Morphological Characteristics of Male Genitalia in Some Species of the Genus Eurytoma (Eurytomidae, Hymenoptera)
Based on the analysis of morphological characteristics of related species of the genus Eurytoma, several groups of cryptic species poorly distinguishing by external morphology, but clearly confined to certain hosts are shown to have morphological differences of male genitalia that are highly species-specific and can be useful for identification of cryptic species of the genus Eurytoma (E. rosae Nees, E. strigifrons Thomson, and E. jaceae Mayr species complexes).
Chromosome Y Isodicentrics in two Cases with Ambiguous genitalia and Features of Turner Syndrome
Karyotype investigations using classical cytogenetics, fluorescence in situ hybridization (FISH) and polymerase chain reaction (PCR) techniques were used for the characterization of Y chromosome structural anomalies found in two patients with ambiguous genitalia and features of Turner syndrome. Both exhibited mosaic karyotypes of peripheral blood lymphocytes. The karyotype was 45, X/ 46, X, idic(Y)(p11.3).ish idic(Y) (wcpY+, DXYS130++,SRY++,DYZ3++,DYZ1++, DYS224++) in one case, and the karyotype was 45, X/46, X, idic(Y) (q11).ish idic(Y)(SRY++, RP11-140H23-) in the other case. Derivative Y chromosomes were different in shape and size and positive for the SRY gene, a common underlying element of ambiguous genitalia phenotypes. These results add new information concerning the role of Y chromosome structural abnormalities in sex determination pathway perturbation which are poorly understood, and highlight the importance of the sex chromosomes integrity for a normal sex phenotype development.

The Old World genus Thysanarthria Orchymont, 1926 is reviewed taxonomically and compared to the related genus Chaetarthria Stephens, 1835. Chaetarthria is considered to consist of three groups differing in the morphology of male genitalia and surrounding sclerites: (1) large Old World Chaetarthria which seems to stand apart of the remaining groups, and (2) European Chaetarthria plus (3) American Chaetarthria which both share the male sternite 8 with a long median projection with Thysanarthria. The reduced mesal part of male sternite 9 is shared by European Chaetarthria and Thysanarthria, supporting their close relationship proposed by previous molecular analyses. Sixteen species are recognized within Thysanarthria which differ in the details of the morphology of the aedeagus illustrated for all species. Seven species are described as new: T. bifida sp. nov. (Thailand), T. cardamona sp. nov. (India: Kerala), T. chui sp. nov. (Taiwan), T. persica sp. nov. (southern Iran), T. saurahana sp. nov. (Nepal), T. trifida (Laos), and T. wadicola sp. nov. (Oman). New records are provided for T. ceylonensis Hebauer, 2001 (new to India: Madhya Pradesh), T. championi (Knisch, 1924) (new to Afghanistan, India: Arunachal Pradesh, China: Yunnan, and Myanmar), T. madurensis Hebauer, 2001 (new to Nepal and India: Kerala), and T. siamensis Hebauer, 2001 (new to India: Uttarkhand, Nepal and Laos). Chaetarthriomorphus sulcatus Chiesa, 1967 is revealed as a junior synonym of Chaetarthria championi Knisch, 1924, and lectotypes are designated for both these taxa. An undescribed species of the American group of Chaetarthria is recorded from Saudi Arabia either as an accidental introduction or due to mislabeling; the species is illustrated but not described.

Brachycerus socotranus sp. nov., endemic to Socotra Island, is described from the three specimens collected by the Czech expeditions to Socotra in 2000–2012. The new species is characterized by prominent horn-like tubercles at the base of the rostrum, intact medial groove of pronotum with strongly prominent longitudinal carina and sexual dimorphism in the form of the apical part of the elytra.
