Entomobrya katzi Jordana & Baquero in Baquero et al., 2021, nomen nudum.

TYPE MATERIAL. — Holotype. USA • ♀; Pennsylvania, Chester Co., Wayne; 40.0662, -75.3769; 130 m a.s.l.; 23.V.2011; A. Katz leg.; sweep of Forsythia sp. ; INHS 1007501 and INHS 10007502 (head and body in two different slides), code AK11-32.

Paratypes. USA • ♀ on two slides; INHS 1007503 and INHS 10007504 ; same data; AK11-32; A. Katz leg.; INHS • 8 undetermined sex on slides; INHS 1007505-1007520 ; same data; AK12- 50; A. Katz leg.; INHS • 12 in ethyl alcohol; INHS 1007521 ; 29.VI.2012; AK12-50; A. Katz leg.; INHS .

TYPE LOCALITY. — USA, Pennsylvania, Chester Co., Wayne, coordinates 40.0662, -75.3769; 130 m a.s.l.

ETYMOLOGY. —The specific epithet, katzi , is referred to Aron Katz, the Collembola researcher from USA who captured the specimens now described as new species and mentioned them in a paper in 2015.

DIAGNOSIS. — Yellow background, with longitudinal pigmentation (principally two bands: dorsolateral and lateral), multispinate labral papillae, 3-5 Mc on areas T1-T2 on Th II, 2-2/1-0-1 Mc on areas A1-A5 on Abd IIIII, and 0-4-1-2-2 on Abd IV. The unequivocal identification of the species can only be done using the abbreviated formula that, for this species, is: 3-2-0-1(2)-2/3-5/2-2/0-4-1-2-2 (following Jordana & Baquero 2005).

DESCRIPTION

Size and color

Ground color yellow, with pigment in a longitudinal patron on lateral head and body, dorsolateral Th II–Abd IV, two dorsal patches on Abd II, one on anterior Abd III, and a transversal pale stripe (W-shaped) on Abd IV (fig. 21 in Katz et al. 2015 https://doi.org/10.3897/zookeys.525.6020.figure21).

Head

Eight eyes, GH subequal and smaller than EF. Ant IV with simple apical vesicle and pin chaeta present; sensory organ of Ant III as usual for the genus. Prelabral chaetae ciliated; labral smooth. Labral papillae multispinose. Lateral process of labial papilla E slightly curved, thin, nearly reaching tip of papilla. Maxillary palp bifurcated, with three sublobal chaetae. Labial row with –MRELL, R 1/3 of M, all ciliated.

Body and legs

Length ratio of Abd IV/III c. 4. Trochanteral organ with approximately 31 chaetae. Tibiotarsus not sub-segmented, without smooth chaetae, except for smooth terminal chaeta on legs III. Claw with four teeth: paired at 50% and first unpaired at 75% from base; dorsal teeth basal. Empodium acuminate, with finely serrate external lamella (pe) in leg III. Tenent hair clavate. Manubrial plate with four (sometimes up to six) chaetae and two pseudopores. Sensillar formula from ThII to AbdV normal as in the rest of Entomobryinae ( Zhang & Deharveng 2015): 2,2/1,2,2,7 n,3; microsensillar formula from Th II to Abd III: 1,0/1,0,1.

Macrochaetotaxy

Simplified Mc formula: 3-2-0-1(2)-2/3-5/2-2/1-0-1/0-4-1- 2-2. Head: H1 area with Mc An2, An3a and An3; H2 area with Mc A5 and A6; S’0 absent (H3); H4 area with one Mc (S3), and S1 sometimes present; H4’ area with three Mc (S4, S5i and S5); H5 area with Ps2 and Ps5 as Mc. Mesothorax: area T1 with three Mc: m1, m2 and m2i; T2 with five Mc: m4, m4i, m4p, a5 and m5; a5’ present but small. Abdomen: Abd II area A1 with two Mc (a2 and a3); area A2 with two Mc (m3 and m3e); Abd III with one Mc on area A3 (a1), without Mc on A4, and another Mc on A5 (m3); Abd IV with or without Mc on A6 area (B1), four Mc on A7 (A2, B2, B3 and C1), one Mc on A8 (A4a), two Mc on A9 (A5 and B5), and two on A10 (A6 and B6).

REMARK

Most of the information in this addendum has been obtained from the work of Katz et al. (2015) in which a group of specimens was presented as belonging to the species E. intermedia , but considering their characters did not coincide with those of the specimens of E. intermedia described in Europe.
