abdomen often petiolate. Parapsidal furrows frequently incomplete, sometimes 
wanting. Second abdominal segment often lengthened. Sculpture most frequently 
a scaly reticulation, the lines often raised, rarely punctate. Scutellum often with 
two grooved lines, rarely with three, the scutum rarely with an incomplete grooved 
median line. Entedoninae. 
Submarginal vein usually more or less equal to the marginal, the postmarginal vein always 
wanting, rarely slightly or fully developed, the stigmal usually of moderate length, 
sometimes sessile. Abdomen very rarely petiolate. Parapsidal furrows always 
complete, the mesopleura often -without a femoral furrow. Sculpture usually very 
fine shagreening. Scutellum often with four grooves, rarely with two or five, the 
scutum frequently with a median groove. 
Scutellum with four (rarely with two or five; if without grooves, the abdomen 
petiolate) grooved lines; mesopleura with a femoral furrow, antenna* usually 
inserted near the middle of the face, the funtcle usually 3-jointed (rarely 2- 
or 4-jointed) and from one to four transverse-linear ring-joints present; 
abdomen usually sessile, rarely petiolate, never (?) with a phragma, the 
propodeum most frequently visible from above, long and with a median 
carina. Marginal fringes of fore wings rarely long, the fore wing never 
with an oblique hairless line back from the stigmal vein. Sculpture nearly 
uniform fine shagreening. Tarsi always 4-jointed, the strigils absent. 
Scutum frequently with a median groove. Metallic or nonmetallic. 
Tetrastichinse. 
Scutellum without grooved lines, rarely with a median groove; scutum rarely 
with a median groove; mesopleura often without a femoral furrow; 
antennm inserted below the middle of the face, the funiele variable, some- 
times absent or composed of ring-like joints, usually with from tw r o to 
four joints, true ring-joints rarely jjresent. Abdomen always broadly 
sessile and always (?) with a phragma, the propodeum very short and 
hidden ; marginal fringes of fore wing frequently long and often there is 
an oblique hairless line back from the stigmal vein. Sculpture fine 
reticulation, alutaceous or fine punctation or striation, not uniform. Tarsi 
usually 5-, often, 4-jointed, the strigils always (?) strongly developed. 
Nonmetallic, rarely metallic ( Ablerus ). Aphelininae.
