Type species: Abaddon despoliator Derkarabetian , sp. nov., by monotypy.
Diagnosis
This genus is very distinctive and can be easily distinguished from Lomanella , and all triaenonychids known from Western Australia, based on its highly tuberculate – spiny body ( Fig. 6 View Fig , S 4 View Fig ). Compared to Lomanella , it has a penis with large lateral wing-like laminae, an elongate and tubular stylus rising directly from the sensillar region (sensillenträger of Martens 1986), without dorsal or ventral plates.
Description
Eye mound recessed from the anterior margin of the carapace, tuberculate and heavily pigmented ( Fig. 6 A, B View Fig ). Anterior margin of carapace with large anteriorly directed spines, the medial spine being the largest ( Fig. 6 A, B View Fig ). Dorsal scutum outline in dorsal view outline Eta H of Kury and Medrano (2016), with a slight widening at the midline. Body densely covered in brown pigmented tubercles except along lateral margins, with lateral projections above coxae II associated with ozopores ( Fig. 6 A, B View Fig ). Each scutal segment with a row of large spines, generally increasing in number posteriorly. Coxae II with an elongate dorsal tubercle associated with ozopore; coxae IV with a small pigmented area dorsally ( Fig. 6 A, B View Fig ). Ventral surface of body tuberculate; leg I coxae with a series of elongate tubercles along prolateral margin; sternum long and narrow ( Fig. S4 B View Fig ). Genital operculum subtriangular and tuberculate. Pedipalps without heavy spination, one spine-bearing tubercle ventrally on the femur, tarsus with an elongate claw and elongate spines terminally ( Fig. 6 E View Fig ). Leg I femur with a series of elongate dorsal and ventral tubercles bearing setae ( Fig. 6 C, D View Fig ). Leg coxae tuberculate, legs with rows of longitudinal tubercles. Tarsal formula 2,2,3,3. Penis without dorsal or lateral plates; with large lateral wing-like laminae; stylus elongate, thin, and tubular, arising directly from the sensillar region ( Fig. 7 A View Fig ).
Etymology
The genus name is in reference to the fictional character ‘ Abaddon the Despoiler’ from the Warhammer 40 000 tabletop miniature game and science fiction universe developed by Games Workshop, which is a favourite hobby of the first author. The character is typically portrayed adorned with spikes and various sharp things. The name should be treated as masculine.
