Folioquinpes mangalis Fiers & Rutledge, 1990 

Original description.

Fiers and Rutledge (1990): 122-124; fig. 9.

Type locality.

Papua New Guinea, Capital District, Motupore Island; mangrove along northern shore; algae on pneumatophores.

Body length.

600 μm (♀), 400 μm (♂) [ Fiers and Rutledge 1990].


Folioquinpes mangalis  differs from its congeners in the bilaterally incised cephalothorax and the more strongly developed P5 ♀ endopodal lobe which bears only two setae. The dense spinular ornamentation on the anterior surface of leg 5 has not been documented in other species of the genus. The species is similar to P. pseudomangalis  sp. n. in the strongly depressed body, the distinct pleural extensions on the urosomites, the 4-segmented female antennule, the lack of the inner seta on P4 exp-2 (and P3 exp-2 but see below) and the presence of only two inner setae on P3 enp-2.

Fiers and Rutledge (1990) found two specimens with an inner seta on P3 exp-2; the absence of this seta appears to represent the normal condition. They also figured only two outer spines on P1 exp-2 (their figure 9g) but mentioned three in the text, which is here regarded as the correct condition.

Folioquinpes mangalis  has been found on pneumatophores of mangrove trees along the southern (type locality) and northern coast (Sepik River delta) of Papua New Guinea and on Spartina alterniflora  stems from marshes in Cocodrie, Louisiana ( Fiers and Rutledge 1990; Rutledge and Fleeger 1993). It was subsequently found in samples of decaying leaves and sediment, from a Rhizophora apiculata  -dominated mangrove forest bordering the Sungai Merbok estuary in north-western peninsular Malaysia ( Gee and Somerfield 1997; Somerfield et al. 1998). Kim (2013) recently identified two specimens from Jeju Island, Korea as F. mangalis  but this material is believed to represent a different species (see below).
