Polypedilum digitifer Townes andPolypedilum griseopunctatum (Malloch) (Diptera,Chironomidae): Redescription of adult males with a description and separation of the immature stages

Polypedilum (Tripodura) digitifer Townes andPolypedilum (Tripodura) griseopunctatum (Malloch) are morphologically similar species of Chironomidae. Using associated material from New York State, the adult males for both species are redescribed (adding previously ignored characters) and the mature larva and pupa are thoroughly described for the first time. Traits for distinguishing these species from each other and possibly from other Nearctic species ofPolypedilum (Tripodura) are provided.     

Two New Tanytarsus Species (Diptera: Chironomidae) from Brazil,with Reduced Median Volsella

The male adults Tanytarsus monospinosus sp. n. and Tanytarsus tumultuarius sp. n. from Brazil are described as new to science, and the species Tanytarsus abnormis Lehmann is transferred to Neostempellina Reiss. The species share the reduction of the median volsella, a genital feature well developed amongst most species of Tanytarsini. There are no obvious close relatives amongst previously described Tanytarsus species, and a thorough phylogenetic analysis including the immature stages will be necessary. However, because there are large differences between these two new species in most morphological characters, it can be assumed that they are not closely related, and the loss of the median volsella thus is unlikely to be a synapomorphy.     

A new species of Dicrotendipes (Diptera: Chironomidae) from Costa Rica

The adult male of Dicrotendipes baru is described from the Dominical area of southwestern Costa Rica. The species is characterized by its elongate club-like superior volsella. This species represents the third member of the genus known from Costa Rica.

Identification of instars and species in some larval Polypedilum (Polypedilum) (Diptera: Chironomidae)

Instars II and III of Polypedilum aviceps Townes, Polypedilum convictum (Walker), and Polypedilum illinoense (Malloch) can be identified to species by associating them with instar IV because key taxonomic characters remain relatively unchanged from instar to instar. Instars I cannot be identified to species or genus unless they are associated with older, identifiable larvae reared from the same egg masses. No single character evaluated on slide material can be used to clearly separate instars in all three species. Larvae of P. aviceps can be separated into instars based on any four of seven characters; P. convictum by either of two characters; and, P. illinoense by a combination of two characters. Changes in structures of instars II, III, and IV are described for all three species. Growth ratios for some structures are compared and discussed with regard to Dyar's Rule.

Morphological evidence for the evolutionary origin of Astigmata (Acari: Acariformes)

A century ago, Antonio Berlese first discussed the close phylogenetic relationship between the large mite groups Oribatida and Astigmata. Since then, information having phylogenetic value has greatly increased and the paradigms within which we interpret it have changed. Herein I refine the general hypothesis that Astigmata originated within oribatid mites and suggest Malaconothridae as a possible sister group. Among the 14 apomorphies used to support the origin of Astigmata within oribatid mites are possession of lateral opisthosomal glands, regression of hysterosomal setal pair f1, paired prelarval denticles, partially internalized chelicerae with incomplete adaxial walls, an atelobasic rutellum, pretarsal condylophores that articulate posteriorly with the tarsus, a dorsally fused palp tibia and tarsus and transdehiscent ecdysis. A further 13 apomorphies support the origin of Astigmata at some level within Malaconothroidea. These include absence of an oblique labiogenal articulation, presence of a distal rutellar lamella, shortening of the palp tarsus, larval regression of hysterosomal seta f2, loss of the bothridial seta in all instars, and several losses and modifications of leg setae. The hypothesis brings to light evolutionary questions that were previously obscured by incorrect or inappropriate classifications. The nomenclatural problems that arise from it are best solved by considering Astigmata as a subgroup within Oribatida.
