Areotetes carinuliferus sp. n.

Etymology.

From “areola” (Latin for “room”) and the generic name Utetes Foerster, 1862, because it is similar but has an areolate propodeum. Gender: masculine.

Diagnosis.

Hind tibia with a long nearly straight carinula basally (Figs 39, 47, 59); face without tubercles; in front of anterior ocellus without a distinct semi-circular or triangular depression; frons without a pair of distinct depressions above antennal sockets; occipital carina present laterally, not or slightly curved ventrally and remaining removed from hypostomal carina, near level of middle of eye straight or nearly so, without transverse carina or crest; clypeus more or less convex and high (Fig. 48); labrum normal, without emargination ventrally; hypoclypeal depression distinct (Fig. 48); malar suture absent; scapus, fore coxa and trochanter at most weakly compressed; epistomal suture without large depressions; mandible normal, triangular (Fig. 51); pronotum short and subvertical; pronope absent or obsolescent; side of pronotum anteriorly below groove with distinctly elevated area; medio-posterior depression of mesoscutum rather small (Fig. 34) or absent (e.g. in Areotetes carinuliferus); scutellar sulcus usually rather wide (Fig. 34); propodeum areolate and smooth between carinae, with medium-sized medio-longitudinal carina (Figs 35, 44, 56); precoxal sulcus smooth or finely crenulate; postpectal carina completely absent; vein 2-SR of fore wing present; first subdiscal cell of fore wing at least partly closed by vein 3-CU1 and short vein CU1b postero-apically (Figs 33, 43, 53); vein 1-M of fore wing straight or slightly curved and vein 1-SR short; vein cu-a of hind wing present and vein m-cu absent; vein 3-SR of fore wing distinctly longer than vein 2-SR (Figs 33, 43, 53); length of fore wing less than 3.5 mm; second tergite without sharp lateral crease, smooth or striate; length of second and third tergites combined less than 0.7 times length of metasoma behind first tergite; fourth and following tergites (at least partly) exposed; ovipositor sheath about 0.1 times as long as fore wing. According to Fig. 6 not closely related to the genus Utetes Foerster, despite having carinulae of the hind tibia in common.

Biology.

Unknown, butthe related genus Utetes Foerster, 1862, contains parasitoids of fruit infesting Tephritidae and to a lesser degree of Agromyzidae and Anthomyiidae; at least some of the host records may be the result of misidentification of the host or parasitoid.

Notes.

Can be separated from Utetes Foerster as follows:

1Epicnemial area crenulate; pronope slit-shaped and deep; clypeus thin and protruding ventrally; vein m-cu of fore wing far postfurcal; posterior face of propodeum without areolation; medio-longitudinal carina of propodeum short or absent; precoxal sulcus usually widely crenulate; length of fore wing often more than 3.5 mmUtetes Foerster sensu stricto
Epicnemial area smooth; pronope round, if slit-shaped then indistinctly developed; clypeus obtuse and truncate ventrally; vein m-cu of fore wing slightly postfurcal; posterior face of propodeum with areolation; medio-longitudinal carina of propodeum medium-sized; precoxal sulcus smooth or finely crenulate; length of fore wing less than 3.5 mmAreotetes van Achterberg & Li, gen. n.
