Description. See description of Mp. fauroti below. I have not seen the only other known species, Mp. jacominae Deeleman-Reinhold & van Harten, 2001. Monophyly. The most convincing synapomorphy known is the dorsal hinged process on the procursus. Among the taxa included in the cladistic analysis, this was an autapomorphy of Mp. fauroti and the charac- ter was thus not coded. Generic relationships. The inclusion of Micropholcus in the Pholcus-gvou^ of genera appears well sup- ported (char. 12: Pholcus-XY'pt of tarsal comb-hairs, char 64: epigynal 'knob'), but its detailed relation- ships with other genera remain obscure. The arma- ture of the male chelicerae (especially the presence of proximal frontal apophyses; char. 18) reminds strong- ly of some unambiguous Pholcus species, but this may result from convergent evolution. Other characters apparently derived in true Pholcus (and close rela- tives) are absent in Micropholcus (procursus 'knee', uncus, sclerotized epig)mum; chars. 35, 48, 65). Thus, all analyses agree in placing Micropholcus in a 'basal' trichotomy together with Sihala and a clade including all other genera of the Pholcus group. The distinctive modified hair on the tip of the male tro- chanter apophysis (Fig. 95) reminds of New World 'Leptopholcus (fig. 105 in Huber 2000); this is prob- ably convergent. Natural history. The widespread Mp. fauroti is a com- mon house spider in the tropics. It occupies much the same microhabitat as most other synanthropics (edges and corners) bu
