Summary: A new subspecies of the genus Cricula Walker, 1855 (Lepidoptera: Saturniidae) is described and figured from the arid Lesser Sunda Islands, Indonesia: Cricula trifenestrata tenggarensis subsp. nov. The new subspecies tenggarensis is given a toponimic name referring to the islands of Nusa Tenggara (the Lesser Sunda Islands). Thus far, the new subspecies is only known from the island of Sumba, Eastern Lesser Sunda Islands, Nusa Tenggara Timur Province (NTT), but may occur on adjacent islands as well. The taxonomic status of the populations of the trifenestrata species-group (sensu Nässig 1995) from the islands of Flores, Sumbawa and Lombok remains unknown, because only a very few specimens are known in collections and still nothing is known on the preimaginal instars. Presently we do not believe that the populations of C. trifenestrata from the islands of Sumba and Flores are conspecific [remarks: further studies by the authors revealed that the populations of the trifenestrata species-group from the islands of Flores, Sumba and Sumbawa being conspecific]. Further descriptions of new taxa from the Lesser Sunda Islands are postponed until more specimens are available and their preimaginal instars are known. C. trifenestrata tenggarensis subsp. nov. is mainly compared with the closely related C. trifenestrata javana Watson, 1913 from the islands of Java and Sumatra. The populations of C. trifenestrata from the Cameron Highlands, Peninsular Malaysia are considered being distinct on subspecific level [remarks: presently two taxa of the trifenestrata species-group are recognized for Peninsular Malaysia of which each one is placed in subspecific level to trifenestrata and the other considered distinct on species level]. The taxonomic status of other populations from Peninsular Malaysia, northern Thailand, and the northeastern Moluccas needs further studies. Presently eleven taxa of the trifenestrata species-group are considered valid subspecies of the widely distributed C. trifenestrata (Helfer, 1837), including the nominotypical subspecies and the new subspecies tenggarensis. Due to the large overall similarity and individual variability, the external morphology and the male genitalia generally do not offer good characters for identification on subspecific level. Therefore it is often hardly possible to identify a specimen of the trifenestrata species-group if its collecting place is unknown. A few taxa within the trifenestrata species-group share the same significant characteristic in the male genitalia structures. They show a variable tendency to reduce the basal left cornutus in the vesica of the aedoeagus. Those taxa are C. trifenestrata serama Nässig, 1989 from the island of Seram, Moluccas, C. bornea Watson, 1913 from East Malaysia, C. trifenestrata treadawayi Nässig, 1989 from the island of Negros, Philippines, C. trifenestrata banggaiensis Naumann & Paukstadt, 1997 from the Banggai Archipelago, Indonesia, and finally C. trifenestrata tenggarensis subsp. nov. from the island of Sumba, Lesser Sunda Islands. Additional to the reduction of either the left basal cornutus or combined the left basal and the left apical cornuti the ventro-distal extension of the juxta (sella) is shorter in C. trifenestrata tenggarensis subsp. nov. In both sexes the habitus and the morphology of C. trifenestrata tenggarensis subsp. nov. are similar to other related taxa of the trifenestrata species-group. The adults show a clear sexual dimorphism and mimesis of dead leaves. In C. trifenestrata tenggarensis subsp. nov. the fore wing apices are slightly more prominent in both sexes and mostly a greater number of fore wing fenestrae is present in the male. In the female the arrangement of the fore wing fenestrae is different from those in C. trifenestrata javana. Although C. trifenestrata from the island of Java is a considerable variable taxon, no color variations were found in the new subspecies, except occasional a dark brown morph in both sexes. The male holotype of C. trifenestrata tenggarensis subsp. nov. and some paratype specimens are donated to the Museum Zoologicum Bogoriense (MZB), Cibinong (Bogor), Indonesia.
