|Title||A new species of Thaumamannia from Surinam (Heteroptera, Tingidae, Vianaidinae)|
|Abstract||During soil fauna investigations performed in 1959 by Dr. J. van der Drift (see his study, 1963), three specimens were collected of a small coleopteroid heteropteron, representing a new species belonging to the genus Thaumamannia Drake & Davis, 1960. Up till now, only one other species in this genus was known, viz., T. manni, collected in an ants' nest by Mr. W. H.|
Mann in Bolivia. The other three known species in the subfamily Vianaidinae1) belong to the genus Anommatocoris China, 1945, and are also found with ants (Drake & Ruhoff, 1965). The new species described here is closely related to the Bolivian species, and in all likelihood is also myrmecophilous.
It is the first record of a vianaidine tingid for Surinam and for the Guyana's.
The writer's thanks are tendered to Dr. J. van der Drift, who placed the Heteroptera specimens at the writer's disposal, and after whom the new species is named.
Thaumamannia vanderdrifti n. sp. (figs. 1-11) Diagnose. — Small (2mm), brown, shining, broadly ovate, convex, coleopteroid, brachypterous, dorsally densely and deeply punctate and covered with long, curved hairs. Sides of pronotum and costal area of elytrae extended horizontally (paranota). Closely related to T. manni Drake & Davis, 1960, but differing in the following characters: Anterior and lateral parts of pronotum also deeply punctate, posterior corners rounded.
Paranota of elytrae narrowed basally. The carina-like vein on elytrae longer, almost reaching elytral commissure near apex of wing. Lateral branch of metasternal scent gland ostiole extending laterally far beyond costal margin of elytrae.
Male (figs. 3, 5-7). — Head convex, tylus strongly convex, protruding,
