A new tribe is established in the Limnichidae, Limnichinae, for a new genus and species, Wooldridge us perforatus, from Sabah, Malaysia. Two autapomorphic characters distinguish Wooldridgeini from the two other tribes ofthe subfamily Limnichinae; 1) the mesotarsus and metatarsus join their respective tibia ventrally (medially) and preapically instead of the usual apical only connection and 2) a large pore, presumed to be an opening of a prothoracic gland, is present on each hypomeron. Distinguishing characters are illustrated by scanning electron micrographs and line drawings. A key to the three tribes included in the Limnichinae is provided.
New Cantharidae (Coleoptera) from the Dominican Republic and Haiti. - The material dealt with in this paper was sent for identification by Dr. M.C. Thomas from the Florida State Collection of Arthropods (FSCA). The following species new to science are described: Tylocerus basitestaceus; Silisdiscodon thomasi, S. lavegaensis; Silis superba; Tytthonyx s.str. coriaceipennis, T. s.str. barahonaensis, T. s.str. larimarensis. All holotypes and some paratypes are deposited in the above mentioned collection.
Review of the family Bochicidae : with new species and records (Arachnida: Pseudoscorpionida)
(1998)
A history of the family is presented. All of the genera and species previously assigned to the family are reviewed, and 4 new species are described: Leucohya par va from Venezuela and Guyana, Mexobisium venii from Belize and Guatemala, M. dominicanum from the Dominican Republic, and Paravachonium sprousei from Mexico. Two subfamilies are established: Bochicinae (including the genera Antillobisium, Bochica, Troglobochica, Troglohya, and Vachonium) and Leucohyinae (including Apohya, Leucohya, Mexobisium, and Paravachonium).
The family Epipsocidae is defined, with the addition of one character not previously used. The genus Dimidistriata Li and Mockford is removed from Epipsocidae and tentatively placed in the family Dolabellopsocidae. The genus Parepipsocus Badonnel remains unplaceable to family. Eleven genera are recognized within Epipsocidae. Bertkauia Kolbe, which had been synonymized with Epipsocus, is recognized as a valid genus. Definitions of genera based on the type species and seemingly close relatives result in 38 new combinations. Epipsocus Hagen, which previously held most of the species, now serves a dual function, with 15 species in the strict sense and 15 species 'incertae sedis' retained in it, pending further investigation. Goja Navas, previously with 2 species, now contains 10, with 8 transferred from Epipsoc us. Mesepipsocus Badonnel, previously with 5 species, receives 24 more from Epipsocus and 1 from Dicropsocus. Eight species are transferred from Epipsocus to Epipsocopsis Badonnel. Notable consistency in geographic distributions of genera results from these transfers. Some evolutionary trends within the family are discussed. Epipsocus delicatus (Hagen) and E. completus Banks, which had been assigned by recent authors to the genus Pseudocaecilius Enderlein (Family Pseudocaeciliidae), are returned to the Epipsocidae and assigned to Epipsocopsis. A lectotype is designated for E. delicatus.
Apionion (type species Apion crassum Fall) is described for 14 species formerly assigned to the Apion annulatum species group of Coelocephalapion Wagner, namely, championi Sharp, crassum Fall, derasum Sharp, dilatatum Smith, fenyesi Kissinger, howdeni Kissinger, inflatipenne Sharp, latipenne Sharp, latipes Sharp, len tum Sharp, neolentum Kissinger, samson Sharp, and subauratum Sharp from North and Central America, and annulatum Gerstaecker from South America, all originally included in Apion Herbst. Four new species are described: delion (panama), eranion (Costa Rica, Panama), humongum (Mexico, El Salvador, Honduras), and sapphirum (Mexico, Costa Rica). New records and/or supplemental descriptions are given for championi, derasum, dilatatum, fenyesi, howdeni, inflatipenne, latipenne, latipes, and neolentum.
In our checklist of the Alticinae of Central America and Mexico (Furth and Savini, 1996), there were some species whose status or generic combination needs clarification. In preparing the
1996 checklist the authors referred to some unpublished notes of Jan Bechyne in order to understand his system of alticine names and to clarify to which genera he considered various species to belong.
Larvae of the three common North American species of Phylocentropus (Trichoptera: Dipseudopsidae)
(1998)
The caddisfly genus Phylocentropus includes 7 extant species globally, of which 5 occur in eastern North America and 2 in eastern Asia. Larvae of the 3 most common North American species [Phylocentropus carolinus Carpenter, P. lucidus (Hagen), and P. placidus (Banks)] were associated with identifiable adults and diagnostic characters are described. Larvae ofthese 3 species may be distinguished by overall length of mature larvae, head color pattern, and number of spines on the hind tibiae. Larvae of other species of this genus are unknown.
Two new species of Chariergus White are described from Brazil: Chariergus caeruleus, from Bahia, Minas Gerais and Espirito Santo and C. paranaensis., from Parana, Santa Catarina and Rio Grande do SuI. Ethemon brevicorne, sp. n. is described from Argentina (Cordoba). A key to species of Chariergus is added.
