Lectotype designation for B. sociabilis . All specimens bear labels with original data of locality, date and collector. Blanchard (1937) mentioned as “habitat” of B. sociabilis the localities of Loreto in Misiones province, and Chaco province, but did not provide an explicit mention of the type-locality. To determine which specimens constitute the type series (ICZN 1999: Art 72,4.1.1.), we have taken into account the presence of original labels indicating the type-status. The specimens collected in Loreto bears the labels indicating their type condition.

Labels are quoted verbatim, lines separated by slash. Lectotype and paralectotypes were labeled with a red label, accordingly.

LECTOTYPE male (INTA) glued on card ( Fig. 1 ), and legs, wing & terminalia on plastic cards pinned with the specimen ( Fig. 2 ); with the following labels ( Fig. 3 ): “Loreto / 26/XII/1935 / Ogloblin” handwritten on white paper, black frame; “S/ guavita / Eugenia / sp.” handwritten on white paper, black frame; “ Bithoracochaeta / sociabilis / Blnchd.
