Figs 73–77

Type species. Notiasemus glauerti L.E. Koch, 1985 (by original designation).

Diagnosis. Cephalic plate abuts tergite 1 across its width, without sutures ( Fig. 75 ). Forcipular tooth-plates welldeveloped but relatively small ( Fig. 76 ), much shorter than trochantero-prefemoral processes. Pleuron typical for Scolopendrini ( Figs 73, 77 ); spiracles open laterally, edges of peritrema not curved. Legs lacking tarsal spurs, with pretarsal accessory spines; tarsus 1 slightly longer than (sometimes nearly as long as) tarsus 2. Coxopleural processes conical, short and wide at base, with apical spine only ( Fig. 73 ); ultimate sternite with well-developed median longitudinal sulcus/depression. Ultimate legs of “common” shape ( Fig. 73 ), pretarsus with short accessory spines. Edgecombe & Bonato (2011: 399) also wrote: “Narrow band of uniformly long, simple bristles on each side of the labral tooth” (figs 3A, C of Edgecombe & Koch 2009).

Number of species. 1.

Sexual dimorphism. Unknown.

Remarks. Treated as a genus in Edgecombe & Bonato (2011: 399). The most recent account on Notiasemus is Vahtera et al. (2013) who based on the first molecular data for N. glauerti wrote (p. 593): “ Notiasemus is resolved within Scolopendrini and is consistently placed within Cormocephalus ” and later: “We conclude from this that the morphological evidence for a basal position of Notiasemus in Scolopendridae is probably incorrect and N. glauerti needs to be reinterpreted as a morphologically anomalous member of Cormocephalus . However, due to low nodal support within the clade, we do not yet suggest synonymy of Notiasemus with Cormocephalus ”. This point of view is also supported by the fact, that “The peristomatic structures of Notiasemus glauerti show a unique combination of characteristics of blind and ocellate scolopendromorphs” ( Edgecombe & Koch 2009: 303). Thus at the moment Notiasemus is an independent member of Scolopendrini / Scolopendrinae .
