狼蛛,蟹蛛和跳蛛

狼蛛、蟹蛛和跳蛛分别是蜘蛛目中三个科的蜘蛛的通称。这三类蜘蛛包括了我们日常见到的游猎型蜘蛛的大部分种类,它们在帮助人类消灭害虫中所起作用也较大,所以作为动物学教学中的例子加以介绍。 (一)狼蛛狼蛛在地面或植物上疾驰,凶狠如狼,故名。体长3-25毫米,但多数种类在5-8毫米间。体色多黄褐色,不鲜艳。8眼,排成三列。前列4个小眼,中、后两列各2个眼,较大;后列两眼的间距稍大于中列两眼的间距(图1左)。卵袋扁球形,由两片半圆形丝膜缝合而成。卵袋挂在母蛛腹部后端的纺器上,由母蛛随身携带。幼蛛孵出后不分散,而是爬伏在母蛛腹部

A jumping spider that lays eggs like an insect

The South East Asian salticid, Asemonea tenuipes, lay its eggs like an insect: as individuated capsules in geometrically precise rows. The occurrence of this behaviour is described in a population from Thailand that lays eggs on the underside of mango tree (Mangifera indica) leaves. The rows were vertically arranged at a 90° angle that was parallel to, and varied in relation to the angle of the central leaf rib, indicating that the rib serves as the primary visual cue for orienting the row. Analysis of within-egg row symmetry found evidence that micro-topography – in particular, vertical ‘stepping’ produced by leaf sub-ribs – of the leaf surface plane was responsible for 97% of variability in the relative symmetry of egg placement. Three strategies were identified: (1) crossing the sub-rib and producing localized asymmetry in the egg row; (2) introducing a gap at the sub-rib to maintain symmetry; and (3) ‘compressing’ the egg row into the gap between sub-ribs. The incidence of asymmetry showed a highly significant linear relationship with egg load. It is hypothesized that the use of rows probably represents a solution to the problem of how to surveil temporally staggered clutches of eggs and newly hatched spiderlings simultaneously.     

Five new species of Triotemnus (Coleoptera, Curculionidae, Scolytinae) from Morocco and Yemen

Fivenew species of the genus Triotemnus from Morocco and Yemen are described. Triotemnus is a new genus of Scolytinae for the Yemen region. External morphology of the new species and all morphologically related species of the genus were studied. While the new species from Morocco are morphologically similar to the known species from the corresponding region, all three newly described species from Yemen, mainly two of them living in Socotra, are morphologically very different from all other known species of the genus. Geographical distribution and the probability of endemicity are discussed.     

Tripterygiid Fishes of New Caledonia, with Zoogeographical Remarks

The Tripterygiidae of New Caledonia are revised and their zoogeographical relationships discussed. A total of 27 species is recognized from the territory; three species are recorded from New Caledonia for the first time [Enneapterygius howensis Fricke, 1997; Enneapterygius rhabdotus Fricke, 1994; Helcogramma trigloides (Bleeker, 1858)]. From Grande Terre, 26 species are known, with four species recorded for the first time. Seven species occur at the Ile des Pins (all new records); from the Chesterfield Islands, six species of tripterygiid fishes have been recorded; and from the Loyalty Islands, 17 species are known, with three species recorded from the island group for the first time: 15 species from Ouvéa, 11 species from Lifou (eight new records) and five species from Maré (three new records).     

A revision of the tribe Plectrothripini of fungus-feeding Thysanoptera (Phlaeothripidae: Phlaeothripinae)

Abstract The tribe Plectrothripini is redefined with examination of its systematic relationships. Keys are provided to the ten genera and forty-seven species in this tribe; one genus and eighteen species are newly described; one genus and two species are newly synonymized; two genera, Chiridothrips and Eurytrichothrips , are here removed from this tribe. The species of the tribe occur throughout the tropical and subtropical regions of the world; seventeen species are recorded from the Oriental Region, seventeen species from the Neotropical Region, ten species from the Afrotropical Region, two from Australia and one from the Pacific. They seem to be fungus-feeders, being found mainly under the bark of trees or on dead branches.     

Chromodorid opisthobranch Mollusca from East Africa and the tropical West Pacific

Six species of Hypselodoris and three species of Chromodoris axe described from the coast of East Africa. Three species of Hypselodoris and one species of Chromodoris are new species. Two species of Chromodoris from the tropical West Pacific are also described. The eleven species fall into three groups of similarly coloured species.
Hypselodoris nigrostriata and a new species of Hypselodoris are compared with H. infucata, H. festiva, H. obscura and two unnamed species from the literature. It is concluded that all these are distinct species.
H. nigrolineata and two new species, are compared with H. lineata and H. hilaris and all are considered distinct.
H. regina, Chromodoris quadricolor, C. africana, C. elisabethina, C. magnified and a new species of Chromodoris, are compared with C. westraliensis and two unnamed species from the literature. All these species are considered distinct.
All other names for forms falling into these three colour groups are considered synonyms of one or other of the above named species. Full synonymies are given.     

The Chromodorididae (Opisthobranchia: Mollusca) of the Indo-West Pacific: Chromodoris splendida, C. aspersa and Hypselodoris placida colour groups

Eleven species of Chromodoris, two species of Hypselodoris, three species of Mexichromis and one species of Noumea are described from the Indo-West Pacific, of which four species of Chromodoris and one of Mexichromis are new species. All species have a colour pattern dominated by red, purple or black spots. All previously described species with similar colour patterns, from both the Indo-West Pacific and other regions, are discussed.     

Marine biodiversity of Costa Rica: Crustacea: Infraorder Anomura

The anomuran crabs are among the best known crustacean groups from the Pacific coast. However, this group is poorly known from the Caribbean coast of Costa Rica. In this compilation based on the literature and the collection at the Zoology Museum, Biology School, University of Costa Rica, we report the presence of 114 species of the Infraorder Anomura for Costa Rica, 20 species from the Caribbean, 96 species from the Pacific (two are present on both coasts). Twenty-nine species are new reports for Costa Rica, 15 from the Caribbean coast (74% of the total of species from that coast) and 14 from the Pacific (15% of the total from the Pacific). The range often species is extended to Costa Rica, siete from the Caribbean and three from the Pacific. Six species are reported for the first time from Cocos Island, where there are also four endemic species.     

Flavonoid distribution patterns in Leucanthemum and related species from North Africa

Flavonoid data is reported for 16 species including eight species of Leucanthemum from North Africa, four from Europe and related species in the Chrysanthemum-Leucanthemum complex. Flavonols, especially quercetin, isorhaamnetin, kaempferol, patuletin and spinacetin, are predominant in the North African species. Flavones, which are common in Leucanthemum species in Europe, are of very rare occurrence in the North African species. The relationship of the species based on the distribution of flavonoid glycosides and aglycones from the ray florets is discussed.
