Resembles its most similar congeners – A. terraesanctae and A. cypria sp. nov. – by the anterior gonopods possessing well-developed colpocoxites, and an elaborate median lamella, which is more or less densely covered with long, setiform filaments; and by the posterior gonopods consisting of large, relatively stout angiocoxites, bearing several setae and rather prominent telopodital rudiments, and of fine, membranous colpocoxites. Differs from them mostly by the lateral arms of the anterior gonopods being blunt and barely bent caudad, rather than tapering and strongly bent caudad. Further morphological differences between the 3 species are summarized in Table 1.


This species is named in memory of Karl Strasser (1903–1981), a prominent myriapodologist who, among other things, described several species of Anamastigona .

Type material


CYPRUS: ♁ (in 3 parts: head + first 6 segments, segment 7 and rest of body; half-broken behind segment 18), FC0003, Paphos, Pano Panagia village , next to a winery, patches with Eucalyptus , 800 m, hand collection, 8 Nov. 2011, S. Simaiakis leg. ( NHMC).


MEASUREMENTS. Body segments 28 +1+T, 8.2 mm long, 0.7 mm high at mid-body, 0.85 mm maximal width.

COLOURATION. Marbled brownish (somewhat more contrasting compared to A. cypria sp. nov.), more intense on posterior half of body; with blackish transverse stripes dorsally on prozonae; ventral side and legs beige to light brown; large, light, cloud-like spots present dorso-laterally just above shoulders.

EXTERNAL STRUCTURES. Tegument smooth, only hind margins of pleuroterga finely striolate dorsally. Head with 19–20 blackish ocelli arranged in 8 oblique rows: 1 +1+2 +3(2) +3 +4+ 3(4) +2(3), counting from hind lower corner of ocellarium. Head rather sparsely setose: vertex and upper part of frons bare, lower part of frons and labrum moderately densely covered with two types of setae – some very short ones, the others ca 2 times as long; several very short setae on occiput. Frons flat or very gently convex. Antennae almost 2 times as long as head; antennomeres 2, 4 and 6 subequal, antennomere 3 ca 2 times longer, slightly shorter than antennomere 5. Labrum tridentate. Gnathochilarium with rather large, triangular, somewhat broader than long promentum; stipites with several long lateral setae. Collum with median longitudinal groove. In width, collum <segment 2 <head = 3 <4 <5 = 8–18 (19) <6 <7; after segment 19 increasingly narrowed towards telson. Axial suture well-developed, thin. Stricture between pro- and metazonae quite broad and rather shallow. Paraterga small, rounded, dorsolateral swellings, most prominent on segments 8–19, then gradually diminishing towards telson, completely disappearing on segments 28 and 29. Metatergal setation typical (macrochaetae mostly broken off), macrochaetae 0.2–0.25 mm long. CIX (15) = 0.6, MIX (15) = 1.6, MA (15) = 135º. Pleurotergum 7 almost unmodified, its ventral margin forming very low ridge. Epiproct truncated caudally, caudal margin with several small, rounded, scale-like protuberances. Each paraproct with single long marginal seta. Hypoproct semi-elliptic, with two long marginal setae.

LEGS. Pairs 1 and 2 shortest, with very thin prefemur and femur, mesally with tarsal brushes; coxa 2 with gland opening; pairs 3 and 4 ( Fig. 5A View Fig ) very thick, with stout, shortly bifurcated bump dorso-parabasally on prefemur; 5–7 increasingly longer, tarsus of 7 ( Fig. 5B View Fig ) very long, ca 1.6 times as long as postfemur + tibia; coxa 10 ( Fig. 5C View Fig ) ventrally expanding into cylindrical process, expanding apically into somewhat curved, foam-like protrusion; coxa 11 ( Fig. 5D View Fig ) with two processes: a proximal, ventral one, similar to that on coxa 10, the other a distal, ventro-anterior, short and blunt, process; leg 24 ca 1.3 times as long as mid-body height, its tarsus ca 2 times as long as postfemur + tibia.

GONOPODS ( Fig. 6 View Fig A–D). Anterior gonopods ( Fig. 6 View Fig A–B) similar to those of A. cypria sp. nov., the main difference being the lateral arms (la), which are uniramous, apically blunt/narrowly rounded, barely bent caudad. Posterior gonopods ( Fig. 6 View Fig C–D) reduced; angiocoxites (a) stout, flattened apically, microsquamate, caudo-laterally with several setae; telopodital rudiments (te) short, rounded, composed of 2 articles, pigmented, positioned caudo-latero-parabasally on a; colpoxites (k) placed almost one behind the other rather than side by side, slender, somewhat lower than a.


The position of the posterior gonopod colpocoxites in this species is unusual – they are almost completely oriented one behind the other, rather than next to each other, i.e., more perpendicular than parallel to the sternal axis. However, in the presence of only one examined male, this peculiarity may represent nothing more than individual variation.
