ERDOSIELLA Soyka, 1956

( Figs 124–129 )

Erdösiella [sic] Soyka, 1956b: 16. Type species: Erdosiella acarensis Soyka, 1956 , by original designation.

Tanaomymar Annecke & Doutt, 1961: 25 . Type species: Tanaomymar mirum Annecke & Doutt, 1961 , by original designation. Synonymy by Fidalgo, 1992: 75.

Stenomymar Ogloblin, 1967: 184 . Type species: Stenomymar decoratus Ogloblin, 1967 , by original designation. Synonymy by Fidalgo, 1992: 7. In a footnote, Fidalgo attributed the synonymy to Yoshimoto (1990) but his paper was still in press at the time so Fidalgo must take the credit.

Tanyostethium Yoshimoto, 1990: 74 . Type species: Tanyostethium elongatum , 1990, by original designation. Syn. nov.

Diagnosis. Face without subantennal sulcus ventral to each torulus and without a pit medially next to each torulus ( Fig. 124a ); toruli separated by about their own height, or less than half their height ( Fig. 124a ) from transverse trabecula; antenna often with apical two funicle segments as wide as clava ( Fig. 125 ); propleura widely abutting each other anterior to prosternum; fore wing with or without brown bands and some microtrichia arranged in distinct rows ( Fig. 126 ); entire venation close to anterior margin of wing (costal cell extremely narrow except anterior to submarginal vein), parastigma with short, inconspicuous proximal macrochaeta, and distal macrochetae and marginal vein absent ( Fig. 126 ); propodeum with a partial median carina or entirely without ( Fig. 127 ); petiole attached posteriorly to gs 1, ovipositor and sheaths equally long and extending distinctly beyond apex of gaster ( Fig. 128 ).

Remarks. Erdosiella belongs to the Polynema group of genera. The species with the apical two funicle segments greatly widened are easy to recognize; the others, e.g., E. elongatum and some undescribed species large in size, with or without a banded fore wing. The genus is variable with uncertain limits.

Neotropical hosts. Unknown.

Important reference. Fidalgo (1992).
