Metaphire peguana species-group

Diagnosis. Members of the species-group can be recognized by the following characters: two pairs of accessory glands coelomic, strongly covered by muscular-walled bursae, septum 10/11 only present ventrally. In addition, the group members also have spermathecal pores usually three pairs in 6/7/8/9, sometimes four pairs in 5/6/7/8/9 or numerous in 6/7/8/9 or 7/8/9; two pairs of genital markings in 17/18 and 18/19 or on segment xvii and xix (if not within a copulatory pouch).

Remarks. A total of seven species and subspecies were assigned to this species-group, namely M. bahli , M. doiphamon , M. dorsomultitheca , M. kiengiangensis , M. nhuongi , M. peguana peguana , and M. peguana laisonensis . Out of 7 species/subspecies, M. bahli and M. peguana peguana have been distributed widely, from South America ( French Guiana), Australia, South Asia ( India, Bangladesh, and Sri Lanka), East Asia ( Japan), and found commonly in Southeast Asia ( Myanmar, Laos, Cambodia, Thailand, Singapore, Vietnam, Malaysia, Philippines, and Indonesia) ( Fig. 3 View FIGURE 3 ). Other five members have been recorded only in Southern Vietnam, so far ( Fig. 3 View FIGURE 3 ) ( Michaelsen 1922; Gates 1925, 1945, 1972; Easton 1982; Thai & Do 1989; Ishizuka 1999; Shen & Yeo 2005; Blakemore et al. 2006; Csuzdi & Pavlíček 2010; Sarkar & Bandyopadhyay 2012; Prasankok et al. 2013; Ng et al. 2017; Narayanan et al. 2019; Nguyen et al. 2016, 2020, 2021a, 2021c; Lam et al. 2021).
