Disjunctitermes insularis, a new soldierless termite genus and species (Isoptera, Termitidae, Apicotermitinae) from Guadeloupe and Peru.

ABSTRACT: Disjunctitermes insularisgen. n. & sp. n. is described from workers collected on Guadeloupe and in Peru and is the first soldierless termite found on a deep-water island. As with many soldierless and soil-feeding termite species, the enteric valve morphology is an essential diagnostic character of D. insularis. The D. insularis sequence cluster, derived from a barcode analysis with twelve other described genera of New World Apicotermitinae, is well resolved. Results of a stochastic dynamic spread model suggest that the occurrence of D. insularis on Guadeloupe may be the result of a pre-Colombian overwater dispersal event from mainland South America.

A new genus and species of mandibulate nasute termite (Isoptera, Termitidae, Syntermitinae) from Brazil.

Project description:Acangaobitermes krishnaigen. et sp. n., is described here, based on soldiers and workers collected in Brazil. Some characteristics suggest a close kinship with Noirotitermes Cancello & Myles, and both genera share the following traits absent in all other Syntermitinae: the microsculpturing on the soldier head capsule surface with internal granulations; the piercing mandibles with a single very reduced marginal tooth and the worker very similar in both genera. The most conspicuous differences between Acangaobitermes and Noirotitermes are the shape of the soldier head, the frontal tube and pronotum. The shape of the soldier head in Noirotitermes is unusual, with a very broad and short frontal tube, four conspicuous protuberances like sharp corners at the rear, while in the new genus the posterior contour of the head is devoid of these protuberances. The frontal tube of Acangaobitermes is elongate and conical, while in Noirotitermes it is short and very broad. The pronotum of Acangaobitermes is saddle-shaped as is usual in other Syntermitinae, while it is aberrant in Noirotitermes.

Uncitermes almeriae, a new termite species from Amazonia (Isoptera, Termitidae, Syntermitinae).

Project description:The Neotropical termite genus Uncitermes Rocha & Cancello, 2012 was known from a single species, Uncitermes teevani (Emerson, 1925). In this paper a new species, Uncitermes almeriae sp. n., is described and illustrated from worker and soldier castes, along with observations on the Uncitermes nest. A distribution map with the occurrences of both species is presented. The new species is distinguished from its congener by the presence of short bristles covering the head capsule and frontal tube.

A new genus and species of termites (Isoptera, Termitidae, Nasutitermitinae) from the rainforest of northern Peru.

Project description:A new genus and species of nasutitermitine termites are described and illustrated, based on soldier and worker characters. Sinqasapatermesgen. n., can be distinguished from all other nasutitermitine genera by its singular worker gut coiling and enteric valve characters: distal margin of the enteric valve not everted into the paunch but bending towards the ileum, that is, directed against the flow of food; enteric valve armature with one ring of six equal subtriangularly-shaped ridges, each ridge with short spines on the entire surface; enteric valve armature situatedonexternal face of cone, facing the internal ileum wall; enteric valve seating tri-lobed and separated from remaining portionof the paunch; paunch subdivided. Sinqasapatermes sachaesp. n., was collected on a tree in a very narrow flattened tunnel that was well concealed beneath lichens in a northern Peru rainforest (Arcadia, Loreto Province).

A new termite (Isoptera, Termitidae, Syntermitinae, Macuxitermes) from Colombia.

Project description:A new species of termite, Macuxitermes colombicus Postle & Scheffrahn is described from soldiers and workers collected from Departamento Magdalena, Colombia. The soldier of Macuxitermes colombicus differs from its lone congener in having no protuberances on the head capsule.

Parvitermes (Isoptera, Termitidae, Nasutitermitinae) in Central America: Two new termite species and reassignment of Nasutitermes mexicanus.

Project description:The termite genus Parvitermes is now recognized on the Central American mainland to include Parvitermes mexicanus, new combination (previously in Nasutitermes) and two new species, Parvitermes mesoamericanus sp. n. and Parvitermes yucatanus sp. n., herein described from soldiers and workers. These three species, nine West Indian Parvitermes, and Antillitermes subtilis all share characteristic enteric valve spines that orientate against intestinal flow. All species are subterranean nesters and cellulose feeders. Evidence is mounting that generic-level endemicity may be completely absent among the West Indian nasutitermitine fauna and that its origins stem from Central America.

Rhynchotermes armatus, a new mandibulate nasute termite (Isoptera, Termitidae, Syntermitinae) from Colombia.

Project description:Rhynchotermes armatus sp. nov. is described from soldiers and workers collected in the Magdalena River Valley of Colombia. Both castes of this new termite are superficially similar to R. perarmatus (Snyder) but the former are smaller, head capsules yellowish instead of reddish, and among additional characters, the soldier has narrower mandibles and marginal teeth.

Hospitalitermes krishnai, a new nasute termite (Nasutitermitinae, Termitidae, Isoptera), from southern Sumatra, Indonesia.

Project description:A new species of nasute termite, Hospitalitermes krishnaisp. n., is described from soldiers and workers discovered in Lampung Province, Sumatra. This species can be distinguished from other related Hospitalitermes species from Southeast Asia by the anterior part of head capsule that is much smaller than the posterior part, head capsule that is moderately constricted behind the antennal sockets, and relatively deep depression between the head and nasus and, finally, the short and robust nasus measuring less than half as long as head capsule. Moreover, in profile the nasus is slightly up-curved but slightly decurved at the apical tip. We name this new species after Professor Kumar Krishna in recognition of his life-long contributions to termite taxonomy, systematics and biology.

Echinotermes biriba, a new genus and species of soldierless termite from the Colombian and Peruvian Amazon (Termitidae, Apicotermitinae).

Project description:A new Apicotermitinae genus and species Echinotermes biriba is described from workers collected on the Andean-Amazon Piedmont in Colombia and Peru. The enteric valve armature of Echinotermes biriba Castro & Scheffrahn, gen. et sp. n. is a remarkably diagnostic character. A Bayesian phylogenetic analysis using the COI gene and including all other Neotropical Apicotermitinae genera, supports the new genus as a distinct terminal.
