Victoriana parvicornis View in CoL species group

Ocyptamus parvicornis species group. Thompson (1981)

Description. *Body orange ( Fig. 49 View FIGURES 48–60 ). Head. Face pale and of normal width (~1/3 of head width); tubercle ventrally positioned. Frons very narrow (~1/4 of head width). Antennal insertions confluent. Female ocellar triangle adjacent to lateral eye margin. Dorsal occiput with 2 rows of pile. Thorax. Scutum without distinct anterior row of pile. Anterior anepisternum pilose. Katatergite with inconspicuous microtrichia. Metaepisternum pilose. Metasternum bare. Upper calypter margin bare. Metafemur with normal pile. Wing. Alula very narrow and inconspicuous (narrower than c cell). Wing mostly hyaline, sometimes with dark apical spot. Abdomen. Abdomen petiolated and narrow, orange and without colour pattern ( Fig. 49 View FIGURES 48–60 ); *male sternum 5 with pair of apico-lateral extensions ( Fig. 57 View FIGURES 48–60 ). Terminalia. Female tergum 7 divided into a pair of quadrangular sclerites ( Fig. 101 View FIGURES 89–102. 89 ); tergum 8 rectangular and with setae ( Fig. 101 View FIGURES 89–102. 89 ); cercus without pile but with homogenously distributed setulae. *Male sternum 8 with basal long projection ( Fig. 57 View FIGURES 48–60 ); *epandrium closing around cerci, without apical gap ( Fig. 58 View FIGURES 48–60 ); *surstyli asymmetrical and connected medially by a sclerotized bridge ( Fig. 58 View FIGURES 48–60 ); hypandrium compact *with very short postgonite with concave apical margin ( Fig. 60 View FIGURES 48–60 ); phallus heavily sclerotized and enlarged, *distiphallus hood-shaped ( Fig. 59 View FIGURES 48–60 ).

Included species (2). V. ferruginea ( Thompson 1981) comb. nov. [2], V. parvicornis ( Loew, 1861) comb. nov. [1b, 3, 4].

Comments. The female of the V. parvicornis species group differs from congeners in that the epiproct is divided into a pair of distinct plates ( Fig. 101 View FIGURES 89–102. 89 ). The setulose (not pilose) female cercus ( Fig. 101 View FIGURES 89–102. 89 ) is also quite distinct, however similar cerci occur in the genus Relictanum . There are undescribed species of Fragosa (e.g. USN-MENT01243085) with apical extensions on sternum 4 instead of 5 ( Fig. 57 View FIGURES 48–60 ), but these are medial and not lateral as in the V. parvicornis group.
