Leschen, Richard A. B. & Bowestead, Stanley, 2001, Synonymical Notes For Corylophidae And Cryptophagidae (Coleoptera: Cucujoidea), The Coleopterists Bulletin 55 (3), pp. 312-316 : 312-314

Corylophidae

North American Peltinodinae

Holopsis Broun, 1883: 498 . Type species: Holopsis nigellus Broun, 1883 (designated by Bowestead 1999).

Corylophodes Matthews, 1885: 160 . Type species: Corylophodes punctipennis Matthews, 1899 (designated by Paulian 1950). Synonymized by Matthews 1899: 145.

Bathona Casey, 1900: 62 . Type species: Bathona corolinae Casey, 1900 (here designated). New synonymy.

Peltinodes Paulian, 1950: 19 . Type species: Peltinodes gigas ( Abeille de Perrin, 1894) (by monotypy). Synonymized by Bowestead 1999: 23.

Notes. We examined the type specimens described by Casey (1900) that led to the generic synonymy of Bathona with Holopsis . The new combinations

are Holopsis carolinae (Casey) , H. virginica (Casey) , H. convexa (Casey) , and H. sphaericula (Casey) . Peltinodinae is a monogeneric subfamily that can be recognized by the basally open procoxal cavities (a key to the higher taxa is included in Bowestead 1999).

Material Examined ( USNM). United States: Bathona carolinae Casey ; Lectotype female (present designation) labelled ‘‘N.C. [5 North Carolina], Casey bequest 1925, Type USNM 48390, Bathona carolinae Cas. , det Holopsis carolinae (Casey) by S. Bowestead’’. Bathona virginica Casey ; labelled ‘‘Va [5 Virginia], Casey bequest 1925, virginica 3, Paratype USNM 48391, det Holopsis virginica (Casey) by S. Bowestead’’.

North American Corylophinae : Corylophini

Microstagetus parvulus Wollaston, 1861 . New Record from North America.

Notes. A dissected female confirmed that the specimens collected in Oklahoma are M. parvulus , a species introduced from the Palaearctic. Microstagetus is a genus containing two species with an Atlantic, Mediterranean, and Afrotropical distribution. Of the two described genera of Old World Corylophini , Microstagetus can be distinguished from Corylophus Stephens by having a small projecting plate on the anterior margin of the prosternum, antenna with antennomeres 4 and 6 well developed, and a vestigial spermatheca.

Material Examined (7, USNM). United States: Oklahoma, Latimer Co., VIII.1987, Karl Stephan, det Microstagetus ? by J. Pakaluk, det Microstagetus parvulus Wollaston , by S. Bowestead.

Neotropical Corylophinae : Aenigmaticini

Ectinocephalus Matthews, 1888: 105 . Type species: Ectinocephalus tropicus Matthews, 1888 (by monotypy).

Conodes Matthews, 1888: 107 . Type species: Conodes conicus Matthews, 1888 (by monotypy). New synonymy.

Notes. The synonymy of Conodes with Ectinocephalus was suggested previously by Pakaluk and Lawrence (1986) who included the genus in a paraphyletic Orthoperini . Dissections of the female type specimens confirm the generic synonymy resulting in the new combination Ectinocephalus conicus (Matthews) . Ectinocephalus can be distinguished from other members of Aenigmaticini by having the prothorax widest at the base and a 10­segmented antennal club.

Material Examined ( BMNH). Guatemala: ‘‘ Ectinocephalus tropicus Matthews ; Lectotype female (present designation), labelled ’’ Ectinocephalus tropicus Capetillo Guat. Champion [hand written by D. Sharp], figured, Capetillo Guatemala G. Champion (printed), Ectinocephalus tropicus [hand written by A. Matthews]’’; and 1 paralectotype, female, same locality; labelled ‘‘Mason number 3, Matthews number 2, Matthews coll 1904­120, Ectinocephalus tropicus [hand written by A. Matthews]’’. Conodes conicus Matthews (1888) ; Lectotype female (present designation), labelled: ‘‘ Conodes conicus Guatemala, Capetillo Guatemala G. Champion [hand written by D. Sharp], Capetillo Guatemala G. C. Champion [printed], Conodes conicus [hand written by A. Matthews], det Ectinocephalus tropicus (Matthews) by S. Bowestead’’; and 1 paralectotype, female, same locality, labelled ‘‘Mason number 4, Capetillo Guatemala G. C. Champion, Matthews coll 1904­120, Conodes conicus [hand written by A. Matthews], det Ectinocephalus tropicus (Matthews) by S. Bowestead’’.

North American Rypobiinae : Gloeosomatini

Gloeosoma Wollaston, 1854: 480 . Type species: Gloeosoma velox Wollaston, 1854 (by monotypy).

Moronillus Jacquelin du Val, 1854: 38 . Type species: Moronillus ruficollis Jacquelin du Val, 1854 (by monotypy). Synonymized by Jacquelin du Val 1859: 234.

Lewisium Matthews, 1899: 164 . Type species: Lewisium ceylonicum Matthews, 1899 (designated by Lucas 1920). Synonymized by Bowestead 1999: 129.

Gronevus Casey, 1900: 64 . Type species: Gronevus sticticus Casey, 1900 (here designated). New synonymy.

Sahlberginus Bruce, 1948: 33 . Type species: Sahlberginus inexpectatus Bruce, 1948 (by monotypy). Synonymized by Bowestead 1999: 129.

Notes. Casey (1900) described five species of Gronevus and we examined two species to confirm the synonymy above resulting in the following new combinations: Gloeosoma sticticum (Casey) , G. fuscicornis (Casey) , G. truncatum (Casey) , G. hesperum (Casey) , G. laevis (Casey) .

The tribe Gloeosomatini Bowestead contains the genera: Gloeosoma Wollaston, 1854 and Catoptyx Matthews, 1887 . Gloeosoma can be distinguished from Oriental genus Catoptyx by the procoxal cavities elongate and the presence of a prosternal process, which is effaced in Catoptyx and also has the anterior margin of the pronotum emarginate and thickened ventrally.

Material Examined ( USNM). United States: Gronevus sticticus Casey ; Lectotype (not sexed, present designation) labelled ‘‘Ia [5 Iowa], Casey bequest 1925, Type USNM 48398, sticticus, det Gloeosoma sticticum (Casey) by S. Bowestead’’. Gronevus hesperum : labelled, ‘‘Ia [5 Iowa], Casey bequest 1925, hesperus 3, Paratype USNM 48396, det Gloeosoma hesperum (Casey) by S. Bowestead’’.
