Toxophora zikani ( d’Andretta & Carrera, 1950)

Figs. 6–9

Pupa. Length: 9.1 mm. Head width: 1.8 mm. Thorax width: 2.2 mm. Abdominal width: 2.5 mm, tapering to 0.6 mm at width of anal segment. Coloration: light brown; cephalic and anal tubercles and dorsal abdominal chitinous rods dark brown, darker apically; setae yellowish.

Head. Armed with two pairs of cephalic tubercles fused basally to form a concave arch. Anterior spines totally fused, except at apex ( Fig. 6 ), eight times longer than the second pair that is situated laterally ( Fig. 7 ); both pairs tapering to a sharp apex. Anterior spines with three pairs of short and thin setae, the first pair on the dorsal surface, the second pair placed laterally, near its base, and the third one ventrally, near the second pair of cephalic tubercles ( Fig. 7 ); an additional pair of setae is placed lateroventrally on the head.

Thorax. With three pairs of setae, one of them dorsally and remaining two pairs laterally placed; prothoracic spiracle heavily sclerotized, with a dark brown coloration, raised above the surface and located immediately behind the head.

Abdomen. Segment I with a complete transverse row of thin and long setae; segments II–VIII present a similar setal pattern; dorsally the chitinous rods are randomly intercalated with long and thin setae; pleura with two, three or four strong and long setae, arranged in an oblique row and sternites with four setae, laterally placed; on the last segment the anal tubercle has two pairs of spines, the ventral one two times longer than the dorsal, in a quadrilateral pattern and tapering to a sharp apex ( Fig. 8 ); ventral pair curved downwards ( Fig. 9 ). Abdominal spiracles slightly darker and more sclerotized than the surrounding area, raised above the surface and placed laterally on segments I–VII.

Hosts. Hymenoptera – Parancistrocerus sp. ( Vespidae , Eumeninae ).

Examined material. BRAZIL, São Paulo: Reserva Biológica Mogi­Guaçu, 17­III­ 1999, 1 female and its puparium, Camillo, Silva & Serrano leg. (MNRJ).
