Tanycarpa bicolor View in CoL (Nees von Esenbeck)
( Figs. 1–6 View FIGURES 1 – 6 )
Bassus bicolor Nees von Esenbeck, 1812: 207. Neotype: female, Naturhistorisches Museum Wien, Austria (not examined).
Alysia bicolor: Nees 1834: 247 .
Tanycarpa bicolor: Fischer 1966: 326 View in CoL (redescription), Wharton 1980: 72 (redescription, range extension), Chen and Wu 1994: 136 (redescription, range extension).
Alysia (Alysia) ancilla Haliday, 1838: 227 . Synonymized in van Achterberg (1976).
Material examined. 1 ♀ China, Heilongjiang: Mohe, 26– W–2011, Minlin Zheng, 1 ♂ same data except 23–W –2011(FA- FU).
Diagnosis. Head 1.70× longer than high, with small blunt tubercles posteriorly ( Fig. 1 View FIGURES 1 – 6 ); frons almost flat and bare ( Fig. 2 View FIGURES 1 – 6 ); temple smooth, with sparse pubescence ( Fig. 2 View FIGURES 1 – 6 ); mandibular tooth 1 weakly expanded dorsally, almost parallel-sided, 2.20× longer than wide, 2nd tooth 1.50× longer than wide ( Fig. 3 View FIGURES 1 – 6 ); mesoscutum almost smooth, with only sparse pubescence between short notauli ( Fig. 5 View FIGURES 1 – 6 ); basal 1/2 of propodeum with longitudinal ridge medially that diverges into two oblique ridges, with four oblique longitudinal ridges posteriad the two oblique ridges forming large areola mesally and two areolae laterally, other parts of propodeum smooth ( Fig. 5 View FIGURES 1 – 6 ); pterostigma brown basally, pale yellow apically; r short; 2CUa slightly longer than 2cu-a; 1cu-a short, postfurcal; 1st subdiscal cell closed, apical width 2.70–3.00× longer than basal width ( Fig. 6 View FIGURES 1 – 6 ); T1 apically 2.40× wider than basal width, strongly convex.
Distribution. Austria; Bulgaria; Canada (British Columbia and Quebec); China (Jilin and Heilongjiang); Czech Republic; Germany; Hungary; Ireland; Netherlands; Poland; Russia (Kamchatka Oblast, Primor'ye Kray, Saint Petersburg); Spain; Ukraine; USA (New York).
Remarks. The most distinguishing feature of this species is the presence of tubercles on the posterior side of the head. Sexual dimorphism is evident among the specimens from China. The female mandible is shorter and broader than that of the male; the male propodeum has a complete median longitudinal carina that is present only in the basal 0.25 of the female.
Tanycarpa bicolor and T. rufinotata are the sole members of the species group characterized by a relatively short, broad pterostigma. They are separated primarily by blunt tubercles on the head (present in T. bicolor , absent in T. rufinotata ).
