Nannotanyderinae: A new subfamily of Tanyderidae (Diptera)

Kornelia Skibińska

Plain Language Abstract

After analyses of fossil and extant representatives of family Tanyderidae, they have been divided into two separate evolutionary lines — Tanyderinae Osten-Sacken, 1879 and Nannotanyderinae subfam. nov. A new genus and species is described based on material from the Eocene Baltic amber.

Resumen en Español

Nannotanyderinae: una nueva subfamilia de Tanyderidae (Diptera)

Se examinaron los caracteres de la venación de ala y los genitales masculinos para los representantes fósiles y existentes de la familia Tanyderidae. A partir de la evidencia morfológica, se plantea la hipótesis de que existen dos linajes evolutivos separados a nivel de subfamilia, a saber, Tanyderinae Osten-Sacken, 1879 y Nannotanyderinae subfam. nov. Se establecen las diferencias entre ellos. Se describe e ilustra un nuevo género y especie del ámbar eoceno del Báltico.

Palabras clave: sistemática, taxonomía, ámbar báltico, fósiles de Diptera, nueva subfamilia, nueva especie.

Résumé en Français

Nannotanyderinae : une nouvelle sous-famille de Tanyderidae (Diptera)

Les caractères décrivant la nervation des ailes et les organes génitaux des mâles ont été examinés chez des représentants fossiles et actuels de la famille Tanyderidae. D'après la morphologie, nous émettons l'hypothèse selon laquelle deux lignées évolutives séparées existent au niveau sous-familial : Tanyderinae Osten-Sacken, 1879 et Nannotanyderinae subfam. nov. Les différences entre ces deux sous-familles sont présentées. Une nouvelle espèce (appartenant à un nouveau genre) de l'ambre éocène de la Baltique est décrite et illustrée.

Deutsche Zusammenfassung

Nannotanyderinae: eine neue Unterfamilie der Tanyderidae (Diptera)

Es werden die Flügel-Nervatur und Merkmale der männlichen Geschlechtsorgane bei fossilen und heutigen Vertretern der Familie Tanyderidae untersucht. Aufgrund morphologischer Nachweise wird angenommen, dass zwei separate Evolutionslinien auf Subfamilienlevel existieren, nämlich Tanyderinae Osten-Sacken, 1879 und Nannotanyderinae subfam. nov. Es werden die Unterschiede zwischen den beiden Subfamilien angegeben. Eine neue Gattung und Art aus dem eozänen Baltischen Bernstein wird beschrieben und illustriert.

Key to Subfamilies

1. Gonopods of male genitalia with gonocoxites and gonostyli remarkably elongate, more than six times longer than wider; gonocoxites and gonostyli with a longitudinal row of prominent, spiniform setae on their mesial surface (Figure 3.1, Figure 9.2, Figure 10.2, Figure 11.2, Figure 12.2, Figure 14.2, Figure 16.2); wings in fossil species small (up to 4 mm length) (Figure 4, Figure 5, Figure 6, Figure 7, Figure 8, Figure 10.2, Figure 12.2, Figure 14.2) NANNOTANYDERINAE
subfam. nov.
  − Gonopods of male genitalia with gonocoxite shorter, usually about three of four times as long as wide, and broad at base gonocoxites and gonostyli without prominent spiniform setae; wing usually medium or large size (7-20 mm); (Figure 3.2) TANYDERINAE
Osten-Sacken, 1879

 

Key to Genera

1. Vein Sc longer than half wing length (Figure 16.1); rostrum elongated (Figure 15), longer than the combined length of head and thorax. Peringueyomyina
Alexander, 1921
  - Vein Sc reaching half wing length or shorter; head without developed rostrum 2
2. Vein R2 short, several times shorter than length of vein R2+3; vein Sc ending opposite or very close to fork of vein Rs into R2 and R3; at rest, gonopods about 3/4 abdomen length; (Figure 4Figure 5Figure 6Figure 7Figure 8Figure 10) Nannotanyderus
Ansorge, 1994
  - Vein R2 evidently longer than R2+3; vein Sc ending before fork of R 2+3 into R2 and R3; gonopods shorter than 3/4 abdomen length 3
3. Vein Sc ending almost opposite one third length of R 2+3; vein R2 about twice as long as Rs; aedegal complex conspicuous; (Figure 13, Figure 14) Coramus
gen. nov.
  - Vein Sc ending opposite two third length of Rs; vein R2 about one fifth length of Rs; complex inconspicuous (Figure 12) Dacochile
