subchelate

subchelate
An appendage in which the dactylus is shorter and less robust than the propodus or vice versa [Ingle, 1980].
Claw-like, formed of transverse end of propodus and opposing dactylus (cf. chelate) [Poore, 2004].
Having the ability to grasp by folding together two adjacent podomeres of a limb [Hobbs and Jass, 1988].
Provided with subchela [McLaughlin, 1980].
Provided with subchelae [Moore and McCormick, 1969].
The state of a limb in which the dactylus can be closed so as to bite against the propodus. Unlike the case in a true chela, a fixed finger is not developed and the dactylus bites either against an enlarged edge of the propodus or against projecting spines (Fig. 23B, C) [Warner, 1977].
(Order Isopoda):
Having a subchela, foming a pincerlike structure, especially by the dactylus folding back on the propodus [Kensley and Schotte, 1989].
(Order Isopoda):
Having a subchela; forming a pincerlike structure by the dactylus folding back on the propodus [Wetzer et al. 1997].
