Abstract

A new genus and species of the braconid parasitoid subfamily Doryctinae, Palaeorhoptrocentrus kanti Belokobylskij, gen. et sp. nov., from the late Eocene Baltic amber are described and illustrated from two females. This genus is characterised by the fore wing having postfurcal position of the recurrent vein (m-cu), distally closed brachial (second subdiscal) cell, not interstitial parallel vein (CU1a), and short submedial (subbasal) cell in hind wing. Doryctomorpha tertiaria Brues, 1933 is transferred to the genus Palaeorhoptrocentrus gen. nov., P. tertiaria (Brues, 1933), comb. nov. The new genus is compared with the similar extant genera Dendrosotinus Telenga, 1941, Guaygata Marsh, 1993, and Rhoptrocentrus Marshall, 1897.

摘要

描述并展示了来自始新世晚期波罗的海琥珀中的茧蜂科寄生物亚科Doryctinae的一个新属新种——康德古拟曲角茧蜂（Palaeorhoptrocentrus kanti Belokobylskij，属名及种名均为新），标本为两只雌性。该属的特征为：前翅的回归脉（m-cu）位于翅后脉位置，臂室（第二亚盘室）远端封闭，而非间脉平行（CU1a），后翅亚中（亚基部）室短。1933年的布鲁氏第三纪多距茧蜂（Doryctomorpha tertiaria Brues）被转移至新属古拟曲角茧蜂属（Palaeorhoptrocentrus gen. nov.），成为康德古拟曲角茧蜂（P. tertiaria (Brues, 1933)，新组合）。将新属与现存的类似属——1941年的树索茧蜂属（Dendrosotinus Telenga）、1993年的瓜伊加塔茧蜂属（Guaygata Marsh）以及1897年的曲角茧蜂属（Rhoptrocentrus Marshall）进行了比较。
