HD/PGE typically evolves from male heterogamety (i.e., systems with X chromosomes), however why X chromosomes are important for the evolution of HD/PGE remains debated. The Haploid Viability Hypothesis argues that X chromosomes promote the evolution of male haploidy by facilitating purging recessive deleterious mutations. The Intragenomic Conflict Hypothesis instead argues that X chromosomes promote the evolution of male haploidy due to conflicts with autosomes over sex ratios and transmission. To test these hypotheses, we studied lineages that combine germline PGE with XX/X0 sex determination (gPGE+X systems). -

Abstract The new genus Borgesminthurinus gen. nov. from Bolivia shares with Sminthurinus the presence of antennal segment IV undivided, antennal segment III with one papilla; sacs of ventral tube smooth; each tenacular rami with 3 teeth and a basal appendix. They also have dens with ventral chaetotaxy reduced and lack mucronal seta; but new genus clearly differs in having thick and barbulate setae on head and body, lacking neosminthuroid setae on abdomen and the presence of seta a0 on Abd. VI acuminate. The new genus differs from Katianna which has divided antennal segment IV, vertex of head with spine-like setae and setae of the body long and smooth. Key words: Systematics, Neotropical species, La Paz, Borgesminthurinus andinus sp. nov. Introduction Bolivia is one of the countries from South American where Collembola are almost unknown. -

Among animals, insects had a staggering terrestrialization success, due to traits usually associated with post-embryonic life stages, while the egg stage has been largely overlooked in comparative studies. In many insects, after blastoderm differentiation, the extraembryonic serosal tissue wraps the embryo and synthesizes the serosal cuticle, an extracellular matrix that lies beneath the eggshell and protects the egg against water loss. -

Allacma Fusca (L.) and Allacma Gallica (Carl) in Holland (Collembola: Sminthuridae)
170 ENTOMOLOGISCHE BERICHTEN, DEEL 33, 1.IX.1973 Allacma fusca (L.) and Allacma gallica (Carl) in Holland (Collembola: Sminthuridae) by WILLEM N. ELLIS Instituut voor Taxonomische Zoölogie (Zoölogisch Museum), Amsterdam The presence of Allacma fusca (Linnaeus, 1758) in Holland was ascertained as early as 1859 by Snellen van Vollenhoven. His figure of A. fusca is far inferior to the first published drawing of this species, given by De Geer, 1743, but his description is sufficient to recognize the species. As a matter of fact, fusca is very common in our country, as a rule easily found in any stretch of deciduous woodland between about April and October. The presence of Allacma gallica (Carl, 1899) in the Netherlands was discovered only in 1969 by J. W. Bleys in the course of a study on the ecology of epigeic Collembola. He collected a fair number of specimens in the dune area near Castri- cum (territories of the “Provinciale Waterleidingduinen Noord-Holland”) with the use of a sweeping net (Bleys, in preparation). Afterwards the present author and his wife found large colonies of gallica in the deciduous woods in the old (inner) dunes at Bergen (Oude Hof), Santpoort (Duin en Kruidberg), and Vogelenzang (Amsterdamse Waterleidingduinen). It is striking that these sites are all situated within the dune region. Although we collected fusca in large numbers everywhere in the country, and specially searched for fusca and gallica on several occasions, we never found the latter species outside the dune area. It seems that outside of the Netherlands gallica is not common either. So far the species was known only from France and Switzerland. -

The University of Michigan had a few vials of specimens determined by Harlow B. Mills, and a modest num- ber was in the Robert R. Dreisbach collection at Midland, Michigan. At the beginning of my investigation very little was known about the order in Michigan, although monographs had been written on the collembolan faunae of the nearby states of Minnesota (Guthrie, 1903), Iowa (Mills, 1934) and New York (Maynard, 1951). -

A New Type of Arthropod Photoreceptor
A new type of arthropod photoreceptor Rafael Jordanaa, Enrique Baqueroa,*, Luis M. Montuengab aDepartment of Zoology and Ecology, University of Navarra, PO Box 177, 31080 Pamplona, Navarra, Spain bDepartment of Histology and Pathology, University of Navarra, PO Box 177, 31080 Pamplona, Navarra, Spain ABSTRACT A new type of photoreceptor for the phylum Arthropoda, found in the class Collembola (Arthropoda, Hexapoda) is reported. This new light-sensitive structure consists of a pair of interocular vesicles present in the genus Vesicephalus Richards, 1964 and is anatomically related to the cluster of ommatidia. The absence of a lens, the presence of a rabdome in the upper part of the vesicle and the refection and refraction of light by a hemolymph bubble with incidence to the rhabdomeric structure are the main traits of this new photoreceptor.

E-mail address: [email protected] (E. Baquero). 1. INTRODUCTION In Arthropoda, four types of photoreceptors have been classically considered: (1) the typical facetted eyes; (2) simple-lens eyes or frontal ocelli with cup-shaped retina; (3) median eyes, typical of larvae (‘nauplius’ eyes in Crustacea) which are classified as frontal eyes or frontal ocelli when they persist in adults; and (4) the frontal organs (originally paired) found in Collembola, most Crustacea and other Arthropoda. In Hexapoda, the nerve fibers arising from the latter end in special areas of the central proto-cerebrum called ocelli center (Marlier, 1941; Paulus, 1972b, 1979). Since the early days of the study of photoreceptors in the class Collembola, two types were always described.
