Chelostoma mocsaryi, Schletterer, 1899

Chelostoma mocsaryi View in CoL species group

The four representatives of the Chelostoma mocsaryi species group are characterised in both sexes by the basal area of the propodeum, which is impressed, crossed by rather coarse longitudinal carinae and bordered posteriorly by a raised and polished to imperceivably shagreened transverse ridge ( Fig. 55 View FIGURES 49–58 ). Additional characters of the females are the medially flat base of the labrum, the absence of a small triangular incision at the apical margin of the labrum ( Fig. 52 View FIGURES 49–58 ) and the length of the basal area of the propodeum, which is as long as to shorter than the metanotum ( Fig. 55 View FIGURES 49–58 ). Additional characters of the males are two small tubercles or cone- to tooth-shaped projections on the hypostomal area arising laterally to the hypostomal carinae ( Fig. 54 View FIGURES 49–58 , 60 View FIGURES 59–65 , 70 View FIGURES 66–73 ), two short and rearwards projecting teeth on tergum 7 below the two upper teeth ( Fig. 56 View FIGURES 49–58 , 71 View FIGURES 66–73 ), and a well delimited polished to more or less shagreened, impunctate, hairless and sometimes slightly concave zone along the lower margin of the compound eye ( Fig. 61 View FIGURES 59–65 ). Chelostoma mocsary and probably also the three other species are oligolectic on Ornithogalum ( Asparagaceae ).
