Description ( Figs 160–165 View Figure 160 View Figure 161 View Figure 162 View Figure 163 View Figure 164 View Figure 165 )

Adult female maximum 15.8 × 7.0 mm, cephalothorax 3.37 mm wide; smallest female with marsupium with cephalothorax 2.43 mm wide. Males maximum 14.0 × 5.9 mm. Adults with 20–25 ommatidia.

Large adult female cephalothorax width 2.43– 3.34 mm, e.g. female with marsupium 13.5 × 7.2 mm, cephalothorax 3.03 mm, male 14.0 × 5.9 mm. Smallest female with marsupium has a cephalothorax width of 2.43 mm and 21/21 ommatidia.

Endoantennal conglobation ability. Dorsum dark red with black and yellow patches. Cephalothorax behind cephalic shield with a deep furrow, lateral parts of which extend behind the eyes. Lateral parts of transverse furrow distally enlarged, whereas the median portion is partly covered by upper margin of frontal shield. Females with marsupium have four transverse rows of three cotyledons each. Appendages almost identical with those of Globo. falconensis .

In contrast, despite the larger size of the animal, ventral scale-fields present only on pereiopods 1 and 2 (this was observed on all available male specimens). Ventral setae of these legs curved, whereas they are straight in Globopactes falconensis .

Adults have the lateral margins of coxal plates 2 and 3 strongly concave, forming a cleft in which the following coxal plates fit when conglobating.

Mancas 2.31−2.69 × 1.31−1.38 mm, seven ommatidia each. Mancas are grey, without red pigment; tergites are strongly hirsute, and coxal plates 2 and 3 are convex. The conspecificity of mancas and adults was proven by rearing several females with marsupium until hatching of the mancas.

Remark

The specimens are conspecific with those examined by Vandel (1952), who referred to them as Sphaeroniscus senex ( Budde-Lund, 1893) . In the Vandel collection, a tube with one female specimen is labelled Scleropactes senex . A re-examination of the holotype of Sphaeroniscus granulatus showed that it does not differ from the recently collected specimens of the same size, either in morphology or coloration, remains of which are preserved in the holotype. Regarding the geographical closeness, it is very probable that all these specimens belong to the same species. In contrast, the type specimens of Scleropactes senex Budde-Lund, 1893 show strong differences, and were collected in a geographically distant area (see above).

Reproduction

Three females with marsupium had 19 eggs (with embryos), 31 eggs (with embryos), and 23 eggs (undeveloped?), respectively.

Habitat

Cloud forest, on the northern slope of the coastal cordillera. The specimens were found under stones in the forest and beside the road. When disturbed, they either appressed to the surface of the stone or conglobated.

Remark

Richardson (1914) reported two specimens from Colombia (Cauca, Puerto de los Pobres , altitude 800 m). Taking into consideration the known localities of the Globopactes species , it seems unlikely that these two specimens actually are G. granulatus .
