Ten new species of Broun, 1886 from New Guinea are described: , , , , , , , , , and . All of them together with five already described species are united into the newly defined -group (with -subgroup), a polyphyletic complex of related species with lateral setation on the median lobe. In the light of newly available material, all previously described species of the -group are considered to belong to a single species, (Balke, 1998), which is now placed into the -group, and three new synonyms are therefore proposed: (Balke, 2001) ., (Balke, 1998) ., and (Balke, 1998) . (Balke, 1998) . is a junior synonym of (Balke, 1998). Redescription of (Balfour-Browne, 1939) is provided based on its type material. An identification key to all known species of the group is provided, and important diagnostic characters are illustrated. Data on the species distribution are given, showing that whilst most species are local endemics, is extremely widely distributed.

Seven new species of the genus Broun, 1886 are described from three different mountain ranges of New Guinea: , , , and from the Foja Mountains; from the Cyclops Mountains; and from Wano Land. All of them are placed into the group based on the structure of their male genitalia. The species are characteristic dytiscid elements of the fauna of northern cost and the western part of central orogen of New Guinea.

Objective: Continuous spikes and waves during sleep (CSWS) is an epileptic encephalopathy characterized by generalised epileptiform activity and neurocognitive dysfunction. Causes and outcome are diverse and treatment is mainly empirical.
Methods: Retrospective descriptive analysis of clinical and EEG data of children with CSWS diagnosed between 1998 and 2018 at the University Hospital Heidelberg.

Six new species of New Guinea Broun, 1886 are described in this paper: , , , , , and . Although different morphologically, together with (Balke, 1998), (Balke & Hendrich, 2001), and Shaverdo, Panjaitan & Balke, 2016, they are found to form a monophyletic clade and be closely related to representatives of the -group, based on preliminary analysis of sequence data. An identification key to the species is provided, and important diagnostic characters are illustrated.
