( Figs 367, 368 View FIGURES 367, 368 )

Litus maculipennis Ashmead 1900: 265 View in CoL . Type locality: St. Vincent Island, Saint Vincent and the Grenadines. Litus maculipennis Ashmead View in CoL : De Santis 1979: 362 (catalog, comments); Yoshimoto 1990: 24 (list).

Type material examined. Holotype male [ BMNH] on point labeled; 1. “ St. Vincent, W. I., H. H. Smith 227.”; 2. “ W. Indies – 331”; 3. “ Type Hol.”; 4. “ Litus maculipennis Ashm. ♂ Type ”; 5. “ B.M. Type Hym. 5.1445”. The specimen ( Fig. 367 View FIGURES 367, 368 ) is in poor condition (shriveled), lacking one antenna and all but three basal flagellomeres of the other antenna.

Redescription. We do not provide a detailed redescription because only the poorly preserved, pointmounted holotype is available.

Diagnosis. Gonatocerus (Cosmocomoidea) maculipennis is a member of the ater subgroup of the ater species group. The main distinguishing features based on the only known male are as follows. Body length 760 µm. Body mostly brown except petiole light brown; scape, pedicel, and most of leg segments light brown; flagellum and metatibia brown. Mesonotum smooth and shining. Propodeum ( Fig. 368 View FIGURES 367, 368 ) with two subparallel submedian carinae and lateral carinae, otherwise smooth. Forewing ( Fig. 367 View FIGURES 367, 368 ) bare behind submarginal vein, with cubital row of setae complete and a few setae between it and marginal vein, remainder of disc densely setose; disc with a brown band behind stigmal vein and a larger brownish spot in its widest part. Hind wing almost hyaline.

This appears to be a good species, but the female needs to be discovered before it can be described properly and placed in context.

Distribution. NEOTROPICAL: Saint Vincent and the Grenadines.

Hosts. Unknown.

Comments. Triapitsyn & Berezovskiy (2004) hypothesized, based solely on the original description, that Litus maculipennis might be a species of Myrmecomymar Yoshimoto , but examination of the holotype of this species proved that wrong.
