Sorex ibarrai Matson and McCarthy 2005
No full textSorex ibarrai Matson and McCarthy, 2005 Ibarra’s Shrew Sorex veraepacis ibarrai Matson And McCarthy, 2005: 68. Type locality: “ Guatemala, Departamento de El Progreso, Municipio San Augustín Acasaguastlan [sic], Reserva de Biosfera Sierra de las Minas, Cerro Pinalón, Camino de las Torres, 2700 m; 15 ° 4'54" N, 89 ° 55'59" W. Holotype. Adult, female, skin, skull, and partial postcranial skeleton; CMNH No. 113283, collected 3 May 1998 by John O. Matson and field party (original number JOM 6823, M685), the animal was lactating. Distribution. Known from mountains south and southeast of Cobán, in Alta Verapaz, Baja Verapaz, and El Progreso, Guatemala. Diagnosis. Sorex ibarrai is a member of the Sorex veraepacis species group. It is the largest member of this species group (Table 1 and Figure 5) and one of the largest New World Sorex. U3 is usually <U4, but in some individuals U3 Ĺ U4. Pelage color of the adult female holotype was reported as Clove Brown above, scarcely paler below, by Matson and McCarthy (2005). Upon reassessment, we now regard the color as being Chaetura Black. Specimens of S. ibarrai from the Sierra de las Minas are the darkest of the S. veraepacis species group. Some specimens have white tipped guard hairs on the dorsum. The tail is slightly bicolor. Specimens from other populations (Biotopo Quetzal, Chelemhá, Finca Chinaux, and El Limo) are essentially of the same coloration. Sorex ibarrai averages larger in all body and skull measurements than any Sorex southeast of the Isthmus of Tehuantepec (Table 1 and Figure 5), except for length of unicuspid toothrow, which less than in S. chiapensis, S. veraepacis, and the new Sierra Madre species. Description. Sorex ibarrai differs from S. veraepacis by averaging larger in most measurements; it has a shorter mandible relative to skull length; and, its braincase is less inflated. Compared to S. chiapensis and the undescribed species from the Sierra Madre, it is absolutely larger in all measurements. It is the darkest of the S. veraepacis species group. Ecology. Found in cloud forests of the mountains south and southeast of Cobán, in Alta Verapaz, Baja Verapaz, and El Progreso, Guatemala (Matson & McCarthy 2005; Woodman 2011b; Matson et al. 2014). Dominant cloud forest trees that make up the habitat include Persea sessilis, Persea verticulata, Quercus sapoteifolia, tree ferns (Cyathea sp.), Podocarpus oleifolius, and various other conifers (Matson & McCarthy 2005; Woodman et al. 2012). Known altitudinal range is 1475 m to 2800 m. Woodman et al. (2012) summarized data on reproduction in S. ibarrai. Essentially, most reproduction (pregnant or lactating individuals) occurs in the wet season (April through July), with limited reproduction in the drier months. This same pattern has been found in many cloud forest small mammals (Rickart 1977; Vásquez et al. 2000; Matson et al. 2012). Small mammal associates include Cryptotis goodwini, Habromys lophurus, Handleyomys rhabdops, Heteromys desmarestianus, Marmosa mexicana, Microtus guatemalensis, Nyctomys sumichrasti, Peromyscus grandis, P. oaxacensis, Reithrodontomys microdon, R. sumichrasti, R. tenuirostris, and Microtus guatemalensis (Matson & McCarthy 2005; Matson et al. 2014).

The Dos Tanques, Dos Fuentes Locality: A Report
No full textThe Dos Tanques, Dos Fuentes locality is a low lying area of Cedar Mesa in the southern part of the Bears Ears NM, in SE Utah. This report is on the archaeology of that area and in particular the results of fieldwork carried out in 1991. “The Cedar Mesa Project” (CMP) was an archaeological project initiated in 1971 (Lipe and Matson 1971, Matson 1991:73- 101), directed by William Lipe and me and funded by the National Science Foundation in 1972 (Lipe and Matson 1972) and 1974 (Lipe and Matson 1974). We ran large field projects in 1972 through late 1975 (Matson and Lipe 1975, 1978, Matson, Lipe and Haase, 1988, 1990). A closely related contract project was directed by Lipe in 1976 (Lipe, Matson and Powers (1977). This project provided the impetus for a variety of other archaeological researches in later years, continuing into the 2020s. The Dos Tanques, Dos Fuentes (DTDF or Dos Tanques) investigation consisted of fieldwork in 1991 and a short visit in 1992 all funded by a grant to Matson and Dohm in 1991 by the Canadian Social Sciences and Humanities Research Council (SSHRC) (Matson and Dohm 1990, Matson and Dohm 1994)
Achagua velata Matson 2023, n. sp.
No full text<i>Achagua velata</i> Matson, n. sp. <p>(Figs. 4, 8, 11, 12)</p> <p>LSID: 0E4A82F4-6BDF-43BE-86F8-572966809E46</p> <p> <b>Diagnosis.</b> The following diagnosis is based on information from a single individual of <i>A. velata</i>, and caution should be exercised when interpreting it. As of now, <i>Achagua velata</i> is currently the only member of the genus known to inhabit the Guianan moist forests of northeastern South America. This species bears a conspicuous antemedial black spot along the forewing inner margin and a weakly gray, discal, reniform spot that are absent in both <i>A. magna</i> and <i>A. obsoleta</i>. The terminal band on both wings is thicker and more complete than in other congeners. The male genitalia of <i>A. velata</i> lack a spatulate dorsal process of the uncus, a postmedial digitate protuberance on the costa, and cornuti on the vesica, all of which are found in <i>A. magna</i> and <i>A. obsoleta</i>. While male <i>A. velata</i> shares many genitalic similarities with <i>A. cooperae</i>, the dorsal process of the uncus appears knob-like in <i>A. cooperae</i> (Fig. 7a), whereas in <i>A. velata</i> (Fig. 8a), it is more uniform in shape. <i>Achagua velata</i> and <i>A. cooperae</i> may also be separated by their COI barcode (see Molecular characterization).</p> <p> <b>Description. MALE.</b> Forewing length, 17 mm (n = 1).</p> <p> <b>Head.</b> Antenna mostly bipectinate, but with gradually diminishing rami that are absent in distal third of antenna; scales above white and light gray, rami dark gray to black. Vertex white; frons mostly light gray. Labial palpus short, decumbent, 1.5x diameter of eye, light gray and white. Chaetosemata in transverse row.</p> <p> <b>Thorax.</b> Patagium, tegula, and mesothorax admixture of gray and white scales. Legs mostly white and mottled with gray; epiphysis well-developed; hind tibia with hair pencil (not easily visualized in holotype); tibial spur formula 0–2–4.</p> <p> <b>Forewing.</b> Pearly-white; widely scattered with inconspicuous light gray scales. Basal and costal areas lightly maculated with gray to brown scales. Subtle, light gray, transverse antemedial line, and weakly gray, discal, reniform spot. Inner margin with antemedial black spot. Terminal area broadly maculated with brown scales. Underside patterned as in upperside, but darkened areas more diffuse and given more toward black.</p> <p> <b>Hindwing.</b> Pearly-white except for complete, broadly dark brown outer margin. Underside patterned as in upperside.</p> <p> <b>Abdomen.</b> Admixture of gray and white. Third sternite of male abdomen with comb of setae.</p> <p> <b>Genitalia</b> (Fig. 8). Uncus abruptly widened at base; dorsal and ventral processes thumb-like. Base of gnathos subquadrangular, with upcurved, heavily sclerotized, pointed apical projection; projection lightly papillated. Valve elongate and large with heavily sclerotized costa; apex strongly falcate. Anellar processes large and triangulate, directed inward, and with apical recurved hooks.

Stamnodes disrupta Matson 2023, sp. nov.
No full text<i>Stamnodes disrupta</i> sp. nov. <p>urn:lsid:zoobank.org:act: 4F9AC763-7709-4260-877B-63C784314A85</p> <p>Figs 14, 49, 67, 80, 94–95</p> Diagnosis <p> <i>Stamnodes disrupta</i> sp. nov. may be confused with <i>S. fervefactaria</i>, <i>S. fergusoni</i>, <i>S. mariachi</i> sp. nov. and <i>S. erupta</i> sp. nov. The bright, white reticulate pattern of the underside of the hindwing and apex of the forewing stand in contrast to the more off-white to cream colour of the same areas in <i>S. fervefactaria</i>. Additionally, the lead grey patches on the hindwing underside are finely bounded by a thin dark grey edge in <i>S. fervefactaria</i> and <i>S. fergusoni</i> that is mostly absent in <i>S. disrupta</i>. <i>Stamnodes disrupta</i> is known from the northern Sierra Madre Occidental in the states of Sonora and Chihuahua, while visually similar sister species <i>S. erupta</i> is known from the vicinity of Mexico City. While the hindwing underside of <i>S. disrupta</i> bears a white, transverse medial band that gradually curves toward the tornus (see left arrow, Fig. 14b), the same band in <i>S. erupta</i> is straighter as it angles toward the tornus (see left arrow, Fig. 16b). The angle of this band affects the shape of the large lead-coloured patch near the tornus; in <i>S. disrupta</i>, this patch is more subovate, while in <i>S. erupta</i>, it is more triangulate. The basal inner margin of <i>S. disrupta</i> also appears to have more white scales along the inner edge of the large grey basal patch of the same area in <i>S. mariachi</i> and <i>S. erupta</i> (see right arrows, Figs 14b, 15b, 16b). <i>Stamnodes disrupta</i> may also be separated from <i>S. mariachi</i> by the presence of a checkered forewing fringe and oblique white patch in apical area of forewing underside.</p> <p> Male genitalia readily separate <i>S. disrupta</i> sp. nov. (Fig. 49) from <i>S. fergusoni</i> (Matson & Wagner 2020: fig. 7). <i>Stamnodes fergusoni</i> has a juxta that bears posterolateral conical processes and its vesica has a large echinate patch of cornuti; these characters are absent in <i>S. disrupta</i>. However, the male genitalia of <i>S. disrupta</i>, <i>S. fervefactaria</i>, <i>S. mariachi</i> sp. nov., and <i>S</i>. <i>erupta</i> sp. nov. are exceedingly similar with only subtle differences. While the uncus of <i>S</i>. <i>disrupta</i> (Fig. 49a) and <i>S. fervefactaria</i> is broadly swollen medially, that of <i>S. mariachi</i> (Fig. 50a) and <i>S. erupta</i> (Fig. 51a) tapers only slightly along its length and lacks an apparent medial swelling. The shield-like juxta of <i>S. disrupta</i> is larger, and more pronounced on its distal surface than in <i>S. mariachi</i>.</p> Etymology <p> The species name <i>disrupta</i> is derived from the Latin word ‘ <i>disrumpere</i> ’, meaning ‘to shatter’ or ‘to break apart’. It alludes to the broken, white, hindwing underside pattern of this moth. The phonetic similarity with visually similar <i>S. erupta</i> sp. nov. is intentional to reinforce the close relationship between these two species.</p> Material examined <p> <b>Holotype</b></p> <p>MEXICO • ♂; Chihuahua, 3 mi.

Achagua cooperae Matson 2023, n. sp.
No full text<i>Achagua cooperae</i> Matson, n. sp. <p>(Figs. 3, 7, 10–12)</p> <p>LSID: 2053905A-C10D-464D-A68F-694BF3E7E038</p> <p> <b>Diagnosis.</b> <i>Achagua cooperae</i> is currently the only member of the genus known from Central America. This species bears a conspicuous antemedial black spot along the forewing inner margin and a weakly gray, discal, reniform spot that are absent in both <i>A. magna</i> and <i>A. obsoleta.</i> The male genitalia of <i>A. cooperae</i> lack a spatulate dorsal process of the uncus, a postmedial digitate protuberance on the costa, and cornuti on the vesica, all of which are found in <i>A. magna</i> and <i>A. obsoleta</i>.</p> <p> <i>Achagua cooperae</i> is thought to be closely related to <i>A. velata</i>. One noticeable distinction is the thickness of the black terminal band on the hindwing, which tends to be thinner in <i>A. cooperae</i> compared to <i>A. velata</i>. While male <i>A. cooperae</i> share many genitalic similarities with <i>A. velata</i>, the dorsal process of the uncus appears to be knob-like in <i>A. cooperae</i>, whereas in <i>A. velata</i>, it is more uniform in shape (Figs. 7a, 8a). <i>Achagua cooperae</i> and <i>A. velata</i> may also be separated by their COI barcode (see Molecular characterization).</p> <p> <b>Description. MALE.</b> Forewing length, 17–18 mm (n = 8).</p> <p> <b>Head.</b> Antenna mostly bipectinate, but with gradually diminishing rami that are absent in distal third of antenna; scales above white and light gray, rami dark gray to black. Vertex white; frons mostly light gray. Labial palpus short, decumbent, 1.5x diameter of eye, light gray and white. Chaetosemata in transverse row; cephalic collar mostly white with few black scales.</p> <p> <b>Thorax.</b> Patagium, tegula, and mesothorax admixture of gray and white scales. Legs mostly white and mottled with gray; epiphysis well-developed; hind tibia with large hair pencil; tibial spur formula 0–2–4.</p> <p> <b>Forewing.</b> Pearly-white; widely scattered with inconspicuous light gray scales. Basal and costal areas lightly maculated with gray to brown scales. Subtle, light gray, transverse antemedial line, and weakly gray, discal, reniform spot. Inner margin with antemedial black spot. Terminal area broadly maculated with brown scales and bearing undulating, subterminal pale stripe within. Underside patterned as in upperside but darkened areas more diffuse.</p> <p> <b>Hindwing.</b> Pearly-white except for blackened terminal area. Underside patterned as in upperside but darkened area more diffuse.</p> <p> <b>Abdomen.</b> Admixture of gray and white. Third sternite of male abdomen with comb of setae.</p> <p> <b>Genitalia</b> (Fig. 7). Uncus abruptly widened at base; dorsal process larger, gradually enlarging to pronounced swelling at distal third and with knob-like apex; ventral process large and thumb-like. Base of gnathos subquadrangular with upcurved, heavily sclerotized, and pointed apical projection; projection lightly papillated. Valve elongate, quadrate, and large with heavily sclerotized costa; apex strongly falcate. Anellar processes large and triangular, directed inward, and with apical recurved hooks. Juxta with medial, elongate cylindrical process with acuminate apex. Vesica with small medial sclerotized fold; cornuti absent.</p> <p> <b>FEMALE.</b> Forewing length, 19 mm (n = 2). Outwardly undifferentiated from male.</p> <p> <b>Genitalia</b> (Fig. 10). Papillae anales rounded; posterior apophysis 2.5x longer than anterior apophysis. Lamella antevaginalis cordiform; ostium opening into short, lightly sclerotized ductus bursae. Corpus bursae posteriorly narrow, opening into ovoid anterior portion. Signum large and invaginated, appearing somewhat cone-like; surface lightly denticulate.</p> Type Material.

Notably, two individuals were collected from the Sierra de los Tuxtlas, a remote volcanic range situated along the southeastern coast of the Veracruz Gulf in Mexico. These are tentatively regarded as conspecific (see Remarks).</p> <p> <b>Biology.</b> The life history of <i>A. cooperae</i> remains unknown. Adult are known to fly from February through April.</p> <p> <b>Etymology.</b> <i>Achagua cooperae</i>, is named in honor of Loretta Faye Cooper, former Senior Development Officer, and Deputy Director for Advancement at the Smithsonian’s National Museum of Natural History. Loretta’s dedication to museum research is unparalleled, and her tireless efforts to raise awareness and secure funding for the conservation and study of the natural world make her a true champion for both people and the environment. Loretta’s support for the Area de Conservación Guanacaste is particularly noteworthy and greatly appreciated.</p> <p> <b>Molecular characterization.</b> <i>Achagua cooperae</i> is represented in BOLD by the BIN: BOLD:AAM6724 (n = 5). The pairwise distance to the nearest neighbor, <i>Achagua velata</i> (n = 1, French Guiana), is about 3.8%.</p> <p> <b>Remarks.</b> I tentatively regard two individuals from the Sierra de los Tuxtlas of Veracruz, Mexico, as <i>A. cooperae</i>. However, I have opted not to include these individuals in the type series. While the genitalia of both sexes in this Mexican population are consistent with those in Costa Rica, the Sierra de los Tuxtlas is a region characterized by biological endemism (Sánchez-González <i>et al</i>. 2008), and further, this population is disjunct from the remaining known distribution of <i>A. cooperae</i>.</p> <p>The male phallus depicted in Figure 7b may give the impression of a spinate cornutus. However, this is an artifact of the preparation and the structure in question is rather a sclerotized fold.</p>Published as part of <i>Matson, Tanner A., 2023, The known species of the genus Achagua Rindge, 1983, with the description of three new species from the Neotropics (Geometridae: Ennominae), pp. 565-576 in Zootaxa 5352 (4)</i> on pages 571-573, DOI: 10.11646/zootaxa.5352.4.7, <a href="http://zenodo.org/record/8426638">http://zenodo.org/record/8426638</a>
A Conversation with Bill Lipe (interview format)
No full textOn April 7, 2006, at Washington State University, Tim Kohler and R. G. Matson interviewed Bill Lipe about the book Tracking Ancient Footsteps: William D. Lipe's Contributions to Southwestern Prehistory and Public Archaeology. A few days before the interview, they gave Lipe a list of a half-dozen possible topics. About 90 minutes of open-ended conversation then began, later transcribed by Diane Curewitz. What follows is a lightly edited version of that conversation, with inserts noted by square brackets.Lipe, William D. (with Timothy Kohler and R.G. Matson). 2006.
