer to M than to 1 A (Figs 21, 78 & 80); first abscissa of Cu 1 0.1-0.2 × as long as cu -a (Figs 21, 78 & 80).   
 Metasoma   
Tergite I slender, 3.0–4.0× as long as posteriorly broad; sternite I short, reaching about 0.3–0.4 of length of tergite, with a median swelling centrally; tergite II 1.4–2.3× as long as broad, with isolated pubescence; tergite VII mediodorsally without an indentation posteriorly; tergite VIII, in lateral view, tapered to a bluntly rounded apex, without a cornus, and with uniformly scattered pubescence (Fig. 23); tergite IX bearing long pubescence; ovipositor at rest extending beyond apex of metasoma by 3.5–4.5× the length of the hind tibia.  
 Color   
Head orange; flagellum predominantly black, two basal flagellomeres ventrally reddish. Mesosoma orange. Fore and mid legs orange; hind leg with coxa from totally to partially (basally) orange, trochanter and trochantellus black except for some small orange spots, femur, tibia and tarsus black. Metasoma black, hypopygium centrally orange. Ovipositor sheath black except for subapical whitish wide band. Fore wing hyaline, with a distinctive apical black band; pterostigma black.  
 Male (Figs 29–32, 61–73 & 89)   
Similar to the female in structure and color. Size smaller, fore wing length 13.2–13.6 mm.  
 Apechoneura nigriventris is removed from synonymy with A. nigricornis Mocsáry, because their color patterns are definitively different and re-instated as a valid species
