Connatocryptus utiku sp. nov.

( Fig. 19 )

Type material. Hඈඅඈඍඒඉൾ: female ( NZAC) [removed from original point card and repointed], labeled: “Utiku 30.6.17 [ T. Broun’s hand] // T.Broun Collection // A. E. Brookes Collection // Crypto. No. 11 [C. Watt’s hand] // Cryptophagini sp. nov. [ R. Crowson’s hand] det. R. A. Crowson”.

Diagnosis. This is the only known member of the genus; therefore, it may be recognized by the characters given in the generic diagnosis above.

Description. Length 2.67 mm. Color of body ( Fig. 19 ) reddish-brown, elytra, legs and mouthparts lighter. Dorsal setae uniformly silver, vestiture converging to central point on pronotum, undulating on elytra with setae near midlength directed medially and subapical setae directed laterally. Ventral surfaces with recumbent setae with similar length to that of dorsum; densely punctate on most surfaces; prosternum with large, coarse punctures that weaken posterolaterally; prosternal process with decumbent setae; punctation of metaventrite less coarse than that of prosternum, uniform on disc, but weakening posteriorly; abdominal ventrites with punctures denser and smaller than those of metaventrite, especially ventrites 3–5 which are micropunctate, ventrite 5 bearing a patch of posteriorlydirected setae.

Head punctate with smooth interspaces. Antennomere 2 globular, about as long as is wide, antennomere 3 subconical with base slightly narrower than apex, about as long and as wide and slightly shorter than 2, antennomere 4 smaller in width and length than 3 and slightly shorter than 5; antennomere 11 not much longer than 10, distinctly shorter than 9 and 10 combined. Pronotal length/width ratio ~0.67, widest at middle, wider across posterior angles than across anterior angles; lateral edges evenly curved, anterior angles not projecting, posterior angles right, not projecting, posterior margin sinuate, with weak, truncate scutellar lobe; pronotum lacking deep medial basal impression;paralateral plicae absent; pronotal punctation similar to that of frons but more regular over much of the disc, punctures separated by 1–2.5 puncture diameters, with smooth interspaces, punctures larger and fusing at the posterior margin of the base and becoming rugose. Elytra about 1.56× longer than combined width, about 1.17× wider than pronotum at greatest width, about 2.03× longer than pronotum at greatest length; punctation sparse and weakly impressed, punctures separated by about 5 puncture diameters, not markedly denser near basal margin than on disc; sutural stria present to midlength; disc lacking impressions.

Remarks. The bicolored appearance of the elytra is a result of the folded hind wings beneath the elytra.

Etymology. Named for the type locality, Utiku (RI), lying at approximately 39°43.906′S, 175°50.627′E in the North Island of New Zealand.
