1893. Stenopelmatus lessonae . Bollettino Musei di Zoologia ed Anatomia comparata della R. Università di Torino 8(154): 3. Type series apparently included both multiple males and females, as ranges given for measurements in original publication. Lectotype male here designated ( Fig. 71 ): “ Stenopelmatus lessonae Griff. tipo Ƌ Messico.” Lectotype and allotype female (see below) both in Museo Regionale di Scienze Naturali, Torino. Measurements in mm: Body length 20.7, hind femur length 8.1, hind femur width 3.2. Lectotype adult male solid black, 5 inner and 4 outer (one spine very small) spines ( Fig. 72 ) on both rear legs. After relaxation, presence of adult hooks confirmed pressed against body. Both lateral sides of furrow visible ( Fig. 73 ) without a dorsal connection between them. New status: Nomen dubium, given the absence of a specific locality, notable physical feature, and drum, all in the presence of several small, all black JCs in Mexico .

Allotype adult female here designated with same label data as lectotype except including “..same but tipo ♀ ” Her head is reddish brown with dark brown sutures. Pronotum dark brown, legs dark reddish brown. Abdomen unstripped ( Fig. 74 ) with 5 inner and 3 outer rear leg tibial spines ( Fig. 75 ). Measurements in mm: Body length 24.1, hind femur length 8.4, hind femur width 3.3. Face ( Fig. 73 ) as in male.

Derivation of name. Michele Lessona (1823-1894) was a fellow Italian zoologist who specialized in amphibians. Apparently named in his honor by Griffini.
