( Figs. 13–16 View Figs )

Haideoporus texanus Young and Longley 1976: 788 View in CoL ; Longley and Spangler 1977: 532 (description of larvae); Bowles 1997: 297 (new distribution records); Nilsson 2001: 152; Larson et al. 2000: 138.

Type Species. Haideoporus texanus Young and Longley, 1976 View in CoL by original designation.

Type Locality. U.S.A., Texas, Hays County, San Marcos, Southwest Texas State University , Aquatic Station , artesian well .

Diagnosis. Haideoporus texanus can be distinguished from other Hydroporini by the following: 1) eyes small, located anterolaterally on head; 2) setae of body and legs extremely long; 3) pro- and mesocoxae large, globular; 4) prosternal process not extending posteriorly between mesothoracic legs to mesosternum.

Discussion. This species was discovered in a well on the campus of Texas State University in San Marcos, Hays County, Texas (Young and Longley 1976) and subsequently also found at Comal Spring, Comal County, Texas (Bowles and Stanford 1997), the type locality for C. stygius (see above). The larva of Haideoporus has been described (Longley and Spangler 1977), making it the only subterranean dytiscid larva from North America described to date.

Relationships. The species is currently placed in the Hydroporini ( Nilsson 2001) , but Young and Longley (1976) were cautious to make definitive statements about the relationships of this species to others in its subfamily. They pointed out close similarities of Haideoporus with other subterranean diving beetles, such as Morimotoa and Siettitia , but suspected that these similarities were due to convergence in similar habitats.
