Genus 4. Bischoffitilla Lelej, 2002

Diagnosis. FEMALE. The only eastern Oriental member of Myrmillinae . This genus has the mesopleural suture complete and connecting with mesonotal tubercle; inner margin of mandible with distinct tooth in basal third; T1 with apicomedial setal spot that sometimes extends to the base of T2; and T2 with a thick apical setal or cuticular band. For additional diagnostic features, see Lelej (2002). MALE. See Lelej (2002).

Diversity and Distribution. This genus includes 73 predominantly Oriental species ( Lelej 2002, 2005; Terayama et al. 2011).

Remarks. The majority of Oriental Myrmillinae , including all the known eastern Oriental Myrmillinae , belong to Bischoffitilla . Only B. lamellata (Mickel, 1933) was previously known from Thailand. The expeditions in 2017 and 2018 recovered B. lamellata and three other species of females in southern Thailand. Additional species from this diverse genus are likely to be recovered throughout Thailand. Older keys (e.g. Mickel 1935, Chen 1957) treat these species under the name Squamulotilla Bischoff, 1920 .
