Physical description
Most physical descriptions on Troutnut are direct or slightly edited quotes from the original scientific sources describing or updating the species, although there may be errors in copying them to this website. Such descriptions aren't always definitive, because species often turn out to be more variable than the original describers observed. In some cases, only a single specimen was described! However, they are useful starting points.
Description from GBIFthe Global Biodiversity Information Facility
Source: Leuctra Schusteri, A New Stonefly Species (Plecoptera: Leuctridae) Of The Leuctra Tenuis (Pictet) Group From The Southeastern Usa
Male. The 7 th abdominal dorsal process bears a simple, broadly-subtriangular lobe (Fig. 19); subtle anterolateral lobes present on some specimens. The specilla are broad basally, overall shape subtriangular and bearing prominent, laterally directed tubercles distally (Figs. 20 – 22). The subanal lobes are subequal in length to the specilla; near uniformly-narrow through length, tapering little but recurved anteriorly in the distal half, especially at tips (Figs. 21 – 22).
