Calliopum splendidum

Abstract

<i>Calliopum splendidum</i> <p>Egg (Figs 41–43). Length 0.65–0.74 mm Chorion slightly differentiated in dorsal and ventral side. Dorsal side with more developed longitudinal ridges and regular longitudinal channels.</p> <p>First larval instar (Figs 51, 52, 55–60). Length 1.12–2.16 mm. Length of cephaloskeleton (Fig. 113) 0.21–0.22 mm.</p> <p>Second larval instar (Figs 65, 66, 69–74). Length 2.14–3.58 mm. Length of cephaloskeleton (Fig. 114) 0.37–0.39 mm.</p> <p> Third larval instar (Figs 79, 101–106). Length 3.53–4.30 mm. Anterior spiracles with 7 papillae, the two marginal papillae are curved back (Fig 80). Integument of abdominal segments and anal division villous, small smooth areas are retained behind dorsal tubercules in first four segments and partly between segment borders. Extensive smooth areas are on the ventral side behind anterior creeping welt. The only species of <i>Calliopum</i> with comb spines on the posterior half of the first thoracic segment. Length of cephaloskeleton (Fig. 115) 0.61–0.63 mm.</p> <p> Puparium (Fig. 121). Length 3.61–3.89 mm. Indistinguishable from <i>C. simillimum</i>. Smaller size can be result of unfavourable rearing conditions, as adult flies are comparably large to <i>C</i>. <i>simillimum</i>.</p>Published as part of <i>Semelbauer, Marek & Kozánek, Milan, 2012, Morphology of preimaginal stages of Lauxania and Calliopum (Diptera: Lauxaniidae), pp. 1-28 in Zootaxa 3346</i> on pages 24-25, DOI: <a href="http://zenodo.org/record/214261">10.5281/zenodo.214261</a&gt
