Distribution. All known specimens are from Provincia de Guanacaste, in northwestern Costa Rica, ranging from 10–300 m in elevation.

Biology. Two of the 8 known specimens were taken with Malaise traps, other data are lacking. See Ślipiński (1989) for a review of the known biology of the genus.

Etymology. An arbitrary group of letters indicating the initials of the Instituto Nacional de Biodiversidad, Heredia, Costa Rica, whose efforts to document, understand, use and preserve the biodiversity of Costa Rica is honored with this name.

Diagnosis. The relatively large size, unmodified clypeus and admedian grooves, short submedian carina, uniform dark chocolate brown color, large eye, and deeply notched occipital groove ( Fig. 1 ) will distinguish this species from other Catogenus . Catogenus inbio will key to couplet 6 in Burckhardt and Ślipiński (2003), where it does not fit either couplet. Unlike C. collaris Sharp , the head, pronotum and elytra are uniformly dark chocolate brown and the elytra are less that 2.4 3 as long as wide (2.1–2.3). Unlike C. rufus Fabricius and C. thomasi Ślipiński , the head has strong, elongate admedian grooves. The eye is 1.3 3 as high as the diameter of the scape as in C. rufus , but the occiput is deeply notched, as in C. thomasi . Catogenus inbio is larger (9.5–13 mm) and darker than C. thomasi (8–9 mm). The apical piece of the median lobe (Fig. 4) differs from those of C. rufus and C. thomasi in the details of the shape and internal sac. For females, the spermatheca is diagnostic ( Fig. 3 ), being similar to those of C. rufus and C. thomasi , but somewhat longer and more slender in the arm relative to the size of the bulb ( Fig. 3 ).

To accommodate C. inbio , couplets 6 and 7 of the key to Catogenus in Burckhardt and Ślipiński (2003) should be replaced with the following:

6 Head and pronotum distinctly darker than elytra, head and pronotum almost black, elytra always reddish. Elytra 2.5–2.6 times as long as wide. Head with long and deep admedian grooves (Burckhardt and Ślipiński 2003, Fig. 300). Genitalia as in Burckhardt and Ślipiński (2003) Figs. 301–303.

New Records for Costa Rica

Previous published records for Costa Rican Passandridae include only Taphroscelidia linearis (LeConte) (Burckhardt and Ślipiński 2003). To this, we add 4 more here.

Two specimens of Catogenus rufus have been seen from Guanacaste Province, Costa Rica. One from a Malaise trap at 600 m at Estacion Maritza on the West side of Volcan Orosi [ INBIO] and 1 from 300 m at Los Alemendros, Parque Nacional Guanacaste, A.C.; Guanacaste [ MAIC] .

Catogenus castaneus is recorded from Mexico to Argentina, but has never been specifically recorded from Costa Rica (Burckhardt and Ślipiński 2003). Fourteen specimens were seen from Guanacaste and Puntarenas Provinces, ranging from 100– 800 m [INBIO, MAIC].

Catogenus rufus and C. castaneus are distinguished by details of the sublateral carina, the male genitalia and spermatheca, and, in the past, by the distribution. Catogenus rufus has not been reported south of Texas until this report (Burckhardt and Ślipiński 2003). With its discovery sympatric with C. castaneus in northwest Guanacate Province, Costa Rica, distribution is no longer diagnostic. One very useful but previously unreported character is the sculpture of the lateral portion of the prosternum between the procoxa and hypomeron, which is very strongly punctate in C. rufus but either impunctate and somewhat shagreened (females) or very weakly punctate (males) in C. castaneus.

A single Costa Rican specimen of Taphroscelidia rostrata (Sharp), previously reported only from Panamá (Burckhardt and Ślipiński 2003) is from Carara Biological Reserve in Puntarenas Province, taken in March 1991 (INBIO).

Passandra fasciata is one of the largest, most widespread, and commonly collected members of the family, known from Mexico and Cuba to Argentina, but has never been specifically recorded from Costa Rica. Thirty-four specimens from a variety of localities in Guanacase and Puntarenas Provinces were examined [INBIO, MAIC].
