Gapon, Dmitry A., 2018, Morphology of male and female terminalia and taxonomic revision of the burrower bugs genus Canthophorus (Heteroptera: Cydnidae), Annales de la Société entomologique de France (N. S.) 54 (3), pp. 183-228 : 29

Canthophorus melanopterus mariae n. ssp. ( Figures 7 F , 9 D , 14 I )

Type material

Holotype: Tajikistan: Varzob Distr., Gissar Range, Varzob Riv. valley, Kondara Gorge [38°48 ʹ 55.5 ʺ N 68° 47 ʹ 26.1 ʺ E], 1110 m, 12.VII.1955 (Kulinich), ♀ ( ZISP) .

Paratypes: Tajikistan: Varzob Distr., Gissar Range, Varzob Riv. valley, Kondara Gorge , 1110 m amsl, 22. VI., 5.VII.1938 (Gussakovskij), 1J, 2♀ ( ZISP), 1♀ ( MNHN) ; Vahdat Distr., Gissar Range, Romit Nat. Park , vicinity of “Romt” [Romit], 6–7.VI.1982 (G. Medvedev), 3J, 6♀ ( ZISP), 1♀ ( MNHN) .

Diagnosis

Yellowish rib on lateral margins of pronotum and hemelytra thin, narrower than base of antennal segment II; proximal tubular part of spermathecal capsule approximately 3–4 times as long as transverse diameter of distal spherical part of capsule ( Figure 9 D ); posterior pouches of gynatrial sac posteriorly strongly shortened; sclerotisation inside posterior pouches shaped as narrow, arcuately curved band with irregular margins, one end directed lateroposteriad and opposite end directed medioanteriad ( Figure 14 I ), or sclerotisation almost lost except for very thin, weakly sclerotised plate along anterior inner wall of pouch and visible as very thin band in dorsal view (as in form 6 of C. m. melanopterus ). The new subspecies is also distinguished from C. m. contrarius and Mediterranean specimens of C. m. melanopterus by long lateral branch of vesica, and from C. m. contrarius by brownish, opaque membrane.

Variability

In two males from Kondara Gorge, distal denticle of sclerite basal plate at dorsolateral lobes of conjunctiva wider than in other examined specimens of the species ( Figure 7 F ). Among specimens from vicinity of Romit, one female with posterior pouches having in addition to arcuate sclerites, also a pair of large, formless longitudinal sclerites lying along anterodorsal margin of pouch and connected with posterior ends of arcuate sclerites; in another female, arcuate sclerites very narrow, connected by posterior end with very narrow sclerotised band lying along anterodorsal margin of pouch; in remaining females, arcuate sclerites rather wide and sclerotised band along anterodorsal margin of pouch poorly noticeable; in one female, right arcuate sclerite shorter and narrower than left sclerite; in two specimens, right arcuate sclerite large but weakly sclerotised, left arcuate sclerite absent. In two females from Kondara Gorge, arcuate sclerites absent and sclerotised bands along anterodorsal margins of pouches poorly noticeable.

Measurements

Body 5.65–7.90 in length, 3.35–4.8 in width; pronotum 3.05–3.95 in width; head 1.37–1.64 in width; ocular index 3.76–5.64; length of antennal segments I–V: 0.31–0.39: 0.49–0.60: 0.56–0.70: 0.80–0.98: 0.91–1.06.

Etymology

The subspecies is named after Maria Berlina, the senior custodian of the Rhynchota collection in ZISP, who helped me in dissection of the female terminalia and was the first to see the diagnostic characters of this new taxon.
