Grey-striped Francolin Pternistis griseostriatus: specimens, distribution and morphometries Michael S. L. Millf,b, Pedro Vaz Pintoc and Scott Habed Le Francolin a bandes grises Pternistis gi'iseostriatus : specimens, distribution et mensurations. Le Francolin a bandes grises Pternistis griseostriatus est une espece endemique a l'Angola et peu etudiee. Auparavant il n’etait connu que de 25 specimens et semblait comprendre deux populations distinctes. Les auteurs resument les informations sur 32 specimens et leurs propres observations recentes, et presentent une carte de distribution des localites connues. Ces donnees montrent que Fespece possede une repartition plus etendue qu'on ne le pensait precedemment, etant continue le long de l’escarpement de l’Angola, a environ 08-l4°S. Les mensurations des specimens des trois collections les plus importantes sont presentees. La comparaison du poids et de la taille des deux sexes revele que les males sont bien plus grands que les femelles. Les donnees collectees ne confirment pas l’hypothese que les populations meridionales sont plus grandes que celles du nord, comme il etait postule auparavant. Summary. Grey-striped Francolin Pternistis griseostriatus is a poorly studied Angolan endemic. Previously it was known from 25 specimens, and appeared to comprise two distinct populations. Here we summarise information on 32 specimens and our own recent observations, and map the distribution of known localities. These data show that the species has a continuous range along the Angolan escarpment, at c.08-l4°S, and a wider distribution than previously thought. We also summarise morphometric data for specimens in the three largest museum holdings, and compare male and female mass and size, demonstrating that males are significantly larger than females. However, our data do not support the hypothesis that southern populations are larger than northern populations, as was previously postulated. G rey-striped Francolin Pternistis griseostriatus quarter of the 20th century (Dean 2000, Ryan is a little-known, Near Threatened, Angolan et al. 2004). Since 2002 some additional data endemic that occurs in densely vegetated habitats have improved our knowledge of the species' associated with the Angolan escarpment (Pinto vocalisations, local abundance, distribution and 1983, Urban et al. 1986, Dean 2000, BirdLife behaviour (Vaz Pinto 2002, Ryan et al. 2004, International 2009) (Figs. la-b).

However, recent records from LBSC. Thus a total of 32 specimens are currently various localities between Gabela and Gungo traceable, excluding the destroyed Lisbon skin and demonstrate that the species occurs continuously the missing skins from BMNH and LBSC. There along the scarp at least as far as the Kwanza Sul are no specimens in other museums contacted: the / Benguela provincial border (Mills & Dean Museu Zoologico da Universidade de Coimbra 2007, Mills 2010). The r.l40-km stretch of scarp (Carreira 1990), the Museum fur Naturkunde, between Gungo and the Bongo River has not Berlin, the' Museu Nacional de Historia Natural, been surveyed, but the species probably occurs wherever suitable habitat exists, especially in the Canjala / Egito area, where several other scarp endemics have been collected (Mills & Dean 2007). In September 2006 W. Brock purchased a live Grey-striped Francolin on the roadside near Canjala, which had been acquired in gallery forest nearby (PVP). Recent records from near Quitexe on the Kwanza Norte / Uige provincial border and in the Namba Mountains of southern Kwanza Sul (Mills et al. submitted) extend the known range north and east (Fig. 2); These records reveal that the species has a range of c.45,000 km2 (Mills 2010), larger than the 17,300 km: estimated by BirdLife International (2009). Most of the localities from which records are available are sited on or adjacent to the Angolan scarp, and range in altitude from sea level to 1,150 m. The only exceptions are Pungo Andongo, east of the scarp on the Angolan plateau, the high Namba Mountains in the Angolan central highlands, from where there is a record at over Figure 2.

One-tailed student t-tests (Zar 1999) were used to test whether males are, on average, larger and heavier than females, as is the case Table 3), although northern males and all birds in many other members ol the genus (Hockey combined were significantly heavier than their et al. 2003). We also tested whether southern southern counterparts, contra the suggestion of populations (south of 12°S) are larger and heavier Pinto (1983).
