Nymphs of the stonefly genus Taeniopteryx (Plecoptera: Taeniopterygidae) of North America [Texas]

Nymphs of the nine Nearctic Taeniopteryx species were reared and studied during 1976-1978. Nymphal associations of the 839 specimens examined corresponded with the two established adult groupings, Taeniopterys burksi-maura, and T. lita-lonicera-starki complexes.

Description
Summary:Nymphs of the nine Nearctic Taeniopteryx species were reared and studied during 1976-1978. Nymphal associations of the 839 specimens examined corresponded with the two established adult groupings, Taeniopterys burksi-maura, and T. lita-lonicera-starki complexes. A key separating seven of the nine species, based primarily upon pigment patterns and abdominal setal arrangements was constructed. Taeniopteryx lita and T. starki were indistinguishable; T. burksi can be separated from T. maura when no developing femoral spur is present. Mouthparts were not species-diagnostic. Detailed habitus illustrations were made for six species. SEM study revealed that eggs of three species were 1.2-1.4 mm in diameter, with a highly sculptured chorion, generally resembling a Maclura fruit; micropyles were scattered. Taeniopteryx lita, lonicera, starki and ugola nymphs were reared and described for the first time. Previously unreported nymphal and adult distribution records are included.
