Comprehensive inventory of true flies (Diptera) at a tropical site

Estimations of tropical insect diversity generally suffer from lack of known groups or faunas against which extrapolations can be made, and have seriously underestimated the diversity of some taxa. Here we report the intensive inventory of a four-hectare tropical cloud forest in Costa Rica for one year, which yielded 4332 species of Diptera, providing the first verifiable basis for diversity of a major group of insects at a single site in the tropics. In total 73 families were present, all of which were studied to the species level, providing potentially complete coverage of all families of the order likely to be present at the site. Even so, extrapolations based on our data indicate that with further sampling, the actual total for the site could be closer to 8000 species. Efforts to completely sample a site, although resource-intensive and time-consuming, are needed to better ground estimations of world biodiversity based on limited sampling

Changes to the Fossil Record of Insects through Fifteen Years of Discovery

The first and last occurrences of hexapod families in the fossil record are compiled from publications up to end-2009. The major features of these data are compared with those of previous datasets (1993 and 1994). About a third of families (>400) are new to the fossil record since 1994, over half of the earlier, existing families have experienced changes in their known stratigraphic range and only about ten percent have unchanged ranges. Despite these significant additions to knowledge, the broad pattern of described richness through time remains similar, with described richness increasing steadily through geological history and a shift in dominant taxa, from Palaeoptera and Polyneoptera to Paraneoptera and Holometabola, after the Palaeozoic. However, after detrending, described richness is not well correlated with the earlier datasets, indicating significant changes in shorter-term patterns. There is reduced Palaeozoic richness, peaking at a different time, and a less pronounced Permian decline. A pronounced Triassic peak and decline is shown, and the plateau from the mid Early Cretaceous to the end of the period remains, albeit at substantially higher richness compared to earlier datasets. Origination and extinction rates are broadly similar to before, with a broad decline in both through time but episodic peaks, including end-Permian turnover. Origination more consistently exceeds extinction compared to previous datasets and exceptions are mainly in the Palaeozoic. These changes suggest that some inferences about causal mechanisms in insect macroevolution are likely to differ as well

Paramorganiella adventurosa Tonnoir 1929

<i>Paramorganiella adventurosa</i> Tonnoir 1929 <p>Tonnoir 1929: 606.</p> <p> <b>Remarks on identification.</b> We identified our specimens on the basis of the male description by Tonnoir (1929), which includes a figure of the unmistakable mouthparts (text fig. 5). It is important to note that the wing figures 14 and 15 in Tonnoir´s paper were mistakenly inverted, and the <i>Paramorganiella</i> wing is actually shown in fig. 14, not 15. We did not study the holotype of <i>P. adventurosa</i>, which according to Bugledich (1999) is allocated in the Australian National Insect Collection, Canberra.</p> <p> <b>Male redescription. Head.</b> Fourth flagellomere 1.8 times as long as wide. Clypeus elongate ovate, on basal half convex, with large setae, on distal half clearly concave, basket-shaped, with sparse fine setae (Fig. 2A). Surface of stipes with microtrichia arranged in lines, lateral setae; stipites fused anteriorly, forming Ushape, with sclerotized longitudinal axis. Lacinia, if correctly identified, present as sclerotized rib between stipes and base of second maxillary palpus segment (Fig. 4C). Palpus 5-segmented, segments 1–4 more or less strongly modified (Fig. 2C–E, 4C). Segment 1 fused medially with proboscis, large setae dorsally, subtriangular process apically to receive segment 2. Segment 2 swollen, largest of all, short setae dorsomedially, 6–7 sensilla coeloconica arranged in line ventromedially. Segment 3 short, inserted subapically on segment 2, 2 short stiff setae medially and long sclerotized process dorsally which bears 4–5 setulae apically, otherwise bare, without specialized sensilla. Segment 4 with 6–7 long stiff setae medially, 2 sclerotized processes, dorsal process broad, with 3–4 large setae, otherwise bare, margin occasionally irregularly serrate, lateral process narrow, dagger-shaped, bare. Segment 5 elongate, slightly club-shaped, 10– 12 stiff setae on apical half. Prementum very large, bilobed, lobes separate medially, densely microtrichose (Fig. 2B). Premental apodemes touching each other medially, forming X-shape. Basal segment of labellum asetose, apical segment setose (Fig. 4C).</p> <p> <b>Wing</b> (Fig. 3). Length 2.3–2.8 mm. Slightly fumose in the distal region of R1 and R5. Halter whitish.</p> <p> <b>Legs.</b> Tarsomere 4 of fore leg with crest of 3–4 short stiff setae ventrolaterally, tarsomere 5 with 2 setae of same kind but shorter, both groups of setae together forming clamping apparatus when tarsomeres are folded (Fig. 3B).</p> <p> <b>Terminalia.</b> St 9 fused with gonocoxites, identifiable as sclerotized rib close to basal margin of gonocoxites (Fig. 4B). Tg 9 subrectangular, densely setose, apical margin slightly emarginate (Fig. 4B). Gonocoxites largely fused ventrally, on apical half separated by narrow cleft, short ventral and longer lateral setae, on apical margin 2 pairs of processes, lateral pair hook-like, medial pair short subtriangular (Fig. 4B). PostGA convoluted, fringed apically, with finger-like medial process tipped by one thick macroseta (Fig. 4A). AntGA very large, rounded (Fig. 4A). Gonostylus directed medially, slender, tapered towards apex, with a few short setae including 4 strong, stiff setae in line on ventral margin, and 2 subapical setulae (Fig. 4A). Parameres fused to form short tegmen with deeply notched apical margin, strongly sclerotized, parameral apodemes large, rounded (Fig. 4A). Hypoproct slightly shorter than cerci (Fig. 4B), separate apicomedially, with dense large microtrichia and a few apical setae. Cerci separate medially (Fig. 4B), dense microtrichia, setae of various sizes including several thick stiff setae pointing ventrally.</p> <p> <b>Female description. Head.</b> Antenna much shorter than in male, fourth flagellomere 1.4 times as long as wide. Clypeus convex (Fig. 3A). Lacinia style-like (Fig. 3A). Palpus segment 2 thicker than other segments, segment 3 without sensilla cochleariformis (Fig. 3A), which are usually present in Mycetophilidae (Søli 1997).</p> <p> <b>Thorax.</b> Shallower than in male. <b>Wing.</b> Length 2.8 mm. As the male (Fig. 3C).</p> <p> <b>Preabdomen.</b> St 4–7 with numerous short stiff blunt-tipped setae among ordinary setae. <b>Terminalia.</b> In accordance with the mycetophilid ground pattern (cf. Søli 1997: fig. 37B). Disticercus somewhat shorter than basicercus.</p> <p> <b>Specimens studied.</b> <i>Slide mounted:</i> Australia, Tasmania, Warra, Mt Weld, N. Doran & R.
