Collection locality: Iwokrama Research Station , Iwokrama , Guyana ( IWO), GPS: 4°40 ʹ N 58°41 ʹ W; CEIBA Biological station , Madewini Guyana ( CBA), GPS: 6°29 ʹ N 58°13 ʹ W; and Karanambu EcoLodge, North Rupununi, Guyana ( KBO), GPS: 3°46 ʹ N, 59°20 ʹ W . Collection date: 19 – 29 December 2014 . Collectors : D . Evangelista, M. Davis, M. Johnney, M. Carter, O. Ambrose.

Collection/ecological information

All specimens were collected by hand. No ecological information is known.

Morphological identification

We identified this species by comparing pronotal and facial coloration as well as allometry and total size (Rocha E Silva Albuquerque & Gurney 1962).

Genetic information and evolutionary placement

The barcode tree of Evangelista et al. (2014) groups a number of individuals into one clade (Voucher and GenBank accession numbers: DECBA1102 – KF155086 , DECBA 0213–

KF155038 , DECBA0501 – KF155098, DECBA0807 – KF155077 ). The individuals include two juveniles, an adult male and an adult female that we now know are of the same species, due to the genetic data. We include photographs of one of these juveniles (DECBA0501; Figure 4 (a, b)).

Known geographic distribution

Guyana (new record), Brazil (Amapa)

Family ECTOBIIDAE Brunner von Wattenwyl

Subfamily BLATTELLINAE Karny

Genus Dasyblatta Hebard, 1921

History

The genus Dasyblatta was first erected by Hebard in 1921 and included two species: Dasyblatta thaumasia Hebard, 1921 , and Dasyblatta chopardi Hebard, 1921 . Hebard differentiated Dasyblatta from the group ‘ Blattellae ’ by the fact that they were covered in hairs, and had a curled intercalated triangle when wings were at rest. In addition, Hebard noted similarities between individuals of Dasyblatta and Ischnoptera Burmeister, 1838 with regards to the general shape of the body, specifically the head and pronotum. He also believed Dasyblatta to be most closely related to the genera Platylestes Hebard, 1919 and Chromatonotus Hebard, 1920 .

Since 1921 the genus has expanded to include eight species, with the most recently added species being D. charpentierae Bonfils 1975 , D. stylata Bonfils 1975 and D. warei sp. nov., which we describe here.
