REDESCRIPTION OF THE PUPA OF PARYPHOCONUSOLIVEIRAI LANE (DIPTERA: CERATOPOGONIDAE)FROM BRAZIL1María M. Ronderos,2 Gustavo R. Spinelli,2 and Daiane Silveira Carrasco3ABSTRACT: The pupa of Paryphoconus oliveirai Lane is described from a specimen collected froma sandy bottom of a shallow human disturbed stream near Manaus, Brazil. The pupa of P. oliveirai iscompared with previous descriptions of the pupa of this species and with the pupae of its congeners,P. flavidus (Johannsen), and P. mayeri Wirth.KEY WORDS: Paryphoconus oliveirai, predaceous midge, pupa, Diptera, Ceratopogonidae,Manaus, BrazilThe predaceous midge genus Paryphoconus Enderlein is exclusively Neotrop-ical, and includes medium-sized to large midges (female wing lengths 1.5-7.0mm). Presently there are 40 species in this genus (Borkent and Spinelli, 2000),and Spinelli and Wirth (1984) provided a key to females of 38 of these. Thepupae of only three species have been previously described: P. flavidus (Johann-sen) (as P. lanei) and P. mayeri Wirth by Mayer (1959), and P. oliveirai Lane byWirth and Ratanaworabhan (1972). These prior pupal descriptions are very briefand incomplete, and it is almost impossible from them to determine the most rel-evant structures at even the generic level.During recent field sampling by DSC in the vicinity of Manaus, Brazil, onepupa of P. oliveirai was collected. The purpose of this paper is to redescribe andillustrate the pupa of this species, the first detailed description of a pupa ofParyphoconus sp.METHODSA single live pupa of P. oliveirai was collected from the sandy bottom of ashallow human disturbed stream (Fig. 1). The sandy sediment was collected withan aquatic net (Fig. 2) and transported to the laboratory with water from the nat-ural environment in a 5 liter plastic container. The pupa was lab reared and theadult eventually emerged and its exoskeleton allowed to harden before preserva-tion in 70% ethanol. This adult female and its pupal exuvia was slide-mounted in Canada balsamfollowing the technique of Borkent (2000), and examined and measured with abinocular compound microscope. Illustrations were made with pen and ink usingan attached camera lucida. This specimen is deposited in the collection of Invertebrates, InstitutoNacional de Pesquisas da Amazônia, Manaus, Brazil (INPA).

The adult female keys out to P. oliveirai in couplet 26 in the key bySpinelli and Wirth (1984). It was also compared with one female examined byWirth and Ratanaworabhan (1972) as P. oliveirai, who briefly described the pupaof this species based on material from the same locality and date. However, theirpupa differs from the pupa described herein in having 13 spiracles on the respi-ratory horn and in the shape of the caudal segment, has subparallel lateral mar-gins and the posterolateral processes are nearly straight, not divergent.Mayer (1959) described the pupa of P. mayeri, which is much smaller (length4.3 mm) than our pupa of P. oliveirai. Also, despite the terminology of thecephalothoracic tubercles is different from the one used in this redescription,Mayer mentioned one ad and three dl tubercles (as a spine devoid of seta and 3setae at the base of the respiratory organ, respectively) and only one vm seta,which are the most important differences with respect to the pupa of P. oliveirai.Mayer (1959) also described the pupa of P. flavidus (as P. lanei), and stated thatit is very similar to the one of P. mayeri except for the vm which is representedby a short seta.ACKNOWLEDGMENTSWe would like to acknowledge Dr. William L.

New data on Asyndetus (Diptera: Dolichopodidae) from China, with description of a new species

WOS: 000247359800008The funnel-web spider, Agelena gracilens Koch C. L., 1841 is widely distributed throughout Middle Europe, Mediterranean countries, and Middle Asia. The aim of this study is to describe the functional morphology of the venom apparatus in A. gracilens using scanning electron microscopy. The organization of the venom apparatus of A. gracilens follows the general structure of the venom apparatus ofother spiders. The venom apparatus is situated anteriorly in the prosoma and it is composed of a pair of chelicerae and venom glands. Each chelicera consists of a Stout basal and a movable apical (fang) segments. The fang rests in a furrow on the basal segment and it narrows apically. There are parallel fine grooves on the surface ofthe fang. To eject the venom, a venom pore is located on the subterminal part of the fang. The venom glands of A. gracilens are of equal size and tubular. Each gland is Surrounded by a bulky muscular layer. Also, neurons innervate the surface of the venom gland by SEM
