List of Hemiptera-Heteroptera of Las Vegas Hot Springs, New Mexico, collected by Messrs. E. A. Schwarz and Herbert S. Barber

A New Crophius Stål (Hemiptera: Heteroptera: Oxycarenidae) from Mexico and Arizona, USA and Designation of a Lectotype for Oxycarenus scabrosus (Uhler)

“…However, Barber (1938) failed to publish the lectotype designation in his revision of the genus. Based on Uhler's (1904) apparent error in reporting the collection dates and the apparent loss of the specimen collected on 12 August 1901, we believe Barber was correct in recognizing the specimen collected on 2 August 1901 as a lectotype. We hereby designate the 2 August specimen, a female, as the lectotype for Oxycarenus scabrosus Uhler, 1904 (USNMENT01844300 barcode label, here added).…”

“…Based on Uhler's (1904) apparent error in reporting the collection dates and the apparent loss of the specimen collected on 12 August 1901, we believe Barber was correct in recognizing the specimen collected on 2 August 1901 as a lectotype. We hereby designate the 2 August specimen, a female, as the lectotype for Oxycarenus scabrosus Uhler, 1904 (USNMENT01844300 barcode label, here added). The second specimen, also a female, collected on 8 August, is here considered a paralectotype.…”

“…The unique hemelytral cross veins in Mayana are unique in the family and, thus, along with the more pubescent body, appear to justify maintaining it as a separate genus. Uhler (1904) described Oxycarenus scabrosus based on three specimens he reported were collected on 12 August 1901 at Las Vegas Hot Springs, New Mexico by E. A. Schwarz and H. S. Barber. Examination of two of the three specimens in the USNM collection indicate that Uhler appears to have mistakenly stated all three specimens were collected on 12 August.…”

“…Subsequent researchers (Van Duzee 1910, Barber 1938) largely adopted Stål's generic limits, although Van Duzee (1910) indicated the labium of Crophius scabrosus (Uhler) reaches the middle of the metasternum and Henry et al (2015) noted that the fore femur sometimes has a tiny second spine. Uhler (1904) described C. scabrosus (as Oxycarenus scabrosus) based on three specimens collected in 1901 from Las Vegas Hot Springs, New Mexico. Uhler's brief narrative described the labium reaching behind the middle coxae.…”

Phylogenetic relationships and revised classification of the true bug infraorder Dipsocoromorpha (Insecta: Hemiptera: Heteroptera)

“…Although not difficult to collect using passive trapping techniques, litter bugs are small (0.5–3 mm), mostly restricted to undersampled wet tropical and subtropical environments around the world, and therefore few specialists have focused on the group, resulting in few curated specimens in natural history collections. The taxonomic history of Dipsocoromorpha started in the late 19th Century (Sahlberg, 1875; Reuter, 1894; Uhler, 1904), then collectively referred to as Cryptostemmatidae. Monographs of the New World fauna (McAtee and Malloch, 1925) and of Schizopteridae with emphasis on Trinidad (Emsley, 1969) remained for a long time the two taxonomically most comprehensive treatments.…”
