Ammopelmatus irregularis (Brunner von Wattenwyl)Figs 1410–14141888. Stenopelmatus irregularis. Verhandlungen der Kaiserlich-Koniglichen Zoologisch-Botanischen Gesellschaft in Wien 38:261. Syntype series included specimens from Arizona, Mazatlán, and California, although measurements were only given for a female 47 mm in length, with a hind femur of 16.5 mm and hind tibia of 16 mm in length. Unfortunately, we are not told which specimen these measurements are from; nor how many specimens there are in the syntype series from these localities. We now address these syntype localities in order: (1) An Arizona specimen was designated as lectotype by Karny, in 1929 (see below). (2) Harald Bruckner of NHMW Vienna has located (pers comm to DBW 10-vii-2023) 3 adult females (Fig. 1414), from Mazatlán, in Box 25. All 3 adults appear to have been collected by Steindachner, according to H. Brucker, but no more information is available. We find the following notable spination for these individuals: Female #1 has 3 fore tibia spurs and 8 middle leg calcars; Female #2 has 2 fore tibia spurs and 8 middle leg calcars, 2 spurs; and Female #3 has 3 fore tibia spurs and 8 middle calcars. All three females have 2 ventral spurs on the middle leg tibia; with the hind leg tibia having 2 outer and 5 inner spines with 2 ventral spurs. Surprisingly, these specimens from Mazatlán are the only JC records from the Mexican state of Sinaloa that we are aware of. (3) We have not found a ‘type’ labeled specimen from California, nor did Hubbell (1960) in any European Museum, although given the diversity of Ammopelmatus taxa in California, any specimen(s) in the syntype series from ‘California’ would be of little use without more precise locality information.1916. Stenopelmatus longispina. Hebard, Journal New York Entomological Society, 24, 80, as a junior synonym of S. longispina.1929. Stenopelmatus irregularis. Karny, Annals Naturhistorisches Museum Wien 43:41. Karny (1929) designated, as lectotype, the adult female from Arizona (Fig. 1410) with these labels (Fig. 1411): (1) Coll. Br. v. W. ex Mus. Godeffroy Arizona (2) 10.439 (3) red label Type (4) Coll. Nat. - Mus. Wien (5) S. irregularis. Measurements in mm: Body length 36.3, hind femur length 15.8, hind tibia length 15.6. Fore tibia with 3 ventral spurs; Middle tibia with 8 calcars, 2 ventral spurs; Hind tibia (Fig. 1412) with 2 outer and 5 inner spines but inner spines on both legs in unusual arrangement: most distal is small while 2 nd spine is larger and offset while #3 through #5 are normal in position. There are 2 ventral spurs on the rear leg. Ovipositor (Fig. 1413A), and the face is without a furrow (Fig. 1413B). Specimen in NHMW Vienna.1937. Stenopelmatus longispina. Karny, Genera Insectorum, 206, 44.2021. Ammopelmatus irregularis. Weissman et al. Zootaxa, 4917, 1–122. Moved to Ammopelmatus based on rear leg spines and geographic location.We are unsure what to do with this name because no species in the Longispinus Group, as A. irregularis was synonymized by Hebard (1916), occurs in Arizona; and the whole syntype series lacks an adult male. We thus change its status to nomen dubium given the uncertainty as to its identity and our lack of any morphologically similar Arizona specimens: In Table 25 (p. 44) we summarize the characters of the 3 taxa that we recognize in Arizona: A. grayi, A. navajo, and A. portal. None of these species has the particular rear leg inner spine #1 seen in the lectotype.Derivation of name. We wonder if “irregularis ” refers to the alignment of the rear leg tibial spines not being linear, but irregularly spaced? This condition is also seen in certain specimens of at least the following Ammopelmatus taxa: A. bigsur, A. catalinae, A. descansodunes, A. longispinoides, A. mtshasta, and A. rentzi. This rear inner leg spine arrangement is also similar to that seen in the neotype of Stenopelmatus talpa, and the probable adult female of S. talpa in Vienna (Weissman et al. 2021, p. 98).Discussion. The three adult females from Mazatlán, in the collection of NHMW Vienna, are intriguing. First off, how did these specimens get into that collection? If collected by Steindachner, were they collected during his time aboard the Hassler Expedition, which went from Boston to San Francisco between 1871 and 1872? This appears unlikely since according to James Henry Blake’s summary of the Hassler Expedition (https://viewer.lib.harvard. edu/example/manifest/?manifestId=https://iiif.lib.harvard.edu/manifests/drs:11806543&_gl=1*ez0z1w*_ga*MzQ 0NzczMDUxLjE3NDcxNTc0NDM.*_ga_3CXC97RWEK*czE3NDcxNTc0NDMkbzEkZzEkdDE3NDcxNTgxNj UkajYwJGwwJGgw), they stopped in Acapulco and Magdalena Bay, Mexico, but not in Mazatlán. And how did the specimens get to Vienna? Since most of the material from that expedition was supposedly deposited at Harvard or The Smithsonian (https://siarchives.si.edu/collections/auth_exp_fbr_eace0019)? And the three specimens are dated 1879, which might represent when they were given to Brunner von Wattenwyl. Perhaps Steindachner visited Mazatlán at another time?We also refer the reader to p. 521, where we describe A. sonoraensis, the only JC specimen known from the Sinaloa neighboring Mexican state of Sonora.
