Anapausis mourei sp. nov.

( Figs. 26–27)

Material analyzed. HOLOTYPE female, BRASIL, SP, Ribeirão Grande, Parque Estadual Intervales, Malaise Trap T 3, 24 º 15 ’ S, 48 º 10 ’ W, 13–16.xii. 2000, M.T. Tavares & eq. cols.

Diagnosis. The female of A. mourei sp. nov. can be immediately recognized by the large, tooth­like, well sclerotized projection mesally on T 8 + 9.

Description

Male. Unknown.

Female. Measurements (in mm). Body length, 2.48; wing length, 1.80; wing width, 0.72. Color. Regularly shining dark brown, with light brown transverse stripe on all femora and tibiae. Head elliptical, macrotrichia covering posterior 3 / 4 of occiput, microtrichia covering posterior half; eye­bridge complete; flagellum with 8 articles, single regular whorl of setae per flagellomere except for distal one, with 2 whorls; lateral ocelli about twice width of mesal one; no setae on front above antennae; labella small, maxillary palpus well developed, slender to apex, covered with setae and microtrichia, sensory pits and sensillae absent; cardo well developed. Thorax. Antepronotal setae, 32; proepisternals, 10; proepimerals, 8; spiracular sclerite setae, 8; anepisternals, 10 / 8; katepisternals, 13; mesepimerals, 6 / 3; merals, 4; subspiraculars, 4; supra­alars, 6; pedicelars, one; a number of longer scutellar setae not in regular row. Wing ( Fig. 26). M 1 long, broken at base, not converging basally towards M 2; A 1 produced; cell m 1 with 3 macrotrichia; m 2, 15; m 4, 17–21; cuA 2, 10–15; a 1, 4–5. Abdomen. S 7 and T 7 rectangular, unmodified. Terminalia ( Fig. 27 ). Similar to those of A. clivicola , with pair of small, lateral tubercular projections on S 8 with a number of setae, plus additional group of setae more anteriorly. T 8 + 9 with odd mesal, well­sclerotized projection. Terminalia characteristically devoid of microtrichia.

Etymology. This species is named after Father Jesus Santiago Moure, eminent Brazilian hymenopterist, who not only contributed to the systematics of the Neotropical bees, but also supervised a number of Brazilian entomologists.

Comments. The presence of the pair of bursae associated with S 8 in the female terminalia is shared with other Neotropical species of the genus. Anapausis mourei sp. nov. is similar to A. clivicola and to A. fuscinervis , as can be inferred from the shape of the maxillary palpus, of the proepimeron, and of the spiracular sclerite. The shape of M 1 in the wing, directed basally toward R 5, not toward M 1 + 2, is shared as well with A. clivicola sp. nov. and A. fuscinervis . The very typical sclerotized mesal tooth on the female T 8 + 9 is shared with A. fuscinervis , but the lateral setose lobes on S 8 present in A. mourei sp. nov. are shared with A. clivicola sp. nov., not with A. fuscinervis . The description of the male of A. mourei sp. nov. would help clarify the relationships of these three species within this small clade of the genus.
