Straka, Jakub, Juzova, Katerina & Batelka, Jan, 2014, A new genus of Strepsiptera, Rozenia gen. n. (Stylopidae), a parasite of bee genera Acamptopoeum and Calliopsis (Andrenidae, Panurginae, Calliopsini), ZooKeys 442, pp. 31-49 : 35-36

Taxon classification Animalia Strepsiptera Stylopidae

Rozenia peruana sp. n. Figures 4, 7, 10

Material examined.

Holotype female puparium, in a separate microvial on same pin as host. Original label: "PERU: Lima dept. / Ricardo Palma, V-9-96 / J. G. Rozen, A. Ugarte". 1 FP, host: Acamptopoeum vagans (Cockerell, 1926), ♀, JS Ascher det., AMNH coll. (code: AMNH_BEE 00026923).

Diferential diagnosis.

Female puparium. Cephalothorax of Rozenia peruana sp. n. strongly diverging posteriorly behind head (Figure 10). Among all the species of the genus Rozenia peruana sp. n. has the smallest mandibles that, as in other species, project from the head contour. A very specific character is the shape of prothorax in dorsal view. Prothorax produced forward on lateral sides to the head margin, thus posterior head margin is sinuous (Figure 10). Prothorax is dorsally pigmented as in Rozenia platicephala sp. n.

Description.

Female. Canalis prolifer on abdominal segment I–IV, with three large tuba prolifera on segments II-IV, tuba prolifera on segment I distinct, but very small and possibly not functional.

Female puparium. Cephalothorax slightly wider than long, approx. 0.7 mm long and approx. 0.9 mm wide between spiracular corners. Head wide, approx. 0.6 mm; mandible small, projecting from head contour, intermandibular distance 0.16 mm, mandibles nearly three mandibular diameters apart; labral apex between mandibles slightly arcuate; oral ridge well-developed; epipharinx weakly divided from very short labral area; maxilla indistinct; brood opening wide, nearly from side to side, arcuate; head corners narrow, directed posterolaterally; posterolateral margin of head corner with distinct apodeme; cephalic ridge weak. Thorax without intersegmental ridges; pro-, meso- and metathorax largely fused ventrally, segments seem to be subequal in length; prothorax dorsally slightly shorter than half length of fused meso- and metathorax, prothorax strongly produced forward laterally; metathorax as well as mesothorax laterally with remnant of stigmata; metathoracic ridge ill-defined, but distinct, touching cintum and going anterolaterally to spiracle. Spiracular corners prominent, triangular, well-developed; spiracle positioned anterior to spiracular corners, turned laterally; basal band arcuate, projecting forward, but ill-defined. All cephalothorax pale, head, prothorax dorsally, sides of thorax and spiracular corner light pigmented; rest of cephalothorax pale and translucent.
