Crypticerya morrilli (Cockerell)

Palaeococcus morrilli Cockerell, 1914a: 110 .

Steatococcus morrilli (Cockerell) ; Ferris (1921: 69).

Crypticerya morrilli (Cockerell) ; Unruh & Gullan (2008: 26) .

Unmounted material. Adult female dark red to purplish-gray; antennae, legs and eyes brownish-black; dorsal surface covered in mealy white secretion; waxy tufts forming middorsal and marginal longitudinal rows (adapted from Cockerell, 1914a).

Slide-mounted material. Adult female elliptical to oval, widest across abdomen, 6.8–7.4 mm long, 5.0– 5.3 mm wide (imperfect lectotype 5.2 mm long, 4.6 mm wide). Antenna 10 or 11 segmented; segments V and VI fused. Eyes, mouthparts and legs as for tribe. Thoracic spiracles as for genus. Derm with bare patches on submedial head and thorax. Hair-like setae sparsely scattered on dorsal surface, denser on ventromedial surface; longest setae forming marginal clusters and between antennae. Flagellate setae distributed as for genus. Simple multilocular pores, each 12–13 µm in diameter, with bilocular centre and 8–12 outer loculi, clustered in dorsal medial to submedial longitudinal row and ventral marginal clusters on each segment. Simple multilocular pores, each 11–12 µm in diameter, with bilocular centre and 6–8 outer loculi, scattered across all body segments. Marsupium present, marsupial band shaped as for genus, except for two submedial bare patches on anterior edge, formed by sparse short hair-like setae and multilocular pores, with trilocular (sometimes bilocular or quadrilocular) centre and 6–10 outer loculi, forming band 7–9 pores wide. Simple multilocular pores, each 11–12 µm in diameter, with bilocular centre and 4–12 outer loculi and appearing slightly bluish when stained, scattered on medial to submedial head and thorax; similar pores scattered within marsupium, each 9–11 µm in diameter, with bilocular centre and 4–8 outer loculi. Vulvar opening as for genus, sur- rounded by hair-like setae and typical multilocular pores, each 13–15 µm in diameter, with trilocular centre and 10–12 outer loculi. Cicatrices, oval to reniform, numbering 3, central cicatrix hourglass shaped, lateral cicatrices reniform. Abdominal spiracles as for genus. Anal ring as for genus; anal opening surrounded by robust hair-like setae and typical multilocular pores, each 12–13 µm in diameter, with elongate or bilocular centre and 8–10 outer loculi. Very small tubercles present in submarginal longitudinal row on dorsal head and thorax; each tubercle with few short, robust hair-like setae.

First-instar nymph as for genus, except each abdominal segment with one submarginal pore, one submedial pore and one medial pore, long hair-like setae in each submarginal cluster very long and long hair-like setae at abdominal apex in 2 pairs.

Type data. USA: Arizona, Verde Valley, near Jerome, ex plant "superficially just like Viborquia spinosa ” (A.W. Morrill) .

Type material. Lectotype here designated: ad ♀, “ Palaeococcus / morrilli Ckll. /Type No. 18050 U.S. N.M.”//“ Palaeococcus / morrilli Ckll. /Type/ Arizona ” ( USNM) . Paralectotypes: 1 ad ♀, 6 embryonic larvae (same slide as lectotype); ca. 18 1 st -instar nymphs (one slide), ca. 20 1 st -instar nymphs (one slide), ca. 17 1 st -instar nymphs (one slide), “ Palaeococcus /morrilli/Ckll./ Type / Arizona / Type #18050” ( USNM) ; ad ♀, “ Palaeococcus morrilli Ckll. / From?/ Jerome, Arizona / From T.D.A. Ckll. / Entomological Laboratory / Stanford University /Type material”//“TYPE/MATERIAL” ( BME) ; 3 1 st -instar nymphs (one slide), 3 1 st -instar nymphs (one slide) “ Palaeococcus morrilli Ckll. /From?/ Jerome, Arizona / From T.D.A. Ckll. /1st. stage larva/Entomological Laboratory/Stanford University/Type material” ( BME) .

Taxonomic notes. Refer to the C. rileyi group for discussion of similar species.

The lectotype female is on the left side of the slide when the slide is held with the red label to the left. The red label on the lectotype slide has the words “Type No. 18050 U.S. N.M” typed on it. The slide with the firstinstar nymphs also has the word “Type” written on it. We chose the female designated here as lectotype from USNM although she is in poorer condition than a paralectotype housed at BME. We compared the writing on the slide-label of the lectotype with handwritten letters from Cockerell housed at BME and found the handwriting to be identical. Ferris’s handwriting is on the BME slide labels. We chose the lectotype from USNM material with Cockerell’s handwriting as we assume he examined that material when describing the species.
