Remarks
- Systematics: Research recorded significant morphological variability in adult females of T. aberrans in specimens from post-industrial wastelands. Morphological intraspecific variation in adult females was observed. The vast majority of females had eight-segmented antennae, but 11 of the collected specimens had nine-segmented antennae; the presence of eight- or nine-segmented antennae apparently was not associated with the habitat type. (Kalandyk-Kolodziejczyk et al. 2023) Differences in number of trilocular pores in C18 were observed in females collected from the four zinc-contaminated post-industrial wasteland sample sites: zinc heaps and the degraded area near the zinc production plant at Piekary Slaskie, Poland. Unusual pores were observed in a few females from only one of the post-industrial wastelands sites. Translucent pores were present on the hind coxae in all the adult females, but there were differences in the number of these pores between females collected from postindustrial wastelands and those from undegraded habitats. All of the adult females studied had two pairs of abdominal cerarii (C17 and C18), but there were differences found in the morphology of the two pairs of cerarii. The anal lobe cerarius (C18) most often contained two conical setae, two auxiliary hair-like setae and 6–16 trilocular pores. The number of trilocular pores in C18 differed between females living in different habitats. In some specimens, there was an additional (third) conical seta in C18. (Kalandyk-Kolodziejczyk et al. 2023)
- Structure: Diagnosis of adult female having the following combination of features: (i) horseshoeshaped anal ring; (ii) presence of simple tubular ducts of two types (dorsal ducts larger than those of venter); (iii) multilocular disc-pores present on both body surfaces; (iv) presence of two pairs of cerarii; (v) each anal lobe cerarius (C18) containing two conical setae, 6–16 swirled trilocular pores and three or four auxiliary hair-like setae; (vi) circulus usually absent but rarely present; and (vii) antennae each eight (or rarely nine) segmented. (Kalandyk- Kolodziejczyk, et al. 2023) Translucent pores were observed on the hind coxae of all the T. second-instar nymphs examined. These pores have been observed almost exclusively in adult females. (Kalandyk- Kolodziejczyk, et al. 2023)
- Biology: Lives in leaf sheaths of various grasses. Life history and natural enemies discussed by Kosztarab & Kozár (1988F). Lives in leaf sheaths of various grasses.
- General Remarks: Good description and illustration of the adult female given by Goux (1938a), Schmutterer (1952a), Ter-Grigorian (1973), Tereznikova (1975), Kosztarab & Kozár (1988F), Tang & Li (1988) (as Trionymus chifengensis Tang) and by Tang (1992). Good description of the adult female given by Borchsenius (1949).
