The pseudepiphallic parameres, the main clasper devices in crickets, are remarkable in Luzarinae and usually divided in a pair of dorsal sclerites (pseudepiphallic parameres, 2--PsP2) and a ventral one (pseudepiphallic parameres, 1--PsP1).
This sclerite was identifiable as a distal apophysis because of its position on the apical part of the tegulum and because of its dual connection through flexible membranes with the apical part of tegulum and the basal part of embolus.
Four types of epibiotic and endocuticular bacteria on sclerites and in body mantle cuticle have been demonstrated as symbionts in H.
The data at hand, if interpreted uncritically, would thus suggest that mating plugs in Nephilengys are usually formed by the terminal two sclerites as in most other nephilids (Kuntner 2005, 2007; Kuntner et al.
Variation in both sclerite number and shape has been noted by a few authors, depending on the position of rods in a suction cup (Fryer 1959; Rushton-Mellor and Boxshall 1994; Avenant-Oldewage and Oldewage 1995).
A low, semi-ring-shaped mesal and dorsal (posterior) wall of the antennal sclerite entire, whereas the higher ventral (anterior) and lateral wall fragmented into seven sclerites, four of them crescent-shaped and distinctly delimited, the fifth forming basis of antennifer, an indistinctly delimited sixth represented by a sclerotization within the basi-antennal membrane (a diffused prescapite?
Patellal apophysis broad, dorsally concave; RTA more than half the tibial length, with distinctly extending distal end; lateral tibial apophysis absent; cymbial furrow less than 1/3 of cymbial length; conductor short, basal lamella indistinct, dorsal apophysis about the same size as conductor; median apophysis small, spoon-shaped, without free standing anterior edge, arising posteriorly; embolus short, filiform, prolateral in origin, thread originating near middle of tegular sclerite (Figs.
Ventral arch (VA) articulating with ventral margin of mouth hook, sclerotized, two foramens, anterior margin with 20-24 denticles, posterior margin V-shaped; epistomal sclerite (ES) bilobed, welded to both parastomal bars (PB), all C-shaped; parastomal bars posteriorly fused with pharyngeal sclerites.
Andersen (1995b) diagnosed the relationship between Limnometra and Tenagogonus based on the relatively long fourth antennal segment, the predominantly pale pronotum, and the convex plate-shaped accessory scent gland sclerite, while Andersen and Weir (1997) distinguished between Limnometra + Tenagogonus and the Australian genus Tenagogerris on basis of the relatively short rostrum in Tenagogerris.
There is a massive, but simple sclerite in a distal position (DMS) which serves as a functional conductor and is often adorned with additional sclerotizations in medioectal position (MES) (Figs.
Thorax: Cervical sclerite flat and dull, with lateral indentation and small anterolateral vertical carina; proepisternum with a few long marginal ventral setae on posterior 1/2; katepisternum with double row of thin black setae, anterior row with only 5 setae, barely overlapping with lower end of posterior row; scutellum with 1 pair of marginal setae only, 1 small to minute seta between postalar and dorsocentral setae.
Terms for the endosomal sclerites in the Bothriomirini presented in Figure 5 are explained in the separate paper (Wolski and Gorczyca, 2012).
