Cryptocephalus apicalis species group is introduced and defined within the subgenus Asionus Lopatin, 1988. Cryptocephalus ergenensis Morawitz, 1863 from this group is first recorded in Eastern Kazakhstan and this form with unusual colour pattern is described herein as a new subspecies kalbensis Mikhailov, ssp. nov. The members of Cryptocephalus apicalis species group are keyed and illustrated. Significance of the colour pattern polymorphism in taxonomy is discussed.

Nomen Novum

The erebid moth Eublemma pannonica (Freyer, 1840) is a distinctive species of the Pannonian region. The species-group name panonica Freyer, 1840 is an incorrect original spelling what needs a rectification. This spelling has been forgotten until its appearance in the catalogue compiled by Robert W. Poole in 1989 for noctuid names and it is again in use. The other original spelling pannonica Freyer, 1840 is the correct one, what was in general usage until 1989. On the basis of voluminous literature references these spellings are discussed. The name Eublemma panonica ronkayorum Fibiger, Zilli & Yela, 2010 is a junior homonym of Eublemma ronkayorum Fibiger & Hacker, 2002, therefore the replacement name, Eublemma pannonica ronkayi nomen novum is proposed for the junior taxon.

AbstractThree new species of snapping shrimps of the genusAlpheusare described from the Persian Gulf. These belong to theAlpheus edwardsiispecies-group, which is mainly characterized by unarmed orbital hoods and the presence of dorsal and ventral notches on the palm of the major chela.Alphus ankerisp. nov. shows a close affinity toA. pacificusDana, 1852 andA. heronicusBanner & Banner, 1982 bearing no balaeniceps crests in both sexes on the dactylus of the minor chela, and the merus of the major chela of both sexes are unarmed. This species differs from the closely related species by the absence of an overhanging proximal shoulder in the major chela. The other rock crevice inhabiting species,A. mohammadpourisp. nov. is diagnosed by exhibiting sexual dimorphism in its balaeniceps crests and the armed merus of the major chela. These two characters are similar to those recorded for three sandy/rubble dwelling species:A. inopinatusHolthuis & Gottlieb, 1958,A. lobidensDe Haan, 1849 andA. australiensisBanner & Banner, 1982. This new species is distinguishable from these latter species by the shape of the minor chela and colour pattern. A coral inhabiting speciesA. abumusasp. nov. appears to be closely related toA. maindroniCoutière, 1898, showing an armed merus of the major chela and the absence of spine-like seta on the ischia of the third legs. This last new species is easily discriminated fromA. maindroniby longer antennular segments, a markedly concave frontal margin between the rostrum and orbital hood, and a different colour pattern.

In this paper available material of the Elaphe longissima species group from Iran, presented in museum collections or collected by the authors, has been studied. Statistical cluster analyses are applied to this material. Three different taxa (hohenackeri, persica, longissima ssp.) are recognized within this group from Iran. Of three specimens of Elaphe hohenackeri, collected in Iran, two have the "taurica" form of pattern. A comparison with E.hohenackeri from different parts of its range showed that this species is monotypic. The phenetical distance between E.l.persica and non-Iranian E.l.longissma was of similar magnitude as between these two and E.hohenackeri, which motivates a specific rank for persica. Elaphe persica n.comb. is distributed in the Alburz mountains in northern Iran. A morphological description is given on the variable juvenile morph. A recently discovered population of Elaphe longissima in western Iran (Azarbaijan) indicates the occurence of a new diverging morph which differs from E.l.longissima in size, number of ventrals in males, subcaudals in both sexes as well as in some colour pattern.

Colour Morphs

The life history and reproductive ecology of White’s skink, Egernia whitii, was examined in a population in the Australian Capital Territory using both field and genetic studies. Colour pattern polymorphism was evident within the population, with both patterned and plain-back morphs present. Lizards typically took 3 years to reach sexual maturity, with the size at maturity being ~75 mm snout–vent length (SVL) in both sexes. There was an even overall adult sex ratio, although a slight female-bias was evident in plain-back individuals. Sexual dimorphism was evident, with males having longer and wider heads, and females having larger body size. Females generally bred annually, with mating occurring in September–October and parturition in late January–February, although the litter was produced over several days (2–10 days, mean 4 days). Litter size ranged from one to four (mean of 2.5). There was a significant relationship between maternal SVL and both litter size and relative clutch mass, but these trends were not consistent between colour morphs. An inverse relationship between litter size and offspring size (SVL and mass) was found. Comparison of the results with previous investigations of E. whitii indicates substantial geographic variation in life-history traits that is presumably associated with latitudinal variation in climatic conditions.

A gynandromorphic grasshopper produced by double fertilization

Two Sides

An individual of the large grasshopper Valanga irregularis (Walker) which exhibited bilateral gynandromorphism, is described. The entire right side was female, the left side being male. The colour pattern on the two sides was completely different, the male side corresponding to the concolorous phenotype, the female side to the contrasty one. The gonad was an undeveloped ovotestis, the testicular part being XO (2n = 23). There are two obvious explanations of this gynandromorph: (1) that a single XX zygote nucleus gave rise to XX and XO nuclei through loss of an X; in this case we would be dealing with a sex-linked pattern polymorphism, the gene for the contrasty morph being dominant to the concolorous allele; (2) that the gynandromorph arose from a binucleate egg, as a result of double fertilization. Data on the frequency of the morphs in the two sexes, in natural populations, do not support the first hypothesis, and it is concluded that the second one must be correct.

Males And Females

The Neotropical geometrine genus Oospila Warren, 1897 includes seventy-nine species and was revised by Cook & Scoble (1995). The genus is distinctive in having a row of raised abdominal crests, which are composed of specialized, erect, metallic shining scales. This paper focuses on the integrative morphological and molecular delimitation of the smallest Oospila species. The wing patterns and genitalia structures of males and females are illustrated. Cook & Scoble (1995) distinguished 13 species groups within Oospila. We discuss the species of the Oospila flavilimes species group, the O. stigma species group and O. miccularia species group below, and separate the O. arpata species complex into a group of its own. Nine new species and two new subspecies are described in this paper: O. cristae sp. n. from Ecuador, O. falcata sp. n. from French Guiana, O. pallidaria boliviensis subsp. n. from Bolivia, and O. loreenae sp. n. from Bolivia (flavilimes species group), O. ehakernae sp. n. from Costa Rica, O. similiplaga bolarpata subsp. n. from Bolivia (arpata species group), O. brehmi sp. n. and O. bifida sp. n. both from Bolivia, O. moseri sp. n. from Brazil, O. absaloni sp. n. and O. pipa sp. n. both from Ecuador (miccularia species group). Oospila similiplaga (Warren) (stat. nov.) is raised here from synonymy with O. arpata (Schaus) and O. imula (Dognin) from synonymy with O. miccularia (Guenée), respectively. Oospila agnetaforslundae nom. nov. is proposed as a replacement name for Oospila marginata Schaus, 1912 (nec Oospila marginata Warren, 1897), raising it to species rank from synonymy of Oospila permagna (Warren, 1909). With this paper, the number of Neotropical Oospila species is raised to 88.
