Description.
Male head, face, legs, and abdomen white. Pronotum, scutellum, and wings with black spots and bands (
Fig. 18
). Head in dorsal view narrower than pronotum, crown much longer medially than next to eye; eyes as wide as or wider than distance between eyes (
Figs. 11−12
). Pronotum short, weakly projected anteriorly, marked with black dots at base or without marks. Mesonotum large, with pair of black maculae anteriorly (
Figs. 11−12
). Each forewing with five black spots in basal half, distal portion infused with black (
Fig. 9
).
Female as in male (
Fig. 19
), but dorsal spots smaller.
Male genitalia.
Abdominal apodemes well developed, large, broad at apex, extended to segment V (
Fig. 3
). Pygofer conical, longer than wide (
Figs. 1 and 4
); with dorsal preapical appendage slender, arising on distal ¾ of dorsal margin and extended posteromesad (
Fig. 2
). Apex of pygofer lobe with large black decurved hook extended along apical margin, with median ventral lobe (
Fig. 1
). Plates broad at base, and moderately tapered toward rounded tip, with lateral row of widely separated setae (
Fig. 7
). Connective U −shaped (
Fig. 5
). Style long, basal part thin, middle attached to connective with short lobes, preapical lobe rectangular with single seta, apex angled mesad, then posterad (
Fig. 5
). Aedeagus robust, preatrium short, shaft compressed, with paired slender sinuate processes as long as shaft, arising near base, not extended beyond apex; shorter, wider, single process, placed ventrally at middle of aedeagus, curved dorsad (
Fig. 6
).
Female genitalia.
Pygofer with long setae, sharply excavated at apex showing apical zone of gonoplacs (
Fig. 4
), and sternite VII straight −oblique (
Fig. 8
).

Phenology.
Specimens were collected in October, November, December, and January. Highest abundance was in December (Quezada-Daniel,
pers. comm.
).
Etymology.
This new species is named in honor of Dmitry Alexandrovich Dmitriev in recognition of his importance as a taxonomist on typhlocybines.
Distribution.
Morelos,
Mexico
(
Fig. 17
).
Host.
Avocado (
Persea americana
).
Remarks.
This species is similar to
I. minuenda
(see fig.
59 in
Young 1952
),
I. biforma
(see fig.
2 in
Ruppel & DeLong 1952
), and
I. gigantica
(see fig.
3 in
Ruppel & DeLong 1952
) in the structure of the aedeagus, but differs in having an additional process between the basal pair of aedeagal processes and the apex of the shaft (
Fig. 6
). It also differs in the structure of the pygofer processes (
Figs. 1−2
).
