Stenopelmatopterus junior synonym of Stenopelmatus.

On the basis of our expanded DNA information ( Fig. 10 ), we declare Stenopelmatopterus Gorochov a junior synonym of Stenopelmatus . Gorochov (1988) erected his new genus to include 3 previously described species of Stenopelmatus : S. sartorianus (type species of genus), S. sallei , and S. sumichrasti . Later in this paper, we make the following changes: (1) Both S. sallei (type a female nymph from “ Mexico ”) and S. sumichrasti (type a male nymph from “ Mexico ”) are declared nomen dubium. (2) Stenopelmatopterus sartorianus (type an adult female from the Mexican state of Chiapas) is moved back into Stenopelmatus because it is recovered in Clade 2, along with other species of Stenopelmatus from Mexico, Honduras, and Costa Rica. Plus, none of the supposedly distinguishing characteristics of Stenopelmatopterus are unique and diagnostic of that genus: (1) While no other species has fully formed wings, three species ( S. piceiventris , S. chiapas , and S. sanfelipe ) are micropterous (using terminology of Slater 1975). (2) Slender legs are also seen in S. cusuco , S. ater , and S. piceiventris , among others ( Table 1 ). (3) Reversed V-shaped furrows are common among other wingless species of Stenopelmatus (see photos later in this text), and are even present in some taxa of Ammopelmatus . Additionally, in our series of S. sartorianus , most individuals do not have a complete V shaped furrow – and some adult specimens barely have lateral carinae. (4) Large eyes are widespread within the subfamily, especially in Ammopelmatus . Perhaps, most importantly, S. sartorianus is recovered with, and looks and behaves like many other JCs in Clade 2. Retaining it as a monotypic genus would only serve to obscure its affinity with the other taxa to which it is most closely related to on the basis of molecular phylogenetic analyses.

FIGURE 10. Coalescent-based species tree estimation using ASTRAL. Ammopelmatus clade has been collapsed. Green circles on the nodes denote 100% bootstrap support values, and the support values below 100% are shown as numbers. In samples F2004, F2152, and F2238, the species name is preceded by a “?” mark because the identity of the individual is not certain. These three samples are discussed in the text under each presumptive species.
