On the extant type material of Cardisoma hirtipes Dana, 1851, and Cardisoma obesum Dana, 1851 (Crustacea: Brachyura: Gecarcinidae)

Abstract

Two boxes in the U.S. National Museum of Natural History, Smithsonian Institution, were found to contain the dried type material of the land crabs Cardisoma hirtipes Dana, 1851, and Cardisoma obesum Dana, 1851 (Gecarcinidae). Th e types of the common Pacifi c land crab, C. hirtipes were believed to have been lost and a neotype had been designated in earlier revisions. Cardisoma obesum Dana, 1851 is currently regarded as a junior subjective synonym of Cardisoma carnifex (Herbst, 1796).

The diversity and distribution of Gecarcinidae MacLeay, 1838 (Crustacea: Decapoda: Brachyura), a potential land crab as a valuable food resource, in Indonesia

“…Other colorful species from Southeast Asia have exported to other regions such as Japan, China and Europe as pet animal. Notably, three Indonesian species, namely Gecarcoidea lalandii, Tuerkayana humei and Tuerkayana magnum has been common commodity exported to Japan, China and Europe [18]. Apparently, those species have been collected from southern of Java Island.…”

“…There are 28 species worldwide, comprises of genera Cardisoma [9] with five species, Discoplax [12] with three species, Epigrapsus [6] with two species, Gecarcinus [10] with four species, Gecarcoidea [13] with three species, Johngarthia [26] with six species, and Tuerkayana [6] with five species [27]. In Southeast Asia, there are six recorded species, i.e., Cardisoma armatum, Cardisoma carnifex, Discoplax longipes, Gecarcoidea lalandii, Tuerkayana hirtipes, and Tuerkayana rotundum [3,18]. However, hitherto there is no record of the species richness of this land crab in Indonesia although it is known as 1275 (2023) 012038 IOP Publishing doi:10.1088/1755-1315/1275/1/012038 2 one of the countries that has megabiodiversity.…”
