Larvae of Bembidiini (Coleoptera: Carabidae): Subtribes Tachyina and Xystosomina

Vasily V. GREBENNIKOV, David R. MADDISON

Eur. J. Entomol. 97 (2): 223-240, 2000 | DOI: 10.14411/eje.2000.040

Larvae of 13 species of the bembidiine subtribes Tachyina (the genera Tachyta Kirby, Tachys Dejean, Polyderis Motschulsky, Elaphropus Motschulsky, Sphaerotachys G. Müller, Paratachys Casey, Porotachys Netolitzky) and Xystosomina (the genus Mioptachys Bates) were studied. Larvae of all studied taxa are described, diagnosed and illustrated. A key to genera is provided separately for the first- and older-instar larvae. Monophyly and phylogenetic position of the subtribes and genera are discussed on the basis of presumably apomorphic character states of larvae. Based on at least six synapomorphic character states the subtribes Tachyina and Xystosomina appear to form a monophyletic group. On the other hand, there are no synapomorphies to propose a sister-group relationship between Tachyina and Xystosomina within the supertribe Trechitae.

Aestivation in Pieris brassicae (Lepidoptera: Pieridae): Implications for parasitism

Hubert R. SPIETH, Elke SCHWARZER

Eur. J. Entomol. 98 (2): 171-176, 2001 | DOI: 10.14411/eje.2001.032

Only in the southern part of the Iberian Peninsula the large white butterfly Pieris brassicae was recorded to pass the summer in pupal aestivation, induced by long-day photoperiods. It is not clear why this photoperiodic response is regionally restricted. We investigated whether the change of life history in P. brassicae may affect the infestation by parasites. This was done by testing the coincidence of photoperiodic responses in both the host P. brassicae and in its main parasitoid Cotesia glomerata. While the response under short-day conditions was very similar in both species, no summer dormancy of any type was found in the parasitoid at photophases >= 15h and temperatures of 15°-25°C in contrast to 100% aestivation in the host. We suggest that aestivation is a response which allows the host to desynchronise its life cycle from that of its parasitoid. This is effective because parasitoid wasps cannot pass the temporary absence of suitable host stages by a similar developmental rest. C. glomerata is then forced to switch to less adequate host species which diminishes its reproductive success.

Notes on the Palaearctic species of Aulacochthebius, with a description of A. libertarius sp. n. from the Moroccan Anti Atlas (Coleoptera: Hydraenidae)

AGUILERA P., RIBERA I., HERNANDO C.

Eur. J. Entomol. 95 (4): 629-637, 1998

Aulacochthebius libertarius sp. n. is described from the Moroccan Anti Atlas. The aedeagus of A. exaratus (Mulsant) and A. narentinus (Reitter), the two other known Palaearctic species of the genus, are figured, and their similarities discussed. The Palaearctic species of Aulacochthebius do not seem to form a natural group, A. narentinus and A. libertarius sp. n. being more similar to some Ethiopian and Oriental species.

Cephalcia masuttii sp. n. (Hymenoptera: Pamphiliidae), a new web-spinning sawfly living on spruce

BATTISTI A., BOATO A.

Eur. J. Entomol. 95 (2): 251-262, 1998

Cephalcia masuttii sp. n. is described from the SE Alps of Europe, based on morphological, biological, and genetic studies. The larvae feed gregariously on Picea abies. The species has been recorded also from Central Siberia and NE China, where the larvae feed on Picea obovata and Picea koraiensis, respectively. Indications exist that it may be more widely distributed in Europe and northern Asia. The strict gregariousness of larvae of this species is peculiar among spruce feeders of Cephalcia. Morphologically the adults are most similar to Cephalcia alashanica, with which they are compared. An allozyme analysis showed that the populations from Europe and China are quite similar and clearly different from the other species living on spruce. The karyotype of C. masuttii (n = 25) is also described.

Habitat use of the fungivorous beetle Bolitophagus reticulatus (Coleoptera: Tenebrionidae): Effects of basidiocarp size, humidity and competitors

MIDTGAARD F., RUKKE B.A., SVERDRUP-THYGESON A.

Eur. J. Entomol. 95 (4): 559-570, 1998

Habitat use of Bolitophagus reticulatus (L.) (Coleoptera: Tenebrionidae), living in the basidiocarps of Fomes fomentarius (L.) Kickx, was investigated in three forest areas in south-eastern Norway: (1) a continuous, coniferous forest, (2) an agricultural area with mostly deciduous forest islands in a matrix of cultivated land and (3) a homogeneous, old deciduous forest stand. B. reticulatus was almost exclusively found inside dead basidiocarps. The size of the basidiocarp was the most important variable for predicting the probability of B. reticulatus presence in the basidiocarps from all three study areas. Drier basidiocarps had a higher probability of beetle presence than the wetter ones. Basidiocarps situated above the ground level had a higher probability of beetle presence than those close to or on the ground level. In the first study area, the presence of Cisidae was found to reduce the probability of B. reticulatus presence perhaps as a result of competition. The disappearance of beetles from previously inhabited basidiocarps seemed to be due to depletion of resources.

Taxonomic review of the genus Aesalus (Coleoptera: Lucanidae) in the Himalayas

ARAYA K., TANAKA M., BARTOLOZZI L.

Eur. J. Entomol. 95 (3): 407-416, 1998

The genus Aesalus F., 1801 of the family Lucanidae in the Himalayas is reviewed, and a new species, A. saburoi sp. n., is described from Central Nepal. This new species has been confused with A. himalayicus Kurosawa 1985, but differs from the latter mainly by a darker and broader body, and by different shapes of the intercoxal process of the prosternum and of male genitalia. The male of A. himalayicus sensu stricto is described for the first time and the male genitalia are illustrated. A key to the members of the genus Aesalus from the Himalayas is provided.

Genetic variation among European populations of Bombus pascuorum (Hymenoptera: Apidae) from mitochondrial DNA sequence data

PIROUNAKIS K., KOULIANOS S., SCHMID-HEMPEL P.

Eur. J. Entomol. 95 (1): 27-33, 1998

Taxonomists have described chromatic and morphological variation for a number of European bumble bee species, although molecular studies have so far failed to find significant differentiation. We investigated the genetic variation of Bombus pascuorum from 13 locations by sequencing a fragment of the mitochondrial cytochrome b gene. We find considerably more variation than in published COII sequences for B. terrestris. The DNA sequences from these bees suggest that a difference exists between areas north and south of the Alps, and that the bees within these two areas are very similar over large areas. Therefore, mitochondrial cytochrome b sequences may be able to reveal geographic subdivision in B. pascuorum across the Alps.

The Pentatomomorpha (Hemiptera: Heteroptera): an annotated outline of its systematics history

SCHAEFER C.W.

Eur. J. Entomol. 90 (2): 105-122, 1993

A brief history of the systematic concept ''Pentatomomorpha'' is outlined. This infraorder of the hemipteran suborder Heteroptera comprises five superfamilies, under either of two arrangements. Under the first: Aradoidea, Pentatomoidea, Coreoidea, Pyrrhocoroidea, and Lygaeoidea; under the second: Aradoidea, Pentatomoidea, Coreoidea (including Coreoidea, Pyrrhocoroidea, and part of Lygaeoidea of the first arrangement), Idiostoloidea, and Piesmatoidea (these two removed from the Lygaeoidea of the first arrangement). The infraorder Cimicomorpha is probably the sister group of Pentatomomorpha, and Leptopodomorpha may be the sister group of both those two infraorders. The ancestor of the Coreoidea, Pyrrhocoroidea (first arrangement), and perhaps Pentatomoidea may have been lygaeoid-like. The taxonomic and phylogenetic position of the Aradoidea is obscure. The classification (to family level) of the Pentatomomorpha is tabulated.

Maternal care in Pygoplatys bugs (Heteroptera: Tessaratomidae)

GOGALA M., YONG H.-S., BRUEHL C.

Eur. J. Entomol. 95 (2): 311-315, 1998

Cases of maternal care and egg guarding were observed and photographed in bugs of the family Tessaratomidae. Females of one still undescribed species of Pygoplatys from Doi Inthanon, Thailand, and of Pygoplatys acutus from Borneo are carrying their young larvae on the venter. The egg guarding was also observed in Pygoplatys acutus from Kepong, Peninsular Malaysia. It seems, that maternal care is a characteristic behavior in bugs of the genus Pygoplatys.

Prediuresis in female Phlebotomus sandflies (Diptera: Psychodidae)

SADLOVA J., REISHIG J., VOLF P.

Eur. J. Entomol. 95 (4): 643-647, 1998

Sandfly females, while feeding on the host, excrete urine to concentrate proteins of the bloodmeal and restore weight and water balance. This process, analogous to prediuresis in mosquitoes, was observed in 100% of Phlebotomus papatasi (Scopoli) and 85% of P. duboscqi Neveu-Lemaire females studied. Individual females, however, differed in duration of prediuresis and in the number of ejected urine droplets. In both species the prediuresis generally started 1-2 min after the commencement of feeding and the variation in urine production was positively correlated with the length of feeding. The first one or two droplets were opaque whitish while the remaining ones were clear. Erythrocytes were found sporadically in first droplets of some females. Representative prediuresis in P. duboscqi included 27 droplets, i.e., about 325 nl urine in total, ejected during 8 min of feeding. The study revealed prediuresis in P. papatasi and P. duboscqi as a regular physiological process which may have consequences in transmission of infective diseases.

A new subgenus and two new species of Sphaericus (Coleoptera: Ptinidae) from Western Australia

BELLES X.

Eur. J. Entomol. 95 (2): 263-268, 1998

A new subgenus Leasphaericus (of Sphaericus) with two new species, S. (L.) flavipennis and S. (L.) diversevillosus, are described from North West Cape and Barrow Island, in Western Australia. With the exception of one anthropophilous and paracosmopolitan species, the genus Sphaericus had been recorded only from the southern Palaearctic area. The discovery of Australian autochthonous Sphaericus suggests that this genus may be more diversified in other areas, namely in Africa.

A redefinition of Blissia with description of a new species from northwestern Canada (Collembola: Isotomidae)

FJELLBERG A., POTAPOV M.B.

Eur. J. Entomol. 95 (1): 87-91, 1998

The formerly monotypic genus Blissia is given a wider definition, in order to include a second new species, Blissia robusta, from the Ogilvie Mts, Yukon Territory, northwestern Canada. Some additional characters separating the genera Blissia and Tetracanthella are described.

Differential parasitisation of adult and pre-imaginal Coccinella septempunctata (Coleoptera: Coccinellidae) by Dinocampus coccinellae (Hymenoptera: Braconidae)

GEOGHEGAN I.E., MAJERUS T.M.O., MAJERUS M.E.N.

Eur. J. Entomol. 95 (4): 571-579, 1998

The parasitoid wasp Dinocampus coccinellae has been reported to parasitise adult, pupal and larval coccinellids. Field samples of larvae and pupae of Coccinella septempunctata, collected over 13 years in Britain, have failed to reveal any infected pre-imaginal individuals. The parasitisation rates of D. coccinellae into pre-imaginal and adult C. septempunctata were assessed in both choice and no-choice tests. Observations and test results revealed that British D. coccinellae have a strong preference to oviposit in adult coccinellids rather than larvae or pupae. This preference decreases as wasps age if denied oviposition opportunities.

A revision of the genus Microtrichalus from the Philippines (Coleoptera: Lycidae)

BOCAK L.

Eur. J. Entomol. 95 (3): 417-428, 1998

The species of the genus Microtrichalus Pic, 1921 represented in the Philippines are revised. Six species are placed in the genus; in addition to M. basipennis (Pic, 1926), two species are described as new (M. retractus sp. n. and M. salvani sp. n., both from Mindanao), and three species are transferred from the genus Trichalus Waterhouse, 1877: M. bakeri (Kleine, 1929) comb. n., M. costilis (Kleine, 1926) comb. n. and M. communis (Waterhouse, 1879) comb. n. A key to the six Philippine Microtrichalus species and illustrations of their important diagnostic characters are provided. Trichalus nigricauda Bourgeois, 1886 and T. longicollis Bourgeois, 1883 are transferred to the genus Leptotrichalus Kleine, 1925. Leptotrichalus mindorosus Pic, 1925 is proposed to be a junior subjective synonym of Leptotrichalus longicollis (Bourgeois, 1883).

Population ecology and clone dynamics of the galling aphid Geoica wertheimae (Sternorrhyncha: Pemphigidae: Fordinae)

WOOL D., BEN-ZVI O.

Eur. J. Entomol. 95 (4): 509-518, 1998

Geoica wertheimae induces spherical galls on its primary host, Pistacia palaestina (Anacardiaceae). We studied the temporal changes in gall size and aphid clone size, as well as gall distribution and abundance on marked trees during two consecutive years. The density of galls (per shoot and per leaf) was low during the study period, and gall distribution was clumped. Gall abundance varied greatly among trees, but gall abundance and tree budburst phenology were uncorrelated. Galls increased eight-fold in volume during the season, in parallel with the increase in aphid clone size, from one individual to several hundred aphids per gall. The trigger for the induction of the alate morph in the galls in late summer seems to be an abrupt change in aphid density within the galls, which occurs when aphid reproductive rate exceeds the rate of change in gall internal surface area.
Two species of Lepidopterous larvae were present in about one-third of the galls. They occasionally destroyed the aphid clone, but many aphids often remained alive. However, the volume of parasitized galls was significantly smaller than that of unparasitized galls, illustrating the dependence of gall size on aphid clone size.
