Distribution.
Restricted to the Island of Crete, Greece.
Description.
Female: highly similar to southern populations of the nominal subspecies, differs as follows: apical tergal fringes snow white (Figs 35 View Figures 32–39 , 44 View Figures 40–45 ), as in most southern European populations of the nominal subspecies; spots of white hairs of disc of T6 reduced to two well-separated spots (Fig. 35 View Figures 32–39 ), a condition otherwise not frequently observed in M. leachella . Terga 2-6 laterally with numerous erect dark hairs; such dark hairs are present in the UK, in Central Europe and on Sardinia and Corsica, but not elsewhere (e.g., in Greece, Turkey), where dark hairs are restricted to T5-6. Vertex and scutum covered with black hairs intermixed with light hairs. Vertex punctation particularly coarse and sparse (Fig. 42 View Figures 40–45 ), similar to or even coarser than in the UK (Fig. 40 View Figures 40–45 ) or central European populations, but unlike in southern Europe, where the vertex punctation is comparatively small and dense (cf. Figs 41 View Figures 40–45 , 43 View Figures 40–45 ). Punctation on disc of T4 comparatively dense (Fig. 38 View Figures 32–39 ), on average denser than in other populations (Fig. 37 View Figures 32–39 ), except in M. leachella densipunctata ssp. nov. from Cyprus (Fig. 39 View Figures 32–39 ). There is however considerable variation in this character in M. leachella sensu lato and the condition observed in Crete is within the observed range of variation in the species. Megachile leachella cretica ssp. nov. shows a combination of characters present in southern European (in particular the snow white vestiture) and central or northern European populations (dark hairs laterally on the terga, coarse punctation on the vertex).
Male: nearly identical to the nominal subspecies (Fig. 46 View Figures 46–56 ); the front tarsal segments 2-4 are more consistently orange, approaching the condition observed in M. leachella densipunctata ssp. nov. (cf. Fig. 52 View Figures 46–56 ) (usually at least partly dark brown in other populations of M. leachella ; Figs 48 View Figures 46–56 , 49 View Figures 46–56 , 51 View Figures 46–56 ); the preapical process of the gonostylus (Fig. 56 View Figures 46–56 ) appears to be slightly shorter on average than in the nominal subspecies (Fig. 54 View Figures 46–56 ), but only few males were available for study.
Etymology.
The subspecies epithet refers to the geographic distribution of this taxon, which is probably restricted to the Island of Crete.
