Three New Species Of South American Checkered Beetles (Coleoptera: Cleridae: Clerinae), Weston Opitz

Insecta Mundi

Three new species of Enoclerus Gahan (Coleoptera: Cleridae) are described and illustrated. They are: Enoclerus minas Opitz from Colombia and Brazil, E. salta Opitz from Argentina, and E. thomasi Opitz from Bolivia.

Corporaal (1950: 14) lists 185 species of Enoclerus Gahan (Coleoptera: Cleridae: Clerinae). I know of over 60 undescribed species. It is a daunting task to organize such a high number of species into some sort of taxonomic revision, which cannot be provided at this time. However, some of these new species can be described that will be added to a larger work at a later date. Such descriptive …

Aphelocerus Thomasi, A New Species Of Checkered Beetle (Coleoptera: Cleridae: Clerinae) From Mexico, Jacques Rifkind

Insecta Mundi

Aphelocerus thomasi Rifkind, new species (Coleoptera: Cleridae: Clerinae), is described from the state of San Luis Potosí, Mexico. This beetle is named for the late Michael C. Thomas, in recognition of his lifetime of contributions to the study of Coleoptera.

Recent nomenclatural and descriptive work by Leavengood (2014), Leavengood and Garner (2014), Barr (2018) and Leavengood and Rifkind (2020) have made changes to the approximately 120 described species of New World Hydnocerini (i.e., Phyllobaenus Dejean, Isohydnocera Chapin and Wolcottia Chapin). Over 100 of these species comprise the genus Phyllobaenus. Mexico and Central America are home to about half …

A New Species Of Euxestoxenus Arrow (Coleoptera: Euxestidae) From Thailand, Adam Ślipiński

Insecta Mundi

A new species of Euxestoxenus Arrow (Coleoptera: Euxestidae), E. thomasi Ślipiński, is described from northern Thailand. The species differs from all Oriental and most of African species of Euxestoxenus by a 10-segmented antenna and glabrous, polished dorsum.

Euxestidae is a small and poorly known family of Coccinelloidea that currently includes 11 genera and about 70 species distributed mostly in the Old-World tropics and subtropics but extending into temperate areas of North America and Australia (Ślipiński 1990). The biology of the Euxestidae is mostly unknown but it appears that all species are fungivores, commonly found in rotten wood, forest litter, in …

A New Species Of Ataenius Harold (Coleoptera: Scarabaeidae: Aphodiinae) From The Southeastern United States, With A Lectotype Designation, Kyle E. Schnepp, Krystal L. Ashman

Insecta Mundi

A new species of Ataenius Harold, Ataenius thomasi Schnepp and Ashman (Coleoptera: Scara­baeidae: Aphodiinae), from Florida, Georgia, and Mississippi, U.S.A. is described. The lectotype for Ataenius brevis Fall is designated.

In the United States and Canada the genus Ataenius Harold (Coleoptera: Scarabaeidae: Aphodiinae) contains 46 species (Stebnicka 2007; Smith 2009). The most recent faunal review of this genus in these countries was completed by Cartwright (1974).

Validation Of Chrysina Valentini Zubov And Ivshin, 2019 (Coleoptera: Scarabaeidae: Rutelinae) By Morphometric And Cuticular Reflectance Analyses, David C. Robacker, Karen M. Robacker, William C. Warfield

Insecta Mundi

Micromorphometric analyses of genital capsules and comparison of adult cuticular reflectance of two species of Chrysina Kirby (Coleoptera: Scarabaeidae: Rutelinae) support the status of C. valentini Zubov and Ivshin, 2019 as a valid species. Compared with its closest relative C. optima (Bates, 1888), capsules of C. valentini are proportionately wider at the base of the parameres than those of C. optima, and taper toward the apex more abruptly. Reflectance of C. valentini under natural light appears slightly greenish while C. optima is uniformly reddish. The number of teeth on the protibia and the shape of the mesosternal process, characters …

Checklist Of The Caddisfly Family Rhyacophilidae (Insecta: Trichoptera) In India, Tabaraq Ali, Sajad H. Parey, Manpreet S. Pandher, Malkiat S. Saini

Insecta Mundi

The present checklist covers the fauna of the Trichopteran family Rhyacophilidae Stephens, 1836. Based on extensive surveys done during 2003–2019 and previous species records, we find that the family Rhyacophilidae is represented by two genera and 184 species in India. The genus Rhyacophila Pictet contains 165 species in India while the genus Himalopsyche Banks contains 19 described species. The Indian Himalayan region is inhabited by more species than the rest of India.

First Record For Cypherotylus Dromedarius (Lacordaire) (Coleoptera: Erotylidae) From Panama, Brian J. Armitage, Alonso Santos Murgas

Insecta Mundi

Cypherotylus dromedarius (Lacordaire, 1842) (Coleoptera: Erotylidae) was described from French Guiana. Information about its current distribution is scattered throughout the literature and the internet. Specimens of this species were recently observed and photographed in the Boquete area, Chiriqui Province, Panama, and constitute a new record for the country of this species. Subsequently, we located two specimens deposited in the National Reference Collection of the G. B. Fairchild Museum of Invertebrates, University of Panama, from the same locality in Chiriqui Province. We summarize the distribution of this species from scattered sources and provide five new records.
