Leiparthrum mandibulare

Thomas Vernon Wollaston published this drawing in his book ‘Insecta Maderensia’ in 1854. In the book he thanks Westwood for providing the illustrations, ‘Particularly, however, would I draw attention to the valuable help which I have received from J. O. Westwood, Esq., whose pencil has been so elaborately employed in the figures which I am thus enabled to attach, and by whom many of the minutest of the dissections were accomplished, — with a degree of delicacy, moreover, to which I did not myself at the commencement of this Work (though I have since succeeded in anatomizing the larger portion of them, likewise) lay claim.’

223. Leiparthrum mandibulare, Woll. (Tab. V. fig. 9.). Wollaston wrote the following about this species:

‘There are few insects which have given me more trouble in the determination of them than the present one ; for, unfortunately, the unique example which I possess (extracted from out of a cobweb, in a dead state, beneath the bark of a Spanish chestnut-tree at Santa Anna) is too much mutilated to afford a full view of all its parts.’
