039D87A1FF99FFD876EAD03AE63838E3.taxon	materials_examined	Material examined: INDIA, Kerala, Chimmony Wildlife Sanctuary, 10.44083 N 76.53527 E, 83 m, Hand picking, 14 - 1 - 2023, 2 w, 1 m, Rakeshwar Kapoor leg. (PUAC). Natural History notes The nests of Diacamma rugosum jerdoni were predominantly located beneath stones. When the stone covering a nest was turned, the nest became exposed, prompting a swift and organized response from the ants. A subset of workers immediately began searching for potential invaders, while the remainder focused on relocating the broods to deeper, more secure areas within the nest. Additionally, a male ant, which had started to move away, was quickly captured by the workers and transported to a safer location deeper in the nest (Fig. 4).	en	Baidwan, Parvinder Singh, Kapoor, Rakeshwar, Bharti, Harmanbir Kaur Randhawa And Himender (2024): Description of Diacamma rugosum jerdoni (Insecta: Hymenoptera) male with two new additions to the myrmecofaunal diversity of Kerala.

039D87A1FF9BFFD876EAD1F1E4383C84.taxon	description	Worker diagnosis: Crematogaster dalyi belongs to the ranavalonae group and can be distinguished from other groups by specific morphological characteristics, including a steeply raised pronotum, a smooth and shiny body surface, and short, appressed body setae. This group encompasses five species in India and C. dalyi is distinguishable by the following combination of features: abundant setae on the scape, in dorsal view markedly bilobed postpetiole that is more than twice as broad as it is long and short propodeal spines, the length of which is equal to or shorter than the diameter of propodeal spiracles. While Crematogaster dalyi looks quite similar to C. sikkimensis, a key distinguishing factor is the length of the propodeal spines — those of C. dalyi are considerably shorter.	en	Baidwan, Parvinder Singh, Kapoor, Rakeshwar, Bharti, Harmanbir Kaur Randhawa And Himender (2024): Description of Diacamma rugosum jerdoni (Insecta: Hymenoptera) male with two new additions to the myrmecofaunal diversity of Kerala.

039D87A1FF9AFFD676EAD619E6663AD6.taxon	description	Worker diagnosis: The petiole of this species is nodiform and the head is smooth. The first gastral segment is predominantly smooth, exhibiting only widely spaced sparse piligerous punctulae. In dorsal view, the petiolar node is either broader than long or approximately as broad as it is long. The dorsum of the petiole is broadly rounded in lateral view. The cephalic dorsum is smooth and shining, with, at most, sparse piligerous punctulae. The pronotum is scrobiculate. This species bears a close resemblance to Leptogenys lucidula. However, a distinguishing feature is observed in the pronotum; in L. lucidula, the pronotum is smooth.	en	Baidwan, Parvinder Singh, Kapoor, Rakeshwar, Bharti, Harmanbir Kaur Randhawa And Himender (2024): Description of Diacamma rugosum jerdoni (Insecta: Hymenoptera) male with two new additions to the myrmecofaunal diversity of Kerala.

(PUAC). The habitats of the documented species were primarily within mixed tropical rainforest ecosystems. The microhabitats for each species were as follows: Diacamma rugosum jerdoni was predominantly found beneath stones, Crematogaster dalyi exhibited arboreal nesting behavior and constructed carton nests and Leptogenys emiliae was located in decomposing wood. A view of each species habitat is provided in Fig. 7. The newly determined species contribute to Kerala's diverse ant fauna, now comprising eleven Crematogaster and seventeen Leptogenys species. A species list of these two genera is given in table 2. As a part of the Western Ghats biodiversity hotspot, Kerala's rich biodiversity holds promise for further discoveries through ongoing surveys, showcasing the need for continued exploration and conservation efforts.	en	Baidwan, Parvinder Singh, Kapoor, Rakeshwar, Bharti, Harmanbir Kaur Randhawa And Himender (2024): Description of Diacamma rugosum jerdoni (Insecta: Hymenoptera) male with two new additions to the myrmecofaunal diversity of Kerala.
