- Baeus anelosimus Margaría, C. B., 2006, Zootaxa 1162: 46-49.
Description
(Figs. 2-6).
Diagnosis
Diagnosis Female body yellow ochraceous; antennal club longer than A2-A6 with visible segments. Male body color chestnut brown, metasoma lighter and appendages yellowish, wings hyaline relatively narrow; digitus with three small teeth, aedeagal lobe and aedeagal-volsellar shaft combined near twice length of basal segment. Baeus anelosimusHNS n. sp. is related to B. platensisHNS by antennal morphology.

Antenna (Fig. 3). Antennal segments in the following relative proportions (46:11), (22:12), (8:7), (3:7), (5:7), (5:9), (13:20), (9:26), (7:25), (8:21), (9:13), antennal club longer than A2-A6 (46:43). Mesosoma. In dorsal view with fine polygonal sculpture, wider than long (18:12); mesoescutum transverse (18:10); scutellum and metanotum stripe like; mesonotum with short semidecumbent pilosity. Metasoma.

In lateral view higher than long (24:20). Wings. Fore wings hyaline, relatively narrow, length:wide (70:19), apically rounded, overlapping the apex of metasoma; stigmal vein as in Fig. 6; hind wings hyaline with setae slightly longer than wing width. Metasoma. Metasoma in dorsal view longer than high, with first tergite trapezoidal, wider than long (13:4), with longitudinal costae; T2 wider than long (21:10), with costae in the posterior portion of the segment. Genitalia. Digitus with three small teeth, penis valves and ventral portion of aedeagalvolsellar shaft without sclerotization; volsellar laminae developed as a weakly ventral plate; aedeagal lobe and aedeago-volsellar shaft combined near to two times length of basal segment.
