Moth Diversity at Sebangau Peat Swamp and Busang River Secondary Rain Forest, Central Kalimantan

A study on the diversity of moths was conducted from July to Augustus 2004 at the peat swamp forest Setya Alam research station, Sebangau, Central Kalimantan. The result showed that diversity of moths at this area was lower (100 species of 12 families; H’ = 6.643, E = 0.794) than that in secondary rain forest Busang River (278 species of 19 families; H’ = 8.139, E = 0.831). The result also showed that the similarity index (Cj) of the two areas was very low (0.05). Geometridae, Noctuidae, and Pyralidae were dominant in both areas. There might be more species that have not been found during eight night sampling as indicated by the species numbers in both areas has not reach a plateau.

Evolution of a Wingless Gene and its Utility for Inferring the Relationships within Glyphodes Moths

The evolution of a nuclear Wingless gene was investigated and its utility for inferring the phylogenetic relationship within Glyphodes moths was assessed by comparing with other three genes namely, COI, COII, and EF-1?. The results show that the bias of base compositions in Wingless (C: 0.19) is the lowest among those in COI, COII, and EF-1?. The averages of nucleotide sequence divergences for comparison between groups based on the Wingless were the highest. While substitutions in Wingless and EF-1? genes were not saturated at the divergence of the species groups, COI and COII genes attained saturation at those levels. The phylogenetic analysis based on Wingless solely show that this gene was very useful to resolve the relationships between groups but gave a poor resolution at the specific level, i.e. the relationships within group 1 was not resolved. Combination of all data supports the phylogenetic hypothesis based on morphological data. Glyphodes falls into three species groups: group 2 branched off first then followed by groups 1 and 3. Key words: COI, COII, EF-1?, genes, Glyphodes, mitochondria, moth, phylogeny, relationships, Wingless

Molecular Phylogeny of Agrioglypta Meyrick and Talanga Moore (Lepidoptera: Crambidae; Spilomelinae) Inferred from Nuclear EF-1α Gene

The phylogeny of the two closely- related genera, Agrioglypta Meyrick and Talanga Moore, was inferred from nucleotide sequence variation across a 973-bp region in the nuclear elongation factor-1 (EF-1) gene. Seven species representing the two genera and two outgroup species (Feltia jaculifera Guene and Metallarcha aureodiscalis Meyrick) were analyzed. The results showed the averages of the p-distances in the comparisons between species within genus and between species belonging to other different genera were 3.5% and 4.9%, respectively. EF-1 gene had almost reached saturation at the level of the divergence of these two genera. The phylogenetic analysis using MP and NJ methods showed that each genus was found to be a monophyletic group and the species relationships within each genus were almost consistent as well. A. eurytusalis is the basal species in the genus Agrioglypta. In the genus Talanga, T. sabacusalis lied in the basal node and T. tolumnialis was found to be sister group of T. sexpunctalis.

Discovery of Cryptophasa Lewin, 1805 (Lepidoptera: Xyloryctidae) from Indonesia with the descriptions of three new species

Three new species of Cryptophasa Lewin, 1805 are described from eastern Indonesia: C. watungi Sutrisno & Suwito, 2015 sp. nov., C. kwerbaensis Sutrisno & Suwito, 2015 sp. nov., and C. choliki Sutrisno & Suwito, 2015 sp. nov. Each species is described based on adult external and genital characters. The potential apomorphic character in male genitalia of Cryptophasa, the shape of the uncus, is discussed.
