 issued from : P. Koomen & J. C. von Vaupel Klein in Crustaceana, 1997, 70 (5). [p.530, Fig.1, a]. Abbreviations used for integumental organs Pictogram coding), studied by differential interference contrast microscope/yy (DIC) and scanning electron microscope/y (SEM). SLIT = regular slit-shaped glandular pore. CONC = (partly) concealed slit-shaped glandular pore. CLO = large closing-flap glandular pore. TUB = tubular glandular pore. PIT = pit-sensillum. PEG = peg-sensillum. HAIR = hair-sensillum. SPIN = spine-sensillum and/or spinular pore. CIRC = circular pore. URN = urn-shaped glandular pore. BUT = button-shaped pore. UNC = integumental organ of uncertain nature. Possibly, someofthe PITs, as oberved by DIC, may be damaged PEGs (see in KOOmen, 1992). For this reason, only in in situ drawings of specified specimens (e.g. figs 1-6) distinction has been made between PITs and PEGs (as observed by DIC). In overall schemes such as the present fig.7, both types of integumental organs have provisionally been represented by PEG symbols. Nota: The slit-shaped glandular pores are small (external opemning diameter 0.001 mm diameter or less). By DIC a small circular structure with a central dot is visible, connected to a canal. These structures have been called SLITs see fig.1a, b), because fhey occupy the same site as the SLITs established in Euchirella mssinensis (except for some intraspecific differences), and may thus be expected to be homologous of last-mentioned species. Peg-sensilla (PEG), long and slender (length up to 0.022 mm) (see fig. 1c, d), sometimes difficult to discriminate from small sensilla. The shape of the canal through the inteegument has been considered decisive (see Vaupel Klein, 1992c ; Koomen, 1992). Most PEGs are situated in depressions of the integument, while their basal discs meet the surface of the integument at an angle (see Pl. 1c, 1d). Spine-sensilla or spinular pore (SPIN), rather long and slender in comparison with those of Euchirella messinensis, and in fact come close to the PEGs of this species. However, distinction between SPINs and PEGs of P. obesa is possible, because a SPIN is shorter and stouter than the average PEG of the same species, an dits basal disc is in line with the surface of the integument. Circular integumental structure (TUB), resembling a disc (0.0035 mm) with a cenrtral knob (see Pl. 1g).
