The European species of Chalarus Walker, 1834 revisited (Diptera: Pipunculidae) Author Kehlmaier, Christian Author Assmann, Thorsten text Zootaxa 2008 1936 1 39 journal article 10.5281/zenodo.184950 b652166d-e8aa-4d19-89b3-74ce8634d436 1175-5326 184950 Chalarus exiguus ( Haliday, 1833 ) Pipunculus exiguus Haliday, 1833 : 162 Chalarus konishii Morakote , in Morakote & Hirashima, 1990 : 169 . Synonymy: Jervis (1992: 290) . Diagnosis: Males could not be recorded in this study. See Jervis (1992) for a characterisation. Female with frontal facets greatly enlarged (J92 Fig. 2 B); frons very narrow, at narrowest point 1.0 times diameter of largest frontal facet; flagellum dark brown; legs dark brown but base of femora and area around femoral-tibial joints may be somewhat paler; pulvilli of all legs of same size, shorter than distitarsus; hairs on femora dark brown but pvsr of mid femur light brown; hairs on thorax and abdomen dark brown; hind femur with apical hairs of pdsr extending as far as apex; abdominal tergites dark brown; ovipositor as in Figs 53 & 56 . See Table 1 for coxI and ITS2 barcode sequence accession numbers. Annotations: The taxon was originally described from the female holotype . No male specimens could be associated with the two females sequenced in this study, but following Jervis (1992) , who reared males and females from Alnetoidia alneti taken on the same day and locality, adult males are morphologically indistinguishable from C. holosericeus . However, Jervis (1992) distinguishes males of C. exiguus and C. holosericeus on the basis of pupal characters.
