First fossil species of family Hyidae (Arachnida: Pseudoscorpiones) confirms 99 million years of ecological stasis in a Gondwanan lineage.

Burmese amber preserves a diverse assemblage of Cretaceous arachnids, and among pseudoscorpions (Arachnida: Pseudoscorpiones), ten species in five families have already been named. Here, we describe a new fossil species from Burmese amber in the pseudoscorpion family Hyidae, providing detailed measurements, photographs and 3D-models from synchrotron scanning. Based on morphology, the new fossil, Hya fynni sp. nov. is placed in the genus Hya, and is nearly identical to extant species in the genus, except for the position of trichobothrium est on the pedipalpal chela, thereby indicating extreme morphological stasis in this invertebrate lineage over the last 99 million years. Hya fynni represents the first described fossil species in Hyidae, and the third described Burmese fossil in the superfamily Neobisioidea. It also joins the garypinid, Amblyolpium burmiticum, in representing the oldest fossil records for extant pseudoscorpion genera. Considering proposed divergence dates, the newly described fossil species bolsters a Gondwanan origin for Hyidae, and provides evidence for the "Late Jurassic Rifting" hypothesis for the Burma Terrane, in which this landmass rifted from Gondwana in the Late Jurassic and collided with Eurasia by the Cretaceous/Eocene. Like Hya species today, H. fynni likely inhabited humicolous microhabitats in tropical forests on the Burma Terrane, supporting ecological niche stasis for this family since the Mesozoic.

Forensic Evaluation of Refugees from Myanmar.

Forensic evaluators may have little experience and knowledge of the political context of Myanmar, the Burmese people, and the refugee crisis. Oppression of several ethnic minority groups has marked Burmese military rule of Myanmar for several decades. Protracted trauma exposure, both pre- and post-migration, among refugee populations increases the risk for mental health disorders, particularly depression, anxiety, alcohol abuse, and posttraumatic stress disorder. These experiences may result in anger and psychiatric manifestations that bring Burmese refugees in conflict with the law in their host country. Culture influences how mental distress is experienced and reported, and it can influence a forensic evaluator's assessment of psychological-legal matters, such as competency to stand trial and asylum evaluations. The salience of cultural competence becomes particularly pressing given the small number of those of Burmese background in the United States. Most evaluations will be performed by forensic mental health professionals who are not Burmese in ethnicity, nor familiar with Burmese culture. In this article, we provide a backdrop of the military suppression of ethnic minorities prior to discussing the integration of cultural matters in forensic assessments of competency to stand trial, competency for extradition, and asylum seekers in Burmese refugees.
