Propleuron with medial area mainly nitid with sparse small punctations, anterior 1/3 with fine rugulose sculpturing, distal 1/3 with distal upper corner nitid and remainder area with confused lacunose sculpturing; propodeum lateral area with dorsal and ventral groove well defined and with fine confused colliculate sculpturing, anterior medial groove with same sculpturing as dorsal lateral groove, dorsal edge 1/5 as long as distal edge is high, area between lateral grooves with width 0.4X distal edge height; mesonotum with fine punctate sculpturing throughout; scutellar groove with 9 costulae; scutellum triangular in shape and nitid, lateral areas with fine well defined transverse ridges; axillar area with transverse ridges next to lunulae, making the anterior edge of lunulae poorly defined, remainder of axillae nitid; mesonotum with basal 1/2 nitid, remainder with confused rugose sculpturing except nitid posterior edge; large medial costulae shallow and not equal in size; pronotum with areaola well defined and with only sparse smooth rugulose sculpturing inside; area anterior to areola with two short submedial longitudinal carinae meeting areola closed distally by a short transverse ridge; anterolateral areas of propodeun with sparse but large, well­defined rugose sculpturing, spiracular area partially delineated by carinae posteriorly, postero­lateral areas with only a few carinulae emanating from edges; mesopleuron essentially nitid, except anterior edge punctate and posterior ventral tip with confused rugulose sculpturing, dorsal and posterior edge with a few small short transverse ridges, sternaulus nitid and depressed; metapleuron with confused fine rugulose sculpturing over anterior 1/5 plus distal 2/5, dorsal and distal edge with few small short transverse ridges, no medial pit present, remainder nitid.

Material examined. Holotype female: COSTA RICA: Puntarenas, Monteverde, San Luis, 1000–1500 m, Feb. 1994, Z. Fuentes. LN 449250_ 250850, # 2615. Holotype deposited at Instituto Nacional de Biodiversidad ( INBio), Santo Domingo de Heredia, Costa Rica.

Comments. The type specimen was collected in tropical premontane moist forest ( Gauld and Hanson, 1996, Fig. 1.01). The exact collecting locality was slightly drier and windier than the one described by Gauld and Hanson (1996). T. hanniae can be separated from T. masneri by the fifth metasomal tergum being heavily sculptured longitudinally with lineate striae, and T5 also as fully sclerotized as preceding terga. In addition, the propodeum does not exhibit extensive rugose sculpturing, but the areola is well defined and the hindwing has a more upcurved vein 2Rs.

Etymology. Gender feminine. This species is named in honor of Hannia Maria C., mother of the first author.
