HOLOTYPE

Flat form morphology, separated from A1335. All Laubierus alvini voucher material from AD4502 was cited as A1335 in Aguado & Rouse, 2011, with ethanol material pooled as A1500; for simplicity, cite as A1335 going forward. Total 10 individuals collected from AD4502: 2 split formalin/ethanol (S2 mussel 8), 2 whole in glute (mussel 9), 1 split osmium/ethanol (spec 1 from mussel 6), 1 split glute/ethanol (spec 2 from mussel 6), 1 split form/eth (spec 1 from mussel 4), 1 split glute/eth (spec 2 from mussel 4), 1 osmium (spec 3 from mussel 4), 1 whole ethanol (unspecified mussel). Originally catalogued as: A1335 (formalin, 2 anteriors total: 1 anterior from mussel 4, 1 narrow morph anterior from mussel 8), A2282 (formalin: 1 flat morph anterior from mussel 8, previously part of A1335), A1500 (ethanol, 6 posteriors total: 2 from mussel 8, 2 from mussel 6, 2 from mussel 4; field book also notes 1 whole in ethanol from unspecified mussel), A1501 (glute: 2 whole from mussel 9, 1 anterior from mussel 6, 1 anterior from mussel 4), A1502 (osmium: 1 whole from mussel 4, 1 anterior from mussel 6). Photos: 7350-7359 whole ethanol individual, unspecified mussel; 7360-7374 in situ; 7413-7414 S2 mussel 8; 7416-7419 mussel 9; 7420-7424 mussel 6; 7433-7437 mussel 4.
