Procheiridium judsoni n. gen. et n. sp. is described from Burmese cretaceous amber. This species represents the earliest record of the pseudoscorpion subfamily Pycnocheiridiinae and the first fossil taxon of the subfamily to be recorded. The phylogenetic position of the new genus in the superfamily Cheiridioidea is discussed.

Procaeculus coineaui sp. nov. from Cretaceous Burmese amber is described and its phylogenetic position discussed. This fossil taxon is the first caeculid mite known from Burmese amber and constitutes the earliest record of the family. The genus Procaeculus is redefined to include the new fossil species and internal relationships between genera of the family are discussed based on a phylogenetic hypothesis.

Fossil Genus

A new fossil genus of Bibionidae (Diptera: Bibionomorpha), Burmahesperinus gen. nov., from the mid-Cretaceous Burmese amber, is described and illustrated (type species Burmahesperinus antennatus sp. nov., the other two species included are B. conicus sp. nov. and B. pedicellatus sp. nov.). The new genus is tentatively placed in a new subfamily, Burmahesperininae subfam. nov. of the family Bibionidae. Its possible phylogenetic position is briefly discussed. The new genus, as well as the subfamily, possesses the wing venation similar to the recent genus Hesperinus Walker, 1848, in combination with Brachycera-like modification of both the male and female antenna and the overall habitus typical of fungus gnats (Sciaroidea).

Generic boundaries of the South American species Panicum longipedicellatum Swallen are explored and compared with allied genera of the tribe Paniceae. On the basis of morphological, anatomical, and molecular characters a new genus, Cnidochloa Zuloaga, is proposed. The phylogenetic position of the new genus within the Paniceae is evaluated.

Evolutionary Level

The name Pseudoditrichum mirabile Steere et Iwatsuki is proposed for a minute moss with leafy stem 1-3 mm high and seta 6 mm long; it was collected on calcareous silt near the Sloan River, Great Bear Lake, Northwest Territories, only a few miles south of the Arctic Circle. The gametophytic characters agree well with those of the Ditrichaceae, a relatively primitive family, but the peristome is clearly double, with the inner and outer teeth opposite, which thereby indicates a much more advanced phylogenetic position, perhaps at the evolutionary level of the Funariaceae. As the combination of gametophytic and sporophytic characteristics exhibited by this moss does not occur in any existing family of mosses, it is therefore deemed necessary to create the new family Pseudoditrichaceae for the new genus and species described here.

Two New Species

A new genus, Graziasternum gen. nov., with two new species, Graziasternum graziae sp. nov. and Graziasternum joceliae sp. nov. are described. According to external thoracic and genital structures, this new genus is considered to be the closest extant relative known to the genus Placosternum Amyot & Serville. Discussion of its possible phylogenetic position based on structure comparison, with the discussion on the importance of the characteristics of the thoracic sterna, the genital structures with other genera or groups of genera that share similar structures is given. Additionally, the two new species are keyed and illustrated.

Undescribed Species

New Caledonia has an endemic opiliofauna with two named species of Triaenonychidae, 17 Troglosironidae and eight Zalmoxidae. The recent finding of Neopilionidae on Grande Terre was thus surprising, and required the formal description of a new genus, which we undertake here. Martensopsalis gen. nov. is characterized by a small unsclerotized body with a unique palp with a pointed basal apophysis on the ventral side of the femur and with a distal apophysis on the prolateral side of the patella. The distinct external morphology, simple penis and unique phylogenetic position justify the erection of the new genus with Martensopsalis dogny spec. nov. as its type species. In addition to the type locality we report several other localities of putative congeneric, yet undescribed species.

A novel actinobacterium, designated strain C4-31T, was isolated from soil collected from a cave. Cells were aerobic, Gram-reaction-positive, oxidase-negative, catalase-positive and non-motile cocci. Comparison of 16S rRNA gene sequences showed that the organism occupied a distinct phylogenetic position within the suborder Frankineae, with sequence similarity values of less than 93.2 % to members of this suborder. The diagnostic diamino acid in the cell-wall peptidoglycan was meso-diaminopimelic acid. The major menaquinone was MK-9(H4). The polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol, phosphatidylinositol mannoside, an unknown aminophospholipid and an unknown phospholipid. The major fatty acids were iso-C16 : 0, C17 : 1ω6c and C16 : 0. The G+C content of the DNA was 62.8 mol%. On the basis of morphological and chemotaxonomic data as well as phylogenetic evidence, strain C4-31T ( = KCTC 39556T = DSM 100065T) is considered to represent the type strain of a novel species of a new genus in the suborder Frankineae, for which the name Antricoccus suffuscus gen. nov., sp. nov. is proposed.

The Relationship

A new genus and species of the lacewing family Psychopsidae, Electropsychops handlirschi gen. et sp. nov., is described based on a well preserved male specimen from the mid-Cretaceous amber of Myanmar. The new genus possesses a number of diagnostic characters of Psychopsidae, i.e., the lack of a forewing median nygma, the presence of a vena triplica, and the straight and barely forked RA. However, it also exhibits some remarkable characters that are present in Osmylopsychopidae, such as the distally narrowed forewing costal space and the sigmoid MA stem in the hind wing. The relationship between Psychopsidae and Osmylopsychopidae is briefly discussed.
