Revision of the genus Allometopon Kertész (Diptera: Clusiidae) Author Owen Lonsdale text Zootaxa 2016 4106 1 1 127 journal article 37266 10.11646/zootaxa.4106.1.1 db12a9b2-ae53-4790-bdba-6a5799762618 1175-5326 258766 A5ADF236-5219-4014-9DC4-C43F981DD1A4 Allometopon flavum Lamb, 1914 Figs 298–301 Allometopon flavum Lamb, 1914 : 311 . Melander & Argo 1924 : 6 [synonymy]; Frey 1960 : 26 [catalogue, World]; Cogan 1980 : 636 [catalogue, Afrotropics]. Description [mostly from Lamb (1914) ]. General : ( Figs 298–301 ) Holotype in very poor condition; extensively damaged with only thorax, right mid leg and abdomen remaining on minuten; one wing on card. Body length 3.5mm . Arista pubescent. First flagellomere small, circular. M1+2 ratio 2.4. Female unknown. Chaetotaxy : Four fronto-orbital setae, slightly decreasing in length anteriorly. Ocellar and postvertical setae small. Interfrontal seta “comparatively stout”. Anterior dorsocentral seta appearing to be more than half length of posterior dorsocentral; slightly enlarged seta in front of anterior dorsocentral; dorsocentral setae displaced posteriorly. Two lateral scutellar setae (positioning difficult to ascertain). Colour : Setae light brown. Entirely yellow with first flagellomere black, arista brown; ocellar tubercle presumably brown. Lamb (1914) notes three brown stripes on thorax, but these may be an artifact created by attachment of underlying muscles; also noted are brownish tarsi, which also appear to be yellow in the examined photo. Male terminalia : Not dissected. Distribution: Seychelles . Holotype : SEYCHELLES . Praslin: Côtes d’Or Estate, 1908 Seychelles Exp., J.S. Gardiner, 1914-537, “ HOLOTYPE Allometopon flavum Lamb , det. J.E. Chainey, 1984” ( 1♂ , BMNH ). [Photos examined] Comments: Allometopon flavum is the only Allometopon known from Seychelles , and still represented solely by the male holotype . While the description and available photographs of the poorly preserved type cannot provide a through description of this species, it appears to be allied to the A. palpale group, specifically, with A. acum ( Fig. 1 ) and A . hybos ( Fig. 120 ), which are yellow species with similarly pale setae and a black first flagellomere. It is nearly inseparable from A. hybos (southeast Asia), and the examination of new material is required to better differentiate the two and describe the male genitalia.
