NAME DERIVATION.— Carinatus, Latin for carinate; with reference to the carinate propodeum of his species.

RECOGNITION.— Aulacophilinus carinatus is an all black inhabitant of New Guinea with three submarginal cells. It differs from its three other New Guinean congeners with these characters, A. amblygnathus , solitarius , and tegularis , in having the propodeum with a longitudinal carina that separates the side from the dorsum and the posterior surface, and with s series of transverse ridges meeting the carina on its dorsal side ( Fig. 19 ). In the three other species, the longitudinal carina is absent or evanescent, and the transverse ridges on the sides of the propodeal dorsum are lacking or are evanescent. Unlike A. amblygnathus , the punctures of the frons are no more than one diameter apart (rather than 2–3 diameters apart), and unlike A. tegularis the tegula is impunctate posteriorly (rather than uniformly punctate throughout).

DESCRIPTION.— Frons dull, punctate, punctures no more than one diameter apart. Free margin of clypeal lobe obtusely angulate to rounded ( Fig. 18 ). Width of labrum equal to 1.3 × midocellar diameter. Scutum not foveate along flange, with short, inconspicuous, longitudinal ridges adjacent to posterior margin; scutal punctures well defined, almost contiguous. Scutellum slightly foveate along anterior margin. Tegula impunctate (only aciculate) in posterior half. Mesopleural punctures well defined, less than one diameter in female, some punctures about one diameter apart in male Propodeum with longitudinal carina separating side from dorsum and posterior surface and extending from gastral socket area toward spiracle ( Fig. 19 ); dorsum obliquely ridged, punctate between ridges (ridges becoming more conspicuous as they meet longitudinal carina); side punctate and somewhat irregularly ridged; posterior surface with well defined punctures, transversely ridged in ventral half. Forewing with three submarginal cells. Posteroventral forefemoral surface minutely punctate, punctures more than one diameter apart. Hindcoxal dorsum with outer margin obtusely carinate. Outer surface of hindtibia with fine but well defined spines. Punctures of tergum I fine in female, well defined in male, several diameters apart anterior of apical depression.

Setae silvery, suberect on frons, about 0.5 × midocellar diameter long in female, up to one diameter in male; appressed on postocellar area, subappressed on scutum and about 0.3 × as long as midocellar diameter in female, as 0.5 × diameter in male; suberect on tergum I and up to about 0.5 × midocellar diameter long; on lower gena erect and up to one midocellar diameter long; not concealing integument on clypeus in female, concealing in male. Apical depressions of terga with silvery, setal fasciae (fasciae ill defined in female).

Body all black.

♀.– Upper interocular distance equal to 0.62 × lower interocular distance; ocellocular distance equal to 0.3 × hindocellar diameter, distance between hindocelli equal to 1.0 × hindocellar diameter; eye height equal to 0.98 × distance between eye notches. Dorsal length of flagellomere I 2.1 × apical width. Length 6.2 mm; head width 1.8 mm.

♂.– Upper interocular distance equal to 0.60 × lower interocular distance; ocellocular distance equal to 0.5 × hindocellar diameter, distance between hindocelli equal to 0.8 × hindocellar diameter; eye height equal to 1.06 × distance between eye notches. Dorsal length of flagellomere I 2.4 × apical width. Sternum VIII: ( Fig. 20 ). Genitalia: ( Figs. 21, 22 ). Length 6.3 mm; head width 2.0 mm.
