The MHNG collection contains two microscope slide preparations: 1) a slide (MHNG-ARTO-18463) with gonopods with labels with “ Trachyiulus humberti Carl ssp. willeyi Carl ” and “Gonop. I et II ” handwritten on them respectively; 2) a slide (MHNG-ARTO-18464) with legs with labels with “ Trachyiulus humberti Carl ssp. willeyi Carl ” and “ ♂ type Bp. 1 et 2” handwritten on them respectively. Both belong to the holotype . The rest of the holotype is in the BMNH . The MHNG alcohol collection contains some specimens collected after the date of the publication of the original description and these are therefore not part of the type series.
