Leucothoe merletta sp. nov. urn:lsid:zoobank.org:act: 6C2BCD72-777F-4825-B595-A23EBFE445C9 Figs 5, 13-14 Diagnosis Eyes round, yellowish. Mandibular palp art. 3 nearly as long as art. 2. Cx 2 smooth, in shape of a parallelogram, anterodistal corner acutely lengthened. Cx 4 also with anteridistal corner acutely lengthened, but posterior margin much shorter than anterior one. Gn 1 propodus l:w = 4, dactylus reaching nearly 1/2 of propodus length. P 5-7 basis oval, with regularly rounded hind margin, ratio l:w about 1.5; posterior margin in P 7 smooth. Ep 2 distoposterior corner slightly upturned, Ep 3 posterodistally with rectangular corner. T l:w not known. Etymology In Italian “merletto” is the bobbin lace; as the very acutely elongated Cx 2 and Cx 4 can remind on lacecollars, this epitheton (Latinized flexible adjective) was coined.
