Biospeologica sovietica. XLIX. The first troglobite representative of Trechinae (Coleoptera, Carabidae) in Ciscaucasia., 1972, Ljovuschkin S. I.

During a recent exploration of caves in western Ciscaucasia there was collected, among others, a new species representing a new genus of Trechini (Coleoptera, Caraboidea), the description of which is given here; it has been named Birsteiniotrechus ciscaucasiens n.gen., n.sp., in memory of Prof. J.A. Birstein, famous Soviet biospeleologist, the founder and promotor of the "Biospeologica sovietica" series who passed away recently (cf. I.J.S., 4, part.2). The interest of Birsteiniotrechus lies in the fact that, until now no troglobite or endemic species of Trechini was known from the Ciscaucasian mountains; this genus belongs to the phyletic series of Neotrechus and is nearly allied to Troglocimmerites, but differs from it by its labial characters.

The ecology of a predaceous troglobitic beetle, Neaphaenops tellkampfii (Coleoptera: Carabidae, Trechinae). I Seasonality of food input and early life history stages., 1975, Kane Thomas C. , Norton Russell M. , Poulson L. Thomas

The adaptations in the life history of the Carabid beetle Neaphaenops tellkampfii has been investigated in respect to seasonal food input. The following characters have been studied: copulations, egg production, larvae and pupae.

The ecology of a predaceous troglobitic beetle, Neaphaenops tellkampfii (Coleoptera: Carabidae, Trechinae). II Adult seasonality, feeding and recruitment., 1975, Kane Thomas C. , Norton Russell M. , Poulson Thomas L.

In deep cave areas with loose substrate and sufficient moisture, the life history of Neaphaenops tellkampfii (Coleoptera: Carabidae, Trechinae) is synchronized with the seasonal pattern of its primary food sources, the eggs and first instar nymphs of the cave cricket Hadenoecus subterraneus (Orthoptera Gryllacridoidea, Rhaphidophoridae). Neaphaenops reproduction coincides with an order of magnitude increase in Hadenoecus egg input in the spring. Our 46 observations of predation by Neaphaenops suggest some switching to other cave animals as cricket egg and first instar nymph densities decrease during the summer. Neaphaenops life history in areas of Hadenoecus egg input is as follows: (1) female Neaphaenops reach maximum fecundity at the time of the maximum density of fìrst instar Hadenoecus nymphs; (2) early instar Neaphaenops larvae appear in late summer and fall; (3) last instar Neaphaenops larvae appear in early spring and pupation occurs shortly thereafter; (4) lightly coloured teneral adults emerge two to three months later, a time consistent with laboratory estimates of the length of the pupal stage. Seasonal changes in sex ratio due to differential mortality appear to be consistent with this seasonal pattern. A comparison of Neaphaenops with two other species of carabid cricket egg predators suggests the importance of seasonal food abundance in determining life history seasonality. Darlingtonea kentuckensis has a food resource pattern which appears identical to that of Neaphaenops, and the life history seasonality is also parallel. Rhadine subterranea, however, seems to have a much more equitable food input throughout the year, and appears to have an aseasonal life history.

The sensoral outfit of subterranean Trechinae. II. Ultrastructure of the Elytral trichobothria., 1978, Juberthie Christian, Piquemal Francoise

The ultrastructure of trichobothria (Tm2, Tr2, Tr4) of the elytra has been studied in the troglobitic Coleoptera Geotrechus vulcanus and Aphaenops cerberus. Two bipolar neurons innervate these trichobothria. The first ends at the level of the hair base, and its distal segment contains a tubular body, characteristic of mechanoreceptive bristles. The other does not possess a tubular body, and its distal segment ends in the bristle canal; its function is unknown. The trichobothria possess one glial enveloping cell, one trichogen cell, and one tormogen cell; the latter two show an apical, common, large, receptor lymph cavity. The small trichobothria are innervated by a large mechanoreceptor neuron, and by 4 smaller neurons; its function is unknown. The trichobothria of blind Trechinae are highly specialized. A cuticular cup enshrines the hair base; hair and cup move together. The large amplitude swaying movements of the hair are controlled by a spongious tissue around the cup. The trichobothrià of Trechinae and Periplaneta have the same type of cuticular dome-shaped structure, and differ from trichobothria that arise from a cavity in the cuticle.
