Description

Sculpturing of antennal scrobe developed as transverse carinulation in front, turning into reticulum in posterior section; sculpturation on dorsal surface of mesosoma consisting of large, widely spaced foveae; interspaces between foveae on dorsum and lateral surface of mesosoma, as well as vertex wide and shining, but with fine rugoreticulum; similar rugoreticulum present also on, otherwise shining, dorsal and lateral surfaces of petiole and postpetiole; propodeal spines relatively long and thin; dorsal surface of petiole in lateral profile uniformly convex, without distinct dorsal and posterior faces and forming blunt angle with anterior face; anterior face of petiole in lateral view shallowly concave; in dorsal view, anterior and posterior regions of postpetiole are of the same width; body pilosity consisting of long, apically curved hairs present on dorsal surface of head, and short, appressed pubescence present on head, dorsal surface of mesosoma, postpetiole, gaster, and appendages.

Measurements of holotype worker: CI 1.02; HL 0.43; HTL 0.25; HW 0.44; ML 0.49; PW 0.28; SI 0.61; SL 0.27

3. Mayriella warchalowskii  HNS  , holotype worker: front of head

Diagnosis

The new species can be easily separated from two other Oriental Mayriella  HNS  by 1) the smooth, wide interspaces of foveae present on lateral and dorsal surfaces of promesonotum, and 2) different shape of petiole. In both M. transfuga  HNS  and M. granulata  pro-mesonotal region is very heavily sculptured with foveae almost touching each other, and dorsal surface of petiole is meeting its anterior face at a sharp angle. M. warchalowskii  HNS  can be considered somewhat similar to M. sharpi Shattuck & Barnett  , 2007, but the new species lacks ventrally pointed eye characteristic of sharpi  . Combination of large foveae with wide, shining interspaces on lateral surface of pro-mesonotal region, relatively low and long petiole, and lack of long hairs on mesosomal dorsum allows quick separation from other species of the genus.

Comments

Unfortunately, this species is described from only one specimen so nothing can be said about infraspecific variability of characters, which sometimes can be considerable,

as in M. abstinens  HNS  Forel, 1902 (Shattuck & Barnett 2007).
