Obrimus uichancoi

Males of Obrimus uichancoi have not been described. In this species, too, the slits in the metasternum typical of the genus are very narrow and barely recognizable. Compared to the two other species of Obrimus for which females are known, Obrimus bicolanus and Obrimus bufo, this species is less spiny and on average somewhat smaller. The central spines on terga I to VI of the abdomen are either completely missing or are only recognizable as paired, small tubercles. The medial spines on the mesonotum (median mesonotals) are either completely missing or very indistinct, as in the females collected in Bay-Yo in the Mountain Province. The females reach lengths of 8.5 to 10.0 centimetres (3.3 to 3.9 in), although the specimens from the Ifugao province examined are somewhat larger on average. The coloration of the specimen in life is known only from one female from Banaue in the Ifugao province. This specimen has a pure green base color with little brown and light patterning.

The distribution area of the species extends across the north of the island of Luzon. The type locality is Ripang in the province of Apayao. The geographic coordinates are given as 17°48’N 121°90’E. Other localities are in Bay-Yo on the border of the Mountain Province and the province of Nueva Vizcaya, where it has been found in both provinces, as well as in the province of Ifugao, in the Cordillera Central mountain range, and in Banaue. The specimens have been found at altitudes between 450 and 1,300 metres (1,480 and 4,270 ft). Another locality is in Los Banos in the province of Laguna. A very young male, identified by the first describers of this species, comes from southern Luzon, more precisely from Barangay Binay in the municipality of San Narciso in the province of Quezon., Since only female animals have been found apart from this male, it is assumed that the species reproduces purely parthenogenetically, at least locally.
