RECORDS OF THE STREPSIPTERA OF SRI LANKA IN THE COLLECTION OF THE SMITHSONIAN INSTITUTION, WITH DESCRIPTIONS OF SEVEN NEW SPECIES (Notulae Strepsipterologicae-VI)

Abstract

Based on the material kept at the Smithsonian Institution, Washington, D. C., seven new species of Strepsiptera, Mengenilla orientalis, Stichotrema ceylonense, S. ambiguum, S. krombeini, S. simile, S. minor and Tridactylophagus ceylonensis, are described from Sri Lanka. A species of Paraxenos is also recorded. All of these genera, i. e., Mengenilla, Stichotrema, Paraxenos and Tridactylophagus, are recorded from Sri Lanka for the first time.

A generic classification of Xenidae (Strepsiptera) based on the morphology of the female cephalothorax and male cephalotheca with a preliminary checklist of species

“… Tachytes xenoferus Rohwer, 1911; T. maculicornis Saunders, 1910; T. modestus Smith, 1856 ( Pierce 1911 ; Kinzelbach 1978 ; Kifune and Hirashima 1980 ); T. vischnu Cameron ( Cook 2019 ).…”

“…Algeria; India: Deesa; Thailand: Peninsular Siam; China; Sri Lanka ( Pierce 1911 ; Kinzelbach 1978 ; Kifune and Hirashima 1980 ); Denmark? ( Cook 2019 ).…”

Review of the Genus Malayaxenos Kifune (Strepsiptera: Corioxenidae) with the Description of Four New Species

“…Within the family Corioxenidae there are currently 14 genera (Cook 2019). This study focuses on one of those, Malayaxenos Kifune, 1981.…”

“…The original description of the genus Malayaxenos was based on a single male with a unique combination of characters within the family Corioxenidae (Kifune 1981). Male Malayaxenos have six antennal segments, with flabella on segments three and four.…”

“…The name Malayaxenos was obviously established because of the known distribution of the type species of the genus (Kifune 1981). However, subsequent species discovery suggests that the genus is not necessarily associated with Malaysia as the name suggests.…”
