(Life: Kingdom: Metazoa (animals); Phylum: Arthropoda; Class: Hexapoda; Order: Hymenoptera;  Superfamily: Cynipoidea; Family: Liopteridae)

ClassificationLiopteridae keysCynipoidea keys


1. Forewing uniformly infuscate posterior to anterior margin; posterior margins of T3 and T4 broadly emarginate …2

- Forewing basally hyaline, with either one or two infuscate patches posterior and distal to the marginal cell; posterior margins of T3 and T4 straight, not emarginate …4


2. Ventral malar margin, immediately adjacent to mandibular base, distinctly striate ...3

- Ventral malar margin, immediately adjacent to mandibular base, gently shagreened ...Tessmannella nigra Hedicke


3. Distinct clypo-pleurostomal line present; medial facial area shagreened…Tessmannella spinosa Hedicke

- Clypo-pleurostomal line absent; medial facial area horizontally striate…Tessmannella expansa Quinlan


4. Central scutellar area smooth, with a very faint central ridge …Tessmannella copelandi Buffington & van Noort

- Central scutellar area areolate to foveate … 5 


5. Forewing with single distinct infuscate patch throughout marginal cell and immediately posterior; central scutellar area areolate; dorsal and lateral pronotum areolate…Tessmannella roberti Buffington & van Noort

- Forewing with two infuscate patches, one including the marginal cell and space immediately posterior, and a second faint patch that encompasses the entire distal margin of the wing (leaving a small, hyaline area between the distal margin and the marginal cell); central scutellar area foveolate; dorsal and lateral margins of pronotum horizontally striate, resulting a ‘wave-like’ texture…Tessmannella kiplingi Buffington & van Noort
