The imago and soldier castes of a new Tauritermes Krishna, 1961 species, Tauritermes bandeirai sp. nov. are described. It is the fourth species of Tauritermes and occurs from the Caatinga and Atlantic Forest of Brazil. Unlike its congeners, the soldier of T. bandeirai has prominent frontal horns.
Imago, new species, soldier, South America
In South America, six kalotermitid genera have soldiers with partial to robust head capsule phragmosis: Calcaritermes, Cryptotermes, Eucryptotermes, Glyptotermes, Proneotermes, and Tauritermes (
Tauritermes, as other kalotermitid genera, is best characterized by venation of the winged imago and soldier head capsule morphology. For Kalotermitidae, most diagnostic characters at the intrageneric level are attributed to head capsule characters.
Herein, we report on a new Tauritermes species, T. bandeirai sp. nov. from samples collected by
Photomicrographs were taken as multi-layer montages using a Leica M205C stereomicroscope controlled by the Leica Application Suite version 3 software. Preserved specimens were taken from 85% ethanol and suspended in a pool of Purell Hand Sanitizer to position the specimens on a transparent Petri dish background.

The soldier of T. bandeirai differs from soldiers of the other three Tauritermes species by having a distinct and robust frontal horn and a roundly protruding dorsal horn (Fig.
The T. bandeirai soldier differs from its congeners in that its frons and horns are more rugose, the basal mandible humps are broader and more angular, and the third antennal article is more club-shaped. Only T. taurocephalus has a similarly shaped postmentum (Figs
The imago head and pronotum of T. bandeirai are mostly unremarkable, except for a relatively large ocellus in comparison with the rather small compound eye. Among kalotermitid genera, the forewing venation is closest to Incisitermes Krishna with one diagnostic exception. In Incisitermes, the median vein is not sclerotized and its terminus does not closely approach the radial sector (

Named for Dr. Adelmar Gomes Bandeira, the graduate and post-graduate advisor of AV who died in 2019. Dr. Bandeira was one of the first termitologists to work on termite ecology in the New World.
The colonies of T. bandeirai were collected inside dry trunks in the beginning stages of decomposition (diameter > 3cm) and in dead terminal branches still attached to the trunks, both in areas of Caatinga and Atlantic Forest. In the Caatinga, colonies of T. bandeirai were relatively easy to extract from dead terminal branches of Commiphora leptophloeos (Mart.) J.B. Gillett (Burseraceae). This tree is also a “hot spot” for collecting other kalotermitids, such as Cryptotermes, Neotermes, and Rugitermes.
Using light traps over a year (December 2017 to November 2018) in a Caatinga area located in the municipality of São José dos Cordeiros, Paraíba-Brazil, the alates of T. bandeirai were collected five times; once in December, thrice in January, and once in February. This period represents a transition between the dry and rainy season in the area. For the Atlantic Forest, alates were recorded in wood in March, June, and December.
There are no records of Tauritermes bandeirai infestations in buildings, either in urban or agricultural environments. Other Tauritermes species infest sound, dry wood (RHS, unpubl.) and are even structural pests (
The Caatinga and the Atlantic Forest are neighboring domains (Fig.
