A New Species

The oribatid mite genus Oribatella includes over 100 named species, none of which shows distinct sexual dimorphism in the octotaxic system of dermal glands. We propose a new species of this genus, Oribatella canadensis sp, nov., collected from dry soil habitats in western Canada, that shows distinct dimorphism in these dermal glands, the first record of this dimorphism in the Oribatelloidea. The posterior pair of glands in males, but not females, is enlarged and associated with a shallow, medial pit-tubercle complex, and is generally similar to convergent dimorphisms in some genera of Mochlozetidae (Oripodoidea), Mycobatidae (Ceratozetoidea) and Galumnidae (Galumnoidea). We describe this species based on adult and nymphal stages, and expand the diagnosis of the genus to accommodate the newly described immatures. We review the expression of sexual dimorphism in brachypyline oribatid mites and discuss its association with periodically dry habitats.

A New Species

A new species Neoribates isabelaensis sp. nov. showing an interesting sexual dimorphism is described from bamboo litter on Luzon Island in the Philippines. This species is unique among other species of Neoribates in the structure of the posterior part of notogaster in males, which has a large round concavity bearing a pair of large sacculi S3. The specific function of this structure is not yet known, but the found sexual dimorphism is presumably involved in pheromonal communication allowing rapid sperm transfer. This is the fourth Neoribates species displaying sexually dimorphic characters. Additionally, Neoribates isabelaensis sp. nov. differs from the morphologically most similar species, Neoribates barbatus Hammer, 1968, by its smaller body size, pointed rostrum, long and setiform bothridial setae and the localization of notogastral setae h1 and h2, which insert close to each other. Further, we discussed all cases of sexual dimorphism in the family Parakalummidae as well as other related groups of Oripodoidea, and the possible function of these modifications.

AbstractThe oribatid mite genus Zachvatkinibates, found in littoral, forest canopy, and forest litter habitats, includes some species showing distinct sexual dimorphism in the octotaxic system of dermal glands, and others lacking this dimorphism. Three new species in this genus are described on the basis of adults, each of which shows species-specific sexual dimorphism: Z. nortonisp. nov. and Z. schatzisp. nov. from beach debris in British Columbia, Canada, and Z. shaldybinaesp. nov. from the littoral in eastern and northeastern Canada. We discuss the association of sexual dimorphism with the littoral habitat of species in this genus and, more generally, the expression of sexually dimorphic porose areas in Ceratozetoidea. We revise the diagnosis for the genus Zachvatkinibates and present a revised key for adults of Zachvatkinibates species of North America north of Mexico.

A study of the holotype of Pinnotheres hemphilli Rathbun, 1918, revealed it is an early post-hard female, not a male, of Fabia Dana, 1851. The morphology of Pinnotheres emiliai Melo, 1971 (based on a male specimen) and Fabia insularis Melo, 1971 (based on a female specimen) confirm earlier hypothesis that they belong to a sexually dimorphic species that should be known as F. emiliai (Melo, 1971). The redescription of the holotype of Fabia felderi Gore, 1986, supports its generic assignment and its relationship with F. emiliai. The implication of sexual dimorphism and intersexes in the taxon-omy of Fabia is discussed.

A New Species

Corotoca Schiødte, 1853 is a Neotropical genus of termitophiles beetles, with five species, and its description marks the first record of insects associated with termites. A new species, Corotoca fontesi sp. nov., from Brazil, is described and illustrated, and a taxonomical problem regarding to the identification and nomenclatural status of two species, Corotoca phylo Schiødte, 1853 and Corotoca seeversi Fontes, 1977, is solved. Therefore, Corotoca seeversi is proposed as a new junior synonym of C. phylo, and the material identified as C. phylo housed in the Museum of Zoology of the University of São Paulo, Brazil (MZUSP) is recognized as a new species, Corotoca fontesi sp. nov. New morphological and sexual dimorphism data in the species, and solution of some messy informations about the genus present in the literature are also present.

Catinia aiso sp. n. was found in association with the mud shrimp, Axianassa australis Rodrigues & Shimizu, 1992 collected in the intertidal zone of Araçá Beach, state of São Paulo, Brazil (23°48’50’’S, 45°23’48’’W). The new species shares with Catinia plana Bocquet & Stock, 1957 the structure of the oral appendages, the setal formula of the swimming legs, the robust pedunculate sucker on the antenna, and the absence of the maxilliped in adult females. However, the two species can be separated by the rostrum shape, the presence or absence of an inner coxal seta on leg 4, and the structure of leg 5 in both sexes. Catinia aiso also differs from C. plana in the depressed ovoid body shape, the ornamentation of the maxilla in the female and in the modified claw of the maxilliped of the male. The sexual dimorphism expressed in the armature of the antennule and the endopodal segments of the swimming legs in C. plana, is absent in C. aiso. This is the first record of Catinia since the genus was established on the basis of material from the Baie de Morgat, France, in 1957.

We describe a new species of rock gecko of the genus Cnemaspis from Java, Indonesia, representing the first record of the genus for this Island. The new species was collected from the southern slopes of Gunung Muria, a dormant volcano in Central Java. The new species is easily distinguished from all congeners by having a maximum SVL of 58.1 mm in males and 56.9 mm in females; a pair of sharp conical tubercle clusters on the occiput; a warty bridge on the nuchal loop, extending from the upper tympanum and curving to the nape; dorsal tubercles not linearly arranged; 18–20 paravertebral tubercles; postmentals separated by one scale; gular, pectoral and abdominal scales, ventral scales of fore- and hindlimbs, and subcaudal scales keeled; no tubercles on lower flank; precloacal and femoral pores absent; enlarged submetacarpal scales present on the first digit of the manus; 38–40 ventral scales; 31–35 lamellae under fourth toe; two postcloacal tubercles on each side; enlarged median subcaudal scales row present; caudal tubercles encircling tail; and a sexually dimorphic ventral color pattern, with males having a yellow belly and females white and the ventral surface of the tail in males yellow proximally changing to white at mid-length, whereas in females, alternating black and white rings completely encircle the tail, which is black distally.
