One male has a symphysocery affecting A8–A9 of the left antenna. The fusion between these antennomeres is complete, with no traces of articulation, except for a small depression in the middle of the newly formed segment. The length of the teratological antenna is slightly shorter than the length of the normal one; this is largely due to the length of the fused antennomeres (A8–A9) being shorter than the length of A8 and A9 taken together in the normal antenna. A4 of the normal antenna has a more expanded outer apical corner than in the teratological antenna ( Figure 1 View Figures 1–13 ). In the teratological antenna, the width of A4 and A5 is a little smaller than the width of A4–A 5 in the normal antenna, and, by contrast, the width of A6–A10 is a little bit greater than the width of the same antennomeres in the normal antenna ( Figure 2 View Figures 1–13 ).
One male with a helicomery affecting the second and third gastral tergites ( T2 – T3 ) was observed, the limit between these tergites being almost impossible to establish ( Figures 14 and 15 View Figures 14–21 ). The rest of the gaster is unaffected. The sternites are not affected, but the second right laterotergite has a well-developed overlap over a very small area of the second sternite .
One male has the A5–A6 of the right antenna connected by a weak sclerotized membrane ( Figure 5 View Figures 1–13 ). While the antennomeres can still be distinguished, they appear to be rigidly joined, so there is no functional articulation. In this case, the teratological antenna is not so different in size from the normal one, with only negligible differences between the length of the 2 antennae and between the length and width of the corresponding antennomeres ( Figure 6 View Figures 1–13 ).
One gynandromorph specimen ( Figure 16 View Figures 14–21 ) was identified (transversal gynandromorphy). It looks like a female, but both antennae are 10-segmented ( Figures 17 and 18 View Figures 14–21 ). In Scelio , the number of antennomeres is dimorphic (10 in males and 12 in females). The ovipositor and ovaries were found by dissecting the specimen. The right antenna does not differ from a male antenna ( Figure 18 View Figures 14–21 ), but the left one is slightly wider ( Figure 17 View Figures 14–21 ), being intermediate in shape between a male and female antenna.
One male shows a double symphysocery of the right antenna ( Figures 3 and 9 View Figures 1–13 ). This malformation affects A3– A5 and A7–A9 ( Figure 3 View Figures 1–13 ). The malformed right antenna is shorter (2.2 mm without scape) than the normal antenna (2.6 mm without scape). A3–A5 are completely fused on the dorsal side, but on the ventral side a trace of the articulations between them can be seen. A7–A9 are not as modified as A3–A5. In the teratological antenna A2, A4– A8, A10, and A11 are noticeably shorter, while A2–A6 and A8 are wider than the corresponding antennomeres of the left antenna. Thus, for Sceliomorpha , in the teratological antenna, the affected antennomeres are shorter and wider than the normal antennomeres, and the tyloids from A4 and A5 seem to be modified, being morphologically closer to the basiconic capitate peg sensilla that are present on the female antenna.
Triteleia peyerimhoffi (Kieffer, 1906)
One female has a hypertrophied interantennal prominence and central keel on the frons ( Popovici et al., 2011). In the affected female, the distance between toruli is almost twice that in the normal specimens. Except for this malformation, the rest of the specimen is perfectly normal ( Figures 10 and 11 View Figures 1–13 ).
Pteromalidae ( Figures 22–30 View Figures 22–30 )
Norbanus africanus Subba Rao 1973
Cyclopy and head asymmetry can be observed in one female that has only the right compound eye present, the left being completely absent ( Figure 23 View Figures 22–30 ). The area where the eye should have been displays normal sculpture, except for a tiny oval structure, and has the same coloration as the rest of the head capsule; however, this side of the head is evidently smaller (less high) than the right side. Another female from the same sample displays a hypertrophy of A6–A8 of the left antenna, each of these antennomeres being distinctly swollen and darker compared to the corresponding antennomeres of the right antenna ( Figure 22 View Figures 22–30 ).
One female is characterized by a symphysocery affecting A8–A10 of the right antenna ( Figure 25 View Figures 22–30 ), the left one being normal ( Figure 26 View Figures 22–30 ). The 3 antennomeres are fused only on the ventral side; on the opposite side their limits are clearly visible ( Figure 25 View Figures 22–30 ).
One female has the gastral petiole clearly asymmetric and wider than normal. The asymmetry is especially visible at the level of the 2 lateral projections of the petiole and at its connection with the gaster ( Figure 24 View Figures 22–30 ).
Systasis parvula (Thomson, 1876)
One female has both antennae affected by malformations. The right antenna ( Figure 28 View Figures 22–30 ) has a symphysocery affecting all funicular segments (A5–A9), while the left antenna has a symphysocery affecting A4– A5 and a hypertrophy of A5, which appears as if another antennomere is fused laterally with it ( Figure 27 View Figures 22–30 ). One male has a hypertrophy of A5 at the level of the left antenna ( Figure 29 View Figures 22–30 ). However, the 2 anelli cannot be observed, which may also indicate a symphysocery affecting A3–A5. Additionally, the pedicel (A2) looks displaced ( Figure 29 View Figures 22–30 ). The right antenna is normal ( Figure 30 View Figures 22–30 ).
