“…The lizard fauna in Pakistan belongs to eight families naming; Agamidae, Chamaeleonidae, Eublepharidae, Gekkonidae, Lacertidae Scincidae, Uromastycidae, and Varanidae (Khan, 2000). The number shows a steady increase from (Minton, 1962(Minton, , 1966 65 species, Merten's (1969), Khan (1980), to Khan (1999), 101 species and subspecies, belonging to 35 genera (Khan, 1999) Ptyodactylus which is the only recorded species of this genus from Pakistan, which was recorded from western Kirthar Range in northwestern Sindh in 1876 by Blanford, since there is no subsequent record of this species from Pakistan, largely because of the absence of collection from this area. The Northern Areas of Pakistan are at the boundary between the Palearctic and the Oriental biogeographical realms.…”

The current study enlightens the comprehensive picture, relative population status, and species diversity of lizard fauna in the lower Dir district of Khyber Pakhtunkhwa province, Pakistan. This study was designed to collect the data and record/investigate the population status and the diversity of lizard species from six different tehsils (Towns) in this district. We used the latest keys for identification of the collected and observed specimens. A total of 288 specimens of Lizards were examined, the collected specimens belonged to 6 families, 11 genera, and 14 species. The most abundant and observed species was H. brookii and the most abundant and observed family was Gekkonidae in this area during the current study. In this study, we have identified a new species of the genus Cyratopodion, and we will publish it after a thorough investigation in near future. The present study provides a baseline for future extensive studies on lizard habitat analysis, population dynamics, systematics, and phylogeny for incoming researchers and experts of herpetology.

Astragalus L. sect. Aegacantha Bunge includes 57 described species, mostly confined to Southwest Asia and Central Asia. We studied the pollen morphology of 17 species of this section present in Pakistan. Pollen morphology of sect. Aegacantha species is poorly investigated despite its systematic importance. The main aim of this study is to determine and document the pollen characters that can assist in the taxonomic identification of species in this difficult section. Pollen slides were prepared following acetolysis and examined by both light and scanning electron microscopy. Pollen size varies, with the polar axis ranging from 32.91 to 43.10 µm and the equatorial axis from 22.91 to 28.47 µm. Pollen is sub-prolate (1.15–1.33) to prolate (1.34–2.00) in shape, small to medium in size, radially symmetrical, isopolar, trizonocolporate to tricolporate, and monad. Sculpture variations (i.e. reticulate, microreticulate, perforate, microperforate, regulate, microregulate and granulate) were observed around the apertural, meridional and polar regions. Ordination analysis (principal component analysis (PCA)) revealed that the quantitative characters of pollen morphology are the most reliable characters for delimitation of species within section Aegacantha. Cluster analysis (unweighted pair group method using arithmetic average (UPGMA)) shows a partial relationship between the Aegacantha taxa clustered based on pollen characters and supports the general morphology. Further, this study shows that the pollen traits provide a baseline for phylogenetic optimisation in the investigated Aegacantha section.
