Introduction

Ants are eusocial insects that belong to family Formicidae of the order Hymenoptera. They are said to be present on earth about 120 million years ago (Ward, 2007). They are one of the most diverse and pervasive group of the social insect within order Hymenoptera (Bolton, 2011). Ants are further classified into 26 subfamilies with about 16,318 described species in 482 genera (Bolton, 2021). There are 103 ant species in 35 genera and 7 subfamilies reported from Pakistan (Rasheed et al., 2019).

Pseudoneoponera Donisthorpe, 1943 is a moderately large genus with 18 described species widely distributed from India to Australia. Genus Pseudoneoponera is well known for their unusual foamy secretions exuded from the stings of workers for its small colonies and usual social systems including the frequent occurrence gamergates (Schmidt and Shattuck, 2014).

In current study one species of this genus representing the first report from Azad Kashmir, Pakistan with descriptions of morphological characters.

Materials and Methods

Ant’s specimens were collected from Kahuta, Azad Kashmir, Pakistan during May, 2020. Collected specimens were observed under the stereo microscope Nikon SMZ 745T and pictures were captured with Nikon DS-Fi2 digital camera attached to the microscope. Terminologies of Hollodobler and Wilson (1990) were followed for morphological descriptions (Figure 1).

Results and Discussion

Genus Pseudoneoponera Donisthorpe, 1943

The genus Pseudoneoponera was synonymized with Bothroponera by Wilson (1958), with Pachycondyla by Brown (1994) and ultimately placed it in the tribe Ponerini by Bolton (2003). However, based on the recent molecular phylogenetic analysis (Schmidt, 2013); Schmidt and Shattuck (2014) the genus Pseudoneoponera is recognized as separate genus and placed under the Odontomachus genus group of the tribe Ponerini.

Description

Body Length: 14.11mm.

Body colour: Dull black in color; legs, antenna and metasomal end dark rufous.

Vestiture: Body clothed with long outstanding and short sub-decumbent dense yellow hairs.

Head: Head with dense hairs, coarsely sculptured, oblonged with convex sides; flagellum 11 segments; preoccipital carina laterally and dorsally conspicuous; frontal lobes straight, separated by longitudinal sulcus from each other; Antenna 12 segmented thick, short, without scrobe; clypeus usually with a pair of median carina, medially with anterior face sharp; clypeus with antero-median margin convex; mandibles usually sub-triangular, basal portion dorsolaterally with fovea, strongly toothed; eyes small sized and anterior.

Mesosoma: Mesosoma with dense hairs, coarsely sculptured, posteriorly truncate and not furrowed; metanotal groove absent; mesonotum with distinct suture, metapleuron separated from mesopleuron; propodeum exposed; propodeal spiracle with orifice slit like; propodeal lobe nearly absent; pronotum separated from mesonotum by promesonotal suture; front tibia with a small apicoventral spur behind large pectinate spur; apicoventral part of hind and mid tibia with small spur in front of large spur; petiole with anterior peduncle absent; petiolar node dorsally semi-circular, thick and high laterally; row of denticles present on posterodorsal margin of petiolar node.

Metasoma: Metasoma usually long with joints divisions marked strongly; hairs dense and short; metasomal segments 3 and 4 with distinct girdling construction; petiole sub rectangular; tergite 3 longitudinally striate strongly; 3rd sternite with distinct anteroventral flange; last segments of metasoma dark rufous; sting well developed, sharp and upcurved.

Distribution: The species Pseudoneoponera rufipes is widely distributed in Oriental region: Vietnam, Thailand, Sri Lanka, Pakistan, Nepal, Laos, India and Palaearctic region: China (AntWeb, 2021). It is previously reported from Rawalpindi, Pakistan by Rasheed et al. (2019).

Material Examined: Pakistan; Azad Kashmir, Kahuta, 2♀. 33.5896° N, 73.3886° E. 14.vi.2019. Ullah, N.

Comments: It can be identified by: Metasomal end dark rufous; metasoma with pedicle posteriorly excavated, truncate and thick; mesosoma posteriorly truncate and not furrowed; jaw usually finely toothed and sub-triangular; antenna 12 segmented. In the present study the species is reported for the first time from Kahuta, Azad Kashmir Pakistan.

Conclusions and Recommendations

The area contains rich ant fauna and very little work is done till date. As this species is the new record for Kahuta Azad Kashmir, it is recommended that an extensive collection should be made in order to completely explore the ant fauna of Kahuta, Azad Kashmir.
