Ischnosoma flavicolle
(LeConte, 1863)
Ischnosoma flavicolle is a of rove beetle in the Staphylinidae, Tachyporinae. Originally described by LeConte in 1863 as Mycetoporus flavicolle, it was transferred to the Ischnosoma in a 1991 taxonomic revision of North and Central American Mycetoporus and Ischnosoma. The species is known from eastern North America, with records spanning from Canada to the southeastern United States. A lectotype was designated for this species in the 1991 revision.

Identification
Ischnosoma flavicolle can be distinguished from Mycetoporus by the diagnostic generic characters of Ischnosoma, including the structure of the pronotum and elytral . Within Ischnosoma, it belongs to a species group characterized by particular morphological features detailed in the 1991 revision. The specific epithet "flavicolle" refers to the yellowish pronotum. Precise identification requires examination of male genitalia and other microscopic characters detailed in the original taxonomic description and revision keys.
Distribution
Eastern North America: Canada (New Brunswick, Ontario, Quebec) and United States (Alabama, Arkansas, District of Columbia, Florida, Georgia, Illinois, Kansas, Kentucky, Louisiana, Massachusetts, Maryland, Missouri, Mississippi, North Carolina, New Hampshire, New Jersey, New York, Oklahoma, Rhode Island, South Carolina, Tennessee, Texas, Virginia, Wisconsin).
Similar Taxa
- Ischnosoma pictumFormerly classified in Mycetoporus; shares generic transfer history and eastern North American distribution. Distinguished by color pattern and male genitalia.
- Ischnosoma splendidumFormerly Mycetoporus splendidum; similar preferences and geographic range. Separated by elytral punctation and body proportions.
- Mycetoporus speciesHistorically confused with I. flavicolle before 1991 revision; distinguished by pronotal structure, elytral , and other characters detailed in generic key.

Nomenclatural history
This was originally described by John Lawrence LeConte in 1863 as Mycetoporus flavicolle. It remained in that for over 125 years until Klimaszewski's 1991 revision transferred it to Ischnosoma based on morphological evidence. A lectotype was designated from LeConte's original material to stabilize the name.
Taxonomic uncertainty
, , and precise requirements for this remain poorly documented. The 1991 revision noted that biological data were largely unknown for most Ischnosoma species, with collection records providing the primary source of distributional and seasonal information.
