South Eastern Australia

Organically preserved Cainozoic leaf fossils previously referred to Agathis are re-examined, and in all cases their affinity with that genus is confirmed. Previously undescribed organically preserved leaf fossils from several Cainozoic sites in south-eastern Australia are compared with Agathis and Wollemia and two new species of Agathis are described. Intraspecific variation in leaf cuticle morphology is examined in extant A. macrophylla in particular, and is found to be much higher than previously recorded. This makes assignment of fossil Agathis leaves to species difficult, especially when only leaf fragments are available. The new fossils extend the record of organically preserved Agathis macro-remains back to the Late Paleocene, but do not significantly extend the known spatial distribution.

Two New Species

During a survey conducted during 2013–2017, five known and two new species of Nothotylenchus Thorne, 1941 were collected from the southern provinces of Iran. N. brzeskii n. sp. is characterised by a body length of 774–922 µm, lateral fields with four incisures, delicate, short stylet (7–8 µm) with small rounded knobs, pyriform, offset or slightly overlapping basal pharyngeal bulb, posterior vulva position (V = 83.4–84.4), short PUS (5–10 µm), spicules 20.5–23 µm long, and thick tail with rounded to dull terminus. N. siddiqi n. sp. is characterised by a body length of 573–645 µm, six to nine incisures in lateral fields, delicate, short stylet (6.5–7.5 µm) with rounded knobs, pyriform or slightly elongate and offset basal pharyngeal bulb, V = 79.3–81.0, PUS = 26.5–40 µm, short spicules = 14.5–16.5 µm, and tail with rounded terminus. Morphometric data of the studied species are presented and intraspecific variation of their morphometrics and morphological characters is discussed. The list of world Nothotylenchus species is updated, and a dichotomous identification key and an updated tabular compendium for 41 valid species are provided.

Males And Females

Two new species in the tube-web spider genus Ariadna Audouin, 1826 (Segestriidae Simon, 1893) are described from South Australia based on morphological features of both males and females. Ariadnaclavatasp. n. and Ariadnatangarasp. n. are widespread and sympatric on eastern Kangaroo Island, where they are found beneath bark, in borer holes in dead wood, and in short burrows under rocks. They have also been found in south-eastern mainland South Australia and bring the total number of described Australian Ariadna to 13 species. We showcase intraspecific variation in both species based on a significant number of specimens, including substantial size variation in females and variations in patterns of leg spination. For male Ariadna, we also establish the previously unknown functions of apophyses and spines on the metatarsi and tibiae on the first legs, which are used during mating to clasp the female.

The current work presents the description of two Brazilian new species of the subgenus Endecous (Notendecous) Gorochov, 2014 recorded for the states of Rio Grande do Norte and Bahia, Northeastern Brazil. The morphology of phallic complex was used as main criterion for distinguishing the two species. Furthermore, aspects on the natural history, intraspecific variation and a pictorial key are presented considering the species known for this subgenus.

Abstract—A synopsis of Dicliptera (Acanthaceae) for Brazil is presented. Six species are recognized: Dicliptera ciliaris, D. sexangularis, and D. squarrosa, widely distributed in South America; D. purpurascens, which ranges from the North Region of Brazil (in the state of Acre) to eastern Bolivia; D. gracilirama, a new species from the Atlantic Forest of northeastern Brazil; and D. granchaquenha, a new species recorded in dry and semideciduous forests in Bolivia and western Brazil, in the state of Mato Grosso do Sul. Furthermore, we propose new synonyms and designate lectotypes for eleven names. An identification key to the six accepted Dicliptera species in Brazil is provided.
