Tiny wasps, huge diversity - A review of German Pteromalidae with new generic and species records (Hymenoptera: Chalcidoidea).

Background: Despite their ecological and economic importance, hymenopteran parasitoids are severely understudied. Even in countries with a long taxonomic history such as Germany, dating back to the 18th century and including prolific figures like Christian Gottfired Nees von Esenbeck and Otto Schmiedeknecht, those species-rich groups are seldom the subject of comprehensive research efforts, leaving their true diversity unknown. This is often due to their small size of a few millimetres on average, leading to difficulties in their identification and examination.

Two new genera and six new species of Stenosini (Coleoptera: Tenebrionidae: Pimeliinae) from Myanmar (Burma), collected by Ren Fouqu.

New taxa of the tenebrionid tribe Stenosini Schaum, 1859 (subfamily Pimeliinae Latreille, 1802) from central Myanmar (Burma) in the region around Mandalay are described: Bamarosis gen. nov. fouquei sp.

New taxonomic and faunistic data on Asian species of the genus Indenicmosoma Ardoin (Coleoptera: Tenebrionidae: Lagriinae), with description of a new species from Thailand.

The tenebrionid genus Indenicmosoma Ardoin, 1964 (type species indochinensis Kaszab, 1940), subfamily Lagriinae, is distributed in Asia and Sub-Saharan Africa. Newly collected specimens from different Palaearctic and Oriental Asian regions are presented, among them also one species new to science from Thailand (Indenicmosoma paicum sp. nov.

The Fixator-A simple method for mounting of arthropod specimens and photography of complex structures in liquid.

Mounting and preparing arthropods in liquids for photography and further investigations is a challenging task and may lead to unsatisfactory results and, in the worst case, to damage to specimens. A new method is presented here, which allows the fixation of specimens of different sizes under various degrees of pressure. The method is illustrated by three case studies from different groups of insects and arachnids.
